Description

Double-layer plate type wire connection device

The utility model relates to the communication electric wire termination that communication line etc. is electrically connected usefulness, particularly relate to can reduce the connection stress that in the process that connects the communication electric wire, taken place, and can be to having the double-deck board-like termination that the communication electric wire of major diameter scope is electrically connected very much.

Usually the termination used of communication line mainly adopts screw-type termination and crimping (insulation displacement) formula termination.In addition, usually the termination used of communication line must be applicable to the communication electric wire of diameter of wire the user of 0.4mm-1.0mm simultaneously, and the communication electric wire used in the telecommunication bureau of 0.4-0.5mm of diameter of wire.Above-mentioned screw-type termination is mainly used in the voice communication field, in non-sound (numeral) communication field, because it has reduced transmission characteristic widely and can not use.Different therewith, above-mentioned compression joint type termination has been eliminated the shortcoming of above-mentioned screw-type connection plug, can use in non-voice communication and sound communication field.In addition, above-mentioned compression joint type termination is when the maintenance and repair circuit, have to make the wiring of communication line easy, and cheap advantage., existing compression joint type termination is because it does link slot very widely according to large diameter communication electric wire, so exist the problem of the communication electric wire that can not reconnect minor diameter.Owing to there are the problems referred to above, when using existing compression joint type termination to reconnect communication line, have the communication electric wire of special limited range except only adopting, there is not other way.1 the problem that above-mentioned existing compression joint type termination exists is described with reference to the accompanying drawings.

Existing compression joint type termination shown in Fig. 1 has conductive plate 10, has made the first and

second contact grooves

12,14 that carry out electric contact respectively with the communication electric wire that is connected on it.

Contact grooves

12,14 for the communication electric wire being imported above-mentioned first and second, and divest the insulating barrier of above-mentioned communication electric wire, on above-mentioned conductive plate 10, made four and imported the 16A of inclined side portion, 16B, 18A, the 18B that electric wire is used.

The existing compression joint type termination of above-mentioned structure with the inclined side 16A of portion, 16B, 18A, 18B, automatically divests the insulating barrier that inserts the communication electric wire in the first and

second contact grooves

12,14 by means of four importings, and the wiring process of communication line is simplified.And existing compression joint type termination is made with a conductive plate, has advantage of low manufacturing cost., formed above-mentioned contact groove on existing compression joint type termination, as contacting for a long time with communication electric wire with large diameter lead, can because and the contact stress between the communication electric wire make increase at interval.Because above-mentioned contact groove increases,, and make the connection of communication electric wire also become unstable so existing compression joint type termination can not connect the communication electric wire with small diameter wire when re-using.So existing compression joint type termination can only connect the conditional especially communication electric wire of diameter when reusing.

Therefore, the purpose of this utility model provides the board-like termination of a kind of bilayer, and it can prevent to produce contact stress, and can repeatedly repeat wiring to the communication electric wire of lead with very wide diameter category.

For achieving the above object, the board-like termination of bilayer of the present utility model has following parts: top have for importing comprising the communication electric wire lead and the electric wire that imports fixedly the first contact groove of usefulness first conductive plate, above have for importing comprising the communication electric wire lead and the electric wire that imports fixedly the second contact groove of usefulness second conductive plate, be used for contacting the contact stress that groove produces to above-mentioned first and pass to above-mentioned second conductive plate, one side, and contact the stress distribution device that the contact stress that produces in the groove passes to above-mentioned first conductive plate, one side to above-mentioned second.

And in the board-like termination of described bilayer, above-mentioned stress distribution device comprises the first and second stress dispersion trains that connect upper end, the above-mentioned first and second conductive plate both sides.

And, in the board-like termination of described bilayer, above-mentioned first conductive plate and second conductive plate, and the first and second stress dispersion trains are as a whole.

And in the board-like termination of described bilayer, the above-mentioned second contact groove contacts the bigger communication electric wire of diameter of wire of the communication electric wire in the groove in order fixedly to have than being fixed on first, and has bigger interval.

And in the board-like termination of described bilayer, above-mentioned first conductive plate also has the 3rd contact groove that contacts the groove same intervals with above-mentioned first.

Embodiment of the present utility model is described with reference to the accompanying drawings.
