Description

  The present invention relates to a connector mounting clamp used when mounting a connector for connecting an electric circuit to a vehicle in a vehicle such as an automobile.

  Conventionally, as this type of connector mounting clamp, for example, a configuration disclosed in Patent Document 1 has been proposed. As shown in FIG. 8, the conventional connector mounting clamp 31 is assembled to a bumper bracket 33 having a substantially inverted L-shaped cross section provided on the rear surface of the lower back panel 32 of the vehicle, for example. A connector 35 at the tip of a cord 34 extending from the inside of the vehicle is attached to the clamp 31. When a bumper (not shown) is attached to the rear surface of the lower back panel 32, the connector 37 at the tip of the cord 36 incorporated on the bumper side is connected to the connector 35 on the clamp 31.

  The connector mounting clamp 31 includes a clamp body 38 as shown in FIG. A mounting portion 39 having a substantially T-shaped cross section for mounting the connector 35 protrudes from the mounting seat surface 38 a on the clamp body 38. The connector 35 is provided with a clamp receiving portion 40 that can be engaged with the attachment portion 39. On the surface of the clamp body 38 opposite to the mounting seat surface 38a, a locking leg 41 for locking and fixing to the mounting hole 33a on the bumper bracket 33 is projected.

  When the connector 35 at the tip of the cord 34 is mounted on the bumper bracket 33 using the connector mounting clamp 31, the mounting portion 39 on the clamp body 38 is inserted and engaged with the clamp receiving portion 40 on the connector 35. As a result, the clamp 31 is attached to the connector 35 in advance. In this state, as shown in FIG. 8, the clamp 31 and the connector 35 are inserted from the insertion hole 32 a formed in the lower back panel 32 to the vehicle rear side, and the locking leg 41 on the clamp body 38 is connected to the bumper bracket 33. The clamp 31 and the connector 35 are attached to the rear surface of the bumper bracket 33 by being press-fitted into the mounting hole 33a. When the bumper is attached to the lower back panel 32, the connector 37 at the tip of the cord 36 incorporated on the bumper side is connected to the connector 35 on the clamp 31. Hereinafter, this conventional configuration is referred to as a conventional configuration 1.

JP-A-8-326726

  However, in the conventional connector mounting clamp, the mounting portion 39 for mounting the connector 35 is arranged on the axis of the locking leg portion 41. For this reason, when the connector 31 of the bumper side cord 36 is connected to the connector 35 with the clamp 31 and the connector 35 attached to the bumper bracket 33, the flange portion of the bumper bracket 33 having an approximately inverted L-shaped cross section. May interfere with the work area T1 (see FIG. 9) in which the connector 37 is gripped. Therefore, there is a problem that the connection work of both connectors 35 and 37 cannot be easily performed.

  In order to deal with such a problem, for example, a configuration as shown in FIG. 10 has been proposed. In the connector mounting clamp 31 of this conventional configuration, the clamp body 38 is configured to have a vertically long shape. A mounting seat surface 38 a and a mounting portion 39 for mounting the connector 35 are disposed at a position offset from the axis O of the locking leg portion 41. Thereby, at the time of the connection work of both the connectors 35 and 37, the possibility that the collar part of the bracket 33 may interfere with the work area T1 holding the connector 37 is avoided, and the connection work can be easily performed. Hereinafter, this conventional configuration is referred to as a conventional configuration 2.

  However, in the conventional configuration 2 shown in FIG. 10, the clamp main body 38 is formed in a vertically long shape. Therefore, if the insertion hole 32a (see FIG. 8) of the lower back panel 32 is not made large in diameter, the clamp 31 and the connector 35 are provided. It cannot be inserted through the insertion hole 32a. Further, since the mounting seat surface 38a and the mounting portion 39 of the clamp body 38 are disposed at a position offset from the axial center of the locking leg 41, the clamp 31 is locked by the locking leg when the connectors 35 and 37 are connected. There is also a problem that the connection state of the connectors 35 and 37 tends to be incomplete because the work is difficult to perform by swinging around the axis O of the portion 41.

  The present invention has been made paying attention to such problems existing in the prior art. Its purpose is to allow the clamp body to be easily and securely locked and fixed to the mounting hole of the mounting member with the connector attached, and to connect other connectors to the connector attached to the clamp body. Another object of the present invention is to provide a connector mounting clamp that can be easily performed without interfering with the mounting member.

  In order to achieve the above object, according to the present invention, a mounting portion for mounting a connector for connecting an electric circuit is provided on a mounting seat surface on a clamp body, and the mounting seat surface on the side opposite to the mounting seat surface of the clamp body is provided. In the connector mounting clamp in which a locking leg for locking and fixing to a mounting hole of a mounting member provided on the vehicle is projected on the surface, the mounting seat surface and the mounting portion of the clamp body are It is arranged on a plane inclined with respect to a plane orthogonal to the axis of the leg, and on the opposite side of the clamp leg of the clamp body, the latch leg is moved toward the locking position with respect to the mounting hole. An operation member for performing a pressing operation is provided.

  Therefore, in the connector mounting clamp according to the present invention, when the locking leg of the clamp body is locked to the mounting hole of the mounting member in a state where the connector is mounted on the mounting portion of the clamp body, the clamp body When the upper operating member is pressed, the locking leg is press-fitted into the mounting hole, and the clamp body is fixed on the mounting member. Therefore, even if the mounting seat surface and the mounting portion for mounting the connector are arranged on a plane inclined with respect to the plane orthogonal to the axis of the locking leg, the clamp body is connected to the connector by pressing the operating member. In the attached state, it can be easily and reliably locked and fixed to the attachment hole of the attachment member.

  In addition, since the mounting seat surface and the mounting portion are arranged on a plane inclined with respect to the plane orthogonal to the axis of the locking leg, another connector is connected to the connector mounted on the clamp body. At this time, the possibility that the work area of the connection work interferes with the mounting member can be suppressed. Therefore, the connector connection work can be easily performed without interfering with the mounting member. Further, unlike the conventional configuration 2, the clamp body is not disposed at the position where the mounting seat surface and the mounting portion of the clamp body are offset from the axial center of the locking leg portion. It is also possible to suppress swinging about the axis of the part. In addition, unlike the conventional configuration 2, the clamp body is not formed in a vertically long shape, and it is necessary to guide them onto the mounting member through the insertion hole provided in the vehicle body or the like with the connector attached to the clamp body. There is no need to change the insertion hole to a large diameter.

  In the above-described configuration, the operation member includes a protruding piece protruding in a direction opposite to the locking leg from a portion offset from the axially extended position of the locking leg on the clamp body, and the protrusion It is good to comprise at the front-end | tip of a piece from the press operation part provided so that it might overlap with the extension position of the axial direction of a latching leg part.

The said structure WHEREIN: It is good for the said press operation part to provide the press operation surface arrange | positioned on the plane orthogonal to the axial center of a latching leg part.
The said structure WHEREIN: It is good to provide a slip prevention means in the said press operation surface.

  As described above, according to the present invention, the clamp body can be easily and securely locked and fixed to the mounting hole of the mounting member in a state where the connector is mounted, and the clamp body can be attached to the clamp body. The effect that connection work of other connectors can be easily performed without interfering with the mounting member is exhibited.

An embodiment of a connector mounting clamp embodying the present invention will be described below with reference to FIGS.
As shown in FIGS. 1 and 4, the connector mounting clamp 11 of this embodiment is assembled to a bumper bracket 13 as a mounting member having a substantially inverted L-shaped cross section provided on the rear surface of the lower back panel 12 of the vehicle. A connector 15 at the tip of a cord 14 extending from the inside of the vehicle is attached to the clamp 11. When a bumper (not shown) is attached to the rear surface of the lower back panel 12, the connector 17 at the tip of the cord 16 incorporated on the bumper side is connected to the connector 15 on the clamp 11 and is provided on the bumper (not shown). The electrical circuit of the electrical equipment to be connected is connected.

  As shown in FIGS. 2 and 4, the connector mounting clamp 11 is made of a synthetic resin, and is provided with a flat clamp body 18. The clamp body 18 is fixed to a mounting hole 13a formed in the bumper bracket 13 on the lower surface of the substrate 18a having a substantially square plate shape, that is, the surface opposite to the mounting seat surface 18g of the clamp body 18. The locking leg 21 is projected. A stabilizer 21 a is formed on the outer periphery of the base of the locking leg 21 so as to be elastically contactable with the rear surface (surface) of the bumper bracket 13. Further, as shown in FIG. 6, a pair of elastic locking claws 21b project from the side surfaces 180 degrees opposite to each other on the distal end side from the stabilizer 21a on the outer periphery of the base portion of the locking leg portion 21. . In FIG. 2, only one locking claw 21b is shown.

  On the other hand, as shown in FIGS. 3 (a) and 3 (b), the board 18a has side plates 18b rising from both end edges positioned in a direction orthogonal to the connecting direction of the connector 15 described later. A mounting portion 19 is provided on the upper surface of the substrate 18a. Since the structure of the attachment part 19 is well-known, it is demonstrated easily. The attachment portion 19 includes a pair of engaging blade pieces 18c that are spaced apart from each other in a direction orthogonal to the connecting direction, and an engaging piece 18d that connects the two engaging blade pieces 18c so as to form an approximately H shape, A pair of side walls 18e that connect the inner edge portion in the connecting direction and the upper surface of the substrate 18a are provided from the engaging pieces 18d of the both engaging blade pieces 18c. FIG. 3B is a perspective view of the main part around the mounting seat surface of the clamp body when both the engagement wing pieces 18c and the engagement pieces 18d are removed.

  A misinsertion prevention wall 18f is provided at one end of each side wall 18e to close the space between the engagement blade piece 18c and the substrate 18a. Further, the engagement piece 18d is formed at a position near the end on the opposite side to the erroneous insertion prevention wall 18f of both engagement blade pieces 18c.

  In the present embodiment, the upper surface of the substrate 18a covered with the both engaging blade pieces 18c is the mounting seat surface 18g. Further, the mounting seat surface 18 g and the mounting portion 19 of the clamp body 18 are configured to be disposed on a plane inclined with respect to a plane orthogonal to the axis of the locking leg portion 21.

  On the other hand, the connector 15 is provided with a known clamp receiving portion 20 that can be engaged with the mounting portion 19. As shown in FIG. 4, the clamp receiving part 20 has a pair of L-shaped protrusions facing each other.

  As shown in FIGS. 2 and 4, on the part of the clamp body 18 opposite to the locking leg 21, the locking leg 21 is pressed toward the locking position with respect to the mounting hole 13 a of the bumper bracket 13. An operating member 22 for projecting is provided. As shown in FIG. 5, the operating member 22 is a protruding piece 23 that protrudes in a direction opposite to the locking leg 21 from a portion offset from the axially extending position P1 of the locking leg 21 on the clamp body 18. And an extension position P1 in the axial direction of the locking leg 21 and a pressing operation portion 24 formed so as to wrap a predetermined amount L1 at the tip of the protruding piece 23.

  As shown in FIG. 5, the pressing operation portion 24 of the operation member 22 is formed with a pressing operation surface 24 a disposed on a plane orthogonal to the axis of the locking leg portion 21. The pressing operation surface 24a is provided with an anti-slip portion 25 as anti-slip means. That is, the non-slip portion 25 is configured by forming the concave portion 25a and the convex portion 25b at the base end portion of the pressing operation surface 24a and making the convex portion 25b higher than the pressing operation surface 24a by a predetermined amount L2. .

(Operation of the embodiment)
Next, a method of using the connector mounting clamp configured as described above will be described.
When the connector 15 at the tip of the vehicle-side cord 14 is mounted on the bumper bracket 13 using the connector mounting clamp 11, first, as shown in FIG. 4, a pair of clamp receiving portions 20 on the connector 15 is provided. The clamp 11 is attached to the connector 15 in advance by inserting and engaging between the engaging wing pieces 18c constituting the attachment portion 19 on the clamp body 18 and the attachment seat surface 18g with respect to the protrusion. In this state, as shown in FIG. 1, the clamp 11 and the connector 15 are inserted from the insertion hole 12 a formed in the lower back panel 12 to the vehicle rear side, and are arranged at the rear position of the bumper bracket 13. In this case, since the clamp body 18 is not formed vertically long, the insertion work of the clamp 11 and the connector 15 into the insertion hole 12a can be easily performed without increasing the diameter of the insertion hole 12a of the lower back panel 12. .

  Thereafter, as shown in FIG. 4, the locking leg portion 21 of the clamp body 18 is disposed corresponding to the mounting hole 13 a of the bumper bracket 13, and the pressing operation surface 24 a on the pressing operation portion 24 of the operation member 22 is pressed. . Then, when the locking leg 21 is press-fitted into the mounting hole 13a against the elasticity of the locking claw 21b, the pair of locking claw 21b is locked to the rear surface side periphery of the mounting hole 13a as shown in FIG. At the same time, the stabilizer 21 a is brought into contact with the peripheral edge on the surface side of the mounting hole 13 a, and the clamp body 18 is locked and fixed on the bumper bracket 13. In this case, since the locking leg 21 is press-fitted into the mounting hole 13 a by pressing the operating member 22, the mounting seat surface 18 g and the mounting part 19 of the clamp body 18 are orthogonal to the axis of the locking leg 21. Even if it is arranged on a plane that is inclined with respect to the plane, the locking leg 21 can be easily and surely fitted and locked by efficiently applying a pressing force to the mounting hole 13a. Moreover, since the anti-slip | skid part 25 is provided in the press operation surface 24a of the press operation part 24, there exists no possibility that a slip may arise at the time of press operation of the press operation surface 24a.

  When a bumper (not shown) is attached to the lower back panel 12, the connector 15 on the clamp 11 is attached to the bumper bracket 13 in advance, and the cord 16 incorporated on the bumper side with respect to the connector 15. The electrical circuit is connected by performing the connection work while holding the connector 17 at the tip. At this time, the mounting seat surface 18g and the mounting portion 19 of the clamp body 18 are arranged on a plane inclined with respect to a plane perpendicular to the axis of the locking leg portion 21, and as shown in FIG. The upper part of the connector 15 is open. For this reason, there is no possibility that the work area T1 interferes with the flange portion of the bumper bracket 13 when the bumper side connector 17 is connected to the vehicle side connector 15. In addition, since the mounting seat surface 18g and the mounting portion 19 of the clamp body 18 are not disposed at a position offset from the axis of the locking leg portion 21, the clamp body 18 is not locked when the connectors 15 and 17 are connected. There is no possibility of swinging around the axis of the portion 21.

Therefore, according to this embodiment, the following effects can be obtained.
(1) In this connector mounting clamp, a mounting portion 19 for mounting a connector 15 for connecting an electric circuit is provided on a mounting seat surface 18 g on the clamp body 18. On the surface of the clamp body 18 opposite to the mounting seat surface 18g, a locking leg portion 21 for locking and fixing to a mounting hole 13a of a bumper bracket 13 as a mounting member provided on the vehicle is projected. . The mounting seat surface 18g and the mounting portion 19 of the clamp body 18 are arranged on a plane inclined with respect to a plane orthogonal to the axis of the locking leg 21. An operation member 22 for pressing the locking leg 21 toward the locking position with respect to the mounting hole 13a is provided on the portion of the clamp body 18 opposite to the locking leg 21.

  Therefore, when the locking leg portion 21 of the clamp body 18 is locked and fixed to the mounting hole 13a of the bumper bracket 13 with the connector 15 attached to the mounting portion 19 of the clamp body 18, When the operation member 22 is pressed, the locking leg 21 is press-fitted into the mounting hole 13 a and the clamp body 18 is fixed on the bumper bracket 13. Therefore, even if the mounting seat surface 18g and the mounting portion 19 for mounting the connector 15 are arranged on a plane inclined with respect to the plane orthogonal to the axis of the locking leg portion 21, the pressing operation of the operating member 22 The clamp body 18 can be easily and reliably locked and fixed to the mounting hole 13a of the bumper bracket 13 with the connector 15 mounted.

  In addition, since the mounting seat surface 18g and the mounting portion 19 are arranged on a plane inclined with respect to a plane orthogonal to the axis of the locking leg portion 21, the vehicle-side connector 15 attached to the clamp body 18 is provided. On the other hand, when connecting the bumper-side connector 17, it is possible to suppress the possibility that the work area T <b> 1 of the connection work interferes with the bumper bracket 13. Therefore, the connection work of the connectors 15 and 17 can be easily performed without interfering with the bumper bracket 13.

  Further, unlike the conventional configuration, the mounting seat surface 18g and the mounting portion 19 of the clamp body 18 are not arranged at a position offset from the axis of the locking leg portion 21, so that when the connectors 15 and 17 are connected, It is also possible to suppress the clamp body 18 from swinging around the axis of the locking leg 21. In addition, since the clamp body 18 is not formed vertically long as in the conventional configuration, the bumper bracket is inserted through the insertion hole 12a formed in the lower back panel 12 of the vehicle body with the connector 15 attached to the clamp body 18. In the case of guiding to 13, the insertion hole 12a does not need to be changed to a large diameter.

  (2) In this connector mounting clamp, the operation member 22 protrudes in a direction opposite to the locking leg 21 from a portion offset on the clamp body 18 from the extended position of the locking leg 21 in the axial direction. And a pressing operation portion 24 provided at the tip of the protruding piece 23 so as to overlap the extended position of the locking leg 21 in the axial direction. For this reason, the protruding piece 23 of the operation member 22 can be protruded on the clamp body 18 without interfering with the connector 15 attached to the attachment portion 19. Further, since the pressing operation portion 24 at the tip of the operation member 22 is arranged so as to wrap around the extended position of the locking leg portion 21 in the axial direction, the pressing operation force applied to the pressing operation portion 24 is applied to the locking leg portion 21. Can be made to act efficiently. Therefore, the locking leg 21 can be more securely locked and fixed to the mounting hole 13a of the bumper bracket 13, and the locking and fixing state of the locking leg 21 with respect to the mounting hole 13a becomes incomplete. Can be prevented.

  (3) In this connector mounting clamp, the pressing operation portion 24 is provided with a pressing operation surface 24 a disposed on a plane orthogonal to the axis of the locking leg portion 21. For this reason, the pressing operation force with respect to the pressing operation surface 24 a of the pressing operation unit 24 can be applied to the locking leg 21 more efficiently.

  (4) In this connector mounting clamp, an anti-slip portion 25 as anti-slip means is provided on the pressing operation surface 24a. For this reason, when pressing the pressing operation surface 24a of the pressing operation unit 24, it is possible to prevent the possibility of slipping.
