The terminals are retained by a lance member that projects from an inner wall of the terminal housing section.
[Patent Document 1] Japanese Unexamined Patent Application Publication No. 2016-9527
The connector has been demanded to be further downsized recently according to a configuration where the connector is mounted. This may lead the terminals that are arranged in the connector to be also downsized. For example, if the terminals to which the wires are connected by crimping with a wire barrel are used, the terminals are inserted in the terminal housing section of the housing after the crimping. In such a case, very thin wires of a small diameter are connected to the downsized terminals and therefore, the wires may be bent or warped when inserting the terminals into the terminal housing section.
The technology described herein was made in view of the above circumstances. An object is to provide a connector that can be downsized and suppress bending or warping of a wire.
A connector disclosed herein includes a terminal that is to be contacted with a conductive member of a wire, a housing in which the terminal is arranged, and a holding member that is fit in the housing and in contact with the terminal to hold a position of the terminal. At least one of the terminal and the housing includes a pressing portion that presses the conductive member in a direction such that the conductive member comes in contact with the terminal.
According to the above configuration, the pressing portion presses the conductive member in a direction such that the conductive member comes in contact with the terminal after the conductive member of the wire is disposed on the terminal. Therefore, the problems such as bending or warping of the wire are less likely to be caused even with the downsized connector and the downsized terminal. The connector described before can be downsized while restricting the occurrence of the bending or warping of the wire. However, connection errors may occur between the terminal and the wire due to the wrong positioning of the pressing portion with respect to the conductive member since the connector is configured such that the pressing portion presses the conductive member in a direction such that the conductive member comes in contact with the terminal to connect the conductive member to the terminal. According to the above configuration, since the holding member that is to be mounted in the housing comes in contact with the terminal to keep the position of the terminal, the connection errors that may be caused between the terminal and the wire due to the wrong positioning of the pressing portion with respect to the conductive member are less likely to be caused.
Embodiments of the technology described herein may preferably include configurations as follows.
The terminal may include a holding portion that holds the conductive member while being in contact with the conductive member and a pressing portion that is a separate component from the holding portion and presses in a direction such that the holding portion holds the conductive member.
According to such a configuration, the wire can be connected to the terminal by moving the holding portion and the pressing portion relatively each other after setting the holding portion and the pressing portion in the housing. Therefore, the bending or warping of the wire can be restricted in a configuration including the downsized connector and the downsized terminal.
The pressing portion may be sandwiched between the housing and the holding member to be positioned.
According to such a configuration, since the pressing portion is positioned between the housing and the holding member, the holding portion can keep holding the conductive member of the wire via the pressing portion. This can simplify the configuration of the connector.
One of the housing and the holding member may include a fitting stopper that is fit to another one of the housing and the holding member while keeping a position of the terminal and a provisional fitting stopper that is provisionally fit to the other one of the housing and the holding member while not keeping the position of the terminal.
According to such a configuration, the housing and the holding member that are provisionally fit each other can be made in the fitting state. This can simplify the fitting operation of the connector.
The terminal may include a jig receiver that is configured to receive a jig when the holding member is provisionally fit in the housing, and the jig receiver that receives the jig may allow a relative position of the holding portion and the pressing portion to be moved with sliding.
Accordingly, the relative movement of the holding portion and the pressing portion becomes easy.
The holding member may include a body member that is to be in contact with the terminal, a cover member that is pivotably connected to the body member via a hinge portion, and a disposing portion that protrudes from the body member toward the cover member and on which the wire is disposed. The cover member may include a wire pressing portion that presses the wire disposed on the disposing portion toward the disposing portion.
According to such a configuration, even if the wire receives a force in a direction such that the terminal is to be removed, the wire pressing portion presses and holds the wire. This reduces stress that may be caused in a connection portion of the wire and the terminal.
According to the technology disclosed herein, the connector can be downsized and bending or warping of a wire can be suppressed.

Next, the covers 13 are removed from the end portions of the wires 11 such that the conductive members 12 are exposed therefrom. The obtained wires 11 are inserted in the terminal insertion holes 63 of the holding member 60 and through the space between the pressing portions 31A and 31B and between the holding portions 26A and 26B. As illustrated in
Next, the holding member 60 is moved frontward with respect to the inner housing 41. Then, the fitting between the provisional fitting stopper 47 and the holding member 60 is released and the fitting frames 72 that are in contact with the fitting stoppers 48 are deformed and warped. Accordingly, the fitting frames 72 are fit to the fitting stoppers 48 and become in a fitting state. Then, the wires 11 are tied up and the tape 81 is wound around the wires 11 with using a space provided by opening the pair of cover members 74A, 74B (
Next, the one cover member 74A is moved to be closed and the tying band 82 is inserted through the through holes 77 and the wires 11 wrapped with the tape 81 are tied up with the tying band 82. The other cover member 74B is moved to be closed and the cover fitting portions 79 and the cover fitting pieces 76 of the one cover member 74A are fit to the cover fitting stoppers 80 and the receivers 78 of the other cover member 74B (see
According to the embodiment, following operations and effects are obtained.
The connector 10 includes the terminals 20 that are contacted with the conductive members 12 of the wires 11, the housing 40 in which the terminals 20 are arranged, and the holding member 60 that is mounted to the housing 40 and contacted with the terminals 20 to keep the positions of the terminals 20. One of the terminals 20 and the housing 40 includes the pressing portions 31A, 31B that press the conductive member 12 in a direction such that the conductive member 12 comes in contact with the terminal 20.
According to the present embodiment, the pressing portions 31A, 31B press the conductive member 12 in a direction such that the conductive member 12 comes in contact with the terminal 20 after the conductive member 12 of the wire 11 is disposed on the terminal 20. Thus, the wires 11 are connected to the terminals 20. Therefore, compared to a configuration in which the terminals are inserted in the housing after the terminals are connected to the ends of the wires 11 by crimping, the problems such as bending or warping of the wires 11 are less likely to be caused even with the downsized connector 10 and the downsized terminals 20. The connector 10 described before can be downsized while restricting the occurrence of the bending or warping of the wires. However, connection errors may occur between the terminals 20 and the wires 11 due to the wrong positioning of the pressing portions 31A, 31B with respect to the conductive member 12 since the connector 10 is configured such that the pressing portions 31A, 31B press the conductive member 12 in a direction such that the conductive member 12 comes in contact with the terminal 20 to connect the conductive member 12 to the terminal 20. According to the present embodiment, since the holding member 60 that is to be mounted in the housing 40 comes in contact with the terminals 20 to keep the position of the terminals 20, the connection errors that may be caused between the terminals 20 and the wires 11 due to the wrong positioning of the pressing portions 31A, 31B with respect to the conductive member 12 are less likely to be caused.
The terminal 20 includes the holding portions 26A, 26B and the pressing portions 31A, 31B that are separate components from the holding portions 26A, 26B. The holding portions 26A, 26B sandwich the conductive member 12 while being in contact with the conductive member 12.
According to such a configuration, the wires 11 can be connected to the terminals 20 by moving the holding portions 26A, 26B and the pressing portions 31A, 31B relatively each other after setting the holding portions 26A, 26B and the pressing portions 31A, 31B in the housing 40. Therefore, the bending or warping of the wires 11 can be restricted in a configuration including the downsized connector 10 and the downsized terminals 20.
The pressing member 30 including the pressing portions 31A, 31B is sandwiched between the housing 40 and the holding member 60 and positioned.
According to such a configuration, since the pressing member 30 is positioned between the housing 40 and the holding member 60, the holding portions 26A, 26B can keep holding the conductive member 12 of the wire 11 therebetween via the pressing member 30. This can simplify the configuration of the connector 10.
One of the housing 40 and the holding member 60 includes the fitting stopper 48 and the provisional fitting stopper 47. The fitting stopper 48 is fit to another one of the housing 40 and the holding member 60 while fixing the position of the holding portions 26A, 26B and the pressing portions 31A, 31B. The provisional fitting stopper 47 is provisionally fit to the other one of the housing 40 and the holding member 60 while not fixing the position of the holding portions 26A, 26B and the pressing portions 31A, 31B.
According to such a configuration, the housing 40 and the holding member 60 that are provisionally fit each other can be made in the fitting state. This can simplify the fitting operation of the connector 10.
One of the terminal body portion 21 and the pressing member 30 includes the jig receiver 33A where the jig J can be contacted with pressure while the holding member 60 and the housing 40 being provisionally fit each other. The jig receiver 33A that receives the jig J can relatively move the terminal body portion 21 and the pressing member 30 with sliding.
Accordingly, the relative movement of the terminal body portion 21 and the pressing member 30 becomes easy.
The holding member 60 includes the body member 61, the cover members 74A, 74B, and the disposing portion 70. The body member 61 is to be in contact with at least one of the terminal body portion 21 and the pressing member 30. The cover members 74A, 74B are connected to the body member 61 via the hinge portions 73 so as to be pivoted around the hinge portions 73 and cover the wires 11. The disposing portion 70 protrudes from the body member 61 toward the cover members 74A, 74B and the wires 11 are disposed on the disposing portion 70. The cover members 74A, 74B include the wire pressing portions 75, respectively, that press the wires 11 disposed on the disposing portion 70 toward the disposing portion 70.
According to such a configuration, even if the wire 11 receives a force in a direction such that the terminal 20 is to be removed, the wire pressing portions 75 press and hold the wire 11. This reduces stress that may be caused in a connection portion of the wire 11 and the terminal 20.
