Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wiring terminals, in particular to a wiring terminal for a charging pile. Background Art
[0002] A charging station is a device that provides energy for electric vehicles, similar to a gas pump at a gas station. It can be fixed to the ground or wall and installed in public buildings (such as public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various models of electric vehicles.
[0003] When connecting the circuit board inside the charging pile to electricity, corresponding terminals are usually welded on the surface of the circuit board to connect to the wires. Currently, the terminal connected to the wire is basically equipped with a screw hole for inserting the wire core, and a screw is installed in the screw hole to lock the wire. However, the circuit board is usually equipped with multiple terminals. When the position of the terminal or the connected wire needs to be changed, the user needs to loosen the screw on the surface to remove the wire and reassemble it. The whole process is relatively cumbersome and requires tools to be prepared at all times. The terminal with this structure is very inconvenient to operate. Utility Model Content
[0004] In order to overcome the deficiencies of the existing technical solutions, the utility model provides a wiring terminal for a charging pile, which can effectively solve the technical problem that the wiring terminals in the current charging pile are inconvenient to operate.
[0005] The technical solution adopted by the utility model to solve its technical problems is:
[0006] A terminal block for a charging pile comprises a terminal outer layer and a terminal inner layer that is detachably connected to the inner side. The outer layer is provided with outer extensions extending forward on both sides of the terminal, and the inner layer is provided with inner extensions extending forward on both sides of the terminal. The inner extensions are arranged on the inner side of the outer extensions. A clamping portion protruding inward is also provided in the middle of the inner extension. The outer layer and the inner layer are evenly provided with at least two welding portions with protruding bottoms.
[0007] Furthermore, the outer layer of the terminal is provided with snap-fit holes on both sides, and the outer side of the inner layer of the terminal is provided with inverted hooks that are locked and fixed in the snap-fit holes.
[0008] Furthermore, an opening is provided on the top of the outer layer of the terminal, and an insertion rod is provided on the top of the inner layer of the terminal for protruding and inserting into the opening.
[0009] Furthermore, the outer extension portion is bent inward and then extends forward, and at least one raised ridge is provided on the outer side of the outer extension portion.
[0010] Furthermore, the front end opening of the inner extension portion expands outward.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] The utility model provides a clamping portion that can be directly clamped and fixed at one end of the wiring terminal connecting the wire. The clamping portion can directly slide in and fix the conductive column connected to the wire without the need for locking and fixing it by screws or the like.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] like Figure 1-3 As shown, the utility model provides a terminal block for a charging pile, which is mainly used as a terminal for connecting a wire to a circuit board inside the charging pile and then energizing the terminal block. The terminal block is fixed to the circuit board by welding, and then one end is extended forward to connect the wire. When in use, the terminal block needs to be used in conjunction with a conductive column that is clamped and fixed between the two terminal inner layers 2. The conductive column can be inserted and fixed in a T-shaped structure, and the end of the conductive column is connected to the conductive wire.
[0020] The specific structure of the entire terminal block mainly includes a terminal outer layer 1 and a terminal inner layer 2 that is detachably connected to the inside. The terminal inner layer 2 is tightly fixed to the inner wall when connected inside the terminal outer layer 1. When fixed, it is connected by limiting both sides and the top at the same time. Conductive clamping holes 7 are provided on both sides of the terminal outer layer 1, and a conductive opening position 9 is provided at the top position. When the terminal inner layer 2 is assembled with the terminal outer layer 1, the terminal inner layer 2 slides upward from the bottom of the terminal outer layer 1 until the inverted hooks 8 on both sides of the terminal inner layer 2 are locked in the corresponding clamping holes 7. At the same time, the insertion rod 10 on the top of the terminal inner layer 2 is inserted into the opening position 9. It is fixed by limiting at multiple angles and directions, which further strengthens the tightness and firmness between the terminal inner layer 2 and the terminal outer layer 1, and effectively prevents them from falling off.
[0021] The two sides of the inner layer 2 of the terminal are provided with inner extension parts 4 extending forward, and the middle part of the inner extension part 4 is also provided with a clamping part 5 protruding inward. The inner extension part 4 is formed by the clamping part 5 protruding in the middle to clamp and fix the conductive column sliding into the inside. The clamping part 5 has a certain elasticity, and can rebound after the conductive column slides in to prevent the conductive column from sliding out. The conductive column slides in through the clamping part 5 and is fixed at the top of the clamping part 5 through the protruding position on the top. In order to facilitate the conductive column to slide in from one end of the clamping part 5, the front end opening of the inner extension part 4 expands toward both sides.
[0022] The outer layer 1 of the terminal is provided with outer extension parts 3 extending forward on both sides, and the inner extension part 4 is provided on the inner side of the outer extension part 3. The outer extension part 3 is bent inward and also extends toward the front end, and two horizontal raised ridges 11 are provided on both sides to strengthen the firmness of the outer extension part 3 to prevent the outer extension part 3 from deforming outward. On the other hand, the outer extension part 3 on the outside also directly limits the maximum expansion range of the inner extension part 4 to prevent the inner extension part 4 from also expanding and deforming outward. At this time, the conductive column placed on the top of the inner extension part 4 can be built on the top of the outer extension part 3.
[0023] The terminal outer layer 1 and the terminal inner layer 2 are evenly provided with four bottom-raised welding parts 6, and the four welding parts 6 are distributed at the four corners, and the welding parts 6 at the same position of the terminal outer layer 1 and the terminal inner layer 2 are aligned and tightly attached to each other, and then the welding parts 6 at the four corners can be directly inserted into the charging pile circuit board and welded and fixed.
[0024] Compared with traditional technologies, this technical solution provides a clamping portion 5 that can be directly clamped and fixed at one end of the terminal connecting the wire. The clamping portion 5 can directly slide in and fix the conductive column connected to the wire without the need for locking and fixing it by screws or the like. When the user replaces the position of the conductive connection of the circuit board inside the charging pile, the conductive column can be directly slid out of the clamping portion 5, which is more convenient to operate.
[0025] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention, and any reference numerals in the claims should not be construed as limiting the claims to which they relate.
