Yet, when the connector pressure head 100 ' that use is commonly used carries out pressing, the connector pressure head 100 ' part of pressing is the plastics diapire 25 ' of connector 200 ', when terminal 23 ' is pressed into and deforms, can produce interaction force between terminal 23 ' and the plastics diapire 25 ', it is loosening that terminal 23 ' is taken place.
[summary of the invention]
Main purpose of the present utility model is to provide a kind of terminal of connector that prevents that loosening connector pressure head takes place when the pressing process.
To achieve the above object, the utility model provides a kind of connector pressure head, be applicable on pressing a connector to a circuit board, wherein, this connector is provided with a diapire and is located at plurality of terminals on this diapire, and these terminals are respectively equipped with the resettlement section that is positioned at the diapire top, are fixed in the fixed part of diapire and are positioned at connecting portion below the diapire, wherein, the end of fixed part is convexly set on the diapire, and connecting portion is fixed on the circuit board.
And this connector pressure head comprises a body, but the proper sleeve of this body is in connector, and the face that this body is relative with terminal is provided with some accepting grooves, when making pressing and fixing, can make terminal accommodating portion be arranged in the accepting groove, and make fixed part be fastened in outside the accepting groove, thereby restriction connector pressure head continues to press downward to.
Another purpose of the present utility model is to provide a kind of connector pressure head with fool proof function.Wherein, the connector that is used for pressing takes the shape of the letter U, and the both sides of this diapire vertically extend a first side wall and one second sidewall respectively certainly, and the first side wall and second sidewall are parallel to each other.And the inboard of this first side wall is provided with some strip grooves, and a side of this connector pressure head and outwards convex with some strip projections corresponding to strip groove set on the connector, and these projections just can be in these strip grooves the slippage location.
Compared to prior art, can limit the connector pressure head and directly contact, thereby effectively prevent in the pressing process with the diapire of connector, cause terminal loosening because of interaction between connector diapire and the terminal.Again, two sides of connector pressure head are asymmetric, preventing the random sleeve of user, thereby have the function of fool proof protection.

[embodiment]
See also shown in Figure 2, a connector 200 comprises a plastic body 20, in present embodiment, this plastic body 20 is arranged to U-shaped, plastic body 20 is provided with a diapire 25, this diapire 25 is provided with plurality of terminals 23, and these terminals 23 are that form with matrix is arranged on the diapire 25, on these terminals 23 and the part that is positioned at diapire 25 tops be referred to as resettlement section 231; And on these terminals 23 and the part that is positioned at diapire 25 be referred to as fixed part 232, and the sectional dimension of fixed part 232 is greater than the sectional dimension of resettlement section 231, and the end of fixed part 232 is convexly set on the diapire 25; And on these terminals 23 and the part that is positioned at diapire 25 belows be referred to as connecting portion 233.
In addition, the both sides of this diapire 25 vertically extend a first side wall 21 and one second sidewall 22 respectively certainly, and the first side wall 21 and second sidewall 22 are parallel to each other.Wherein, the inboard of this first side wall 21 is provided with some strip grooves 211, and the inboard of this second sidewall 22 is provided with a block groove 221.
This connector 200 is pressed into by a connector pressure head 100 and is fixed on the circuit board (not icon), and wherein, this connector pressure head 100 comprises a body 10, but these body 10 proper sleeves are in connector 200.And a side of this body 10 and outwards convex with some strip projections 11 corresponding to strip groove 211 places set on the connector 200, and these projections 11 just can be in these strip grooves 211 the slippage location.In addition, set block groove 221 places outwards convex with a block projection 12 in the opposite side of this body 10 and on corresponding to connector 200, and should just can slippage locate in this bulk groove 221 in by bulk projection 12.In addition, this body 10 and terminal 23 relative faces are provided with some accepting grooves 13, and the lateral dimension of these accepting grooves 13 is greater than the lateral dimension of resettlement section 231, but the groove of these accepting grooves 13 is to the lateral dimension of size less than fixed part 232, so make the resettlement section 231 of terminal 23 be arranged in the accepting groove 13, and make the fixed part 232 of terminal 23 be limited to outside the accepting groove 13.In present embodiment, these accepting grooves 13 be shaped as the strip groove, and be parallel to each other between these accepting grooves 13.In addition, also the shape of accepting groove 13 can be arranged to cylindrical grooves, and be arranged in the below of connector pressure head 100 in the mode of matrix.
During pressing, please in conjunction with consulting shown in Fig. 2,3 and 4, earlier connector pressure head 100 is placed in the top of connector 200, and make a side that connector pressure head 100 is provided with strip projection 11 corresponding to the first side wall 21, and connector pressure head 100 is provided with a side of block projection 12 corresponding to second sidewall 22.Then, with connector pressure head 100 downward sleeves to connector 200, in the insertion process, can make strip projection 11 slippage in strip groove 211, and make the slippage in block groove 221 of block projection 12, simultaneously, the resettlement section 231 of terminal 23 can extend in the accepting groove 13 gradually.When this connector pressure head 100 behind sleeve location, the circumference branch of accepting groove 13 is held on the fixed part 232 of terminal 23, thus the bottom 102 of restriction connector pressure head 100 directly contacts with the diapire 25 of connector 200.Like this, when applying pressure to the top 101 of connector pressure head 100, pressure directly is passed to the terminal 23 of connector 200 through connector pressure head 100, and the connecting portion 233 that makes terminal 23 penetrates in the through hole set on the circuit board, be pressed in the process of through hole at connecting portion 233, connecting portion 233 can deform, and is fixed on the circuit board thereby terminal 23 held.
