Description

Technical Field

[0001] The utility model relates to the field of electrical connectors, and particularly to an LVDS connector with stable contact. Background Art

[0002] An LVDS connector is a connector that uses low-voltage differential signal technology. The LVDS connector transmits data at high speed with extremely low voltage swings through a pair of differential signal lines, and has characteristics such as low power consumption, low bit error rate, low crosstalk, low jitter, and low radiation. This technology can achieve data transmission rates of thousands of megabits, and because it is driven in a constant current source mode, it only generates extremely low noise and consumes very little power. LVDS connectors are widely used in scenarios that require high-speed, stable, and low-power data transmission, such as liquid crystal displays, industrial automation, medical equipment, network communication, and other fields. It has strong anti-interference ability and can maintain low signal distortion during long-distance transmission, meeting the application requirements with high signal quality requirements. In addition, the LVDS connector also has good environmental adaptability and can adapt to complex environments such as large voltage change ranges of the ground plane.

[0003] The conductive terminals of existing LVDS connectors are usually as Figure 8 shown. It adopts a straight-arm design for easy insertion into the insulating body. However, due to its relatively simple structure, the elasticity it can generate is small, resulting in problems such as poor contact, signal attenuation, and even connection failure during use. Especially in the face of harsh environments such as vibration and impact, its stability is even more difficult to guarantee. This affects the reliability of data transmission and the overall performance of the device. Therefore, the utility model proposes an LVDS connector with stable contact. Summary of the Invention

Detailed implementation manner

[0027] The present utility model will be further described in detail below in conjunction with the accompanying drawings and the detailed implementation manner.

[0028] In this embodiment, referring to Figures 1 - 7 , a LVDS connector with stable contact in its specific implementation includes an insulating body 1, a conductive terminal 2 installed in the insulating body 1, and a housing 3 sleeved outside the insulating body 1. The conductive terminal 2 includes a conductive body 201, a fixing arm 202, an elastic arm 203, and a grounding pin 204. One end of the conductive body 201 is provided with a stopper 2011 for cooperating with the insulating body 1. The fixing arm 202 extends outward from one end of the conductive body 201. The upper end of the fixing arm 202 is provided with a fixing block 2021. The insulating body 1 is provided with a fixing groove 101 for cooperating with the fixing block 2021. The insulating body 1 is provided with a through hole for installing the conductive terminal 2. When the conductive terminal 2 is inserted into the through hole, the fixing block 2021 causes the fixing arm 202 to deform downward. When reaching the position of the fixing groove 101, the fixing arm 202 automatically rebounds to complete the cooperation between the fixing block 2021 and the fixing groove 101. And the stopper 2011 on the conductive body 201 fits against the insulating body 1, thereby ensuring that the conductive terminal 2 is stably installed in the insulating body 1. The elastic arm 203 is connected and cooperated with the lower end of the fixing arm 202 through the bending elastic portion 205. There is a certain gap between the bending elastic portion 205 and the conductive body 201. When the elastic arm 203 is subjected to pressure and deforms, the bending elastic portion 205 can provide sufficient elastic restoring force, enabling the elastic arm 203 to generate sufficient elastic deformation to ensure that the contact portion 2032 maintains a stable contact pressure with the connection target. The grounding pin 204 extends outward from the other end of the conductive body 201.

[0029] Furthermore, the elastic arm 203 includes a downwardly inclined connection portion 2031 and an upwardly tilted contact portion 2032. The downwardly tilted connection portion 2031 provides the elastic arm 203 with greater room for elastic deformation when subjected to external forces, thereby improving the contact stability between the contact portion 2032 and the connection target. The upward tilt of the contact portion 2032 ensures that when the connection target is inserted, the contact portion 2032 can effectively contact and maintain a certain contact pressure, preventing unstable signal transmission caused by poor contact.

[0030] Furthermore, the contact portion 2032 is arc-shaped. This allows for more uniform contact between the contact portion 2032 and the connection target, thereby improving contact stability and reliability. The arc-shaped design of the contact portion 2032 can accommodate connection targets of varying thicknesses and shapes, ensuring good contact in all conditions.

[0031] Furthermore, the fixing block 2021 and the insulating body 1 are respectively provided with a guide angle 2022 and a guide structure 102 for mutual cooperation. The cooperation between the guide angle 2022 and the guide structure 102 allows the conductive terminal 2 to be inserted into the through hole more smoothly, and the fixing arm 202 is gradually bent downward, thereby preventing the fixing arm 202 from being suddenly stressed and causing breakage during insertion.

[0032] Furthermore, the housing 3 is provided with an inwardly curved plate 301, the insulating body 1 is provided with a receiving groove that cooperates with the curved plate 301, and the curved plate 301 is provided with a downwardly inclined pressing arm 302. The pressing arm 302 ensures that the connecting object, after being inserted into the insulating body 1, can be firmly pressed downward against the side with the conductive terminals 2, thereby reducing the incidence of poor contact between the connecting object and the conductive terminals 2.

[0033] Furthermore, the insulating body 1 is provided with a positioning groove 103 that cooperates with the bent plate 301. The positioning groove 103 allows the bent plate 301 to be accurately positioned after being inserted into the insulating body 1, ensuring a tight fit between the housing 3 and the insulating body 1. It also serves as a support point for the bent plate 301, improving the stability and durability of the overall structure.

[0034] Furthermore, the lower end of the insulating body 1 is provided with a slot 104, and the housing 3 is provided with a bent block 303 that cooperates with the slot 104. When the insulating body 1 is mounted on the housing 3, the cooperation between the slot 104 and the bent block 303 enables precise positioning between the insulating body 1 and the housing 3. The elastic deformation of the bent block 303 provides sufficient pressure to ensure a tight fit between the insulating body 1 and the housing 3, thereby improving the stability and reliability of the overall connector.

[0035] Advantages of the present utility model: By means of the cooperation between the fixing block 2021 and the fixing groove 101, and through the cooperation between the stopper 2011 and the insulating body 1, the conductive terminal 2 is stably installed in the insulating body 1. Further, the elastic arm 203 is connected to the lower part of the fixing arm 202 through the bent elastic part 205, so that the elastic arm 203 can generate sufficient elastic deformation, thereby improving the contact stability and signal transmission quality of the connector.
