Summary of the invention
The object of this invention is to provide a kind of industrial computer plug device with fuse, its industrial computer joint that can automatically realize having more contact pin carries out grafting.
According to the present invention, a kind of industrial computer plug device with fuse, comprises slot support body, the slot be fixedly connected with slot support body and plug; The end of plug is connection header, and the connection end face of connection header is fixed with pin groups, and the end of described slot is the end plates that can engage with described connecting end surface, is provided with the insertion hole groups that can coordinate with described pin groups in described slot;
Wherein, described pin groups comprises the first contact pin, the second contact pin and the 3rd contact pin, first contact pin is distributed in two outward flange sides of described connecting end surface, described 3rd contact pin is distributed in the middle of described connecting end surface, described second contact pin is distributed in the position offset in the middle of described two outward flange side direction of described connecting end surface, thus between described first contact pin and described 3rd contact pin; The length of described first contact pin, the second contact pin the 3rd contact pin reduces successively, around backing down spring on described first contact pin, described in back down spring extends to described first contact pin in its natural state intermediate length position from described connecting end surface; Described connection header back both sides relative with described connecting end surface are provided with stepped profile, fuse is provided with below described connection header, described fuse top is provided with the first joint, is provided with the second joint bottom described fuse, and the described first joint other end is connected with bottom connection header.
Jack in described insertion hole groups is divided into guide section and conductivity section, and described stepped profile is used for coordinating with the expansion roller device of the both sides being symmetricly set in described slot support body, thus is inserted in the described jack of described insertion hole groups described pin groups piecewise.
Pass through such scheme, because the contact pin that have employed different-diameter rugosity is arranged, it carries out the location of each rank simultaneously when thicker contact pin can be utilized to insert, and, the location degree of contact pin is corresponding with the curve of the outline of plug, can carry out different contact pin location in the different insertion stages.Contact pin segmentation can make location separate with conductivity function, avoids the formation of signal of telecommunication interference.
Embodiment
Below in conjunction with Fig. 1-5, the present invention is described in detail.
With an industrial computer plug device for fuse, comprise slot support body 1, the slot 2 be fixedly connected with slot support body and plug 12; The end of plug 12 is connection header 13, the connection end face of connection header 13 is fixed with pin groups 14, the end of described slot 2 is the end plates 24 that can engage with described connecting end surface, is provided with the insertion hole groups that can coordinate with described pin groups 14 in described slot 2;
Wherein, described pin groups 14 comprises the first contact pin 141, second contact pin 142 and the 3rd contact pin 143, first contact pin 141 is distributed in two outward flange sides of described connecting end surface, described 3rd contact pin is distributed in the middle of described connecting end surface, described second contact pin 142 is distributed in the position offset in the middle of described two outward flange side direction of described connecting end surface, thus between described first contact pin 141 and described 3rd contact pin 143; The length of described first contact pin 141, second contact pin 142 the 3rd contact pin 143 reduces successively, around backing down spring 1410 on described first contact pin 141, described in back down spring 1410 extends to described first contact pin 141 in its natural state intermediate length position from described connecting end surface; Described connection header 13 back both sides relative with described connecting end surface are provided with stepped profile, fuse 1301 is provided with below described connection header 13, described fuse 1301 top is provided with the first joint 1302, be provided with the second joint 1303 bottom described fuse 1301, described first joint 1302 other end is connected with bottom connection header 13.
Jack in described insertion hole groups is divided into guide section 222,, 232 and conductivity section 221,231, described stepped profile is used for coordinating with the expansion roller device of the both sides being symmetricly set in described slot support body 1, thus is inserted in the described jack of described insertion hole groups described pin groups 14 piecewise.
Wherein, described stepped profile is divided into two, symmetrically arranged left and right portion's section, each Duan Cong is divided into the first planar section 132, second planar section 134 and the 3rd planar section 135 successively on described connecting end surface to the direction away from described connecting end surface, the first bevel phase 131 is provided with between described connecting end surface and described first planar section 132, between the first planar section 132 and the second planar section 134, be provided with the second bevel phase 133, between the second planar section 134 and the 3rd planar section 135, be provided with the 3rd bevel phase 136.
Wherein, described first contact pin 141 mates with the first fixed via 21 being arranged at described end plates 24 two ends, described second contact pin 142 is corresponding with the second jack 22 be arranged in slot 2, and described 3rd contact pin 143 is corresponding with the 3rd jack 23 be arranged in described slot 2; Wherein, described second jack 22 is divided into the second jack guide section 222 and the second jack conductivity section 221, and described 3rd jack 23 is divided into the 3rd jack guide section 232 and the 3rd jack conductivity section 231.
The using method of described plug device, comprises the steps:
First described first contact pin 141, inserts in described first fixed via 21 by a;
Plug 2 is inwardly pushed by described first bevel phase 131 by the roller 8 of expansion roller device described in b, thus the second contact pin 142 stretches in the second jack guide section 222 of the second jack 22, and now, roller 8 engages with the first planar section 132;
C when roller 8 continues through coordinate with the second bevel phase 133 and plug 12 continued inwardly to push time, second contact pin 142 coordinates with the second jack conductivity section 221, and the 3rd contact pin 143 stretches in the 3rd jack guide section 232 of the 3rd jack 23, now, roller engages with the second planar section 134;
When roller, by described 3rd bevel phase 136, after engaging with the 3rd planar section, described 3rd contact pin 143 coordinates with the 3rd jack conductivity section 231 of the 3rd jack 23 d.
Wherein, described expansion roller device comprises driving leading screw 3, the screw slide block 5 with driving leading screw 3 threaded engagement, the rod member 6 be connected with screw slide block 5 and the described roller 8 be connected with rod member 6.
Described roller 8 can be in and hold in recess 10 after being contracted, to abdicate the passage passed through for plug 12.
Wherein, described second contact pin 142 and the 3rd contact pin 143 each one be all divided into the contact 1421 that conducts electricity of end, 1431 and with the adjacent insulating material of connecting end surface coated section 1422,1432.
Introduction part the 223, three jack 23 that introduction part 213, second jack 22 that first fixed via 21 has a taper has a taper has the introduction part 233 of taper.
