Description

Technical Field

[0001] The utility model relates to the technical field of sockets, and more specifically to a power rail and a rail socket. Background Art

[0002] At present, people are using more and more electrical appliances, and the number of wall sockets required is also increasing, especially in scenes such as kitchens, living rooms, and conference rooms. The number of ordinary wall sockets is often not enough. If there are not enough installation locations for wall sockets when decorating the house, it will be very inconvenient to add wall sockets later. The track sockets on the market can meet people's demand for wall sockets without changing the circuit layout of the house.

[0003] The track socket includes an electrical connector and a long strip of power track. The power track is installed on the wall. A track slot is provided on the power track. A track socket electrically connected to the wall power line is provided in the power track. The electrical connector has a conductive sheet and a socket. When the track socket is used, the conductive sheet of the electrical connector is inserted from the track slot and contacts the track socket. At this time, the plug of the electrical appliance can be inserted into the socket of the electrical connector to obtain electricity. Multiple electrical connectors can be plugged into the track socket to adapt to the number of electrical appliances; the electrical connector can also slide arbitrarily in the track slot to adapt to the placement of the electrical appliance.

[0004] In the power rail of the prior art, the conductive sheet of the electrical connector and the rail socket are in surface contact, such as the structure described in the Chinese patent application number 202010712396.8. When the electrical connector slides in the rail slot, the friction surface between the conductive sheet and the rail socket is large, and the wear is also high. Excessive wear will lead to insufficient clamping force between the conductive sheet and the rail socket, resulting in poor electrical contact. Therefore, this structure has high requirements for the surface processing accuracy of the rail socket and the conductive sheet. In addition, in the rail socket of the prior art, the E-pole conductor is directly exposed in the notch of the rail slot, which is easily covered with dust and oil, resulting in the inability of the electrical appliance to be grounded. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a power rail, which can reduce the wear between the conductive sheet and the rail sleeve and ensure that the conductive sheet and the rail sleeve have sufficient clamping force by improving the structure of the rail sleeve and changing the contact mode between the conductive sheet and the rail sleeve of the electrical connector, so as to avoid the problem of poor electrical contact.

[0050] Embodiment 2:

[0051] like Figure 5 As shown in , the power rail of this embodiment differs from that of Embodiment 1 in that the N-pole bracket 3-1, the L-pole bracket 3-2 and the E-pole bracket 3-3 are an integrated structure and can be assembled in the rail inner cavity 2 at one time.

[0052] Embodiment 3:

[0053] The track socket of the utility model comprises a power track as described in Example 1, wherein at least one electrical connector is arranged on the power track, wherein the electrical connector is inserted into the track inner cavity 2 through the track slot 1-1 and can slide along the track slot 1-1, wherein an N-pole socket, an L-pole socket and an E-pole socket are arranged on the outer side of the electrical connector, wherein an N-pole conductive sheet 5, an L-pole conductive sheet 6 and an E-pole conductive sheet 7 which are respectively electrically connected to the N-pole socket, the L-pole socket and the E-pole socket are arranged inside the electrical connector, wherein an N-pole conductive sheet 5, an L-pole conductive sheet 6 and an E-pole conductive sheet 7 which are respectively electrically connected to the N-pole socket, the L-pole socket and the E-pole socket are respectively arranged on the N-pole conductive sheet 5, the L-pole conductive sheet 6 and the E-pole conductive sheet 7, wherein the N-pole electrical contact 5-1, the L-pole electrical contact 6-1 and the E-pole electrical contact 7-1 are all hemispherical.

[0054] like Figure 3 and Figure 4As shown in the figure, the N-pole electrical contact 5-1 only needs to extend into the opening of the N limit position cavity 3-11 to make electrical contact with the N-pole second bend portion 4-14 and the V-shaped protrusion of the N-pole electrical contact portion 4-12; the L-pole electrical contact 6-1 only needs to extend into the opening of the L limit position cavity 3-21 to make electrical contact with the L-pole second bend portion 4-24 and the V-shaped protrusion of the L-pole electrical contact portion 4-22; and the N-pole electrical contact 5-1 only needs to face the opening of the E limit position cavity 3-31 to make electrical contact with the E-pole second bend portion 4-34 and the V-shaped protrusion of the E-pole electrical contact portion 4-32.

[0055] The width of the N-pole gap groove 4-15 is smaller than the width of the N-pole electrical contact 5-1, and the N-pole electrical contact 5-1 can stop at any position on the N-pole electrical contact portion 4-12. When the N-pole electrical contact 5-1 is in electrical contact with any part on both sides of the N-pole gap groove 4-15 at the same time, the N-pole gap groove 4-15 can limit the position of the N-pole electrical contact 5-1.

[0056] In other embodiments, in order to further facilitate the electrical contact between the electrical connector and the track socket 4, the N-pole second bent portion 4-14 can be made opposite to the opening of the N-limit position cavity 3-11, or the V-shaped protrusion of the N-pole electrical contact portion 4-12 can be made opposite to the opening of the N-limit position cavity 3-11, so that the N-pole electrical contact 5-1 can be made electrically in contact with the N-pole second bent portion 4-14 or the V-shaped protrusion of the N-pole electrical contact portion 4-12 just by facing the opening of the N-limit position cavity 3-11. In this way, the N-pole conductor 4-1 can also be set to the same shape as the E-pole conductor 4-3, so that the N-pole mounting portion 4-11 is also L-shaped.

[0057] Similarly, the L-pole second bending portion 4-24 can be made to face the opening of the L-limit position cavity 3-21, or the V-shaped protrusion of the L-pole electrical contact portion 4-22 can be made to face the opening of the L-limit position cavity 3-21, so that the L-pole electrical contact 6-1 can be made to make electrical contact with the L-pole second bending portion 4-24 or the V-shaped protrusion of the L-pole electrical contact portion 4-22 just by facing the opening of the L-limit position cavity 3-21. In this way, the L-pole conductor 4-2 can also be set to the same shape as the E-pole conductor 4-3, so that the L-pole mounting portion 4-21 is also L-shaped.

[0058] The above are only specific embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. If the present invention is modified or replaced by equivalents without departing from the spirit and scope of the present invention, they should be included in the protection scope of the claims of the present invention.
