Description

Technical Field

[0001] The utility model relates to the technical field of power distribution units, and in particular to a profile housing locking structure, a profile for electrical equipment provided with the profile housing locking structure, and a power distribution unit provided with the profile for electrical equipment. Background Art

[0002] The profile shell locking structure is a locking structure used to temporarily fix the profile shells together. Common profile shell locking structures mainly include snap-on locking structures and fastener locking structures.

[0003] like Figure 1 As shown, the existing snap-on locking structure has the characteristics of compact structure and few parts. The existing snap-on locking structure mainly includes an upper hook connected to the upper shell of the profile and a lower hook connected to the lower shell of the profile. The structure can realize the locking connection of the upper shell of the profile and the lower shell of the profile by the upper hook and the lower hook engaging with each other.

[0004] like Figure 2 As shown, the existing fastener-type locking structure mainly includes connecting screws, connecting holes arranged on the upper shell of the profile and the lower shell of the profile, and a screw mounting seat arranged between the upper shell of the profile and the lower shell of the profile. The existing fastener-type locking structure realizes the locking connection between the upper shell of the profile and the lower shell of the profile through a threaded connection formed by the connecting screws penetrating the connecting holes and the screw mounting seat.

[0005] The applicant has found that the prior art has at least the following technical problems:

[0006] The existing snap-on locking structure can only be horizontal ( Figure 1 The front-to-back direction) is inserted for assembly and cannot be assembled along the vertical direction ( Figure 1 The assembling process is not only difficult, but also requires redundant design of components between the upper and lower shells of the profile to ensure that the lateral insertion of the upper shell of the profile is not interfered with (for example, the connecting wires between the upper shell of the power distribution unit and the lower shell of the profile need to be redundantly designed and designed to be longer), which will undoubtedly increase the cost.

[0007] The existing fastener-type locking structure requires the use of many connecting screws, which need to be aligned, aligned and rotated during installation. Installing multiple connecting screws together is time-consuming and labor-intensive, which increases the difficulty of assembly. In addition, the connecting screws themselves and the screw mounting seats threaded therewith will increase material and processing costs. Utility Model Content

[0041] When the upper hook 1 in the utility model is inserted into the installation chamber 7 from top to bottom, a plug insertion channel is formed between the concave part of the upper hook 1 and the concave part of the lower hook 3. When the locking plug 5 is inserted into the plug insertion channel, it can prevent the upper hook 1 from escaping from the lower hook 3 from the installation chamber 7. Compared with the snap-on locking structure in the prior art, the utility model can be assembled by inserting the upper hook 1 toward the lower hook 3 in the (vertical) direction from top to bottom, without the need to insert the snap-on horizontally. The assembly requires a small space and will not interfere with the surrounding structural parts. There is no need to make redundant design for the parts between the upper shell 12 of the profile and the lower shell 13 of the profile. Compared with the fastener-type locking structure in the prior art, there is no need to use connecting screws, which not only reduces the cost of connecting screws, but also saves the step of rotating screws, and the assembly efficiency is also higher.

[0042] As an optional implementation, the cross section of the locking plug 5 in this embodiment is circular. The locking plug 5 is preferably a cylindrical structure, which has few edges and can be plugged in at all angles, making it easy to assemble and manufacture.

[0043] As an optional implementation, the concave part of the upper hook 1 and the concave part of the lower hook 3 in this embodiment are both arc-shaped structures. The arc-shaped structure has fewer edges and corners, is less likely to cause stress concentration, has more reliable strength, is easy to manufacture, and has a more compact structure when matched with the locking plug 5.

[0044] As an optional implementation, in this embodiment, the upper hook 1, the profile upper seat 2 and the profile upper shell 12 are an integrated structure. Designing this structure as an integrated structure has the advantages of convenient batch manufacturing and relatively high structural strength at all locations.
