Technical solution used by charging plug disclosed by the utility model is:

A kind of charging plug, including PCB circuit board, the PCB circuit board are equipped with single side terminal, the PCB circuit board Middle part offers link slot, and the PCB circuit board end is fixed with shell, and the shell is that upper end offers contact mouth and rear end The semi-surrounding structure of insert port is offered, the side of the PCB circuit board and the inside of shell are by being welded and fixed, the PCB Black glue is filled between wiring board and shell.

Preferably, the black glue material is ABS.

Preferably, the link slot of the PCB circuit board is S type groove.

Preferably, the opening width of the shell insert port be less than shell on the inside of width, the insert port with Ladder is formed on the inside of shell.

Preferably, the shell is integrally formed.

Preferably, the shell two sides are equipped with positioning groove.

Preferably, the outer casing back is equipped with positioning convex platform.

Preferably, the outer casing bottom offers sagittate through-hole.

A kind of beneficial effect of charging plug disclosed by the utility model is: by the way that single side terminal is arranged in PCB circuit board, Cost can be effectively saved, improves production efficiency, then protect single side terminal by shell, PCB circuit board passes through insert port It is inserted into shell, then PCB circuit board and shell is fixed by soldering, finally filled out between PCB circuit board and shell Fill black glue.The single side terminal of PCB circuit board is exposed by contact mouth, when being inserted into electronic product, plays the work of electric connection With.It is in semi-surrounding structure by shell, is connected firmly with PCB circuit board end, and protection is played to PCB circuit board end and is made With, meanwhile, company that is more easy, and passing through PCB circuit board is filled in the black glue of semi-surrounding structure and PCB circuit board by shell Black glue is filled in access slot, keeps PCB circuit board more secured with cage connection, effectively reduces processing cost, reduces production cost.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of charging plug of the utility model.

Fig. 2 is a kind of structural schematic diagram of the PCB circuit board of charging plug of the utility model.

Fig. 3 is a kind of structural schematic diagram of the shell of charging plug of the utility model.

Specific embodiment

The utility model is further elaborated and is illustrated with Figure of description combined with specific embodiments below:

Fig. 1-Fig. 3, a kind of charging plug, including PCB circuit board 10 are please referred to, PCB circuit board 10 is equipped with single side terminal 11, link slot 12 is offered in the middle part of PCB circuit board 10, the link slot 12 of PCB circuit board 10 is S type groove, and the black glue 30 of filling can To connect after S type groove with the bottom of shell 20, keep PCB circuit board 10 and the connection of shell 20 more secured.PCB circuit board 10 ends are fixed with shell 20, and shell 20 is that upper end offers contact mouth 21 and rear end offers the semi-surrounding knot of insert port 22 Structure, more convenient when mould filling black glue 30, corresponding grinding tool manufacture is more simple, cost-saved.PCB circuit board 10 Side and the inside of shell 20, which pass through, to be welded and fixed, and black glue 30,30 material of black glue are filled between PCB circuit board 10 and shell 20 Thermosetting performance for ABS, ABS is stablized, and bond properties is good, and has very strong insulating properties.

Shell 20 is integrally formed, and reduces NC Machining Process, save the cost.The opening width of 20 insert port 22 of shell is small Ladder is formed on the inside of width in 20 inside of shell, insert port 22 and shell 20, after filling ABS, stepped portion has ABS Force keeps the connection of shell 20 more secured.

20 two sides of shell are equipped with positioning groove 23, and 20 rear end of shell is equipped with positioning convex platform 24, and 20 bottom of shell offers arrow The through-hole 25 of head.The charging end that electronic product is fixed by positioning groove 23 is passing through the control insertion of positioning convex platform 24 Depth avoids the charging end of damage electronic product, then the direction of plug is indicated by through-hole 25.

In above scheme, by the way that single side terminal 11 is arranged in PCB circuit board 10, cost can be effectively saved, production effect is improved Rate, then protected single side terminal 11 by shell 20, PCB circuit board 10 is inserted into shell 20 by insert port 22, then PCB circuit board 10 and shell 20 are fixed by soldering, finally fill black glue between PCB circuit board 10 and shell 20 30.The single side terminal 11 of PCB circuit board 10 is exposed by contact mouth 21, when being inserted into electronic product, plays electric connection Effect.It is in semi-surrounding structure by shell 20, is connected firmly with 10 end of PCB circuit board, and 10 end of PCB circuit board is played Protective effect, meanwhile, it is more easy in the filling of the black glue 30 of semi-surrounding structure and PCB circuit board 10 by shell 20, and pass through Black glue 30 is filled in the link slot 12 of PCB circuit board 10, is connect PCB circuit board 10 with shell 20 more secured, is effectively reduced Processing cost reduces production cost.

Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this The spirit and scope of utility model technical solution.
