Description

  The present invention relates to a connector mounting structure in which a connector is mounted on a mounting member so as to be movable.

  As this type of conventional connector mounting structure, for example, one disclosed in Patent Document 1 has been proposed.

  As shown in FIGS. 14 and 15, this connector mounting structure includes a mounting member 50 in which a connector mounting hole 51 is opened, and a connector 60 that is mounted in a state of being inserted into the connector mounting hole 51. The connector mounting hole 51 is provided slightly larger than the upper, lower, left and right outer diameter dimensions of the connector housing 61. A pair of notches 52 are provided at the peripheral positions of the connector mounting hole 51 in the vertical and horizontal directions. The width dimension of each notch 52 is set larger than the thickness of the protective rib 63 described below.

  The connector 60 has a connector housing 61 and a number of terminals (not shown) accommodated in the connector housing 61. Locking arm portions 62 protrude from the upper, lower, left and right outer wall surfaces of the connector housing 61, respectively. A pair of protective ribs 63 project from the left and right positions of each locking arm 62. A pair of an insertion stopper wall 64 and a retaining elastic wall 65 are provided on the upper and lower surfaces of the connector housing 61 and on the left and right positions of the locking arm portion 62, respectively.

  Next, the attachment work of the connector 60 will be described. The connector 60 is inserted into the connector mounting hole 51 of the mounting member 50. Then, each locking arm portion 62 and each retaining elastic wall 65 of the connector 60 are elastically deformed, and insertion of the connector 60 is allowed. When the insertion stopper wall 64 of the connector 60 is inserted to a position where it hits the periphery of the connector mounting hole 51, each locking arm portion 62 and each retaining elastic wall 65 are elastically restored, and each retaining arm portion 62 and each retaining arm wall 62 are removed. The stop elastic wall 65 is locked to the periphery of the connector mounting hole 51. This completes the mounting operation of the connector 60.

  In the connector 60, each locking arm 62 is locked to the mounting member 50, and the mounting member 50 is sandwiched between the insertion stopper wall 64 and the retaining elastic wall 65 so that it does not fall off from the mounting member 50. It is attached. The connector 60 is mounted in the connector mounting hole 51 in a state where it receives an elastic restoring force from each of the locking arm portions 62 in the vertical and horizontal positions. Accordingly, the connector 60 can be shifted in the vertical and horizontal directions within the connector mounting hole 51 within a range in which each locking arm 62 can be elastically deformed. Thereby, even if there is a position shift with the mating connector, this can be absorbed and the connector can be fitted.

JP-A-9-45433

  In the conventional connector mounting structure, since the mounting is completed simply by inserting the connector 60 into the connector mounting hole 51 of the mounting member 50, the mounting workability is good.

  However, even after the connector 60 is attached to the attachment member 50, the elastic restoring force of each locking arm portion 62 always acts, so that the locking force of each locking arm portion 62 becomes weak after many years of use. Further, since the retaining elastic wall 65 is also a member that is elastically deformed, it is easily deformed by the action of an external force. For these reasons, there is a problem that the connector 60 may easily fall off the mounting member 50 due to long-term use.

  Accordingly, the present invention has been made to solve the above-described problems, and provides a connector mounting structure in which the connector mounting workability is good and the connector is not easily dropped from the mounting member even after many years of use. With the goal.

  According to the present invention, the attachment member is provided with a connector attachment hole having a size larger than that of the connector, and the connector attachment hole is provided so as to be capable of being inserted from an insertion / removal position which is a predetermined position to the attachment position of the connector, The connector inserted to the mounting position of the connector mounting hole is provided so as to be slidable in a direction orthogonal to the connector insertion direction and in a direction orthogonal to each other, and locked by sliding to a position opposite to the insertion / removal position of the connector. And a locking means for preventing sliding to the insertion / removal position is provided, and the connector slides in a direction orthogonal to the connector insertion direction and in a direction orthogonal to each other within a range not subject to slide restriction by the locking means. A connector mounting structure characterized by being provided freely.

  The locking means is a locking rod provided on the mounting member and a locking claw provided on the connector, and the locking claw slides in a direction away from the insertion / removal position of the connector. Thus, it is preferable that the locking rod is overcome by elastic deformation, and at the position where the locking rod is overcome, it is elastically restored and positioned at the locking position.

  The mounting member is provided with a pair of slide rail walls protruding to the connector insertion side and the connector outlet side of the connector mounting hole, and the slide rail wall on the connector insertion side and the slide rail wall on the connector protruding side Notches are provided so as not to overlap each other when viewed from the insertion direction, and the connector is provided with a slide protrusion wall that can enter between a pair of slide rail walls, and the slide protrusion wall is inserted into the connector. It is preferable to be provided at a position corresponding to the notch portion of the slide rail wall on the connector insertion side in the detached position.

  According to the present invention, when the connector is inserted into the connector mounting hole of the mounting member and then slid thereafter, the mounting is completed. The locking means only needs to have a structure that can restrict only the sliding of the connector to the insertion / removal position after being locked to the mounting member. There is no, and the locking force does not become weak by long-term use. From the above, the mounting workability of the connector is good, and the connector does not easily fall off the mounting member even after many years of use.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  1 to 13 show an embodiment of the present invention. As shown in FIGS. 1 to 7, the connector mounting structure includes a mounting member 1 in which a connector mounting hole 2 is opened, and a connector 10 that is mounted in a state of being inserted into the connector mounting hole 2.

  The mounting member 1 is, for example, a vehicle body panel. The connector mounting hole 2 corresponds to the shape of the connector 10 and has a substantially rectangular shape. The dimensions (height dimension: h1, width dimension: w1) of the connector mounting hole 2 are respectively set larger than the upper, lower, left and right outer diameter dimensions (height dimension: h2, width dimension: w2) of the connector housing 11. (See FIG. 4).

  A pair of slide rail walls 3 and 4 project from each position of the upper surface and the lower surface of the connector mounting hole 2 at intervals in the connector insertion direction (A arrow direction). A slide groove 5 is formed between the pair of slide rail walls 3 and 4.

  The slide rail wall 3 on the connector insertion side and the slide rail wall 4 on the connector protrusion side are provided with notches 3a and 4a so as not to overlap each other when viewed from the connector insertion direction (A arrow direction).

  A locking rod 6 extending in the vertical direction is provided near one side end of the connector mounting hole 2.

  The connector 10 has a connector housing 11 and a number of terminals (not shown) accommodated in the connector housing 11. An electric wire W is connected to each terminal.

  Slide protrusion walls 12 are provided on the upper and lower surfaces of the connector housing 11. The upper and lower slide projecting walls 12 are provided at a position corresponding to the notch 3a of the slide rail wall 3 on the connector insertion side at the connector insertion / removal position. Slide rail avoiding grooves 13 are respectively formed on the upper and lower surfaces of the connector housing 11 at positions corresponding to the slide rail walls 3. The slide rail avoiding groove 13 is for avoiding interference with the slide rail wall 4 on the connector protruding side when the connector 10 is inserted into the connector mounting hole 2.

  When the connector 10 is inserted up to the mounting position of the connector mounting hole 2, it can slide in the left-right direction H and the vertical direction V. At a position other than the connector insertion / removal position, at least a part of the slide projection wall 12 of the connector 10 is between the slide rail wall 3 on the connector insertion side and the slide rail wall 4 on the connector projection side. It cannot overlap and come out of the connector mounting hole 2.

  The connector housing 11 is provided with a locking claw 14. The locking claw 14 and the locking rod 6 constitute locking means 7. The connector 10 is restricted from moving to the connector insertion / removal position when the locking claw 14 is locked to the locking rod 6. However, within the range not subject to the slide restriction by the locking means 7, the slide protruding wall 12 of the connector 10 can freely slide in the left-right direction H while being guided by the pair of slide rail walls 3, 4 of the connector mounting hole 2. The locking means 7 allows the connector 10 to slide in the vertical direction V. Within the range of the connector mounting hole 2, the sliding projection wall 12 of the connector 10 is a pair of slide rail walls 3 and 4 of the connector mounting hole 2. It can slide freely in the vertical direction V while being guided.

  Next, a procedure for attaching the connector 10 will be described. As shown in FIG. 8, the connector 10 is aligned with the connector mounting hole 2 at the connector insertion / removal position. Then, as shown in FIG. 9, the connector 10 is inserted in the connector insertion direction A into the connector mounting hole 2. As shown in FIG. 10, the connector 10 is inserted to a position where the slide protruding wall 12 of the connector 10 abuts against the slide rail wall 4 on the connector protruding side. This position is the mounting position of the connector 10.

  Next, as shown in FIG. 10, the connector 10 is slid in a direction orthogonal to the connector insertion direction A, specifically, in the left-right direction H. The connector 10 slides while being guided by the pair of slide rail walls 3 and 4, and the locking claw 14 hits the locking rod 6. When the connector 10 is further slid from this state, the locking claw 14 is elastically deformed and gets over the locking rod 6. As shown in FIG. 11, when the locking claw 14 slides to a position where it completely climbs over the locking rod 6, the locking claw 14 is elastically deformed back to its original position. This completes the mounting operation of the connector 10.

  Since the connector 10 cannot be slid to the connector insertion / removal position by the locking claw 14 and the locking rod 6, the connector 10 is mounted in the connector mounting hole 2.

  The connector 10 attached to the connector attachment hole 2 slides in the left and right direction H and the up and down direction V within the connector attachment hole 2 within a range not subject to slide restriction by the engagement means 7 of the engagement claw 14 and the engagement rod 6. I can move.

  Specifically, with respect to the left-right direction H, the position where the tip of the locking claw 14 abuts against the inner surface of the connector mounting hole 2 (the position shown in FIG. 12A) and the locking claw 14 are locked to the locking rod 6. It is possible to slide between the position where it is locked (the position shown in FIG. 12C). FIG. 12B shows an intermediate position of the slide movement in the left-right direction H. With respect to the vertical direction V, the position at which the slide projection wall 12 on the lower surface of the connector 10 abuts against the bottom surface of the connector mounting hole 2 (position in FIG. 13A) and the slide projection wall 12 on the upper surface of the connector 10 are attached to the connector. It is possible to slide between the position where it hits the upper surface of the hole 2 (the position shown in FIG. 13C). FIG. 13B shows an intermediate position of the slide movement in the vertical direction V.

  Thus, since the connector 10 can be shifted in the vertical and horizontal directions within the connector mounting hole 2, even if there is a positional deviation with respect to the mating connector, this can be absorbed and the connector can be fitted.

  As described above, when the connector 10 is inserted into the connector mounting hole 2 of the mounting member 1 and slid thereafter, the mounting is completed. After the locking means 7 is locked to the mounting member 1, as long as it has a structure that can restrict only the sliding of the connector 10 to the insertion / removal position as in the embodiment, the elastic restoring force is applied after the mounting is completed. It is not necessary to have a structure that always acts, and the locking force does not become weaker after many years of use. As described above, the mounting workability of the connector 10 is good, and the connector 10 can be structured so as not to easily fall off the mounting member 1 even when used for many years.

  Moreover, since the connector 10 can move within the connector mounting hole 2 of the mounting member 1, the external force applied to the connector 10 can be absorbed by sliding movement, and the connector 10 is strong against the external force.

  The locking means 7 includes a locking rod 6 provided on the attachment member 1 and a locking claw 14 provided on the connector 10. Therefore, the locking means 7 has a simple structure. In this embodiment, the locking means 7 is constituted by the locking rod 6 and the locking claw 14, but any means that can prevent the connector 10 from moving to the insertion / removal position may be used. The locking means 7 may be configured by providing the mounting member 1 with a locking claw 14 and the connector 10 with a locking rod 6, contrary to this embodiment.

  The mounting member 1 is provided with a pair of slide rail walls 3 and 4 projecting to the connector insertion side and the connector outlet side of the connector mounting hole 2, and the slide rail wall 3 on the connector insertion side and the slide rail wall 4 on the connector projection side are The cutout portions 3a and 4a are provided so as not to overlap each other when viewed from the connector insertion direction, the connector 10 is provided with a slide projection wall 12, and the slide projection wall 12 is in the connector insertion / removal position so that the connector is inserted. It is provided at a position corresponding to the notch 3 a of the slide rail wall 3 on the side. Therefore, the connector mounting hole 2 can be inserted up to the mounting position of the connector 10 at the connector insertion / removal position, and the connector 10 can be reliably prevented from dropping at a position other than the insertion / removal position of the connector 10.
