Description

Digital signal extender

Technical Field

The utility model relates to a signal switching device, more specifically say, it relates to a digital signal extender.

Background

At present, with the great popularization of networks, the area of network cables is wider and wider, and developed networks are convenient for people to live and extend towards a longer distance. The effective communication distance of the current standard ethernet is 100 meters, and the data signal is weakened when the network cable exceeds the effective communication distance. Based on this, at present, the network cable is usually connected by a router, a switch or a HUB, so as to ensure that the data signal transmitted by the network cable is less affected, and achieve the purpose of network extension.

The digital signal extender is an extension device applied to a network, and the application of the digital signal extender is more and more extensive. The digital signal extender at least comprises two signal interfaces, namely an input signal interface and an output signal interface. The digital signal extender can be connected to the network by inserting the connecting plug into the signal interface. Since the digital signal extender essentially acts as a signal relay, it is necessary for the network to normally transmit information to ensure the reliability of its connection to other network devices.

The signal interface of the existing digital signal extender is simple, and only a signal plug is inserted into the signal interface, so that the signal plug cannot be effectively fixed, the signal plug is easy to loose or the contact is poor, and the stable operation of a network is influenced.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a digital signal extender, its reliability of connection is guaranteed in the signal plug that can effectively lock.

In order to achieve the above purpose, the utility model provides a following technical scheme:

a digital signal extender comprises a shell and a signal interface, wherein the signal interface is used for inserting a signal plug, the signal interface comprises an interface sleeve and a contact core arranged in the interface sleeve, the signal plug comprises a plug sleeve, a contact core arranged in the plug sleeve and a plug shell covering the plug sleeve, a pair of clamping pieces are symmetrically arranged on the periphery of the interface sleeve, the clamping pieces are in a circular arc shape fitted with the shape of the plug shell, the space between each clamping piece and the interface sleeve is used for allowing the plug sleeve and the plug shell to enter, one end of each clamping piece is fixedly connected with the shell, the other end of each clamping piece is a free end, the thickness of each clamping piece is gradually increased along the direction far away from the shell, a locking nut is further sleeved on the outer side of each clamping piece, an external thread is arranged on the inner wall of each locking nut, and an internal thread is arranged on the outer wall of each clamping piece, the locking nut is in threaded connection with the clamping piece.

As a preferable scheme: the inner wall of the clamping piece is provided with a convex block, and the part of the plug shell corresponding to the convex block is provided with an annular clamping groove.

As a preferable scheme: the cross-sectional shapes of the clamping groove and the lug are both trapezoidal.

As a preferable scheme: the surface of the locking nut is provided with anti-skid grains.

Compared with the prior art, the utility model has the advantages that: after the digital signal extender is inserted, the locking nut is screwed to enable the digital signal extender to move forward, the clamping piece is extruded by the locking nut at the moment, and the clamping piece gradually clamps the plug shell, so that the signal plug is locked and is not easy to loosen, and the connection reliability is ensured; in addition, the inner wall of the clamping piece is provided with a convex block, and the part of the plug shell corresponding to the convex block is provided with an annular clamping groove. After the signal plug is inserted in place, the convex block just enters the clamping groove, and the locking nut is screwed down to enable the clamping piece to compress the plug shell, so that the convex block is firmly clamped in the clamping groove to form more stable and reliable connection.

Detailed Description

Referring to fig. 1 and 2, the digital signal extender includes a housing 1 and a signal interface, the signal interface is used for plugging a signal plug 3, the signal interface includes an interface sleeve 2 and a contact core arranged in the interface sleeve 2, and the signal plug 3 includes a plug sleeve 301, a contact core arranged in the plug sleeve 301, and a plug shell 302 covering the plug sleeve 301. The plug ferrule 301 is adapted to be sleeved outside the interface ferrule 2.

A pair of clamping pieces 5 are symmetrically arranged on the periphery of the interface sleeve 2, the shape of each clamping piece 5 is an arc shape fitting the shape of the plug shell 302, and a space between each clamping piece 5 and the interface sleeve 2 is used for the plug sleeve 301 and the plug shell 302 to enter. The one end of pressing from both sides tight piece 5 is connected fixedly with casing 1, and the other end that presss from both sides tight piece 5 is the free end, along the direction of keeping away from casing 1, and the thickness that presss from both sides tight piece 5 grows gradually, still overlaps in the outside that two press from both sides tight piece 5 and has lock nut 4, and lock nut 4's inner wall is provided with external screw thread 6, is provided with internal thread 7 on pressing from both sides the outer wall of tight piece 5, lock nut 4's external screw thread 6 and the internal thread 7 adaptation that presss from both sides tight piece 5, lock nut 4 and the tight.

Before inserting signal plug 3 into signal interface, need to twist lock nut 4 and make it retreat (moving towards the direction that is close to casing 1 promptly), press from both sides tight piece 5 and loosen this moment, the user can easily insert signal plug 3 into signal interface, accomplish the grafting back, twist lock nut 4 and make it advance (moving towards the direction of keeping away from casing 1 promptly), press from both sides tight piece 5 and receive lock nut 4's extrusion this moment, press from both sides tight piece 5 and press from both sides tight plug shell 302 gradually, thereby lock signal plug 3, make it difficult pine take off, guarantee the reliability of connecting.
