Abstract
The utility model discloses an anti-explosion straight-insert joint, which is characterized in that a contact elastic sheet is fixed on a socket body through an elastic fastening plate and fastening plate fixing nuts, one end of the contact elastic sheet is arranged inside a socket cavity, and an end face of the other end of the contact elastic sheet is arranged on an end face of the socket body correspondingly. A plug comprises a plug body and a contactor, wherein the plug body is arranged in a plug cavity, and the contactor is matched with the contact elastic sheet. The contactor is fixed on the plug body through a contactor fastening plate and the fastening plate fixing nuts, one end of the contactor is arranged inside the plug cavity, and the other end of the contactor is lower than an end face of the plug body. As the contact elastic sheet is arranged on an end face of the plug body, and one end of the contactor is lower than the end face of the plug body, when the anti-explosion straight-insert joint is inserted, air outside the socket body and the plug body is separated from air inside the same after the socket body and the plug body are matched and fixed, and when the contactor is communicated with the contact elastic sheet, electric sparks can be limited within a limited space, and thereby the anti-explosion purpose is achieved.

Background technology
Also be not specially adapted for the electric power connecting device of explosion-proof industrial vehicle now on the market, and the complex structure of general anti-explosion cable jockey, the technological requirement height, involve great expense, be not suitable for small lot batch manufacture, the insulation of its internal structure is mainly plastics or rubber material, and needs molding; The explosion-proof face of this electric power connecting device is mainly screw thread and is torqued into formula simultaneously, inconvenience during its assembling, long electric spark or the electric arc of being easy to generate of grafting time.
The utility model content
The technical problem that the utility model mainly solves provides a kind of explosion-proof straight cutting joint, and this explosion-proof straight cutting joint design is simple, easy to assembly, and power on/off time while is shorter, is not easy to produce electric spark or electric arc, and explosion-proof effect is good.
In order to address the above problem, the utility model provides a kind of explosion-proof straight cutting joint, this explosion-proof straight cutting joint comprises the plug and socket that cooperatively interacts, described socket comprises jack body and the contact flat spring that is provided with socket cavity, this contact flat spring is fixed by shell fragment clamp and clamp hold-doun nut and jack body, and the one end is arranged in the described socket cavity, and the end face of the other end is positioned at corresponding jack body end face; Described plug comprises header body that the plug cavity is set and the contact head that cooperates with contact flat spring, this contact head is fixed by contact head clamp and clamp hold-doun nut and header body, this contacts first end and is positioned at the plug cavity, the other end is lower than this header body end face, and described header body and jack body closely cooperate.
Preferably, described contact flat spring is provided with retainer plate.
Preferably, described contact head is cross.
Preferably, between described jack body and the shell fragment clamp, be respectively equipped with insulating pad between described header body and the contact head.
Preferably, described explosion-proof straight cutting joint also comprises limit screw, and this limit screw cooperates fixing with jack body and header body.
The explosion-proof straight cutting joint of the utility model, described contact flat spring is fixed by shell fragment clamp and clamp hold-doun nut and jack body, and the one end is arranged in the described socket cavity, and the end face of the other end is positioned at corresponding jack body end face; Described plug comprises header body that the plug cavity is set and the contact head that cooperates with contact flat spring, this contact head is fixed by contact head clamp and clamp hold-doun nut and header body, this contacts first end and is positioned at the plug cavity, the other end is lower than this header body end face, and described header body and jack body closely cooperate.Because described contact flat spring is positioned at the jack body end face, the first end of described contact is lower than this header body end face, when patching, described jack body cooperates earlier fixing with after air outside jack body and the header body and the blocking-up of its inner air with header body, when described contact head is connected conducting with contact flat spring,, thereby reach explosion-proof even produce also being limited in the confined space of electric spark, this explosion-proof straight cutting joint design is simple, easy to assembly.Because explosion-proof straight cutting joint is to fix by jack body and header body inserting mode, can directly insert quick realization break-make power supply, so the power on/off time is shorter, is not easy to produce electric spark or electric arc, and then reaches better explosion-proof effect simultaneously.

The explanation of Figure of description critical piece
Socket 1 '; Plug 2 '; Jack body 1; Header body 2; Fixed cover 3; Cable 4;
Below in conjunction with embodiment, and with reference to accompanying drawing, realization, functional characteristics and the advantage of the utility model purpose is described further.
Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model provides a kind of explosion-proof straight cutting joint embodiment.
Described explosion-proof straight cutting joint comprises: the plug 2 that cooperatively interacts ' and socket 1 ', described socket 1 ' the comprise jack body 1 and the contact flat spring 13 that are provided with socket cavity 11, this contact flat spring 13 is fixing with jack body 1 by shell fragment clamp 15 and clamp hold-doun nut 18, and these contact flat spring 13 1 ends are arranged in the described socket cavity 11, and the end face of the other end is positioned at corresponding jack body 1 end face; Described plug 2 ' comprise header body 2 that plug cavity 21 is set and the contact head 22 that cooperates with contact flat spring 13, this contact head 22 is fixing with header body 2 by contact head clamp 23 and clamp hold-doun nut 18, these contact head 22 1 ends are positioned at plug cavity 21, the other end is lower than this header body 2 end faces, and described header body 2 closely cooperates with jack body 1.
Specifically, described contact flat spring 13 1 end faces are positioned at jack body 1 end face, the other end be arranged on socket cavity 11 in be connected with cable; Described contact head 22 is fixing with header body 2, and the one end is positioned at header body 2, and the other end is arranged in the plug cavity 21 and with cable 4 and is connected, and this cable 4 is fixing with header body 2 by fixed cover 3.
When explosion-proof straight cutting joint patches, because described contact flat spring 13 is positioned at jack body 1 end face, described contact head 22 1 ends are lower than this header body 2 end faces, described jack body 1 cooperates earlier with header body 2 to be fixed, after air outside jack body 1 and the header body 2 and the blocking-up of its inner air, when described contact head 22 is connected conducting with contact flat spring 13, even also being limited in the confined space of generation electric spark, thereby reach explosion-proof, this explosion-proof straight cutting joint design is simple, easy to assembly.Because explosion-proof straight cutting joint is to fix by jack body 1 and header body 2 inserting mode, can directly insert quick realization break-make power supply, so the power on/off time is shorter, is not easy to produce electric spark or electric arc, and then reaches better explosion-proof effect.
