[0026] In the following description, the content of the specification drawings does not represent the dimensional relationship of specific components. Terms such as "connection" and "structure" are interpreted in a broad sense. Without special instructions, the so-called connection includes both direct connection and indirect connection.
[0027] Next, according to the foregoing technical solution, the content of the present invention will be further described in combination with specific embodiments. The following embodiments of this technical solution do not mean that this technical solution can only be implemented with this embodiment.
[0028] As Figure 3 shown, a terminal includes a housing 1 and a hardware part 2 placed in the housing 1. The number of the hardware parts 2 can be 1, two or more. In this embodiment, the number of the hardware parts 2 is 4. Four corresponding cavities are provided in the housing 1 for accommodating and installing the hardware part 2. The four cavities can communicate with each other or be separated by structures such as partitions or flanges.
[0029] The hardware part 2 includes a first terminal 21 and a second terminal 22 which are connected to each other. Specifically, a connecting piece 23 is provided between the first terminal 21 and the second terminal 22 and they are electrically connected through the connecting piece 23.
[0030] As Figure 1 、 2As shown in FIGS. 10, the first terminal 21 includes an upper connecting piece 211, a lower connecting piece 212, a side wall 213 and a resilient piece 214. The upper connecting piece 211 and the lower connecting piece 212 are respectively connected to the upper and lower ends of the side wall 213, and the upper connecting piece 211 and the lower connecting piece 212 are opposite to each other in the vertical direction. The resilient piece 214 is disposed between the upper connecting piece 211 and the lower connecting piece 212. The resilient piece 214 is a pressing type resilient piece and is in an oblique angle shape. The lower end of the resilient piece 214 is fixedly connected to the lower connecting piece 212, such as by snap connection or welding. Of course, the so-called fixed connection also includes integrally formed, that is, the lower end of the resilient piece 214 can also be integrally formed with the lower connecting piece 212. The upper end of the resilient piece 214 abuts against the upper connecting piece 213, and an insertion wire inlet 24 is formed between the upper end of the resilient piece 214 and the upper connecting piece 211. The upper connecting piece 211 is provided with a wire withdrawal hole 215, and the upper end of the resilient piece 214 abuts against the wire withdrawal hole 215 of the upper connecting piece. The wire withdrawal hole 215 is preferably rectangular. The upper end of the resilient piece 214 protrudes outward to form a protruding portion, so that the upper end of the resilient piece 214 is similar to a convex shape, and the protruding portion extends into the wire withdrawal hole 215. A stop piece 216 for preventing the wire 3 from being inserted excessively is provided between the first terminal 21 and the second terminal 22. The stop piece 216 is disposed on the upper connecting piece 211 on the side opposite to the insertion wire inlet 24, that is, the side of the upper connecting piece 211 opposite to the insertion wire inlet 24 extends downward to form the stop piece 216, so as to prevent the wire 3 from connecting from the first terminal to the second terminal 22. As an alternative, the stop piece 216 can also be disposed on the side wall 213 or other components. Even the stop piece 216 can be constituted by a convex structure formed on the inner surface of the cavity of the housing 1, such as a convex structure formed by the upper surface of the cavity protruding downward. This convex structure can not only limit the hardware 2, but also prevent the wire 3 from being inserted excessively.
[0031] The second terminal 22 includes a bottom plate 221 and main clamping pieces 222 extending outward from both sides of the bottom plate 221. The connecting piece 23 is fixedly connected to the bottom plate 221 and the lower connecting piece 212. Preferably, the connecting piece 23 is integrally formed with the bottom plate 221 and the lower connecting piece 212. The bottom plate 221 and the lower connecting piece 212 are at different horizontal heights, and the horizontal position of the lower connecting piece 212 is higher than the horizontal position of the bottom plate 221, so that the height of the first terminal 21 is less than that of the second terminal 22. This structure can ensure that the resilient piece 214 can obtain a greater elastic deformation and ensure that there is sufficient elastic force to clamp the wire 3. Therefore, the connecting piece 23 is inclined.
[0032] The upper end of the main clamping piece 222 first bends inward and then expands outward from bottom to top to form a first insertion interface 223 with an upward opening for inserting the wire. A side clamping piece 224 extending transversely is further provided on the side of the upper end of the main clamping piece 222. The opening of the side clamping piece 224 bends inward and then expands outward to form a second insertion interface 225 with an opening facing the side. The first insertion interface 223 and the second insertion interface 225 are respectively in the vertical direction.
[0033] A hollow portion 226 is provided at the first insertion interface 223 and / or the second insertion interface 225. The hollow portion 226 is used to clamp and fix a cylindrical wire to prevent the wire from detaching from the first insertion interface 223 and / or the second insertion interface 225. Preferably, the hollow portion 226 is at the inwardly curved part of the first insertion interface 223 and / or the second insertion interface 225.
[0034] The housing 1 is fixedly connected by a main body 11 and a front cover 12. The main body 11 and the front cover 12 enclose a cavity for accommodating and installing the hardware 2. An opening is provided at the front end of the main body 11. The hardware 2 is accommodated in the cavity through the opening. The front cover 12 is used to block the opening of the main body 11. The main body 11 and the front cover 12 can be connected by snap connection, bonding or other fixing methods. A pressing button 14 is provided on the housing 1. Preferably, the pressing button 14 is integrally formed with the front cover 12. The housing 1 is respectively provided with housing through holes at positions corresponding to the first insertion interface 223, the second insertion interface 225 and the wire withdrawal hole 215. Among them, the first through hole 121 corresponds to the first insertion interface 223, the second through hole 122 corresponds to the second insertion interface 225, and the third through hole 123 corresponds to the wire withdrawal hole 215. Since the terminal of this embodiment includes 4 pieces of hardware 2, correspondingly, the numbers of the first through hole 121, the second through hole 122 and the first through hole 123 are all 4. The first through hole 121 is provided on the upper wall of the front cover 12, the second through hole 122 is provided on the side wall of the front cover 12, and the third through hole 123 is provided on the upper surface of the main body.
[0035] A pressing block 13 capable of extending into the wire withdrawal hole 215 and pressing the elastic piece 214 is provided on the pressing button 14. When the pressing button 14 is pressed downward, the pressing block 13 on the pressing button 14 presses the upper end of the elastic piece 214 downward to make it move downward and open the wire insertion port 24. When the wire extends into the wire insertion port 24 and then the pressing button 14 is released, the elastic piece 214 tightly presses the wire between the elastic piece 214 and the upper connecting piece 211 by its own elasticity.
[0036] Such as Figures 4 to 9As shown, the terminal block is further provided with a plug board 3. The plug board 3 includes a base 31 and pins 32 fixed on the base 31. The number of the pins 32 is the same as that of the hardware parts 2, and the positions of the pins 32 correspond to the positions of the first through holes 121 and the second through holes 122. The pins 32 can be flat pins or cylindrical pins. In order to strengthen the fixation of the pins 32, longitudinal ribs 33 extending along the length direction of the base 31 are further provided on the base 31, and transverse ribs 34 extending along the width direction of the base 31 are also provided at the installation positions of the pins 32. The pins 32 include a first end 321 and a second end 322. The first end 321 can pass through the first through hole 121 or the second through hole 122 and be electrically connected to the first socket 223 or the second socket 225, and the second end 322 passes through the base 31 for connecting a wire.
[0037] In order to strengthen the connection between the plug board 3 and the housing 1, a recess 15 is provided at the position where the first through hole 121 and / or the second through hole 122 is / are provided on the housing 1. The plug board 3 can be inserted into the recess 15. The recess 15 can not only strengthen the fixed connection between the plug board 3 and the housing 1, but also play a role in hiding the plug board 3.
[0038] The technical effects of this improved embodiment are also similar to those of the foregoing embodiments. On the premise of enhancing the electrical connection safety level, improving the production efficiency, and increasing the maintenance convenience, the number of metal wires that can be accessed is further increased, and it can be more flexibly applied in various scenarios.
[0039] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them, and all technical features can be combined according to actual situations. The content of the technical solutions of the present invention modified or equivalently replaced by those skilled in the art, such as replacing a straight line or a plane with a curve or a curved surface in terms of shape, changing the dimensional ratio relationship of components, simply replacing the spatial position of components, and simply replacing materials, etc., should all be covered within the scope of the claims of the present invention.
