Abstract

The utility model discloses an improved USB socket which comprises an insulating block, a pin arranged on the insulating block, and a fixation iron casing sheathed on the insulating block. At least one auxiliary fixation weld leg is arranged below the fixation iron casing, and the auxiliary fixation weld leg and the fixation iron casing are integrally molded. A circuit board corresponding to the USB socket is provided with an auxiliary fixation hole which is corresponding to the auxiliary fixation weld leg. With the soldering and welding of the auxiliary fixation weld leg and the auxiliary fixation hole, the auxiliary fixation of the middle position of the USB socket can be completed, and the cooperation with a number of fixation weld legs which extend out from both sides of the fixation iron casing of the USB socket is realized, thus the USB socket is fixed. According to the utility model, the improved USB socket is stable and reliable; the auxiliary fixation weld leg and the fixation iron casing are integrally molded; and the improved USB socket has the advantages of simple structure, convenient welding, high practicality and long service life.

Description

A kind of modified model USB socket

Technical field

The utility model relates to a kind of USB socket, particularly a kind of modified model USB socket.

Background technology

The USB interface is as a kind of standard interface of transmission signals; Be widely used in the electronic equipment, for example: USB flash disk interface, computer output/input interface, printer input/output interface, mobile phone connecting line interface and digital camera data line interface or the like need earlier USB socket to be fixedly installed on the circuit board (pcb board) at these equipment usually; Fixing means traditionally is; Iron-clad both sides at USB socket are extended with some legs, and circuit board (pcb board) offers in the corresponding welding hole of these legs, fixes through scolding tin at last; The USB socket fixing point of this structure is in both sides; Loosening easily during the USB interface plug, to strengthen fixing though can increase leg, complex structure, welding very trouble are complicated; In addition, also have through on collets, increasing auxiliary leg and strengthen fixing, this mode makes the structure more complicated of USB socket, and the welding difficulty is bigger, and practicality is not high.

Summary of the invention

In order to overcome the deficiency of prior art, the utility model provides a kind of modified model USB socket, and that this USB socket has is simple in structure, the characteristics of convenient welding, secure.

The utility model solves the technical scheme that its technical problem adopted:

A kind of modified model USB socket; It is characterized in that comprising collets, be arranged on the pin on the collets and be sleeved on the fixedly iron-clad on the collets; The below of said fixedly iron-clad is provided with the auxiliary fixing leg of at least one; Said auxiliary fixing leg and fixedly iron-clad is one-body molded offers at least one auxiliary fixing hole corresponding with the auxiliary fixing leg on the circuit board corresponding to this USB socket.

Said auxiliary fixing leg is provided with one, and said auxiliary fixing hole is provided with one.

Said fixedly iron-clad both sides also are extended with the plurality of fixed leg, offer on the said circuit board some with should be fixedly the corresponding fixing hole of leg.

Said fixedly leg is provided with four, and said fixing hole is provided with four.

Said collets below offers the reference column of at least one, offers at least one location hole corresponding with reference column on the said circuit board.

Said reference column is provided with two, and said location hole is provided with two.

The beneficial effect of the utility model: the auxiliary fixing leg of at least one is set below fixing iron-clad, and auxiliary fixing leg and fixedly iron-clad is one-body molded offers the auxiliary fixing hole corresponding with the auxiliary fixing leg on the circuit board corresponding to this USB socket; Scolding tin welding through auxiliary fixing leg and auxiliary fixing hole can be accomplished the auxiliary fixing in USB socket centre position; And with USB socket fixedly the extended plurality of fixed leg in iron-clad both sides cooperate, can accomplish fixing to USB socket, secure; And auxiliary fixing leg and fixedly iron-clad is one-body molded; Structure is very simple, convenient welding, and practicality is high, long service life.

Description of drawings

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

Fig. 1 is the overall structure sketch map of the utility model;

Fig. 2 is the structural representation of the fixedly iron-clad part of the utility model;

Fig. 3 is the structural representation of the collets part of the utility model.

Embodiment

Referring to figs. 1 through Fig. 3, Fig. 1 to Fig. 3 is the structural representation of a specific embodiment of the utility model, and is as shown in the figure; A kind of modified model USB socket comprises collets 3, is arranged on the pin 31 on the collets 3 and is sleeved on the fixedly iron-clad 1 on the collets 3 that fixedly the centre position, below of iron-clad 1 is provided with an auxiliary fixing leg 11; Auxiliary fixing leg 11 is with fixedly iron-clad 1 is one-body molded, and bending to required angle as required, offers the auxiliary fixing hole 21 corresponding with auxiliary fixing leg 11 on the circuit board 2 corresponding to this USB socket; Fixedly iron-clad 1 both sides also are extended with four fixedly legs 12; Offer on the circuit board 2 four with should be fixedly the corresponding fixing hole 22 of leg 12, the USB socket both sides are fixed with the welding of fixing hole 22 scolding tin through fixing leg 12, weld through auxiliary fixing leg 11 and auxiliary fixing hole 21 scolding tin simultaneously and fix USB socket is middle; Can accomplish fixing to USB socket; Secure, and auxiliary fixing leg 11 is with fixedly iron-clad 1 is one-body molded, and structure is very simple; Convenient welding, practicality is high.

Further, as shown in the figure, collets 3 belows offer the reference column 32 of two symmetries; Offer two location holes 23 corresponding with reference column 32 on the circuit board 2, after the utility model welded and installed, reference column 32 clips are in location hole 23; The collets 3 spacing circuit boards 2 that are fixed on; Collets 3 are hit displacement and pin 31 are come off when preventing the USB interface plug once more, duplicate protection, the reliability and the useful life of further improving the utility model.

More than the preferable enforcement of the utility model is specified, certainly, the utility model can also adopt the form different with above-mentioned execution mode, for example auxiliary fixing leg 11 can be provided with one or more; Fixedly leg 12 can a plurality of as required settings; Same reference column 32 also can be provided with one or more as required.So those of ordinary skill in the art should belong in the protection range of the utility model conversion of under the prerequisite of spirit of the present invention, being done that is equal to or corresponding the change.
