Abstract
The invention relates to a power source connector. The power source connector comprises an insulation base, a contact, a covering plate, a positioning plate and a positioning claw, wherein a supporting structure integrated with the covering plate is arranged on the covering plate, and the supporting structure is located between the insulation base and the covering plate after assembly is finished. The power source connector overcomes the defects that a common electric connector moves easily and a copper alloy punching supporting part is damaged in the circulation or assembly process, avoids the complexity when the common electric connector is assembled, even omits one part, reduces investment of moulds, reduces cost, and overcomes the defect that safety risks exist due to the fact that a traditional metal supporting sleeve generates point discharge easily.
Description
Technical field
The invention belongs to the power connector in communication apparatus, industrial equipment, urban track traffic and rolling stock field.
Background technology
Traditional electrical connector construction mainly exists following shortcoming with not enough:
One, in traditional electrical connector, support fixed position and be generally copper alloy punching part, copper alloy punching part can be realized its function preferably, but but has some defects:
1. copper alloy punching support part is arranged on contact, easily damaged in the process of transportation or the order of changing a job;
2. in the more situation of core number, easily neglected loading in assembling process, and process is loaded down with trivial details inefficent.
3. because copper alloy support part needs and contact combination is rear, use, enough gaps need be left in insulating base inside, cause like this contact rolling momentum very large, to inserting easy injuring part.
4. there is many places cusp in copper alloy punching support part, and in high voltage or moment, overload in the situation that, the electric discharge that easily tapers off to a point, causes insulating base breakdown, makes electric connector inefficacy, has hidden danger.
Two, its contact length of general electric connector is consistent, not by the first conducting of the contact of earthing position, in high-voltage great-current situation, easily produces dangerous.
Summary of the invention
The invention provides a kind of Novel support structure, in the hope of improving the shortcoming of traditional copper alloy punching support part.
For achieving the above object, the present invention is by the following technical solutions:
A power connector, comprises insulating base, contact, cover plate, location-plate, locating detent five parts, has the supporting construction into a single integrated structure with cover plate on described cover plate, has assembled rear support structure between insulating base and cover plate.
Described insulating base is mould of plastics moulding, has anti-error tankage on it, has circular port on it;
Described cover plate includes supporting construction and buckle lock structure, and supporting construction is taper, is divided into symmetrical two, and padlock is back-off structure;
Described contact is car workpieces, and material is copper alloy, by insulating base and cover plate, fix, and be the core conductive pieces of electric connector, can pass through hand assembled, and dismantle with specific purpose tool;
The first conducting of the described contact of earthing position is increased, in high-voltage great-current situation, when the phase line that certain reason causes (as bad in wire insulation, aging circuit etc.) and when device housings touches, the shell of equipment will produce by dangerous voltage, and the fault current generating thus will be flowed through PE line to the earth;
The groove of described insulating base and the buckle lock structure of described cover plate can fasten and be integrated, and with this, contact are fixed;
The circular port of described insulating base can be mutually nested with the circular port of described cover plate, with this, contact is circumferentially fixing;
Described supporting construction, after assembling completes, the annular groove that the small end of its back taper blocks contact can be realized fixing, also can be strutted with specific purpose tool, with this, dismantles contact.
Can reach following technique effect thus:
One, the optimization improvement for electric connector supporting construction is: strutting piece is changed into supporting construction and cover plate are made into one by traditional copper alloy punching part, assembled rear support structure between insulating base and cover plate.
The play that this scheme had both avoided general electric connector to be prone to, in circulation or assembling process, damage the shortcoming of copper alloy punching support part, avoided again the loaded down with trivial details of general electric connector assembling, even reduced by a part, the input that has reduced mould, has reduced cost; Be exactly that the metallic support of having avoided traditional is overlapped the electric discharge that easily tapers off to a point in addition, have the defect of potential safety hazard.
Two, the contact of earthing position is increased to (first conducting); in high-voltage great-current situation; when the phase line that certain reason causes (as bad in wire insulation; aging circuit etc.) and when device housings touches; the shell of equipment will produce by dangerous voltage; the fault current generating thus will be flowed through PE line to the earth, thereby play a protective role, avoids producing danger.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
As shown in Figure 1, a kind of power connector, comprises insulating base 1, contact, cover plate 2, location-plate 3, locating detent 7 five parts.Contact comprises that long contact pin 4, high contact pin 5, short contact pin 6 are several.
Described insulating base 1 is mould of plastics moulding, has anti-error tankage on it, has circular port on it;
Described cover plate 2 includes supporting construction and buckle lock structure, and supporting construction is taper, is divided into symmetrical two, and padlock is back-off structure;
Described contact is car workpieces, and material is copper alloy, by insulating base and cover plate, fix, and be the core conductive pieces of electric connector, can pass through hand assembled, and dismantle with specific purpose tool;
The described contact of earthing position is increased to first conducting, in high-voltage great-current situation, when the phase line that certain reason causes (as bad in wire insulation, aging circuit etc.) and when device housings touches, the shell of equipment will produce by dangerous voltage, and the fault current generating thus will be flowed through PE line to the earth;
The groove of described insulating base and the buckle lock structure of described cover plate can fasten and be integrated, and with this, contact are fixed;
The circular port of described insulating base can be mutually nested with the circular port of described cover plate, with this, contact is circumferentially fixing;
Described supporting construction, after assembling completes, the annular groove that the small end of its back taper blocks contact can be realized fixing, also can be strutted with specific purpose tool, with this, dismantles contact.
In addition, long contact pin also can change long earth jack 24 into, only need to change the socket of power connector into the plug supporting with jack 21, and plug 21 also has supporting with it cover plate 22.
