Description

A kind of telephone wire crystal head

Technical field

The utility model is related to arrive electric wire field more particularly to a kind of telephone wire crystal head.

Background technology

Telephone wire is exactly the house lead in of phone, is connected on telephone set, can just be made a phone call, telephone wire include telephone wire with Crystal head, one end of crystal head are connected to Telephone set, and the other end is connected to hub, and crystal head uses bayonet lock or bullet mostly Crystal head is fixed in the cooperation of piece, but when installing telephone wire, is needed to install crystal head, only needed bullet when installing crystal head Piece is directly inserted into crystal head in phone card slot, but during dismounting crystal head, it is necessary to it pushes shrapnel to be torn open always It removes, it is primary without removing successfully, it is also necessary to repeatedly to push shrapnel and be removed, not convenient enough, repeatedly pushing shrapnel can make Obtaining the elastic-restoring force of shrapnel reduces, and the service precision and service life for making crystal head decline.

Utility model content

The utility model lies in that providing a kind of telephone wire crystal head, solve the prior art and need to push shrapnel always It is removed, it is primary without removing successfully, it needs repeatedly to push shrapnel and be removed, not enough facilitate, repeatedly push shrapnel It can cause the elastic-restoring force of shrapnel to reduce the problem of declining so as to cause the service precision and service life of crystal head.

Technical solution described in the utility model is as follows：A kind of telephone wire crystal head, includes telephone wire and crystal head, crystal Head is connected to Telephone set and hub, and the crystal head includes pedestal and shrapnel, and shrapnel is fixedly connected on pedestal On, it is characterised in that：Card slot is provided on the pedestal, the buckle protrusion being adapted with card slot, the bullet are provided on shrapnel Piece can be close to and be detached relative to pedestal by the protrusion that is buckled, and the outer surface of the shrapnel is provided with wearing layer, the card The outer surface of button protrusion is provided with the ferro-gum being adapted with card slot shape size, and the bottom of card slot and surrounding are filled with magnetic Iron.

The utility model is further arranged to：The diameter of the buckle protrusion is less than the diameter of card slot.

The utility model is further arranged to：There is elasticity relative to card slot side wall and squeeze in the ferro-gum.

The utility model is further arranged to：When shrapnel is tightly attached to pedestal, buckle protrusion is located in card slot.

The beneficial effects of the utility model：1 when using the utility model, it is only necessary to press shrapnel, shrapnel will pass through Magnet in card slot is mutually adsorbed with the ferro-gum in buckle protrusion, and shrapnel is fixed on pedestal, bullet will not be come up again, this When can be carried out removing crystal head, easy to operate, primary pressing can remove success, not need to push shrapnel always, need When using shrapnel, it is only necessary to dial up shrapnel and may be such that shrapnel is detached with pedestal, the utility model is solved because repeatedly It pushes shrapnel so that the elastic-restoring force of shrapnel reduces, so as to reduce the service precision of crystal head and service life.

Fig. 3 is crystal head using state structure diagram in Fig. 2.

Figure label meaning is as follows：1- crystal heads；2- telephone wires；3- buckle protrusions；11- pedestals；12- shrapnels；111- cards Slot；112- magnet；121- wearing layers；31- ferro-gums.

Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is used to illustrate the utility model, but be not intended to limit the scope of the present invention.

Specific embodiment of the present utility model is described in detail to Fig. 3 in complex chart 1, a kind of telephone wire crystal head, including There are telephone wire 2 and crystal head 1, crystal head 1 is connected to Telephone set and hub, and the crystal head 1 includes pedestal 11 and shrapnel 12, shrapnel 12 be fixedly connected on pedestal 11, it is characterised in that：Card slot 111, shrapnel are provided on the pedestal 11 The buckle protrusion 3 being adapted with card slot 111 is provided on 12, the shrapnel 12 can relative to pedestal 11 by being buckled protrusion 3 Be close to and detach, the outer surface of the shrapnel 12 is provided with wearing layer 121, the outer surface of the buckle protrusion 3 be provided with The ferro-gum 31 that 111 shape size of card slot is adapted, the bottom of card slot 111 and surrounding are filled with magnet 112, the buckle The diameter of protrusion 3 is less than the diameter of card slot 111, and the ferro-gum 31 has elasticity relative to 111 side wall of card slot and squeezes, and works as bullet When piece 12 is tightly attached to pedestal, buckle protrusion 3 is located in card slot 111.

A kind of telephone wire crystal head described in above structure, when needing to remove the crystal head on telephone wire, it is only necessary to Press shrapnel 12, the buckle protrusion 3 on shrapnel 12 will be sticked among card slot 111 so that shrapnel 12 will not bullet come up, Neng Goufang Just crystal head 1 is taken down, when needing installation, it is only necessary to shrapnel 12 is dialed up, due to being provided with ferro-gum in buckle protrusion 3 31,111 bottom of card slot and surrounding are provided with the magnet 112 to cooperate with ferro-gum 31, so buckle protrusion 3 and card slot By the way that mutually buckle protrusion 3 and the fixation of card slot 111 are realized in absorption between ferro-gum 31 and magnet 112 between 111, dial upwards Spring plate 12 causes the increase of the distance between ferro-gum 31 and magnet 112, so that magnetic disappearance between the two, i.e. bullet Piece 12 revert to origin-location.

A kind of telephone wire crystal head described in above structure, the outer surface of shrapnel 12 is provided with wearing layer 121, multiple During plug crystal head 1, the outer surface of shrapnel 12 and the contact site friction for being used for the slot for installing crystal head 1 are the most serious, Prolonged friction can also reduce the service life of shrapnel 12, can be effective so being provided with wearing layer 121 in the utility model Reduce friction, so as to increase the service life of shrapnel 12 and service precision.

The utility model only needs simple operations when user needs to remove crystal head 1, and primary pressing can quickly be torn open Remove, will not be because repeatedly pushing shrapnel 2 so that the elastic-restoring force of shrapnel 2 reduces, so as to reduce the service precision of crystal head 1 with And service life.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, under the premise of the utility model technical principle is not departed from, several improvement and modification, above-mentioned vacation can also be made If these improvements and modifications also should be regarded as the scope of protection of the utility model.
