Description

Conductor jointer

Technical field

The utility model relates to a kind of circuit connection fittings, relates in particular to a kind ofly to be used to connect lead, to realize the conductor jointer that lead electrically connects.

Background technology

In the application process of detonator, different cloth hole designs is to the length requirement difference of detonator payment to a porter.Recommendatory regulation payment to a porter length is taken as 2m among the GB GB8031-2005, and this regulation can satisfy the demand of most conventional explosion.But, for the special blasting type, for example deep hole blasting, the long payment to a porter of 2m just can't be satisfied the requirement that explosion is arranged net, and at this moment often needs to customize the detonator of special requirement, thereby makes troubles for production management.Therefore, also can adopt at the blast working scene mode that prolongs payment to a porter according to different demands to address this problem.

In the mode that electrically connects between common realization lead, the most frequently used way is that insulating barrier is peelled off, core be screwed in together or weld together to realize electrically connecting between lead, at last with insulating tape with terminal part and exposed part parcel, to realize and extraneous insulation.But, adopt not only inefficiency of this method, and make mistakes easily and cause line short.In addition, adopt insulating tape with core blank area parcel, blank area is prone to short circuit phenomenon in wet environment, thus damaged circuit.

Can also adopt the binding post of screw crimping mode to realize conducting between lead.To wait earlier during wiring that the insulating barrier that connects wire termination divests, the lead core that will expose again is wrapped on screw or the double-screw bolt, or inserts wiring hole, screws screw or nut then and pushes down lead core formation joint realization conducting.The operational sequence of this implementation is more loaded down with trivial details.When the butted line reliability requirement was higher, operator's technical merit also may influence the quality of joint.In addition, this mode must be by metalwork---and the electric conductivity of screw could be realized electrically connecting.

A kind of fast-wiring is disclosed in the application documents of patent ZL93205872.8, in order to realize fast-wiring.The involved clamping technical scheme of this patent is by metal card contact pin with can drive lead and snap in a kind of lead clamping apparatus that the housing of metal card contact pin and base etc. constitute and realize by a kind of.Similarly, the related technical scheme of this patent also must could realize electrically connecting between lead by metalwork.

The defective of these schemes that realization electrically connects by metalwork is: in the design of above-mentioned binding post and connector, except that metalwork, other are made by insulating material as parts such as housing, bases, for example rubber, plastics etc., and the reliable bonding of material of rubber, plastics and so on and sheet metal is difficult to realize, this just makes troubles for the processing of connector.

Summary of the invention

The utility model, that is a kind of conductor jointer based on following technical scheme and advantage thereof, solve above-mentioned defective.

Provided by the utility model in order to realize the conductor jointer that electrically connects between the lead, comprise cavity and with this cavity at the button that matches in shape, and this button and cavity constitute by insulating material.The cavity bottom of this conductor jointer is distributed with one or more grooves that are isolated from each other, and perpendicular to being distributed with one or more holes on the axial chamber outer wall of groove, each hole is passed chamber outer wall and extended to and the corresponding groove in this hole, forms a guide groove; The core of lead enters and the corresponding groove of this guide groove along guide groove, and pressing button enters in the cavity, makes all cores that are in the groove be in contact with one another in this groove, and formation electrically connects.

The benefit of technique scheme is: this conductor jointer is made of insulating material fully, need not just can realize electrically connecting between the lead by the indirect electric action of metalwork, has both realized reliably electrically connecting, and has made things convenient for the processing of connector again.

One of preferred version of the present utility model is that the width of above-mentioned groove is greater than or equal to the diameter of each core that enters this groove, and less than the diameter sum of all cores that enter this groove.So just can guarantee that each core that enters same groove can contact with each other under the effect of pushing of button, thereby realize electrically connecting reliably.

Another preferred version of the present utility model is, with the parallel to each other but disalignment of the corresponding all guide grooves of above-mentioned groove, thereby it is parallel to each other and stagger to enter all cores in this groove via these guide grooves.If do not adopt this scheme, all cores may be because of interaction bends in entering the process of groove, thereby when pressing button enters cavity, has the possibility that can't overlap between all cores, thereby what may cause electrically connecting is unreliable, even can't realize electrically connecting.In addition, in the utility model, inject thick insulating material in the cavity of conductor jointer, can play the effect of insulated enclosure, thereby can avoid the influence of extraneous wet environment, the reliability that helps electrically connecting such as epoxy resin.

Embodiment

Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is described in further details.

Conductor jointer 1 shown in Figure 1, comprise cavity 10 and with this cavity 10 at the button 2 that matches in shape, and button 2 and cavity 10 constitute by insulating material.In the bottom of cavity 10 groove 16 is arranged, referring to shown in Figure 2.The outer surface A of cavity 10 is axial vertical with groove 16.A hole 14 is arranged on this outer surface A, and the outer wall of cavity 10 is passed in this hole 14, extend to this hole 14 corresponding grooves 16 in, form a guide groove 18 ', referring to shown in Figure 3.On another outer surface A ' parallel with outer surface A a hole 15 is arranged also, similarly, the outer wall of cavity 10 is passed in this hole 15, extends in the corresponding groove 16, forms a guide groove 18, as shown in Figure 4.The core of lead 3 is along guide groove 18 ' enter in the groove 16, the core of lead 4 enters in the groove 16 through guide groove 18, form state as shown in Figure 4, then when pressing button 2 enters in the cavity 10, be in two core generation deformation in the groove 16, and will in groove 16, be in contact with one another, form state shown in Figure 5, so far realized electrically connecting of lead 3 and lead 4.

Deformation takes place in the lead core in groove 16, help improving the ability that lead bears the external pull effect, even therefore there is the effect of external tensile force, the lead that is in the groove 16 can not come off easily yet, and this has just further improved the reliability that electrically connects.

For making the core that enters groove 16 to realize more reliably electrically connecting, the width d of groove 16 can be obtained the diameter that is greater than or equal to each core that enters this groove 16, less than the diameter sum of all cores that enter this groove 16, referring to shown in Figure 2.So just can guarantee that each core that enters same groove can contact with each other under the effect of pushing of button, thereby realize electrically connecting reliably.

In addition, also can on button 2, design shape and the big or small projection 20 that all is complementary with groove 16, as shown in Figure 2, after making that button 2 is pressed into cavity 10, projection 20 enters groove 16, the lead core tightly is pressed into, and the space in the groove 16 is almost taken, this helps improving the dependability of the utility model connector.

As shown in Figure 4, for making all cores in the process that enters groove 16, not bend because of interaction, will with groove 16 corresponding guide grooves 18 and guide groove 18 ' design parallel to each otherly but disalignment, this core that just can guarantee lead 3 and lead 4 staggers after entering groove 16 each other.And, as can be seen from Figure 4, the staggering of lead 3 and lead 4 apart from d ₁Radius sum more than or equal to these two strands of lead cores.Thereby, when pressing button 2 enters cavity 10, can reliably overlap between core, referring to shown in Figure 5, so the reliability that helps electrically connecting.

When in the networking of multi cord connects, using above-mentioned conductor jointer embodiment illustrated in fig. 1, can adopt a plurality of conductor jointers 1 to realize the connection of circuit one by one respectively.If conductor jointer of the present utility model will be directly applied to the connection of multi cord, then can make following change: on basis embodiment illustrated in fig. 1 to embodiment illustrated in fig. 1, on the outer surface A of cavity 10 and A ', a plurality of holes are set respectively, a plurality of grooves that are isolated from each other 16 are set in the bottom of cavity 10, and can on button 2, be provided with groove 16 shape, size and quantitatively all be complementary a plurality of protruding 20, make it tight contact in order to compress core.

With embodiment shown in Figure 6 is example, and conductor jointer 11 is in order to realize electrically connecting respectively of two strands and two strands.As Fig. 6, the outer surface A of the cavity 10 of conductor jointer 11 is provided with hole 21 and hole 22, and outer surface A ' is provided with hole 23 and hole 24, the bottom of cavity 10 be provided with two

grooves

16 and 16 '.Wherein, hole 21 and hole 23 extend in the groove 16 via

guide groove

31 and 33 respectively, hole 22 and hole 24 respectively via

guide groove

32 and 34 extend to groove 16 ' in, as shown in Figure 8.And groove 16 is isolated with the groove 16 ' interlayer 17 that passes through to insulate, referring to shown in Figure 7.So just can guarantee accurately to enter in the groove 16 via the lead core that hole 21 and hole 23 enter in the cavity 10, similarly, via hole 22 and hole 24 enter lead core in the cavity 10 accurately enter groove 16 ' in.This had just both realized electrically connecting of two strands simultaneously, had avoided the short circuit of circuit again.With above-mentioned two grooves 16 and 16 ' accordingly, can adopt two buttons to be pressed into respectively in two grooves, also can on button, design two as shown in Figure 7 with groove 16/16 ' the projection 20 that is complementary of shape size, be used for the core of lead is compressed, electrically connect reliably realizing.

Because

guide groove

31 and 32 is isolated,

guide groove

33 and 34 is isolated, therefore, when stating the electrically connecting of the bifilar flat cable of realization embodiment illustrated in fig. 6 in the use, except that need make lead enter the part of groove exposed, also need make two strands side by side separate, so that two strands enter guide groove respectively, referring to shown in Figure 8.

For simplifying working process, but the design of slight modification hole and corresponding guide groove is designed to conductor jointer of the present utility model embodiment illustrated in fig. 9, can be directly applied for the connection of bifilar flat cable.The main distinction embodiment illustrated in fig. 9 and embodiment illustrated in fig. 6 is: the shape that is positioned at the hole on outer surface A and the A ' is different from the shape of Fig. 6 mesopore, and simultaneously, the

guide groove

35 and 36 corresponding with hole 30 also distinguished to some extent with the shape of guide groove shown in Figure 8.As seen from Figure 8, be isolated from each other between corresponding with hole 21 and hole 22 two

guide grooves

31 and 32, and as can be seen, communicate between corresponding with hole 30 two

guide grooves

35 and 36 by Figure 10 and Figure 11.Therefore, conductor jointer 12 shown in Figure 9 more is applicable to electrically connecting between the bifilar flat cable.

When conductor jointer of the present utility model is applied to electric cap or electric detonator networking, can prolong signal bus, networking main line, branch line or detonator payment to a porter in the networking convenient, reliably, and can be according to concrete application demand, further design based on technical solutions of the utility model, make it more suitable.

In addition, in the respective embodiments described above, be example with embodiment illustrated in fig. 1, corresponding with groove 16 two

holes

14 and 15 lay respectively at perpendicular on axial two the outer surface A and A ' of groove 16.In fact, these two

holes

14 and 15 also can be positioned on the same outer surface.Adopt implementation like this, the core of lead 3 and lead 4 extends to the groove 16 from the same side of cavity 10, under the effect of pushing of button 2, can realize electrically connecting between lead equally.Further, by changing the size of hole and guide groove, just can control the radical of the lead that passes same hole, therefore, above-mentioned lead 3 and lead 4 also can enter groove via same hole, and formation electrically connects.

Performance when under wet environment, using for improving the utility model conductor jointer, also can be before conductor jointer that lead is packed into, in cavity 10, inject and be similar to the colloidal materials of epoxy resin, the oiliness insulating material that is similar to transformer oil or other thick insulating material, make when being pressed into button 2 in the cavity 10, the thick insulating material that is arranged in cavity 10 is squeezed into guide groove, thereby make the lead core in the cavity 10 be isolated from the outside, and then the influence of extraneous wet environment, the reliability that helps electrically connecting have been avoided.

For making electrically connecting of conductor jointer formation of the present utility model more reliable, also can all be designed to back taper with button 2 and with cavity 43 that the inwall of button 2 contacted cavitys 10 forms, and make the tapering of button 2 be slightly larger than the tapering of above-mentioned cavity 43, this just can be so that button 2 be pressed into tightlyer, thereby button 2 more difficult ejections from above-mentioned cavity 43, this has just further improved the reliability that electrically connects.Here said tapering, i.e. said pattern draft in the machine casting industry.

In addition, also can on button 2, design stuck point 40, for example shown in Figure 13, designing the draw-in groove 41 that on number, shape, size and location, all is complementary with above-mentioned stuck point 40 on the inwall of cavity 10 simultaneously, thereby, after pressing button 2 entered in the cavity 10, stuck point 40 embedded in the draw-in groove 41 corresponding with it, with draw-in groove 41 chuckings.This also can improve the reliability that electrically connects.Similarly, also can be on button 2 with draw-in groove 41 designs, on cavity 10 inwalls, technique effect is identical with corresponding stuck point 40 designs.

In addition, design hangnail 42 also can play similar effect on the inwall of button 2 or cavity 10, and is for example shown in Figure 12.Thereby after button 2 enters in the cavity 10, button 2 will tighten reliably with cavity 10, thereby electrically connect more reliable.

Above-mentioned back taper scheme, stuck point 40 and draw-in groove 41 be used and the design of hangnail 42 can avoid external force do time spent button 2 occur loosening, thereby make conductor jointer of the present utility model to realize better electrically connecting.
