Abstract
The utility model relates to a heat shrinking special-shaped piece for an electric connector, which is a tubular heat shrinking special-shaped piece with a large caliber and one or more small calibers. The ring periphery of an inner hole is provided with hot-melt adhesive; the end of the large caliber of the special-shaped piece after heat shrinking is spliced with a tail part of the electric connector, and the ends of the small calibers are spliced with cable wire bunches; thus, the performances of mechanical protection, sealing property, anticorrosion, stress relief, etc. of the connection between the electric connector and cable wires can be enhanced effectively, and the electric connector can be used in the adverse environment of acid, alkali, salt fog, etc. to ensure the quality of military industry matching products.
Description
Affiliated technical field
The utility model relates to a kind of electric connector, is particularly useful for the protective device of mechanical protection, sealing, anticorrosion and stress relieving etc. that electric connector is connected with core of a cable.
Background technology
Existing electric connector electric wire or cable in use is connected with plug or socket respectively.Need have performances such as waterproof, anticorrosion, connection be firm as military electric connector.At present, electric connector in use normally puts rubber sleeve in the junction of electric connector and core of a cable.This mode sealing effectiveness is very poor, often water inlet, and cable stress can not be removed in addition, causes the core of a cable broken string, goes offline, and directly influences the service behaviour and the military products quality of electric connector.
Summary of the invention
In order to overcome the shortcoming that prior art exists; the purpose of this utility model provides a kind of protective device of electric connector; and provide a kind of electric connector that adopts this protective device; thereby avoid the water inlet that in use occurs, the phenomenon that goes offline, breaks, improve the reliability and the service behaviour of electric connector.
The utility model is to realize like this, it is a tubulose thermal contraction profiled piece, and a heavy caliber and one or more small-bore is arranged, and interior orifice ring week scribbles PUR, profiled piece heavy caliber end and electric connector afterbody after heat shrink is bonding, and small-caliber end and core of a cable are bonding.
The thermal contraction profiled piece comprises special-shaped straight tube or special bent pipe or special-shaped many vials, and profiled piece big small-bore transition position after heat shrink is funnel-form or circular-arc.Shrinkage ratio before and after the heating of thermal contraction profiled piece is (2.5-10): 1.
Adopt the electric connector of above-mentioned thermal contraction profiled piece, it comprises electrical connector body and the core of a cable that is connected with body, electrical connector body afterbody and core of a cable junction are with tubulose thermal contraction profiled piece, this profiled piece comprises small-bore greatly, heavy caliber one end is enclosed within on the electric connector afterbody, small-bore being enclosed within on the core of a cable makes itself and electric connector afterbody, core of a cable closely bond after heat shrink.
Adopt the utility model; the thermal contraction profiled piece is sleeved on the cable; small-caliber end parcel core of a cable; heavy caliber end parcel electric connector afterbody; after heating; make it and the electric connector afterbody; core of a cable closely bonds; PUR has been filled the atomic little slit of junction; make electric connector become the integral body of a real meaning with cable; thereby improved the mechanical protection that electric connector is connected with cable effectively; sealing; anticorrosion; separate performances such as de-stress; make the electric connector can be in acid; alkali; use under the adverse circumstances such as salt fog, improved the reliability of electric connector greatly, guaranteed the quality of military project auxiliary products.

In shown in Fig. 1,2,3,4, electrical connector plug 1, core of a cable 2, thermal contraction profiled piece 3.
Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
The thermal contraction profiled piece of the electric connector as shown in Figure 1, 2 is a straight tube, bore is that a heavy caliber and one are small-bore, inside pipe wall ring week scribbles PUR, special-shaped straight tube is after heat shrink, large and small bore transition position is funnel-form or circular-arc, heavy caliber end and electric connector afterbody are bonding, and small-caliber end and core of a cable are bonding.
As shown in Figure 3, the thermal contraction profiled piece is a special bent pipe, bore is that a heavy caliber and one are small-bore, inside pipe wall ring week scribbles PUR, special bent pipe is after heat shrink, and big small-bore transition position is 90-120 ° of bending, and transition position is funnel-form or circular-arc, heavy caliber end and electric connector afterbody are bonding, and small-caliber end and core of a cable are bonding.
As shown in Figure 4, the thermal contraction profiled piece is special-shaped many vials, bore is a heavy caliber and a plurality of small-bore, inside pipe wall ring week scribbles PUR, special-shaped many vials are after heat shrink, large and small bore transition position is funnel-form or circular-arc, and heavy caliber end and electric connector afterbody are bonding, and a plurality of small-caliber ends and multiply branch cable wire harness are bonding respectively.
During use; the core of a cable that the electric connector afterbody is connected passes the thermal contraction profiled piece; and with thermal contraction profiled piece heavy caliber end towards electric connector; and profiled piece heavy caliber end is enclosed within on the electric connector afterbody, then to its heating, make its contraction; the PUR melt-flow of while inside pipe wall; fill atomic little slit, junction, thermal contraction profiled piece and electric connector afterbody and core of a cable are closely bonded, adopt this protective device effectively to improve the reliability and the service behaviour of electric connector.
This thermal contraction profiled piece is widely used in mechanical protection, sealing, anticorrosion and the stress relieving etc. of the continuing of various electric connectors in the industry system equipments such as space flight, aviation, weapons, electronics, communication, machinery, boats and ships, medical treatment, railway, oil, branch part.
