Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 to 6, a specific embodiment 1 of the connector assembly of the present invention includes a plug 2 and a socket 1, the plug 2 includes a plug housing assembly, the plug housing assembly includes a plug housing 21 having a front end as a plugging end and a rear end as a terminal, the socket 1 includes a socket housing, and ferrule structures adapted to each other are disposed in the plug housing and the socket housing, and the ferrule structures may be electrical ferrules, optical ferrules, or optical and electrical mixed ferrules. The plug housing 21 is provided with a locking member which is slidably assembled along the front-rear direction, the socket housing is provided with a slot 11, a slot wall on one side of the slot 11 close to the plugging position forms an anti-dropping stop surface, the locking member is provided with a locking claw 23 which is cantilevered forwards, the locking claw 23 is provided with a locking block 24 which is used for being buckled in the slot 11 on the socket housing, the front end of the plug housing 21 is provided with a locking connecting part 25, and the locking connecting part 25 is used for being matched with the locking block 24 in the slot 11 of the socket housing in a backward stop manner, so that the plug housing 21 and the socket housing are prevented from moving.
After the plug and the socket are inserted in place, the locking piece 24 on the locking claw 23 is buckled in the slot 11 of the plug housing 21, and the locking connecting part 25 on the plug housing 21 is in stop fit with the front side surface of the locking piece 24 in the slot 11, so that when the plug is subjected to a pulling force, the locking piece 24 in the slot 11 stops the locking connecting part 25 backwards to prevent the plug from moving backwards. At this time, because the locking member is in sliding fit with the plug housing 21, the locking member only receives a small sliding friction force, the locking block 24 is mainly used for bearing the pulling force between the plug and the socket, namely the pulling force is converted into the extrusion force received by the locking block 24, the anti-extrusion strength of the locking block 24 is high, and reliable locking force is ensured.
In this embodiment, a locking structure is provided between the locking connection portion 25 and the locking block 24, so that the locking block 24 is forced to be radially close to the inside of the slot 11 of the socket when the locking connection portion 25 applies a backward pressing force to the locking block 24. Therefore, the backward jacking force of the locking connecting part 25 on the locking block 24 is converted into the force of radial movement of the locking block 24 through the locking structure, so that the locking block 24 is pressed in the clamping groove 11, the locking block 24 is prevented from being separated from the clamping groove 11, and the anti-falling capacity of the connector is improved.
In the present embodiment, as shown in fig. 4, the locking structure includes an inclined locking surface 243 disposed on one of the stopper and the locking piece 24, and the front end of the inclined locking surface 243 is inclined toward the inside of the plug housing 21, specifically, the inclined locking surface 243 is disposed at the upper side position of the front end of the locking piece 24, and the inclined surface structure is convenient to process.
In this embodiment, the locking claw 23 is an elastic locking claw 23 capable of elastically deforming along the radial direction of the plug housing 21, an unlocking structure for smoothly abutting and matching with the groove wall of the slot 11 of the socket housing is arranged on the rear side of the locking piece 24, so that the locking piece 24 is forced to move in the direction away from the slot 11 when the locking piece moves backwards relative to the plug housing 21, and thus when the locking piece moves backwards, the locking piece 24 drives the elastic claw to move in the direction away from the slot 11 under the action of the unlocking structure, so that the locking piece 24 is disengaged from the slot 11, and thus, the unlocking of the plug and the socket can be completed. Adopt this kind of unlocking structure to realize the unblock, need not to set up other unlocking parts in addition, simple structure.
Specifically, the unlocking structure includes an inclined unlocking surface 242 provided on the lock block 24, the rear end of the inclined unlocking surface 242 is inclined toward the outer side of the plug housing 21, and the inclined surface structure is adopted to make the lock block 24 simple in structure and convenient to process. Meanwhile, a guide slope 241 is provided at a lower side of a front end of the locking piece 24 to facilitate the insertion of the socket housing between the locking claw 23 and the plug housing 21.
In this embodiment, the locking member is a locking cap 22 slidably fitted on the plug housing 21 in the front-rear direction, and locking claws 23 are provided on opposite sides of the locking cap 22. Specifically, the cross section of the locking cap 22 is a U-shaped structure, the locking claws 23 are arranged on opposite sides of the locking cap 22, and four locking claws 23 are arranged side by side on each side, so that the locking capacity is improved. The plug housing 21 is provided with a U-shaped notch for guiding the locking cap 22 to move in the front-rear direction, and a groove wall of the front side of the U-shaped notch forms a locking connection portion 25. To enable the locking cap 22 to slide in the U-shaped notch in the fore-aft direction, the dimension of the U-shaped slot in the fore-aft direction should be greater than the dimension of the locking cap 22.
The plug and the socket are rectangular connectors, the front end of the plug housing 21 is provided with three steps, namely a first step 211, a second step 212 and a third step 213, wherein the radial step surface of the first step 211 is used for stopping and positioning the socket housing backwards (the rear side of the plug), the second step 212 is mainly used for avoiding the locking claw 23 so as to enable the locking claw to deform radially, and the third step 213 is used for installing the locking cap 22 so as to enable the locking cap 22 to slide relatively on the third step 213. The second step 212 and the third step 213 are both U-shaped, and the third step 213 forms the U-shaped notch.
The plug shell 21 is provided with a guide groove extending along the front-back direction, the locking cap 22 is provided with a guide protrusion clamped in the guide groove and movably matched with the guide groove in a guide manner, the sliding fit between the locking cap 22 and the socket shell is realized through the matching of the guide protrusion and the guide groove, and meanwhile, the locking cap 22 is prevented from being separated from the plug shell 21.
The process of butt-jointing and inserting the plug and the socket of the present invention is shown in fig. 5, the locking cap 22 is held by hand to insert the plug into the socket, the socket housing passes through the locking connection portion 25 to enter between the locking block 24 and the plug housing 21, and the locking block 24 moves upward under the pressing force of the socket housing. And continuously applying the pushing force, enabling the socket and the plug to be continuously close to each other, stopping the front end face of the socket shell on the step face of the first stopping step when the socket is inserted in place, enabling the locking connecting part 25 to just cross the clamping groove 11 at the moment, and buckling the locking block 24 in the clamping groove 11 to complete the locking connection of the plug and the socket.
When a pulling force is applied between the plug and the socket, the pulling force acts on the locking block 24 through the locking connecting portion 25 on the socket housing, and the locking block 24 is firmly locked in the locking slot 11 by the inclined locking surface 243, and neither the locking cap 22 nor the locking claws 23 on the locking cap 22 is subjected to the pulling force. When unlocking, the locking cap 22 is held by hand to exert a pulling force backwards, the locking block 24 is disengaged from the clamping groove 11 under the action of the inclined unlocking surface, at the moment, the plug and the socket are unlocked, the locking cap 22 is continuously operated to move backwards, the rear end of the unlocking cap is in stop fit with the third step 213, and therefore the plug shell 21 is driven to move backwards, and the plug and the socket are completely disengaged.
