Description

  The present invention relates to a connector.

  The connector disclosed in Patent Document 1 includes a housing and a spring member. A contact portion is provided at the front end of the spring member. In the process of fitting the housing with the mating housing, the spring projection is contracted by the stopper projection provided on the mating housing being brought into contact with the contact portion of the spring member, and the elastic force is stored. When the housing is properly fitted with the mating housing, the abutment part is dissociated from the stopper projection, the elastic force of the spring member is released, and the spring member is elastically restored to its original natural state. On the other hand, when the fitting operation is stopped before the housing is properly fitted with the counterpart housing, the counterpart housing is pushed back by being biased by the released spring member. As a result, it is possible to avoid a situation in which the housing is left in a semi-fitted state with the counterpart housing.

Japanese Patent No. 3741356

  By the way, according to the above configuration, since the resin surface of the stopper protrusion of the mating housing contacts the metal surface of the spring member, the stopper protrusion may be damaged, and in the worst case, the stopper protrusion may be scraped off. If it does so, the reliability of the function which detects the fitting state of a connector will fall. On the other hand, by attaching a separate cap (sometimes referred to as a stopper) to the front end of the spring member so that the stopper projection comes into contact with the cap, the stopper projection can be protected. For example, it is known that a spring member is assembled to a detection member and a cap is attached to the front end of the spring member. However, with such a configuration, a cap is required separately from the detection member, which increases the number of parts. On the other hand, when the cap is abolished and the front and rear walls of the spring member chamber are received by the front and rear walls of the detection member, a slide mold that is pulled out in the direction intersecting the front-rear direction is required when forming the spring housing chamber. There is also a situation that molding becomes complicated.

  The present invention has been completed based on the above circumstances, and provides a connector that ensures the reliability of fitting detection, prevents the number of parts from increasing, and is easy to mold. With the goal.

  The connector of the present invention is a housing that can be fitted to a mating housing, and is movably assembled to the housing, and integrally connects the first member and the second member to the first and second members. A detecting member having a hinge, and a first housing member and a second housing member facing each other in a fitting direction of the housing. Housed in the spring housing chamber, one end side in the fitting direction is received by the first member, and the other end side in the fitting direction is received by the second member. When the first member is pressed against the counterpart housing and approaches the second member side, the elastic force is accumulated, and when the two housings are properly fitted, the stored elastic force is released, and the first, First Characterized in place with a spring member to separate the members together, a.

  Since the first and second members are integrally connected via the hinge, it is possible to prevent the number of parts from increasing. Further, since the counterpart housing does not press the first member by pressing the first member, the counterpart housing is prevented from being damaged. Thereby, the reliability of the connector fitting detection by the detection member can be ensured. Furthermore, since the first and second members are connected via hinges, the first and second members are positioned in a direction intersecting with the fitting direction when forming the spring accommodating chamber, so that the fitting direction is obtained. Since it is not necessary to use a slide mold that is pulled out in the intersecting direction, the complexity of molding is also eliminated.

Similarly, the first member is a plan view of the detection member in a closed position with respect to the second member. Similarly, it is a front view of the detection member in which the first member is in the closed position with respect to the second member.

Hereinafter, preferred embodiments of the present invention will be shown.
The spring member is a coil spring, and the first member has a support protrusion that enters into an opening on one end side in the fitting direction of the coil spring. The coil spring is stably supported by the first member by the support protrusion. If the first and second members are fixed in a state of facing each other, the support protrusion must be formed at a position facing the second member, which makes it difficult to form the support protrusion. However, according to this configuration, the first and second members are connected via the hinge, and the first and second members can be positioned in the direction intersecting the fitting direction when forming the support protrusion. The above difficulty is eliminated.

  The housing is provided with a guide portion for guiding the displacement of the first member. According to this, the stability of the displacement operation of the first member is ensured by the guide portion.

  The spring members are provided in pairs in the width direction, and the hinges are provided so as to be bent along the width direction. Thereby, it is avoided that the connector becomes large in the height direction intersecting with the width direction.

  The hinge 44 has a flexible band shape, and as shown in FIG. 9, one end is integrally connected to the front end of the second member 42 along the vertical direction of the second member 42, and the other end is the rear end of the first member 43. The rear end of the first member 43 is integrally connected to the rear end in the closed position.

  As shown in FIG. 10, in the open position, the first member 43 is spaced apart in the width direction of the second member 42, and the hinge 44 is disposed linearly obliquely rearward from the first member 43 to the second member 42. Is done. As shown in FIG. 11, in the closed position, the first member 43 is disposed in front of the second member 42 so as to face the second member 42, and the hinge 44 is disposed so as to be bent substantially in an L shape. Further, as shown in FIGS. 6 to 8, in the closed position, the first and second members 43 and 42 form a cylinder substantially closed at both front and rear ends. A spring accommodating chamber 55 is formed. In the process from the open position to the closed position, the first member 43 can be rotated substantially along the width direction, and the hinge 44 can be bent substantially along the width direction. The detection member 40 is molded with the first member 43 in the open position with respect to the second member 42.

  As shown in FIG. 6, the rear end surface (the rear end surface in the closed position) of the first member 43 is a first spring receiving portion 61 that receives the front end of the spring member 80 in the closed position. The first spring receiving portion 61 is configured to receive a substantially upper half portion of the front end of the spring member 80. As shown in FIGS. 6 and 11, the first spring receiving portion 61 has a substantially conical first support protrusion 62 that protrudes backward into the front end opening 80A of the spring member 80 in the closed position. Is provided.

The above is the structure of the connector of the first embodiment. Next, the function and effect of the first embodiment will be described.
First, the first and second members 43 and 42 are set in the open position, and the spring member 80 is inserted into the second member 42 from the front through the insertion opening 58 (see FIGS. 9 and 10). At this time, the second support protrusion of the second spring receiving portion 59 enters the inside of the rear end opening 80B of the spring member 80, and the rear end of the spring member 80 is supported by the second member 42.

  Subsequently, the first member 43 is rotated so as to be reversed along the width direction via the hinge 44 to reach the closed position (see FIGS. 11 and 12). When the first member 43 reaches the closed position, the first support protrusion 62 of the first spring receiving portion 61 enters the inside of the front end opening 80A of the spring member 80, and the front end of the spring member 80 is supported by the first member 43. Is done. Thus, the spring member 80 is held in the spring accommodating chamber 55 of the first and second members 43 and 42 in a state of being prevented from coming off.

  Next, the detection member 40 is inserted into the assembly space 24 of the housing 10 and the detection member 40 is assembled at the standby position. In the standby position, the locking protrusion 53 of the locking piece 52 is elastically locked to the first locking portion 27 of the housing 10, thereby restricting the detection member 40 from moving backward (FIG. 2). See). Further, at the standby position, the bridging portion 49 of the second plate portion 46 abuts on the beam portion 22 of the housing 10 to restrict the detection member 40 from moving forward. Further, in the standby position, the guide protrusions 56 of the first member 43 are fitted into the guide grooves 21 of the housing 10 to restrict the movement of the detection member 40 in the width direction (see FIG. 6). . Further, at the standby position, the spring member 80 is supported by the first and second spring receiving portions and is generally kept in a natural state.

  In this state, the mating housing 90 is fitted into the housing 10. In the fitting process of the two housings 10 and 90, the pressing portion 93 of the mating housing 90 abuts on the first member 43 of the detection member 40, and the first member 43 is pressed by the pressing portion 93 so as to approach the second member 42. (Refer to FIGS. 6 and 7). At this time, the guide protrusion 56 of the first member 43 slides on the groove surface of the guide groove 21 so that the backward movement of the first member 43 is performed smoothly. In the process of retracting the first member 43, the spring member 80 is pressed by the first member 43 and contracted in the front-rear direction, and an elastic force is stored in the spring member 80.

  Further, in the fitting process of the housings 10 and 90, the lock projection 25 interferes with the lock portion 99, and the lock arm 19 is bent and deformed (see FIG. 3). When the two housings 10 and 90 are properly fitted, the lock arm 19 is elastically restored, and the lock protrusion 25 is disposed so as to be able to lock the lock portion 99 (see FIG. 4). Thereby, both the housings 10 and 90 are held in a state in which they are regulated to be separated from each other.

  As the two housings 10 and 90 are properly fitted, the upper edge of the front end of the hood 92 of the mating housing 90 interferes with the locking projection 53, and the locking projection 53 is lifted while bending the locking piece 52 ( (See FIG. 4). Thereby, the latching between the latching protrusion 53 and the first latching portion 27 is released. When the locking projection 53 is separated from the first locking portion 27, the above-stored elastic force is released at once, and the spring member 80 extends toward the natural state (see FIGS. 5 and 8). Then, the second member 42 is pushed by the spring member 80 and retracts, and the detection member 40 reaches the detection position. At the detection position, the bridging portion 49 of the detection member 40 abuts against the stopper 26 of the lock arm 19 (see FIG. 5), and the locking portion 57 of the detection member 40 is disposed so as to be locked to the second locking portion 28. (See FIG. 8). This prevents the detection member 40 from falling off the housing 10. Further, at the detection position, the raised portion 54 of the detection member 40 is positioned below the arm main body 23 of the lock arm 19, and the bending operation of the arm main body 23 is restricted by the raised portion 54 (see FIG. 5).

  On the other hand, when the fitting operation is stopped at the half-fitting position until both housings 10 and 90 are properly fitted, the elastic force of the spring member 80 accumulated until the two housings 10 and 90 are stopped is released, and the mating housing 90 is pressed by the first member 43 and pushed back in a direction away from the housing 10. Thereby, the situation where both the housings 10 and 90 are kept in a half-fitting position is avoided.

  According to the first embodiment, since the first and second members 43 and 42 are integrally connected to each other via the hinge 44, compared to the case where the first and second members 43 and 42 are separate parts, It is possible to prevent the score from increasing. In particular, when the spring accommodating chamber 55 of the detection member 40 is formed, the first and second members 43 and 42 are arranged side by side in the width direction intersecting with the fitting direction, so that the slide is pulled out in the direction intersecting with the fitting direction. This eliminates the need for a mold and eliminates the complexity of molding. Further, the front end of the spring member 80 is covered with the first member 43, and the mating housing 90 presses the first member 43 and the spring member 80 is contracted in the process of fitting the two housings 10, 90. Is prevented from coming into contact with the spring member 80, and the resin surface of the mating housing 90 is prevented from being damaged.

  Further, since the first member 43 has the first support protrusion 62 that enters the front end opening 80 </ b> A of the spring member 80, the front end of the spring member 80 is stably supported by the first support protrusion 62. In particular, since the first and second members 43 and 42 are formed side by side in the width direction intersecting the fitting direction, the first and second support protrusions face each other in the front-rear direction in the closed position. Even if there is a circumstance that the first and second support protrusions are arranged, the first and second support protrusions can be formed without hindrance.

  Further, since the hinge 44 can be bent along the width direction, and the first and second members 43 and 42 are arranged side by side in the width direction in the open position, the connector is prevented from becoming large in the height direction. Is done.
