Description
Technical field
The present invention relates to the conduction adhering method of a kind of electrical apparatus interstar connection post and wire, the conduction that is specially adapted to the upper binding post of electric equipment (power supply, electronic instruments) and wire is gluedd joint.
Background technology
Electric equipment, electronic product are widely used in the industrial circles such as automobile, electronics, Aeronautics and Astronautics, boats and ships, conventionally need internally access power supply and the externally various control of output and signal data.The general volume of this series products is little, lightweight, inner space is limited, require to have certain seal approach simultaneously, make inside and outside isolation mutually, so be generally to realize inside and outside conduction by binding post short and thin on housing to connect, first inner lead is connected with binding post, seal casinghousing again, when using or test, again binding post is connected with outer lead, generally adopt at present screw threads for fastening method to be connected with tin-lead solder welding both at home and abroad, the shortcoming of these two kinds of methods is: screw threads for fastening method adopts mechanical force to compress binding post and wire, reach both close contacts, but in product use procedure, run into vibration repeatedly, just easily occur loosening, cause loose contact, and easily affected by environment, under humidity or salt fog condition, burn into can occur contact point causes resistance to increase or joint fails occurs, tin-lead solder welding is because the inside and outside two ends of binding post all adopt tin-lead solder welding, after housing seal, in binding post on carrying out housing and outer lead welding process, in the time of the outside solder of flatiron heat fused, the binding post that inside has been welded and the solder joint of inner lead have carried out secondary fusion, and because the general length of binding post is short, diameter is little, reach heat balance time very fast, this secondary fusion effect is fairly obvious, caused the internal welding point deformation of binding post, active component attenuation, rosin joint, inefficacy even comes off, simultaneously because this variation occurs in instrument, can not find, while only having service interruption, just can pinpoint the problems.Although conventionally taked the higher S-Sn40PbA solder of fusing point for interior welds, the lower S-Sn60PbA solder of fusing point for outside weldings, and the method for controlling weld time, all can not stop the infringement that inner solder joint is caused.The fusing point of S-Sn40PbA solder is 183～238 ℃, the fusing point of S-Sn60PbA solder is 183～190 ℃, both are difference to some extent, but initial melting temperature is identical, that is to say that two kinds of solders melt deliquescing simultaneously, and the welding temperature of general soldering is higher 60～80 ℃ than solder fusing point, just can make the complete melting of solder, guarantee quality of welding spot.The method of controlling weld time is also infeasible: each operator feels different to 1～2 second time, and in reality, existence needs the situation of reprocessing after welding.Weld time, the too short outside weldings solder that can affect melted, and caused " hard-core ".After product is sold, user in welding outside lead process, more difficult control weld time, the infringement that inner solder joint is caused is inevitable, thereby has reduced the reliability of product.
Summary of the invention
The technical problem that the present invention solves: the conduction adhering method that a kind of electrical apparatus interstar connection post and wire are provided, can make the not temperature influence that is connected between binding post and wire, prevent binding post internal welding point failure, improve electric equipment conduction quality of connection, thereby improve the unfailing performance of product.
The technical solution used in the present invention: the conduction adhering method of electrical apparatus interstar connection post and wire, comprises following step:
1) the inner lead one end that is placed in housing inner chamber is fixedly connected with inner member, then the inner lead other end is fixedly connected with binding post one end, finally by housing seal;
2) outer lead one end be wrapped in to the binding post other end and tighten, with silk or absorbent cotton, dipping in ethanol or gasoline cleans up the winding position of outer lead and binding post, coated with conductive glue;
3) the position room temperature of coated with conductive glue dried or solidify at a certain temperature.
Above-mentioned steps 2) in, described conductive gelatin consists of the raw material of following weight parts: epoxy resin 1, silver powder 3～4, additive 0.2～0.3, wherein said additive consists of with the white carbon that can increase conductive gelatin intensity the triethanolamine that can increase conductive gelatin mobility, and the weight ratio of triethanolamine and white carbon is 6～8:1.
Above-mentioned steps 2), in, externally during the winding position coated with conductive glue of wire and binding post one end, optionally can be coated with 2～3 times, until gluing position full, do not reveal wire.
Preferably, the inner lead other end and binding post one end brazing.
Preferably, the inner lead other end is also fixedly connected with by coated with conductive glue with binding post one end.
The present invention has compared with prior art solved binding post one end while being connected with outer lead, the deficiency that originally adopts screw threads for fastening method and welding method to exist, improved the reliability of product, there is larger using value, the coating of conductive gelatin is easy to operate simultaneously, conductive gelatin solidifies under room temperature or lower temperature, when realizing binding post and the splicing of outer lead conduction, can not cause the solder joint distortion of inner solder joint, attenuation, rosin joint, even come off, guaranteed the quality of inner solder joint, prevented that in use procedure, problem loosening or corrosion appears in contact point, the hidden danger of quality of having avoided product to exist, improved the unfailing performance of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing 1, a kind of embodiment of the present invention is described.
The conduction adhering method of electrical apparatus interstar connection post and wire, comprises following step:
1) inner lead 3 one end that are placed in housing 5 inner chambers are fixedly connected with inner member 4, then inner lead 3 other ends are fixedly connected with binding post 2 one end, finally by housing 5 sealings; Specifically have two kinds of modes to select: the one, inner lead 3 other ends and binding post 2 one end brazings; The 2nd, inner lead 3 other ends are also fixedly connected with by coated with conductive glue with binding post 2 one end;
2) outer lead 1 one end is wrapped in to binding post 2 other ends and tightens, with silk or absorbent cotton, dip in ethanol or gasoline cleans up the winding position of outer lead 1 and binding post 2, coated with conductive glue, optionally can be coated with 2～3 times, until gluing position full, do not reveal wire, described conductive gelatin consists of the raw material of following weight parts: epoxy resin 1, silver powder 3～4, additive 0.2～0.3, wherein said additive consists of with the white carbon that can increase conductive gelatin intensity the triethanolamine that can increase conductive gelatin mobility, and the weight ratio of triethanolamine and white carbon is 6～8:1, above-mentioned conductive gelatin, its specific insulation is little, adhesive strength is large, ageing-resistant performance is good, be coated in binding post one end that on instrument housing 5, binding post 2(exposes, and on it, cover has glass or plastic insulation 6 and housing 5 insulation) form outside both glue joints 7 with the junction of outer lead 1, reach and both guarantee conductivity and strength of joint, realize again under lower temperature and connecting, reach the object that prevents that binding post 2 one end (being sealed in the one end in housing 5) and internal welding contact 8 meltings of inner lead 3 were lost efficacy, if inner lead 3 all adopts bonding mode to be connected with binding post 2 with outer lead 1, better effects if.
