Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric vehicle battery wiring technology, specifically to a battery wiring terminal for electric vehicles. Background Technology
[0002] In the electrical system of an electric vehicle, the battery is the core power source, and the performance and reliability of its terminals are crucial. The battery terminals are responsible for connecting the battery to other electrical components of the electric vehicle and achieving stable current transmission. Their quality directly affects the electrical performance, safety and service life of the electric vehicle.
[0003] When wiring, the wires and copper plates need to be clamped together with pliers first, and then the copper plates are fixed to the battery terminals with screws using an electric screwdriver or a manual screwdriver. This wiring method requires the use of multiple tools, which is quite troublesome. Moreover, if these tools are not available, it is difficult to complete the wiring work, which makes the wiring work somewhat restrictive and highly dependent on special tools. Utility Model Content
[0004] The technical problem this invention aims to solve is that existing battery wiring structures require clamping the wires and copper plates with pliers first, and then fixing the copper plates to the battery wiring points with screws using a screwdriver. This method relies on multiple tools, is cumbersome to operate, and is difficult to complete without tools, thus having significant limitations.
[0005] To solve the above problems, the technical solution adopted by this utility model is a battery terminal for electric vehicles, including a copper sheet, one end of which is provided with a wiring structure, and the other end is provided with a connection hole, in which a connection structure is provided.
[0006] The wiring structure includes a connecting cylinder fixedly installed on the outside of the copper sheet. A threaded groove is opened on the outside of the connecting cylinder. A fastening cylinder is rotatably connected to the outside of the connecting cylinder through the thread. A pair of bent wire clamps are fixedly installed on one end of the copper sheet. The fastening cylinder is a tapered structure at one end of the bent wire clamps.
[0007] The connecting structure includes a screw, a non-metallic screw head fixed to the top of the screw, an annular groove opened below the non-metallic screw head, a sleeve slidingly disposed in the annular groove, a metal washer fixed to the bottom end of the sleeve, a limit groove opened on the side of the non-metallic screw head, and an adjusting rod slidingly disposed in the limit groove.
[0008] As a further embodiment of this utility model: an electric wire is sandwiched between a pair of curved clamping plates.
[0009] As a further embodiment of this invention, a screw is connected to the terminal block at the top of the battery to enable wire connection.
[0010] As a further embodiment of this utility model, several anti-slip grooves are provided on the outer side of the fastening cylinder to facilitate manual rotation of the fastening cylinder.
[0011] As a further embodiment of this utility model: the sleeve is set in the connecting hole of the copper sheet, and the metal washer is located below the copper sheet to prevent the non-metallic screw head from directly contacting the battery terminal and reduce the corrosion of the non-metallic screw head.
[0012] As a further embodiment of this utility model: the inner side of the fastening cylinder is closely attached to the outer edge of one end of the bent wire clamp, so that the fastening cylinder can press the bent wire clamp tightly.
[0013] Compared with the prior art, the advantages of this utility model are as follows: This application adds a novel wiring structure and connection structure. The wiring structure includes a connecting cylinder and a fastening cylinder. The fastening cylinder has a conical structure. When the bent clamping plate at one end of the copper sheet clamps the wire, the conical structure can be rotated to squeeze the bent clamping plate little by little to clamp the wire and maintain the fixing effect. The connection structure includes a non-metallic screw head and an adjusting rod, which can facilitate direct rotation of the fastening screw. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] This utility model provides a technical solution to address the existing problems mentioned in the background art.
[0023] Combined with appendix Figure 1-3 It can be seen that the device includes a copper sheet 1, one end of which is provided with a wiring structure, and the other end is provided with a connection hole 1.1, in which a connection structure is provided; the wiring structure includes a connecting cylinder 2 fixedly disposed on the outside of the copper sheet 1, the outside of the connecting cylinder 2 is provided with a threaded groove, and a fastening cylinder 3 is provided on the outside of the connecting cylinder 2 by means of a threaded rotation; the outside of the fastening cylinder 3 is provided with several anti-slip grooves 3.2, which facilitates manual rotation of the fastening cylinder 3; one end of the copper sheet 1 is fixedly provided with a pair of bent wire clamping plates 1.2, and a wire 9 is clamped in the pair of bent wire clamping plates 1.2, which facilitates fastening the wire; the fastening cylinder 3 is a tapered structure 3.1 at one end of the bent wire clamping plate 1.2, and the inner side of the fastening cylinder 3 is close to the outer edge of one end of the bent wire clamping plate 1.2, which facilitates the fastening cylinder 3 to press the bent wire clamping plate 1.2 tightly;
[0024] Combined with appendix Figure 2-4 It can be seen that the connection structure includes a screw 4, which is connected to the terminal at the top of the battery 10 to realize the wiring of the wire 9. A non-metallic screw head 5 is fixed at the top of the screw 4. An annular groove 5.1 is opened below the non-metallic screw head 5. A sleeve 6 is slidably provided in the annular groove 5.1. A metal washer 7 is fixed at the bottom of the sleeve 6. The sleeve 6 is set in the connection hole 1.1 of the copper sheet 1. The metal washer 7 is located below the copper sheet 1 to prevent the non-metallic screw head 5 from directly contacting the terminal of the battery 10 and to reduce the corrosion of the non-metallic screw head 5. A limiting groove 5.2 is opened on the side of the non-metallic screw head 5. An adjusting rod 8 is slidably provided in the limiting groove 5.2.
[0025] The working principle of this utility model is as follows: When wiring the battery, first pass one end of the wire 9 through the fastening cylinder 3 and insert it into a pair of curved clamping plates 1.2. Then rotate the fastening cylinder 3 so that the conical structure 3.1 continuously squeezes the pair of curved clamping plates 1.2, so that the wire 9 is pressed tightly, which facilitates the fastening connection.
