Specific embodiment
Below in conjunction with the attached drawing specific embodiment that the present invention will be described in detail, those skilled in the art is made to become apparent from geography
How solution practices the present invention.Although describing the present invention in conjunction with its preferred embodiment, these embodiments are
It illustrates, is not intended to limit the scope of the invention.
Referring to Fig. 1 and Fig. 2, the ground connection fool proof pin composite construction of a kind of electrical cabinet cabinet, including chassis shell body 1, pcb board 2,
Socket 3, plug 4, male pin 5, earth plate 6 and female pin 7；The pcb board 2 is set in chassis shell body 1, and the socket 3 is fixed
It is installed in chassis shell body 1, the plug 4 is fixedly installed on pcb board 2；One end of the socket 3 is installed by male pin 5, the public affairs
Pin 5 is equipped with ground hole 501, and earth plate 6 is installed at the corresponding end of the plug 4, and the earth plate 6 connects with pcb board 2
It connects, female pin 7 is installed on earth plate 6, mother's pin 7 is equipped with jack, and the jack is interior to constitute hat spring embedded with hat spring 701
Jack；The end inserting of the male pin 5 is connected in the hat spring socket on female pin 7, so that socket 3 and 4 inserting of plug connect
It connects.
Wherein, the pcb board 2 is installed on a panel 8, and the panel 8 constitutes complete cabinet with chassis shell body 1.
The assembly of the pcb board 2 and chassis shell body 1 is referring to Fig. 3, and arrow is the inserting direction of pcb board 2 in Fig. 3, it is therefore an objective to
Connect plug 4 with 3 inserting of socket.If inserting is correct, referring to fig. 4, male pin 5 can be correctly inserted into female pin 7, to make plug
4 are connected with socket 3, and correctly lid closes the panel 8 and chassis shell body 1 that pcb board 2 connects.If inserting mistake, referring to box in Fig. 5
Part, panel 8 at this time are located at outside chassis shell body 1 every living, and panel 8 cannot correctly lid closes with chassis shell body 1, in conjunction with Fig. 6,
Female 7 position of pin it is not corresponding with 5 position of male pin and can not inserting connection, female pin 7 is butted on socket 3, and leads to plug 4
Socket 3 cannot be inserted into, it can be determined that plug 4 is 180 ° reverse.
In the specific implementation, the aperture of the jack on female pin 7 is equipped with chamfering, and the chamfering is greater than 45 ° and is less than etc.
In 75 °, preferably 60 °, such chamfering constitutes long chamfering 702；The end of the male pin 5 is round end 502.In actual use,
Male pin 5 and female pin 7 are concealed in that in chassis shell body 1, can not see its inserting situation, so good in the case where blindmate
Guiding role just seems particularly important, therefore the long chamfering 702 and round end 502 that design can play good guiding role, so that
Inserting lubrication is unobstructed.
One end of mother's pin 7 is equipped with external screw thread, and the jack is arranged in the other end of female pin 7；It is set on the earth plate 6
There is the threaded hole connecting with one end of female pin 7, one end of the socket 3 is equipped with to be adapted with the other end size of female pin 7
Card slot 301, if inserting is correct, the other end of mother's pin 7 can be just inserted into card slot 301, if inserting mistake, female pin
7 other end can be butted on socket 3, such plug 4 and socket 3 just can not inserting connect.
The socket 3 is fixedly installed in chassis shell body 1 by fastening screw and the pluggable side of socket 3 is in chassis shell body
Inside 1, one end of the socket 3 and the corresponding section of chassis shell body 1 offer the pin hole being inserted into for male pin 5 respectively, exist in this way
When installing socket 3 in chassis shell body 1, the pin hole that male pin 5 is inserted into socket 3 and chassis shell body 1 can play fool proof and positioning
It acts on, then screw on fastening screw socket 3 can be fixed in chassis shell body 1.It is inserted for being inserted into hat spring one end of the male pin 5
In hole and it is located in chassis shell body 1, the other end of male pin 5 is arranged the ground hole 501 and is located at outside chassis shell body 1.
The plug 4 is fixedly installed on pcb board 2 by fastening screw, the 6 place end of earth plate on plug 4 it is tight
Gu screw 9 is connect with earth plate 6, so that earth plate 6 electrically conducts with pcb board 2.
Since the chassis shell body 1 of plastic material cannot be conductive, it is connect by male pin 5 with the inserting of female pin 7, realizes PCB
Electrically conducting between plate 2, earth plate 6, female pin 7 and male pin 5.In actual use, connect male pin 5 and female 7 inserting of pin
It connects, and is grounded in the ground hole of male pin 5 501, can be achieved with grounding function.Moreover, because male pin 5 and female pin 7 are pacified respectively
Corresponding end loaded on socket 3 and plug 4, male pin 5 connect with the inserting of female pin 7 and play mechanical foolproof function, avoid even
Faulty operation when combination hub 3 and plug 4, to can guarantee that socket 3 is correctly connect with plug 4, pcb board 2 is correctly installed on machine
In tank shell 1.
The chassis shell body 1 is expected using the PC of tool high intensity and coefficient of elasticity, high impact；The earth plate 6 can
Using brass material, conduct electricity very well, current-carrying capability it is strong；Mother's 7 main material of pin is brass, and hat 701 material of spring is beryllium
Copper, the current-carrying capability that not only conducts electricity very well is strong, but also elastic property is good, can repeatedly plug indeformable, long service life；It is described
Male pin 5 is brass copper rod, and the sturdy not only current-carrying capability of barred body is strong but also high mechanical strength is not easy to be pushed up disconnected, and the internal screw thread of tail portion can
Earth lead is coupled, mating is stablized.
It should be noted that chassis shell body 1 is other than being plastic material, chassis shell body 1 can also be it is nonconducting other
Material.Earth plate 6 is conductive outer except through fastening screw and pcb board 2, can also come with connection inside plug 4 conductive.
It should be pointed out that can also have the embodiment of a variety of transformation and remodeling for the present invention through absolutely proving,
It is not limited to the specific embodiment of above embodiment.Above-described embodiment as just explanation of the invention, rather than to this
The limitation of invention.In short, protection scope of the present invention should include that those are apparent to those skilled in the art
Transformation or substitution and remodeling, and be determined by the appended claims.
