Description

Inter-board connector for communication

Technical Field

The utility model relates to a communication engineering technical field specifically is a connector between boards for communication.

Background

Along with the continuous extension of intelligent communication, indoor wifi covers little basic station and the arrival of 5G era, the miniaturized demand of complete machine, and signal of telecommunication transmission system must adopt interplate connector in a large number in the rack. The board-to-board connector has the functions of blind insertion, board-to-board connection and multipoint connection, and is a great revolution of the use mode of the radio frequency connector. The existing inter-board connector is generally 3 or 2 pieces, each external member has no direct connection relation before assembly, and the external shape of the external member is single, so that the assembly gap is difficult to fill, and the stability of the assembled plate is influenced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a connector between board for communication to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a connector between boards for communication, includes screw rod and threaded sleeve, the threaded sleeve cup joints in the outside of screw rod, the inclined groove has been seted up at the middle part of screw rod, and the upper end integrated into one piece of screw rod has the cooperation end, the inside wall integrated into one piece of threaded sleeve has the annular flange of embedding inclined groove, and the upper end integrated into one piece of threaded sleeve has the joint end.

Compared with the prior art, the beneficial effects of the utility model are that: a connector between communication plates is characterized in that a worker inserts the connector into an assembly hole matched with the connector, firstly, a threaded sleeve of a tool such as a wrench is screwed in the assembly hole of a plate, then a screw is screwed on a box body or a cabinet body by rotating the screw through the tool such as a screwdriver, in the assembly process, when the threaded sleeve is screwed down, the lower edge of the clamping end extrudes the expansion sleeve to press the expansion sleeve into a gap without threads, when the screw rod is rotated, the inclined plane of the inclined groove continuously extrudes the annular flange, the pressure between the threads is increased to play a role in locking the threaded sleeve, the threaded sleeve is difficult to rotate on the premise of not loosening the screw rod, meanwhile, the reaction force of the annular flange extruding out of the inclined groove upwards can increase the pressure between the screw rod and the threads of the cabinet body, therefore, the effect of bidirectional locking is achieved, and when a worker dismantles the screw rod, the worker needs to press the screw rod forcibly to neutralize the reaction force while rotating the screw rod; all external members of this even connector all are in the joint state after production, do not have the external member and scatter the possibility of losing, all have certain deformation filling ability between each external member, can effectual filling plate pilot hole and the connector between the clearance, play the effect of stabilizing the plate.

Drawings

Fig. 1 is a front sectional view of the present invention.

In the figure: 1 screw rod, 2 threaded sleeve, 3 inflation cover, 4 inclined grooves, 5 annular flanges, 6 fixture blocks, 7 separation blades, 8 compensation grooves, 9 joint ends, 10 cooperation ends.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a connector between boards for communication, includes screw rod 1 and threaded sleeve 2, and threaded sleeve 2 cup joints in the outside of screw rod 1, and inclined groove 4 has been seted up at the middle part of screw rod 1, and the upper end integrated into one piece of screw rod 1 has mating end 10, and the inside wall integrated into one piece of threaded sleeve 2 has the annular flange 5 of embedding inclined groove 4, and the upper end integrated into one piece of threaded sleeve 2 has joint end 9.

Specifically, the screw 1 and the threaded sleeve 2 have threads both opened at the lower portion of the outer side wall.

Particularly, the upper portion welding of 2 lateral walls of threaded sleeve has fixture block 6, and threaded sleeve 2's outside has cup jointed expansion shell 3, and expansion shell 3's inner wall integrated into one piece has the separation blade 7 of joint between two fixture blocks 6.

Specifically, the length of the screw 1 is greater than the length of the threaded sleeve 2.

Particularly, the upper surface of cooperation end 10 is seted up the card hole that supplies the screwdriver joint, and the appearance of joint end 9 is the hexagon, and cooperation end 10 is the structure of cooperation screwdriver or small-size spanner, can play help staff's use tool rotate the effect of screw rod 1 can, joint end 9 is that the staff uses cup jointed tools such as spanner to rotate the structure of threaded sleeve 2, and its concrete appearance can be any shape, and it can through this structure rotation threaded sleeve to have supporting tool.

Specifically, compensation grooves 8 are uniformly formed in the upper end and the lower end of the side wall of the expansion sleeve 3, and gaps for metal deformation of the expansion sleeve 3 are reserved.

The working principle is as follows: when the utility model is used, a worker inserts the connector into an assembly hole matched with the connector, firstly uses a tool such as a wrench to screw the threaded sleeve 2 into the assembly hole of the plate, and then rotates the screw 1 through a tool such as a screwdriver to screw the screw to the box body or the cabinet body, in the assembly process, when the threaded sleeve 2 is screwed down, the lower edge of the clamping end 9 extrudes the expansion sleeve 3 to press the expansion sleeve into a gap without threads, when the screw 1 is rotated, the inclined surface of the inclined groove 4 continuously extrudes the annular flange 5, the pressure between the threads is increased to play a role in locking the threaded sleeve 2, the threaded sleeve 2 is difficult to rotate on the premise of not loosening the screw 1, meanwhile, the reaction force of the annular flange 5 extruding out of the inclined groove 4 upwards can increase the pressure between the screw 1 and the threads of the cabinet body, therefore, the effect of bidirectional locking is achieved, and when a worker dismantles the screw rod 1, the worker needs to forcibly press the screw rod 1 to neutralize the reaction force while rotating the screw rod 1; all external members of this even connector all are in the joint state after production, do not have the external member and scatter the possibility of losing, all have certain deformation filling ability between each external member, can effectual filling plate pilot hole and the connector between the clearance, play the effect of stabilizing the plate.
