Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 13A spring-loaded terminal block is shown, comprising a mounting component and a copper pin, the copper pin being axially inserted into the mounting component. It also includes a wrench 120, a spring 130, and a spring limiting component. The copper pin includes a copper pin head, a left copper pin wall 111, a right copper pin wall 112, and a copper pin groove bottom 113. The U-shaped groove formed by the left copper pin wall 111, right copper pin wall 112, and copper pin groove bottom 113 is integrally connected to the copper pin head. A left spring mounting groove 1111a and a right spring mounting groove 1121a are respectively provided on the end faces of the left copper pin wall 111 and right copper pin wall 112. The wrench 120 is groove-shaped, with a left wrench rotation shaft 128 and a right wrench rotation shaft 129 respectively provided on one end wall of each side. The wrench 120 is connected via the spring... The left rotating shaft 128 and the right rotating shaft 129 of the wrench are rotatably connected to the mounting component and installed on the radial outer layer of the copper needle; the two side walls of the wrench 120 are respectively provided with a left protrusion 126 and a right protrusion 127; the spring body 133 of the spring piece 130 is U-shaped, and the two ends of the bottom of the U-shape are respectively provided with spring piece rotating shafts 132, which are installed in the left mounting groove 1111a and the right mounting groove 1121a of the spring piece, and are rotatably connected to the copper needle; the left rotating shaft 128 and the right rotating shaft 129 of the wrench are installed in the axial direction away from the spring piece rotating shaft 132; the spring piece limiting component is detachably installed at one end of the mounting component to prevent the spring piece 130 from displacing.

[0044] In use, the spring rotating shaft 132 is placed into the spring left mounting groove 1111a and the spring right mounting groove 1121a, then the wrench left rotating shaft 128 and the wrench right rotating shaft 129 are installed into the mounting part with the slot, and finally the spring limiting member is installed on the end face of the mounting part to limit the spring 130.

[0045] Since the spring piece 130 is installed in the left mounting groove 1111a and the right mounting groove 1121a of the spring piece, it is rotatably connected to the copper needle; the wrench 120 is rotatably connected to the mounting component on the outer layer of the spring piece 130, and the left rotation shaft 128 and the right rotation shaft 129 of the wrench are axially away from the rotation shaft 132 of the spring piece; when one end of the wrench 120 is rotated outward to open, the spring piece 130, which is constrained by the abutment connection, is also opened, and the wire can be installed at this time. When the wrench 120 is pressed, the wrench 120 abuts against and constrains the spring piece 130, and the spring piece 130 presses the wire. The left protrusion 126 and the right protrusion 127 are snapped into the mounting component, and finally the wrench 120, the spring piece 130, and the wire are fixed by the left protrusion 126 and the right protrusion 127.

[0046] like Figure 2 , Figure 3 , Figure 6 , Figure 7 As shown, the spring 130 includes a U-shaped spring body 133 and a spring rotation shaft 132; one end of the spring body 133 is provided with an outwardly bent spring fixing part 131; the other end is provided with an outwardly bent spring first bending part 134; the spring first bending part 134, away from the spring body 133, is provided with an inwardly bent spring second bending part 135; the spring second bending part 135, away from the spring body 133, is provided with an inwardly bent spring second bending part 135; the spring second bending part 135, away from the spring first bending part 134, is provided with an inwardly bent spring second bending part 135. The end of the bent portion 134 is provided with the spring locking portion 136. The width of the spring locking portion 136 is greater than that of the first bent portion 134, the second bent portion 135, the spring fixing portion 131, and the spring body 133, and extends symmetrically to both sides. The spring fixing portion 131, the spring rotating shaft 132, the spring body 133, the first bent portion 134, the second bent portion 135, and the spring locking portion 136 are integrally stamped. The spring fixing portion 131 is used to fix the wire and serves to fasten the wire. The first bent portion 134 and the second bent portion 135 serve to quickly contact the wrench 120 to press the wire.

[0047] like Figure 6 , Figure 7 As shown, the wrench 120 is groove-shaped when viewed from the end face and triangular when viewed from the side. It includes a wrench body 125 in the middle and left outer side wall 121, left inner side wall 122, right outer side wall 123 and right inner side wall 124 on both sides. The left outer side wall 121 and right outer side wall 123 are respectively provided with a left protrusion 126 and a right protrusion 127 on their outer sides. The left outer side wall 121 and right outer side wall 123 are respectively provided with a left rotation shaft 128 and a right rotation shaft 129 at one end of their outer sides. The height of the right inner side wall 124 is less than the height of the right outer side wall 123, and a boss 124a is formed in the direction close to the wrench body 125. The height of the left inner sidewall 122 is less than the height of the left outer sidewall 121. A boss (not shown in the figure) symmetrical to the boss 124a is formed in the direction close to the wrench body 125. The height of the boss 124a gradually decreases in the direction close to the left rotation axis 128 and the right rotation axis 129 of the wrench. This setting is conducive to pressing the wrench 120 more smoothly.

[0048] In use, the two ends of the spring locking part 136 are respectively placed on the boss 124a and another boss symmetrical to the boss 124a; the boss 124a serves to guide and press the spring 130 with the wrench 120.

[0049] like Figure 1 As shown, the left copper needle wall 111 includes a left front copper needle wall 1111 and a left rear copper needle wall 1112, with the left front copper needle wall 1111 being higher than the left rear copper needle wall 1112; the right copper needle wall 112 includes a right front copper needle wall 1121 and a right rear copper needle wall 1122, with the right front copper needle wall 1121 being higher than the right rear copper needle wall 1122. Setting the left rear copper needle wall 1112 and right rear copper needle wall 1122 lower helps to increase the rotation range of the spring locking part 136 and increase the firmness of the wire clamping. A wire limiting part 1112a is provided in the U-shaped groove of the copper needle for limiting the wire. Specifically, the wire limiting part 1112a is punched out on the left rear copper needle wall 1112. During processing, the wire limiting part 1112a is first bent into the groove, and then part of it is bent laterally towards the bottom of the groove. The right copper needle wall 112 is provided with an outwardly extending copper needle positioning part 1122a. In use, the copper needle positioning part 1122a is inserted into the non-through groove of the mounting component to limit the copper needle to be located within the mounting component. The bottom 113 of the copper needle groove is also provided with a wire fastening part 113a for fastening the wire. It is formed by punching into the groove during processing.
