Description
Technical field
The present invention relates to fire-proof motor appurtenances technical field, and in particular to one kind meets with explosive gas ring
The explosion-proof type terminal box used in border.
Background technology
In the prior art, the terminal box for explosion-proof electric machine main power source, typically by using connection bolt and terminal sleeve
Flameproof joint is set, draws the requirement for reaching flame proof by coupling firmly, but terminal sleeve is on junction box seat in the structure
Fixed often caused composition surface is more, and explosion-proof effect is undesirable.And limited by terminal box cavity size, operating space
Small, manufacturability is poor.
The Chinese patent of Application No. 201610451424.9 discloses a kind of large space level Four explosion-proof connection box, the patent
Although application solves the problems, such as that traditional explosion-proof connection box inner space is narrow and small, it uses the conventional mode of connection i.e. terminal sleeve
It is enclosed on connection bolt, it is more to result in flameproof joint quantity, between junction box seat and terminal sleeve and stop washer, terminal sleeve
It is flameproof joint between connection bolt, flame proof effect is unsatisfactory.
The content of the invention
It is difficult for existing conventional anti-explosion terminal box wiring, the problem of flame proof effect is undesirable, it is an object of the invention to
A kind of explosion-proof type terminal box is provided, flameproof joint can be reduced, so as to improve explosion-proof effect.
In addition, narrow and small for existing conventional anti-explosion terminal box wiring space, it is a further object of the present invention to provide one kind
The explosion-proof type terminal box of wiring space can be increased, facilitate wiring.
The technical scheme is that:A kind of explosion-proof type terminal box, including junction box seat, on the junction box seat
The connector cover of side, the front end of terminal box are provided with the first explosion-proof screwed hole, and terminal box also includes explosion-proof installed in described first
Cable connector at screwed hole, the connection bolt on the junction box seat, it is provided with the connection bolt for solid
Determine the part of service cable, it is characterised in that:The junction box seat and the molding flitch being integrally formed is poured with it collectively form
One overall termination, the connection bolt pass through the overall termination.
The inner chamber of the terminal box is in large space square structure.
It is nut, plain cushion and spring washer that what is set on the connection bolt, which is used to fix the part of service cable,.
The second explosion-proof screwed hole is further opened with the junction box seat, be provided with the second explosion-proof screwed hole be used for and
When exclude condensed water drainage arrangement.
The drainage arrangement is explosion-proof breather drain valve.
The cable connector is explosion-proof Ge Lan heads.
Advantages of the present invention:The present invention by molding flitch is poured with junction box seat be integrally formed collectively form one it is whole
Body termination, connection bolt pass through the overall termination, in this way, for overall termination, flameproof joint
Exist only between molding flitch and connection bolt, set with terminal box in the prior art by using connection bolt and terminal sleeve
The method of flameproof joint is compared, and substantially reduces the quantity and area of flameproof joint, and explosion-proof effect is good.
In addition, the terminal box inner chamber of the present invention is in large space square structure, operating space is big, easy-to-connect;The present invention is also
Drainage arrangement is provided with, condensed water can be excluded in time, it is practical.
Brief description of the drawings
Fig. 1 is the general structure schematic diagram of the present invention;
Fig. 2 is Fig. 1 top view;
Fig. 3 is the partial enlarged drawing of flameproof joint between overall termination and connection bolt in Fig. 1.
In figure marked as:Junction box seat 1, connector cover 2, the first explosion-proof screwed hole 3, explosion-proof Ge Lan first 4, connection bolt 5,
Mold flitch 6, overall termination 7, the second explosion-proof screwed hole 8, explosion-proof breather drain valve 9.
Embodiment
As shown in figure 1, the invention mainly comprises junction box seat 1, the connector cover 2 above junction box seat 1, wiring
The front end of box is provided with the first explosion-proof screwed hole 3, and being provided with explosion-proof Ge Lan first 4 at the first explosion-proof screwed hole 3 is used as cable connector,
Terminal box inner chamber is in large space square structure, has larger cable rotary space, compared with conventional circular cavity terminal box, is increased
Big about 20-30% wiring space.
With reference to Fig. 2 and Fig. 3, junction box seat 1 and the molding flitch 6 being integrally formed is poured with it collectively form an entirety and connect
Line apparatus 7, terminal box also include the connection bolt 5 through overall termination 7, are provided with connection bolt 5 and are used for fixed
Nut, plain cushion and the spring washer of family cable, the second explosion-proof screwed hole 8 is further opened with junction box seat 1, is set according to GB3836 regulation
Corresponding flame proof thread length is put, the explosion-proof breather draining for excluding condensed water in time is provided with the second explosion-proof screwed hole 8
Valve 9, when motor in the larger place of humidity in use, the condensed water of junction box can be excluded effectively.
The terminal box of the present invention, by controlling flameproof joint, junction box seat 1 between junction box seat 1 and connector cover 2
The flame proof length of the flameproof joint between flameproof joint, connection bolt 5 and molding flitch 6 between explosion-proof Ge Lan first 4
And flame proof gap, reach explosion-proof effect, even if imflammable gas motor internally explodes, explosions are also not transferred to
Cause the blast of extraneous gas in the external world.Wherein, the flameproof joint of overall termination only includes connection bolt in terminal box
Composition surface between 5 and molding flitch 6, substantially reduces the area of flameproof joint, enhances explosion-proof effect.
All flameproof joints in the present invention use GB 3836.1-2000 standards.
The present invention is simple in construction, convenient and practical, and cost is low, less investment, easy-to-connect, and explosion-proof effect is good, practical.
Embodiment described above is only that the preferred embodiment of technical solution of the present invention is described, not to this hair
Bright scope is defined, and on the premise of design spirit of the present invention is not departed from, those of ordinary skill in the art are to the present invention's
The various modifications and improvement that technical scheme is made, it all should fall into the protection domain of claims of the present invention determination.
