Description

Technical Field

[0001] This utility model belongs to the field of connector technology, and in particular relates to V-shaped high-stability contact force crimping terminals. Background Technology

[0002] PCB crimp terminals, also known as PCB connectors, are indispensable components in electronic devices. They achieve electrical connections between electronic components by inserting into holes on a PCB board. This connection method is not only robust and reliable but also facilitates installation and disassembly, greatly simplifying the manufacturing and maintenance of electronic equipment.

[0003] However, in the existing technology, the conventional way to connect the high-speed connector terminals of the backplane to the PCB is as follows: the PCB is designed with round holes, and the terminal contact area is designed with a hollow teardrop-shaped structure. When the terminal contact area is inserted into the hole of the PCB board, the contact area will be deformed by pressure to provide contact force. However, in the automotive industry, as the reliability requirements are getting higher and higher, the existing hollow connection terminals have a high risk of failure during application. Therefore, a new device needs to be designed. Utility Model Content

[0004] The purpose of this invention is to provide a V-shaped high-stability contact force crimping terminal to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] V-shaped high-stability contact force crimping terminal includes a terminal body, the upper and lower surfaces of which are flat, and a top surface groove provided in the middle of the top surface of the terminal body. A V-shaped elastic body is provided on the bottom surface of the top surface groove. Crimping bodies are symmetrically arranged on both sides of the V-shaped elastic body. A bottom surface groove is provided in the middle of the bottom surface of the terminal body, and the V-shaped elastic body is embedded in the bottom surface groove.

[0007] Furthermore, the outer surface of the presser body is arc-shaped along its length and is divided into a retaining force providing section in the middle and an inlet section at the front end, ensuring that it enters from the inlet section and is tensioned and fixed by the retaining force providing section.

[0008] Furthermore, both the top and bottom grooves are olive-shaped to ensure uniform wall thickness of the press-fit body and improve the uniformity of the force applied by the V-shaped elastomer to the press-fit body.

[0009] Furthermore, the four corners of the pressing body are all rounded, which reduces the scratch damage to the PCB holes during insertion.

[0010] Furthermore, the terminal body, the V-shaped elastomer, and the crimping body are integrally formed, ensuring a strong and secure structure and extending service life.

[0011] Compared with existing technologies, the beneficial effects are:

[0012] 1. When inserting into a PCB hole, the crimp terminal body's guide section first enters the PCB hole, followed by the crimp terminal body's retaining force providing section. The retaining force providing sections on both sides and the central V-shaped elastomer together form an elastic deformation area, providing significant elastic force to ensure reliable contact and friction with the PCB during operation. Simultaneously, the connection points between the two ends of the central V-shaped elastomer and the crimp terminal body are centered in the thickness direction of the crimp terminal, reducing the risk of misalignment between the crimp terminal and the PCB hole during insertion.

[0013] 2. The crimp terminal body is designed with rounded corners at the top and bottom, which reduces scratch damage to the PCB board holes when inserted into them;

[0014] 3. By adjusting the arch height of the central V-shaped elastomer, the overall elasticity of the product can be adjusted to suit different PCB hole sizes, different product materials, and different product and PCB hole plating layers, thereby meeting different market demands.

[0022] 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.

[0023] Please see Figures 1-6 The V-shaped high-stability contact force crimping terminal includes a terminal body 1, the upper and lower surfaces of which are flat, and a top surface groove 2 provided in the middle of the top surface of the terminal body 1. A V-shaped elastic body 3 is provided on the bottom surface of the top surface groove 2. Crimping bodies 4 are symmetrically arranged on both sides of the V-shaped elastic body 3. A bottom surface groove 5 is provided in the middle of the bottom surface of the terminal body 1, and the V-shaped elastic body 3 is embedded in the bottom surface groove 5.

[0024] Furthermore: the outer surface of the crimping body 4 is arc-shaped along its length, divided into a retaining force providing section 41 in the middle and an inlet section 42 at the front end, ensuring that it enters from the inlet section 42 and is tensioned and fixed by the retaining force providing section 41; the top groove 2 and the bottom groove 5 are both olive-shaped to ensure that the wall thickness of the crimping body 4 is uniform and to improve the uniformity of the force applied to the crimping body 4 by the V-shaped elastomer 3; the upper and lower four corners of the crimping body 4 are all rounded corners 43 to reduce the scratch damage to the PCB hole 6 when inserting the board; the terminal body 1, the V-shaped elastomer 3 and the crimping body 4 are integrally formed to ensure that they are strong and secure and extend their service life.

[0025] Working principle: When inserted into PCB hole 6, the guide section 42 at the front end of the crimping body 4 of the terminal body 1 first enters the PCB hole 6, and then the retaining force providing section 41 in the middle of the crimping body 4 enters the PCB hole 6. The retaining force providing sections 41 on both sides and the V-shaped elastic body 3 in the middle together form an elastic deformation area, providing elastic force to ensure reliable contact and friction force between the crimping body and the PCB during operation. At the same time, the connection positions of the two ends of the V-shaped elastic body 3 with the terminal body 1 are centered in the thickness direction of the crimping terminal, reducing the risk of the crimping terminal not being centered with the PCB hole 6 when inserted into the PCB board. The rounded corner 43 designed on the edge of the crimping body 4 reduces the scratch damage to the PCB hole when inserted into the PCB hole 6.
