Description

Ultra-thin extension socket

Technical Field

The invention relates to the technical field of power sockets, in particular to an ultrathin extension socket.

Background

The strip plug is a multi-position socket with wires, also called a patch panel or a strip plug, and is provided with a plurality of power supply jacks. Most of the existing row inserts are of horizontal flat plate structures, only the upper end face is provided with a power jack, and the space utilization rate is low. Therefore, some manufacturers produce a multi-face socket, such as a chinese patent magic cube socket (patent No. 201520960718.5), and disclose a cube multi-face socket, each of which has a power jack on three faces. However, the thickness of the multi-face socket is thicker, and the thickness of the power socket is added, so that a larger width space is required when the multi-face socket is used; the square multi-face socket is not convenient to carry as a common row plug, and cannot be plugged in a gap of a luggage or a knapsack to be stored as a common row plug. Therefore, it is desirable to design an ultra-thin extension socket having multiple sides with power jacks.

The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.

As shown in fig. 1 to 11, the embodiment of the invention provides an ultrathin extension socket, which comprises a housing 10, an electrical component 20 positioned in the housing 10 and a power cord 30 electrically connected with the electrical component 20 and penetrating out of the housing 10, wherein the housing 10 is provided with a bottom plate 13, a first side plate 11 and a second side plate 12 opposite to the bottom plate 13, the first side plate 11 and the second side plate 12 are vertically arranged with the bottom plate 13, a first jack group 111 is arranged on the first side plate 11, a second jack group 121 is arranged on the second side plate 12, the electrical component 20 comprises a first power taking module 21 corresponding to the first jack group 111 and a second power taking module 22 corresponding to the second jack group 121, and the first jack group 111 and the second jack group 121 are arranged in a staggered manner, so that the first power taking module 21 and the second power taking module 22 are arranged in a staggered manner. Specific dislocation modes include up-and-down dislocation and/or left-and-right dislocation.

By arranging the first jack group 111 and the second jack group 121 in a staggered manner, the first power taking module 21 and the second power taking module 22 can be staggered, so that the thickness of the electrical assembly 20 is smaller than the sum of the thicknesses of the two power taking modules, and the thickness of the whole row of plugs is reduced. In the first embodiment shown in fig. 2, the first jack group 111 and the second jack group 121 are offset left and right, and the offset distance H1 between the first jack group 111 and the second jack group 121 is 8mm-10mm, preferably 9mm, so that the distance between the first power taking module 21 and the second power taking module 22 meets the national standard, and the situation that the distance between the first power taking module 21 and the second power taking module 22 is too large, the overall length of the electrical assembly 20 is too long, and the space utilization of the row socket is reduced is avoided. In the second embodiment shown in fig. 3, the first jack group 111 and the second jack group 121 are vertically staggered, and the range of the misalignment distance H2 between the first jack group 111 and the second jack group 121 is 8mm-10mm, preferably 9mm, so that the distance between the first power taking module 21 and the second power taking module 22 meets the national standard, and the situation that the distance between the first power taking module 21 and the second power taking module 22 is too large is avoided, the overall height of the electrical assembly 20 is too high, the space utilization of the row plug is reduced, and the row plug is unstable due to too high center of gravity. Of course, in other embodiments, as shown in fig. 11, the first jack set 111 and the second jack set 121 may be offset both up and down and left and right, i.e., the first jack set 111 is located obliquely above or obliquely below the second jack set 121.

As shown in fig. 6, taking the left-right offset of the first jack group 111 and the second jack group 121 as an example, after the first power taking module 21 and the second power taking module 22 are offset, the projections of the first power taking module 21 and the second power taking module 22 in the thickness direction of the casing 10 are at least partially overlapped, and the overlapping area can reach 90%, so that the thickness of the electrical component 20 is close to that of one power taking module, and the thickness of the row of inserts is smaller than that of the existing multi-face row of inserts.

As shown in fig. 4 to fig. 6, the first power taking module 21 includes a plurality of first sockets, the number of the first sockets corresponds to the number of the middle jacks of the first jack group 111, the first sockets include a first jack 214 and a first bottom 215, the first jack 214 is used for plugging with an electrode slice of a power plug, the first bottom 215 can have a through slot structure or a flat plate structure, and the thickness of the first power taking module 21 is the size from the first jack 214 to the first bottom 215. The second power taking module 22 comprises a plurality of second plug bushes, the number of the second plug bushes corresponds to the number of jacks in the second jack group 121, each second plug bush comprises a second jack 224 and a first bottom 215, the second jack 224 is used for being plugged with an electrode slice of a power plug, the second bottom 225 can be of a through slot structure or a flat plate structure, and the thickness of the second power taking module 22 is the size from the second jack 224 to the second bottom 225. The first and second inserts may be identical in construction, except that the first and second receptacles 214, 224 are oppositely oriented.

The first plug bush is arranged on one side of the second plug bush so as to realize dislocation arrangement of the first plug bush and the second plug bush. As shown in fig. 4, in the embodiment in which the first jack set 111 and the second jack set 121 are offset left and right, the first plug is located on the left side of the second plug. Preferably, in order to shorten the length of the electrical component 20, the space in the row of inserts is fully utilized, and the gap between the first insert sleeve and the second insert sleeve is 1mm-4mm. And the first receptacle 214 is relatively close to the second bottom 225 and the first bottom 215 is relatively close to the second receptacle 224 such that the projections of the first and second inserts in the thickness direction of the housing 10 at least partially overlap. As shown in fig. 6, the overlapping portion of the projections of the first and second sockets on the X plane exceeds 90%, so that the thickness H3 of the electrical component 20 approximates the dimensions of the first and second sockets, that is, the thicknesses of the first and second power taking modules 21 and 22, to shorten the overall thickness of the strip.

Based on the above structure, considering that the dimensions of the first and second sockets need to meet the national standard, plus the thicknesses of the socket and the safety door 43 therein, the distance between the first side plate 11 and the second side plate 12 is 30mm to 50mm, preferably 30mm to 35mm.

Of course, in other embodiments, the conductive element group may employ conductive wires, and the electrical connection with the first power taking module 21 and the second power taking module 22 may be implemented by welding.

It should be noted that, no matter the conductive member set is a flexible conductive wire or a rigid metal sheet, the conductive member set includes at least one live wire conductive member 23 and at least one neutral wire conductive member 24, and meanwhile, in the first power taking module 21, part of the first plug bush is electrically connected with the live wire conductive member 23, and part of the first plug bush is electrically connected with the neutral wire conductive member 24, so that the first power taking module 21 can be correspondingly plugged with the two-pole plug; in the second power taking module 22, part of the second plug bush is electrically connected with the live wire conductive member 23, and part of the second plug bush is electrically connected with the zero wire conductive member 24, so that the second power taking module 22 can be correspondingly plugged with the two-pole plug. In addition, the conductive member set may further include at least one grounding conductive member 25, and a portion of the first plug bush in the first power taking module 21 is electrically connected with the grounding conductive member 25, so that the first power taking module 21 may be plugged with the grounding plug of the diode band correspondingly, and a portion of the second plug bush in the second plug bush assembly is electrically connected with the grounding conductive member, so that the second power taking module 22 may be plugged with the grounding plug of the diode band correspondingly.
