Abstract

The utility model relates to a track type power source bar socket and a track type power source bar socket plug which are arranged on the wall or the shelf for using by various electric appliances to connect with the power source. The utility model is characterized in that the surface of one side of a strip-shaped socket body (1) with arbitrary length is provided with a slot (2) which is communicated with a long groove (3) in the socket body (1), the upper surface, the lower surface and the side wall of the groove (3) are respectively provided with a conductive body (4), a plug which is matched with the utility model is in the cross shape, and the root parts of a left, a right and a middle contact conductance heads (6) are respectively provided with a telescopic spring (8). The utility model can replace the conductor wire in the wall. The power plug can be arbitrarily inserted along the length direction of the utility model particularly, and the insertion is convenient and safe.

Description

Track type power source bar socket and plug

The utility model relates to electric component, is supply socket and plug that a kind of electrical equipment is used.

The Fixed power-supply socket limited amount that disposes in the existing building construction, very incompatible with the electric equipment products that family is increasing, generally feeling indoor has the several sockets of number not enough, unique remedial measure is constantly to increase to drag the line socket plate, both used inconvenience, the long electric wire of promise is pulled and hauled a man horrible, and very dangerous.The Chinese patent communique discloses a kind of wall-enclosed type socket and plug in August, 88, and its socket is made with insulating material, vertically has two grooves at least, and length is arbitrarily long band body, and conductor is embedded in the groove.The plug that matches with this band shape socket is a kind of plug with three conduction inserted sheets parallel to each other (or make add spring leaf on the inserted sheet).This enclosure wall formula socket can inject appliance plug in the optional position of socket length direction, the unaccommodated problem of socket position that the position that has solved fixed socket occurs owing to the change of movable electrical appliances and furniture position.But, having three seams on the panel of this socket, fail safe is bad, although interpolation slit can be made into sealing or semi-enclosed, and this has increased the difficulty when inserting plug again.

The purpose of this utility model is in order to provide a kind of easy to use, fail safe is rail mounted power strip socket preferably, after being arranged on it on the wall, the electric wire in the both alternative existing wall that is laid in, but the power supply source plug inserts in any position of this rail mounted power strip socket length direction again.

The utility model of realizing above-mentioned purpose is, in a strip socket, be provided with one with the groove of socket respective length, have an interpolation slit that communicates with groove on socket one side surface, the groove above and below and with the trenched side-wall of interpolation slit opposite face on respectively be provided with an electric conductor, these three electric conductors can be respectively join with live wire, zero line and the earth connection of power line.The plug that matches with this socket is a kind of ten shape plugs, on the root that contacts conductive head of both sides and middle upper part coil tension spring is housed all.Said plug like this turns over 90 degree again behind the interpolation slit that inserts the bar socket with horizontal direction, then three contact conductive heads just closely contact with three electric conductors.

The utility model has the advantages that, the utility model is laid can local replace lead after being embedded in the wall, can insert attaching plug arbitrarily at its length direction, and very convenient, safe and reliable when inserting.

Embodiment of the present utility model as shown in drawings.

Description of drawings:

Fig. 1 is the front view of the utility model bar socket.

Fig. 2 is the transverse cross of Fig. 1.

Fig. 3 is the schematic diagram of shape plug in the utility model.

Fig. 4 is the contact conductive head amplification view partly of plug in the utility model.

See also Fig. 1.1 is strip insulated receptacle body among Fig. 1, and its length can be long arbitrarily.In the present embodiment, socket 1 is made of plastic, and the front of socket has interpolation slit 2, and the length of interpolation slit 2 is identical with the length of socket 1.Fig. 2 is the transverse cross-sectional view of this rail mounted power strip socket, see by figure, have in the socket 1 one with the groove 3 of the same length of socket, in the above and below of this groove 3 with on the side of interpolation slit 2, be embedded with copper sheet bar 4, zero line and live wire that upper and lower copper sheet bar is a power supply, the copper sheet bar of interpolation slit 2 right opposites is a ground wire.

The plug that matches with above-mentioned power strip socket as shown in Figure 3.See that by figure the head of connector assembly 7 is provided with the flexible contact conductive head 6 of three directions that are contained in the sheath body 5.See that by Fig. 4 the root of contact conductive head is provided with spring 8.When the plug of structure like this turns over 90 degree with horizontal direction again after interpolation slit 2 inserts sockets 1, two contact conductive heads 6 contact with upper and lower two flat copper slips in the socket 1 respectively about then on the plug, otherwise and compression spring 8(, spring 8 tightly is pressed against conductive head 6 on the copper sheet bar, assurance has excellent contact), 6 of the contact conductive heads at ten shape plug tops contact with copper sheet bar on the interpolation slit 2 right opposite cell walls and constitute ground connection.

Claims

1, a kind of in strip socket (1), having and socket (1) respective length groove (3), be provided with the rail mounted power strip socket of electric conductor (4) in the groove (3), it is characterized in that, have an interpolation slit (2) that communicates with groove (3) on socket (1) one side surface; Groove (3) above and below and with groove (3) sidewall of interpolation slit (2) opposite face on respectively be provided with an electric conductor (4).

2, a kind of and plug that matches of rail mounted power strip socket according to claim 1 is characterized in that this plug is ten shapes, and both sides and the middle root that contacts conductive head (6) all are equipped with coil tension spring (8).
