Description

The cable cores card that continues

The utility model relates to the cable core jockey, refers to a kind of cable cores card that continues particularly.

At present, cable core continues particularly that continuing of local cable heart yearn mainly contains three kinds of diverse ways.First kind of method that continues is the method for twisting joint, and the instrument of its use is the pincers that continue, i.e. the pliers of a kind of special use, and the equipment that continues that uses is paper or plastic bushing.Earlier sleeve pipe is inserted on the heart yearn when continuing, make two heart yearns to be continued in accordance with regulations size carry out wire stripping, intersection, twisting, wipe out surplus line, push sleeve pipe to the junction at last.This connecting method program is loaded down with trivial details, efficient is low, to operating personnel's specification requirement height.And the naked core line that must pinch after peelling off insulating barrier owing to staff when heart yearn is twisted joint just can be twisted joint, so this link easily makes the naked core line be stained with the sweat on the staff and corroded.Second kind of method that continues is the connector method, and equipment and instrument that this method is used are connector and Press Plier.Its process that continues mainly is twisting, trimming, heart yearn is inserted four processes such as connector hole, crimping.The deficiency that this method exists is that the efficient that continues is low, and the joint volume is big, is not suitable for big capacity and continues.The third method that continues is that the handshaking procedure of module press-connection machine crimping method, this method roughly is plurality of processes such as separated time, install machinery, winding displacement, pressurization.This method efficient height that continues is fit to large-scale construction, and weak point is an apparatus expensive, and volume is big, carries inconvenience, can not the one man operation, be not suitable for continuing of little logarithm cable, and the construction equipment is also more expensive, and not too economical.

The purpose of this utility model will overcome the above local cable heart yearn existing deficiency that continues exactly, provide a kind of structure small and exquisite simple, that operation is implemented is convenient, the high cable cores of the timeliness that continues continues card.

For realizing this purpose, the designed cable cores of the utility model card that continues is combined by terminal board, terminal base and some binding posts.Terminal board is long and narrow strip structure, has a long and narrow rectangular through-hole in the middle of it, and designing separately symmetrically on its upper and lower surface edge has two row's pectination double wedges, and the space between each adjacent pectination double wedge constitutes the inlet wire groove of the cable core that will continue.Terminal base is long and narrow square type structure, is embedded in the middle narrow and long rectangular through hole of terminal board, and designing respectively on its long and narrow two side walls has row's convex tendon, and the space between each adjacent convex tendon constitutes the terminal position groove.Binding post is fine strip shape disjunctor double-pole mouth structure, be fixed between the wall of each terminal position groove and narrow and long rectangular through hole, it has up and down designed a wire-clamping knife groove respectively in two ends, and the residing position of wire-clamping knife groove is corresponding with the position of the groove of inlet wire up and down on the terminal board just up and down.Utilizing existing H-100 type or other similar wire-clamping knife tools directly heart yearn to be snapped onto in the wire-clamping knife groove of binding post when continuing cable core gets final product.

Advantage of the present utility model is: the whole card that continues is only formed by three kinds of parts reasonable combination, and cable core continues mutually by two wire-clamping knife grooves up and down of a binding post, and its volume is little, and is in light weight, simple and compact for structure, with low cost.Its method of operation becomes clamping by twisting joint of past, and the time that the time ratio of card line is turned round line shortens dramatically, and reformed links such as twisting in the program that continues in the past, poling, trimming simultaneously, thereby it is easy to use, and the timeliness that continues significantly improves.And staff can not contact exposed heart yearn in handshaking procedure, has avoided the erosion of sweat to heart yearn, and connecting quality is very solid and reliable.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Fig. 1 is the continue front view of card of a kind of cable cores;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the left view of Fig. 1;

Fig. 4 is the terminal board front view of the card that continues shown in Figure 1;

Fig. 5 is the vertical view of Fig. 4;

Fig. 6 is the left view of Fig. 4;

Fig. 7 is the terminal base front view of the card that continues shown in Figure 1;

Fig. 8 is the vertical view of Fig. 7;

Fig. 9 is the left view of Fig. 7;

Figure 10 is the binding post schematic diagram of the card that continues shown in Figure 1.

Be 30 pairs the cable cores card that continues shown in the figure, by terminal board 1, terminal base 8 and 60 binding posts 4 constitute.This terminal board 1 is long and narrow strip structure, and its two ends has had the holddown groove 5 and the fixing hole 6 of the effect of installing and fixing.Have a long and narrow rectangular through-hole 10 in the middle of it, rectangular through-hole 10 inwalls are provided with flange 13.Design separately symmetrically on its upper and lower surface edge two row's pectination double wedges 2 are arranged, space between each adjacent pectination double wedge 2 constitutes the inlet wire groove 9 of cable core, the original position of per ten pectination double wedges 2 is provided with a sequence number sign 3, so that cable core guiding, ordering, colligation are fixed.

This terminal base 8 is long and narrow square type structure, and its two side walls is provided with oblique flange 14, and this oblique flange 14 is embedded in the narrow and long rectangular through hole 10 of terminal board 1 centre terminal base 8 with above-mentioned flange 13 actings in conjunction securely.Also designing respectively on the two long and narrow side wall surfaces of terminal base 8 has the cross convex tendon 11 of a row, and the space between each adjacent cross convex tendon 11 constitutes terminal position groove 12.The mid portion of terminal base 8 is designed to the hollow structure of tool and the long narrow square opening 7 of a row, and this mainly is in order to save material, and weight reduction makes overall structure light and handy.

This binding post 4 is fine strip shape disjunctor double-pole mouth structure, it has designed a wire-clamping knife groove 15 respectively in two ends up and down, wire-clamping knife groove 15 roots respectively have a springhole 17 up and down, the design of the dual-side of wire-clamping knife groove 15 is 5～15 ° angle up and down, design has a pair of inwardly recessed locating notch 16 in the middle of the binding post 4, such planform can make binding post 4 have better elastic distortion and reset capability, can easily the outer protective sleeve of cable core be cut, heart yearn can not cut off again, guarantee that connecting quality is solid and reliable.Above-mentioned binding post 4 is installed between the wall of each terminal position groove 12 and narrow and long rectangular through hole 10 one by one, the minor face of cross convex tendon 11 just in time contract is gone in the locating notch 16 of binding post 4, limit it and move up and down, this moment, the groove of the wire-clamping knife up and down 15 residing positions of binding post 4 were just corresponding with the position of the groove of inlet wire up and down 9 on the terminal board 1.

Easy to operate easy of the card that continues described in the utility model, it is firm that the heart yearn that continues is stablized, cable core Logarithm, well arranged, neat appearance are convenient to search, and have compared with prior art greatly shortened when continuing Between, applicable to all-plastic cable and paper the continuing every cable of various lines to 0.32～0.70mm wire diameter.
