Embodiment
Wire-connecting device 1 according to the embodiment of the invention will make an explanation referring to figs. 1 to 6.
In Fig. 1 to 4, wire-connecting device 1 comprises coaxial cable 10, lead 20, tab terminal 30, ground plate 40, but and in order to coaxial cable 10 and lead 20 thermal contraction parts 50 connected to one another.
This to base portion 412a, 412b from the edge of fixed part 43 along A direction vertical extent.This is narrower and extend from base portion 412,412 than base portion 412,412 to crimping piece 413,413.Subsidiary one carries, and in the present embodiment, crimping piece 413,413 misplaces each other, thereby is not in contact with one another.Therefore, when this gauze 12 of crimping, the contact area between gauze and the crimping piece 413,413 is big, and this gauze 12 is ground connection effectively.
Connecting portion 411, this makes by the metallic plate that compacting is used for fixing portion 43 crimping piece 413,413 base portion 412,412 and this, as crimping or keep the terminal of gauze 12.
Each clamping part 42,42 comprises extension 421, a pair of base portion 422,422, a pair of grip block 423,423 and recess 424.Each extension 421 is connected in fixed part 43 and extends from the edge of fixed part 43.
This to base portion 422,422 from the edge of fixed part 43 along A direction vertical extent.This is narrower than base portion 422,422 to grip block 423,423 and extends from this base portion 422,422.Subsidiary one carries, and as pressure contact portion 41, grip block 423,423 misplaces each other, thereby is not in contact with one another.Therefore, crimping coating 14,22 o'clock, the contact area between coating 14,22 and the grip block 423,423 was big, and coaxial cable 10 and lead 20 be ground connection effectively.
Each recess 424 forms near the U-shaped otch the grip block 423.Subsidiary one carries, and recess 424 can form different shape, for example V-arrangement or square.In addition, in the present embodiment, recess 424 is formed on the roughly rectangular position, angle between base portion 422 and the grip block 423, is used to prevent shear.Yet recess 424 can be formed on obtuse-angulate position, this angle.Thereby when grip block 423 crimping, recess 424 prevents that base portion 422 from shearing.Therefore, crimping pressure can reduce and the crimping system can dwindle.
Shown in Fig. 3 and 4, the interval L between base portion on the A direction 422,422 is narrower than the width W of fixed part 43.Therefore, when grip block 423 crimping, base portion 422 prevents fixed part 43 distortion.
Subsidiary one carries, in the present embodiment, and coating 14 and one of clamping part 42 crimping, coating 22 and another clamping part 42 crimping.Yet, but thermal contraction part 50 is crimped, but maybe can being set, another clamping part 42 is used for this thermal contraction part 50 of crimping.
Fixed part 43 for example forms roughly square by compacting conductive metal plate.Hole 43a is formed on the centre of fixed part 43, is used for the unshowned screw of fixed part 43 usefulness in for example car body, so that fixed part 43 and pressure contact portion 41 ground connection.
But but thermal contraction part 50 is the insulation heat-shrinkable tube, and its inside comprises hot-melt adhesive.But should burst forth in order to prevent the gauze 12 that is exposed to tab terminal 30 by thermal contraction part 50, cover the side cut 12a and the tab terminal 30 of gauze 12, and do not cover the position of pressure contact portion 41 crimping.
But thermal contraction part 50 is transparent.Therefore, even but when thermal contraction part 50 covering side cut 12a and tab terminals 30, they also are visible, and the wire-connecting device 1 that defective wire-connecting device 1 for example disconnects can be eliminated.Because but thermal contraction part 50 covers side cut 12a, so folding gauze 12 is nonessential, thereby can reduce manufacturing cost.
But the bonding strength between thermal contraction part 50 decision coaxial cables 10 and the lead 20.Therefore, but but thermal contraction part 50 can come control connection intensity by the type or the size that change thermal contraction part 50.In addition, but because the existence of thermal contraction part 50, welding is nonessential for fixed part 43.Therefore, can reduce manufacturing cost and environmental pollution.
Next the embodiment of this wire-connecting device 1 is assembled in explanation.At first, inner wire 11 and heart yearn 21 are arranged on the tab terminal 30 Face to face.Then, this tab terminal 30 of crimping, thus coaxial cable 10 and lead 20 are electrically connected each other.
As shown in Figure 1, combination 2 is made up of coaxial cable 10 and lead 20, but the two covers by thermal contraction part 50.But this combination 2 is made by heating thermal contraction part 50, but should cover gauze 12, heart yearn 21, coating 22 and the tab terminal 30 that is positioned at side cut 12a place by thermal contraction part 50.
As shown in Figure 5, pressure contact portion 41 and clamping part 42,42 are arranged on the anvil 81 of terminal crimping machine (not shown).Subsidiary one carries, well-known, in the terminal crimping device, curler 82 is depressed to anvil 81 so that crimping piece 413,423,423 is crimped on coaxial cable 10 and lead 20.
In the present embodiment, combination is arranged on the ground plate 40, thereby but is positioned on the pressure contact portion 41 from the gauze 12 that thermal contraction part 50 comes out.Then, depress curler 82 gauze 12 is crimped on pressure contact portion 41 and coating 14,22 is crimped on clamping part 42,42.
Subsidiary one carries, and in the present embodiment, pressure contact portion 41 is arranged near one of them edge of fixed part 41.Yet the present invention is not limited only to this.This pressure contact portion 41 can be inserted in the optional position between the clamping part 42,42.
Fig. 6 is the schematic diagram of pressure contact portion 41 with respect to the position of fixed part 43.For fear of repetition, same parts will be represented and only illustrate with the foregoing description to compare difference by same Reference numeral.
As shown in Figure 6, pressure contact portion 41 is inserted in and this pressure contact portion 41 has between the clamping part 42,42 of same distance L1.Therefore, but be arranged on central authorities between the clamping part 42,42 of fixed part 43 from the gauze 12 that thermal contraction part 50 exposes.Therefore, combination 2 easily is located on the fixed part 43.
Therefore, the assembling flexibility is improved.For example, combination 2 can oppositely be arranged on the ground plate 40.In addition, the type of ground plate 40 can reduce and the versatility of ground plate 40 can be improved.Therefore, manufacturing cost can reduce.Subsidiary one carries, if pressure contact portion 41 is inserted in the central authorities between two edges 43a, the 43b, does not also have any problem for pressure contact portion 41.
In addition, in the present embodiment, pressure contact portion 41 and clamping part 42,42 these three parts are used for this combination 2 of crimping.Yet the quantity of clamping part 42 can increase and decrease.
In addition, in the present embodiment, the size of clamping part 42,42 differs from one another.Yet this size also can be identical.Thereby the versatility of the design flexibility of combination 2 and wire-connecting device 1 is improved.
In addition, in the present embodiment, but the external diameter of coaxial cable 10 and thermal contraction part 50 can be identical in certain error range.In this case, the crimping condition that is used for two clamping parts 42,42 is identical, and the combination of anvil 81 and curler 82 only is two kinds.Therefore, the versatility of maintainability and wire-connecting device 1 is improved.
In addition, in the present embodiment, adopt lead.Yet the present invention is not limited only to this.Can adopt various coaxial cables.In this case, but thermal contraction part 50 covers two side cut 12a of coaxial cable gauzes 12.
Though the present invention has carried out abundant description by means of the example with reference to appended accompanying drawing, is understandable that variations and modifications are conspicuous to those skilled in the art.Therefore, unless these variations and modification break away from the present invention's institute's restricted portion hereinafter, otherwise they will be believed to comprise therein.
