Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a novel 250 terminal. Background Technology

[0002] The 250 terminal is a standard connector terminal widely used in ballasts, transformers, switching power supplies, instruments, and other fields. Existing 250 terminals have two clamping tabs at the insertion point. After the external conductive device (such as a conductive sheet) is inserted into the terminal, the clamping tabs press against it. However, the distance between the clamping tabs and the conductive device is relatively large, sometimes resulting in insufficient pressure on the conductive device, leading to unstable terminal connections. Utility Model Content

[0003] This invention provides a novel 250 terminal that can improve the stability of terminal connection.

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

[0005] This utility model provides a novel 250 terminal block, including a terminal block and a connector. The terminal block is used to connect wires. The connector is disposed at the front end of the terminal block and includes a base plate, two connecting plates, and two pressure plates. 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 middle part of the two pressure plates protrudes downward to form a boss.

[0006] In some embodiments, the connector further includes a spring piece, the front end of which is connected to the connector base plate, and the rear end is provided with an upwardly protruding baffle; the spring piece is inclined, and the height of the spring piece gradually increases in the direction of rearward extension.

[0007] In some embodiments, the top surface of the spring is provided with a protrusion.

[0008] In some embodiments, the outer side of the connecting plate is provided with reinforcing ribs that extend to the top surface of the pressing sheet.

[0009] In some embodiments, the outer surface of the connecting plate is provided with indentations.

[0010] In some embodiments, the terminal block includes a U-shaped positioning plate and a U-shaped pressure plate, the positioning plate being located on the front side of the pressure plate, the positioning plate being used to position the wire, and the pressure plate being bendable.

[0011] In some embodiments, the inner side of the positioning plate is provided with a protruding ridge.

[0012] In some embodiments, the terminal block and the connector are integrally formed.

[0013] The present invention has at least the following beneficial effects: the middle part of the pressure plate of the present invention protrudes downward to form a boss. The distance between the boss and the insertion base plate is closer. When the conductive device is inserted into the terminal, the boss is more likely to abut against the conductive device, thereby providing a tight pressure on the conductive device and improving the stability of the terminal insertion.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] An embodiment of this utility model provides a novel 250-terminal, such as... Figure 1 and Figure 2 As shown, the device includes a terminal block 100 and a connector 200. The terminal block is used to connect wires to transmit electrical signals. The connector 200 is located at the front end of the terminal block 100. The connector 200 includes a base plate 210, two connecting plates 220, and two pressure plates 230. 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., towards each other. Thus, the base plate 210, the two connecting plates 220, and the two pressure plates 230 form a slot for inserting conductive devices such as conductive sheets. The entire connector 200 has a similar square cylindrical structure. The middle part of each of the two pressure plates 230 protrudes downward to form a boss 231, which can be formed by a stamping process.

[0023] Due to the presence of the boss 231, the distance between the boss 231 and the insertion base plate 210 is closer. When the conductive device is inserted into the slot, the boss 231 can more easily abut against the conductive device, thereby providing tight pressure to the conductive device and improving the stability of the terminal insertion.

[0024] In some embodiments, the connector 200 further includes a spring piece 240, the front end of which is connected to the connector base plate 210, and the rear end is provided with an upwardly protruding baffle 241; the spring piece 240 is inclined, and the height of the spring piece 240 gradually increases in the direction of rearward extension.

[0025] The spring 240 provides elastic restoring force. During the insertion of the conductive device into the slot, the conductive device gradually presses the spring 240 downward. The spring 240 provides an upward elastic restoring force to the conductive device, so that the spring 240 and the boss 231 jointly clamp the conductive device, further strengthening the clamping force on the conductive device and improving the stability of the terminal connection.

[0026] The baffle 241 can limit the insertion depth of the conductive device. When the conductive device is inserted to the point of abutting the baffle 241, it is difficult for the conductive device to be inserted further, thus preventing the conductive device from being over-inserted.

[0027] In some embodiments, the top surface of the spring 240 is provided with a protrusion 242, and a groove adapted to the protrusion 242 can be provided on the conductive device. When the conductive device is inserted into the position, the protrusion 242 can be embedded in the groove on the conductive device to position the conductive device, making it less likely for the conductive device to fall out of the terminal slot, thereby further improving the stability of the insertion.

[0028] In some embodiments, the outer side of the connecting plate 220 is provided with a reinforcing rib 221, which extends to the top surface of the pressure plate 230. The reinforcing rib 221 can improve the structural strength, increase the toughness of the pressure plate 230 and the connecting plate 220, making them less prone to deformation and extending the service life of the terminal.

[0029] In some embodiments, the outer surface of the connecting plate 220 is provided with an indentation 222, which can also be formed by a stamping process.

[0030] 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.

[0031] In some embodiments, the inner surface of the positioning plate 110 is provided with a protruding ridge 130. The protruding ridge 130 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 130 can also be formed by stamping.

[0032] 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.
