Abstract
The utility model provides a testing tool for embedment of a wiring harness terminal and a joint plug-in piece. The testing tool comprises a slide block body, a trigger switch and a counter, wherein one side face of the slide block body indents inward to form a U-shaped sliding chute, two side portions of the U-shaped sliding chute are provided with a plurality of grooves corresponding to the upper surface and the lower surface of the joint plug-in piece, the trigger switch arranged on one side portion of the U-shaped sliding chute is close to one end of the bottom of the U-shaped sliding chute and is connected with the counter, and the distance between the two side portions of the U-shaped sliding chute is equal to the thickness between the upper surface and the lower surface of the joint plug-in piece. The testing tool can detect whether the terminal is completely plugged in the joint plug-in piece so as to prevent rejects caused by falling of a half plugged terminal from being produced.
Description
[technical field]
The utility model relates to a kind of Wiring harness terminal and the chimeric testing tool of connection plug-in unit.
[background technology]
At present, no matter be senior luxury car or economical general-utility car, the form that wire harness is weaved into is the same basically, all is comprised of electric wire, connection plug-in unit and parcel adhesive tape.
Automobile electric wire claims again low tension wire, and it and normal domestic use electric wire are different.The normal domestic use electric wire is copper single stamen electric wire, and certain degree of hardness is arranged.And automobile electric wire all is copper many stamens flexible cord, and some flexible cord is thin such as hair, and several and even tens annealed copper wires are wrapped in the plastic insulating tube (Polyvinylchloride), softness and be not easy to fracture.
Wire harness is with woven line or plastics adhesive tape parcel, and for safety, processing and easy to maintenance, woven line parcel is eliminated, and is with viscous plastic adhesive tape parcel now.Being connected between wire harness and the wire harness, between wire harness and the electricity piece, adopt connection plug-in unit or line ear.The connection plug-in unit is made of plastic, and dividing has plug and socket.Join being connected with connection plug-in unit or line ear between wire harness and the electricity piece between wire harness and the wire harness with the connection plug-in unit.
The connection plug-in unit is a kind of part on the wire harness, usually has plastics to make, and in the wire insertion phase with pressure side, guarantees the reliability that connects.
As shown in Figure 1; one side of connection plug-in unit 20 inserted terminals is provided with an end cap 201; when assembly process; terminal is inserted in the supporting connection plug-in unit 20; often can assemble phenomenon not in place and occur, the end cap 201 that namely joins a side of plug-in unit 20 inserted terminals can upwards swell, and namely terminal is for inserting the tram; can cause terminal to come off, produce defective products.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of Wiring harness terminal and connection plug-in unit chimeric testing tool, can detect terminal and whether insert the connection plug-in unit fully, prevents that half terminal that inserts from coming off and produce defective products.
The utility model is achieved in that
A kind of Wiring harness terminal and the chimeric testing tool of connection plug-in unit, described testing tool comprises a slide block body, a trigger switch and a counter, described slide block body one side caves inward and forms a U-shaped chute, the both sides of described U-shaped chute are provided with the plural groove corresponding with joining the plug-in unit above and below, described trigger switch is arranged on the sidepiece of U-shaped chute, and a bottom one end of close U-shaped chute, described trigger switch links to each other with described counter; Distance between the both sides of described U-shaped chute equates with the thickness that joins between the upper and lower change face of plug-in unit.
Further, described U-shaped chute just holds whole plug-in unit.
The utility model has the advantage of:
Distance between the both sides of the described U-shaped chute on the slide block body equates with the thickness that joins between the upper and lower surface of plug-in unit, when terminal half inserts the connection plug-in unit, one end cap of one side of connection plug-in unit inserted terminals can upwards swell, this end cap is the upper surface that is positioned at the connection plug-in unit, the thickness that join between the upper and lower surface of plug-in unit this moment will be greater than the distance between the both sides of U-shaped chute, namely join plug-in unit and can't pass through U-shaped chute, and then can't run into trigger switch, counter just without showing, shows that the terminal of this connection plug-in unit is not inserted into the tram; Therefore, the utility model can detect terminal and whether insert the connection plug-in unit fully, prevents that half terminal that inserts from coming off and produce defective products; In addition, the both sides of U-shaped chute are provided with the plural groove corresponding with joining the plug-in unit above and below, and qualified connection plug-in unit is passed through more smoothly.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the existing structural representation of plugging the connection plug-in unit of terminal.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the schematic diagram that the utility model cooperates with the connection plug-in unit.
[embodiment]
See also shown in Fig. 2 ~ 3, embodiment of the present utility model is described in detail.
As shown in Figures 2 and 3, a kind of Wiring harness terminal and the chimeric testing tool of connection plug-in unit that the utility model is related, described testing tool comprises a slide block body 1, a trigger switch 2 and a counter 3, described slide block body one side caves inward and forms a U-shaped chute 4, the both sides 41 of described U-shaped chute 4 are provided with the plural groove 42 corresponding with joining plug-in unit 20 upper surfaces 202, lower surface 203, the sidepiece 41 that 2 passes are arranged on U-shaped chute 4 is opened in described triggering, and a bottom 43 1 ends of close U-shaped chute 4, described trigger switch 2 links to each other with described counter 3; The thickness D that the distance L that the both sides of described U-shaped chute 4 are 41 and connection plug-in unit 20 upper surfaces 202, lower surface are 203 equates; Described U-shaped chute 4 just holds whole plug-in unit 20, and described testing tool is fixed on the fixed head 10.
Principle of operation of the present utility model is as follows:
Emphasis is consulted Fig. 3, the side that is plugged the connection plug-in unit 20 of terminal is slipped into from the opening of U-shaped chute 4 one sides of slide block body 1, opening from opposite side skids off again, connection is inserted 20 and is touched the trigger switch 2 that is arranged on U-shaped chute 4 sidepieces 41 in the process of sliding, with just show one several 1 on the counter 3 that trigger switch 2 links to each other, the end cap 201 that this connection plug-in unit 20 is described does not swell, and the terminal insertion position of connection plug-in unit 20 is correct; If show that numerical value is 0 on the number device, show that then the terminal of this connection plug-in unit 20 is not inserted into the tram.
