Description

Technical Field

[0001] The utility model relates to the technical field of wiring harness fixing connectors, in particular to a fixing seat assembled with a stud. Background Art

[0002] Currently, when installing multiple wiring harnesses inside a car, a structure for fixing cable ties needs to be set on the car body. Usually, multiple studs are welded at the positions where the wiring harnesses need to be fixed on the car body. When installing the wiring harnesses, the fixing seats are clamped on the studs and then the cable ties are used to connect the wiring harnesses to the fixing seats.

[0003] Due to the large number of studs during the installation process, the operator needs to perform multiple repetitive actions to press the fixing seat to insert the studs into the fixing seat, which is labor-intensive.

[0004] Typically, the mounting base is a tubular structure with open ends. To ensure the mounting base's strength, the tubular structure is typically short, and the upper end of the stud often protrudes from the mounting base during installation. This type of mounting base often causes the upper end of the stud to contact the operator during installation, potentially causing injury. Furthermore, after the wiring harness is installed, the stud protruding from the mounting base can also cause damage to the harness. Utility Model Content

[0005] In response to the shortcomings of the above-mentioned existing production technology, the applicant provides a fixing base that is assembled with a stud, thereby reducing the labor intensity of the operator when installing the fixing base, avoiding injury to the operator by the stud during installation, and avoiding damage to the wiring harness connected to the fixing base by the stud during use.

[0011] A fixing portion, provided at the other end of the main body structure, for setting a cable tie;

[0012] When the stud is inserted, the lock head flips toward the inner wall; when the teeth on the lock head are embedded in the bottom of the thread from the side of the stud, the fixing seat is connected to the stud; when the stud is pulled out, the lock head flips toward the center of the main body structure, and multiple teeth cooperate with the thread of the stud to limit the fixing seat.

[0013] As a further improvement of the above technical solution:

[0014] The outer wall of the main body structure is provided with a reinforcement ring, one side of the fixing portion is connected to the outer wall of the main body structure, and the other side of the fixing portion is connected to the reinforcement ring.

[0015] The reinforcement ring is a sheet-like structure.

[0016] The cable tie is detachably connected to the fixing portion.

[0017] The inner wall of the main body structure is provided with a plurality of reinforcing ribs, the length direction of the reinforcing ribs is consistent with the length direction of the main body structure, and each reinforcing rib is provided between two adjacent lock heads.

[0018] The number of locks and reinforcement ribs is four.

[0019] The cross section of the main body structure is square, and the four lock heads are respectively located at the four inner corners of the square.

[0020] The connection positions of the multiple lock heads and the main body structure are located at different cross sections of the main body structure, and the two lock heads arranged opposite to each other are located at the same cross section position.

[0021] It also includes an elastic connecting portion, through which the lock head is elastically connected to the main body structure, and the cross-section of the elastic connecting portion is smaller than the cross-section of the lock head.

[0022] A limiting portion is provided on the lock head, and the limiting portion is located between the plurality of teeth and the end surface of the main body structure, and a gap is provided between the limiting portion and the elastic connecting portion.

[0024] The utility model has a compact and reasonable structure and is easy to operate. The tubular body structure is lengthened to make it higher than the stud to play a role of a barrier. A plurality of lock heads that are easy to elastically deform and flip are arranged around the central axis in the body structure. The teeth on the lock heads are used to achieve clamping and limiting with the stud. Therefore, while ensuring the connection effect, the insertion force is reduced, and the labor intensity of the operator when installing the fixing seat is reduced, so as to avoid the stud from hurting the operator during the installation process and the stud from damaging the wiring harness connected to the fixing seat during use, thereby ensuring the convenience and safety of the installation operation process.

[0044] An embodiment of the present application provides a fixing seat that is assembled with a stud, which solves the problems in the prior art that the operator has high labor intensity when installing the fixing seat, the stud may cause harm to the operator during the installation process, and the stud may damage the wiring harness connected to the fixing seat during use.

[0045] The technical solution in the embodiment of the present application is to solve the above-mentioned problem. By lengthening the main structure of the fixing seat to play a barrier role, a lock head that is easy to elastically deform and flip is provided in the channel for inserting the fixing seat into the stud. The lock head acts differently from the stud during the insertion and removal process to achieve the effect of low insertion force and high extraction force, thereby effectively solving the problem of high labor intensity and the impact of the stud on external personnel or wiring harnesses during the installation process, thereby ensuring the convenience and safety of the installation operation process.

[0046] In order to better understand the technical solution of the present application, the technical solution is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0047] Example 1:

[0048] like Figure 1-Figure 7 As shown, the fixing seat matched with the stud in this embodiment includes a main body structure 1, a plurality of locking heads 5, a plurality of teeth 51 and a fixing portion 3.

[0049] The main body structure 1 is tubular, and the length of the main body structure 1 is greater than or equal to the length of the stud 8;

[0050] Multiple lock heads 5 are provided on the inner wall of one end of the main body structure 1. Each lock head 5 is elastically connected to the main body structure 1. The multiple lock heads 5 are evenly distributed around the central axis of the main body structure 1.

[0051] A plurality of teeth 51 are provided on one side of each lock head 5 facing the central axis and cooperate with the thread of the stud 8.

[0052] The fixing portion 3 is provided at the other end of the main body structure 1 and is used to set a cable tie 4;

[0053] Among them, when the stud 8 is inserted, the lock head 5 flips toward the inner wall of the main body structure 1; when the teeth 51 on the lock head 5 are embedded in the bottom of the thread from the side of the stud 8, the fixing seat is connected to the stud 8; when the stud 8 is pulled out, the lock head 5 flips toward the center of the main body structure 1, and multiple teeth 51 cooperate with the thread of the stud 8 to limit the fixing seat.

[0054] Specifically, such as Figure 1 As shown, after the stud 8 is inserted from one end of the main body structure 1, it is accommodated inside the main body structure 1, and the fixing portion 3 is located outside the end of the main body structure 1;

[0055] The lock head 5 is elastically connected to the main body structure 1, which facilitates the swinging of the lock head 5 relative to the main body structure 1, so that the insertion force when inserting the stud 8 is small;

[0056] After the stud 8 is inserted, the lowest teeth 51 of the lock head 5 are embedded in the bottom of the thread from the side of the stud 8. Generally, when installing the fixing base, the fixing base is inserted to the bottom until it can no longer move relative to the stud 8. The number of teeth 51 embedded in the bottom of the thread is greater than or equal to two.

[0057] When the stud 8 is pulled out, the bottom teeth 51 engage with the stud 8, causing the lock head 5 to flip toward the center of the main structure 1 when the fixing seat moves relative to the stud 8. The multiple teeth 51 squeeze the stud 8 from both sides and partially embed into the bottom of the thread teeth, preventing the stud 8 from moving. Therefore, a large pulling force is required;

[0058] The cable tie 4 and the fixing portion 3 may be designed as one piece, and the fixing seat may be integrally formed.

[0059] By lengthening the tubular body structure 1 so that it is higher than the stud 8, it acts as a barrier, and multiple lock heads 5 that are easy to elastically deform and flip are arranged around the central axis in the body structure 1. The teeth 51 on the lock heads 5 are used to achieve engagement and positioning with the stud 8, thereby reducing the insertion force while ensuring the connection effect, reducing the labor intensity of the operator when installing the fixing seat, avoiding harm to the operator by the stud 8 during installation, and damage to the wiring harness connected to the fixing seat by the stud 8 during use, thereby ensuring the convenience and safety of the installation operation process.

[0060] Further, if Figure 1 As shown, a reinforcement ring 2 is provided on the outer wall of the main body structure 1 , one side of the fixing portion 3 is connected to the outer wall of the main body structure 1 , and the other side of the fixing portion 3 is connected to the reinforcement ring 2 .

[0061] Specifically, the fixing portion 3 is arranged on the side surface of one end of the main body structure 1, avoiding the middle through hole of the main body structure 1, so as to facilitate observation of the internal stud 8 from the upper end.

[0062] The reinforcement ring 2 is a sheet-like structure. Specifically, the reinforcement ring 2 is a circular ring.

[0063] A reinforcement ring 2 is provided on the outer wall of the main body structure 1, and the fixing part 3 is connected to the main body structure 1 and the reinforcement ring 2 at the same time. The reinforcement ring 2 connects the fixing part 3 to the annular periphery of the main body structure 1, which not only supports the fixing part 3, but also enhances the strength of the main body structure 1, thereby preventing the fixing part 3 from falling off and splitting during the use of the fixing seat.

[0064] In addition, when a carpet is laid on the vehicle body where the stud 8 is fixed, after the fixing seat is installed, the sheet-shaped reinforcement ring 2 contacts the upper surface of the carpet, or is located above the carpet, replacing the carpet fixing buckle to limit the carpet. Specifically, the distance between the reinforcement ring 2 and the insertion end of the main body structure 1 is equal to the thickness of the carpet or slightly greater than the thickness of the carpet.

[0065] In another embodiment, the cable tie 4 is detachably connected to the fixing portion 3. Figure 1 As shown, the fixing portion 3 is provided with a through hole for detachably connecting with the cable tie 4 .

[0066] Example 2:

[0067] In order to minimize the wall thickness of the main body structure 1 and control material costs while ensuring that the overall strength of the main body structure 1 meets the requirements, the fixing seat for assembly with the stud in this embodiment optimizes the internal structure based on the first embodiment, and the specific solution is as follows.

[0068] The inner wall of the main body structure 1 is provided with a plurality of reinforcing ribs 6 , the length direction of the reinforcing ribs 6 is consistent with the length direction of the main body structure 1 , and each reinforcing rib 6 is provided between two adjacent lock heads 5 .

[0069] Specifically, the length of the reinforcing rib 6 is adapted to the length of the adapted stud 8. The reinforcing rib 6 is protrudingly arranged on the inner wall surface of the main body structure 1, which not only reinforces the longer tubular structure of the main body structure 1, but also guides and limits the stud 8 from the outside of the stud 8 when the stud 8 is inserted, thereby preventing the position of the stud 8 from deviating from the center position of the main body structure 1.

[0070] Further, if Figure 3-Figure 4 As shown, the number of the lock heads 5 and the number of the reinforcing ribs 6 are both four.

[0071] The cross section of the main body structure 1 is square, and the four lock heads 5 are respectively located at the four inner corners of the square.

[0072] The main body structure 1 is a square tube, which is not only convenient for operators to hold during the installation of the fixing seat, but also convenient for the arrangement of the four lock heads 5 and the reinforcing ribs 6, further reducing the material usage of the fixing seat.

[0073] Example 3:

[0074] In order to improve the connection strength between the fixing seat and the stud 8, the fixing seat assembled with the stud in this embodiment optimizes the structure of the lock head 5 on the basis of the above embodiment, and the solution is as follows.

[0075] like Figure 5 As shown, the connection positions of the multiple lock heads 5 and the main body structure 1 are located at different cross sections of the main body structure 1, and the two lock heads 5 arranged opposite to each other are located at the same cross section position.

[0076] Specifically, the cross section refers to a cross section that is consistent with the cross section direction of the stud 8 ; the two locking heads 5 arranged opposite to each other are located at the same cross section position, and are mainly used to adapt to threads at different height positions of the stud 8 .

[0077] Multiple lock heads 5 are arranged on the main body structure 1 at different cross-sectional positions to ensure the consistency of the posture of each lock head 5 when mated with the thread, thereby improving the connection strength between the fixing seat and the stud 8.

[0078] like Figure 6 As shown, it also includes an elastic connection part 7, and the lock head 5 is elastically connected to the main body structure 1 through the elastic connection part 7. The cross section of the elastic connection part 7 is smaller than the cross section of the lock head 5.

[0079] Specifically, the cross-sectional dimensions of the elastic connecting portion 7 ensure connection strength and good deformation capability, facilitating the flipping of the lock head 5 .

[0080] like Figure 6 As shown, a limiting portion 52 is provided on the lock head 5 , and the limiting portion 52 is located between the plurality of teeth 51 and the end surface of the main body structure 1 , and there is a gap between the limiting portion 52 and the elastic connecting portion 7 .

[0081] Specifically, the end face of the main body structure 1 refers to the end face facing the position where the stud 8 is set. Figure 6 As shown, the limiting portion 52 is located at the lower end of the multiple teeth 51, which is used to limit the degree to which the two lock heads 5 flip towards each other, thereby preventing the lock heads 5 from flipping at too large an angle, causing the teeth 51 to disengage from the threads and the connection function to fail.

[0082] The number of the multiple teeth 51 is greater than or equal to three, so that when the stud 8 is pulled out, more threads are in contact with the teeth 51, thereby increasing the pulling force and enhancing the stability of the connection between the fixing seat and the stud 8.

[0083] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the scope of protection of the utility model.
