Description

A kind of shell and use the light fixture of this shell

Technical field

The utility model relates to electrical equipment, more particularly, and the lighting that relates to a kind of shell of electrical equipment and use this shell.

Background technology

Cable for electrical equipment is introduced, and Chinese patent CN87207002 discloses a kind of hermetically-sealed cable introducing device, as shown in Figure 1, comprises housing 1, outlet seat tube 2, outer-hexagonal plug screw joint 3, cushion block 4, sealing ring 5, spring washer 6 and hermetically-sealed cable 7.Outlet seat tube 2 is installed on the housing 1, and outer-hexagonal plug screw joint 3 is fixed on the hermetically-sealed cable 7, behind the lead-in cable, assembles each part successively, can introduce cable in the housing and is fixed on the housing.Though the cable entry of this structure has satisfied the requirement of fixing seal, have that spare and accessory parts are more, not good shortcoming of fixed effect of complex structure, manufacturing cost height, cable.

Explosion-proof lamp is strict with the internal structure and the material of light fixture, to reach the effect that seals flame proof fully, the present relevant regulations GB3836.2-2000 of China " explosive gas atmosphere electrical installation ", wherein part 2 the 12nd joint relates to the direct and introducing indirectly of the cable of electrical equipment, and the direct introducing encapsulating method of cable and the axial length of sealing etc. are claimed.The cable entry of existing explosion-proof lamp can satisfy the seal request of above-mentioned standard basically, but has the shortcoming that spare and accessory parts are more, the result is complicated and the cable fixed effect is not good equally.

Summary of the invention

Technical problem to be solved in the utility model is, introduces baroque defective at the cable of the above-mentioned electrical equipment of prior art, provides a kind of cable to introduce simple in structure, easy-to-install shell.

Another technical problem to be solved in the utility model is, introduces baroque defective at the above-mentioned lamp cable of prior art, provides a kind of cable that comprises to introduce light fixture simple in structure, easy-to-install shell.

The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of shell, on housing, be provided with cable and introduce the hole, described cable introduce the hole in described enclosure interior or/and the outside is provided with extension, described cable is introduced the hole or/and be provided with the casting glue of sealing between described extension and the described cable, is provided with the fastener of attached cable at the sidewall of described cable introducing hole or described extension.

Shell of the present utility model, described fastener are to be located in described cable to introduce housing screw on the sidewall of hole or extension.

Shell of the present utility model also is provided with one and promotes the compact heap that compresses by described housing screw between described housing screw and the described cable.

Shell of the present utility model, the contact-making surface of described compact heap and described cable are the plane or adapt to described cable profile phase.

Shell of the present utility model, described compact heap along the axial both sides of the edge of described cable towards described housing screw direction turnup.

Shell of the present utility model, the contact-making surface of described compact heap and described cable also is provided with sawtooth.

The technical scheme that another technical problem that solves the utility model adopts is: construct a kind of light fixture, comprise the shell in the technique scheme.

The beneficial effects of the utility model are, cable is set on shell introduces hole and extension, are different from existing cable entry, and are simple in structure, be easy to install, use the light fixture of this shell, not only simple in structure, be convenient to install, the cable good fixing effect has good sealing property simultaneously.

Description of drawings

The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:

Fig. 1 is the hermetically-sealed cable introducing device of prior art;

Fig. 2 is the schematic diagram of the utility model shell;

Fig. 3 is the profile of the utility model shell.

The specific embodiment

Shell of the present utility model as shown in Figure 2 to Figure 3, on housing 10, be provided with cable 11 and introduce hole 12, introduce hole 12 in described housing 10 inside at described cable 11, outside or the inside and outside extension 13 that is provided with simultaneously, the described extension 13 of present embodiment is located at the inside of housing 10, hole 12 introduced by cable 11 and extension 13 current supply cables 11 wear, cable 11 is introduced between hole 12 and extension 13 and the cable 11 has certain slit, penetrate the sealing of cable 11 usefulness casting glues 14, can satisfy GB3836.2-2000 " explosive gas atmosphere electrical installation " cable 11 length vertically the related request bonding casting glue 14 by the length that extension 13 is set.

Be provided with the housing screw 15 of attached cable 11 at the sidewall of described cable 11 introducing holes 12 or described extension 13, position at the corresponding housing screw 15 of sidewall also is provided with groove 17, be placed with compact heap 16 in the groove 17, compact heap 16 is located between cable 11 and the housing screw 15, screw housing screw 15 to cable 11 directions, under the effect of housing screw 15, compact heap 16 is pressed on the outline of cable 11.Described compact heap 16 can be the plane with the contact-making surface of described cable 11, also can adapt with described cable 11 outlines.Effect by compact heap 16, the application of force that the some active force of housing screw 15 is transferred to line or face, increased frictional force between compact heap 16 and cable 11 excircles, cable 11 is introduced in the hole 12 by the cable 11 that is fixed on tightly, limit cable 11 axial moving, thereby avoided the mobile casting glue that causes 14 of cable 11 to come unstuck, the packing less consequence of electrical equipment.

Described compact heap 16 can also be established sawtooth with the contact-making surface of described cable 11, and sawtooth is absorbed in the excircle of cable 11, has further strengthened the frictional force between compact heap 16 and the described cable 11.Described compact heap 16 along the axial two edges of described cable 11 towards described housing screw direction turnup, reduce the resistance of cable 11 turnover shells when installing, be convenient to moving axially of cable 11.

Shell of the present utility model can also be applied in the light fixture, explosion-proof lamp particularly, and cable 11 is introduced the sealing and fixing of part, can guarantee the sealing requirement of explosion of explosion-proof lamp.
