Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire harness connection structures, and in particular to a wire harness connection structure for relays. Background Technology
[0002] With the increasing prevalence of electronic devices and rapid technological development, relays, as an important electrical component, are widely used in automation control, power systems, home appliances, and other electronic equipment. The reliability and connection quality of relays directly affect the safety and stability of the entire system. Therefore, how to effectively connect relays to wiring harnesses to ensure good electrical contact and mechanical fixation has become an urgent problem to be solved.
[0003] Operators typically need to hold the wire steady with one hand while using a screwdriver to turn the screw with the other. This requires both hands to work together, making the process cumbersome and reducing efficiency. This is especially true when multiple connections need to be made quickly, as it is time-consuming and laborious. Because one hand needs to hold the wire in place, the wire is prone to shifting during clamping, reducing clamping stability and potentially leading to an insecure connection. While keeping the wire steady, operators may not be able to focus on turning the screw, resulting in clamping that is either too tight or too loose, affecting the connection quality. Summary of the Invention
[0004] The purpose of this invention is to provide a wiring harness connection structure for relays to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a relay wiring harness connection structure, comprising:
[0006] Relay body;
[0007] A wire harness positioning structure is installed on the front and back of the relay body, and the wire harness positioning structure includes:
[0008] A support platform, which is mounted on the relay body, is used to support the wire harness;
[0009] An elastic clamping mechanism, wherein multiple elastic clamping mechanisms are interspersed on the support platform, and the elastic clamping mechanism is used to clamp the wire harness;
[0010] An adjustable limiting mechanism is inserted and installed at the bottom of the elastic clamping mechanism.
[0011] Preferably, the top of the support platform is provided with multiple grooves, and the grooves correspond to the positions of the elastic clamping mechanism.
[0012] Preferably, the groove is V-shaped.
[0013] Preferably, the elastic clamping mechanism includes:
[0014] A pressure plate, which is located directly above the groove and has a handle attached to it;
[0015] An insert rod is fixedly connected to a pressure plate and slidably inserted into a support platform.
[0016] The first spring is movably sleeved on the outside of the insert rod. The first spring is used to provide elastic support force to the adjustable limiting mechanism, so that the pressure plate tends to move towards the bearing platform.
[0017] Preferably, the adjustable limiting mechanism includes:
[0018] An interlocking plate, wherein the interlocking plate is slidably interlocked with the interlocking rod;
[0019] A two-way snap-fit assembly is mounted on the insertion plate and is used to snap the insertion rod in order to achieve relative positioning between the elastic clamping mechanism and the insertion plate.
[0020] Preferably, the bidirectional snap-fit assembly includes:
[0021] A fixing base is fixedly installed on the through plate, and the fixing base is a hollow box-shaped structure;
[0022] The second spring is disposed inside the fixed base;
[0023] The slide plate is connected to both ends of the second spring, and the slide plate is movably connected to the fixed base;
[0024] A snap-fit post is provided, one end of which is fixedly connected to the slide plate. The insert rod has multiple slots, and the slide plate passes through the fixed seat and cooperates with the inner cavity of the slots.
[0025] Preferably, the bidirectional snap-fit assembly further includes:
[0026] The guide rod is fixedly installed inside the fixed base, and the guide rod is movably connected to the second spring and the slide plate.
[0027] The technical effects and advantages of this utility model are as follows:
[0028] This invention utilizes a combination of a support platform and an elastic clamping mechanism. By raising the elastic clamping mechanism, the wire harness is inserted into the connector through the gap between the support platform and the elastic clamping mechanism. Then, the pull on the elastic clamping mechanism is released, allowing it to press and position the wire harness. This enables the connection between the wire harness and the connector, facilitating the connection between the wire harness and the relay. When rotating the bolt at the connector, the wire harness does not need to be held by hand, allowing for greater focus on tightening the bolt. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] This utility model provides, for example Figure 1-4The diagram illustrates a relay wiring harness connection structure, comprising: a relay body 1; a wiring harness positioning structure 2, mounted on the front and back of the relay body 1, the wiring harness positioning structure 2 including: a support platform 21, mounted on the relay body 1, the support platform 21 for supporting the wiring harness; an elastic clamping mechanism 22, multiple elastic clamping mechanisms 22 interposed on the support platform 21, the elastic clamping mechanism 22 for clamping the wiring harness; and an adjustable limit mechanism 23, the adjustable limit mechanism 23 interposed at the bottom of the elastic clamping mechanism 22, the elastic clamping mechanism 22 facilitating the clamping of the wiring harness, and the adjustable limit mechanism 23 facilitating the clamping of the wiring harness. The positioning mechanism 23 is convenient for accommodating wire harnesses of various thicknesses, while also adjusting the clamping force of the elastic clamping mechanism 22. By raising the elastic clamping mechanism 22, the wire harness is placed into the connector through the gap between the support platform 21 and the elastic clamping mechanism 22. Then, the pull on the elastic clamping mechanism 22 is released, so that the elastic clamping mechanism 22 presses on the wire harness, clamping and positioning the wire harness. Then, the connection between the wire harness and the connector can be made to assist in the connection between the wire harness and the relay. When rotating the bolt at the connector, it is not necessary to hold the wire harness with your hand, so you can focus more on tightening the bolt at the connector. Example
[0036] The top of the support platform 21 has multiple grooves 211, which correspond to the positions of the elastic clamping mechanism 22. The grooves 211 are V-shaped, which facilitates the support of wire harnesses of various diameters through the inner walls on both sides of the grooves 211.
[0037] The elastic pressing mechanism 22 includes: a pressure plate 221, located directly above the groove 211, with a handle connected to it; an insert rod 222, fixedly connected to the pressure plate 221 and slidably inserted into the support platform 21; and a first spring 223, movably sleeved outside the insert rod 222, which provides elastic support to the adjustable limiting mechanism 23, causing the pressure plate 221 to... 1. It tends to move towards the support platform 21. The pressure plate 221 facilitates the clamping of the wire harness. The sliding insertion between the insertion rod 222 and the support platform 21 facilitates the limiting of the sliding of the pressure plate 221, making the vertical linear movement of the pressure plate 221 more stable. The compression deformation of the first spring 223 facilitates the elastic support of the adjustable limiting mechanism 23, so that the pressure plate 221 tends to move downward under the connection of the insertion rod 222. Example
[0038] Based on Embodiment 1, the adjustable limiting mechanism 23 includes: an insertion plate 231, which is slidably inserted into and connected to an insertion rod 222; and a bidirectional locking assembly 232, which is mounted on the insertion plate 231 and is used to lock the insertion rod 222 to achieve relative positioning between the elastic pressing mechanism 22 and the insertion plate 231. The bidirectional locking assembly 232 includes: a fixed seat 2321, which is fixedly mounted on the insertion plate 231 and is a hollow box-shaped structure; a second spring 2322, which is disposed inside the fixed seat 2321; a sliding plate 2323, which is connected to both ends of the second spring 2322 and is movably connected to the fixed seat 2321; and a locking post 2324, one end of which is fixed to the sliding plate 2323. The connecting rod 222 has multiple slots, through which the sliding plate 2323 passes and engages with the inner cavity of the slots. A guide rod 2325 is fixedly installed inside the fixed base 2321 and is simultaneously movably connected to the second spring 2322 and the sliding plate 2323. By relative compression of the two sliding plates 2323, the sliding plates 2323 can move linearly relative to each other under the limitation of the guide rod 2325, allowing the sliding plates 2323... The engaging pin 2324 moves away from the insert rod 222, causing it to disengage from the insert rod 222. At this point, the bidirectional engaging assembly 232 no longer limits the relative position between the insert plate 231 and the insert rod 222, allowing adjustment of the insertion position between them. This changes the relative position between the pressure plate 221 and the insert plate 231, adjusting the spring force of the first spring 223. After the position of the insert plate 231 is properly adjusted, the external force applied to the slide plate 2323 is released. The elastic support force of the second spring 2322 on the two slide plates 2323 allows the locking post 2324 to engage with the slot on the insertion rod 222, so as to reposition the relative position between the insertion plate 231 and the insertion rod 222. The locking post 2324 is inserted between the fixing seat 2321 and the insertion rod 222, which facilitates the adjustment of the insertion position of the insertion plate 231.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
