Description

Technical Field

[0001] This utility model relates to the field of electronic components technology, and in particular to a limiting structure for a connector center pin. Background Technology

[0002] The center pin of a connector is a key component, typically composed of a ferrule and pins. It is mainly used inside the connector to transmit signals. In RF coaxial connectors, the center pin is the main part for signal transmission and is often referred to as the "center pin" or "inner conductor." RF coaxial connectors are widely used in wireless communication, satellite communication, radar systems, and other fields. The quality and performance of the center pin directly affect the signal transmission effect and system stability. When placing the center pin, a limiting structure is needed to limit its position.

[0003] The current connector center pin limiting structure can basically meet people's usage needs, but some problems still exist, as detailed below:

[0004] 1. The limiting structure of the connector center pin has difficulty guiding the center pin. When the center pin is in the limiting position, it may tilt due to its length, which affects the limiting of the center pin. Utility Model Content

[0005] The purpose of this invention is to provide a limiting structure for the center pin of a connector, so as to solve the defect that the existing limiting structure for the center pin of a connector is difficult to guide the center pin.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a limiting structure for a connector center pin, including a base;

[0007] The base has a movable groove inside, a movable block inside the movable groove, and a movable plate installed on the top of the movable block.

[0008] The top of the movable plate is equipped with an installation block, the top of the installation block is equipped with a fixing block, the top of the fixing block is equipped with a center pin body, and the top of the fixing block is equipped with a guide structure.

[0009] The guide structure includes a guide rod mounted on the top of the fixed block, a guide ring mounted on the outer side of the guide rod, a rubber pad mounted inside the guide ring, and a fixing screw mounted on the outer side of the guide ring.

[0010] In use, the center pin body can first be inserted into the fixed block for fixed positioning. The moving block at the bottom of the moving plate can slide along the moving groove. The sliding of the moving block can adjust the position of the top fixed block and the center pin body that is limited. When it is necessary to fix the moving plate, the mounting plate and the mounting screw form a threaded connection. Tighten the mounting screw by turning the screw block to fix the movement of the mounting plate.

[0011] Furthermore, the bottom end of the moving groove is provided with a sliding groove, and the bottom end of the moving block is provided with a slider. The moving groove and the moving block constitute a sliding structure, and the moving block can slide along the moving groove.

[0012] Furthermore, positioning structures are installed at both ends of the mounting block. The positioning structures include mounting plates installed at both ends of the mounting block, a screwing block at the top of the mounting plate, and a mounting screw at the bottom of the screwing block. The moving block can be fixed by tightening the mounting screw.

[0013] Furthermore, the mounting screws and the mounting plate form a threaded connection, and the mounting screws are symmetrically distributed about the central axis of the mounting block. Tightening the mounting block can adjust the height of the mounting screws.

[0014] Furthermore, clamping structures are installed on both sides of the fixing block. Each clamping structure includes a connecting plate installed at the top of the mounting block, a threaded rod passing through the middle of the connecting plate, a rotating block installed on one side of the threaded rod, and a limiting block installed on the other side of the threaded rod. The limiting block can fix the center pin body.

[0015] Furthermore, the outer side wall of the threaded rod is uniformly provided with external threads, and the inner side wall of the connecting plate is uniformly provided with internal threads that cooperate with the external threads. The threaded rod and the connecting plate are threadedly connected, and the rotation of the threaded rod can adjust the movement of the threaded rod.

[0016] Furthermore, the fixing screws and the guide ring form a threaded connection, and the fixing screws are arranged in a ring. Tightening the fixing screws can fix the guide ring.

[0017] The municipal engineering highway crack repair device with a smoothing mechanism provided by this utility model has the following advantages: the threaded rod can rotate to drive the limiting block to clamp the internal center needle and limit the center needle. At the same time, the height of the guide ring can be adjusted. When the center needle is limited, it passes through the guide rod. The guide ring can prevent the center needle from tilting when it is limited.

[0018] By installing a guide rod at the top of the fixed block, the guide ring and the guide rod form a sliding structure. The guide ring can slide along the guide rod, and the height of the guide ring can be adjusted to adapt to different situations. When it is necessary to fix the guide ring, tighten the fixing screw. Due to the pressure of the fixing screw, the guide ring can be fixed. The rubber pad inside the guide ring is made of elastic rubber material. The elasticity of the rubber pad can stably clamp the center pin body. The guide ring can guide the center pin body and prevent the center pin body from shifting during use. This achieves the purpose of the connector center pin limiting structure to facilitate the guidance of the center pin.

[0019] A connecting plate is installed at the top of the mounting block. The connecting plate and the threaded rod form a threaded connection. Tightening the rotating block drives the threaded rod to rotate. The rotation of the threaded rod drives the limiting block to move. The movement of the limiting block presses into the fixed block, squeezing and limiting the center pin body that is stuck inside the fixed block. The limiting block can be made of rubber material, which has strong friction and can limit and fix the center pin body. This achieves the purpose of the limiting structure of the connector center pin, which facilitates the stable limiting of the center pin body. Attached Figure Description
