Description

The structure-improved of telecommunication terminal box

The utility model relates to a kind of telecommunication apparatus, is meant a kind of telecommunication terminal box especially.

Along with the communication development of science and technology, the situation of an original line one phone becomes history already, utilizes the telecommunication terminal box can make a line one phone conversion being aligned loquacity machine, with more convenient to use and can make full use of limited information network.But the frame mode of the telecommunication terminal box of commonly using is comparatively simple and crude, and result of use is not attained perfect.The telecommunication terminal box inner lead of commonly using and the composition of conducting terminal, wearing out the wire insulation crust by the salient point on the conducting terminal sheet contacts with internal wire, the contact of this kind mode is very not good, conductive effect is not good, moreover, outer conductor is not because of there being fixed support, the time and pullled by external force and off-line, broken string, directly influence the quality of telecommunication apparatus.

Therefore the inventor is the Given this long-pending rich experiences of being engaged in such product design, manufacturing for many years, actively drop into that a large amount of mental and physical efforts are studied and after experiment repeatedly, the utility model is successfully proposed eventually, its purpose be to improve the telecommunication terminal box conductive effect, prevent the artificial improper and off-line of outer conductor, drop; The box body inside conductor distributes in order, and the reason termination contact does not cause short circuit.

The purpose of this utility model is achieved in that a kind of structure-improved of telecommunication terminal box, include protecgulum and bonnet, be equiped with lead and conducting terminal in it, it is characterized in that described protecgulum is provided with a jack, this jack is provided with a movable over cap, and this over cap is plugged on the conduit of protecgulum inside, is provided with a frame post at the back side of jack, one wire support patchhole is arranged on this frame post, and the outer conductor support inserts in it; These frame post both sides respectively are provided with groove and separate plate, and this separates, and plate is other to be provided with the alignment post, separate to be bordering on alignment post place on the plate and to be provided with scarce hole; The alignment post is provided with screw, and L type conducting terminal is fixed in it; The bottom surface and the side of bonnet are provided with thin plate, push away brokenly this thin plate and can form a through hole in this place, and the inboard of bonnet is provided with a H type card terminal, and outer conductor is fastened on this H type card terminal.

The utility model can be realized that also the lower end that is inserted in the over cap on the inner conduit of protecgulum is provided with a tension spring by following measure; The frame post and the protecgulum at the jack back side is one-body molded on the protecgulum; The top of the wire support patchhole on the frame post be provided with insert the metallic object lead every the road; Lead is laid in the groove that separates between plate and wire column; Protecgulum is provided with preposition hole, by the screw in the hole itself and bonnet is connected to a box body; The end of L type terminal is a ring circle; It is six line formulas or eight line formulas that the protecgulum jack can cooperate the plug of the end of incoming call line.

After lead divests insulated hull in the utility model, coat by two fins with L type terminal, make L type conducting terminal and lead firm engagement, when the ring circle of L type terminal contacts with outer conductor, preferable conductive effect is arranged, when outer conductor is worn out the thin plate of side thin plate or bottom and entered in the terminal box, be fastened in the card terminal, on make it under the situation of improper external force, unlikely coming off; In addition lead is docile and obedient preface and is laid in frame post and the groove that separates in the plate, makes its unlikely messy, terminal be difficult for causing short circuit because of contact; The circular hole of this conduction L type terminal ends in use is difficult for landing by screw fixings on the alignment post in addition.
