Description

The anti-open circuit of a kind of current circuit connector
Technical field
The utility model relates to power system automatic field, is specifically related to the anti-open circuit of a kind of current circuit connector.
Background technology
In the electric power system distribution automation implementation process, need current signal be received the distribution power automation terminal device through connector from a switchgear.In the traditional design; The current signal of delivering to the distribution terminal from switch all is to adopt common connector to connect, and when needs maintenance or replacing distribution terminal, needs just carrying out after this line outage; Otherwise during the open circuit of the CT secondary side in being connected on electrical network; Can respond to very high open circuit voltage, cause accidents such as loss of life or personal injury, device damage, have a strong impact on the normal operation of electrical network.
Practical content
The utility model technical problem to be solved is: the anti-open circuit of a kind of current circuit connector is provided.Use it under situation about not having a power failure, to overhaul or change distribution terminal, can prevent that instrument transformer from burning or explode, and needs the defective with this line outage when using existing distribution automation end product maintenance or changing distribution terminal to overcome.
In order to solve this technical problem, the utility model adopts following technical scheme:
The anti-open circuit of a kind of current circuit connector comprises plug and socket; Said plug comprises: plug casing, be filled in insulator A, the contact pin of plug bottom; Said socket comprises: the jack that is filled in the insulator B of socket bottom, is complementary with contact pin; It is characterized in that: said plug also comprises: around the insulating case of plug casing inwall be applied in the anti-open circuit plate on the contact pin, said anti-open circuit plate is connected on the insulator A through stage clip; Shape and the plug of said socket insulator B are complementary.
Said plug is preferably four pins or six pins; The socket that is complementary is four holes or six holes.
The good effect of the utility model is:
Use the utility model connector; Owing to there is an anti-open circuit plate on the plug; When plug did not insert socket, this anti-open circuit plate adopted insulating case and casing insulation to realize anti-open circuit of electric current and requirement of withstand voltage with the whole contact short circuits in the plug together simultaneously.
When connector plugged together, under the pushing effect of the insulator on the socket, stage clip was compressed, and anti-open circuit plate produces corresponding displacement.After socket advances a segment distance, anti-open circuit plate begin with plug on contact pin break off, jack begins contact insert pin simultaneously.Plug continues to insert socket, and after the anti-open circuit plate on the plug was shifted onto ad-hoc location by the insulator on the socket, contact pin contacted with jack fully, thereby and anti-open circuit plate and the anti-open-circuit condition of contact pin releasing are realized normal signal transmission.In like manner, when the needs disconnect connector, process is opposite.Since plug and the socket of pairing separate with insertion process in an anti-function of open and signal transfer functions overlay region are arranged, can guarantee plug instantaneous open circuit of unlikely generation in the plug process.
Plug is four pins or six pins, and socket is four holes or six holes, makes four-core or six core connectors, can satisfy the two meter technique or the genuine standard sampling of a switch.
Use the utility model connector can under situation about not having a power failure, overhaul or change distribution terminal; Prevent that instrument transformer from burning or explode, having overcome needs the defective with this line outage when using existing distribution automation end product maintenance or changing distribution terminal.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Like Fig. 1, Fig. 2, shown in Figure 3, the anti-open circuit of a kind of current circuit connector comprises plug 1 and socket 2; Said plug 1 comprises: plug casing 1-5, the insulator A1-6 that is filled in the plug bottom, plain cushion 1-7, back-up ring A1-8, pad 1-9, crimp ring 1-10, card cap 1-3, contact pin 1-1; Said socket 2 comprises: Socket casing 2-6, the insulator B2-5 that is filled in socket bottom, sealing ring 2-2, plain cushion B2-4, the bayonet lock 2-3 that is complementary with the card cap, the jack 2-1 that is complementary with contact pin; Said plug 1 also comprises: around the insulating case 1-11 of plug casing 1-5 inwall be applied in the anti-open circuit plate 1-2 on the contact pin 1-1, said anti-open circuit plate 1-2 is connected on the insulator A1-6 of plug bottom through stage clip 1-4; Shape and the plug 1 of said socket 2 insulator B2-5 are complementary.
Said plug is preferably four pins or six pins; The socket that is complementary is four holes or six holes.
Use the utility model connector; Owing to there is an anti-open circuit plate 1-2 on the plug 1; When plug 1 does not insert socket 2; Should anti-ly open a way plate 1-2 together, and adopt insulating case 1-11 and plug body 1-5 insulation simultaneously to realize anti-open circuit of electric current and requirement of withstand voltage with the whole contact short circuits in the plug.
When connector plugged together, under the pushing effect of the insulator 2-5 on the socket 2, stage clip 1-4 was compressed, and anti-open circuit plate 1-2 produces corresponding displacement.After plug 1 advances a segment distance, anti-open circuit plate 1-2 begin with plug 1 on contact pin 1-1 break off, jack 2-1 begins contact insert pin 1-1 simultaneously.Plug 1 continues to insert socket 2, and after the anti-open circuit plate 1-2 on the plug 1 was shifted onto ad-hoc location by the insulator 2-5 on the socket 2, contact pin 1-1 contacted with jack 2-1 fully, thereby and anti-open circuit plate 1-2 and the anti-open-circuit condition of contact pin 1-1 releasing are realized normal signal transmission.In like manner, when the needs disconnect connector, process is opposite.Since plug 1 and socket 2 separate with insertion process in an anti-function of open and signal transfer functions overlay region are arranged, then can guarantee the instantaneous open circuit of unlikely generation in the plug process.
Plug 1 is four pins or six pins, and socket 2 is four holes or six holes, makes 4 cores or 6 core connectors, can satisfy the two meter technique or the genuine standard sampling of a switch.
Use the utility model connector can under situation about not having a power failure, overhaul or change distribution terminal; Prevent that instrument transformer from burning or explode, having overcome needs the defective with this line outage when using existing distribution automation end product maintenance or changing distribution terminal.
