[0021] The socket terminal structure of this embodiment is shown in FIG. Figures 1 to 3 As shown, it includes a conductive terminal 1 and a plastic shell 2. The conductive terminal 1 is provided with a plug-in end, a positioning portion 8 and a fixed end from left to right. The positioning portion 8 is a cylindrical structure. The plastic shell 2 has a cylindrical inner cavity. The inner cavity diameter of the plastic shell 2 matches the outer diameter of the positioning portion 8. When the plastic shell 2 is sleeved on the outer side of the positioning portion 8, the fit is tight.
[0022] The plug-in end is cylindrical, and its outer diameter is smaller than the outer diameter of the positioning portion 8. The right end of the plastic shell 2 is provided with a port for inserting the conductive terminal 1. A block 11 is provided on the inner circumferential wall of the plastic shell 2. An annular stopper 5 is provided at the inner left end of the plastic shell 2. An elastic positioning member is provided on the inner side of the annular stopper 5. A positioning groove 7 for positioning and cooperating with the elastic positioning member is provided on the left end surface of the positioning portion 8. A slot 13 is provided on the outer circumferential wall of the positioning portion 8, which penetrates axially along the conductive terminal 1. During the insertion of the conductive terminal 1 into the plastic shell 2, the block 11 passes through the slot 13. When the conductive terminal 1 is in place with the plastic shell 2, the left end of the positioning portion 8 abuts against the inner side of the annular stopper 5, and the elastic positioning member cooperates with the positioning groove 7. The block 11 is misaligned with the slot 13 and stops at the right end of the positioning portion 8. Specifically, the annular stopper 5 cooperates with the block 11 to form axial positioning of the positioning portion 8, and the elastic positioning member cooperates with the positioning groove 7 to form circumferential positioning.
[0023] By adopting the above structure in this embodiment, when assembling the conductive terminal 1 and the plastic shell 2, the plug-in end of the conductive terminal 1 is passed through the inner cavity of the plastic shell 2 so that the positioning part 8 is inserted into the interior of the plastic shell 2. During the plug-in process, the card block 11 passes through the positioning part 8 from the slot 13. During this process, the left end face of the positioning part 8 is squeezed against the elastic positioning member. When the card block 11 completely passes through the slot 13, the conductive terminal 1 is rotated relative to the plastic shell 2 so that the elastic positioning member and the positioning groove 7 are positioned opposite to each other and form a positioning fit. At the same time, the card block 11 abuts against the right end part of the positioning part 8. In this way, the conductive terminal 1 and the plastic shell 2 are effectively positioned and connected, and the two are reliably connected. When the elastic positioning member and the positioning groove 7 form a fit, the conductive terminal 1 can be limited from rotating relative to the plastic shell 2, so there will be no loosening problem.
[0024] In some embodiments, see Figure 2 and Figure 3 As shown, the elastic positioning member includes a rubber block 12 and a positioning column 9. An embedding groove 6 is provided on the inner side wall of the annular baffle 5. The rubber block 12 is embedded in the embedding groove 6, so that the embedding groove 6 plays a positioning role for the rubber block 12. One end of the positioning column 9 is connected to the rubber block 12, and the other end is suitable for plugging and matching with the positioning groove 7. The rubber block 12 has good elasticity and can provide a rightward elastic force for the positioning column 9, so that the end of the positioning column 9 maintains effective matching with the positioning groove 7.
[0025] In actual operation, glue can be applied on the surface of the rubber block 12, and the rubber block 12 is bonded into the embedding groove 6. In this way, after the rubber block 6 is embedded in the embedding groove 6, it is fixed by glue, which can prevent the rubber block 12 from falling out of the embedding groove 6 during the assembly of the conductive terminal 1.
[0026] In order to facilitate assembly and reduce the number of scattered parts, the rubber block 12 and the positioning column 9 are provided to be injection molded as one body, so that the structure is simple and the assembly is relatively convenient; the positioning column 9 can be a cylinder, and the positioning groove 7 is correspondingly provided as a circular groove.
[0027] Furthermore, as shown in the figure, the number of elastic positioning members in this embodiment is four, and the corresponding number of positioning grooves 7 is four. In actual operation, the elastic positioning members and the positioning grooves 7 can be set to two or three respectively; the number of card blocks 11 is four, and the corresponding number of slots 13 is four. In actual operation, the card blocks 11 and the slots 13 can be set to two or three respectively.
[0028] In some embodiments, the fixed end is a flat structure, on which is provided a fixing hole 3 that passes through the board surface, and a nut 4 is provided on one side of the fixed end at a position corresponding to the fixing hole 3. When installing the socket terminal, the mounting bolt and nut are cooperated for installation, and the external wire is fixedly connected to the fixed end to achieve electrical connection.
[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
