DETAILED DESCRIPTION
[0026] See attached Figures 1 to 7The utility model discloses a grounding terminal assembly of a European-style socket, including a grounding electrode socket 1 and a fixed wire terminal structure. The grounding electrode socket 1 includes a middle conductive strip 11, and the two ends of the middle conductive strip 11 are bent upward to form electrode feet 12. The fixed wire terminal structure includes a conductive frame 2, and the conductive frame 2 includes a bottom plate 21. The bottom plate 21 has side plates 22 that are turned upward and extended on both sides. The bottom plate 21 and the two side plates 22 form a receiving cavity. The receiving cavity has a top opening and a front wire insertion opening. The middle conductive strip 11 is fixedly connected to the top of the conductive frame and covers the top opening of the receiving cavity. The middle conductive strip 11 is provided with a relief opening leading to the receiving cavity. Hole 110, a spring clip 3 is provided in the accommodating cavity, the spring clip 3 includes a positioning portion 31, the positioning portion 31 is fixed on the bottom plate 21, the front end of the positioning portion 31 is flipped and extended with a spring bow portion 32, the spring bow portion 32 extends with an elastically swingable clamping piece 33, the clamping piece 33 is extended toward the middle conductive bar 11 and obliquely extends to the rear, the free end of the clamping piece 33 has a retaining clamping end 331, the retaining clamping end 331 corresponds to the wall of the middle conductive bar 11 to form an elastic clamping mouth, the clamping piece 33 has a contact portion 332 for contacting and pressing to drive the clamping piece 33 to elastically deform, and the contact portion 332 corresponds to the position of the avoidance hole 110. When installing the wire, the wire is inserted along the front wire insertion opening and pushes against the wire clamp body 33. The wire is pressed against the middle conductive bar wall of the grounding electrode socket through the retaining wire clamp end, completing the clamping and fixing of the wire. When removing, the wire is passed through the avoidance hole to touch the contact portion 332 of the wire clamp body 33. The wire clamp body 33 deforms to loosen the wire, and the wire can be pulled out, thus achieving convenient and quick disassembly and assembly of the wire. The middle conductive bar of the grounding electrode socket covers the upper end of the conductive frame. The middle conductive bar cooperates with the spring clamp 3 to clamp and fix the wire, achieving a more compact structural arrangement. In addition, under the above connection, the wire is released by passing through the avoidance hole of the middle conductive bar to touch the contact portion 332 to press the wire clamp body 33, thereby facilitating the operation in the forward direction of the European socket to loosen the wire.
[0027] To facilitate smoother wire insertion and removal, the bottom of the middle conductive bar 11 is recessed with a wire guide groove 111, extending along the length of the middle conductive bar 11. The retaining clamp 331 corresponds to the position of the wire guide groove 111 and cooperates with the wall of the groove 111 to form the elastic wire clamping opening. Accordingly, since the depth of the wire guide groove formed on the middle conductive bar 11 is limited, the end of the retaining clamp 331 is provided with an arc-shaped notch 3311 that mates with the wire guide groove 111 to more smoothly push open the elastic wire clamping opening during wire insertion. This also ensures more reliable positioning and fixation of the wire.
[0028] As an embodiment of the present utility model, the front end edge of the bottom plate 21 is flipped and extended to form a front end plate 23, which includes a main board body 231 connected to the bottom plate 21, and the upper part of the main board body 231 is folded 90° toward the inner side of the conductive frame 2 to form a folded wing plate 232. After the folded wing plate 232 is folded, the front end wire insertion opening is formed on the upper part of the main board body 231, and a gap corresponding to the front end wire insertion opening is formed between one side of the folded wing plate 232 and the side plate 22. The spring bow portion 32 of the spring clip 3 is placed in the space between the bottom of the folded wing plate 232 and the bottom plate 21, and the middle conductive strip 11 is supported on the folded wing plate 232. The front end plate and its upper folded wing plate 232 support the middle position of the middle conductive bar 11, keeping the grounding electrode sleeve and the conductive frame 2 more reliably installed; the folded wing plate 232 and the main body limit the position of the spring clip 3; the folded wing plate 232 cooperates with the side plate 22 to form a certain limit guide for the insertion of the wire.
[0029] At the same time, based on the effective support formed in the middle of the middle conductive bar 11, protruding clips 112 can be used on both lateral sides of the middle conductive bar 11, and clip holes 221 are provided on the side panels 22. The middle conductive bar 11 is inserted between the two side panels 22, and the clips 112 are clipped into the clip holes 221 of the side panels. This achieves the middle conductive bar 11 and the side panels 22 being fixed to the middle conductive bar through the clips of the clips and the clip holes. The middle conductive bar 11 and the conductive frame 2 are firmly and reliably fixed, and the structure is simple and easy to assemble. To make the grounding plug sleeve more stable and prevent the grounding plug sleeve from tilting and swinging when the wire is pushed in and out, at least two clip holes 221 are arranged on the single side panel 22 along the length of the middle conductive bar 11. Corresponding clips 112 are provided along the middle conductive bar 11, corresponding to the clip holes 221. This achieves a more balanced and stable installation of the grounding plug sleeve.
[0030] Furthermore, symmetrically arranged on either side of the main body 231 are two folding wings 232, spaced apart from each other, thereby forming a central strip connecting the two folding wings 232 on the main body 231. The design of two spaced folding wings 232 provides more stable and reliable support and electrical connection for the central conductive strip 11. Simultaneously, the two folding wings 232 can correspond one-to-one with the two side panels 22 to form two gaps, thereby utilizing the two gaps to form two wire insertion channels. Therefore, an optimized design is employed: a dividing groove is provided in the spring clamp 3, one end of which extends from the spring bow portion 32 through the free end of the clamp body 33, thereby forming two clamp units within the clamp body 33. Each clamp unit has a retaining end 331 and a contact portion 332. The retaining end 331 of each clamp unit corresponds to the gap between the folding wing 232 and the side panel 22 adjacent to the folding wing 232. This forms two positions for wire insertion to facilitate wiring operations. Therefore, the wire guiding grooves on the middle conductive bar 11 are also designed to be two.
[0031] As another embodiment of the present invention, Figure 1 as well as Figures 4-7 As shown, a positioning boss 2311 is protruded from the top of the middle strip, and a positioning through hole 113 is provided on the middle conductive strip 11. The positioning boss 2311 is inserted into the positioning through hole 113, so as to form a more reliable positioning for the middle conductive strip 11.
[0032] A rib 2312 is stamped on the main body 231 to extend in the height direction and protrude toward the inner side of the conductive frame 2. The rib 2312 serves to strengthen the main body, but more importantly, the rib 2312 protrudes from the edge of the positioning hole 113, and the middle conductive bar 11 is supported on the top of the rib 2312. The rib provides further support for the middle conductive bar.
[0033] This utility model provides a grounding plug sleeve and spring-type terminal structure combination scheme, which realizes the elastic clamping and fixing of external wires on the socket, making the socket wiring operation more convenient. At the same time, the structural design of the front end plate realizes the reliable positioning of the spring clip and the reliable support and electrical connection of the grounding plug sleeve.
