Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector equipment, and in particular to a magnetic fiber optic connector. Background Technology
[0002] Fiber optic connectors, by configuring different types of optical interfaces, can meet various connection and communication needs. When using the MT interface, high-density optical signal transmission can be achieved, which helps save space, improve system integration, and meet the real-time requirements of system control signal transmission. Conventional fiber optic connectors require manual or mechanical locking or unlocking during installation or removal to achieve plug and socket insertion / removal. However, mechanically quick-plug fiber optic connectors are typically bulky, expensive, difficult to blind-mating, and cannot be quickly plugged in or removed. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a magnetic fiber optic connector.
[0004] This utility model is achieved through the following technical solution.
[0005] This utility model provides a magnetic fiber optic connector, including a plug and a socket. The plug includes a plug housing, a plug base, and an MT fiber optic connector male. The rear end of the plug housing is connected to the front end of the plug base. The MT fiber optic connector male is mounted on the plug base, and its contact end passes through the plug housing and is located at the front end of the plug housing. The socket includes a socket housing, a socket base, and an MT fiber optic connector female. The rear end of the socket housing is connected to the front end of the socket base. The MT fiber optic connector female is mounted on the socket base, and its contact end passes through the socket housing and is located at the front end of the socket housing. The front end of the plug housing has a groove, and the front end of the socket housing has a boss. The groove and the boss are engaged and fitted together.
[0006] Preferably, the front end of the plug housing is provided with an S-pole magnet A and an N-pole magnet A, which are respectively distributed at opposite corners of the front end of the plug housing. The front end of the socket housing is also provided with an S-pole magnet B and an N-pole magnet B, which are respectively distributed at opposite corners of the front end of the socket housing. The S-pole magnet A and the N-pole magnet B are arranged opposite each other.
[0007] Preferably, the plug housing and the plug base are both fitted with a two-part tailpiece, and a wire harness protective sleeve is installed at the rear end of the two-part tailpiece, through which the optical cable of the male MT fiber optic connector passes.
[0008] Preferably, the wire harness protective sleeve is fitted with a wire clip.
[0009] Preferably, a sealing gasket is provided on the plug housing.
[0010] Preferably, the plug housing is provided with a first limiting hole, and the plug base is provided with a first limiting protrusion, and the first limiting hole and the first limiting protrusion are engaged and adapted to each other.
[0011] Preferably, the socket housing is provided with a second limiting hole, and the socket base is provided with a second limiting protrusion, and the second limiting hole and the second limiting protrusion are engaged and adapted to each other.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. Make contact between the contact ends of the plug shell and the contact ends of the socket shell, so that the protrusion engages with the groove. At the same time, the corresponding S-pole magnet A and N-pole magnet B attract each other, and the N-pole magnet A and S-pole magnet B attract each other, so that the male and female MT fiber optic connectors can quickly and accurately align, achieving optical path connection. When it is necessary to disconnect the optical path, apply a force to the plug and socket that is opposite to the alignment direction and greater than the magnetic force, so that the contact ends of the plug and socket can be separated along the axial direction, thus disconnecting the optical path.
[0014] 2. By matching the N and S polarities of S-pole magnet A, N-pole magnet B, N-pole magnet A and S-pole magnet B, when the socket is placed in reverse, the polarities of the magnets on the plug and socket repel each other, preventing the plug and socket from mating. This achieves the connector's anti-misinsertion function and provides blind-insertion capability. Attached Figure Description

The S-pole magnet 14 and N-pole magnet 18 are positioned opposite each other, as are the N-pole magnet 13 and S-pole magnet 19. When the plug and... When the sockets are connected, the S-pole magnet A14 and the N-pole magnet B18 attract each other, and the N-pole magnet A13 and the S-pole magnet B19 attract each other, enabling the plug 1 and socket 2 to connect quickly and accurately. When the plug 1 or socket 2 is reversed, the polarities will repel each other during the connection process, preventing the plug 1 and socket 2 from connecting. This helps to prevent the plug 1 or socket 2 from being connected in reverse, thus providing the plug 1 and socket 2 with anti-misinsertion function and blind insertion function.
[0036] The working principle of this embodiment is as follows: The contact ends of the plug housing 3 and the socket housing 10 are brought into contact with each other, so that the boss 21 is engaged in the groove 20.
