The socket board 2 may include a panel connected to the profile 1 and a plurality of sockets disposed on the panel, the sockets may be received in the profile 1, and the hanging lugs 3 may be disposed at both ends of the profile 1 along the long axis direction.

As shown with particular reference to fig. 3 to 5, the profile 1 of the present embodiment may include a main body, which may include a first side plate 11, a second side plate 12, and a connecting plate 13 for connecting the first side plate 11 and the second side plate 12. The first side plate 11, the second side plate 12 and the connecting plate 13 enclose an inner cavity, in which the socket can be received. The inner cavity can be internally provided with a first clamping unit and a plurality of second clamping units, the first clamping unit and the second clamping units are distributed at intervals along the depth direction of the inner cavity, and the first clamping unit is positioned on one side, far away from the connecting plate 13, of each second clamping unit.

The first clamping unit includes two first clamping pieces 14 oppositely disposed on the first side plate 11 and the second side plate 12, or the first clamping unit includes two first clamping pieces 14, one of the first clamping pieces 14 is disposed on the first side plate 11, the other first clamping piece 14 is disposed on the second side plate 12, and the first clamping pieces 14 on the first side plate 11 and the second side plate 12 are oppositely disposed. The two first clamping members 14 extend in opposite directions to form first supporting portions for supporting the socket board 2, and the two first clamping members 14 both extend in the long axis direction of the profile 1, that is, the two first supporting portions both extend in the long axis direction of the profile 1. The second clamping unit includes two second clamping pieces 15 oppositely disposed on the first side plate 11 and the second side plate 12, or each second clamping unit includes two second clamping pieces 15, one of the second clamping pieces 15 is disposed on the first side plate 11, the other second clamping piece 15 is disposed on the second side plate 12, and the second clamping pieces 15 on the first side plate 11 and the second side plate 12 are oppositely disposed. Two second clamping pieces 15 of any second clamping unit extend along opposite directions to form a second supporting portion, and the two second clamping pieces 15 extend along the long axis direction of the section bar 1, namely, the two second supporting portions extend along the long axis direction of the section bar 1.

The first clamping unit extending along the long axis direction of the profile 1 is disposed in the inner cavity of the profile 1 in this embodiment, and since the two first clamping members 14 of the first clamping unit can extend to both ends of the long axis direction of the profile 1, the socket board 2 can be supported and fixed by the strip-shaped first clamping unit no matter the power distribution unit is long or short, or the power distribution unit has different functions and different insertion positions.

By the structure, when in production, the long-sized section bar 1 of the embodiment can be produced by only one set of equipment (such as a die), and then a small section of the section bar 1 with corresponding size can be cut from the long-sized section bar 1 to produce the power distribution unit according to the length of the shell of the power distribution unit required by a customer. The characteristic that first joint unit and second joint unit extend along the length direction of section bar 1 can make a small segment section bar 1 of arbitrary intercepting all have first joint unit and second joint unit, has guaranteed that a small segment section bar 1 of arbitrary intercepting all can support and fix different power distribution unit's socket board 2. Therefore, the profile 1 of the embodiment can be applied to power distribution units with different lengths and sizes and different socket boards 2, so that the number of fixed products of the shell of the power distribution unit can be reduced, the production efficiency is improved, the inventory caused by different types of the profile 1 is reduced, the process is simplified, the die cost is reduced, and meanwhile, the product quality control is facilitated.

Specifically, as shown in fig. 4 and 5, the profile 1 of the present embodiment is substantially U-shaped, an inner cavity defined by the first side plate 11, the second side plate 12, and the connecting plate 13 has an opening, the connecting plate 13 is a bottom of the inner cavity, and a direction from the opening to the bottom is a depth direction of the inner cavity. The first clamping unit is arranged in the inner cavity close to the opening so as to support and fix the socket board 2, and the second clamping unit is arranged on one side of the first clamping unit facing the connecting board 13.

Further, as shown in fig. 4 and 5, the first supporting portion of the present embodiment may have a square cross section perpendicular to the long axis direction thereof. Preferably, one of the first supporting portion that is far away from first side plate 11 or second side plate 12 serves and can also be equipped with and be used for carrying out spacing portion to socket board 2, and first supporting portion can also carry out spacing to socket board 2 simultaneously, avoids socket board 2 to remove along the direction that deviates from connecting plate 13. An L-shape can be formed between the limiting part and the first supporting part.

As shown in fig. 6, the power distribution unit of this embodiment may further include a PCB4 soldered to the socket board 2, and the electronic components on the PCB4 are electrically connected to the electronic components on the socket. The PCB4 is located on the side of the socket board 2 facing the connection board 13 and is connected to any of the second clamping units. The PCB4 connected with the socket can control the on-off function of the socket, can also detect the electrical parameters of the socket and the like, and realizes the function diversification of the power distribution unit.

Referring to fig. 4 and 5, the cross section of the second support portion perpendicular to the long axis direction thereof may be circular or arc-shaped, so that the hanging lug 3 may be connected to the second support portion by a tapping screw (tapping an originally smooth mounting hole during connection), and thus, the hanging lug 3 may directly seal the end of the section bar 1, and a material for sealing the end of the section bar 1 may be omitted. Specifically, a mounting hole can be formed in one side of the hanging lug 3 connected with the section bar 1, and when the hanging lug 3 is mounted with the section bar 1, a tapping screw is screwed into the circular or arc-shaped second supporting part after penetrating through the mounting hole, so that the hanging lug 3 can be fixed. When the second supporting portion is arc-shaped, it is preferably arc-shaped, the notches of the two arc-shaped second supporting portions (i.e. the chords corresponding to the arc-shaped second supporting portions) are oppositely arranged (or oppositely arranged) so as to clamp the PCB4, and the length of the chord corresponding to the arc-shaped second supporting portion may be equal to or slightly greater than the thickness of the PCB4, so as to avoid that the notches of the second supporting portion are too large, which results in insufficient connecting force between the second supporting portion and the tapping screw.

Of course, a section perpendicular to the long axis direction of a part of the second support portion not used for mounting the hanging lug 3 may be square, and in this case, it may be used only for supporting the PCB 4.

The section bar 1 of the embodiment can be integrally formed by adopting aluminum alloy through the extrusion die, so that the section bar has the advantages of high forming efficiency, high precision and the like. The assembly process of the power distribution unit of the present embodiment is as follows: according to the length of the power distribution unit (or the length of the socket board 2), cutting a corresponding small section of the section bar 1 from the long-strip-shaped section bar 1 (namely, the section bar 1 with the proper length required by a single power distribution unit); inserting the socket board 2 from one end of the long axis direction of the section bar 1 until two ends of the socket board 2 are aligned with two ends of the section bar 1, and when the PCB4 is welded below the socket board 2, before inserting, ensuring that the PCB4 is aligned with the second supporting part, and then inserting; and the two hanging lugs 3 are respectively fixed on the two ends of the section bar 1 by self-tapping screws.
