Description

Adaper plug earth terminal slip location structure

[technical field]

The utility model relates to adaper plug, specifically relates to the improvement of adaper plug earth terminal slip location structure.

[background technology]

Existing adapter is owing to limited by the safety dimensional requirement, and particularly the 3-phase plug partial volume is bigger to cause adapter, and manufacturer packs, the transportation requisite space is excessive, causes the material waste, and cost increases, and is unfavorable for environmental protection.

Tradition slip location structure normally utilizes shell fragment or spring and realizes cooperating of sliding shoe, this structure needs the part combination more than three or three to finish assembling, the utility model collects two kinds of materials in a part (i.e. twice moulding), replace shell fragment or spring, the design feature of utilization own has just realized this performance requirement fully.

[utility model content]

The utility model provide a kind of easy to use, make the slide adaper plug of location of simple earth terminal, reach the purpose of this utility model by following measure:

This adaper plug earth terminal slip location structure, it is characterized in that: comprise housing, earth terminal and cover, wherein earth terminal is L-shaped, comprise Plug Division and vertical with it sliding part, cover is fixed on the housing sliding part slip is defined in the housing, be provided with the slip stopping means that cooperatively interacts between sliding part and housing, be provided with the positioner that cooperatively interacts between sliding part and cover.

The slip stopping means comprises the projection that the sliding part bottom of being located at earth terminal is outside and the chute of corresponding shell upper edge earth terminal glide direction with it.

Positioner comprises strip projected parts above the sliding part of being located at earth terminal and the projection on the corresponding with it cover bottom surface.

Cover is fixedlyed connected with housing by screw.

The sliding part of earth terminal comprise sliding outer cover and be fixedly connected in the sliding outer cover and with the integrated connecting portion in Plug Division, the projection of slip stopping means and the strip projected parts of positioner are located at the corresponding position of sliding outer cover.

Sliding outer cover is made by plastics wear-resisting and that have a plastic deformation, and Plug Division and integrated with it connecting portion are made by the plastic-steel material.

The junction of Plug Division and connecting portion forms a neck that concaves.

Usefulness of the present utility model is: utilize earth terminal and cover self structure to cooperate, realize the slip positioning function, thereby reduced Assembly part, to reduce cost; Because product is having higher requirement aspect intensity and the resistance to wear, same plastic material is difficult to meet the demands, so the earth terminal of the utility model adopts moulding process twice, utilizes the characteristic of different plastic cement to realize product performance demands.

[embodiment]

The utility model is further described with embodiment below in conjunction with accompanying drawing:

As shown in Figure 1, this adaper plug earth terminal slip location structure comprises housing 10, cover 20 and earth terminal 30, is fixed with other 2 pins 11 on the housing 10, and cover 20 is fixed on earth terminal 30 in the housing 10 slidably by screw 21.Two states when Fig. 2 and Fig. 3 can react this plug work and inoperative.Earth terminal 30 is L-shaped, comprises Plug Division 31 and vertical with it sliding

part

32, and 10 of sliding part 32 and housings are provided with the slip stopping means that cooperatively interacts, and 20 of sliding part 32 and covers are provided with the positioner that cooperatively interacts.Simultaneously referring to Fig. 4, Fig. 7, the slip stopping means comprises the projection 33 that sliding part 32 bottoms of being located at earth terminal 30 are outside and the chute 12 of corresponding shell 10 upper edge earth terminals 30 glide directions with it, and earth terminal 30 can stretch in chute 12 restricted portions.And realize by positioner the location of earth terminal 30, simultaneously referring to Fig. 5, Fig. 6, positioner comprises strip projected parts 34 and the projection 22 on cover 20 bottom surfaces of correspondence with it above the sliding part 32 of being located at earth terminal 30, among Fig. 7 as seen, when earth terminal 30 outwards spurs, when the projection 33 of stopping means pushes up the end of chute 12, projection 22 on the cover 20 in the positioner just misses the strip projection 34 of sliding part, earth terminal 30 is blocked at two, and this location is the operating state among Fig. 3.

Earth terminal 30 of the present utility model is plastic materials, aspect intensity and the resistance to wear higher requirement is being arranged because of product again, same plastic material is difficult to meet the demands, so the earth terminal of the utility model adopts moulding process twice, as shown in Figure 6, the sliding part 32 of earth terminal 30 comprise sliding outer cover 35 and be fixedly connected in the sliding outer cover 35 and with Plug Division 31 integrated connecting portions 36, the projection 33 of slip stopping means and the strip projected parts 34 of positioner are located at sliding outer cover 35 corresponding positions.When earth terminal 30 is in the service position, be similar to overhanging beam structure (seeing Fig. 3, Fig. 7), so ground connection terminal material and structure are had higher requirement, consider the safety size restrictions, at the Plug Division 31 of earth terminal 30 and junction formation one neck that concaves 37 (as shown in Figure 6) of connecting portion 36, this position is a region of stress concentration, and this has more increased the requirement to the raw material fracture strength.So the utility model sliding outer cover adopt plastics wear-resisting and that have a plastic deformation to make, Plug Division and integrated with it connecting portion are made by the plastic-steel material, fracture strength is up to 248MPa, near building iron material characteristic, far above the fracture strength (140MPa) of general plastic material.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, its framework form is flexible and changeable, can the subseries product.Just make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
