Description

Technical Field

[0001] This application relates to the field of battery component technology, and in particular to a thickened battery terminal block. Background Technology

[0002] Batteries typically have two terminals for connecting external wires. The wires contact the terminals via a clamping structure. Since both the clamping structure and the terminals are made of metal, their hard contact inevitably leads to friction and wear. Although they can conduct electricity, the contact area may be reduced, resulting in decreased conductivity. Existing battery terminals are usually cast in one piece, with one end outside the battery casing and the other end inside. Therefore, their size is not small, and replacing the entire terminal would be quite costly. Summary of the Invention

[0003] The purpose of this application is to provide a thickened battery terminal block with lower replacement cost.

[0004] To achieve the above objectives, this application provides a thickened battery terminal block: comprising a terminal cap and a terminal body, both of which are made of alloy material, wherein the hardness of the terminal cap is less than that of the terminal body, the terminal body includes a terminal head, the outer side of which is provided with an external thread, and the inner wall of the terminal cap is provided with an internal thread, suitable for engaging with the external thread, and fixed by tightening.

[0005] As a preferred embodiment, the top surface of the terminal head has a coaxial recessed hole, and the inner top surface of the terminal cap has a recessed post suitable for insertion into the recessed hole. The side and bottom surfaces of the recessed post are in contact with the inner wall of the recessed hole, increasing the contact area between the terminal cap and the terminal body and ensuring conductivity efficiency.

[0006] As a preferred embodiment, the outer side of the terminal cap is provided with two engaging grooves, which are symmetrical about the axis of the terminal cap, for use with pliers to facilitate the disassembly and assembly of the terminal cap.

[0007] As a preferred embodiment, the terminal cap is made of aluminum alloy, and the terminal body is made of chromium bronze, which has good conductivity and corrosion resistance. In addition, the terminal body has greater hardness, so it is not easy to wear when in contact with the terminal cap, which has less hardness.

[0008] As a preferred embodiment, the lower end of the terminal head has a terminal block, which is fixedly connected to the battery housing. The lower end of the terminal block has a terminal post, which is located inside the battery housing and is used for electrical connection with conductive components inside the battery housing.

[0009] As a preferred embodiment, the upper end face of the terminal block has a reinforcing ring surrounding the terminal head, and the lower end of the terminal cap is adapted to be embedded in the reinforcing ring, further improving the tightness of the fit between the terminal cap and the terminal body.

[0010] As a preferred embodiment, the bottom surface of the terminal block has reinforcing ribs, and there are several reinforcing ribs, all of which extend radially along the terminal block to improve the structural strength of the terminal block.

[0011] As a preferred embodiment, the terminal block has a through-side cable tray, and the outer side of the terminal block also has an anti-detachment slot to prevent the terminal body from separating from the battery casing.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing the terminal cap with low hardness to contact the metal clip of the external wire, the terminal cap can bear the pressure deformation and wear instead of the terminal body. When the terminal cap is worn to a certain extent, only the terminal cap needs to be replaced, while the terminal body can be retained for a long time, which effectively reduces the replacement cost of the battery terminal.

[0014] (2) By setting a threaded engagement structure between the terminal connector cap and the terminal head, and fixing it by tightening, the installation stability of the terminal connector cap on the terminal body is guaranteed, as well as the contact area between the terminal connector cap and the terminal body, thereby ensuring the conductivity efficiency.

[0021] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application 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. They should not be construed as limiting the specific protection scope of this application.

[0023] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0024] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0025] like Figure 1-5 The thickened battery terminal shown includes a terminal cap 1 and a terminal body 2 that can be mated together. Both the terminal cap 1 and the terminal body 2 are made of alloy materials. However, it should be noted that the hardness of the terminal cap 1 must be less than that of the terminal body 2. Therefore, the alloy materials used for the terminal cap 1 and the terminal body 2 are not the same. Generally, the terminal cap 1 can be made of aluminum alloy, which has good conductivity and corrosion resistance. The terminal body 2 is made of chromium bronze, which is the common C15100 chromium bronze material. It not only has good conductivity and corrosion resistance, but also has significantly higher hardness and better wear resistance.

[0026] The terminal body 2 includes a cylindrical terminal head 210. The outer side of the terminal head 210 is provided with an external thread 212, and the inner wall of the terminal cap 1 is provided with an internal thread 103, which fits perfectly with the external thread 212. It is fixed by tightening, which can well ensure the stable connection between the terminal cap 1 and the terminal head 210. The outer side of the terminal cap 1 is provided with a locking groove 102 for cooperating with a wire clamp. Usually, there are two locking grooves 102, and the two locking grooves 102 are symmetrical about the axis of the terminal cap 1, which facilitates the use of pliers and other pliers tools, and facilitates the disassembly and assembly of the terminal cap 1.

[0027] The top surface of the terminal head 210 has a coaxial recessed hole 211. The inner top surface of the terminal cap 1 has a recessed post 101, which is inserted into the recessed hole 211 to improve the fit between the terminal cap 1 and the terminal head 210. The side and bottom surfaces of the recessed post 101 are in contact with the inner wall of the recessed hole 211, thus increasing the contact area between the terminal cap 1 and the terminal head 210 and improving the conductivity.

[0028] The lower end of the terminal head 210 has a terminal base 220. The terminal head 210 is located in the center of the terminal base 220. The terminal base 220 is usually also circular and coaxial with the terminal head 210. The terminal base 220 is fixedly connected to the battery housing. The upper end face of the terminal base 220 has a reinforcing ring 221 to improve the structural strength of the terminal base 220. The reinforcing ring 221 surrounds the terminal head 210. After the terminal cap 1 is fully engaged with the terminal head 210, the lower end of the terminal cap 1 will be embedded in the reinforcing ring 221, further improving the fit between the terminal cap 1 and the terminal base 220. The bottom surface of the terminal base 220 has reinforcing ribs 222. The reinforcing ribs 222 protrude from the bottom surface of the terminal base 220 to fit into the groove in the battery housing mounting slot. There are several reinforcing ribs 222, all extending radially along the terminal base 220, which can effectively prevent the terminal base 220 from rotating in the battery housing mounting slot and improve the installation stability of the terminal base 220 on the battery housing.

[0029] The lower end of the terminal block 220 has a terminal post 230, which is located inside the battery housing and is used to connect the wires inside the battery. The terminal post 230 has a wire-collecting groove 213 that runs through the side. The metal end of the wire will rest in the wire-collecting groove 213 and make electrical contact with the terminal body 2. The outer side of the terminal post 230 also has an anti-detachment groove 232, which engages with the locking plate in the mounting hole of the battery housing to prevent the terminal body 2 from detaching from the battery housing.

[0030] Working principle: When in use, the terminal body 2 is fixedly connected to the battery casing, and then the wires inside the battery are connected to the terminal 230. Then, the terminal cap 1 is screwed onto the outside of the terminal head 210, and the clip of the external electrode wire is locked in the engagement groove 102 of the terminal cap 1. The clip, which is made of hard metal, will only press and wear the terminal cap 1, and the terminal body 2 will not be worn. Therefore, when the terminal cap 1 is worn to a certain extent and can no longer be used, only a new terminal cap 1 can be replaced to continue using it, which effectively reduces the replacement cost of the battery terminal.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
