Abstract

The utility model discloses a micro USB connector plug. A casing is in socket joint and fixed with a plug-in plate at the front part of a base, an electric touch terminal set is plugged in the base, and the tail end of each terminal is plugged into and exposed; a grab is arranged on each side of the base, and the tail part of the grab is plugged into the rear plug; two raised sticking points are arranged on the clamping part of each terminal, and a weld surface perpendicular to the side surface of the terminal is arranged at the tail part of the terminal. Through the two sticking points designed at the clamping part of the electric touch terminal, the terminal is in interference fit with the plug hole on the base, and the two sticking points and the plug hole can form a barb to stop the backward movement of the terminal. Meanwhile, the right-angle weld surface capable of increasing welding surface is arranged at the tail part of each terminal, so that the false welding problem in the general surface welding is solved, the welding is better and the electrical connection reliability of the product is greatly improved. The three-buckling point design of the casing and the base results in more reliable connection between the casing and the base, and greatly prolongs the service life of the micro USB connector plug.

Description

Micro USB connector plug

Technical field

The utility model relates to the USB connector plug, particularly a kind of Micro USB connector plug of Type B interface.

Background technology

The design miniaturization day by day of existing portable digital product, general Mini USB interface can't satisfy the needs of digital product miniaturization development at present, and it is replaced by the Micro USB connector plug of interface littler (volume is littler) gradually.Micro usb 5pin Type B plug is a kind of plug of international interface standard, its design assembly precision and performance requirement are very high, therefore handling its electricity in the very little Micro USB connector plug of volume, to touch the fixing and welding job of terminal very difficult, its reason: it is very little and be not easy fixedly tin cream at first to be that general electricity touches the terminal tails area, causes rosin joint easily; Next is that to touch terminal be elongated riglet shape to electricity, electricity touches fixedly not the having anticreep design of terminal and pedestal and fastening inadequately, plug often plug can to make electricity touch terminal loosening and influence its signal of telecommunication transmission, make the signal of telecommunication of the transmission that touches terminal unstable or interrupt.And metal shell that existing pedestal front end connects and pedestal adopt two sides single button point connected mode, wherein snapping point is positioned at the centre of housing joint, thereby its fastening power is less, long-term plug is become flexible easily or is got loose, and above reason makes existing Micro usb 5pin Type B plug that generally only be arranged 10000 times plug useful life.

The utility model content

For addressing the above problem, the utility model is intended to propose a kind of Micro USB connector plug.

The technical scheme in the invention for solving the above technical problem is: Micro USB connector plug, the plate socket of housing and pedestal front portion is fixed, and is fitted with electricity in the pedestal and touches terminal group, after each terminal tail end inserts beyond the Great Wall slot and expose; The pedestal both sides respectively are equipped with a grab, and the afterbody of grab plugs together with the back plug; It is characterized in that: the holding section of each terminal is provided with the stuck point of two projectioies, tail portion of terminal be provided with one with the solder side of terminal lateral vertical.

Electricity of the present utility model touches terminal group to be made up of five terminals, constitutes Micro usb 5pin Type B plug; The L type tongue piece that the housing extension goes out engages with shallow the rising as high as the banks on the pedestal, shallow the rising as high as the banks of pedestal one side is provided with a projection, be provided with two projections in shallow the rising as high as the banks on the pedestal another side, position on the corresponding tongue piece of projection is provided with the hole clipping that is connected with its buckle, make housing be placed in plate and form 3 fastenings with the shallow portion of rising as high as the banks on two sides on the pedestal, 3 fastenings make housing more firm with being connected of pedestal.

The beneficial effects of the utility model are: by electricity is touched terminal the fixing position carry out two stuck points designs, make the jack interference fit on terminal and the pedestal, and two stuck points and jack form hangnail, can stop terminal to retreat, each terminal tails is provided with the right angle solder side that can increase bonding area simultaneously, solve the problem that the welding of common plane easily produces rosin joint, made welding better, improved the reliability of the electrical connection of product greatly; And the three buttons point snap-fit design of housing and pedestal, connection between the two is more reliable, improves useful life of the present utility model greatly.

Embodiment

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

As Fig. 1～Micro USB connector plug shown in Figure 3, by housing 100, pedestal 200, electricity touches terminal 300, grab 400 and back plug 500 are formed, plate 201 sockets of housing 100 with pedestal 200 front portions, the projection 203 that shallow on hole clipping that the tongue piece 101 of housing 100 extensions is provided with 102 and the pedestal 200 risen as high as the banks in 202 fastens, as shown in Figure 4 and Figure 5, wherein pedestal 200 fronts form projections 203 and detain points with the list that hole clipping 102 fastens, rise as high as the banks in 202 at pedestal 200 reverse side shallow, form two each and every one projections 203 and two button points that two hole clippings 102 fasten, make housing 100 and pedestal 200 be fastenedly connected; Pedestal 200 both sides respectively are equipped with a grab 400, and the afterbody of grab 400 plugs together with back plug 500; As Fig. 1 and shown in Figure 6, being fitted with one group of five electricity touches terminal 300 at interval in the pedestal 200, the holding section of each terminal 300 is provided with the stuck point 301 of two projectioies, jack interference fit on terminal 300 and the pedestal 200, and two stuck points 301 form hangnail with jack, can increase 200 pairs of terminals 300 of pedestal and retreat resistance, it is more reliable that its electricity is touched, and increases its useful life greatly; The afterbody of each terminal 300 be provided with one with the solder side 302 of terminal 300 lateral vertical, each terminal 300 tail end inserts the slot of back plug 500, and makes solder side 302 expose slot on the back plug 500 for welding; Solder side 302 forms the right angle with terminal 300 sides, being provided with of solder side 302 solved the problem that the conventional planar welding easily produces rosin joint, make welding better, make electrical connection of the present utility model more reliable, increase its useful life greatly, the durability that its plug connects rises to 16000 times from 10000 times.
