Description

Technical Field

[0001] The utility model relates to the technology of terminal block field, in particular to a side-outlet terminal block with stable connection process. Background Art

[0002] Terminal blocks are electronic components used for circuit connection, also called terminal blocks, electrical connectors, etc. Electrical connectors consist of fixed-end electrical connectors (sockets) and free-end electrical connectors (plugs). The socket is fixed to the electrical component through its square (round) disk (some are also welded), and the plug is generally connected to the cable, and the plug and socket are connected through the connecting nut; the terminal block includes not only terminals for external plugging, but also power lines for external power connection and signal lines for signal transmission.

[0003] The connection terminals and the wires in the terminal block need to be welded and then injection molded. However, since the welding part of the existing connection terminals is a planar structure, the wires need to be manually positioned when welding with the wires, and then welding is performed, which makes the welding process more troublesome. At the same time, the wires and the connection terminals are in single-sided contact with a small contact area, which affects the size of the current passing through the wires and makes it unable to meet the use scenarios of large currents. Therefore, it is necessary to further improve the existing terminal block structure. Utility Model Content

[0004] In view of this, the utility model aims to address the deficiencies in the prior art, and its main purpose is to provide a side-outlet terminal block with a stable connection process, which can effectively solve the problems of the existing terminal block, such as the cumbersome welding process, the small contact area between the terminal and the wire, and the inability to meet high current usage scenarios.

[0007] As a preferred embodiment, the clamping portion includes a support plate and an elastic plate arranged at intervals up and down, the support plate extends outward from the welding wire portion as a whole, the elastic plate is formed by integrally bending the upper end of the welding wire portion and is located directly above the support plate, a clamping groove is formed between the support plate and the elastic plate, and the first welding end is clamped in the clamping groove by the elastic plate and the support plate.

[0008] As a preferred solution, the cross-section of the first welding end is rectangular, and is respectively fitted with the inner side walls of the clamping groove.

[0009] As a preferred solution, a connection hole is passed through the welding wire portion of two of the wiring terminals, and the connection hole is located beside the clamping portion. The second welding end of the signal line passes through the connection hole and is bent.

[0010] As a preferred solution, a protective sleeve is provided on the wire, and the protective sleeve is provided on the outer edge of the signal line and the power line, and the inner side of the protective sleeve is embedded in the insulating body, and the outer side of the protective sleeve extends outward from the insulating body.

Compared with the existing single-sided contact, the contact area is larger, so that a larger current can pass, so that it can meet the use scenario of large current.

[0028] Please refer to Figures 1 to 3 As shown, it shows the specific structure of a preferred embodiment of the utility model, which includes an insulating body 10, a terminal 20 and a wire 30.

[0029] The connection terminal 20 is provided in a plurality of configurations, and each connection terminal 20 includes an integrally formed welding wire portion 21 and a contact portion 22. The welding wire portion 21 is embedded in the insulating body 10, and the contact portion 22 extends downward from the insulating body 10. The contact portion 22 is used for contacting and conducting with the outside, and a clamping portion 23 is integrally formed outwardly on the welding wire portion 21 of two connection terminals 20; in this embodiment, the clamping portion 23 includes a support plate 231 and an elastic plate 232 arranged at intervals up and down, and the support plate 231 is formed by welding wires. The wire portion 21 extends outward as a whole, the elastic plate 232 is formed by bending the upper end of the welding wire portion 21 as a whole and is located directly above the support plate 231, and a clamping groove 201 is formed between the support plate 231 and the elastic plate 232. A connecting hole 202 is penetrated on the welding wire portion 21 of the two wiring terminals 20, and the connecting hole 202 is located beside the clamping portion 23. The lower end of the contact portion 22 is provided with a guide portion 221 that cooperates with the outside, and the guide portion 221 is used to facilitate the plug-in process of the contact portion 22 and the outside.

[0030] The wire material 30 includes two power lines 31 and a plurality of signal lines 32. One end of the power line 31 extends outward to form a first welding end 311, which is embedded in the insulating body 10 and welded with the clamping portion 23. One end of the signal line 32 extends outward to form a second welding end 321, which is embedded in the insulating body 10 and welded with the welding wire portion 21 of the corresponding terminal 20. The other ends of the power line 31 and the signal line 32 extend outward from the insulating body 10. The side of the body 10 is provided, thereby realizing the side outlet structure of the terminal block. In some scenes with small use space, the side outlet structure does not need to bend the wire, thereby avoiding damage to the terminal block structure due to bending the wire. In this embodiment, the first welding end 311 is clamped in the clamping groove 201 by the elastic plate 232 and the support plate 231. The elastic plate 232 is provided so that the clamping force on the first welding end 311 is increased by the elastic force of the elastic plate 232 during clamping, thereby preventing the first welding end 311 from being pulled out of the clamping portion 23 The first welding end 311 has a rectangular cross section, which fits the inner wall of the clamping groove 201 respectively. The rectangular setting makes the first welding end 311 not only easier to be clamped by the clamping portion 23, but also the contact area between the first welding end 311 and the clamping groove 201 is larger, further increasing the amount of current that can pass; the second welding end 321 of the signal line 32 passes through the connecting hole 202 and is bent, so as to realize the positioning between the second welding end 321 and the welding wire portion 21, which facilitates the signal line 3 2 and the welding process of the terminal block 20; the wire 30 is covered with a protective sleeve 33, which is covered on the outer edges of the signal line 32 and the power line 31, and the inner side of the protective sleeve 33 is embedded in the insulating body 10, and the outer side of the protective sleeve 33 extends outward from the insulating body 10. The protective sleeve 33 not only organizes the wire 30, collects the power line 31 and the signal line 32 together, but also prevents the wire 30 from being worn when it is bent at the connection with the insulating body 10, thereby protecting the wire 30.

[0031] The design focus of the utility model is that a clamping part is integrally formed outwardly on the welding wire part of two connecting terminals, and a first welding end is extended outwardly in cooperation with one end of the power line. The welding end is embedded in the insulating body and welded in cooperation with the clamping part, so that when the power line is welded, the first welding end can be positioned by the clamping part, so that there is no need for manual positioning and welding during the welding process, and the welding process is more convenient. At the same time, the clamping of the clamping part enables multi-faceted contact between the welding wire part and the first welding end. Compared with the existing single-sided contact, the contact area is larger, so that a larger current can pass, so that it can meet the use scenario of large current.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
