[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0025] See Figures 1 to 4 As shown, a conductive spring and a coupler are disclosed. The coupler includes a lower coupling seat 1, on which several concentric coupling protrusions 2 of different diameters are provided, and several insertion slots 201 are formed between the coupling protrusions 2 at intervals. Several pairs of conductive springs 3 are connected to the lower coupling seat 1.
[0026] The conductive spring 3 includes a fixing part 4, on which a connecting hole 401 is provided. The lower coupling seat 1 has a threaded hole corresponding to the connecting hole 401. By passing a screw through the connecting hole 401 and the threaded hole, the fixing part 4 of the conductive spring 3 is fastened to the lower coupling seat 1.
[0027] One side of the fixing part 4 is bent along the first direction to form an integral free terminal 5. The free terminal 5 is elastically disposed in the insertion groove 201 and its contact end is fixed with a contact point 501.
[0028] The other end of the fixing part 4 is bent along the second direction to form an integrally formed connecting terminal 6. The connecting terminal 6 extends out of the lower coupling seat 1. Several pairs of crimping claws 7 extend along the length direction from the side of the connecting terminal 6.
[0029] This coupler features a well-designed and ingeniously constructed conductive spring 3, which allows for the direct riveting of high-voltage and / or low-voltage wires to the coupler. This reduces the overall product assembly process and the number of parts, lowers material costs, improves production efficiency, and enables the coupler to be assembled on a fully automated production line.
[0030] The plurality of wire clamping claws 7 include at least one pair of clamping plates 71 for clamping wires and one pair of contact plates 72 for clamping wire cores. The pair of clamping plates 71 are disposed in front of the connecting terminal 6, and the pair of contact plates 72 are disposed behind the connecting terminal 6.
[0031] During production, the open end of the wire is placed on the connecting terminal 6. Then, the clamping plate 71 and the contact plate 72 are riveted to bend the left and right parts in sequence. The clamping plate 71 presses the wire onto the connecting terminal 6, while the contact plate 72 presses the wire core part of the wire. At the same time, the connecting terminal 6 and the wire core are electrically connected, thereby achieving that the wire, the wire core and the connecting terminal 6 are tightly fixed to each other.
[0032] The extension length H1 of the clamping plate 71 is greater than the extension length H2 of the contact plate 72. This structure is designed because the wire has an outer insulating sleeve, so its diameter is larger than that of the wire core. Therefore, the longer clamping plate 71 can increase the contact area and make the wire more securely fixed.
[0033] The two sides of the connecting terminal 6 are bent in the opposite direction to the free terminal 5 to form reinforcing flanges 8. The plurality of pairs of wire clamping claws 7 are integrally formed on the reinforcing flanges 8. The reinforcing flanges 8 can increase the strength of the connecting terminal 6 and prevent the single-piece connecting terminal 6 from bending or deforming when subjected to external force.
[0034] The connecting terminal 6 extends at an angle relative to the fixing part 4; and a reinforcing convex surface 9 is stamped at the joint position between the connecting terminal 6 and the fixing part 4; the reinforcing convex surface 9 can increase the connection strength between the connecting terminal 6 and the fixing part 4, so that the connecting terminal 6 and the fixing part 4 maintain a stable included angle, and will not be easily bent or deformed due to external impact.
[0035] On the coupler, there are at least a plurality of conductive springs 3, including two conductive springs 3 for connecting to high voltage; the connecting terminal 6 of the conductive spring (marked as 3A in the figure) includes at least a high voltage riveting section 61, the width of the high voltage riveting section 61 decreasing linearly from front to back, and the clamping piece 71 and the contact piece 72 are arranged on the high voltage riveting section 61.
[0036] The high-voltage riveting section 61 can be installed flat and has a relatively wide overall width, making it suitable for connecting high-voltage wires with a large wire width (0.75 square millimeters). This allows the high-voltage riveting section 61 to directly rivet the wires, and also allows the wires with terminals on their open ends to be directly inserted into the high-voltage riveting section 61 for installation.
[0037] The coupler also includes at least two conductive springs 3 for connecting low voltage; the connecting terminal 6 of the conductive spring (marked as 3B in the figure) includes at least a low voltage riveting section 62, the width of which increases linearly from front to back, and the clamping piece 71 and the contact piece 72 are arranged on the low voltage riveting section 62.
[0038] The low-voltage riveting section 62 is curved and has a narrow overall width, making it suitable for connecting low-voltage wires with a small wire width (0.3 square millimeters). The narrower low-voltage riveting section 62 can make the low-voltage wires connect firmly, reduce the space that can be moved, and make the connection more stable after riveting.
[0039] Furthermore, the conductive spring 3 connecting high voltage and low voltage have certain structural differences, which helps production personnel to identify the connection positions of low voltage and high voltage, improves wiring efficiency, and reduces the occurrence of wires being placed in the wrong position.
[0040] The outer surface of the connecting terminal 6 has several equally spaced grooves 10 arranged sequentially along its length. The two ends of the grooves 10 extend to the outer surface of the contact pieces 72 on both sides. The grooves 10 can release residual stress during processing, ensuring that the contact pieces 72 on both sides do not spring back after manufacturing and processing, and ensuring that the contact pieces 72 and the wire core have sufficient contact area, thereby reducing the resistance of incomplete connection.
[0041] See Figure 5 As shown, the plurality of pairs of conductive springs 3 are spaced apart from each other, and each connecting terminal 6 extends in the same direction; by arranging the conductive springs 3, which have both strong and weak electrical connections, in the same direction, the coupler can be used to perform wiring procedures on fully automated production equipment.
[0042] In addition, there is a conductive spring 3 for connecting the ground wire, and the connection terminal 6 of the conductive spring (marked as 3C in the figure) can be a conventional structure or the structure with the above-mentioned clamping claw 7; and the conductive spring 3 is connected to the outermost side of the coupler and extends in a different direction than the other connection terminals 6; which also helps production personnel to identify the ground wire connection position.
[0043] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
