Abstract
The utility model discloses a socket whose shell is a split type structure. The socket comprises the shell, a conductive pipe or a conductive rod which are arranged inside the shell, and an insulating device which is arranged between the shell and the conductive pipe or the conductive rod. The socket is characterized in that the shell comprises a housing of the socket and an internal lining ring which can be inserted into and by a plug. The part, which is inserted into and by the plug, of the housing is provided with a straight hole, and a step is formed by an internal hole of the housing and the straight hole. The internal lining ring is arranged inside the straight hole. The external surface of the internal lining ring is fit with the straight hole in an interference way. The beneficial effects of the socket are that the internal lining ring can select stainless copper or stainless steel material, the housing can adopt steel materials with low cost, and the internal lining ring and the housing are assembled together so that the socket shell is formed. The socket is low in cost, and surface of the part which is inserted into and by the plug is not rusted so that the socket is superior in overall performance, and damage to a flame-proof surface does not need to be worried.
Description
Technical field
The utility model relates to the socket of bolted flame-proof cable coupling device for mine, specifically relates to the socket that a kind of housing is split-type structural.
Background technology
Existing bolted flame-proof cable coupling device for mine, mainly by plug and socket two parts, formed, wherein the housing of socket is often the integral type structure, the person of ordinary skill in the field knows, can not there be the phenomenon of getting rusty on the surface that socket and plug divides interpolating unit, otherwise can't realize inserting, and destroy explosion suppresion surface.Socket casing for ferrous materials; often adopt at present electroplating technology at Socket casing Surface Creation one deck coating; get rusty avoiding; yet socket and plug divides and regular will carry out Plug Action interpolating unit; the surface of plug part that Here it is produces wearing and tearing; coating wears away rear plug surface and can not get protection, the destruction explosion suppresion surface that very easily gets rusty, thus whole socket is scrapped.Certainly, Socket casing also can adopt rustless copper material or stainless steel material, just can avoid the phenomenon of getting rusty, but copper material and stainless steel material cost ratio common iron are much higher, thereby production cost is too high.
Summary of the invention
For above-mentioned situation, the utility model provides the socket that a kind of housing is split-type structural, by in Socket casing, with plug, slotting position being arranged to inner bushing ring, only make inner bushing ring adopt rustless copper material or stainless steel material, the generation of the surface oxidisation phenomenon of avoiding socket and plug to divide interpolating unit, and production cost is not high.
To achieve these goals, the technical solution of the utility model is as follows:
The socket that a kind of housing is split-type structural, comprise contact tube in housing, housing or the seal between conducting rod and housing and contact tube or conducting rod; It is characterized in that, described housing comprises that the shell and of socket can realize slotting inner bushing ring with plug, described shell and plug to slotting part be provided with one with the straight hole of shell endoporus formation step, described inner bushing ring is arranged in this straight hole.
Wherein, between the outer surface of described inner bushing ring and straight hole be interference fit.
Described inner bushing ring is processed with chamfering near the outer corners of an end of step surface in shell.
The outer end of the straight hole of described shell is provided with the concave station of a circle and straight hole formation step, described inner bushing ring is corresponding with the concave station of shell, its end is provided with a circle boss, between the concave station end face of described shell and the raised head face of described inner bushing ring, is provided with a sealing ring.
The outer face of described inner bushing ring is not higher than the outer face of shell.
The beneficial effects of the utility model are, inner bushing ring can be selected rustless copper or stainless steel material, shell can adopt the ferrous materials that cost is low, both formation Socket casings that are assembled together, production cost is low, and do not have with the surface that plug divides interpolating unit the phenomenon of getting rusty, thereby the utility model overall performance is superior, needn't worries that explosion suppresion surface damages.
The accompanying drawing explanation
The structure cross-sectional schematic that Fig. 1 is a kind of housing of the utility model socket that is split-type structural.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the socket that a kind of housing is split-type structural, comprise contact tube in housing, housing or the seal 2 between conducting rod 1 and housing and contact tube or conducting rod.
Housing of the present utility model comprises shell 3 and the inner bushing ring 4 of socket, and described shell 3 and plug are provided with one to slotting part and form the straight hole of step with the shell endoporus, and described inner bushing ring 4 is arranged in this straight hole.The endoporus of described inner bushing ring 4 can be realized inserting with plug.
For inner bushing ring 4 and shell 3 are fixed as one reliably, between the straight hole of the outer surface of described inner bushing ring 4 and shell 3, adopt interference fit.
In straight hole for the ease of shell 3 that inner bushing ring 4 is packed into, described inner bushing ring 4 is processed with chamfering near the outer corners of an end of shell 3 interior step surfaces.
For the ease of inner bushing ring 4, in the straight hole of shell 3, be in place, and realize the sealing between inner bushing ring 4 and shell 3, be provided with the concave station that a circle and straight hole form step in the outer end of the straight hole of described shell 3, described inner bushing ring 4 is corresponding with the concave station of shell 3, its end is provided with a circle boss, between the concave station end face of described shell and the raised head face of described inner bushing ring, is provided with a sealing ring 5.When assembling, the concave station end face press seal circle 5 of the raised head face of inner bushing ring 4 and shell 3, inner bushing ring 4 completes with the assembling of shell 3.
For socket and plug is assembled together reliably, the outer face of described inner bushing ring 4 should be not higher than the outer face of shell 3.
Housing of the present utility model is because being split-type structural, so inner bushing ring 4 can be selected rustless copper or stainless steel material, shell 3 can adopt the ferrous materials that cost is low, both formation Socket casings that are assembled together, production cost is low, and do not have with the surface that plug divides interpolating unit the phenomenon of getting rusty, thereby the utility model overall performance is superior, needn't worries that explosion suppresion surface damages.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and specification, describe is principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection range that the utility model requires is defined by appending claims and equivalent thereof.
