Abstract

The utility model discloses an HDMI connector plug with an improved terminal structure, which comprises an A type HDMI male plug and a conductive terminal, the bottom parts of an upper row of grooves and a lower row of grooves of an isolated plastic seat at the rear part of the male plug are spliced with a plane bonding pad of a welded part at the front end of the conductive terminal, two sides of the bonding pad are provided with welded fins integrated therewith, and the bonding pad and the two welded fins constitute a U-shaped groove. A cable is more easily fixed and welded through the U-shaped groove constituted by the bonding pad and the two welded fins of the welded part at the front end of the conductive terminal, the welding contact area is large, thereby avoiding poor electric conduction, at the same time, the phenomena of tack weld and open circuit resulted from overflow of soldering tin can be avoided.

Description

The HDMI connector plug of improved terminal structure

Technical field

The utility model relates to the syndeton of the signal terminal and the cable of HDMI connector, especially easily the HDMI connector plug of a kind of improved terminal structure of welding.

Background technology

When the PIN pin (conducting terminal) of existing HDMI A type male and cable and neat corresponding welding, because the pad of existing signal terminal is the plane, and the cable rounded naked twisted wire that is cross section; Cable is contacting of line and face with contacting of pad before welding, and promptly contact area is very little; During welding, because pad is the plane, line is convex shape on pad, is difficult for welding, and the as easy as rolling off a log slime flux of scolding tin and cause dry joint and open circuit phenomenon.

The utility model content

Protrude from the problem that contact-making surface that terminal forms is difficult for welding, easily causing dry joint and open circuit for solving above-mentioned cable, the utility model is intended to propose a kind of HDMI connector plug of improved terminal structure.

The technical scheme in the invention for solving the above technical problem is: the HDMI connector plug of improved terminal structure, the A type male and the conducting terminal that contain HDMI, it is characterized in that: the bottom of the two rows groove of the isolation plastic cement seat at male rear portion and the planar pad of conducting terminal front end weld part plug together, the pad both sides are provided with the weldering wing integrated with it, and the pad and the two weldering wings are formed a U type groove.

The U type slot cross-section that is made of the pad and the weldering wing in the utility model is down isosceles trapezoid, conducting terminal front end weld part is used to inlay cable by the U type groove that the pad and the two weldering wings constitute, the line that cable and the formation of U type groove are three touches, make the easier welding of cable and conducting terminal, improve packaging efficiency, weld more reliably, also can prevent that scolding tin is excessive, avoid removing the trouble that secondary processes such as scolding tin are brought.

The beneficial effects of the utility model are: the U type groove that conducting terminal front end weld part is made of the pad and the two weldering wings makes the easier fixing and welding of cable, and the welding contact area is avoided poor flow greatly, and the while can be avoided the scolding tin slime flux and cause dry joint and open circuit phenomenon.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

HDMI connector plug as a kind of improved terminal structure of Fig. 1～shown in Figure 5, in the A type male 1 of HDMI conducting terminal is installed, have the groove of isolate conductive terminal weld part 2 on the male 1 back-connected isolation plastic cement seat 3, the bottom portion of groove on the isolation plastic cement seat 3 and the planar pad 2.1 of conducting terminal front end weld part 2 plug together, pad 2.1 both sides are provided with the weldering wing 2.2 integrated with it, and the pad 2.1 and the two weldering wings 2.2 are formed a U type groove 2.3.Shown in (a) step of Fig. 6, U type groove 2.3 cross sections that the pad 2.1 and the weldering wing 2.2 constitute are down isosceles trapezoid; The weldering wing 2.2 bottoms and pad 2.1 bottom cohesive positions are chamfering, and (b) in the step, U type groove 2.3 is inlayed and fixed cable 4, make the pad 2.1 of cable 4 and U type groove 2.3 contact with the line that the weldering wing 2.2 forms three; (c) in the step, use cable 4 connecting portions in 5 pairs of conducting terminal front ends of scolding tin U type groove 2.3 to weld, mobile scolding tin 5 is filled the gap of 4 of pads 2.1, the weldering wing 2.2 and cables, make the cable 4 and the bonding area of conducting terminal increase, electric conductivity is good, avoid scolding tin 5 slime fluxs simultaneously and cause dry joint and the open circuit phenomenon.

Above embodiment is only for the usefulness that the utility model is described; but not to restriction of the present utility model; those skilled in the art; under the situation that does not break away from spirit of the present utility model and scope; the technical scheme of having done various equivalents or variation should belong to protection category of the present utility model, is limited by every claim.

Claims

1. the HDMI connector plug of improved terminal structure, the A type male and the conducting terminal that contain HDMI, it is characterized in that: the bottom of the two rows groove of the isolation plastic cement seat at male rear portion and the planar pad of conducting terminal front end weld part plug together, the pad both sides are provided with the weldering wing integrated with it, and the pad and the two weldering wings are formed a U type groove.

2. the HDMI connector plug of improved terminal structure as claimed in claim 1 is characterised in that: be down isosceles trapezoid by pad and the U type slot cross-section that the weldering wing constitutes.
