[0027] The utility model provides a square cap patch wire-wound resistor, wherein an elastic member is arranged to clamp a clamping block in a clamping groove of a positioning plate by utilizing its elasticity, so that the positioning plate is installed in a placement groove of a fixing frame, and then the wire-wound resistor body is installed on the fixing frame, and the positioning plate can be released from the limit by pulling a pull rod at a later stage, so that it is convenient to quickly disassemble, assemble and overhaul the resistor.

[0028] Figure 1-Figure 4 The structure diagram of a square cap chip winding resistor of the present invention is shown in FIG. Figure 1-Figure 4 In this embodiment, a square cap chip wound resistor has a main body including a resistor component 100 and a connection component 200 .

[0029] The resistor assembly 100 includes a wire-wound resistor body 110 and a fixing frame 120 disposed at both ends of the wire-wound resistor body 110. Positioning plates 111 are disposed at both ends of the wire-wound resistor body 110. A placement groove is provided on the inner side of the fixing frame 120. The positioning plate 111 is disposed in the placement groove. A clamping groove is provided at the upper end of the positioning plate 111. Preferably, in this embodiment, a bolt 121 is disposed on the fixing frame 120. The bolt 121 penetrates the fixing frame 120. The bolt 121 disposed on the fixing frame 120 and penetrates the fixing frame 120 can fix the fixing frame 120 at a designated position, thereby ensuring the stable placement of the entire wire-wound resistor. A clamping column 122 is vertically disposed on one side wall of the fixing frame 120. A clamping groove 123 is disposed on the other side wall of the fixing frame 120. The clamping column 122 and the clamping groove 123 are adapted in size. Adjacent fixing frames 120 can be connected under the action of the clamping column 122 and the clamping groove 123. When a plurality of wire-wound resistors are transported, adjacent wire-wound resistors can be clamped together to ensure stability during transportation. The side wall of each fixing frame 120 is provided with two clamping columns 122. The two clamping columns 122 further enhance the stable clamping between adjacent wire-wound resistors. The clamping columns 122 are threadedly mounted on the side wall of the fixing frame 120. The clamping columns 122 are threadedly mounted on the side wall of the fixing frame 120. Later, the operator can manually rotate the clamping columns 122 to remove them from the side wall of the fixing frame 120 so as to disassemble and replace the clamping columns 122.

[0030] The connecting assembly 200 includes an elastic member 210 disposed inside the fixing frame 120, a clamping block 220 fixed at the lower end of the elastic member 210, and a pull rod 230 fixed at the middle of the upper end of the clamping block 220 and located inside the elastic member 210. The pull rod 230 penetrates the fixing frame 120, and the clamping block 220 is clamped in the clamping groove. Preferably, in this embodiment, a first magnet is disposed at the lower end of the clamping block 220, and a second magnet is disposed in the clamping groove of the positioning plate 111. The first magnet and the second magnet are magnets of opposite polarity. The first magnet and the second magnet disposed in the clamping groove of the clamping block 220 and the positioning plate 111 can firmly absorb the clamping block 220 in the clamping groove of the positioning plate 111, further ensuring that the wire wound resistor body 110 is stably mounted on the fixing frame 120.

[0031] Combination Figure 1-Figure 4, a square cap chip wound resistor of the present embodiment is specifically used as follows: the operator places the positioning plates 111 at both ends of the wound resistor body 110 in the placement grooves of the fixing frame 120, and under the elastic action of the elastic member 210, the clamping block 220 is clamped into the clamping groove of the positioning plate 111, and then the positioning plate 111 is clamped into the placement groove of the fixing frame 120, so that the entire wound resistor body 110 is installed on the fixing frame 120. Later, when disassembling and repairing, the operator manually pulls up the pull rod 230 to drive the clamping block 220 to move upward and compress the elastic member 210, thereby releasing the limit of the clamping block 220 on the positioning plate 111, and then facilitating the rapid removal of the wound resistor body 110 from the fixing frame 120, so as to quickly disassemble and repair it.
