Description

Insulated type is stablized the plug locating rack

Technical field:

The utility model is relevant with attaching plug, refers to a kind of have insulation, the stable plug locating rack that reaches positioning action especially.

Background technology:

Traditional plug locating rack (or being called interior die holder) with insulation effect as shown in Figure 1, has a matrix 10 made from plastic material, one-body molded two insulation divisions 11,12 of these matrix 10 1 side surfaces or establish a terminal ring 17 again; Wherein, this two insulation division 11,12 is used for coating the undergauge body portion 132,142 (as Fig. 2) of location two power supply terminals, 13,14 plug end 131,141, and exposing partly of plug end 131,141 equated with the external diameter of two insulation divisions 11,12; 17 on this terminal ring supplies earth terminal 15 to place the location.After the wire connecting portion 133,143,153 of each terminal 13,14,15 connected power line, moulding coated a shell body and forms a plug 16 outside matrix 10.

This plug 16 inserts in the jack 21 of socket 20 reservations with the plug end 131,141,151 that exposes, and stretches in the conductive clip 22 of socket 20 inside.Many users when using socket head, the malposition of finger grip plug, cause finger have contact power supply terminal 13,14 may, insert with or easily get an electric shock when dialling except that plug.Therefore 11,12 of this insulation divisions are the pivot prevention structures that disappears that designs at the problems referred to above, allow the user reduce the danger that produces because of contact power supply terminal 13,14.

Except above-mentioned safety in utilization, plug 16 waits to solve with the safety problem that other are also arranged that cooperates of socket 20.For example: the jack 21 of socket 20 is the plug end 131 of plug 16 for convenience, 141,151 pass through, the aperture is slightly larger than plug end 131 usually, 141,151, therefore plug 16 inserts socket 20, the Yu crack that jack 21 provides plug 16 to rock, some careless users can arbitrarily on the skew plug 16 be inserted in the socket 20 in these Yu cracks, perhaps pullling or the collision of external force that other can't be expected because of the rear end power line, make plug 16 take place crooked even the gesture of disengaging is outward arranged, cause plug end 131,141,151 with conductive clip 22 loose contacts, be short-circuited easily, the danger of cocking off.

Summary of the invention:

The technical problems to be solved in the utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of insulated type to stablize the plug locating rack, reaches firm plant plug, guarantees purpose of safety.

The technical solution of the utility model is as follows:

A kind of insulated type is stablized the plug locating rack, mainly coats at least two power supply terminals with a locating rack, and its outer moulding one shell that coats forms a plug; The terminal pins portion of this plug inserts via the jack of socket, and stretches and touch in the conductive clip of socket inside, it is characterized in that:

This locating rack one side surface is integrally formed with at least two power supply terminal dead rings, and the both sides correspondence position of this each dead ring is respectively established a flexure strip, respectively establishes a location salient point on each flexure strip, and this power supply terminal dead ring radially protrudes in this power supply terminal pin portion.

This locating rack one side surface also is integrally formed with an earth terminal dead ring, coats location one earth terminal; This earth terminal dead ring radially protrudes from this earth terminal pin portion; The both sides correspondence position of this earth terminal dead ring is respectively established a flexure strip, respectively establishes a location salient point on each flexure strip.

Progressive effect of the present utility model is:

The user must be inserted to plug successfully being inserted in the jack with correct for dead ring of the present utility model, can limit some careless users and must insert plug and random oblique cutting with correct direction; This dead ring cooperates with jack and keeps the plug location, makes not the pullling influence such as the external force collision that maybe can't expect of reason power line and crooked of plug, guarantees that plug terminal stably contacts with the socket conductive clip, danger such as avoid short circuit or cock off.This dead ring also has the protection user and avoids danger because of improper gripping plug contact terminal accidental shock.

Embodiment:

See also Fig. 4, Fig. 5 and Fig. 6; A kind of insulated type of the utility model is stablized the plug locating rack, mainly comprises:

One locating rack 30, but the section configuration mated plug form factors of this locating rack 30 is designed to various types, and this locating rack 30 is made with insulating material, adopts plastic cement one-body molded usually; One side surface is integrally formed with at least two power supply terminal dead rings 31,32 or establishes an earth terminal dead ring 33 again, the both sides correspondence position of this each dead ring 31,32,33 is respectively established a flexure strip 311,321,331, respectively establish a location salient point 312,322,332 on each flexure strip 311,321,331, the section configuration of above-mentioned each dead ring 31,32,33 and interior hole dimension need be decided on the power supply terminal 40,41 of plug and the external form and the size of earth terminal 42; This power supply terminal 40,41 and earth terminal 42 insert [taking the one perfusion to coat after perhaps terminal being located according to the precalculated position is coated on locating rack 30 outside power supply and the earth terminal] by the rear of this locating rack 30 respectively, plug end 43,44,45 close-fittings that make terminal are in this power supply terminal dead ring 31,32 and earth terminal dead ring 33, terminals 46,47,48 then are exposed to the opposite side of locating rack 30, preparation clamping connection power line.Terminals 46,47, the 48 outer moulding of this locating rack 30 and each terminal 40,41,42 coat a housing department, form a plug 50.

This plug 50 inserts in the socket 60, as Fig. 7, this plug end 43,44,45 is stretched and is touched in the conductive clip 61 of socket 60 inside, and the outer power supply terminal dead ring 31,32 that protrudes in terminal body portion, 33 correspondences of earth terminal dead ring also are filled in the jack 62 of socket 60, and add strong fix with positioning convex point 312,322,332 and hole wall, eliminate the Yu crack in hole, and resist in the open end of this conductive clip 61 open end of each ring, and plug 50 is positioned in the socket 60.

Above-mentioned station-keeping mode has following advantage:

This power supply terminal dead ring 31,32 and earth terminal dead ring 33 be packed in the jack 62 of socket 60, eliminated the Yu crack that can allow plug 50 become flexible in the prior art, the user must correctly insert to plug 50 is successfully inserted in the jack 62, have slightly and crookedly promptly can make dead ring 31,32,33 end conflict jack 62 edge outer walls and plug 50 can't be inserted in the hole, plug end 43,44,45 promptly can't contact with conductive clip 61, power supply can't conducting, so must insert plug 50 with correct direction when limiting some careless users, and random oblique cutting.The plug 50 that correct direction is inserted just can make dead ring 31,32,33 be packed in the jack 62 of socket 60, can keep plug 50 location by this, make not the pullling influence such as the external force collision that maybe can't expect of reason power line and crooked of plug 50, furthermore it, can guarantee that plug end 43,44,45 stably contacts with conductive clip 61, can eliminate the crooked or short circuit that caused or cock off etc. dangerous of partly coming off because of plug.Certainly, dead ring 31,32,33 of the present utility model also has the protection user, avoids the danger because of improper gripping plug contact terminal accidental shock.

In sum, the utility model provides plug 50 to have insulation, location and the stable effect of inserting in the socket 60.And the utility model dead ring 31,32,33 can be applicable to the plug 50 of various specification, extremely shown in Figure 35 as Fig. 8, for avoiding length too numerous and diverse, so the label of relevant plug is all with 50 expressions, and Fig. 9,11,13 ... 35 correspondingly is Fig. 8,10,12 respectively ... schematic diagram is looked on a left side of 34, hereby Chen Ming.
