Abstract

The utility model relates to a connecting device for the insulated conducting wires of local communication cables, comprising a base, a front and a back clamping blades connected together and an upper cover. Guiding pipe holes are arranged on the base, and wire clamping slots are arranged on the clamping blades. The utility model is characterized in that the widths of the wire clamping slots on the front and the back clamping blades are different. The bottom parts of the guiding pipe holes corresponding to the wire clamping slots are provided with protruding denticles. The wiring connector with reliable connection and low price is suitable for various cable wire diameters.

Description

Universal button type contactor

The utility model is a kind of for the city communication cable insulated conductor communication line of the usefulness device that continues that continues.

The button connector is the device of using always in city communication cable in recent years that continues.But current general button connector, because the width of the cable clamping interface on two the clamping cuttves card of front and back is identical, therefore narrower with a kind of connector to the accommodation in the line footpath of the insulated conductor that can continue, and this class button connector is because insulated conductor can't enter putting than deep-seated of cable clamping interface, thereby under the thinner situation in online footpath, often pull easily; Moreover, because the guiding pore is shorter, carelessness is arranged slightly the time in construction, interior then one will empty calorie the clamping blade, make continue unreliable.So far this class button connector generally all make of polycarbonate, so its material cost is also higher.

The purpose of this utility model is exactly to make the cable that can be applicable to multiple line footpath with a kind of connector, and continue more reliable, cost is cheaper.

Universal button connector described in the utility model, form by loam cake, base and two clamping blades in front and back of linking to each other, on base, have and wear two guiding pores that insulated conductor is used, on two clamping blades, two cable clamping interfaces and central channel are arranged respectively, its key is that the width of the cable clamping interface on two the clamping blades in front and back is inequality, and with the corresponding bottom of cable clamping interface protruding little tooth is arranged on the guiding pore.

This Universal button connector can not only be applicable to the cable in various lines footpath, and because the existence of protruding little tooth, can be more in depth being headed in the cable clamping interface by the cable core of clamping, it is more reliable that it is continued.If think certainly to there is no need to enlarge the scope of application, then the width of the cable clamping interface on the two clamping blades of front and back also can be made identical.

Fig. 1 is a side sectional view of the present utility model, and Fig. 2 is a front view, and 1 is that base, 2 is loam cake, 3 and 4 two clamping blades in front and back for linking to each other; Cable clamping interface 5 and 6 and central channel 19 are arranged on preceding clamping blade 3, on back clamping blade 4, cable clamping interface 7 and 8 and central channel 20 are arranged; 9 and 10 are the guiding pore, 11,12 and 13,14 on the guiding

pore

9 and 10 with the protruding little tooth of cable clamping interface 5,6 and 7,8 corresponding bottoms.

As embodiment, the cable clamping interface 5 of preceding clamping blade 3 and 6 width are (0.37～0.43) mm, and the cable clamping interface 7 of back clamping blade 4 and 8 width are (0.23～0.27) mm, and its protruding little tooth 11,12,13 and 14 is leg-of-mutton.Like this, the thicker cable core in line footpath is continued, guarantee its fracture load, guarantee to continue reliable by back clamping blade 4 by preceding clamping blade 3; The thinner cable core in line footpath is continued, and then clamping blade 4 is guaranteed to continue reliably and pulling-out force later on.Because the existence of protruding little tooth 11,12 and 13,14 is arranged, at clamping blade 3 and 4 downwards during card, can be

cable core

17 and 18 more deep heading in cable clamping interface 5,6 and 7,8, make continue more reliable.In order to ensure the bounce pressure of clamping blade, also be provided with the little tooth 21 of triangle and 22 on the guiding pore with on central channel 19 and the 20 corresponding positions.Because above-mentioned measure has been arranged, so this connector can adopt polypropylene to form, and needn't use polycarbonate, can meet the demands equally, and make its cost lower.

May not arrive worn-out sick under the back clamping blade 4 for fear of cable core, in an

embodiment guiding pore

9 and 10 is prolonged backward, allow its top 15 and 16 stretch out outside the line of the outer garden of loam cake 2.

Claims
