Description

The plug construction improvement

The utility model relates to a kind of line connector in the essential electronic element, refers in particular to the left and right conducting strip in the plug is separated especially to come, and reducing the chance that wherein is short-circuited because of moisture penetration, and guarantees device safe in utilization.

Prosperity along with science and technology, progress of industry, novel practical product of all kinds is invented one after another, and be applied among the daily life, in the life of affluence, various products are except convenient the use, and " fail safe " paid attention to by everybody, electrical appliance particularly is especially with the small household appliances of daily life.Because if electric leakage or short circuit take place, the lighter gets an electric shock, weight person is dead or breaking out of fire and family ruin the people and die, so in the use can not be careless.Plug then is a structure necessary in the various household electrical appliances, and therefore safe plug construction design is more and more important.Because the use of Christmas lamp is frequent in recent years, extend in the outdoor space by indoor, in outdoor temperature, under the situation that humidity all is difficult for controlling, the generation of plug waterproof and minimizing short circuit also seems important more, and therefore the U.S. classifies waterproof as an important test event already in the check of plug now, causes danger when avoiding children to touch accidentally simultaneously, also make it be difficult for decomposing as far as possible, to increase the fail safe on using.

The purpose of this utility model is to propose a kind of by shell, one body, one lid, a left side, the plug construction improvement that a right conducting strip and a L shaped conducting strip are formed, wherein dash forward and establish a raised line in the left slot right side on body, and be provided with a groove in the shell corresponding position, in addition one mating groove is arranged in a body storage tank two sides depression of insuring, and cooperate this place to be equipped with card article in the lid bottom surface, lid can be locked on the body during assembling, so just, can be a left side, right conducting strip separates out respectively, make water be difficult for infiltration and wherein have fail safe, thereby solved the existing in prior technology problem.

The technical scheme that the utility model adopted is, it is mainly by a shell, one body, one lid, a left side, a right conducting strip and a L shaped conducting strip are formed, on this body, respectively be provided with left slot, right slot, fuse storage tank and guide groove etc., make a left side, right conducting strip, fuse, L shaped conducting strip is wherein ccontaining, body then is arranged in the shell, this shell one side then keeps an opening, its position is the position of the fuse storage tank of corresponding body, be placed in this place for lid, it is characterized in that: set up a raised line near this slot place, left side on this body, and be embedded in the longitudinal fluting that is socketed in this external shell, these fuse storage tank both sides then are provided with vertical mating groove on body, set vertical two card articles in this lid back side are then wherein chimeric, and by a screw lid are locked in the body place.

Fig. 2 is an exploded view of the present utility model.

Fig. 3 is that body of the present utility model will insert the schematic diagram in the shell.

Schematic diagram when Fig. 4 locks for the utility model lid.

Further specify preferred embodiment of the present utility model in conjunction with above-mentioned each accompanying drawing now, as depicted in figs. 1 and 2, the utility model mainly is made up of a shell (1), a body (2), a lid (3), left conducting strip (4), right conducting strip (5) and L shaped conducting strip (6).This body (2) is gone up both sides and is provided with left longitudinally slot (21), right slot (22), in order to ccontaining should a left side, right conducting strip (4), (5), at the center-right fuse storage tank (23) that then is provided with, it also communicates with right slot (22), in order to put a fuse (7), this L shaped conducting strip (6) then places the guide groove (24) of fuse storage tank (23) below, by right conducting strip (5), fuse (7), L shaped conducting strip (6) constitutes a conductive circuit, bottom on this body (2) then is provided with approaching channel (25), use making the electric wire (8) that connects left conducting strip (4) and L shaped conducting strip (6) can extend to the external world thus, above-mentioned structure promptly constitutes the required basic status of plug.

Improvement part of the present utility model is on this body (2), locate to set up a raised line (26) near this left side slot (21), as shown in Figure 3, it is in order to separate ccontaining space that should left side conducting strip (4), combination back, and on body (2), this fuse storage tank (23) and right slot (22) both sides then are provided with mating groove (27) longitudinally, in order to the combination back zone every and envelope between the accommodation space of right conducting strip (5) and L shaped conducting strip (6), on this body (2), then have additional a screw hole (28) in addition, screw (9) for this lid of locking (3) uses, this shell (1) volume inside mainly is the face shaping that cooperates body (2), but set up in it one with the corresponding longitudinal fluting in body (2) raised line (26) position (11), make this raised line (26) can be wherein chimeric after combination, be provided with a square opening (12) in this shell (1) one side in addition, lid (3) is provided with wherein, with sealing fuse storage tank (23), this opening (12) bottom notch one slot part (13), with so that the bar portion (31) of lid (3) bottom but holding wherein.This lid (3) is mainly in order to sealing fuse storage tank (23) and the extraneous space that communicates, so its first half place is provided with one and runs through screw hole (34), be locked on the body (2) for a screw (9), its top is provided with one and pulls raised line (32), as shown in Figure 4, so that pick up or place, its back side then is provided with two card articles (33) in vertical mode, its position is just corresponding with the mating groove (27) of this body (2), so that lid (3) can seal right conducting strip (5) when covering, fuse (7), the formed circuit of L shaped conducting strip (6) is to prevent the water impervious wherein.

Entire combination mode of the present utility model, at first be with this left side, right conducting strip (4), (5), fuse (7) and L shaped conducting strip are inserted it respectively at the corresponding left slot of body (2) (21), right slot (22), fuse storage tank (23) and guide groove (24), as shown in Figure 3, again body (2) is inserted in the shell (1) from top to bottom, this raised line (26) is embedded in the groove (11), promptly fix both positions, earlier the bar portion (31) of this lid (3) bottom is inserted in the slot part (13) of shell (1) opening (12) again, make lid (3) sealing opening (12) again, simultaneously be locked in body (2) and locate, be about to each member assembling and finish with screw (9).By the design of raised line (26) with groove (11), accommodation space sealing with left conducting strip (4), and utilize card article (33) to be embedded in mating groove (27), promptly seal the formed circuit of right conducting strip (5) space, this can make aqueous vapor be difficult for infiltrating in the plug on the one hand, if infiltration is also come because of two conducting strips separate already accidentally, be difficult for the situation that generation is switched on and is short-circuited with water as medium, on the other hand so be a kind of safe plug construction.

The above-mentioned detailed description of the utility model; it only is the detailed description of a preferred embodiment of the present utility model; can not limit practical range of the present utility model with this; be all identical change and modifications of being done according to the utility model scope of patent protection, all should belong to the scope that the utility model is protected.
