Abstract

The utility model belongs to the field of power sockets, which is the improvement of the safety socket of the utility model of patent number of China 94241748.8. The utility model has the advantages of higher safety factor and more practicality. The socket is characterized in that a button for controlling the metal in the fire wire jack of the socket to energize is arranged between the jacks of the socket. When no external force acts, the socket is at the same level with the panel, or a little lower than the panel. A plastic connecting fitting is added, and the plastic connecting fitting is provided with a nose bar whose cross-section is in the same shape and size with the outer end face of the button. The connecting fitting is appressed with the inner end of the plug foot. The plug must be inserted into the socket to the last four millimetres, and the button of the socket is pushed by the nose bar of the connecting fitting, causing the metal in the fire wire jack of the socket to energize.

Description

Safety socket

The utility model is the architecture advances about safety socket, belongs to the supply socket field.

China Patent No. is 94241748.8 safety socket, by a button above panel 5 millimeter is set between the socket panel jack, button is positioned at compression spring of end housing cover under the panel, sheet metal is fixedly connected with the metal clips of contact in the firewire jack, the metal clips tip side is close to the interior top of button, the metal clips that another fixedly connected power firestreak wiring part is arranged in the terminal corresponding position of metal clips, in fact the button of this between the receptacle sockets plays the on-off action of a control live wire power supply.Find that through practice also there is following defective in this safety socket: the button that 1, is provided with between jack exceeds socket panel 5 millimeter, just in case child uses metalwork when the jack interpolation, hand is in this position, might have a mind to or be not intended to take advantage of a situation press button, causes danger.2, often run into the plug of dismounting, three-pole plug particularly, a screw fixing hole is arranged between jack, still have darker hole after screw is fixing, behind the plug socket, button just in time is inserted in this hole, makes metal energising in the socket firewire jack so plug fails to promote to exceed the button of panel.3, exceed the interest that a button attracts child easily on the socket, increased unsafe factor.

The purpose of this utility model then is the problem at above-mentioned existence, proposes a kind of improved safety socket, and it becomes the push-button design that is provided with between jack not above panel, and can be complementary with any plug.

The purpose of this utility model can reach by following measure:

A kind of safety socket of being made up of panel, metalwork, housing and button is characterized in that the outer end of button between jack is concordant with the panel outer wall or be lower than the panel outer wall, and the nose bar that connects on the accessory is close to plug pin the inner.

The utility model has the advantages that: the socket secure coefficient further improves, child at random can not take advantage of a situation because of the motion of hand to socket aperture interpolation metalwork yet and cause danger by advancing button, and do not exceed the burdensome thing of panel on the socket, outward appearance is more attractive in appearance, takes off to connect accessory and can also limit child and make electrical appliance.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model multipurpose socket panel schematic diagram.

Fig. 3 is that the utility model two utmost point formula sockets connect the accessory schematic diagram.

Fig. 4 is that the utility model three-pole socket connects the accessory schematic diagram.

Below in conjunction with accompanying drawing the utility model is further described:

As depicted in figs. 1 and 2, be with the button 3 of compression spring 2 in the socket panel 1, when no external force promotes outer end, outer end is exposed in the through hole 4 on the panel 1 between the receptacle sockets, and concordant with socket panel 1 outer wall, or is lower than panel 1 outer wall slightly, when button 3 outer ends are lower than panel 1 outer wall, through hole 4 outer end bores are greater than inner bore, and the outer end of through hole 4 is toroidal, and the inner is the cylinder bodily form.The outer end of button 3 is positioned at tubaeform and cylindrical junction.When purpose is to use plug 5, also can sliding outer end if be fixed in the outer end that the nose bar that connects accessory 67 on the plug 5 is eccentric in button 3 slightly.The wall thickness at through hole 4 places on the panel 1 guarantees that the outer end portion of button 3 can be when no external force promotes the outer end of button 3, have greater than connecing the length of the nose bar 7 on the accessory 6 in through hole 4 as Fig. 3 and Fig. 4, purpose is the nose bar 7 on the accessory 6 of connecing that prevents to be fixed on the plug 5, advance button 3, make button 3 outer ends protrude the internal orifice of through hole 4, transfer to plug 5 back resiliences not come out.

As shown in Figure 3, Fig. 3 be two utmost point formula sockets 17 connect accessory 6, the plastic tab that connects accessory 6 has the through

hole

8 and 9 in the pin that can pass and be fixed in plug 5 more tightly, have between the through

hole

8 and 9 above the about 4 millimeters nose bar 7 of thin slice, set button outer end face shape and big or small the same between the cross sectional shape of nose bar 7 and size and two utmost point formula receptacle sockets, when 17 reeves of two utmost point formula sockets have the plug 5 that connects accessory 6, when not being inserted into last about 4 millimeters, socket button 3 is not advanced by the nose bar that connects accessory 6 on the plug 57, be connected in the shell fragment 12 of the contact-carrying 11 of metal 10 in the firewire jack, the shell fragment 16 of another contact-carrying 15 that is connected with the wiring 14 that is connected in power firestreak 13, still keep a gap, so the metalwork 10 in two utmost point formula socket firewire jacks does not have energized, the pin of plug 5 does not have certainly, when plug 5 inserts last about 4 millimeters one section, this moment, the diameter of your finger was bigger than it, finger does not just reach plug pin yet, yet the nose bar 7 that connects accessory 6 has advanced the button 3 of socket, contact on the shell fragment 11 is contacted with contact on the shell fragment 12, also just make metal energized in the socket firewire jack.

For the three-pole socket connects accessory, be applicable to three-pole socket 18 as Fig. 4, principle is identical with two utmost point formula sockets 17.

Claims

1, a kind of safety socket of being made up of panel, metalwork, housing and button is characterized in that the outer end of button between jack is concordant with the panel outer wall or be lower than the panel outer wall, and the nose bar that connects on the accessory is close to plug pin the inner.

2, safety socket according to claim 1 is characterized in that panel through hole outer end bore greater than inner bore, and the through hole outer end is toroidal, and is inner cylindrical.
