Third limit protrusion 13.The effect of locking card 9 is filling accommodating chamber 7, after locking card 9 is installed in place, the second limit thereon
Position protrusion 12 is engaged by clamping with the third limit protrusion 13 in accommodating chamber 7, prevents locking card 9 from loosening, it is preferable that blocking part 10
Thickness is equal with the width of accommodating chamber 7, i.e., after blocking part 10 is fully inserted into accommodating chamber 7, one side and the harness of blocking part 10 are pacified
Dress portion 5 abuts, and another side abuts with clamping portion 6, i.e., the clamping portion 6 of wire bundle plug-in connector 2 without normal direction close to the direction of harness mounting portion 5
Mobile, so under any circumstance, the first buckling groove 8 can not be all detached from the first limit protrusion 4, on the one hand can prevent harness
Plug-in unit 2 loosens, and on the other hand can also protect clamping portion 6, prevents it because outer force effect is broken, extends its service life.
It is preferably carried out in mode in one kind, as shown in Figure 5 and Figure 6, on the face that harness mounting portion 5 is connect with clamping portion 6
If there are two side shield 14, two side shields 14 are separately positioned on the both sides of clamping portion 6, on the lateral wall of two side shields 14
Equipped with guide groove 15, there is the guide rod (not shown) coordinated with guide groove 15, side block on the inner wall of electric appliance end connecting seat 1
The setting of plate 14 can play guiding role, and clamping portion 6 is made to be only capable of moving between two side shields 14, improve the first buckling groove
5 and first limit protrusion 4 coordinate precision.On the one hand the setting of guide groove 15 is played the role of installation and is oriented to, on the other hand
It can be limited on (left and right directions described herein is for left and right directions shown in Fig. 4) in left and right directions, prevent line
Beam plug-in unit 2 moves in left-right direction in installation cavity 3, improves assembly precision.
Further, the face of harness mounting portion 5 towards clamping portion 6 is equipped with straight slot 16, and straight slot 16 is along the grafting side of locking card 9
To arrangement, third limit protrusion 13 is arranged in straight slot 16.The setting of straight slot 16 can be played the role of being oriented to for locking card 9,
Block 9 when mounted when locking, third limit protrusion 13 thereon just coordinates with straight slot 16, is slided along straight slot 16, improves security protection
The installation accuracy of pine card 9.For the ease of the installation of locking card 9, it is preferable that the second limit protrusion 12 and third limit protrusion 13 are equal
Using trapezium structure.
It is preferably carried out in mode in another kind, as shown in Figure 7 and Figure 8, blocking part 10 is made of stock 19 and quarter butt 18,
Quarter butt 18 is set to one end of stock 19, and the other end of stock 19 is fixedly connected with baffle 11, and quarter butt 18 is parallel with baffle 11, baffle
It is set on 11 sides being connect with stock 19 there are two the kelly 21 being arranged symmetrically relative to stock 19, the free end of kelly 21 is along oblique
To extending to quarter butt 18 (being not connected to quarter butt 18)；The inner wall of electric appliance end connecting seat 1 is equipped with the to be engaged by clamping with kelly 21
Two buckling grooves；Side shield 14 has escape groove 17 close to one end that accommodating chamber 7 is open.Can greatly it be simplified using the structure anti-
The structure of pine card 9 can further increase the structural stability of locking card 9, prevent it from loosening by the setting of kelly 21.For
Convenient for the dismounting of locking card 9, it is preferable that baffle 11 is equipped with dismounting slot 20, and the cross sectional shape of dismounting slot 20 is rectangle.It is logical
The setting for crossing dismounting slot 20 can easily dismantle locking card 9 very much, and the head of straight screwdriver need to be only inserted into dismounting slot 20
It is interior, dismounting slot 20 is then agitated, so that it is moved and can be removed to the direction for being detached from accommodating chamber 7, since blocking part 10 is by growing
Bar 19 and quarter butt 18 are constituted, therefore it has preferable elasticity, and elastic change can be generated well when mounting and dismounting locking card 9
Shape is without damaging；Kelly 21 also has preferably elasticity simultaneously, will not be damaged because of demolition, installation.
