Description

Electrical adapter

The utility model relates to the electric connector field, relates in particular to the electrical cnnector of a kind of Pierre's of being applied to computer and surrounding devices thereof.At present the electrical cnnector that uses as shown in Figure 1, 2, connector 1 is by

shell body

10,11 up and down,

inner housing

12,13, jack base 14 constitutes with cable 15.Wherein be provided with a plurality of jacks 141 in the jack base 14, each jack 141 is equipped with conducting strip 1411, each conducting strip 1411 suitable length that all stretches out; Be surrounded by strand wire 151 in the cable 5, each electric wire 151 of cable 15 welds mutually with the conducting strip 1411 of jack 141 respectively, and

inner housing

12,13 is fastened on the rear end of jack base 14, and the upper and

lower casing

10,11 that periphery forms with the plastic cement mold pressing again covers mutually and closes.In above-mentioned structure, jack base 14 engages with cable 15, need remove the conducting strip 1411 of each jack 141 on the pin jack seat 14 with artificial each electric wire 151 of clamping one by one, in addition spot welding forms contact 1412 again, as shown in Figure 3, each contact 1412 periphery also need be coated with insulating cement 16, in case two

inner housings

12,13 are when being fastened on jack base 14 front ends, contact 1412 is subjected to the inboard extruding of inner housing and is in contact with one another the formation short circuit; And in manufacture process, need artificial clamping electric wire 151 one by one to remove the conducting strip 1411 of each jack 141 on the pin jack seat 14, spot welding in addition again, such operation utmost point labor intensive, also be easy to generate failure welding, the substandard products of service interruption, the operation quality that each contact 1412 periphery is coated with insulating varnish also is difficult for stablizing, thereby is difficult to reduce cost.

The purpose of this utility model is to provide a kind of electrical cnnector that is provided with circuit board, and its advantage is that electric wire and connector conducting strip do not need to link one by one by hand and spot welding.Must not be coated with insulating cement in the contact periphery yet, thus simple for production, and available automatic welding reduces cost; And quality improves, and is not prone to short circuit.

The utility model is achieved in that and electricly includes a jack base, a cable, a shell, two inner housings with plug; Wherein the jack base rear portion is provided with a catching groove, its front end is provided with a plurality of jacks, establish a conducting strip in each jack, this conducting strip stretches out a suitable length to the catching groove rear, it is characterized in that: what link cable and jack base is to adopt circuit board, circuit board front end width approximates the inboard width of jack base catching groove, and can fasten mutually, circuit board is provided with a plurality of conducting terminals, each conducting terminal respectively is provided with a jack, when the circuit board front end is fastened in the catching groove of jack base, stretch out outside the catching groove, the a plurality of conducting strips that are the pectination arrangement adapt to the corresponding conducting terminal of being close on the circuit board, and many electric wires of cable are plugged in the corresponding jack on the circuit board one by one respectively, are connected with automatic spot.

The electric many electric wires with the adapter lead line of said structure can enter the jack on the circuit board in proper order, and the conducting terminal of itself and jack base is connected with stitch welding machine spot welding, therefore reduced a large amount of hand labours, and point quality is good, spot pitch is guaranteed, need not to be coated with insulating cement again in its periphery, thereby has simplified technology, improved quality, improve work efficiency, reduced cost.
