Abstract
The invention discloses a convenient and reliable cable entry. The convenient and reliable cable entry has the advantages that a steel block plate and a metal washer which can resist impact are arranged between a junction box and a connection joint, so that the impact resistance of the cable entry is improved largely, and the firmness of the cable entry is improved.
Description
?
Technical field
The present invention relates to electrical equipment, particularly, relate to a kind of convenient and reliable cable entry.
Background technology
Cable entry cable is introduced electric equipment and do not change the device of this equipment type of explosion proof construc tion, it is the transitional link that the electric wire of external circuit or cable enter electrical apparatus for explosive atmospheres, it is the important component part of explosion-proof electric equipment, but is also simultaneously the weakest part of electrical apparatus for explosive atmospheres.
The impact resistance of existing cable entry is not strong, usually occurs the phenomenons such as distortion because of washing away of external force, brings very large impact to the normal use of cable entry.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of convenient and reliable cable entry, this facilitates reliable cable entry to be provided with between terminal box and communicating joint can shock proof steel closure plate and metal washer, substantially increase the shock resistance of cable entry, improve the firmness of cable entry.
The present invention's adopted technical scheme that solves the problem is:
Convenient and reliable cable entry, comprise terminal box, platen, metal washer, steel closure plate, sealing ring and communicating joint, described terminal box is connected with communicating joint, steel closure plate and metal washer is provided with in communicating joint, described steel closure plate and metal washer fit together, also sealing ring is provided with between steel closure plate and terminal box, sealing ring and steel closure plate, terminal box, communicating joint are in contact, the right side of communicating joint is also connected to platen, the afterbody of described platen is horn-like, and the inside of platen is provided with smooth layer.
During enforcement, cable is accessed introducing device, due to the existence of steel closure plate and metal washer, the shock resistance of introducing device is greatly improved, the firmness of cable entry can be improved, improve the durability of cable entry to a certain extent.
Also comprise plug, described plug is arranged in the cavity of terminal box and communicating joint formation.
Described plug is also arranged with sealing ring sealing, and arranges the cylinder groove of multiple different radii in plug.The use amount that can reduce sealing ring on the one hand that arranges of plug reduces the bad probability generation of possible sealing property, there is provided straight-through passage to help cable location can on the other hand the cable of multiple different-diameter, introduce the needs of multiple cable can satisfy the demand simultaneously.The cylinder groove of multiple different radii just provides such convenience, in actual applications, can also be other difform channel-shaped structures, mainly determine according to the profile of cable.
With bolts between platen and communicating joint.Apply moment to bolt just platen and communicating joint to be compressed.
Described terminal box and communicating joint are die cast as one.
Described sealing ring is for adding ageing-resistant vulcanized rubber.Sealing ring is generally made up of rubber, in permanent use procedure, because the generation of the aging phenomenon of rubber, the elasticity of sealing ring can fade away and lose sealing function, and then affect the anti-explosion safety performance of electrical apparatus for explosive atmospheres, add the ageing properties that appropriate age resister can improve sealing ring to sealing ring, thus improve the usability performance of sealing ring.
To sum up, the invention has the beneficial effects as follows:
The present invention is provided with between terminal box and communicating joint can shock proof steel closure plate and metal washer, substantially increases the shock resistance of cable entry, improves the firmness of cable entry.
Accompanying drawing explanation
Fig. 1 is the structure chart of invention.
Mark and corresponding parts title in accompanying drawing:
1, terminal box, 2, sealing ring, 3, steel closure plate, 4, metal washer, 5, communicating joint, 6, bolt, 7, platen, 8, plug.
Embodiment
Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the present invention's do, but embodiments of the present invention are not limited thereto.
Embodiment 1:
As shown in Figure 1, convenient and reliable cable entry, comprise terminal box 1, platen 7, metal washer 4, steel closure plate 3, sealing ring 2 and communicating joint 5, described terminal box 1 is connected with communicating joint 5, steel closure plate 3 and metal washer 4 is provided with in communicating joint 5, described steel closure plate 3 and metal washer 4 fit together, sealing ring 2 is also provided with between steel closure plate 3 and terminal box 1, sealing ring 2 and steel closure plate 3, terminal box 1, communicating joint 5 is in contact, the right side of communicating joint 5 is also connected to platen 7, the afterbody of described platen 7 is horn-like, and the inside of platen 7 is provided with smooth layer.
During enforcement, cable is accessed introducing device, due to the existence of steel closure plate 3 and metal washer 4, the shock resistance of introducing device is greatly improved, the firmness of cable entry can be improved, improve the durability of cable entry to a certain extent.
Embodiment 2:
As shown in Figure 1, and embodiment 1 is similar, and difference is:
Also comprise plug 8, described plug 8 is arranged in the cavity of terminal box 1 and communicating joint 5 formation.
Described plug 8 is gone back and sealing ring 2 seals setting, and arranges the cylinder groove of multiple different radii in plug 8.The use amount that can reduce sealing ring 2 on the one hand that arranges of plug 8 reduces the bad probability generation of possible sealing property, there is provided straight-through passage to help cable location can on the other hand the cable of multiple different-diameter, introduce the needs of multiple cable can satisfy the demand simultaneously.The cylinder groove of multiple different radii just provides such convenience, in actual applications, can also be other difform channel-shaped structures, mainly determine according to the profile of cable.
Bolt 6 is adopted to connect between platen 7 and communicating joint 5.Apply moment to bolt 6 just platen 7 and communicating joint 5 to be compressed.
Described terminal box 1 and communicating joint 5 are die cast as one.
Described sealing ring 2 is for adding ageing-resistant vulcanized rubber.Sealing ring 2 is generally made up of rubber, in permanent use procedure, because the generation of the aging phenomenon of rubber, the elasticity of sealing ring 2 can fade away and lose sealing function, and then affect the anti-explosion safety performance of electrical apparatus for explosive atmospheres, add the ageing properties that appropriate age resister can improve sealing ring 2 to sealing ring 2, thus improve the usability performance of sealing ring 2.
As mentioned above, the present invention can be realized preferably.
