Description

TECHNICAL FIELD

The present disclosure relates to a connector.

This application claims priority based on Japanese Application No. 2021-061220 filed on Mar. 31, 2021, and incorporates the entirety of the content described therein.

BACKGROUND

Patent Document 1 discloses a connector including a terminal module having a first terminal (electric contact member), a second terminal (external connection member), and a flexible conductor (braided wire) electrically connecting the first terminal and the second terminal to each other, and a connector housing accommodating the terminal module. In the terminal module, the first terminal is attached to a case that accommodates an elastic member (coil spring). The elastic member is sandwiched between a ceiling wall portion of the case and the first terminal. By fitting the connector and a partner connector together, the first terminal pressed by the partner connector (partner-side connector) moves toward the ceiling wall (ceiling wall portion) while compressing the elastic member. When the connector and the partner connector are fitted together, the ceiling wall is in contact with the connector housing. Furthermore, when the connector and the partner connector are fitted together, the elastic member is compressed compared to a state in which the connector and the partner connector are not fitted together. Since the compressed elastic member tries to return to its original state, it presses the ceiling wall toward the connector housing.

DETAILED DESCRIPTION TO EXECUTE THE INVENTION

<Problems to be Solved> Since the connector housing continues to be pressed by the ceiling wall while the connector and the partner connector are fitted together, the connector housing may deform over time. Therefore, the connector has room for further improvement in terms of durability.

An object of the present disclosure is to provide a connector that can improve durability.

<Effect of the Invention> According to the connector of the present disclosure, the effect of being able to improve durability is exhibited.

Description of Embodiments of the Present Disclosure

First, embodiments of the present disclosure will be listed and described.

(1) The connector of this disclosure is a connector configured to fit together with a partner connector relatively approaching along a first direction extending from one side to another side, and electrically connect to the partner connector, the connector including: a terminal module configured to electrically connect to the partner connector; a connector housing accommodating the terminal module; and a reinforcing member attached to the connector housing, in which the terminal module includes: a case including a ceiling wall and a pair of side walls extending from the ceiling wall to the one side; an elastic member that is accommodated in the case and is elastically deformable along the first direction; a first terminal that is supported by the pair of side walls while being biased toward the one side by the elastic member, and is movable to the other side by being pressed by the partner connector: a second terminal different from the first terminal; and a flexible conductor electrically connecting the first terminal and the second terminal to each other, the connector housing has a support wall to which the reinforcing member is attached, the support wall has a reinforcing surface that is in contact with the reinforcing member, and a contact surface that is arranged on a side opposite to the reinforcing surface and is capable of coming into contact with the ceiling wall after the connector is fitted together with the partner connector, and the reinforcing member has a higher rigidity than the supporting wall.

According to this configuration, the reinforcing member has higher rigidity than the supporting wall. The reinforcing member is attached to a support wall having a contact surface capable of coming into contact with the ceiling wall pressed by the elastic member. The reinforcing member supports the support wall from the side opposite to the ceiling wall. Therefore, it is possible to suppress deformation of the support wall pressed by the ceiling wall. Accordingly, the durability of the connector can be improved.

(2) It is preferable that the connector housing is made of a thermoplastic resin, and the reinforcing member is made of a metal.

According to this configuration, the connector housing is made of a thermoplastic resin, and the reinforcing member is made of a metal. From the viewpoint of moldability, the connector housing that accommodates the terminal module is preferably made of a thermoplastic resin. On the other hand, the support wall, which is part of the connector housing, is pressed against the ceiling wall, which is part of the terminal module, which is a heat source when electric current flows therethrough. Metals have superior shape stability in high-temperature environments compared to thermoplastic resins. Therefore, by supporting the supporting wall with the metal reinforcing member, it is possible to suppress deformation of the supporting wall pressed by the ceiling wall. Accordingly, it is possible to achieve both manufacturability and durability of the connector.

(3) It is preferable that the reinforcing member is integrated with the connector housing.

According to this configuration, the reinforcing member is integrated with the connector housing. Thus, it is possible to inhibit the reinforcing member from falling off of the connector housing. Accordingly, the durability of the connector can be improved.

(4) It is preferable that at least part of the reinforcing member is embedded in the connector housing.

According to this configuration, at least part of the reinforcing member is embedded in the connector housing. Thus, when assembling the connector, the worker does not need to attach the reinforcing member to the connector housing. Accordingly, the assembly workability of the connector can be improved.

(5) It is preferable that the reinforcing member has a fixing portion capable of being fixed to a housing of an in-vehicle device.

According to this configuration, the connector includes a fixing portion that can be fixed to the housing of the in-vehicle device. Thus, it is no longer necessary to prepare a separate component for fixing the connector to the vehicle-mounted device. Accordingly, the number of components of the connector can be reduced.

(6) It is preferable that a plurality of the terminal modules are provided, the plurality of terminal modules are accommodated in the connector housing in a state of being arranged side by side along a direction orthogonal to the first direction, and the reinforcing member overlaps with the respective ceiling walls of the plurality of terminal modules when viewed from the first direction.

According to this configuration, the connector housing accommodates a plurality of terminal modules. Furthermore, the reinforcing member overlaps with the ceiling walls of the plurality of terminal modules when viewed from the first direction. Therefore, the reinforcing member can collectively support the support walls that are pressed against the ceiling walls of the plurality of terminal modules. Accordingly, it is not necessary to provide a reinforcing member for each terminal module, and the number of components of the connector can be reduced.

Details of Embodiment of the Present Disclosure

A specific example of the connector of the present disclosure will be described below with reference to the drawings. In each drawing, part of the configuration may be exaggerated or simplified for convenience of description. Also, the dimensional proportion of each portion may differ in each drawing. Also, in some cases, only some of a plurality of identical members are given reference numerals, and the reference numerals are omitted for the other members. Also, in the present disclosure, “parallel” does not mean parallel in a geometrically strict sense, but is used in a wider sense within a range where the effect of the present invention is exhibited as long as it is regarded as parallel. Also, in the present disclosure, orthogonal does not mean orthogonal in a geometrically strict sense, but is used in a wider sense within a range where the effect of the present invention is exhibited as long as it is considered orthogonal.

<Overview of Connector 10 and Partner Connector 12>

As shown in FIGS. 1 and 2, the connector 10 and the partner connector 12 are respectively provided in the in-vehicle device 1 and the partner device 3, which are mounted in the vehicle. For example, the connector 10 is provided in a PCU (Power Control Unit: an example of the in-vehicle device 1) including an inverter circuit, and the partner connector 12 is provided in a motor (an example of the partner device 3).

The partner connector 12 is inserted into the connector 10 due to the partner connector 12 relatively approaching the connector 10 along a first direction extending from one side to another side. That is, the connector 10 and the partner connector 12 are fitted together, and the connector 10 and the partner connector 12 are electrically connected to each other. The PCU and the motor are electrically connected to each other via the connector 10 and the partner connector 12. The fitting between the connector 10 and the partner connector 12 will be described later.

<Connector 10>

The connector 10 includes terminal modules 14 and a connector housing 16. The terminal modules 14 are modules for electrically connecting partner terminals 124 included in the partner connector 12 and electric circuits (not shown) included in the in-vehicle device 1 to each other.

As shown in FIGS. 4, 5, and 8, the connector housing 16 accommodates the terminal modules 14. The connector housing 16 has a main body portion 64, a first lid portion 66, and a second lid portion 68. The terminal modules 14 are accommodated in a space between the body portion 64, the first lid portion 66, and the second lid portion 68. The terminal modules 14, the body portion 64, and the first lid portion 66 are arranged side by side in a direction orthogonal to the first direction. The body portion 64 and the second lid portion 68 are arranged side by side along the first direction.

<Terminal Module 14>

As shown in FIGS. 8 and 9, the terminal module 14 includes a case 20, an elastic member 18, a first terminal 22, a second terminal 42, and a flexible conductor 44. The configuration of each part of the terminal module 14 described below is a configuration of the connector 10 in a non-fitted-together state.

<Case 20>

As shown in FIG. 9, the case 20 has a ceiling wall 24, a pair of side walls 26, 26 extending from the ceiling wall 24, and a pair of elastic member holding walls 28, 28 extending from the ceiling wall 24. The case 20 is made of a metal, for example. The case 20 is made of stainless steel, for example. The case 20 accommodates the elastic member 18. In the case 20, for example, the ceiling wall 24, the pair of side walls 26, 26, and the pair of elastic member holding walls 28, 28 are formed in one piece by pressing a plate material.

The pair of side walls 26, 26 oppose each other. The direction in which the pair of side walls 26, 26 oppose each other is orthogonal to the first direction. The direction in which the pair of side walls 26, 26 oppose each other is orthogonal to the direction in which the main body portion 64 and the first lid portion 66 are arranged side by side.

In the following description, for convenience, the direction along the first direction will be referred to as the up-down direction. The direction in which the pair of side walls 26, 26 oppose each other will be referred to as the left-right direction. A direction orthogonal to the first direction and the direction in which the pair of side walls 26, 26 oppose each other will be referred to as the front-rear direction. That is, the direction in which the main body portion 64 and the first lid portion 66 are arranged side by side will be referred to as the front-rear direction. In the following description, for the sake of convenience, in the up-down direction, the other side will be referred to as upward, and the one side will be referred to as downward. In the front-rear direction, the body portion 64 side will be referred to as frontward, and the first lid portion 66 side will be referred to as rearward.

The ceiling wall 24 is a flat plate-shaped region provided along the front-rear direction and the left-right direction. The widths of the ceiling wall 24 in the front-rear direction and the left-right direction are greater than the widths of the elastic member 18 in the front-rear direction and the left-right direction. The ceiling wall 24 covers the elastic member 18 when viewed from above in the vertical direction.

The pair of side walls 26, 26 are a pair of walls that are parallel to each other and extend downward from the edges in the left-right direction of the ceiling wall 24. The pair of side walls 26, 26 have shapes that are mirror-symmetrical to each other. The right side wall 26 will be representatively described below. As shown in FIG. 9, the side walls 26 each have a base portion 26A, a first leg portion 26B, a second leg portion 26C, and guide projections 26D.

The base portion 26A is a region continuous with the ceiling wall 24. The base portion 26A has the same width as the ceiling wall 24 in the front-rear direction. The base portion 26A has a function of receiving the elastic member 18 that bends in the left-right direction when the elastic member 18 is compressed or stretched.

The first leg portion 26B extends downward from the base portion 26A at the central portion of the base portion 26A in the front-rear direction, and is inclined frontward. The width of the first leg portion 26B in the vertical direction is longer than the inclination width of the first leg portion 26B in the front-rear direction. The first leg portion 26B has a smaller width than the base portion 26A in the front-rear direction. The first leg portion 26B has, for example, a width about one-fourth that of the base portion 26A. The first leg portion 26B has a first receiving portion 26B1 extending frontward at its lower end portion. The upper surface of the first receiving portion 26B1 is a surface extending along the front-rear direction. A rear surface of the first leg portion 26B functions as a guide surface 26B2 that guides the first terminal 22 when the partner connector 12 is fitted. Since the guide surface 26B2 extends downward while being inclined in the front-rear direction, the first terminal 22 is guided in the up-down direction as well as in the front-rear direction along the guide surface 26B2.

The second leg 26C extends downward from the base portion 26A. The second leg portion 26C is positioned rearward of the first leg portion 26B. The second leg portion 26C is spaced apart from the first leg portion 26B in the front-rear direction. The second leg portion 26C has a smaller width than the base portion 26A in the front-rear direction. The second leg portion 26C has, for example, a width about one-fourth that of the base portion 26A. The second leg portion 26C has a second receiving portion 26C1 and a lower end portion 26C2. The second receiving portion 26C1 is arranged above the lower end portion 26C2. The second receiving portion 26C1 protrudes rearward relative to the lower end portion 26C2. The upper surface of the second receiving portion 26C1 is a surface extending along the front-rear direction.

The guide projections 26D protrude rightward from the base portion 26A. The guide projections 26D protrude from the base portion 26A toward the side opposite to the elastic member 18. The guide projections 26D are formed by bending portions of the side wall 26 rightward. For example, the guide projections 26D are each formed by bending the side wall 26 rightward between a pair of slits 27, 27, and since the slits 27, 27 are provided on both the upper and lower sides of the guide projection 26D, the guide projection 26D is easily bent rightward.

The guide projections 26D are arranged above the first leg portion 26B. The guide projections 26D are arranged above the second leg portion 26C. One guide projection 26D is provided frontward of the side wall 26 and one guide projection 26D is provided rearward of the side wall 26. The guide projection 26D arranged frontward of the side wall 26 and the guide projection 26D arranged rearward of the side wall 26 overlap each other when viewed from the front-rear direction. The position of the upper surface of the guide projection 26D arranged frontward of the side wall 26 is equal to the position of the upper surface of the guide projection 26D arranged rearward of the side wall 26. The position of the lower surface of the guide projection 26D arranged frontward of the side wall 26 is equal to the position of the lower surface of the guide projection 26D arranged rearward of the side wall 26.

The pair of elastic member holding walls 28, 28 are a pair of walls that are parallel to each other and extend downward from the edges in the front-rear direction of the ceiling wall 24. The pair of elastic member holding walls 28, 28 have a width smaller than that of the ceiling wall 24 in the left-right direction. The pair of elastic member holding walls 28, 28 have, for example, a width about one-third of the width of the ceiling wall 24 in the left-right direction. The pair of elastic member holding walls 28, 28 have a smaller width than the side wall 26 in the up-down direction. The pair of elastic member holding walls 28, 28 have, for example, a width about half that of the side wall 26 in the vertical direction. As shown in FIG. 8, the inner surfaces of the pair of elastic member holding walls 28, 28 in the front-rear direction oppose the side portions in the front-rear direction of the elastic member 18 with slight gaps therebetween. The pair of elastic member holding walls 28, 28 have the function of receiving the elastic member 18 that bends in the front-rear direction when the elastic member 18 is compressed or stretched.

<Elastic Member 18>

The elastic member 18 is a coil spring formed by winding a wire made of a metal into a coil shape. The elastic member 18 is made of stainless steel, for example.

As shown in FIG. 9, the elastic member 18 is accommodated in the case 20. That is, the elastic member 18 is surrounded by the ceiling wall 24, the pair of side walls 26, 26, and the pair of elastic member holding walls 28, 28. The elastic member 18 is sandwiched between the ceiling wall 24 and the first terminal 22 while being compressed in the up-down direction. The elastic member 18 biases the first terminal 22 downward. The elastic member 18 biases the ceiling wall 24 upward. In this state, the elastic member 18 can be further compressed in the up-down direction. That is, the elastic member 18 is compressed by the ceiling wall 24 and the first terminal 22 in a range shorter than the free length of the spring and longer than the length of the spring during maximum compression.

The elastic member 18 has a first end portion 18a and a second end portion 18b. The first end portion 18a is a region of approximately one turn from the upper end of the elastic member 18. The first end 18a is in contact with the ceiling wall 24. The second end portion 18b is a region of about one turn from the lower end of the elastic member 18. The second end portion 18b is in contact with the first terminal 22.

<First Terminal 22>

As shown in FIGS. 7 to 10, the first terminal 22 is a terminal capable of physically coming into contact with the partner terminal 124. As shown in FIGS. 8 and 9, the first terminal 22 is attached to the pair of side walls 26, 26. The first terminal 22 is supported by the pair of side walls 26, 26 while being biased downward by the elastic member 18. The first terminal 22 has a first portion 22a, a second portion 22b, a first surface 22A, and a second surface 22B arranged on the side opposite to the first surface 22A. The first terminal 22 is made of a metal. The first terminal 22 is made of a copper alloy, for example. In the first terminal 22, the first portion 22a and the second portion 22b are formed in one piece by pressing a plate material.

The first portion 22a is arranged spaced apart downward from the ceiling wall 24. The first portion 22a is provided parallel to the ceiling wall 24. That is, the first portion 22a extends along the front-rear direction and the left-right direction. The second portion 22b extends upward from the rearward edge of the first portion 22a. Thus, the first terminal 22 has an L shape when viewed from the left-right direction. The first portion 22a has a pair of first engaging portions 58, 58 and a pair of guided portions 62, 62. The second portion 22b has a pair of second engaging portions 60, 60.

The first surface 22A of the first portion 22a is in contact with the second end 18b of the elastic member 18. The first surface 22A of the first portion 22a functions as a receiving surface for receiving the second end portion 18b of the elastic member 18. The second surface 22B of the first portion 22a functions as a contact surface capable of coming into contact with a partner contact 128 included in the partner terminal 124.

The first engaging portion 58 is a region that protrudes outward in the left-right direction at the front edge of the first portion 22a. The first engaging portion 58 comes into contact with the first receiving portion 26B1 of the first leg portion 26B from above. The first engaging portion 58 comes into contact with the upper surface of the first receiving portion 26B1. The first engaging portion 58 is received by the first receiving portion 26B1.

The guided portion 62 is a region that protrudes outward in the left-right direction at the central portion in the front-rear direction of the first portion 22a. The guided portion 62 is inserted between the first leg portion 26B and the second leg portion 26C. When the connector 10 is fitted together with the partner connector 12, the guided portion 62 is guided in the vertical direction as well as in the front-rear direction along the guide surface 26B2.

The first surface 22A of the second portion 22b is a surface facing toward the elastic member 18. The second surface 22B of the second portion 22b is a surface facing away from the elastic member 18. The flexible conductor 44 is connected to the second surface 22B of the second portion 22b.

The second engaging portion 60 protrudes outward in the left-right direction. The second engaging portion 60 is arranged below the central portion in the up-down direction of the second portion 22b. The second engaging portion 60 comes into contact with the second receiving portion 26C1 of the second leg portion 26C from above. The second engaging portion 60 comes into contact with the upper surface of the second receiving portion 26C1. The second engaging portion 60 is received by the second receiving portion 26C1.

Downward movement of the first terminal 22 is restricted due to the first engaging portion 58 coming into contact with the first receiving portion 26B1 and the second engaging portion 60 coming into contact with the second receiving portion 26C1. That is, the first terminal 22 is sandwiched between the elastic member 18 and the pair of side walls 26, 26 in the non-fitted-together state. In the non-fitted-together state, the first terminal 22 is sandwiched between the elastic member 18, the pair of first receiving portions 26B1, 26B1, and the pair of second receiving portions 26C1, 26C1.

<Second Terminals 42>

The second terminals 42 are attached to the connector housing 16. The second terminals 42 are held at a position above the first terminals 22 by the connector housing 16.

The upper portion 42A is arranged outside of the connector housing 16. The upper portion 42A is a region connected to an electrical circuit (not shown). The lower portion 42B is a region extending downward from the upper portion 42A. The lower portion 42B is located inside the connector housing 16. The flexible conductor 44 is connected to the lower portion 42B. The constricted portion 42C is a region recessed inward in the left-right direction at the boundary region between the upper portion 42A and the lower portion 42B. The constricted portion 42C fits together with the connector housing 16 through recess-protrusion fitting.

<Flexible Conductor 44>

The flexible conductor 44 is a conductor that has flexibility. As shown in FIG. 8, the flexible conductor 44 electrically connects the first terminal 22 and the second terminal 42 to each other. The flexible conductor 44 is a conductor that is more flexible than the first terminal 22. The flexible conductor 44 is a conductor that is more flexible than the second terminal 42. The flexible conductor 44 can be repeatedly deformed.

The flexible conductor 44 is, for example, a band-shaped braided wire obtained by braiding a plurality of conductive metal strand wires together.

The fitting portions 130 have shapes that protrude upward. The fitting portions 130 support the partner terminals 124 on their upper surfaces.

<Fitting Between Connector 10 and Partner Connector 12>

The manner in which the partner connector 12 is fitted to the connector 10 will be described with reference to FIGS. 8, 9, 7, and 10. When the partner connector 12 moves upward and approaches the connector 10, the partner terminals 124 and the fitting portions 130 of the partner connector 12 pass through the partner terminal insertion holes 122 and enter the connector housing 16. Then, the partner contacts 128 of the partner terminals 124 come into contact with the second surfaces 22B of the first terminals 22. Note that when the partner connector 12 is fitted together with the connector 10, the connector 10 and the partner connector 12 need only relatively approach each other in the up-down direction, and the connector 10 may move downward to approach the partner connector 12.

When the partner connector 12 moves further upward after the partner contacts 128 comes into contact with the second surfaces 22B, the first terminals 22 are pressed by the partner contacts 128, whereby the first terminals 22 move upward while compressing the elastic members 18. The deformation of the flexible conductors 44 allows the first terminals 22 to move upward. At this time, the guided portions 62 of the first terminals 22 slide on the guide surfaces 26B2 of the first leg portions 26B. Accordingly, the first terminals 22 move upward and move rearward by the amount that the guide surfaces 26B2 are inclined in the front-rear direction. Since the width of the guide surfaces 26B2 in the up-down direction is longer than the width by which the guide surfaces 26B2 are inclined in the front-rear direction, the amount of upward movement of the first terminals 22 during fitting is larger than the amount of rearward movement.

The second surfaces 22B of the first terminals 22 moving rearward slide in the front-rear direction on the partner contacts 128 moving upward. As a result, foreign matter adhering between the second surfaces 22B and the partner contacts 128 is removed. Examples of the foreign matter include films of sulfides, oxides, and the like formed on the surfaces of the second surfaces 22B.

Then, when the partner connector 12 moves further upward, the partner connector 12 is fitted to the connector 10. In this state, the first portions 22a of the first terminals 22 receive a downward biasing force from the elastic members 18 and an upward pressing force from the partner contacts 128. The first portions 22a of the first terminals 22 are sandwiched between the elastic members 18 and the partner contacts 128 in the up-down direction. Due to the first portions 22a being pressed against the partner contacts 128 by the elastic members 18 in this manner, the first terminals 22 can be more reliably electrically connected to the partner contacts 128.

As shown in FIGS. 7 and 8, after the connector 10 and the partner connector 12 are fitted together, the straight-line distance between the first joint portions 52 and the second joint portions 48 becomes shorter accompanying the upward movement of the first terminals 22. Accordingly, as the first terminals 22 move upward, the flexible conductors 44 are deformed, and the amount of bending of the flexible conductors 44 increases. Accordingly, the flexible conductors 44 tend to swing more easily after the connector 10 and the partner connector 12 are fitted together than before the connector 10 and the partner connector 12 are fitted together. That is, the flexible conductors 44 tend to swing more easily when the connector 10 and the partner connector 12 are fitted together than when the connector 10 and the partner connector 12 are not fitted together. The flexible conductors 44 can enter the bulging portions 102 when the connector 10 and the partner connector 12 are fitted together. The flexible conductors 44 can enter the recesses 78 when the connector 10 and the partner connector 12 are fitted together.

As shown in FIG. 7, when the connector 10 and the partner connector 12 are fitted together, the cases 20 are in contact with the contact surfaces 64D1. When the connector 10 and the partner connector 12 are fitted together, the ceiling walls 24 are in contact with the contact surfaces 64D1. When the connector 10 and the partner connector 12 are fitted together, the elastic members 18 bias the ceiling walls 24 toward the support wall 64D. When the connector 10 and the partner connector 12 are fitted together, the elastic members 18 press the ceiling walls 24 toward the support wall 64D. In the state where the connector 10 and the partner connector 12 are fitted together, the ceiling walls 24 are supported by the support wall 64D and the reinforcing member 64F.

The first terminals 22 are in contact with the partner contacts 128 when the connector 10 and the partner connector 12 are fitted together. The elastic members 18 bias the first terminals 22 toward the partner connector 12 when the connector 10 and the partner connector 12 are fitted together. The first terminals 22 are pressed toward the partner connector 12 when the connector 10 and the partner connector 12 are fitted together. The first terminals 22 are supported by the partner connector 12 when the connector 10 and the partner connector 12 are fitted together.

Next, the operations and effects of this embodiment will be described.

(1) The reinforcing member 64F has higher rigidity than the supporting wall 64D. The reinforcing member 64F is attached to the support wall 64D having the contact surface 64D1 capable of coming into contact with the ceiling walls 24 pressed by the elastic members 18. The reinforcing member 64F supports the support wall 64D from the side opposite to the ceiling walls 24. Accordingly, it is possible to suppress deformation of the support wall 64D pressed by the ceiling walls 24. Accordingly, durability of the connector 10 can be improved.

(2) The connector housing 16 is made of a thermoplastic resin, and the reinforcing member 64F is made of a metal. From the viewpoint of moldability, the connector housing 16 that accommodates the terminal modules 14 is preferably made of a thermoplastic resin. On the other hand, the ceiling walls 24, which are part of the terminal modules 14, which are a heat source when current flows therethrough, are pressed against the support wall 64D, which is part of the connector housing 16. Metals have superior shape stability in high-temperature environments compared to thermoplastic resins. Thus, by supporting the supporting wall 64D with the reinforcing member 64F made of a metal, it is possible to suppress deformation of the supporting wall 64D pressed by the ceiling walls 24. Accordingly, both manufacturability and durability of the connector 10 can be achieved.

(3) The reinforcing member 64F is integrated with the connector housing 16. Thus, it is possible to inhibit the reinforcing member 64F from falling off from the connector housing 16. Accordingly, durability of the connector 10 can be improved.

(4) At least part of the reinforcing member 64F is embedded in the connector housing 16. Thus, when assembling the connector 10, there is no need for an operator to attach the reinforcing member 64F to the connector housing 16. Accordingly, the assembly workability of the connector 10 can be improved.

(5) The fixing portions 64F1 are included, which can be fixed to the housing 2 of the vehicle-mounted device 1. Thus, it is not necessary to prepare a separate component for fixing the connector 10 to the vehicle-mounted device 1. Accordingly, the number of components of the connector 10 can be reduced.

(6) The reinforcing member 64F overlaps with the ceiling walls 24 of the plurality of terminal modules 14 when viewed from the first direction. The connector housing 16 accommodates the plurality of terminal modules 14. Thus, the reinforcing member 64F can collectively support the support wall 64D that is pressed against the ceiling walls 24 of the plurality of terminal modules 14. Accordingly, it is not necessary to provide the reinforcing member 64F for each terminal module 14, and the number of components of the connector 10 can be reduced.
