Description

  The present invention relates to a lever-type connector.

  A waterproof connector used in a vehicle such as an automobile includes, for example, a terminal fitting, a connector housing that houses the terminal fitting, a seal member that secures waterproofing in the connector housing, and a rear holder that holds the seal member on the connector housing. ing. A seal member made of rubber or the like is press-fitted into the connector housing, and is retained so as not to be detached by attaching a rear holder from the rear. The same number of through holes as the terminal fittings are formed in the sealing member, and the terminal fittings connected to the electric wires are press-fitted and penetrated into the through holes of the sealing member held in the connector housing, It is possible to pull out the electric wire to the outside while ensuring the waterproofness in the connector housing.

  By the way, in order to assemble the waterproof connector having such a configuration, a terminal fitting is press-fitted into the seal member in a state where the seal member is compressed in the connector housing. In order to press-fit the terminal fitting into the compressed seal member, a higher terminal insertion force is required than in the case where the terminal fitting is not compressed, and the burden on the operator is large. In order to solve this problem, a waterproof connector described in Patent Document 1 is known as a device having a reduced terminal insertion force.

  In this waterproof connector, a seal member and a rear holder are fitted into a connector housing using a rotating lever. The pivot lever is pivotally supported by the connector housing, and is provided with a cam groove and a cam projection. The mating connector is provided with a projection that engages with the cam groove, and the rear holder is provided with a pair of clamping projections that clamp the cam projection. The mating connector and the rear holder are disposed at positions facing each other with the connector housing interposed therebetween, and a seal member is disposed between the rear holder and the connector housing. In addition, the rear holder and the seal member are inserted with the terminal fitting and the electric wire previously connected to the terminal fitting, and the terminal fitting in the penetrating state is accommodated in the connector housing.

  When the turning lever is turned, the mating connector and the rear holder sandwiching the seal member between the connector housing are simultaneously fitted into the connector housing, and the seal member is pushed into the connector housing by the rear holder. Installed. According to such a configuration, since the terminal fitting can be pre-pressed into a non-compressed seal member, terminal insertion is performed as compared with the case where the terminal fitting is press-fit after the seal member is mounted on the connector housing. The force can be reduced.

JP 2004-288500 A

  However, according to such a configuration, although the terminal insertion force can be reduced, the mating connector and the rear holder sandwiching the seal member are simultaneously fitted to the connector housing by the rotating lever, so that the rotating lever can be operated. Great power is required.

  The present invention has been completed based on the above circumstances, and an object thereof is to reduce lever operating force.

  The present invention relates to a connector housing that can be mated with a mating connector, a rear holder that can be mated from the opposite side of the connector housing to which the mating connector is mated, and fitting of the rear holder with the connector housing. A seal member disposed on the mating surface; a fitting operation lever disposed to be displaceable between an initial position and a fitting position with respect to the connector housing; the mating connector and the fitting operation lever; A connector cam pin projecting from one of the above, a connector cam groove formed on the other and engageable with the connector cam pin, and projecting from either the rear holder or the fitting operation lever. A rear holder cam pin formed on the other side and engageable with the rear holder cam pin. Inducing each cam pin along each cam groove by causing each cam pin to enter the entrance of each cam groove of the fitting operation lever and displacing the fitting operation lever to the fitting position. A lever-type connector capable of bringing the rear holder and the mating connector into a properly fitted state, wherein each of the cam grooves has a working portion for displacing the mating connector and the rear holder in the fitting direction; A non-acting portion for holding the mating connector and the rear holder without being displaced, and the acting portion of the connector cam groove corresponds to the non-acting portion of the rear holder cam groove, and the rear holder cam groove The operation portion is formed so as to correspond to the non-operation portion of the connector cam groove.

  According to such a configuration, the working portion of the connector cam groove is formed to correspond to the non-working portion of the rear holder cam groove, and the working portion of the rear holder cam groove is formed to correspond to the non-working portion of the connector cam groove. Therefore, by displacing the fitting operation lever to the fitting position, either the mating connector or the rear holder can be fitted to the connector housing first, and then the other can be fitted. In this way, displacement in the mating direction of the mating connector and the rear holder is alternately performed along the displacement direction of the mating operation lever, so that the mating connector and the rear holder are mated at the same time. The maximum value of the operating force required per unit displacement of the fitting operation lever can be reduced.

  Further, when fitting the mating connector and the rear holder at the same time, the lever operating force can be reduced by reducing the displacement of the mating connector and the rear holder in the fitting direction per unit displacement. In this case, it is necessary to increase the total length of the cam groove that guides the mating connector and the rear holder in the fitting direction. On the other hand, according to the lever-type connector of the present invention, the lever operating force can be reduced without increasing the overall length of the cam groove, so that space can be saved.

  The fitting operation lever is a slide lever that is displaceable in a direction crossing a fitting direction of the mating connector and the rear holder, and when the slide lever is displaced from the initial position toward the fitting position. First, the cam pins are simultaneously guided to the working portion of the connector cam groove and the non-working portion of the rear holder cam groove so that the mating connector is fitted into the connector housing, and then the connector It is desirable that the cam pins are simultaneously guided to the non-acting portion of the cam groove for the rear and the acting portion of the cam groove for the rear holder so that the rear holder is fitted to the connector housing.

  If the fitting operation lever is a slide lever, the shape of each cam groove can be simplified as compared with the case where, for example, a rotation lever is applied. Further, since the rear holder is fitted into the connector housing with the seal member interposed therebetween, the lever operating force required for fitting the rear holder is less than the lever operating force required for fitting the mating connector. There is a high possibility that it will become larger as the member is pressed. Therefore, by fitting the mating connector first, the fitting operation lever is urged in the fitting position direction, and the rear operation unit is displaced in the fitting direction by operating the fitting operation lever with the force applied. By doing so, the operability of the lever can be improved, and the lever operating force required as a total can be reduced.

  A rib protruding from the outer periphery of the rear holder in a direction orthogonal to the fitting direction is formed at a rear end portion in the fitting direction of the rear holder, and the rib is formed at a fitting portion of the connector housing with the rear holder. The rib receiving groove which fits may be formed. With such a configuration, the rear holder can be prevented from being tilted and fitted to the connector housing.

  According to the present invention, the lever operating force can be reduced.

A substantially cylindrical rear holder cam pin 32 protruding in the vertical direction is formed from a substantially central position in the width direction of the rear holder 30 in the front of the fitting direction, and is engaged with a rear holder cam groove 44 of the slide lever 40 described later. . With this configuration, the rear holder 30 is fitted into the rear holder fitting recess 29 by the lever operation of the slide lever 40. An engagement rib 33 is formed at the rear end of the outer surface of the rear holder 30 so as to project in a direction orthogonal to the fitting direction (front-rear direction) with the connector body 20. The front end of the rear holder 30 in the fitting direction is formed slightly smaller than the outer surface fitted in the rear holder fitting recess 29 and can enter the housing recess 28. The rear holder 30 is fitted into the rear holder fitting recess 29 in a state where the front end of the rear holder 30 enters the receiving recess 28 and the collective rubber plug 13 is compressed in the front-rear direction, and at the same time, the engaging rib 33 is formed on the outer peripheral edge. It is engaged with the formed rib receiving groove 29A.

  Next, the structure of the slide lever 40 will be described. The slide lever 40 is made of a synthetic resin and has a portal shape in which the base ends of a pair of sliding plates 41 are connected by an operating portion 42 as shown in FIGS. 2 and 5. 41 is slidably held in the lever housing space 23 of the connector body 20. The pair of sliding plates 41 are formed with a connector cam groove 43 and a rear holder cam groove 44 at positions facing each other.

  The connector cam groove 43 has a groove shape penetrating the sliding plate 41 in the vertical direction, and its track extends from the front end of the sliding plate 41 to the connector body 20 on the insertion side with an inclination to the rear. It is formed along the exit direction (left-right direction in FIG. 2), and the tip reaches the approximate center position of the sliding plate 41. The width of the connector cam groove 43 is set such that the connector cam pin 53 provided in the device-side connector 50 can be engaged. The front end of the connector cam groove 43 is a connector inlet recess 43A (corresponding to the inlet of the cam groove) that opens to the front of the sliding plate 41 and to the inner housing 22 side. When it enters, it communicates with the connector cam groove 43. A temporary fastening piece 43B for temporarily locking the connector cam pin 53 inserted through the connector inlet recess 43A is provided at a position near the connector inlet recess 43A of the connector cam groove 43. In the connector cam groove 43, a curved portion inclined in the width direction (front-rear direction) of the sliding plate 41 is an action portion 43C, and the extending direction of the sliding plate 41 on the distal end side (displacement direction of the slide lever 40). ) Extending in parallel to the non-acting portion 43D.

  The rear holder cam groove 44 is a groove penetrating the sliding plate 41 in the vertical direction in the same manner as the connector cam groove 43, and its track is forward from the rear end on the insertion side of the sliding plate 41 into the connector body 20. The tip of the connector cam groove 43 is slightly closer to the insertion side of the connector body 20 than the connector cam groove 43. The width of the rear holder cam groove 44 is set such that the rear holder cam pin 32 provided in the rear holder 30 can be engaged. The front end of the rear holder cam groove 44 is a rear holder inlet recess 44A (corresponding to the inlet of the cam groove) that opens to the rear of the sliding plate 41 and to the inner housing 22 side. When entering, it communicates with the cam groove 44 for the rear holder. A portion of the rear holder cam groove 44 extending in parallel with the extending direction of the sliding plate 41 (displacement direction of the slide lever 40) from the rear holder inlet recess 44A side is defined as a non-acting portion 44B, and the sliding plate is provided at the tip side. A portion extending with an inclination in the width direction of 41 is an action portion 44C.

  The action portion 43C of the connector cam groove 43 and the non-action portion 44B of the rear holder cam groove 44 are arranged to face each other so that the positions in the extending direction of the sliding plate 41 are substantially the same. The non-acting portion 43D of the cam groove 43 and the acting portion 44C of the rear holder cam groove 44 are also arranged to face each other so as to be substantially in the same position. The connector cam pins 53 and the rear holder cam pins 32 are engaged with and guided by the connector cam grooves 43 and the rear holder cam pins 44, respectively. Combined.

Then, the effect | action of this embodiment is demonstrated.
First, as shown in FIG. 1, the slide lever 40 is held at the initial position in the connector main body 20. At this time, the electric wire 11 is connected to the female terminal fitting 12 accommodated in the connector body 20, and the electric wire 11 is inserted into the rubber plug side insertion hole 13 </ b> A of the collective rubber plug 13 and the holder side insertion hole 31 of the rear holder 30. Each is inserted and brought out of the connector 10.

  In order to hold the slide lever 40 in the initial position, first, the sliding plate 41 of the slide lever 40 enters the lever housing space 23 of the connector body 20 from the right side of FIG. In the connector insertion groove 25B provided in the connector 25, the connector inlet recess 43A of the sliding plate 41 is provided. In the rear holder insertion groove 27A provided in the rear holder fitting surface 27, the rear holder inlet recess 44A of the slide plate 41 is provided. Hold to match each other. Then, the connector insertion groove 25B communicates with the connector cam groove 43 via the connector inlet recess 43A of the sliding plate 41, and the rear holder insertion groove 27A passes through the rear holder inlet recess 44A of the sliding plate 41. Thus, the rear holder cam groove 44 is communicated.

  Next, as shown in FIG. 7, the connector cam pin 53 of the device-side connector 50 and the rear holder cam pin 32 of the rear holder 30 are inserted into the connector body 20 with the slide lever 40 held at the initial position. Specifically, the connector cam pin 53 of the device-side connector 50 arranged on the connector fitting surface 25 side is inserted into the connector insertion groove 25 </ b> B, and the temporary stop piece 43 </ b> B provided in the connector cam groove 43 is engaged. The device side connector 50 is pushed in until it is stopped. Similarly, the rear holder cam pin 32 of the rear holder 30 arranged on the rear holder fitting surface 27 side is inserted into the rear holder insertion groove 27A and pushed to a position where it abuts in the rear holder inlet recess 44A. In the state where the slide lever 40 is in the initial position, the device-side connector 50 and the rear holder 30 are only held in the cam grooves 43 and 44 of the slide lever 40 as shown in FIG. That is, the male terminal fitting 52 of the device-side connector 50 and the female terminal fitting 12 of the connector main body 20 are not in contact, and the rear holder 30 does not compress the collective rubber plug 13 accommodated in the accommodating recess 28 in the front-rear direction. It is.

Subsequently, when the operation portion 42 of the slide lever 40 is further pushed in the left direction in FIG. 9, the connector fitting position shown in FIG. 9 is reached. At the connector fitting position, the connector cam pin 53 is located at the boundary between the action portion 43C and the non-action portion 43D of the connector cam groove 43, and the rear holder cam pin 32 is located between the non-action portion 44B and the action portion of the rear holder cam groove 44. It is located at the boundary with 44C. The device-side connector 50 is in a state of being fitted to the connector body 20 as shown in FIG. The hood portion 51 of the device-side connector 50 enters the hood portion fitting space 25A, the male terminal fitting 52 is inserted into the rectangular tube portion 12B of the female terminal fitting 12, and the both terminal fittings 12, 52 are electrically connected. It is connected. The rear holder 30 is not fitted to the connector main body 20, and there is no displacement in the fitting direction from the state in which the slide lever 40 is in the initial position.
By operating the slide lever 40 from the initial position to the connector fitting position, the fitting of the device-side connector 50 is first achieved.

  When the operation portion 42 of the slide lever 40 is further pushed into the connector main body 20 from the connector fitting position, the main fitting position (corresponding to the fitting position) shown in FIG. 11 is reached. In this fitting position, the connector cam pin 53 is located at the tip of the non-acting portion 43D of the connector cam groove 43, and the rear holder cam pin 32 is located at the tip of the acting portion 44C of the rear holder cam groove 44. . As shown in FIG. 12, the device-side connector 50 is still in a fitted state with respect to the connector main body 20 from the connector fitting position, and the rear holder 30 has its front end portion entered into the housing recess 28 and the batch rubber plug 13 is inserted. In a state compressed in the front-rear direction, the rear holder fitting recess 29 is fitted. At this time, as shown in FIG. 13, since the rear holder fitting recess 29 is provided with a rib receiving groove 29A, the engaging rib 33 of the rear holder 30 is fitted into the rib receiving groove 29A so that the rear holder 30 The connector body 20 is fitted without being inclined.

By fitting the rear holder 30 to the connector main body 20, the collective rubber plug 13 is compressed in the front-rear direction as described above. As a result, the inner wall of the rubber plug side insertion hole 27A and the coating of the electric wire 11 are further brought into close contact with each other, and the space between the electric wire 11 and the collective rubber plug 27 is sealed in a watertight manner. In addition, the outer peripheral wall of the collective rubber plug 27 and the inner peripheral wall of the housing recess 26 are further brought into close contact with each other, and the space between the collective rubber plug 27 and the inner housing 22 is also sealed watertight.
Thus, by operating the slide lever 40 from the connector fitting position to the main fitting position, the fitting of the rear holder 30 in addition to the device-side connector 50 is also achieved.

  As described above, according to the present embodiment, the action portion 43C of the connector cam groove 43 corresponds to the non-action portion 43D of the rear holder cam groove 44 with respect to the operation direction of the slide lever 40, and the rear holder cam groove 43 The action part 44C of 44 is formed so as to correspond to the non-action part 43D of the connector cam groove 43. The effect of this configuration will be described in detail. First, when the slide lever 40 is pushed into the connector body 20, the connector cam pin 53 is guided in the action portion 43C of the connector cam groove 43, and only the device-side connector 50 is connected. The connector is displaced in the fitting direction and reaches the connector fitting position shown in FIGS. At the same time, the device-side connector 50 is in a fitted state with respect to the connector body 20. At this time, since the rear holder 30 is held by the non-acting portion 44B of the rear holder cam groove 44 and is not displaced in the fitting direction, only the force necessary for fitting the device-side connector 50 is applied to the slide lever 40. It becomes a state.

  When the slide lever 40 is continuously pushed into the connector body 20, the connector is displaced from the connector fitting position to the main fitting position shown in FIGS. Along with this, the rear holder cam pin 32 of the rear holder 30 is guided in the action portion 44C of the rear holder cam groove 44, and only the rear holder 30 is displaced in the fitting direction to be in a fitted state with the connector main body 20. At this time, the device-side connector 50 is held in a fitted state, and its position is not displaced by the slide lever 40, so that only the force necessary for fitting the rear holder 30 to the slide lever 40 is provided. It takes. Thus, the force required for fitting the device-side connector 50 and the rear holder 30 is alternately applied to the slide lever 40, so that the device-side connector 50 and the rear holder 30 are fitted simultaneously, and both the members 30, 50 are fitted. The maximum value of the operating force required per unit displacement of the slide lever 40 can be reduced as compared with the case where the force required for combining is applied to the slide lever 40 simultaneously.

  Further, when the device-side connector 50 and the rear holder 30 are fitted simultaneously, the lever operating force is reduced by reducing the displacement in the fitting direction of the device-side connector 50 and the rear holder 30 per unit displacement of the slide lever 40. In this case, it is necessary to increase the total length of the cam grooves 43 and 44 that guide the device-side connector 50 and the rear holder 30 in the fitting direction. On the other hand, according to the lever type connector 10 of the present embodiment, the lever operating force can be reduced without increasing the total length of the cam grooves 43 and 44, so that space can be saved. .

  Further, since the rear holder 30 is fitted to the connector body 20 while compressing the collective rubber plug 13, a resistance force acts by the collective rubber plug 13 when the rear holder 30 is fitted. Thereby, the lever operating force required for fitting the rear holder 30 becomes larger than the lever operating force required for fitting the device-side connector 50 to the connector body 20. On the other hand, in the present embodiment, the slide-side lever 40 is urged in the direction of the main fitting position in FIGS. By displacing 30 in the fitting direction, the operability of the lever can be improved and the required lever operating force can be reduced as a whole.

  Further, since the rear holder fitting recess 29 into which the rear holder 30 is fitted is provided with a rib receiving groove 29A, the rear holder 30 is connected to the connector by engaging the engaging rib 33 of the rear holder 30 with the rib receiving groove 29A. Inclining and fitting with respect to the main body 20 can be prevented.
