Description

Wire and cable connector and with the method for attachment of cable

The present invention about a kind of wire and cable connector and and the method for attachment of cable, refer to especially a kind of winding cable ends with the wire and cable connector that connects the conducting distinct electronic apparatuses and with the method for attachment of cable.

Wire and cable connector is combined with conducting terminal in the electric connector by some leads usually reaches electrical transmission, usually lead and conducting terminal are combined with dual mode, the one, lead combines by welding manner with conducting terminal, be a kind of existing wire and cable connector 90 behind the dismounting lid as shown in Figure 1, conducting terminal one end extends outside the insulating body, and the end of some leads 91 is removed insulating barrier, and expose core, by the welding between conducting terminal and the core, thereby reach electrical transmission between conducting terminal and cable.Yet, in welding process, for making firm welding, densification, reaching evenly continuously, generally on the industry use that to be made into tin solder by the tin of 63% tin and 37% plumbous or 60% and 40% lead golden as fusing, because lead is toxic metals, in carrying, storage and welding process, can produce injurious effects, obviously run counter to the development trend of current industry " people-oriented " health.

Lead is to be connected with the insulative pricking of lead by conducting terminal to form electrically contact with the another kind of mode of conducting terminal combination.Relevant prior art can be consulted United States Patent (USP) the 4th, 902, No. 242, as shown in Figure 2, electric connector 100 includes insulating body 101 and from the extended plurality of conductive terminals 102 of insulating body 101 bendings, these conducting terminal 102 extending ends are " V " shape, and the insulating barrier 104 of column wire 103 peripheries punctures to incite somebody to action also, and contact with its inner core 105 parts, to reach electrical transmission.Yet, the contact of insulative pricking type is owing to be that plurality of conductive terminals punctures with the plurality of parallel lead is corresponding one by one, this mode has very high requirement to the correspondence position between conducting terminal and the lead, if one of these conducting terminals or lead have deviation slightly, then whole corresponding pass is dislocation therefore, and electrically transmission of influence.Moreover, in the process of puncturing, also might be because of the inequality of pierce force, make between part lead and the conducting terminal loose contact or can't conducting.

The object of the present invention is to provide the wire and cable connector that a kind of electric conductivity is good, easy to assembly fast, fixing is tight and need not to weld.

Another object of the present invention is to provide a kind of simple structure, the quick and good cable method of attachment of electric conductivity easy to assembly.

The object of the present invention is achieved like this: wire and cable connector includes members such as insulator, holding unit, conducting terminal and cable, wherein insulator has front surface and rear surface, be provided with the plurality of terminals accepting groove between its forward and backward surface, accommodate in the accepting groove and fixing has the conducting terminal of respective number, these conducting terminals are provided with the aciculiform portion of protruding the insulator rear surface, and it is terminal tiny and be cone-shaped contraction; Cable includes some leads, and these lead outsides are insulating barrier, the core of leading material for electricity in the insulating barrier; Holding unit abuts against the place, rear surface of insulator, and it is provided with some holding hole that run through holding unit, and these holding hole are the wedged hole configuration that the both ends open diameter does not wait.

Near the lead of cable inserted and extends to the other end of holding hole from the less end of the holding hole diameter of holding unit, in the lead of terminal needle-like portion from the bigger other end insertion holding hole of this holding hole diameter, this needle-like portion is contacted with the core of lead, and the diameter that supports big lead simultaneously makes lead and fixing hole wall produce interference fit and strong fix.

Advantage of the present invention is, terminal aciculiform portion directly is inserted in the core of lead, and is fixed by the wedge shape holding hole of holding unit, thus reach easy to assembly fast, fixing closely and the effect that need not to weld.

The present invention is further illustrated below by accompanying drawing and preferred embodiment.
