Description

Technical Field

[0001] The utility model relates to the technical field of wire harness fixing clamps, in particular to a wire harness fixing clamp. Background Art

[0002] In many fields such as electronic product manufacturing and automobile industry production, a large number of wire harnesses are involved, so the wire harnesses need to be fixed and managed. The main wire harness fixing methods currently used include bundling and adhesion.

[0003] Among them, the bundling type is mainly fixed by cable ties. Although this method is simple, it is difficult to determine the tightening force of the cable ties. If it is too loose, it may cause the wire harness to be loose, and if it is too tight, it may cause the wire harness to be bent. Long-term bending may cause damage to the internal lines of the wire harness. The adhesion type uses tape or Velcro to fix the wire harness. Although this method can effectively control the tightening force of the wire harness, it is also easily affected by environmental factors (such as temperature, humidity, etc.). The tape or Velcro may age or become less sticky, which may make it unable to restrain the wire harness. Utility Model Content

[0004] The utility model provides a wire harness fixing clip to solve the problem that the wire harness is easy to bend or age in the prior art wire harness fixing method.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is to provide a wire harness fixing clamp, which includes: a base, a pressure cover and a fixing seat.

[0006] The base includes a first limiting member and a second limiting member, wherein the first limiting member and the second limiting member are arranged at intervals along a first direction and form a restraining groove for accommodating a wiring harness.

[0007] One end of the pressure cover is rotatably connected to the first limit member, and the other end can be engaged with the second limit member, wherein, when the pressure cover is engaged with the second limit member, the pressure cover forms a vertical limiting space with the constraint groove along the second direction, which is used to limit the wiring harness along the second direction; the fixed seat is located on the side of the base away from the first limit member and the second limit member along the second direction.

[0008] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0009] By providing a base and a first limiting member and a second limiting member protruding from both ends of the base, a restraining groove for accommodating the wiring harness can be formed on the base, that is, a restraining force is formed toward the inside of the restraining groove along a first direction.

[0010] Among them, one end of the pressure cover is rotatably connected to the first limit member, and the other end can be clamped with the second limit member, so that the pressure cover can be rotationally opened and closed compared to the base. When the pressure cover is clamped with the second limit member, it can form a vertical limiting space with the constraint groove along the second direction, that is, a balanced downward pressure is formed between the first limit member and the second limit member, so that it can constrain the wiring harness in the vertical direction.

[0011] The vertical and horizontal restraints mentioned above can effectively fix and manage the wire harness while avoiding damage to the wire harness (such as bending of the wire harness). The mechanical connection between the gland and the base will not fail due to aging of the tape, and can effectively fix the wire harness for a long time. In addition, a fixing seat is provided at the bottom of the base to fix the wire harness at a set position, realizing accurate positioning and management of the wire harness.

[0012] In some embodiments, an elastic band is provided on the inner side of the pressure cover, and the two ends of the elastic band are respectively connected to the two end sides of the pressure cover, so that when the pressure cover is buckled with the second limiting piece, the elastic band can form a vertical limiting space with the constraint groove, which is used to limit the wiring harness along the second direction.

[0013] By adopting the above technical solution, an elastic band is arranged to constrain the wire harness in the second direction, so that the pressure on the wire harness can be adjusted. When the elastic band covers the constraint groove and forms a vertical limit wire harness, the elastic band can produce a certain degree of deformation, thereby forming a plurality of protrusions according to the wire harness, thereby constraining each wire harness to a certain degree.

[0014] In some embodiments, the gland is arc-shaped, wherein the elastic band is located inside the arc of the gland. The gland is arranged in an arc shape so that there is ample space inside the gland, that is, when the elastic band limits the wiring harness, the elastic band can have sufficient deformation space.

[0015] In some embodiments, the base is further provided with an elastic member, which is located along the first direction on the side of the first limiting member toward the second limiting member and / or on the side of the second limiting member toward the first limiting member, and forms a lateral limiting space for limiting the wiring harness along the first direction.

[0016] By adopting the above technical solution, elastic parts are added on both ends of the constraint groove, so that when the total width of multiple wire harnesses is smaller than the width of the constraint groove, the elastic parts can abut against the wire harnesses along the first direction and provide lateral constraint force to the wire harnesses, thereby adjusting the number of wire harnesses placed.

[0017] In some embodiments, a non-slip pad is further provided on the top of the base along the second direction, and the non-slip pad is located in the restraining groove.

[0018] By adopting the above technical solution, an anti-skid pad is added to enhance the friction of the constraint groove on the wiring harness to prevent the wiring harness from falling out.

[0019] In some embodiments, the fixing seat is provided with a connecting portion and a spiral portion in sequence along the second direction, the connecting portion is connected to the bottom of the base and is located in the middle of the base along the first direction; the spiral portion is provided with an external thread.

[0020] By adopting the above technical solution, a thread is set at the bottom of the fixing seat, so that the wire harness fixing clamp can be spirally matched with the corresponding mounting hole on the mounting plane (wire harness fixing plane), and this method can achieve stable installation of the wire harness fixing clamp without unnecessary accessories.

[0021] In some embodiments, the fixing seat further comprises a dome portion, the dome portion being located between the connecting portion and the spiral portion along the second direction. The dome portion is added to the fixing seat to unify the depth of the wire harness fixing clip embedded in the mounting plane, and the dome portion can also enhance the stability of the fixing seat.

[0022] In some embodiments, the gland and the second stopper have a first hook at one end thereof, the first hook being bent along the first direction toward the inside of the gland; the second stopper has a second hook capable of cooperating with the first hook, wherein the second hook is bent along the first direction toward a side away from the accommodation groove. The cooperation between the first hook and the second hook facilitates the rapid fastening of the gland and the second stopper, and the connection between them is stable.

[0023] In some embodiments, the base and the fixing seat are integrally injection molded.

[0024] By adopting the above technical solution, the one-piece injection-molded base and fixing seat can improve the stability of the wire harness fixing frame, provide sufficient structural strength and stability for the wire harness fixing clamp, and the hard plastic has a certain degree of deformation, which is convenient for restraining the wire harness.

[0025] In some embodiments, the wire harness fixing clamp further includes a mounting piece having a mounting hole, wherein the spiral portion of the fixing seat is embedded in the mounting piece along the mounting hole, and the dome portion of the fixing seat is located at an upper end of the mounting piece along the second direction.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0034] In order to facilitate the subsequent description, before describing the specific structure of the wiring harness fixing clip, this application first combines Figure 3 A first direction (X) and a second direction (Z) are defined. The first direction is the horizontal direction of the harness fixing clamp when it is normally placed, such as the X direction; the second direction is the height direction of the harness fixing clamp when it is normally placed, such as the Z direction; in this application, the first direction (X) and the second direction (Z) are perpendicular to each other.

Figure 1 ; Figure 2 The three-dimensional structure diagram of an embodiment of a wire harness fixing clip provided by the present application is shown in FIG. Figure 2 .

[0036] In some embodiments, the wire harness fixing clamp includes: a base 10 , a pressure cover 20 and a fixing base 30 .

[0037] The base 10 includes a first stopper 11 and a second stopper 12 . The first stopper 11 and the second stopper 12 are spaced apart along a first direction and form a restraining groove 13 for accommodating the wire harness 50 ′.

[0038] One end of the pressure cover 20 is rotatably connected to the first limit member 11, and the other end can be clamped with the second limit member 12, wherein, when the pressure cover 20 is clamped with the second limit member 12, the pressure cover 20 forms a vertical limiting space with the constraint groove 13 along the second direction, which is used to limit the wiring harness 50' along the second direction; the fixed seat 30 is located on the side of the base 10 away from the first limit member 11 and the second limit member 12 along the second direction.

[0039] In the embodiment of the present application, by providing the base 10 and the first stopper 11 and the second stopper 12 protruding at both ends of the base 10, a restraining groove 13 for accommodating the wire harness 50' can be formed on the base 10, that is, a restraining force is formed toward the inner side of the restraining groove 13 along the first direction. Figure 2 As shown, eight wire harnesses 50' are arranged in the restraining groove 13, and the edges of the plurality of wire harnesses 50' are respectively in contact with the first stopper 11 and the second stopper 12. The present application does not limit the width of the restraining groove 13, and it can be designed according to the specifications of the actual wire harness 50', so that the wire harness 50' can be closely attached and confined in the restraining groove 13.

[0040] Among them, one end of the gland 20 is rotatably connected to the first limiter 11, and the other end can be engaged with the second limiter 12, so that the gland 20 can be opened and closed in a rotational manner compared to the base 10. When the gland 20 is engaged with the second limiter 12, a vertical limit space can be formed with the constraint groove 13 along the second direction, that is, a balanced downward pressure is formed between the first limiter 11 and the second limiter 12, so that the wiring harness 50' is constrained in the vertical direction. Exemplarily, the gland 20 is pressed flatly on the constraint groove 13.

In addition, the mechanical connection between the gland 20 and the base 10 will not fail due to aging of the adhesive tape, and the wire harness 50' can be effectively fixed for a long time.

[0042] In some embodiments, an elastic band 21 is provided on the inner side of the pressure cover 20, and the two ends of the elastic band 21 are respectively connected to the two end sides of the pressure cover 20, so that when the pressure cover 20 is buckled with the second limiting member 12, the elastic band 21 can form a vertical limiting space with the constraint groove 13, which is used to limit the wiring harness 50' along the second direction.

[0043] In the embodiment of the present application, an elastic band 21 is provided to constrain the wire harness 50' in the second direction, so that the pressure on the wire harness 50' can be adjusted. Figure 2 As shown, when the elastic band covers the constraint groove 13 and forms the vertical limiting wire harness 50', the elastic band 21 can produce a certain degree of deformation, thereby forming a plurality of protrusions according to the wire harness 50', and each wire harness 50' has a certain degree of constraint.

[0044] Exemplarily, the gland 20 is in an arc shape, wherein the elastic band 21 is located inside the arc of the gland 20. The gland 20 is set in an arc shape so that there is ample space inside the gland 20, that is, when the elastic band 21 limits the wiring harness 50', the elastic band 21 can have sufficient deformation space. The elastic band 21 refers to a belt-shaped product made of a material with good elasticity, such as a rubber elastic band.

[0047] In the embodiment of the present application, elastic members 14 are added to both ends of the constraint groove 13, so that when the total width of the plurality of wire harnesses 50' is smaller than the width of the constraint groove 13, the elastic member 14 can abut against the wire harnesses 50' along the first direction and provide a lateral constraint force to the wire harnesses 50', thereby adjusting the number of wire harnesses 50' placed. Exemplarily, the elastic member 14 can be arranged on either side or both sides of the constraint groove 13. The elastic member 14 can be a spring or rubber.
