Description

Technical Field

[0001] This utility model relates to the field of connectors, and more specifically to a board-type connector terminal. Background Technology

[0002] Existing board-mounted connection terminals typically include an insulator (a plastic frame or a plastic body) and a terminal assembly. To achieve a recessed board effect, the insulator is usually attached to the circuit board, one end of the terminal assembly is soldered to the circuit board, and the other end extends along the circuit board and then curves upward toward the top of the circuit board.

[0003] However, under high-intensity use, because the board-type connection terminals need to face a large number of insertions and removals from the side, when the terminals come into contact with the external connectors, a lot of friction will be generated between the terminals and the external connectors. Over a long period of time, this friction will cause great wear on the surface of the terminals, which may cause the terminals and external connectors to lose their resilience under long-term high-intensity use. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a plate-mounted connecting terminal, comprising an insulating frame. Several partitions are arranged at preset intervals within the insulating frame, dividing the interior of the frame into several receiving slots. A connecting terminal is disposed within each receiving slot. The connecting terminal includes a fixing part, an upward-curving part, and an elastic part. One end of the fixing part is fixed to a circuit board. The upward-curving part extends along the fixing part into the receiving slot and bends upward toward the top of the circuit board. The elastic part is disposed at the end of the upward-curving part away from the fixing part, protruding toward the top of the circuit board. A contact surface is provided on the elastic part, and the contact surface is spherical in shape.

[0005] Furthermore, the insulating frame includes a top surface, a bottom surface, and a side surface surrounding the top and bottom surfaces. The bottom surface of the insulating frame is in close contact with the circuit board, and the side surface of the insulating frame wraps around the fixing part.

[0006] Furthermore, the connection terminal includes a first terminal and a second terminal arranged in parallel, with the first terminal disposed between the second terminals, and the width of the second terminal being greater than the width of the first terminal.

[0007] Furthermore, a U-shaped bend is formed on the top surface of the elastic portion toward the circuit board, and the bend is bent toward the top surface of the insulating frame.

[0008] Furthermore, the contact surface is located at the top of the curved portion. Furthermore, a downwardly protruding boss is provided on the bottom surface of the insulating frame, and a positioning groove that can cooperate with the boss is provided on the circuit board. When the bottom surface of the insulating frame is in close contact with the circuit board, the boss is inserted into the positioning groove and an interference fit is formed between the two.

[0009] Furthermore, the insulating frame and the boss are made of plastic, which provides better insulation performance. Furthermore, a reinforcing rib is provided at the top of the upturned portion.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This application provides a contact surface on the elastic part, and the contact surface is spherical in shape. This reduces the friction between the elastic part and the external connector when the elastic part comes into contact, resulting in a smoother rebound of the elastic part.

[0018] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0019] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings. Figure 1 , Figure 2 and Figure 3As shown, the board-type connection terminal includes an insulating frame 100. Several partitions 110 are arranged at preset intervals within the insulating frame 100, dividing the interior of the frame into several receiving grooves 120. A connection terminal 200 is arranged within each receiving groove 120. The connection terminal 200 includes a fixing part 210, an upward-curving part 220, and an elastic part 230. One end of the fixing part 210 is fixed to the circuit board 300. The upward-curving part 220 extends along the fixing part 210 into the receiving groove 120 and bends upward toward the top of the circuit board 300. The elastic part 230 is located at the end of the upward-curving part 220 away from the fixing part 210 and protrudes toward the top of the circuit board 300. A contact surface 231a is provided on the elastic part 230, and the contact surface 231a is spherical in shape.

[0020] During the installation of this embodiment, different connecting terminals 200 are first combined with the insulating frame 100 by injection molding, so that the different connecting terminals 200 are inserted into different receiving slots 120. Then, the insulating frame 100 is assembled with the circuit board 300. During the assembly process, the top of the insulating frame 100 is fixedly connected to the top of the circuit board 300. Then, the connecting terminals 200 are soldered to the circuit board 300.

[0021] Compared to existing technologies, this application provides a contact surface 231a on the elastic part 230, and the contact surface 231a is spherical in shape. This reduces the friction between the elastic part 230 and the external connector when the elastic part 230 comes into contact, resulting in a smoother rebound of the elastic part 230.

[0022] Furthermore, based on the above embodiments, such as Figure 3 As shown, the insulating frame 100 includes a top surface 130, a bottom surface 140, and a side surface 150 surrounding the top surface 130 and the bottom surface 140. The bottom surface 140 of the insulating frame 100 is in close contact with the circuit board 300, and the side surface 150 of the insulating frame 100 surrounds the fixing part 210. In this way, one end of the connecting terminal 200 can be fixed to the circuit board 300 by soldering, and the fixing part 210, through the wrapping of the side surface 150 of the insulating frame 100, allows the connecting terminal 200 to be better fixed to the circuit board 300.

[0023] Furthermore, based on the above embodiments, such as Figure 2As shown, the connection terminal 200 includes a first terminal 240 and a second terminal 250 arranged in parallel. The first terminal 240 is disposed between the second terminal 250. The width of the second terminal 250 is greater than the width of the first terminal 240. This increases the contact area 231a between the two ends of the connection terminal 200 and the circuit board 300. When one end of the connection terminal 200 is fixed to the circuit board 300 by soldering, the stability of the connection between the connection terminal 200 and the circuit board 300 can be further improved.

[0024] Furthermore, based on the above embodiments, such as Figure 2 As shown, a U-shaped bend 231 is formed on the top of the elastic portion 230 toward the top of the circuit board 300. The bend 231 bends toward the top of the insulating frame 100. This allows the contact portion to better contact other connectors and form an elastic electrical connection when it extends beyond the circuit board 300. Preferably, the contact surface 231a is located on the top of the bend 231.

[0025] Furthermore, based on the above embodiments, such as Figure 4 As shown, a downwardly protruding boss 141 is provided on the bottom surface 140 of the insulating frame 100, and a positioning groove 310 is provided on the circuit board 300 to cooperate with the boss 141. When the bottom surface 140 of the insulating frame 100 is in close contact with the circuit board 300, the boss 141 is inserted into the positioning groove 310, and an interference fit is formed between the two. Compared with the traditional bonding between the insulating frame 100 and the circuit board 300, the connection between the insulating frame 100 and the circuit board 300 can be more secure and less prone to detachment when facing high-intensity insertion and removal.

[0026] Furthermore, based on the above embodiments, the insulating frame 100 and the boss 141 are made of plastic, which can provide better insulation performance.

[0027] Furthermore, a reinforcing rib 221 is provided at the top of the upturned portion 220. The reinforcing rib 221 can increase the bending strength of the upturned portion 220, so that when the upturned portion 220 moves in conjunction with the elastic portion 230 under high strength, it is not easy for the upturned portion 220 to suffer metal fatigue and breakage.

[0028] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
