The present disclosure relates to a connector.
A connector disclosed in Patent Document 1 is provided with a female housing and a male housing connectable to each other, a slide member movably supported on the male housing and a coil spring arranged between the slide member and the male housing. The female housing includes a lock arm for holding the both housings (female housing and male housing) in a connected state. The front end of the coil spring is in contact with the slide member and the rear end of the coil spring is in contact with the male housing.
If the both housings are incompletely connected, the lock arm is resiliently deformed and comes into contact with the slide member. The slide member moves back by being pushed by the female housing. If the slide member moves back, the coil spring is contracted between the slide member and the male housing. If a connecting operation of the both housings is stopped in this stage, the female housing is pushed back by a biasing force of the coil spring. Thus, the both housings are separated without being left incompletely connected. If the both housings are properly connected, the lock arm resiliently returns to be separated from the slide member. The slide member is moved forward by the biasing force of the coil spring.
Patent Document 1: JP 2018-195423 A
When the both housings are in the incompletely connected state, a male terminal accommodated in the male terminal starts to be inserted into a female terminal accommodated in the female housing. Here, if a worker stops the connecting operation of the both housings and the both housings are separated, the connecting operation of the both housings has to be performed again. As a result, the number of sliding movements of contact points of the both terminals (female terminal and male terminal) increases more than necessary and contact wear may occur between the both terminals.
Accordingly, the present disclosure aims to provide a connector provided with a function of guaranteeing connection having high connection reliability.
The present disclosure is directed to a connector with a first housing, a second housing connectable to the first housing, a slider to be supported on the first housing, the slider being relatively movable with respect to the first and second housings, and a biasing member to be resiliently deformably arranged between the slider and the first housing, the first housing including a contact portion, the slider including a slider lock portion, the second housing including a stopper portion for stopping a connecting operation of the first and second housings by coming into contact with the contact portion while the slider is being pushed toward the second housing and a slider lock receiving portion for stopping push-in of the slider by being locked by the slider lock portion, and the biasing member having a biasing force for pushing the first housing toward a connection position to the second housing when the slider lock receiving portion is locked by the slider lock portion and contact between the stopper portion and the contact portion is released.
According to the present disclosure, it is possible to provide a connector provided with a function of guaranteeing connection having high connection reliability.
First, embodiments of the present disclosure are listed and described.
(1) The connector of the present disclosure is provided with a first housing, a second housing connectable to the first housing, a slider to be supported on the first housing, the slider being relatively movable with respect to the first and second housings, and a biasing member to be resiliently deformably arranged between the slider and the first housing, the first housing including a contact portion, the slider including a slider lock portion, the second housing including a stopper portion for stopping a connecting operation of the first and second housings by coming into contact with the contact portion while the slider is being pushed toward the second housing and a slider lock receiving portion for stopping push-in of the slider by being locked by the slider lock portion, and the biasing member having a biasing force for pushing the first housing toward a connection position to the second housing when the slider lock receiving portion is locked by the slider lock portion and contact between the stopper portion and the contact portion is released.
According to the above configuration, since the stopper portion comes into contact with the contact portion and the connecting operation of the first and second housing is stopped while the slider is being pushed toward the second housing, it is possible to prevent the start of a connecting operation of the both terminals accommodated in the first and second housings. As a result, the occurrence of unnecessary contact wear between the both terminals can be prevented and connection reliability can be enhanced.
When the slider lock receiving portion is locked by the slider lock portion and the contact between the stopper portion and the contact portion is released, the first housing can reach the connection position to the second housing by being pushed by the biasing force of the biasing member.
On the other hand, if the push-in of the slider is stopped before the slider lock receiving portion is locked by the slider lock portion, the slider is pushed back in a direction separating from the second housing by the biasing force of the biasing member. As a result, it is possible to prevent a situation where the first and second housings are left in an incompletely connected state before reaching the connection position. Note that the “connection position” means the positions of the first and second housings when the both terminals accommodated in the first and second housings are properly connected.
(2) Preferably, the slider includes a restricting portion for keeping the contact between the stopper portion and the contact portion by pressing the stopper portion. According to this configuration, the contact between the stopper portion and the contact portion can be reliably maintained while the slider is being pushed toward the second housing. By the separation of the restricting portion from the stopper portion, the pressing of the stopper portion can be automatically released.
(3) The slider may include a frame-like frame portion behind a surface on a rear side of the first housing when a moving side of the first housing toward the connection position to the second housing is a front side and a side opposite to the front side is the rear side. According to this configuration, the first and second housings can reach a connected state by pushing the frame portion. Here, since the frame portion is frame-like, a wide push-in region (gripping region) can be secured. Further, a wire and the like can be inserted inside the frame portion.

When the slider 12 is at the standby position, the lock body portions 61 of the slider lock portions 59 are inserted into the extension grooves 40 of the receptacle 35. When the slider 12 is at the push-in position, the lock body portions 61 of the slider lock portions 59 are fit and locked into the slider lock receiving portions 39. When the first and second housings 10, 11 are at the connection position, the lock body portions 61 are arranged to be exposed on an outer surface side of the receptacle 35 as shown in
<Biasing Members>
As shown in
<Connection Procedure of First and Second Housings>
The slider 12 is assembled with the first housing 10 from behind. As shown in
The first housing 10 and the slider 12 are inserted into the receptacle 35 of the second housing 11. By pushing the slider 12 forward (toward the push-in position, toward the second housing 11) while holding the frame portion 49, the connecting operation of the first and second housings 10, 11 can be performed.
With the slider 12 shallowly inserted in the receptacle 35, the lock body portions 61 of the slider lock portions 59 are inserted into rear parts of the extension grooves 40 of the receptacle 35. Further, with the first housing 10 shallowly inserted in the receptacle 35, the stopper portion 32 is inserted into the through hole 19 and, as shown in
Also while the connecting operation of the first and second housings 10, 11 is stopped, the push-in of the slider 12 is continued. Since the resilient displacement of the stopper portion 32 is suppressed by the restricting portion 54 during this time, contact between the stopper portion 32 and the contact portion 29 is maintained. By pushing the slider 12, the slider-side supporting portions 62 approach the housing-side supporting portions 63 and the biasing members 13 arranged between the slider-side supporting portions 62 and the housing-side supporting portions 63 are contracted.
Before the slider 12 reaches the push-in position, the lock body portions 61 come into contact with the closing portions 41 and the slider lock portions 59 are resiliently deformed inwardly (toward the rail portions 57) with the base end portions 60 as fulcrums as shown in
When the slider 12 reaches the push-in position, the restricted portion 33 of the stopper portion 32 passes through the restricting body 55 of the restricting portion 54. Further, the contacted portion 34 rides on the contact portion 29 and the stopper portion 32 is resiliently deformed, whereby the restricted portion 33 enters the escaping portion 56. Thereafter, the contacted portion 34 passes through the contact portion 29 and the stopper portion 32 resiliently returns, whereby the restricted portion 33 is retracted from the escaping portion 56. In this way, the contact between the stopper portion 32 and the contact portion 29 is released.
Further, while the slider 12 is moving from the standby position to the push-in position, the biasing members 13 are gradually contracted to accumulate biasing forces. If the push-in of the slider 12 is stopped such as by a worker leaving a hand from the slider 12 before the slider 12 reaches the push-in position, the slider 12 is pushed back by receiving the biasing forces of the biasing members 13. That is, the biasing members 13 elongate rearward with the housing-side supporting portions 63 as support points and forces in a direction separating from the second housing 11 are applied to the slider 12. At this time, the connecting operation of the first and second housings 10, 11 is stopped and a connecting operation of the first and second terminal fittings 14, 15 is not started. Thus, according to this embodiment, a situation where the first and second housings 10, 11 are left in an incompletely connected state can be prevented.
When the slider 12 reaches the push-in position, the slider lock portions 59 are locked to the slider lock receiving portions 39 and the contact between the stopper portion 32 and the contact portion 29 is released, the first housing 10 is moved forward by the biasing forces of the biasing members 13. That is, the biasing members 13 elongate forward with the slider-side supporting portions 62 as support points. As the biasing members 13 elongate forward, the first housing 10 relatively moves toward the connection position to the second housing 11 by receiving the biasing forces of the biasing members 13.
Specifically, if the biasing members 13 elongate forward with the slider-side supporting portions 62 as support points, the housing-side supporting portions 63 are pressed by the biasing members 13 and the first housing 10 automatically moves toward the back side of the receptacle 35. After the slider 12 reaches the push-in position in this way, the connecting operation of the first and second housings 10, 11 proceeds at once by the biasing forces of the biasing members 13.
When the first and second housings 10, 11 reach the connection position, the lock projection 27 is fit into the lock groove 37 as shown in
As described above, according to this embodiment, the stopper portion 32 comes into contact with the contact portion 29 and the connecting operation of the first and second housings 10, 11 is stopped while the slider 12 is being pushed from the standby position to the push-in position, whereby it is possible to set a state where the connecting operation of the first and second terminal fittings 14, 15 is not started. As a result, the occurrence of unnecessary contact wear between the first and second terminal fittings 14, 15 can be prevented and connection reliability can be enhanced.
In a state where the slider lock receiving portions 39 are locked by the slider lock portions 59 and the contact between the stopper portion 32 and the contact portion 29 is released after the slider 12 reaches the push-in position, the first housing 10 can be pushed by the biasing forces of the biasing members 13 and quickly reach the connection position to the second housing 11.
On the other hand, if the push-in of the slider 12 is stopped before the slider lock receiving portions 39 are locked by the slider lock portions 59, the slider 12 is pushed back in the direction separating from the second housing 11 by the biasing forces of the biasing members 13. As a result, it is possible to prevent a situation where the first and second housings 10, 11 are left in the incompletely connected state before reaching the connection position.
Further, since the slider 12 includes the restricting portion 54 for keeping the contact between the stopper portion 32 and the contact portion 29 by pressing the stopper portion 32, the contact between the stopper portion 32 and the contact portion 29 can be reliably maintained while the slider 12 is being pushed from the standby position to the push-in position. On the other hand, by the separation of the restricting portion 54 from the stopper portion 32 after the slider 12 reaches the push-in position, the pressing of the stopper portion 32 can be automatically released. Further, since the slider 12 includes the frame-like frame portion 49 behind the rear surface of the housing body 16 of the first housing 10, a wide push-in region (gripping region) can be secured.
The embodiment disclosed this time should be considered illustrative in all aspects, rather than restrictive.
In the case of the above embodiment, the first terminal fitting is a female terminal fitting, into which the tab is insertable, and the second terminal fitting is a male terminal including the tab. However, contrary to the above embodiment, the first terminal fitting may be a male terminal fitting including a tab and the second terminal fitting may be a female terminal fitting, into which the tab is insertable, as another embodiment. If the first terminal fitting is a male terminal fitting, the first housing may be shaped to include a receptacle.
In the case of the above embodiment, the first lock portion is resiliently deformably provided and the second lock portion is projection-like and fixedly provided. However, contrary to the above embodiment, the first lock portion may be projection-like and fixedly provided and the second lock portion may be resiliently deformably provided as another embodiment.
Although the biasing member is constituted by a coil spring in the case of the above embodiment, the biasing member may be constituted by any one of a leaf spring, a torsion spring, a resin spring and rubber as another embodiment.
Although the escaping portion is shaped as a hole penetrating through the restricting portion in the case of the above embodiment, the escaping portion may be a bottomed recess open in the lower surface (surface facing the contact portion) of the restricting portion and closed on the upper surface of the restricting portion.
