[0041] The closed terminal support structure 2 of the utility model embodiment is applied to the connector 1, and the first fixed support 10 is used to stably fix the first contact terminal 3. The tongue plate part 12 of the first fixed support 10 is located in the insertion cavity of the insulating body and extends along the horizontal direction, which can effectively fix one end of the first contact terminal 3. Meanwhile, the first extension part 13 is connected with the tongue plate part 12 through the connecting part 14 and extends along the vertical direction of the connector 1, further fixing the other end of the first contact terminal 3. This structure not only improves the stability and reliability of the connector 1, but also ensures that the first contact terminal 3 is not easy to loosen or fall off during long-term use, thereby improving the electrical connection performance and signal transmission quality of the connector 1. In addition, the plurality of interval first clamping slots 11 can embed a plurality of first contact terminals 3 at the same time, meet the high-density and small-size requirements of the connector 1, and improve the integration and use convenience of the connector 1.

[0042] Specifically, the connector 1 comprises an insulating body and a first contact terminal 3, wherein the insulating body is used to provide support and protection, and the first contact terminal 3 is used to realize electrical connection and signal transmission. The closed terminal support structure 2 mainly comprises a first fixed support 10. The first fixed support 10 is installed in the insulating body and is designed with a plurality of first clamping grooves 11 arranged at intervals. These first clamping grooves 11 are specially used to embed the first contact terminal 3, so as to ensure that they can be stably fixed in the connector 1. The first fixed support 10 specifically comprises a tongue plate part 12, a connecting part 14 and a first extension part 13. The tongue plate part 12 is located in the insertion cavity of the insulating body and extends along the horizontal direction of the insertion cavity. The tongue plate part 12 is provided with a groove or a hole position matched with the first contact terminal 3, which is used to fix one end of the first contact terminal 3. The connecting part 14 is connected at one end of the tongue plate part 12 and plays a transition and connection role.

The first extension part 13 is also provided with a corresponding fixing structure for fixing the other end of the first contact terminal 3.

[0043] In actual application, when it is needed to install the first contact terminal 3 into the connector 1, only one end of the first contact terminal 3 needs to be embedded into the groove or hole position of the tongue plate part 12, and then the other end is fixed on the fixing structure of the first extension part 13. This structure not only has convenient installation, but also can ensure the stability and reliability of the first contact terminal 3 in the connector 1.

[0044] Therefore, it can be understood that the closed terminal support structure 2 according to the embodiment of the utility model has at least the following beneficial effects: the first clamping groove 11 formed by the tongue plate part 12, the connecting part 14 and the first extension part 13 connected in sequence can wrap and embed the first contact terminal 3, so as to better prevent the circuit short circuit caused by the metal waste falling into in the production process, and further improve the reliability and safety of the connector 1.

[0045] Reference Figures 3 to 6In some embodiments of the utility model, the connector 1 further comprises a second contact terminal 4, the closed terminal support structure 2 further comprises a second fixed support 20, the second fixed support 20 is installed in the insulating body of the connector 1, the second fixed support 20 is provided with a plurality of interval arranged second clamping slots 21, and the second clamping slot 21 is used for embedding the second contact terminal 4. The embodiment further provides the connector 1 comprising the second contact terminal 4 and the corresponding second fixed support 20 thereof. In order to meet the fixing demand of different contact terminals in the connector 1, ensure that the connector 1 can stably and reliably work, the second fixed support 20 is additionally arranged in the insulating body of the connector 1. The second fixed support 20 is similar to the first fixed support 10 and is also installed in the insulating body. The second fixed support 20 is provided with a plurality of interval arranged second clamping slots 21, and these second clamping slots 21 are specially used for embedding and fixing the second contact terminal 4. The design of the second clamping slot 21 fully considers the shape and size of the second contact terminal 4, so as to ensure that it can be closely and stably embedded in the second clamping slot 21 and will not be loose or fall off in the working process of the connector 1.

[0046] In actual application, when the second contact terminal 4 needs to be installed into the connector 1, the operator only needs to align the second contact terminal 4 with the entrance of the second clamping slot 21 and then push it gently. The internal structure of the second clamping slot 21 will tightly wrap the second contact terminal 4, ensuring that it can maintain a stable position and state in the use process.

[0047] Further, refer to Figures 4 to 6 In some embodiments of the utility model, the second fixed support 20 comprises a fixed part 22 and a second extension part 23. The fixed part 22 is arranged above the connecting part 14, the fixed part 22 extends along the horizontal direction of the insertion cavity, and the fixed part 22 is used for fixing one end of the second contact terminal 4; the second extension part 23 is arranged at the rear side of the first extension part 13 and connected with one end of the fixed part 22, the second extension part 23 extends along the vertical direction of the connector 1, and the second extension part 23 is used for fixing the other end of the second contact terminal 4, and the fixed part 22 and the second extension part 23 are sequentially connected to form the second clamping slot 21.

[0048] In order to meet the stable fixing requirement of the second contact terminal 4 in the connector 1, the second fixing support 20 is designed to include a fixing part 22 and a second extending part 23. The fixing part 22, as the main component of the second fixing support 20, is arranged above the connecting part 14 and extends along the horizontal direction of the insertion cavity. The design position of the fixing part 22 enables it to effectively fix one end of the second contact terminal 4 and ensures that the second contact terminal 4 cannot move or loosen in the horizontal direction. The internal structure of the fixing part 22 is matched with the shape of the second contact terminal 4, so that the second contact terminal 4 can be closely embedded therein. The second extending part 23 is arranged at the rear side of the first extending part 13 and is connected with one end of the fixing part 22. The second extending part 23 extends along the vertical direction of the connector 1 and provides stable fixing support for the other end of the second contact terminal 4. Through the sequential connection of the fixing part 22 and the second extending part 23, the second clamping groove 21 for embedding and fixing the second contact terminal 4 is formed. This design not only ensures the stability of the second contact terminal 4 in the connector 1, but also improves the overall structural strength of the connector 1.

[0049] In actual application, when the second contact terminal 4 needs to be installed into the connector 1, the operator will first embed one end of the second contact terminal 4 into the fixing part 22 and then fix the other end of the second contact terminal 4 on the second extending part 23. This installation method is simple and easy to operate and can ensure the stability and reliability of the second contact terminal 4 in the connector 1.

[0050] Further, with reference to Figures 4 to 6 In some embodiments of the utility model, the first fixing support 10 can be clamped in the second fixing support 20, the rear end of the first extending part 13 is provided with a plurality of clamping grooves 131, the clamping grooves 131 are arranged in the width direction of the first extending part 13, the front end of the second extending part 23 is provided with a plurality of clamping parts 231, and the clamping parts 231 can be clamped in the clamping grooves 131.

[0051] In order to realize the stable connection of the first fixed support 10 and the second fixed support 20, a plurality of clamping grooves 131 are arranged at the rear end of the first extension part 13. These clamping grooves 131 are arranged along the width direction of the first extension part 13, providing accurate clamping positions for the second fixed support 20. The design of the clamping grooves 131 not only considers the structural strength, but also ensures the smoothness and stability of the clamping process. Correspondingly, a plurality of clamping parts 231 are arranged at the front end of the second extension part 23. These clamping parts 231 are matched in shape and size with the clamping grooves 131, and can be tightly clamped in the clamping grooves 131. When the first fixed support 10 and the second fixed support 20 need to be connected, the operator only needs to align the clamping parts 231 of the second extension part 23 with the clamping grooves 131 of the first extension part 13, and then gently push them in to realize clamping. Through this clamping structure, the first fixed support 10 and the second fixed support 20 can be tightly connected together to form a stable whole. This connection method not only improves the structural strength of the connector 1, but also ensures the stability and reliability of the first contact terminal 3 and the second contact terminal 4 in the connector 1. At the same time, the design of the clamping structure also facilitates the production and assembly of the connector 1, improving the production efficiency and quality.

[0052] Further, with reference to Figures 4 to 6 In some embodiments of the present application, the front end of the second extension part 23 is also provided with a top abutting part 232, and the position of the top abutting part 232 corresponds to the position of the first clamping groove 11 one by one, and the top abutting part 232 is clamped in the first clamping groove 11.

[0053] Specifically, the top abutting part 232 is arranged at the front end of the second extension part 23, which not only enhances the structural strength of the second extension part 23, but also realizes accurate clamping with the first clamping groove 11. The top abutting part 232 is carefully designed and positioned, so that its position corresponds to the position of the first clamping groove 11 one by one. When the second fixed support 20 is assembled with the first fixed support 10, the top abutting part 232 can be accurately clamped into the first clamping groove 11 to form a stable connection. This clamping method not only ensures the stable fixation of the second fixed support 20 on the first fixed support 10, but also improves the structural strength and stability of the entire closed terminal support structure 2. The shape and size of the top abutting part 232 are matched with the first clamping groove 11 to ensure the smoothness and tightness of the clamping process. At the same time, the material selection of the top abutting part 232 also considers wear resistance and aging resistance to ensure that it can maintain a stable clamping state in the long-term use process.

[0054] In practical applications, the arrangement of the abutting portion 232 enables the second fixed support 20 to be more firmly fixed on the first fixed support 10, thereby enhancing the stability and reliability of the connector 1 as a whole. No matter in the process of plugging or in the process of bearing external force, the abutting portion 232 can effectively prevent the second fixed support 20 from loosening or falling off, and meanwhile, the first contact terminal 3 can be limited in the first clamping slot 11 through the abutting portion 232.

[0055] With reference to Figures 4 to 6 In some embodiments of the utility model, the top end of the first extension 13 is provided with an avoiding slot 132, and the upper end of the second extension 23 is provided with a clamping block 233. When the first fixed support 10 is clamped below the second fixed support 20, the clamping block 233 is clamped in the avoiding slot 132.

[0056] In order to realize the stable connection between the first extension 13 and the second extension 23, the top end of the first extension 13 is provided with the avoiding slot 132 in the embodiment. The avoiding slot 132 is designed considering the structural features of the second extension 23, and provides an accurate clamping position for the second extension 23. Meanwhile, the shape and size of the avoiding slot 132 are also accurately calculated to ensure the smoothness and stability of the clamping process. Correspondingly, the clamping block 233 is arranged at the upper end of the second extension 23. The shape and size of the clamping block 233 are matched with those of the avoiding slot 132, and the clamping block 233 can be tightly clamped in the avoiding slot 132. When the first fixed support 10 needs to be clamped below the second fixed support 20, the operator only needs to align the clamping block 233 of the second extension 23 with the avoiding slot 132 of the first extension 13, and then press it gently to realize the clamping.

[0057] The clamping structure not only enhances the connection stability between the first extension 13 and the second extension 23, but also improves the structural strength of the entire closed terminal support structure 2. The tight matching of the clamping block 233 and the avoiding slot 132 effectively prevents the first fixed support 10 and the second fixed support 20 from loosening or falling off in the working process of the connector 1, and meanwhile, the clamping block 233 can also be sealed at the upper end of the first extension 13 to prevent the first contact terminal 3 from being exposed to the air.

[0058] With reference to Figures 4 to 6In some embodiments of the present application, the second extension part 23 is provided with a fence part 234 on both sides, and the first extension part 13 is located between the fence parts 234. The fence part 234 is an integral part of the second extension part 23, extending along the two sides of the second extension part 23 to form a relatively closed space. The size and shape of this space can ensure that the first extension part 13 can be closely embedded therein. The presence of the fence part 234 not only provides stable support for the first extension part 13, but also effectively limits its movement in the horizontal direction, thereby enhancing the overall stability of the closed terminal holder structure 2. In actual application, when the first fixed support 10 is assembled with the second fixed support 20, the operator only needs to align the first extension part 13 with the fence parts 234 on both sides of the second extension part 23, and then gently push it in. The fence part 234 will tightly wrap the first extension part 13 to prevent it from loosening or shifting during the operation of the connector 1.

[0059] Referring to Figures 4 to 6 In some embodiments of the present application, the rear end of the second extension part 23 is provided with a third clamping groove 235, and the connector 1 comprises a third contact terminal 5 fixed in the third clamping groove 235. The third clamping groove 235 is designed at the rear end of the second extension part 23, and its shape and size match the outer shape of the third contact terminal 5 to ensure that the third contact terminal 5 can be closely and stably embedded therein. This design not only provides a reliable fixing point for the third contact terminal 5, but also ensures its correct position and good electrical contact in the connector 1. In actual application, when the third contact terminal 5 needs to be added in the connector 1, the operator only needs to align the third contact terminal 5 with the third clamping groove 235 at the rear end of the second extension part 23, and then gently push it in to achieve fixation. The close fit of the third clamping groove 235 ensures that the third contact terminal 5 will not loosen or shift during the operation of the connector 1, thereby ensuring the stability and reliability of the connector 1.

[0060] In some embodiments of the present application, the closed terminal holder structure 2 is made of insulating material. Insulating material is a material widely used in electrical engineering, which has the main feature of excellent insulating performance, i.e. it can prevent current from passing through, thereby preventing electrical short circuit and electric shock accidents. The use of insulating material in the closed terminal holder structure 2 can effectively isolate the electrical path between the connection terminals, avoiding electrical failure or safety accidents caused by accidental contact or short circuit. In actual application, as an important part of the connector 1, the closed terminal holder structure 2 often needs to withstand various electrical and environmental stresses. The closed terminal holder structure 2 made of insulating material not only provides stable mechanical support and fixing effect, but also ensures the safety and reliability of the connector 1 in electrical performance.

[0061] With reference to Figures 2 to 3 According to the second aspect embodiment of the utility model, the connector 1 comprises the closed terminal support structure 2 of any one of the first aspect embodiments. By adopting the closed terminal support structure 2 of any one of the above claims, the connector 1 can realize stable fixation and accurate alignment of the connecting terminal. Whether through the clamping structure of the first fixing support 10 and the second fixing support 20, or through the design elements such as the extension, the clamping groove, the abutting portion 232 and the enclosing portion 234, the firmness and stability of the connecting terminal in the connector 1 can be ensured. This not only improves the mechanical strength of the connector 1, but also ensures its reliability and durability in electrical connection. In addition, since the closed terminal support structure 2 is made of insulating material, the connector 1 also has excellent insulation performance. This feature enables the connector 1 to effectively isolate the electrical paths between different circuits in electrical connection, preventing safety accidents such as electrical short circuit and electric shock. At the same time, the insulating material also endows the connector 1 with properties such as aging resistance, corrosion resistance and high temperature resistance, further improving its ability to adapt to various harsh environments.

[0062] Therefore, it can be understood that the connector 1 according to the utility model embodiment has at least the following beneficial effects: the connector 1 wraps and embeds the connecting terminal in the first clamping groove 11 formed by the tongue plate portion 12, the connecting portion 14 and the first extension 13 of the closed terminal support structure 2 therein, thereby better preventing the situation of circuit short circuit caused by metal waste falling into during production, and further improving the reliability and safety of the connector 1.

[0063] The utility model embodiments are described in detail above in combination with the drawings, but the utility model is not limited to the above embodiments, and various changes can be made within the knowledge range possessed by ordinary skilled persons in the technical field without departing from the purpose of the utility model.
