Description

Technical Field

[0001] The utility model relates to the technology of connector field, in particular to a durable connector and an elastic terminal thereof. Background Art

[0002] Connectors, also known as connectors and sockets in China, generally refer to electrical connectors, which are devices that connect two active devices and transmit current or signals. The male and female ends can transmit information or current through contact, and are also called connectors. Connectors can simplify the assembly process of electronic products and improve product production efficiency. At the same time, if an electronic component fails, products equipped with connectors can quickly replace the failed component. Moreover, as technology advances, upgraded components can be directly connected to the connector, replacing old components with newer and more advanced components. The existence of connectors provides engineers with greater flexibility in their design ideas when designing and integrating new products.

[0003] Connectors are plugged and unplugged many times during use, and during this process, wear and tear occurs between the terminals, shortening the connector's lifespan. Later, some manufacturers used elastic contact to reduce terminal wear. While this elastic contact method can reduce terminal wear, when the male end is plugged in, the terminal is elastically deformed under force. Furthermore, due to the smaller size of the terminal, the contact area with the insulation body is also smaller, and the insulation body cannot provide good support for the terminal. After the male end is unplugged, the terminal will be subjected to long-term high-intensity pressure and will not be able to elastically return to its original shape, shortening the connector's lifespan and making it less durable. Therefore, it is necessary to improve existing connectors. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies in the prior art, and its main purpose is to provide a durable connector and its elastic terminal, which can effectively solve the problem that the insulating body in the existing connector cannot provide good support for the elastic terminal, resulting in the elastic terminal being unable to elastically return to its original shape due to long-term high-intensity pressure, shortening the service life of the connector and making the connector less durable.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An elastic terminal comprises a contact portion, an elastic portion, a body portion and a welding portion which are integrally formed and connected; a reinforcing portion is extended upward from the upper end of the inner side of the body portion.

[0007] As a preferred solution, the main body is provided with a slot located inside the elastic portion. The slot design makes the elastic portion more elastic, which is beneficial to the elastic recovery of the terminal.

[0008] As a preferred solution, the contact portion and the elastic portion form an elastic groove, so that the contact portion has a certain elasticity.

[0009] As a preferred solution, a support portion extending downward is formed on the inner side of the lower end of the main body.

[0010] A durable connector comprises a circuit board, an insulating body and a plurality of the aforementioned elastic terminals; the circuit board has a plurality of solder pads; the insulating body is arranged on the circuit board, and the insulating body is provided with a plurality of terminal slots; the plurality of elastic terminals as described in any one of claims 1 to 4 are respectively arranged in corresponding terminal slots, the contact portion extends outward from the terminal slot, the body portion contacts the inner wall surface of the terminal slot, the welding portion is welded and fixed to the corresponding solder pad, and the reinforcing portion contacts the inner wall surface of the terminal slot.

[0011] As a preferred solution, a positioning hole is provided on the circuit board, and a positioning post extends downward from the bottom of the insulating body. The positioning post is inserted into the positioning hole and fixed, so that the assembly of the insulating body and the circuit board is more precise.

[0012] As a preferred solution, there are two positioning holes, one of which is located on the left side of the circuit board and the other is located on the right side of the circuit board. Correspondingly, there are also two positioning posts, one of which extends downward from the left side of the bottom of the insulating body and the other extends downward from the right side of the bottom of the insulating body.

[0013] As a preferred solution, a limiting groove for cooperating with the male head to limit the position is provided on the side surface of the insulating body.

[0014] As a preferred solution, a plurality of the limiting grooves are arranged at intervals on the left and right.

[0015] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0016] By extending a reinforcement portion upward from the upper end of the inner side of the main body, the design of the reinforcement portion makes the elastic terminal of the present invention have a larger contact area with the insulating body compared with the traditional elastic terminal, providing the elastic terminal with a higher support point and greater supporting force. When plugged into the male end, the reinforcement portion can transfer more force to the insulating body, reducing the strength of the elastic terminal, and thus making the elastic terminal able to elastically recover to its original shape after long-term stress, effectively extending the service life of the connector and making the connector more durable.

[0031] Please refer to Figures 1 to 3 , which shows the specific structure of a preferred embodiment of the present invention, including a circuit board 10 , an insulating body 20 and a plurality of elastic terminals 30 .

[0032] The circuit board 10 has a plurality of solder pads 11 . In this embodiment, the circuit board 10 is provided with positioning holes 12 . There are two positioning holes 12 , one of which is located on the left side of the circuit board 10 and the other is located on the right side of the circuit board 10 .

[0033] The insulating body 20 is arranged on the circuit board 10, and the insulating body 20 is provided with a plurality of terminal slots 21. In this embodiment, a positioning column 22 extends downward from the bottom of the insulating body 20, and the positioning column 22 is inserted into the positioning hole 12 for fixing, so that the assembly of the insulating body 20 and the circuit board 10 is more precise. There are also two positioning columns 22, one of which extends downward from the left side of the bottom of the insulating body 20, and the other extends downward from the right side of the bottom of the insulating body 20; in addition, a limiting groove 23 for cooperating with the male head is provided on the side of the insulating body 20, and a plurality of limiting grooves 23 are arranged at intervals on the left and right.

[0034] The multiple elastic terminals 30 are respectively arranged in the corresponding terminal slots 22. The multiple terminals 30 include a contact portion 31, an elastic portion 32, a main body portion 33 and a welding portion 34 that are integrally formed and connected; the contact portion 31 extends outward from the terminal slot 22, and the main body portion 33 contacts the inner wall surface of the terminal slot 21. The upper end of the inner side of the main body portion 33 extends upward to form a reinforcement portion 35, which contacts the inner wall surface of the terminal slot 21. The welding portion 34 is welded and fixed to the corresponding pad 11. In this embodiment, the main body portion 33 is provided with a hollow groove 331, which is located on the inner side of the elastic portion 32. The hollow groove 331 design makes the elastic portion 32 more elastic, which is conducive to the elastic recovery of the terminal; and the contact portion 31 and the elastic portion 32 are surrounded to form an elastic groove 301, so that the contact portion 31 has a certain elasticity; in addition, a support portion 36 extending downward is formed on the inner side of the lower end of the main body portion 33, and the upper end of the support portion 36 contacts the insulating body 20, and the lower end of the support portion 36 contacts the surface of the circuit board 20.

[0035] The working principle, usage method or working process of this embodiment are described in detail as follows:

[0036] First, multiple elastic terminals 30 are placed in a mold, and the insulating body 20 is formed by injection molding. The contact portion 31 extends outward from the terminal slot 22, and the first clamping point 331 and the second clamping point 332 are buried in the insulating body 20. Then, the insulating body 20 is installed on the circuit board 10, and the positioning column 22 is inserted into the positioning hole 12 for fixation. Then, the welding portions 34 of the multiple elastic terminals 30 are welded to the pad 11.

[0037] The design focus of the present invention is that a reinforcement portion is extended upward from the upper end of the inner side of the main body. The design of the reinforcement portion enables the elastic terminal of the present invention to have a larger contact area with the insulating body than the traditional elastic terminal, providing the elastic terminal with a higher support point and greater supporting force. When plugged into the male end, the reinforcement portion can transfer more force to the insulating body, reducing the strength of the elastic terminal. As a result, the elastic terminal can still elastically recover to its original shape after being subjected to long-term force, effectively extending the service life of the connector and making the connector more durable.
