The connector comprises a contactor and a positioner, the positioner is an arc-shaped column, the contactor is a similar prism structure, one side of the contactor is level with a section of the arc-shaped column, both the other two sides of the contactor are curved surfaces, an arc-shaped groove is arranged on the upper surface of the positioner, the press plate is also an arc-shaped column, a groove which corresponds to an arc-shaped groove on the upper surface of the positioner is arranged on the surface of the press plate, and the press plate is connected with the positioner via a bolt. The contact area of the connector is large, convenience and reliability in connection are realized, and accordingly the high-current connecting device is particularly suitable for 20A-100A high-current connection.
Description
Technical field
The utility model relates on a kind of and the machine big electric current and safeguards the big current connection apparatus that socket is connected.
Background technology
When using the aviation ground checkout equipment that aeroplane performance is checked; Need be the ground checkout equipment power supply usually through the on-board maintenance supply socket; Safeguard that supply socket generally is divided into exchanging and safeguard that socket and direct current safeguard two types of sockets that direct current safeguards that socket can be divided into by the maximum load current that can pass through that medium and small electric current is safeguarded socket, electric current safeguards that socket and especially big electric current safeguard socket greatly.Medium and small electric current safeguards that socket usually selects CX-series aboard for use or meet two core sealed electrical connectors of the band installing hole that GJB599A requires; Especially big electric current is safeguarded the connection when socket generally is used for the ground power supply car to aviation power supply more, usually selects PJ-series electric connector for use; For big electric current socket; Big electric current has been installed on China's type aircraft shown in accompanying drawing 1 has been safeguarded socket, it is for having two-layer split ring chip architecture, and its internal layer spring leaf is plane and curved surface structure combining; At present when using this socket; Two cylindrical copper rods that have lead-in wire are inserted in two semicircle grooves in the socket outside, and each connects with bolt up and down then, connects reliable but uses inconvenient.
Summary of the invention
To the deficiency of the cylindrical copper rod insertion of present use socket, the utility model proposition is a kind of can to make things convenient for the big current connection apparatus that is connected with socket.
The technical scheme that the utility model is taked is: a kind of big current connection apparatus, comprise connector and compressing tablet, and connector comprises contact and positioning body; Positioning body is the circular arc cylinder; The triangular shape structure of contact type of being, it is concordant with the tangent plane of circular arc cylinder on one side, and the other both sides of contact are curved surface; The positioning body upper surface has an arc groove; Compressing tablet also is the circular arc cylinder, and its surface is provided with a corresponding groove of the arc groove with the positioning body upper surface, and compressing tablet is connected through bolt with positioning body.
Further, for better implement the utility model, contact is wedge structure on the axis direction of positioning body.
Further, the draft angle of above-mentioned contact is between 2 °～3 °.
Further, connector 1, the compressing tablet 2 to machine-shaping carries out the surface gold-plating processing.
The utility model beneficial effect: the connector contact area is big, and is easy to connect, firm, is particularly suitable for connecting through the electric current of 20A～100A.
Description of drawings
Fig. 1 (a) (b) safeguards socket front view and end view for the big electric current of certain type aircraft;
Fig. 2 (a) is big current connection apparatus front view and end view (b), wherein 1: connector, 2: compressing tablet.
Embodiment
The utility model is described further with the explanation accompanying drawing below in conjunction with embodiment.
See also Figure of description 2, it is the utility model one preferred embodiments.
A kind of big current connection apparatus comprises connector 1 and compressing tablet 2, and connector 1 comprises contact 11 and positioning body 12; Positioning body 12 is the circular arc cylinder, the triangular shape structure of contact 11 types of being, and it is concordant with the tangent plane of positioning body 12 on one side; The other both sides of contact 11 are curved surface, and positioning body 12 upper surfaces have an arc groove 13, and compressing tablet 2 is the circular arc cylinder corresponding with positioning body 12; Its surface is provided with the arc groove 13 corresponding grooves 21 with positioning body 12 upper surfaces; Compressing tablet 2 and positioning body 1 are connected through bolt, and Φ 4mm screw is arranged on the connector 1, and corresponding positions is equipped with the through hole of Φ 4mm on the compressing tablet 2; Connect with the M4 counter-sunk screw after adding upper conductor between compressing tablet and the connector, select suitable screw length, make head of screw concordant with connector screw lower surface.
Further, as an optimal way of present embodiment, contact 11 is wedge structure on the axis direction of positioning body 1.
Further, the draft angle of above-mentioned contact adopts 2 °～3 ° draft angle to help pegging graft between 2 °～3 °, utilizes the tension force of sheet metal on the socket to guarantee excellent contact between connector 1 and the socket.
Contact 11 two side curve forms and socket inwall curve form are identical, and smooth surface, to guarantee that maximum contact area is arranged.
During work,, and bare wire is pressed in the arc groove 13 of connector 1 the line skin of peelling off lead termination suitable length, and fixing with compressing tablet 2.
For guaranteeing abundant contact, about contact 11 height and the big 3mm of the socket degree of depth; Arc groove 21 width of the upper surface of connector are identical with the line of folded lead footpath; More shallow on the compressing tablet 2 with arc groove 13 corresponding groove 21 depth ratio arc grooves 13, so that compress lead.
For better implement the utility model, increase the electric conductivity of jockey, connector 1, the compressing tablet 2 of machine-shaping carried out surface gold-plating handle.
The connector contact area is big, and is easy to connect, firm, is particularly suitable for connecting through the electric current of 20A～100A.
