The quick connector of stability includes connection terminal 10 and plastic body 20.
Specifically, connection terminal 10 includes electrical with the first connecting pin 11 of the plug grafting of external device and pcb board 30
The second connection end 12 of connection, the interlude 13 being connected between the first connecting pin 11 and second connection end 12 and setting exist
Fixed part 14 on interlude 13,20 integrated injection molding of interlude 14 and plastic body；
Fixed part 14 includes the first spiral shell rib 141 and the second spiral shell rib 142 being arranged around the periphery of interlude 13, the second spiral shell rib
At least two fractures 143 for disconnecting the second spiral shell rib 142, and the setting of the interval of fracture 143 are provided on 142.
In the present embodiment, by having the fixed part 14 of the first spiral shell rib 141 and the second spiral shell rib 142 in the setting of interlude 13,
And fixed part 14 is subjected to integrated injection molding with plastic body 20 and is connected, such setting improves connection terminal 10 and plastic body 20
Connection stability, the setting of the first spiral shell rib 141, can avoid connection terminal 10 occur front and back movement, the second spiral shell rib 142
Setting can avoid connection terminal 10 and rotate.
In the present embodiment, the outer weekly interval of the first spiral shell rib 141 opens up jagged 144.Wherein, referring to figure 4., notch
144 include perpendicular to 141 outer peripheral surface of the first spiral shell rib vertical plane 1441, be connected to the first inclined-plane of 141 outer peripheral surface of the first spiral shell rib
1442 and it is connected to second inclined-plane 1443 on vertical plane 1441 and the first inclined-plane 1442；First inclined-plane 1442 and the second inclined-plane
1443 angle is acute angle.
On the one hand the setting of notch 144 increases the connection area of the first spiral shell rib 141 and plastic body 20, on the other hand, erect
It faces 1441 setting directly, so that there are clamping structures for the connection of the first spiral shell rib 141 and plastic body 20, improves the stabilization of connection
Property；In addition, the setting at an acute angle of the first inclined-plane 1442 and the second inclined-plane 1443, equally improves the stability of connection.
Certainly, the angle of the outer peripheral surface of vertical plane 1441 and the first spiral shell rib 141 is also possible to acute angle, such vertical plane 141
An overhead kick structure is just formed with the outer peripheral surface of the first spiral shell rib 141, when the overhead kick structure and plastic body 20 carry out integrated injection molding, is improved
The stability of the two connection.
In the present embodiment, the spacing between the first spiral shell rib 141 is less than the spacing between the second spiral shell rib 142.First spiral shell rib
141 close to the first connecting pin 11, therefore the first spiral shell rib 141 is close extraneous, once the head end of interlude 13 and plastic body 20 occur
Gap, steam will be to the first spiral shell rib 141 be passed through, and therefore, such setting improves the waterproof performance of the present embodiment.
In addition, the rib height of the first spiral shell rib 141 is high less than the rib of the second spiral shell rib 142.On the one hand such setting improves this
On the other hand the waterproof performance of embodiment improves the stability that the second spiral shell rib 142 and plastic body 20 connect.
In the present embodiment, specifically, there are four fractures 143.It is two pairs that four fractures 143, which are divided to, is symmetrical arranged two-by-two.With
Improve the stability that connection terminal 10 and plastic body 20 connect.
In the present embodiment, Fig. 1 and Fig. 5 are please referred to, plastic body 20 includes plastic body 21 and recessed in plastic body
At least one the first fixing groove 211 of 21 peripheral sides and at least one second fixing groove 212, the first fixing groove 211 and second are solid
Determine slot 212 to be used to be fixedly connected with 31 wall of mounting hole of pcb board 30,212 coaxial line of the first fixing groove 211 and the second fixing groove
Setting, and the slot bottom of the first fixing groove 211 and the slot bottom of the second fixing groove 212 flush, and the groove width of the first fixing groove 211 is greater than the
The groove width of two fixing grooves 212.
Wherein, the setting of the first fixing groove 211 and the different groove widths of the second fixing groove 212, is convenient for plastic body 20 and different thickness
The pcb board 30 of degree carries out grafting.Moreover, in pcb board 30 mounting hole 31 corresponding setting, improve plastic body 20 and pcb board 30
The stability of connection.
Further, there are two the first fixing grooves 211, there are two the second fixing grooves 212, two 211 phases of the first fixing groove
To setting, two the second fixing grooves 212 are oppositely arranged.Such setting improves the steady of the connection of plastic body 20 and pcb board 30
It is qualitative.
In the present embodiment, plastic body 20 includes the plug grafting being used for external device being arranged in plastic body 21
Jack 22, the first connecting pin 11 of connection terminal 10 protrudes into jack 22, interlude 13 and 21 integrated injection molding of plastic body at
Type, second connection end 12 stretch out plastic body 21.
The assembling process of the present embodiment is:
Firstly, being arranged connection terminal 10 in injection mold, and pass through injection mold for plastic body 20 and connection terminal
10 13 integrated injection molding of interlude, so that the first spiral shell rib 141 and the second spiral shell rib 142 and plastic body 20 in fixed part 14 are steady
Fixed connection；
Then, according to the thickness of different pcb boards 30, select the first fixing groove 211 or second on plastic body 21 solid
The mounting hole 31 for determining slot 212 and pcb board 30 carries out grafting (the present embodiment is by taking the second fixing groove 212 as an example)；
Finally, the second connection end 12 of connection terminal 10 and pcb board 30 are welded.
The installation process of the present embodiment is just completed in this way.
The quick connector of quick connector compared to the prior art, the high stability of the utility model passes through fixed part
In the first spiral shell rib and the second spiral shell rib setting, and fixed part and plastic body are subjected to integrated injection molding, it is practical new to improve this
