The utility model relates to an explosion insulation plug connector for mine usage, which is that the top of a wiring terminal which is connected with one end of load is designed into a complete plane surface on the basis of the existing connector; the diameter of the plane surface is best between phi 28 mm to 32 mm; a circlip for hole is arranged in the annular groove which is arranged in a socket casing which faces to one side of a movable contact; the gasket used by the screw bolt of a wiring terminal which is connected with the movable contact is a pi shaped lock washer with double ears; besides, a plug casing is provided with two positioning lugs. The utility model has the advantages that the explosion insulation plug connector for mine usage can make that the vulnerability of fuses is reduced more than 50%; service life is prolonged; human power and material resource consumption is reduced; the utility model can be used safely.
Description
The utility model relates to a kind of connector that is used on the electric car.
Existing be used for the mining flame-proof latch connector on the battery locomotive under the coal mine, can be used as the electric equipment that connects or disconnect electric locomotive under the no-load situation, and main circuit of electric locomotive is done overload protection and short-circuit protection by the interior fuse of establishing.The structure of this connector is that fuse one end of establishing in the jack housing can link to each other with the load outside the socket end cap by binding post that is with spring and the line terminals that is fixed thereon, spring one end that is positioned at the binding post peripheral hardware that moving contact connected that the plug body that flexibly connects with jack housing can join with the fuse other end is against on this moving contact, the other end places in the insulating case, be fixed on and be positioned at socket-head cap with the line terminals that power supply joins on this binding post, on jack housing, also be fixed with turnover plate type pinned coupler dust cap in addition.Its weak point is that overload capacity is poor, the life-span short, changes the fuse inconvenience.
In view of above-mentioned weak point the purpose of this utility model of the prior art is to provide that a kind of current capacity is big, long service life, replacing fuse pinned coupler easily.
The purpose of this utility model can realize by following measure: a kind of mining flame-proof latch connector that is used in the electric locomotive, it is that fuse one end of establishing in jack housing can link to each other with the load outside the socket end cap by binding post that is with spring and the line terminals that is fixed thereon, spring one end that is positioned at the binding post peripheral hardware that moving contact connected that the plug body that flexibly connects with jack housing can join with the fuse other end is against on this moving contact, the other end places in the insulating case, be fixed on and be positioned at socket-head cap with the line terminals that power supply joins on this binding post, also be fixed with turnover plate type pinned coupler dust cap in addition on jack housing, it is characterized in that: the binding post top that links to each other with load one end is complete plane.Preferably the diameter on this plane is between φ 28～32mm.In the set annular groove of the jack housing inwall on the insulating case top that can match, be provided with circlip for hole with fuse one end that moving contact joins, the packing ring used with the bolt on the binding post that moving contact links to each other is π shape lock washer with double ears, be provided with on the plug body two with the locomotive plug boot on two projections that reference column is complementary.
The utility model mainly is to improve on the basis of original mining flame-proof latch connector, at first be to be provided with diameter another cylinder greater than this cylinder in the side that the binding post middle part that socket part links to each other with load one end is connected as a single entity with it for cylinder, the boss that intersects by both can carry out whole binding post spacing, the top of this major diameter cylinder is a complete plane, and diameter is between φ 28～32mm, so not only increase the contact area between binding post and the fuse, thereby reduce surface contacted resistance and reduce fuse surface heat amount, improve conduction and current capacity, also guaranteed the minimum electric clearance of explosion-proof electric apparatus simultaneously, the cuboid of this binding post opposite side for being connected as a single entity with it, can be provided with the bolt of the static line terminal and the lead that links to each other with load end in its through hole, preferably silver-plated processing is carried out on this binding post surface, prevent that its surface is subjected to thermal oxidation to increase resistance, at safety fuse one end that can join with moving contact, be provided with circlip for hole in the set annular groove of the jack housing inwall on the insulating case top that matches, it can carry out spacing to fuse by insulating case, can load and unload easily again, provide convenience for changing fuse.Flexible conductor in plug portion is fixed on moving contact is to link to each other by bolt with its binding post, and its used packing ring is preferably π shape lock washer with double ears, and it can all be included in lead interior and compress to reduce resistance and increase conductive capability.On plug body, be provided with in addition two with the locomotive plug boot on the projection that is complementary of two reference columns or in the projection that parallels strip groove with axis is arranged, prevent to produce transposition because of the locomotive vibration connector.
Improved its conductive capability and current capacity by above-mentioned improvement, the fragile rate of fuse is reduced more than 50%, improved useful life, reduced because of changing the man power and material that fuse brought consuming the connector internal structure.And use more safe and reliable to the improvement of connector external structure.
Drawing is described as follows:
Fig. 1 is that master of the present utility model looks generalized section.
Fig. 2 is a binding post front elevational schematic of the present utility model.
Fig. 3 is a binding post schematic top plan view of the present utility model.
Fig. 4 is that the master of π shape lock washer with double ears of the present utility model looks generalized section.
Fig. 5 is a plug body schematic top plan view of the present utility model.
The utility model is described in further detail to utilize the example shown in the accompanying drawing.Master at mining flame-proof latch connector shown in Figure 1 looks in the generalized section, this connector sub-plug and socket two parts, they flexibly connect by staged cotter way and pin key, and socket is by forming by bolted jack housing 1 and socket end cap 2.Fuse 3 one ends of establishing in the jack housing can link to each other with the load outside the socket end cap by binding post 5 that is with spring 4 and the line terminals 6 that is fixed thereon, in the binding post schematic diagram of Fig. 2 and flame proof pinned coupler shown in Figure 3, the middle part of binding post is a cylinder, the one side is that the top is the cylinder on complete plane, and its opposite side is the cuboid that is provided with through hole.Again in Fig. 1, in the set annular groove of the jack housing inwall on insulating case 8 tops that fuse can match with the end that moving contact 7 joins, be provided with circlip for hole 9.The moving contact that is positioned at plug body 18 links to each other with binding post 10 by flexible conductor, its used packing ring be π shape ears packing ring 11 as shown in Figure 4.Spring 12 1 ends of the binding post peripheral hardware that is connected with moving contact are against on this moving contact, and the other end places in the insulating case 13.Be fixed on and be positioned at socket-head cap 15 with the line terminals 14 that power supply joins on this binding post.On jack housing, also be fixed with turnover plate type pinned coupler dust cap 16 in addition.Again in Fig. 1 and Fig. 5, plug body be provided with two with the locomotive plug boot on the projection 17 that is complementary of two reference columns.Brass or the fine copper that it is good that metalwork in this connector shell adopts conduction are made, and silver-plated processing is carried out on the surface.
