Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and particularly relates to a connector with a reverse buckle terminal. Background Art

[0002] A connector is an electrical connector, also called a connector or a plug, and is also called a connector or a socket in China. Generally, it refers to an electrical connector, that is, a device that connects two active devices, transmits current or signals. The male end and the female end can transmit information or current after contact, and it is also called a connector.

[0003] For a conventional connector with a reverse buckle terminal, the reverse buckle terminal adopts a structure integrally injection-molded with the housing. Although the cost is very low, the locking structure provided by the toughness of this material follows. With the number of uses, the structure is repeatedly stressed and bent, so that the structural stability is likely to fail or even break.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a connector with a reverse buckle terminal is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a connector with a reverse buckle terminal to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A connector with a reverse buckle terminal includes a wiring end and a reverse buckle structure. One end of the wiring end is connected with a sheath assembly, and a contact pin is installed at one end of the sheath assembly away from the wiring end. The reverse buckle structure is installed on the left and right sides of the sheath assembly. A sitting component is arranged at one end of the contact pin away from the sheath assembly, and a contact terminal is installed inside one end of the sitting component. A fixing seat is connected to one side of the sitting component away from the contact pin. The reverse buckle structure includes a pressing plate, a reverse buckle block, a support shaft, a movable shaft and a spring telescopic rod. One end of the pressing plate is connected with the reverse buckle block, one side of the middle part of the pressing plate is connected with the support shaft, and a movable shaft is arranged at one end of the support shaft away from the reverse buckle block. And a spring telescopic rod is connected to one side of the movable shaft away from the pressing plate.

[0007] Further, the sheath assembly includes a plug housing, a sealing ring and a guard plate. A sealing ring is embedded at one end of the plug housing away from the wiring end, and guard plates are horizontally connected to the upper and lower sides of one end of the plug housing close to the sitting component.

[0008] Further, the sheath assembly further includes a buffer block and a connecting post. Buffer blocks are connected to the left and right sides of the plug housing, and connecting posts are horizontally inserted into one side of the buffer blocks close to the sitting component.

[0009] Furthermore, the plug housing and the buffer block are an integrated structure, and the connecting piles are symmetrically arranged at the upper and lower ends of the buffer block.

[0010] Furthermore, the undercut structure is horizontally arranged in the middle of the buffer block, and the undercut structure is arranged in the middle of the buffer block in a sunken structure.

[0011] Furthermore, the end seat assembly includes a socket shell, a buckle hole, and a sealing groove. The left and right sides of the socket shell are provided with buckle holes, and the surface of the socket shell close to the contact pin is provided with a sealing groove.

[0012] Furthermore, the end seat assembly also includes a protective block and a connecting hole. The left and right sides of the socket shell are connected to the protective blocks, and the upper and lower ends of the protective blocks are horizontally provided with connecting holes.

[0013] Furthermore, the internal structure of the sealing groove matches the surface structure of the sealing ring, and the internal structure of the connecting hole matches the surface structure of the connecting pile.

[0014] The utility model provides a connector with undercut terminals, which has the following beneficial effects:

[0015] 1. The utility model has an undercut structure installed on the left and right sides of the sheath assembly, which cooperates with the undercut holes opened on the left and right sides of the socket shell. When the contact pin and the contact terminal are structurally inserted in the horizontal direction, with the assistance of the structural extension of the spring telescopic rod and the movable structure of the supporting shaft, the undercut block at one end of the pressing plate will be directly clamped in the inside of the undercut hole. At the same time, under the structural support of the spring telescopic rod, one end of the pressing plate connected with it by the movable shaft is supported, so that the undercut block at the other end of the pressing plate is pressed tightly against the inside of the undercut hole by the lever structure to form a locking structure. At the same time, the connecting pile is horizontally inserted into the inside of the connecting hole, and the friction force of the insertion structure is used to assist the stability and firmness of the connection between the structures. By using the above structure, the undercut terminal of the integrated structure can be avoided to the greatest extent. After long-term reciprocating use of the bending structure, the locking limit function is lost due to material structure fatigue, so that the connection locking of the overall structure cannot play an effective role. The use of this structure can effectively avoid such a situation while also ensuring the firmness of the structural locking and the structural flexibility to the greatest extent.

[0016] 2. The utility model, through the use of buffer blocks and protective blocks, can, on the one hand, provide structural reinforcement for the plug housing and the socket housing, and can reduce as much as possible the structural damage to the contact pins and the contact terminals caused by external forces. On the other hand, it can also provide a certain degree of structural shielding and protection for the undercut structure after the sheath assembly and the end seat assembly are connected to each other, to avoid structural damage caused by bumps. At the same time, the protective plates horizontally arranged on the upper and lower sides of the plug housing can provide structural support for the connection between the sheath assembly and the end seat assembly after the connection to a certain extent, and reduce as much as possible the structural bending caused by external forces, which may cause greater damage to the contact pins and contact terminals after the connection. In addition, the sealing ring arranged around the outside of the contact pin, in cooperation with the sealing ring opened around the contact terminal, can avoid to the greatest extent the situation of short circuit and burning caused by moisture leakage after the connection is connected, thereby further ensuring the safety of use.

[0023] The sheath assembly 2 includes a plug housing 201, a sealing ring 202, and a guard plate 203. The sealing ring 202 is embedded at one end of the plug housing 201 away from the terminal 1, and the guard plate 203 is horizontally connected to the upper and lower sides of the end of the plug housing 201 close to the end sitting assembly 5. The sheath assembly 2 also includes a buffer block 204 and a connecting pile 205.
