[0001] This utility model relates to the field of terminal connector technology, and in particular to a terminal that can be smoothly plugged in. Background Technology

[0002] In existing electrical systems, terminal connections are key components for achieving electrical connections. Some existing terminals use clamping plates to hold conductive components such as inserts. Due to the small size of the socket and the lack of a guiding structure, conductive components are not easily inserted into the terminal socket, resulting in problems with smooth insertion. Utility Model Content

[0003] This invention provides a terminal that allows for smooth insertion, which can guide conductive devices to be inserted into the terminal, making the insertion process smoother.

[0004] To solve the above problems, the present invention adopts the following technical solution:

The two connecting plates are located on both sides of the base plate, and the lower ends of the two connecting plates are connected to the base plate. The two pressure plates are connected to the upper ends of the two connecting plates and extend towards each other. The spring is located below the pressure plates, with one end connected to the base plate and the other end extending rearward. The spring includes a guide portion, the height of which gradually increases in the rearward direction.

[0006] In some embodiments, the spring sheet further includes a starting portion and a bending portion. The starting portion is located on the front side of the insertion base plate. One end of the starting portion is connected to the insertion base plate, and the other end extends forward.

[0020] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0021] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0023] Embodiments of this utility model provide a terminal that can be smoothly plugged in, such as... Figure 1-3 As shown, the device includes a terminal block 100 and a connector 200. The terminal block 100 is used to connect wires for transmitting electrical signals, while the connector 200 is used for inserting conductive devices such as plugs. The connector 200 is located at the front end of the terminal block 100 and includes a base plate 210, two connecting plates 220, two pressure plates 230, and a spring 240. The two connecting plates 220 are located on both sides of the base plate 210, and their lower ends are connected to the base plate 210. The two pressure plates 230 are connected to the upper ends of the two connecting plates 220, and they extend towards each other, i.e., they extend in a direction closer to each other. The spring 240 is located below the pressure plates 230. The two connecting plates 220, the two pressure plates 230, and the spring 240 together form a socket. One end of the spring piece 240 is connected to the insertion base plate 210, and the other end extends backward; the spring piece 240 includes a guide portion 241, and the height of the guide portion 241 gradually increases in the direction of extending backward.

[0024] When the conductive device is inserted into the terminal of this embodiment, due to the obliquely arranged structure of the guide portion 241, the entrance end of the socket is relatively large, making it easy for the conductive device to be inserted between the spring piece 240 and the pressure plate 230. The conductive device will abut against the guide portion 241 of the spring piece 240. Under the guidance of the guide portion 241, the conductive device gradually contacts the pressure plate 230, and finally the pressure plate 230 and the spring piece 240 hold the conductive device. This can guide the conductive device to be inserted into the terminal of this embodiment, making the terminal insertion smoother.

[0025] In some embodiments, the spring 240 further includes a starting portion 242 and a bending portion 243. The starting portion 242 is located on the front side of the insertion base plate 210. One end of the starting portion 242 is connected to the insertion base plate 210, and the other end extends forward. One end of the bending portion 243 is connected to the front end of the starting portion 242, and the other end bends upward and then backward. The end of the bending portion 243 away from the starting portion 242 is connected to the front end of the guide portion 241.

[0026] This structure makes the guiding function of the spring 240 continuous. When the conductive device first comes into contact with the bend 243, it can also move along the arc structure of the bend 243 to the guide 241, which can better guide the conductive device to the terminal.

[0027] In this embodiment, the starting portion 242, the bending portion 243, and the guiding portion 241 can be integrally formed, which facilitates the manufacturing of the spring piece 240 and also strengthens the connection between them. Specifically, the starting portion 242, the bending portion 243, and the guiding portion 241 can be integrally formed by stamping or bending processes.

[0028] In some embodiments, both connecting plates 220 are recessed inward at their midpoints in the height direction. This recess helps improve the toughness of the connecting plates 220, making them less prone to deformation. Specifically, the recesses can be stamped into the two connecting plates 220 using a stamping process.

[0029] In some embodiments, the connector 200 further includes two baffles 250, which are respectively connected to both sides of the connector base plate 210 and are located on the rear side of the two connecting plates 220. The distance between the two baffles 250 gradually decreases in the rearward direction.

[0030] Because the width of the terminal block 100 is relatively small, while the width of the connector 200 is relatively large, this structure of the baffle 250 can accommodate the narrower terminal block 100, allowing the baffle 250 to connect with the terminal block 100. Simultaneously, since the connecting plate 220 does not extend further rearward, the baffle 250 acts as an extension of the connecting plate 220, which strengthens the structural rigidity of both sides of the connector base plate 210, making it less prone to deformation.

[0031] In some embodiments, the connector 200 further includes a snap plate 260, which is connected to the connector base plate 210 and extends below the connector base plate 210.

[0032] When installing terminals, the snap plate 260 can be connected to the connector housing to position the terminals. The snap plate 260 can extend diagonally downward and backward. The snap plate 260 and the insertion base plate 210 can be integrally formed, specifically by stamping the snap plate 260.

[0033] In some embodiments, the terminal block 100 includes a U-shaped positioning plate 110 and a U-shaped pressure plate 120. The positioning plate 110 is located in front of the pressure plate 120, and the pressure plate 120, the positioning plate 110, and the insertion base plate 210 are sequentially connected from back to front. When connecting the terminal to the wire, the wire is placed inside the pressure plate 120 and the positioning plate 110. The positioning plate 110 is used to position the wire and restrict the wire from swaying left and right. The two sides of the pressure plate 120 can be bent towards each other, thereby pressing on the wire and clamping the wire in a clamping state to realize the connection between the wire and the terminal.

[0034] Furthermore, the inner surface of the positioning plate 110 is provided with a protruding ridge 111. The protruding ridge 111 can increase the friction, making it less likely for the wire to detach from the terminal and improving the stability of the connection between the wire and the terminal. The protruding ridge 111 can also be formed by stamping.

[0035] In some embodiments, the terminal block 100 and the plug 200 are integrally formed. Specifically, the positioning plate 110, pressure plate 120, plug base plate 210, connecting plate 220, pressure plate 230 and spring plate 240 in the above embodiments can be integrally formed. Specifically, they can be formed by stamping and / or bending processes to facilitate the overall manufacturing of the terminals and to strengthen the connection strength between them.

[0036] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
