Abstract

The present invention relates to an elastic sheet for a conductive sheet of a socket, which comprises the members of a base, a conductive sheet, etc. of a socket, wherein the base of the socket is provided with plug jacks for the insertion of pins of a plug; the base of the socket, which is at both sides in each plug jack, is provided with stop blocks; the conductive sheet is provided with clamping sheets at the parts corresponding to the plug jacks of the socket; the side surface of the sheet body of each clamping sheet is rotated and bent in a direction which not face the contact surface of the pins of the plug to form at least two elastic sheets, and the elastic sheets are butted against the stop blocks of the base. Thus, the clamping sheets can have good clamping force to stably clamp the pins of the plug.

Description

Socket

The present invention relates to a kind of socket, relevant with the shell fragment of conducting sheet in socket especially.

At present, electrical home appliances all utilizes attaching plug by drawing electricity usage in the socket, therefore the utilization of electric power has become the some of all family lives, and a kind of design is as shown in figure 10 arranged in the socket of commonly seeing, it establishes two groups of conducting strip B on a socket A, some groups of jacks are respectively established in the corresponding position of these two groups of conducting strip B, wherein the root edge of the relative jack B1 of conducting strip B is all established two intermediate plate B2 and is implemented to plug for plug base pin, and be subjected to two intermediate plate B2 clampings, its clamping force of use initial stage still claims well, right plug base pin insert pull of a specified duration in the time one of the conducting strip B folder B2 of place, easily make conducting strip B intermediate plate B2 produce loose slightly situation, and the loose situation of this kind intermediate plate B2 is especially obvious when plugging the heavier transformer type plug of weight, often causes losing the strength of gripping, it is loosening to cause plug, loose contact, even the generation electric wire cocks off; In addition, the clamping force of the intermediate plate plug base pin that B2 bestows of general conducting sheet in socket B is wayward, lacks flexibility, and produces too tight or too loose situation when often plugging, product texture thereby difficult the lifting, and industrial competitiveness lowers relatively.

Purpose of the present invention promptly is to provide a kind of socket, when pulling to insert at pin, can provide the conducting sheet in socket that suitably grips power.

For reaching above-mentioned purpose, the present invention includes members such as the pedestal of socket and conducting strip, socket is provided with the jack of planting for the pin of plug in pedestal, and has block on the pedestal of the socket of both sides in the jack, and the jack of conducting strip respective socket and be provided with intermediate plate, there is the above shell fragment of a slice the side of intermediate plate lamellar body to non-plug base pin contact-making surface revolution bending forming, and shell fragment is against on the block of aforementioned pedestal.

Shell fragment is by punching press relief moulding in the intermediate plate lamellar body.

After adopting said structure, when the present invention was plugged in receptacle sockets when plug base pin, pin made that the conducting strip intermediate plate is little to support, and shell fragment is compeled to be against block and produced reaction force, made the excellent power of gripping of intermediate plate tool one, with firm clamping plug base pin.

Below in conjunction with drawings and Examples, the utility model is further described.

The assembled sectional view of product is commonly used by Figure 10 system.

Present invention can be implemented in most sockets of commonly using, the conducting strip system of all sockets shapes with sheet metal, all can utilize the present invention to obtain better effect, below cited embodiment, just be the example of the invention process at a pair of three conversion sockets.

See also Fig. 1, present embodiment mainly comprises elements such as socket 1, conducting strip 2, wherein:

Socket 1 can be covered by symmetrical upper and lower casing 11,12 and form, on the socket 1 except that the lateral margin at pin place, all the other each sides all offer jack 13 (per two jacks 13 are a group), and the outside of conducting strip 2 intermediate plates described later relatively 21 positions is one-body molded or be fixed with the block 14 of upright sheet in pedestal, is provided with some maintenance pieces 15 at the pedestal appropriate location in addition.

Conducting strip 2 is a conductive lamellar body, it is by sheet metal punching press bending forming, socket 1 jack 13 places stand to be bent with two intermediate plates 21 relatively, the gap that two intermediate plates are 21, suitable can inserting for the pin of plug pulled, this folder place 21 is at ring edge either side, to non-plug base pin contact edge revolution bending forming one shell fragment 211.

During combination, as shown in Figure 2, conducting strip 2 abuts against by maintenance piece 15 and is positioned in the socket 1, and the shell fragment 211 of conducting strip 2 intermediate plates 21 then contact supports the block 14 that ends at socket 1; When desire is plugged in socket 1 jack 13 with plug 3 pins 31, as shown in Figure 3, plug 3 pins 31 appearances are inserted in 21 of two intermediate plates, at this moment, the elasticity that intermediate plate 21 is possessed itself is suitable to make its little supporting, and makes its compression shell fragment 211 compel to support socket 1 block 14 of two sides, because shell fragment 211 back bending moulding, so shell fragment 211 will produce reaction force and execute again on intermediate plate 21, make intermediate plate 21 generations one excellent grip strength, and clamping plug 3 pins 31 firmly; Again, by shell fragment 211 permanent support to end in the gap of block 14, two intermediate plates 2 of socket 1 will be not can not inserting pull and extract excessively because of plug 3 frequent enlarge, can effectively avoid plug 3 to insert the loosening drawbacks of pulling.

In the above-described embodiment, shell fragment 211 is to bend and moulding with the upper limb and the revolution of root edge place of single lamellar body kenel by intermediate plate 21, but except that this kenel, if the shell fragment 211 by (being multiple-piece) more than intermediate plate 21 ring edge either side revolution bending forming a slices also belongs to the feasible example of the present invention (as shown in Figure 4); Certainly, if turn round bending forming shell fragment 211 simultaneously, also belong to feasible (as shown in Figure 5) by the both sides even three sides of intermediate plate 21 lamellar bodies.

And the non-the foregoing description that is confined to of structure of the present invention, the socket of any other form (as wall socket, extended line socket), its conducting strip is also all applicable, shown in Fig. 6,7, be an extended line socket 4, this pedestal is provided with aftermentioned conducting strip 5 intermediate plates 51 outsides in correspondence and forms block 41, and conducting strip 5 then cooperates bolting element 42 maintenances in pedestal, suitable can being supported by the shell fragment 511 of conducting strip 5 intermediate plates 51 ended on the block 41 of pedestal, and this also is the feasible embodiment of the present invention.

In addition, the pin of some plugs is made as the round bar kenel, and corresponding to the conducting sheet in socket 6 of this type plug, its intermediate plate 61 positions are made as arcuation, and its shell fragment 611 then extends (as shown in Figure 8) by intermediate plate 61 lateral margins of arcuation.

In addition, the intermediate plate of commonly using the conducting strip of some sockets is not two one group, and only is the monolithic kenel, and it touches by single lamellar body and plug base pin and conducts electricity, and for the socket of this type of one chip intermediate plate, this case also can be implemented.

More than cited various embodiment, shell fragment is all by the lateral margin of intermediate plate revolution bending forming, but the sole mode of this non-its moulding; See also Fig. 9, this example shows shell fragment 71, and relief is against on the block body (not shown) thus by the intermediate plate direct punching press in 7 body places, also can possess aforesaid practical function.
