Description

Technical Field

[0001] This utility model relates to the field of connectors, and more particularly to a connector with vibration resistance. Background Technology

[0002] Currently, in the intelligent upgrading of engineering electrical equipment, it is usually necessary to connect the equipment to the network through fiber optic connectors. The current implementation plan is to install ceramic pins on the male and female ends of the heavy-duty connector, and achieve optical path conduction by interlocking the end faces of the two ceramic pins.

[0003] However, many electrical devices generate significant vibrations during operation. To facilitate insertion and removal, connectors typically use a clearance fit between the male and female ends, resulting in a gap between them after mating. When the vibrations of the device are transmitted through the connector to the two precisely mated ceramic pins, they cause high-frequency micro-collisions and friction. When the ceramic pins are under such conditions for a long time, the hard but brittle ceramic pins are prone to wear or even breakage at the contact end, ultimately leading to attenuation and interruption of optical signal transmission, affecting the stability and reliability of the network connection. Utility Model Content

[0035] The docking post 43 is placed in the second mounting hole 411, and the second elastic element 44 is fitted onto the outside of the second limiting post 432 of the docking post 43.

Then, the top of the second connecting seat 42 is inserted into the bottom of the second docking member 41, so that the second elastic element 44 is fitted onto the outside of the second limiting post 432 of the second mounting cavity 421. The second elastic element 44 pushes the second contact surface 431 of the docking post 43 to fit against the second positioning surface 412.

The contact pin 111 of the male connector 1 slides into the second mating hole of the female connector 2, and the spring sleeve 112 of the female connector 2 clamps the contact pin 111 of the male connector 1; the contact pin 111 of the female connector 2 slides into the second mating hole of the male connector 1, and the spring sleeve 112 of the male connector 1 clamps the contact pin 111 of the female connector 2, thereby realizing the conduction of current in the electrical equipment. The top of the second docking piece 41 is inserted into the slot 314, so that the axis of the first through hole coincides with the axis of the second through hole, allowing the pin 33 to slide precisely into the first docking hole 434. The third contact surface 333 fits against the third positioning surface 433. The crown spring 45 clamps the pin 33, and under the joint constraint of the crown spring 45 and the third contact surface 333, it ensures that the axis of the pin 33 and the axis of the docking post 43 always coincide and are parallel, thus realizing network data transmission. The pin 33 pushes the docking post 43 to compress the second elastic element 44, and under the reaction force of the second elastic element 44, the pin 33 compresses the first elastic element 34. The first elastic element 34 and the second elastic element 44 together support the pin 33 and the docking post 43 in a suspended state, thereby buffering the vibration of external equipment and reducing the collision and friction at the contact part of the pin 33 and the docking post 43.

By utilizing a conical structure design where the first contact surface, the first positioning surface, the second contact surface, and the second positioning surface are all conical, the first contact surface of the pin is fitted with the first positioning surface to position the pin's axis center at the axis center of the first through hole; simultaneously, the second contact surface of the mating post is fitted with the second positioning surface to position the mating post's axis center at the axis center of the second through hole, thereby achieving precise alignment between the pin and the mating post. When the female connector is inserted into the male connector, the first and second connectors align, the pin slides into the first mating hole and pushes the mating post to compress the second elastic element; under the reaction force of the second elastic element, the pin compresses the first elastic element, so that the first and second elastic elements together support the pin and the mating post in a suspended state. By setting the first gap and the second gap, a certain amount of lateral movement space is given to the pin and the docking post; when the vibration of the external electrical equipment is transmitted to the first and second pins, the first elastic element and the second elastic element can effectively buffer the transmission of vibration to the pin and the docking post, reduce the collision and friction at the contact point between them, thereby reducing the damage of vibration to the structure and extending the service life.
