Place tilts, and the setting of slope surface 111 can further increase the contact area of recess 111 and glue position 21, strengthen the connection between it,
Meanwhile when the injection molding of glue core 2 before progress, slope surface 111 can play the impact force generated when the injection molding of preceding glue core 2 certain
Cushioning effect prevents the impact force generated when injection molding from causing very much the damage of recess 111 greatly to the instant impact of recess 111.
The shape of glue position 21 and the shape of recess 111 match, and glue position 21 is pressed together on recess 111 so that 21 He of glue position
Recess 111 is connected, as a result, the end of one end of the terminal 11 on upper terminal row 101 can be flush-mounted in preceding glue core 2, under
The end of one end of the terminal 11 in terminal block 102 is also flush-mounted in preceding glue core 2.Then glue core 3 it is upper after glue core 31 and it is lower after
Locating piece 30 is equipped on glue core 32, the other end of the terminal 11 of upper terminal row 101 is stretched from the locating piece 30 of upper rear glue core 31
Go out, the other end of lower terminal row 102 then stretches out from the locating piece 30 of lower rear glue core 32, and the setting of locating piece 30 can be further
The fixation reliability to terminal 11 is improved, terminal 11 is reduced and situations such as displacement, dislocation occurs, can also facilitate the behaviour such as subsequent welding
Make.
And male terminal contact site 112 is equipped on all terminals 11, male terminal contact site 112 is adjacent to and glue
The part of 21 connection of position, and the top surface of the top surface of male terminal contact site 112 and glue position 21 is in same level.As a result,
Glue position 21 can be effectively prevented the insertion of USB male joint is caused to hinder when USB male joint is inserted into, ensure that male terminal connects with this
Contact portion 112 can be realized with the terminal of male connector and be contacted.
Glue core 32 is equipped with the first connecting pole 321 and the second connecting hole 322 after lower, and upper rear glue core 31 is equipped with the second connecting pole
311 and first connecting hole 312, the shape and position phase of the shape and position and the first connecting hole 312 of the first connecting pole 321
Match, and the first connecting pole 321 is installed in the first connecting hole 312, the shape of the second connecting pole 311 and position and the second connecting hole
322 shape and position match, and the second connecting pole 311 is installed in the second connecting hole 322, as a result, lower rear 32 He of glue core
Glue core 31 has passed through to be correspondingly connected with column and realize with the connection of connecting hole and be fixedly connected after upper.
Middle intermediate plate 5 is then passed through by the first connecting pole 321 and the second connecting pole 311, and middle intermediate plate 5 is installed on rear glue core
Between 31 and lower rear glue core 32.Middle intermediate plate 5 can prevent from being in contact between upper terminal row 101 and lower terminal row 102, anti-with this
Situations such as short circuit only occurs between upper terminal row 101 and lower terminal row 102, to ensure the functional reliability of the utility model.
Shell 4 includes then housing main body 41, link block 42 and fixed feet 43, link block 42 and fixed feet 43 and housing main body
41 are integrally formed, and fixed feet 43 is multiple, and all fixed feets 43 are arranged in parallel.Link block 42 is folded into towards 4 inside of shell so that
Shell 4 can be in such a way that link block 42 blocks rear glue core 3, and realization link block 42 is fixedly connected with rear glue core 3, and makes outer
Shell main body 41 can entirely cover the other structures of the utility model, be protected to a certain extent to other structures with this,
And fixed feet 43 can be then inserted into the structures such as circuit board so that shell 4 can be fixed in the structures such as circuit board with this, to
Realize the fixation of the utility model.
When the utility model is used, the terminal 11 stretched out from the locating piece 30 of upper rear glue core 31 on upper terminal row 101
End can connect with circuit board by the modes such as welding, lower terminal, which is arranged, stretches on 102 from the lower locating piece 30 of glue core 32 afterwards
The end of the terminal 11 gone out can also be connect by modes such as welding with circuit board.And the fixed feet 43 of shell 4 can be fastened on electricity
On the plate of road, the fixation of the utility model on circuit boards is realized with this.
When USB male joint needs and the utility model is attached, due to the glue position 21 of preceding glue core 2 in the utility model
Top surface and the top surface of male terminal contact site 112 are in same level, and thus USB male joint can not be by the resistance of preceding glue core 2
Hinder and be smoothly inserted into the utility model so that the terminal in USB male joint can be with the public affairs on the terminal 11 in the utility model
Joint terminal contact site 112 is in direct contact, and the electric connection of USB male joint and the utility model is realized with this, in order to realize difference
It is mounted with the work such as charging, the data transmission between the utility model and two electronic products of USB male joint.
On the other hand, the utility model in use, even if USB male joint and its carried out multiple plug, due to
The end of all terminals 11 in the utility model is fixed by preceding glue core 2, and terminal 11 always can be by the pressure of preceding glue core 2
Power, glue core 2 before the terminal 11 in the utility model will not be detached from due to the traction by USB male joint as a result, it is therefore prevented that this practicality is new
There is a situation where stick up to turn over and burst bad for terminal 11 in type so that the utility model has the high life.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to this practicality
Novel protection domain.
