Abstract

The invention provides a connector terminal weld part forming method and structure. The method comprises the following steps: to began with, preparing a lamellate terminal material strip which is formed with a plurality of terminals which are laterally arranged side by side and each terminal has a welding part, with the lateral margins of the welding parts being pasted in alignment with each other; and then, tearing the terminal material strip along each lateral margin of each welding part such that the wielding part of each terminal is staggerly separated in an up-and-down manner to form welding parts of the terminals for a connector, wherein the lateral margins of the welding parts of any two adjacent terminals are tangent in an aligned manner in a downward-view projection. Under the condition that the occupied area of the terminal material strip is not added, the weld part of the connector terminal is enabled to have larger surface area, so that a core of a cable is welded with the connector more easily.

Description

Weld part forming method and the structure thereof of bonder terminal

Technical field

The present invention is relevant relevant for a kind of electric connector, refers to a kind of weld part forming method and structure thereof of bonder terminal especially.

Background technology

At present, at present I/O connector still need by with being connected of cable, and each core of cable must weld supervisor with corresponding terminal, the transmission of adding connector now is complicated and make that its number of terminals is huge to be increased, and connector on overall volume towards the design of downsizing, so make cable and bonder terminal more difficult in welding.

Especially, the tradition connector only merely with its terminal with after each core of cable is done corresponding arrangement, namely carry out weld job, but do not consider that each terminal and core are all too meticulous and intensive, and make the solder joint may be not with problems such as the two bondings, the fraction defective that causes I/O connector to engage with cable rises, and very the person influences transmission quality.

Summary of the invention

In view of this, main purpose of the present invention is to provide a kind of weld part of bonder terminal that makes can have bigger surface area with easier weld part forming method and structure thereof of carrying out the bonder terminal of weld job.

To achieve the above object, the invention provides a kind of weld part forming method of bonder terminal, its step is as follows:

A) prepare a sheet terminal material belt, be formed with laterally side by side terminal of plural number on this terminal material belt, and these terminals have a weld part respectively, respectively the weld part lateral margin of this terminal pastes together mutually;

B) tear described terminal material belt along the weld part lateral margin of this terminal, and respectively the weld part of this terminal separates and moulding according to upper and lower interlace mode.

To achieve the above object, the present invention also provides a kind of connector, comprising:

One insulating body has the tongue piece that a pedestal and is extended by this pedestal front end; And

Plural terminals is embedded in this pedestal, and has respectively to show in the contact site on this tongue piece and and be exposed to weld part on this pedestal;

Wherein, respectively the weld part of this terminal goes to upper and lower interlace mode and arranges, and the weld part lateral margin of any two adjacent described terminals trims mutually on downward projection.

The present invention is not increasing under the shared area situation of terminal material belt, makes the weld part of bonder terminal can have bigger surface area, so be able to the weld job of the core of cable on easier carrying out, to improve the shortcoming of known technology.

Embodiment

Further understand feature of the present invention and technology contents in order to make, see also following about detailed description of the present invention and accompanying drawing, yet appended accompanying drawing only provide with reference to and the explanation usefulness, the present invention is limited.

The invention provides a kind of weld part forming method and structure thereof of bonder terminal, as the step S1 of Fig. 1 and cooperate shown in Figure 2: at first, prepare a sheet terminal material belt 1, this terminal material belt 1 has a connecting end 10 and is formed at these link 10 1 sides and is horizontal plural terminals 11 side by side, and this terminal 11 has a contact site 110 and a weld part 111 respectively, the weld part 111 of each terminal 11 is wide than its contact site 110, pastes mutually together and not for weld part 111 lateral margins 112 of wantonly two adjacent terminals 11 and separates; And the present invention for embodiment in, the connecting end 10 of this terminal material belt 1 is provided with for the perforation 100 that is positioned board (figure slightly), and the end is intermarginal is connected to constitute with extension 101 with the weld part 111 of some terminals 11.

See also the step S2 of Fig. 1 again and cooperate Fig. 3 to shown in Figure 4: then, with a upper and lower

relative mould

12,13, tear described terminal material belt 1 along weld part 111 lateral margins 112 of each terminal 11, and the weld part 111 of each terminal 11 is separated and moulding according to upper and lower interlace mode; For example, if mold 12 corresponding odd number terminals 11, then bed die 13 is corresponding even number terminal 11, so, when upper and

lower mould

12,13 is laminated, can make the weld part 111 strange, even number terminal 11 on the terminal material belt 1 separate according to upper and lower interlace mode, namely as shown in Figure 5.

To shown in Figure 8, connector of the present invention comprises that an insulating body 2 and plural aforementioned terminal 11 constitute as Fig. 6, and this insulating body 2 has the tongue piece 21 that a pedestal 20 and is extended by pedestal 20 front ends; And the present invention for embodiment in, pedestal 20 is combined by anterior 200 and one rear portion 201, the front portion 200 of pedestal 20 is embedded in it for described terminal 11, and the contact site 110 that makes each terminal 11 extends and shows on tongue piece 21, the weld part 111 of 201 each terminals 11 of confession in the rear portion of pedestal 20 exposes thereon, and on 201 ends of rear portion, two side places are provided with plural groove 202 respectively down, weld part 111 correspondences for each terminal 11 are inserted, anterior 200 rear ends are provided with a patchhole 203 in addition, insert in it, so as to combining a described pedestal 20 for the rear portion 201 front ends projection established 204 of dashing forward.

Hold, for ease of this connector and a cable 4 combinations, one fen line structure 3 can be set between this connector and cable 4; This minute, line structure 3 was provided with respectively the cross-line hole 30 corresponding with each groove 202 at pedestal 20 rear portions 201, core 40 for cable 4 can correctly correspond in each groove 202 at pedestal 20 rear portions 201 by each cross-line hole 30 respectively, pass through again as means such as welding in each groove 202, to form solder joint 41, and the core 40 that makes cable 4 respectively with weld part 111 solder joints, so as to being able to and cable 4 combinations for this connector.

In addition, this connector more can coat a metal shell 210 at its insulating body 2; And the present invention for embodiment in, this metal shell 210 is coated on the peripheral place of tongue piece 210 of insulating body 2, namely as shown in Figure 8.

Be with, by above-mentioned contexture, can obtain weld part forming method and the structure thereof of bonder terminal of the present invention.

Accordingly, as Fig. 5 and shown in Figure 6, owing to going to upper and lower interlace mode, arranges the weld part 111 of each terminal 11, and weld part 111 lateral margins 112 of any two adjacent described terminals 11 trim mutually on downward projection, therefore the present invention can make each terminal 11 strengthen its surface area at weld part 111, and do not influence each terminal 11 shared area on terminal material belt 1, therefore be able to weld with each core 40 cable 4 easilier, reduce the generation of problems such as failure welding.

But the above only is preferable possible embodiments of the present invention, is not so namely limits to claim of the present invention, so variations such as the equivalence techniques that every utilization specification of the present invention and accompanying drawing content are done, means all in like manner are contained in the scope of the present invention.
