Abstract

The utility model discloses a Micro universal serial bus (USB) plug, and belongs to the technical field of USB connectors. The Micro USB plug comprises a shell, a pedestal, a clamping hook and electric contact terminals; the shell is sleeved with the front part of the pedestal and fixedly connected with the pedestal through the clamping hook; the tails of the electric contact terminals are integrally formed in a terminal seat through plastic, so that stability and reliability of the Micro USB plug structure are improved, and assembly of the plug is simplified; and the terminal seat is matched with the pedestal and sleeved in the pedestal, the tails of the electric contact terminals are exposed out of the terminal seat and arranged in parallel to form a straight line, so that wire welding can be completed at one tie, assistance of a jig is not required, and poor welding caused by flowing of a welding cup tin foil is avoided at the same time.

Description

The Micro USB plug

Technical field

The utility model relates to the USB connector technical field, particularly a kind of Micro USB connector plug.

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 littler Micro USB connector of interface 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; Because its volume is very little, therefore in Micro USB connector plug, handling its electricity, to touch the fixing and welding job of terminal very difficult.A kind of Micro USB connector is disclosed like Chinese patent CN200920029829.9; Include housing, pedestal, splicing ear and back plug; The anterior plate socket of housing and pedestal is fixed, and is fitted with terminal group in the pedestal, 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; The holding section of each terminal is provided with the stuck point of two convexities, tail portion of terminal be provided with one with the solder side of terminal lateral vertical.This Micro USB connector need splicing ear, pedestal and after the reliability and stability that a lot of corresponding screens structures guarantee connector construction are set, complex structure, assembling inconvenience beyond the Great Wall; Even more serious problem is, this type of Micro USB connector terminal tails all is two column distributions, and the weldering cup of connector is distributed in positive and negative two faces; During bonder terminal afterbody bonding wire, need wire rod be made the tinfoil paper fusing according to paying in connector weldering cup surface, heating then; Tin is climbed according to paying in wire surface; Accomplish welding, yet this type of Micro USB connector can't weld two faces on the one hand simultaneously, need welding at twice; And the winding displacement on two sides needs to fix by tool during bonding wire, twice bonding wire labor man-hour; On the other hand, in welding during winding displacement, the tinfoil paper of following row's weldering glass can melt and flow away, and vice versa, thereby cause the winding displacement failure welding.

The utility model content

The purpose of the utility model Micro USB plug is to simplify the assembling of Micro USB connector, and the problem that exists when solving its bonding wire.

The utility model addresses the above problem the technical scheme that is adopted: the Micro USB plug; Comprise that housing, pedestal, grab and electricity touch terminal; Said housing also is fixedly connected through grab with the anterior socket of pedestal; Said electricity touch tail portion of terminal through the plastic cement integrated molding in a terminal base, said terminal base cooperates with said pedestal and is socketed in the said pedestal, the tail end that said electricity touches terminal exposes said terminal base and is arranged in a straight line side by side.

The tail end that the electricity of the utility model touches terminal is one to be wider than electricity and to touch the anterior solder side of terminal, and solder side is parallel to the terminal base plane; It is five that electricity touches terminal, constitutes Micro USB 5pin Type B plug; Hole clipping on the tongue piece that the housing extension goes out engages with the projection of being located at said pedestal one side, and the projection that the one side of said terminal base is provided with engages with the interior buckle of pedestal.

The beneficial effect of the utility model is: electricity is touched terminal pass through the plastic cement integrated molding in terminal base, improved the reliability of Micro USB plug structure, compare the setting that prior art has been saved back plug, assembling is simplified; The tail end that each electricity touches terminal is arranged in a straight line, and can once accomplish bonding wire, and does not need tool auxiliary, has avoided the mobile failure welding that causes because of weldering cup tinfoil paper simultaneously.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation:

Fig. 1 is the STRUCTURE DECOMPOSITION figure of the utility model;

Fig. 2 touches the structural representation of terminal for the utility model electricity.

Embodiment

Micro USB plug as shown in Figure 1; Comprise that housing 1, pedestal 2, two groups of grabs 3 and electricity touch terminal 4; Front portion 201 sockets of said housing 1 and pedestal 2; Hole clipping 102 on the tongue piece 101 that this housing 1 extension goes out engages with the projection (not shown) of being located at said pedestal 2 one sides, is fixedly connected in pedestal 2 both sides through two groups of grabs 3 between housing 1 and the pedestal 2; The afterbody that said electricity touches terminal 4 passes through the plastic cement integrated molding in a terminal base 5, and said terminal base 5 cooperates with said pedestal 2 and is socketed in the said pedestal 2, and the projection 501 that the one side of this terminal base 5 is provided with engages with pedestal 2 interior buckles (not shown); The tail end 401 that said electricity touches terminal 4 exposes said terminal base 5 and is arranged in a straight line side by side, and electricity to touch terminal 4 be five, constitute Micro USB 5pin Type B plug; The tail end that touches terminal 4 like the described electricity of Fig. 2 is one to be wider than electricity and to touch the anterior solder side 401 of terminal 4, and this solder side 401 is parallel to terminal base 5 planes.

Above embodiment only supplies to explain the usefulness of the utility model; But not to the restriction of the utility model; Those skilled in the art; Under the situation of spirit that does not break away from the utility model and scope, the technical scheme of having done various equivalents or variation should belong to the protection category of the utility model, is limited each item claim.
