Description
Technical field
The present invention relates to electrical cabinet cabinet technical fields more particularly to the blindmate of electrical cabinet cabinet to be grounded clamping piece structure.
Background technique
Now, the material overwhelming majority of the domestic chassis shell body in electrical control cabinet be all good aluminium alloy extrusions or
Galvanized steel plate.Metal chassis shell generally comprises cabinet main casing and rear panel, when installing connecting terminal, first locks plug
On plate below, jack assemblies are plugged together with pcb board and plug, are then locked plug and socket component with fastening screw, then
By in its integrally insertion cabinet main casing, finally rear panel is locked on cabinet main casing with fixed screw.In this way, pcb board
On earth current connect by the screw of pcb board with earth plate, then pass through earth plate and locking plug and jack assemblies
Fastening screw connection, and the latter connect with metal chassis shell.It, only need to be in any position of metal chassis shell when ground connection
Connect ground wire, so that it may the earth current of PCB and metal chassis shell be guided, realize the electrical safety being grounded jointly.Although
These metal chassis shells one can be grounded conduction, and two carry out good rigidity, can install the connecting terminal of some heavy duties, but golden
Belonging to chassis shell body also has at high cost, weight weight, the weakness for producing period length in enormous quantities.
A Plastic casing shell is devised at present referring to Fig. 1, when installing connecting terminal, is first locked plug 3' in plastics
On chassis shell body 1', jack assemblies 4' is packed into Plastic casing shell 1' with plug 3' with pcb board 2' with inserting later, can be complete
At installation.Referring to fig. 2 with inserting structure, cabinet is installed on Plastic casing shell 1' and is grounded interface column 5 ', on jack assemblies 4'
Socket mother is installed and sells 6', realizes that blindmate plugs together by the cooperation of the two parts, so that the earth current on pcb board 2' be passed through
The screw of pcb board 2', earth plate 7', socket mother sell 6', chassis earth line interface column 5', ground wire and guide, and realize common ground connection
Electrical safety.
By the comparison of installation steps, it can be found that the assembly of Plastic casing shell is simpler.But in structure, metal
Chassis shell body can be divided into rear panel and housing body, be fixed between the two parts by screw, so that plug and socket
Component can match to be plugged in advance is reloaded into metal chassis shell.And Plastic casing shell is because that itself should not make helicitic texture and not have
There are enough glue thickness for doing helicitic texture, if being made into split type, the integral rigidity of Plastic casing shell is just greatly reduced, this just makes
Plug, jack assemblies cannot in advance with being plugged, during installation can only first plug, then jack assemblies are installed again matched with plug
It inserts, in the process, because jack assemblies are all in Plastic casing shell, and Plastic casing shell is deep and narrow, also can not just see
See the process of jack assemblies insertion.
It practices and finds the Plastic casing shell scheme there is following deficiencies: 1. chassis earth line interface columns and socket
Mother's pin is high to concentricity requirement when with inserting, and jack assemblies are during blindmate, due to installing the presence in gap, it is difficult to ensure that its
It can be aligned and plug together；2. socket mother pin is screwed on the threaded hole of earth plate, cannot be well due to the limitation of structure space
It gives socket mother and sells the structure loosened, so socket mother pin inevitably shakes a little, this is tantamount to again during blindmate
Increase the difficulty that alignment plugs together.
Summary of the invention
