Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of connectors, in particular to an anti-loosening connector. Background Art
[0002] Connectors are a commonly used electronic component, mainly used to connect two lines or devices and ensure a stable connection between them. So far, connectors have developed into a series of specialized products with a complete range of products, rich varieties and specifications, diverse structural types, subdivided professional directions, obvious industry characteristics, and standardized standard systems. The existing connector structure design is unreasonable. During long-term use, the connector may become loose or fall off, affecting the normal operation of the equipment, and thus the connector has the defects of unreliable performance and unreliable connection. Utility Model Content
[0003] In view of this, an object of the utility model is to provide an anti-loosening connector with simple structure, reliable performance and reliable connection.
[0004] In order to achieve the above purpose, the utility model adopts such an anti-loosening connector, including a plastic shell, a pin arranged in the plastic shell, one end of the pin has a first plug-in portion extending outside the plastic shell and plugged with a circuit board, the other end of the pin has a second plug-in portion extending inside the plastic shell, the cross-sectional shape of the pin is square, and plug-in boards are provided on both sides of the outer wall of the plastic shell corresponding to the first plug-in portion, the bottom of the plug-in board extends outward to form a protrusion, one side of the protrusion is provided with a guide inclined surface, and the other side is provided with a limiting inclined surface.
[0005] The beneficial effect of the above structure is that one end of the pin is plugged into the circuit board, and the other end extends into the plastic shell. Such a design structure makes the connector not easy to shake or misalign, and the other end of the pin extends into the plastic shell, which can protect the connection point between the pin and the circuit board and avoid damage to the connection point caused by external force. The cross-sectional shape of the pin is square, which can increase the contact surface of the pin and improve the conduction reliability. The protrusion plays a role of limiting when the connector is inserted into the circuit board, preventing the connector from loosening or falling off the circuit board, so that the connector has the advantages of simple structure, reliable performance and reliable connection.
[0006] The utility model is further configured that the outer wall of the plastic shell is also provided with a card plate corresponding to the second plug-in part, and the top of the card plate extends outward to form a card hook. The design of the card hook can be matched with the corresponding structure on other connectors to increase the stability of the connector and prevent it from loosening from the circuit board.
[0007] The utility model is further configured that a guide groove is further arranged in the plastic shell corresponding to the second plug-in portion. The guide groove can play a guiding role, and can make the plug-in smoother. BRIEF DESCRIPTION OF THE DRAWINGS
