This application is based on and claims priority from Japanese Patent Application No. 2023-215533, filed on Dec. 21, 2023, with the Japan Patent Office, the disclosure of which is incorporated herein in its entirety by reference.
The present disclosure relates to a connector and a connector unit.
A connector disclosed in JP 2023-117578A includes a male terminal with a tab, a hood portion inside which the tab protrudes, and a moving plate attached inside the hood portion. Before the connector is fitted to a counterpart connector, the moving plate positions the tab inside the hood portion. Even if foreign matter enters the hood portion before the fitting of the connector, the foreign matter comes into contact with the moving plate, thus making it possible to avoid the breakage and the like of the tab. JP S54-036787U discloses a technology for coupling the side surfaces of two housings to each other.
In JP 2023-117578A, every connector includes the moving plate, and there is a concern of an increase in the cost compared with a connector provided with no moving plate. In addition, it is necessary to ensure a space in which the moving plate can be attached inside the hood portion, and therefore, it is difficult to apply such a configuration to a small-sized connector. In contrast, if the connector does not include the moving plate, there is a problem in that the tab cannot be protected.
Therefore, it is an object of the present disclosure to provide a connector and a connector unit capable of protecting the tab and enabling a reduction in size and cost.
A connector of the present disclosure is a connector including: a terminal fitting with a tab; and a hood portion inside which the tab protrudes, wherein the hood portion includes a first latching portion and a second latching portion having shapes capable of being locked to each other, the first latching portion includes a portion protruding forward beyond an opening edge on a front surface of the hood portion, and the first latching portion and the second latching portion are located at positions symmetrical about a point or with respect to a line when the hood portion is viewed from a front side.
A connector unit of the present disclosure is a connector unit including two connectors of the same type or different types, wherein each of the two connectors includes: a terminal fitting with a tab; and a hood portion inside which the tab protrudes, one connector of the two connectors includes, on the hood portion, a first latching portion having a portion protruding forward beyond an opening edge on a front surface of the hood portion, and the other connector includes a second latching portion, and in a state in which the opening edges of the two connectors are abutted against each other, the first latching portion of the one connector is locked to the second latching portion of the other connector.
With the present disclosure, it is possible to provide a connector and a connector unit capable of protecting the tab located inside the hood portion and enabling a reduction in size and cost.
The foregoing summary is illustrative only and is not intended to be in any way limiting. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features will become apparent by reference to the drawings and the following detailed description.
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.
First, aspects of the present disclosure will be listed and described.
For example, at the time of transfer or the like during a harness production process, when the opening edges of two connectors are abutted against each other, the first latching portion of one connector can be locked to the second latching portion of the other connector and the second latching portion of the one connector can be locked to the first latching portion of the other connector. This makes it possible to couple the two connectors to each other. The tabs are disposed inside the hood portions of the coupled connectors in a state in which the tabs are protected from foreign matter from the outside. Accordingly, with the configuration of (1) above, the tab located inside the hood portion can be protected even if the connector does not include the moving plate. Since the connector does not include the moving plate, the cost can be accordingly reduced, and this configuration is also applicable to a small-sized connector. Note that the “locking” in the description above refers to a state in which two connectors whose opening edges have been abutted against each other are latched to each other so as to remain coupled to and not to separate from each other.
With the configuration of (2) above, when the first latching portion and the second latching portion are formed, it is unnecessary to process elastic locks and the like, and the processability is excellent. Also, it is possible to couple the two connectors simply by abutting the opening edges of the two connectors against each other.
With the configuration of (3) above, the force with which the first latching portion and the second latching portion are locked (coupled) to each other can be improved without complicating the shapes of the first latching portion and the second latching portion.
With the configuration of (4) above, a plurality of pairs of one first latching portion and one second latching portion can improve the reliability with which the two connectors remain coupled to each other when the opening edges of the connectors are abutted against each other.
With the configuration of (5) above, an operator can easily recognize the orientation of the connector with respect to the vertical direction and the left-right direction by checking the positions of the first latching portion and the second latching portion at the opening edge of the hood portion. As a result, it is possible to change the orientation of the connector to the corresponding orientation and fit it to a counterpart connector, thus making it possible to speed up the fitting operation.
For example, at the time of transfer or the like during a harness production process, two connectors of the same type or different types are coupled to each other via the first latching portions and the second latching portions by abutting the opening edges of the connectors against each other, and, inside the hood portions of the connectors, the tabs can be protected from foreign matter from the outside. The connector need not include the moving plate in order to protect the tab, thus making it possible to reduce the size and cost of the connector accordingly. Note that the “locking” in the description above refers to a state in which two connectors whose opening edges have been abutted against each other are latched to each other so as to remain coupled to and not to separate from each other.
The following describes specific examples of the present disclosure with reference to the drawings. Note that the present invention is not limited to these examples and is defined by the scope of the appended claims, and all changes that fall within the same essential spirit as the scope of the claims are intended to be included therein.

Each of the second latching portions 33 is formed as a recessed portion having a recessed shape (specifically a circular shape in a front view) that is recessed in the front surface 39 of the hood portion 20. The back end surface in the depth direction (the surface that is located at the rear end in the front-rear direction and faces forward) of the second latching portion 33 is arranged extending along the left-right direction and the vertical direction. The interior circumferential surface of the second latching portion 33 extends continuously with a constant diameter in the front-rear direction, except for the front end portion, which will be described later. The diameter of the front end portion of the interior circumferential surface of the second latching portion 33 gradually increases toward the front surface 39 of the hood portion 20. The second latching portion 33 is formed in a shape complementary to the shape of the first latching portion 32. In this Embodiment 1, the first latching portion 32 is fitted into the second latching portion 33. The press-fitting ribs 35 come into tight contact with the interior circumferential surface of the second latching portion 33 in a press-fitted state.
A plurality of first latching portions 32 protrude from the front surface 39 of the hood portion 20. Also, a plurality of second latching portions 33 are recessed in the front surface 39 of the hood portion 20, and the number of first latching portions 32 and the number of second latching portions 32 are the same. Specifically, the first latching portions 32 are formed at two positions spaced apart from each other in the left-right direction on the front surface 39 of the upper wall portion 22 of the hood portion 20. The second latching portions 33 are formed at two positions spaced apart from each other in the left-right direction on the front surface 39 of the lower wall portion 23 of the hood portion 20.

Before the connector 10 is fitted to a counterpart connector (e.g., at the time of transfer during a harness production process, or when the connector 10 is placed temporarily), two connectors 10A and 10B with the above-described structure are arranged in a state in which their openings face each other and one connector 10A is inverted 180 degrees relative to the other connector 10B in the vertical direction (see
In the connector unit 60, the opening of the hood portion 20 of the one connector 10A is blocked by the other connector 10B, and the opening of the hood portion 20 of the other connector 10B is blocked by the one connector 10A. As a result, the insides of the hood portions 20 of the connectors 10A and 10B are sealed. A plurality of tabs 91 protrude inside the hood portions 20 of the connectors 10A and 10B. With this configuration, foreign matter from the outside of the connector 10 is prevented from entering the hood portion 20, thus making it possible to avoid the breakage of and damage to the tabs 91.
Prior to the completion of a harness, just before the connector 10 is fitted to a counterpart connector, a force is applied to the connectors 10A and 10B in a direction in which the connectors 10A and 10B are detached from each other to separate them from each other. The connectors 10A and 10B are then fitted to corresponding counterpart connectors.
As described above, the connector 10 of this Embodiment 1 includes the terminal fittings 90 each having the tab 91, and the hood portion 20 inside which the tabs 91 protrude. The hood portion 20 includes the first latching portion 32 and the second latching portion 33 having shapes capable of being locked to each other. The first latching portion 32 protrudes forward beyond the opening edge on the first surface 39 of the hood portion 20. The first latching portion 32 and the second latching portion 33 are located at positions symmetrical with respect to a point in a front view of the hood portion 20.
The connector unit 60 of this Embodiment 1 is constituted of two connectors 10A and 10B of the same type, and each of the two connectors 10A and 10B includes the terminal fittings 90 each having the tab 91, and the hood portion 20 inside which the tabs 91 protrude. Out of the two connectors 10A and 10B, one connector 10A includes, on the hood portion 20, the first latching portion 32 protruding forward beyond the opening edge on the front surface 39 of the hood portion 20, and the other connector 10B includes the second latching portion 33. In a state in which the opening edges of the two connectors 10A and 10B are abutted against each other, the first latching portion 32 of the one connector 10A is locked to the second latching portion 33 of the other connector 10B.
For example, at the time of transfer or the like during a harness production process, when the opening edges of the two connectors 10A and 10B are abutted against each other, the first latching portion 32 of the one connector 10A can be locked to the second latching portion 33 of the other connector 10B. This makes it possible to couple the two connectors 10A and 10B to each other. The tabs 91 are disposed inside the hood portions 20 of the coupled connectors 10A and 10B in a state in which the tabs 91 are protected from foreign matter from the outside. Accordingly, with the configuration above, the tabs 91 can be protected even if the connector 10 does not include the moving plate. Since the connector 10 does not include the moving plate, the cost can be accordingly reduced, and this configuration is also applicable to a small-sized connector.
In this Embodiment 1, the first latching portion 32 has a protruding shape that protrudes from the front surface 39 (opening edge) of the hood portion 20, and the second latching portion 33 is formed in the front surface 39 of the hood portion 20 and has a recessed shape to which the first latching portion 32 can be fitted. With this configuration, when the first latching portion 32 and the second latching portion 33 are formed, it is not necessary to process elastic locks and the like, and the processability is excellent. Also, the opening edges of the two connectors 10A and 10B can be easily abutted against each other.
In this Embodiment 1, the press-fitting ribs 35 with a shape capable of coming into contact with the interior circumferential surface of the second latching portion 33 are formed on the exterior circumferential surface of the first latching portion 32. With this configuration, the force with which the first latching portion 32 and the second latching portion 33 are locked (coupled) to each other can be improved without complicating the shapes of the first latching portion 32 and the second latching portion 33.
In this Embodiment 1, a plurality of pairs of one first latching portion 32 and one second latching portion 33 are provided, and the first latching portion 32 and the second latching portion 33 in each pair are located at positions symmetrical about the center C1 of the opening of the hood portion 20 with the center C1 being a rotation center. With this configuration, the reliability with which the two connectors 10A and 10B remain coupled to each other can be improved when the opening edges of the connectors 10A and 10B are abutted against each other.
In addition, in this Embodiment 1, the first latching portions 32 are aligned in the left-right direction on the front surface 39 of the upper wall portion 22 of the hood portion 20, and the second latching portions 33 are aligned in the left-right direction on the front surface 39 of the lower wall portion 23 of the hood portion 20. With this configuration, an operator can easily recognize the orientation of the connector 10 with respect to the vertical direction by checking that the first latching portions 32 and the second latching portions 33 are located on the upper wall portion 22 and the lower wall portion 23 of the hood portion 20, respectively. As a result, it is possible to change the orientation of the connector 10 to the corresponding orientation and fit it to a counterpart connector, thus making it possible to speed up the fitting operation.
As shown in
The connector 10 is provided with one first latching portion 32 and one second latching portion 33. As shown in
The height positions of the first latching portion 32 and the second latching portion 33 are the same as those of the central portions in the vertical direction of the two side wall portions 24. The first latching portion 32 and the second latching portion 33 are located as a pair at positions symmetrical with respect to a symmetry axis S1 passing through the center in the left-right direction of the opening of the hood portion 20.
At the time of transfer or the like during a harness production process, two connectors 10A and 10B having the structure above are disposed with the openings thereof facing each other. Next, the front surfaces 39, which are the opening edges, of the hood portions 20 of the connectors 10A and 10B are abutted against each other. Then, as shown in
With this Embodiment 2, similarly to Embodiment 1 above, the tabs 91 disposed inside the hood portions 20 of the connectors 10A and 10B are protected from foreign matter from the outside. Since the connector 10 does not include the moving plate, the cost can be accordingly reduced, and this configuration is also applicable to a small-sized connector.
As shown in
Two connectors 10A and 10B that are of the different type as described above are coupled to each other to form a connector unit 60. The basic structures of the two connectors 10A and 10B are the same as that of the connector 10 of Embodiment 1 above. As shown in
