Abstract

A cable connector is used for a portable electrical device to transmit data or power, including a patching plug, an inner circuit board connecting with the patching plug, and an insulation outer housing, which covers the patching plug, and inner circuit board. The patching plug includes many conducting terminals with welded parts, and the inner circuit board is equipped with many welded feet; the welded parts are welded on welded feet corresponding to the inner circuit board, and the welded position between the welded part of the conducing terminals and the welded feet of the inner circuit board is equipped with a plastic body which fixes the patching plug and inner circuit board together. Therefore, the joint between the conducting terminals and welded feet of the circuit board is not affected by the external forces, ensuring the reliable electrical connection between the patching plug and the inner circuit board.

Description

Wire and cable connector

[technical field]

The utility model relates to a kind of wire and cable connector, refers in particular to a kind of being applied on the portable electron device in order to transmit the wire and cable connector of data or power supply.

[background technology]

The prior art relevant with the utility model can be consulted the United States Patent (USP) the 6th of bulletin on April 3 calendar year 2001,210,229B1 number, the wire and cable connector that this patent disclosed comprise match on, following insulation crust and being contained on this, connection-peg and internal circuit board in the following insulation crust, wherein connection-peg comprises plurality of conductive terminals, described conducting terminal directly welds mutually with the internal circuit board conductive path, the defective of this design is: this connection-peg and this internal circuit board are assembled in, in the process in the following insulation crust, the pad of conducting terminal and internal circuit board is subject to the external force influence and causes scolding tin to come off, thereby can't realize the function of signal or power delivery.

[utility model content]

The utility model purpose is to provide a kind of wire and cable connector that connection-peg and internal circuit board reliably can be connected.

The purpose of this utility model is achieved through the following technical solutions: described wire and cable connector is applied on the portable electron device in order to transmission data or power supply, comprise connection-peg, internal circuit board that electrically connects with connection-peg and the insulation crust that coats this connection-peg and internal circuit board, wherein connection-peg comprises the plurality of conductive terminals with weld part, internal circuit board is provided with some welding foots, described weld part is welded on the welding foot of internal circuit board correspondence, and is provided with the plastic body that connection-peg and internal circuit board are fixed together outside described conducting terminal weld part and the position that the internal circuit board welding foot welds mutually.

Compared with prior art, the utility model connection-peg conducting terminal and internal circuit board welding foot mutually the peripheral integral body of welding assembly one plastic body is set to form forming module, thereby needn't directly force in the welding foot of connection-peg and internal circuit board in the installation process, guarantee to electrically connect reliably between connection-peg and the internal circuit board.

[embodiment]

Please refer to Fig. 1 to shown in Figure 3, the utility model wire and cable connector 500 described wire and cable connectors are applied on the portable electron device to comprise connection-peg 1, internal circuit board 2, plastic body 3 and insulation crust 4 in order to transmission data or power supply.

Connection-peg 1 comprises insulating body 11, be contained in the conducting terminal 13 in the insulating body 11 and the metal shell 12 of coated insulation body 11.Insulating body 11 is roughly stepped, comprise base portion 111 and the extension 110 that extends by base portion 111, extension 110 is provided with the accepting groove 114 of accommodating connector (not shown), base portion 111 is provided with the slit 113 that back space 112 and upper and lower two rows are communicated with 112 of accepting grooves 114 and back spaces, and the upper and lower surface of base portion 111 convexes with some clamping parts 115 respectively.Each conducting terminal 13 number of comprising shape weld part 131, with weld part 131 to the arc-shaped contact part 133 of same direction bending be connected the holding parts 132 of this weld part 131 and contact site 133, the holding parts 132 of each conducting terminal 13 is immobilizated in the slit 113 of insulating body 11, and weld part 131 extends to respectively in back space 112 and the slit 113 with contact site 133.Described metal shell 12 comprises the root 120 of extension 110 outer surfaces that are coated on insulating body 11 and some retaining sheets 121 of extending back of this root 120 certainly, the centre of each retaining sheet 121 is provided with the square holding hole 122 that the clamping part 115 with insulating body 11 fastens, thereby metal shell 12 is retained on the insulating body 11.

Internal circuit board 2 is provided with conductive path (not shown) and some and conducting terminal 13 weld parts 131 and the terminal welding foot (not label) that electrically connects of cable (not label).One end of internal circuit board 2 is inserted in the back space 112 of connection-peg 1, and be held between the weld part 131 of upper and lower two row's conducting terminals 13, weld part 131 is welded on the welding foot of internal circuit board 2 correspondences, and cable is welded on the corresponding welding foot of internal circuit board 2 relative another sides.

Plastic body 3 is for global formation and be coated on outside connection-peg 1 and the position that internal circuit board 2 welds mutually with formation a molding piece 5, for making cable firmly be connected with internal circuit board 2, in the present embodiment, cable ends also is wrapped in the plastic body 3 with the position that internal circuit board 2 welds mutually.

Insulation crust 4 is global formation and is coated on outside the above-mentioned forming module 5 that this insulation crust 4 comprises the main part 41 of Overmolded module 5 and the cable holding parts 42 that is extended by middle part, main part 41 rear ends.Wherein the front end of main part 41 is provided with the opening 411 that makes connection-peg 1 front end extend this insulation crust 4, and the upper and lower surface of main part 41 respectively is provided with circular handle part 412, and main part 41 upper and lower surfaces respectively offer at least one air-vent 413 in order to heat radiation.
