Abstract
The invention belongs to the technical field of electric connectors and specifically relates to a high temperature resistant compression-type electric connector voids plugging method. According to the method, a high temperature resistant light-duty lead is selected, the specification of the lead with a double-diameter wire core matching a contact thermocouple is selected, appropriate length of the lead is cut out, wires at two ends are stripped, the lead is folded in half and compressed on the contact thermocouple, and finally the lead is sent into a void cavity. By the adoption of the compression-type electric connector voids plugging method, the requirement of high-temperature work environment at 400 DEG C is satisfied, and the bottleneck problem of a compression-type connector voids plugging technique of a product in a high-temperature work environment is solved.
Description
Technical field
The invention belongs to technical field of electric connectors, be specifically related to a kind of method for blocking of high temperature resistant crimp type electric connector ignore.
Background technology
In connector installation process, there will be some unnecessary need not or standby position, hole, i.e. ignore.If it is bad that these ignores are processed, can directly affect environmental resistance and the electrical property of product integral body.The correct processing method of general provision has two kinds:
Method one: contact and the plug plugging method of obturaging, that is: corresponding contact (not line ball) is sent into position, hole, guarantee that contact puts in place, the plug of obturaging of dimension is inserted in grommet (greatly upside down).The general matching used plug of obturaging is for polyketone sulfide material, and working temperature is 220 ℃, cannot meet the job requirement of 400 ℃ of products and even higher temperature.
Method two: contact line ball plugging method, that is: on corresponding contact, in crimping, after the wire of certain length adaptation, send into position, ignore hole, require the core exposing will carry out insulation processing.The reference method providing according to connector working specification, on contact, the long wire of crimping 10cm, then sends in position, ignore hole.But in practical operation, when ignore is more, the conducting wire end insulation processing of crimping on ignore difficulty, wire easily overlaps each other, or itself and with the screen overlap joint of shielded conductor in bunch of cables, cause short circuit or ignore and the short circuit problem shielding between ground between ignore.In actual use, after cable and equipment interconnection, if some position is used on the equipment connector corresponding with cable-to-cable connector ignore, can cause airborne equipment operation irregularity, airborne equipment is burnt in serious meeting, has certain risk.Under hot environment, cable-to-cable connector ignore method for blocking needs to break through.
Summary of the invention
The present invention is optimized the even line ball plugging method of the contact in said method two, by crimping after compression bonded line doubling, thereby solved cleverly in method two the wire unmanageable problem of end that suspends, compression bonded line is selected high temperature resistant light gauge wire, can be good at meeting the requirement of high-temperature work environment.Conductor length is to contact after even being in place, and wire peak protrudes electric connector sealing body surface 2mm～4mm and is as the criterion, and has facilitated and while reprocessing, has contacted even dismounting.
Concrete technical scheme is as follows
Adopt the high temperature resistant light gauge wire that can meet ambient temperature requirement flexible, insulating barrier is thinner, select its double core and contact the even specification matching, intercept suitable length, two wire stripping, after doubling, in crimping, contact is even, then sends in ignore vestibule.
Beneficial effect
The crimp type connector ignore method for blocking that the present invention adopts, meets 400 ℃ of operational environment requirements of high temperature, has solved the bottleneck problem of crimp type connector ignore blocking technological method under product high-temperature work environment.
Accompanying drawing explanation
Fig. 1 is high temperature resistant crimp type electric connector ignore contact crimping lead wire schematic diagram;
1-wire; 2-contact
Embodiment
Now the embodiment of achievement is further described:
1) select wire type.While selecting wire, need to consider three aspects: content,
The one, pliability is better;
In the identical situation of Er Shi wire core diameter, select the thinner light gauge wire of insulating barrier;
The 3rd, its material of requirement can meet ambient temperature requirement.
In conjunction with the design objective of current a plurality of supersonic speeds, hypersonic type of missile, at this, recommend the high temperature resistant light gauge wire of a kind of FY4Q-2 type.
2) wire gauge is selected.Under the double wire diameter that the meets wire core precondition adaptive with contacting idol, wire is as far as possible thin.
According to current application, contacting more widely even model recommends:
22D contacts even 7 * 0.14 wires that select with 20#;
Even 19 * 0.16 wires that select of 16# contact.
3) conductor length is determined.
When determining conductor length, need defer to following principle:
1., after being in place, the length that conducting wire end stretches out electric connector sealing body should facilitate secondary dismounting;
2., after being in place, not affecting electric connector tail and clamp and join.
Length of recommended is: line ball contact is even send into ignore and put in place after, wire protrudes sealing body surface 2mm～4mm.
4) wire stripping head.
Requirement is after compression bonded line doubling, two ends wire stripping, long measure (mm)
Crimping 22D contacts even wire wire stripping length: 4+0.38;
Crimping 20# contacts even wire wire stripping length: 4.9+0.7;
Crimping 16# contacts even wire wire stripping length: 5.4+0.7.
5) contact crimping even and wire.
By strip head heart yearn two ends together with contact even crimping.
7 * 0.14 wires contact even crimping and use M22520/2-01 type Press Plier with 22D, crimping gear is 2 grades;
7 * 0.14 wires contact even crimping and use M22520/1-01 type Press Plier with 20#, crimping gear is 1 grade;
19 * 0.16 wires contact even crimping and use M22520/1-01 type Press Plier with 16#, crimping gear is 4 grades;
6) contact that presses line is occasionally sent in corresponding ignore vestibule, guaranteed to deliver to position.
