Description

Technical Field

[0001] This utility model relates to the field of electronic component technology, and in particular to a break-resistant terminal connector center pin. Background Technology

[0002] The connector center pin is a key component of a connector, typically consisting of a ferrule and a pin. It is mainly used inside the connector to ensure stable signal transmission. The design and material selection of the center pin have a significant impact on its performance. As the core component of the connector, the center pin is mainly responsible for signal transmission. It is usually made of conductive materials, such as copper or alloys, which have good conductivity and stability. The design of the center pin requires precise control of its diameter and length to ensure good contact with the pin, thereby reducing signal loss and interference.

[0003] To address this, Chinese patent application CN207530248U discloses a coaxial connector center pin, comprising an insulating layer, a connecting hole, and a connector head; the insulating layer is located outside the connecting hole; the connector head is connected to the rear end of the connecting hole; the connector head has a first step, a second step, and a third step; the length of the first step is greater than the length of the second step. This invention simply changes the step length of the connector center pin, without affecting the appearance and with simple operation, thereby achieving the purpose of increasing the characteristic impedance.

[0004] 1. The above-mentioned coaxial connector center pin is proposed to improve the characteristic impedance by simply changing the step length of the connector center pin without affecting the appearance and with simple operation. However, the center pin body may be damaged after long-term use and needs to be replaced. Summary of the Invention

[0005] The purpose of this invention is to provide a break-resistant center pin for a terminal connector, thereby solving the problem that existing center pins for terminal connectors are difficult to disassemble.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a breakage-resistant terminal connector center pin, including a base plate;

[0007] A connecting plate is installed at the top of the base plate, a base is installed at the top of the connecting plate, and a disassembly structure is installed at the top of the base.

[0008] The disassembly and assembly structure includes a fixing plate installed on the top of the base, a rotating shaft installed on the inner side of the fixing plate, and a buckle installed on the top of the rotating shaft;

[0009] A mounting block is installed at the top of the base, a baffle is installed at the top of the mounting block, a telescopic rod is installed at the top of the baffle, a telescopic structure is installed at the top of the telescopic rod, and a center pin body is installed at the top of the telescopic structure.

[0010] In use, the bottom of the baffle can first be inserted into the slot inside the mounting block. After the baffle is inserted into the mounting block, the center pin body can be installed on the top of the mounting block. The rotating shaft inside the fixing plate can rotate, which will drive the buckle to rotate. The buckle will lock the baffle and fix it to the top of the mounting block to prevent the baffle from falling off. When the center pin body needs to be replaced, rotate the buckle so that it is no longer locking the baffle, and then the center pin body can be replaced.

[0011] Furthermore, the mounting block has a slot inside, and the bottom of the baffle has a locking block. The mounting block and the baffle form a locking structure, which facilitates disassembly.

[0012] Furthermore, a reinforcing structure is installed inside the central needle body. The reinforcing structure includes a reinforcing layer disposed inside the central needle body, and a first reinforcing rib is installed inside the reinforcing layer. The first reinforcing rib and the second reinforcing rib can enhance the structural strength of the central needle body.

[0013] Furthermore, a second reinforcing rib is installed inside the reinforcing layer. The second reinforcing rib is arranged at equal intervals inside the reinforcing layer, while the first and second reinforcing ribs are both distributed in a ring.

[0014] Furthermore, the telescopic structure includes a telescopic block installed at the top of the telescopic rod, a fixing screw is installed on one side of the telescopic block, and a screwing block is installed on the other side of the fixing screw, allowing the center pin body to slide inside the telescopic block.

[0015] Furthermore, the outer side wall of the fixing screw is uniformly provided with external threads, and the inner side wall of the telescopic block is uniformly provided with internal threads that cooperate with the external threads. The fixing screw and the telescopic block are connected by threads, and tightening the fixing screw can fix the center pin body.

[0016] Furthermore, the inner diameter of the telescopic block is larger than the outer diameter of the central needle body, and the telescopic block and the central needle body form a sliding structure, allowing the central needle body to slide along the telescopic block.

[0017] The breakage-resistant terminal connector center pin provided by this utility model has the following advantages: During use, both the center pin body and the telescopic rod at the bottom can be inserted into the mounting block for installation. Simultaneously, the center pin body is fixed to the mounting block by a snap-lock mechanism that holds the bottom baffle. When replacement is needed, simply rotate the snap-lock mechanism to release it from the baffle, allowing the center pin body to be replaced.

[0018] By installing a baffle at the top of the mounting block, the locking block at the bottom of the baffle can be inserted into the locking groove inside the mounting block. After the baffle is inserted into the mounting block, the center pin body can be installed at the top of the mounting block. The rotating shaft inside the fixing plate can rotate, and the rotation of the rotating shaft will drive the buckle to rotate. The rotation of the buckle will lock the baffle, fixing the baffle at the top of the mounting block and preventing the baffle from falling off. When the center pin body needs to be replaced, rotate the buckle so that the buckle is no longer locking the baffle, and the center pin body can be replaced. This achieves the purpose of making it easy to disassemble the center pin body of the terminal connector center pin.

[0019] By installing a telescopic block at the top of the telescopic rod, the telescopic block and the center pin body form a sliding structure. The center pin body can slide along the telescopic block and the telescopic rod. The extension and retraction of the center pin body can adjust the height of the center pin body, allowing the center pin body to adapt to different situations. When it is necessary to fix the center pin body, turning the screw block can tighten the fixing screw to fix the center pin body. This achieves the purpose of making it easy to adjust the height of the center pin body of the terminal connector center pin. Attached Figure Description
