[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] like Figure 1 and 2 As shown, the portable electrical device of the present invention comprises a body 2 and a pendant 1, wherein the pendant 1 is assembled and connected to the body 2, wherein the pendant 1 is made of metal material, for example, the pendant 1 is a steel structure pendant.

[0029] The communication device described in the present invention may be a switch (or a scene switch), a power supply (or a mobile power supply), a router, a gateway, a speaker, a remote control, a mobile terminal, or the like.

[0030] Through the pendant 1, the user can connect a soft rope, a lanyard, etc. to it, so as to carry the body 2 with him, so that the switch can be used at any time when needed, avoiding the inconvenience caused by moving around. And because the pendant 1 is made of metal material, the pendant 1 has a high strength, which can avoid the defect of easy breakage of existing injection molded parts, thereby ensuring safe and reliable use of the switch.

[0031] In addition, since the hanger 1 and the body 2 are assembled, the processing and assembly are more convenient. It should be noted that the assembled connection described in the present invention means that the hanger 1 and the body 2 are not formed in one piece, but are combined through a certain assembly relationship.

[0032] Specifically, in order to facilitate the hanging of connecting objects such as soft ropes and laces, the first end of the pendant 1 is constructed as a ring structure 11, and the second end of the pendant 1 is snap-connected with the main body 2.

[0033] like Figure 3 As shown, in the first embodiment of the present invention, the hanger 1 is an integrated structure. Specifically, the second end of the hanger 1 is sequentially provided with a necking portion 13 and an anti-detachment portion 14 connected to each other, the body 2 is provided with a connecting portion 23, the necking portion 13 is engaged with the connecting portion 23, and the anti-detachment portion 14 is provided on the inner side of the connecting portion 23 to prevent the hanger 1 from detaching from the body 2.

[0034] For ease of manufacturing, the anti-detachment part 14 is constructed as a spherical structure, and the neck portion 13 is constructed as a columnar structure. The outer diameter of the anti-detachment part 14 is larger than the outer diameter of the neck portion 13. Therefore, after the neck portion 13 is engaged with the connecting part 23, the anti-detachment part 14 cannot detach from the connecting part 23, thereby ensuring a safe and reliable connection between the pendant 1 and the main body 2.

[0035] Furthermore, a connecting rod 12 is provided between the first end of the hanger 1 and the second end of the hanger 1 . The connecting rod 12 is connected to the neck portion 13 . The outer diameter of the connecting rod 12 is greater than the outer diameter of the neck portion 13 .

[0036] Optionally, at least a portion of the connecting rod 12 is disposed in the connecting portion 23. Optionally, the connecting rod 12 is disposed entirely outside the connecting portion 23.

[0037] In some specific embodiments, the connecting portion 23 includes a mounting hole 231 and a slot 232 arranged inside the mounting hole 231, and the neck portion 13 passes through the mounting hole 231 and engages with the slot 232; the anti-detachment portion 14 is arranged on the inside of the slot 232, and the outer diameter of the anti-detachment portion 14 is smaller than the inner diameter of the mounting hole 231 and larger than the width of the slot 232. In other words, the anti-detachment portion 14 cannot extend from the slot 232, thereby preventing the pendant 1 from detaching from the main body 2.

[0038] The outer diameter of the necking portion 13 is smaller than the outer diameter of the connecting rod 12, and the outer diameter of the connecting rod 12 is smaller than the outer diameter of the anti-detachment portion 14, and the outer diameter of the anti-detachment portion 14 is much smaller than the outer diameter of the annular structure 11. In other words, the outer diameter of the necking portion 13 is the smallest, so when the necking portion 13 is exactly engaged and connected with the slot 232, the remaining parts of the pendant 1 can no longer escape from the slot 232.

[0039] In addition, the two ends of the neck portion 13 are connected to the connecting rod 12 and the anti-slip portion 14 through smooth surfaces, such as Figure 3 shown.

[0040] In some specific embodiments, in order to facilitate manufacturing, the body 2 is constructed as a split structure. Specifically, the body 2 includes a first shell 21 and a second shell 22 that are engaged with each other, the mounting hole 231 is provided on the side wall of the second shell 22, the slot 232 is provided on the inner wall of the first shell 21, and when the first shell 21 is covered on the second shell 22, the slot 232 is located on the inner side of the mounting hole 231.

[0041] Since the outer diameter of the anti-slip portion 14 is smaller than the inner diameter of the mounting hole 231, the anti-slip portion 14 and the neck portion 13 can extend into the mounting hole 231 and into the interior of the second shell 22. At this time, the first shell 21 is covered on the second shell 22, and the slot 232 is inserted into the neck portion 13. Since the outer diameter of the anti-slip portion 14 is larger than the width of the slot 232, the anti-slip portion 14 is blocked on the inner side of the slot 232 (i.e., inside the second shell 22) and can no longer extend out of the mounting hole 231.

[0042] Furthermore, for ease of manufacturing, the slot 232 is a U-shaped slot, with the open side of the U-shaped slot facing the second shell 22, so that the U-shaped slot and the second shell 22 form an approximate closed loop, thereby restricting the anti-detachment portion 14 to the inside of the second shell 22 to prevent the pendant 1 from escaping.

[0043] At least a portion of the inner wall of the U-shaped slot fits with the outer wall of the neck portion 13. When the first shell 21 is covered on the second shell 22, the U-shaped slot can clamp the neck portion 13 through its open side, and a portion of the inner wall of the U-shaped slot fits with a portion of the outer wall of the neck portion 13, so that the two are engaged with each other. When the U-shaped slot can clamp the neck portion 13 through its open side, the anti-slip portion 14 and the connecting rod 12 are isolated on both sides thereof, and the anti-slip portion 14 cannot cross the U-shaped slot, and similarly, the connecting rod 12 cannot cross the U-shaped slot, thereby ensuring a stable connection between the pendant 1 and the body 2.

[0044] In addition, the outer diameter of the annular structure 11 is larger than the inner diameter of the mounting hole 231 , so that the annular structure 11 cannot enter the interior of the switch body 2 through the mounting hole 231 .

[0045] In order to facilitate and quickly connect the first shell 21 and the second shell 22, as shown in FIG. Figure 1 As shown, one of the first shell 21 and the second shell 22 is provided with a buckle 211, and the other is provided with a slot 221, and the buckle 211 and the slot 221 match each other. Figure 1 In the illustrated embodiment, buckles 211 are provided on the first housing 21, and the buckles 211 are provided at equal intervals along the inner edge of the first housing 21. A clamping groove 221 is provided on the inner wall of the second housing 22, and when the first housing 21 is covered on the second housing 22, the buckles 211 and the clamping groove 221 are clamped and connected to form a whole.

[0046] The method for connecting the pendant 1 and the body 2 of the present invention is as follows:

[0047] First, the anti-dropping portion 14 and the shrinking portion 13 of the hanging component 1 are extended into the interior of the second housing 22 through the mounting hole 231 , and a portion of the connecting rod 12 is disposed in the mounting hole 231 .

[0048] Next, the first housing 21 is covered on the second housing 22 , so that the slot 232 clamps the constricted portion 13 through its open side, thereby restricting the anti-detachment portion 14 to the inner side of the slot 232 .

[0049] Finally, by pressing the first shell 21, the buckle 211 is engaged with the slot 221, so that the first shell 21 and the second shell 22 form a whole, and the anti-detachment part 14 is restricted to the inside of the second shell 22, and the annular structure 11 is restricted to the outside of the second shell 22 for easy carrying.

[0050] When in use, the user can tie a soft rope, a belt, etc. on the ring structure 11, and then wear the body 2 on the chest or on a key ring, etc., which is convenient for carrying.

[0051] In the second embodiment of the present invention, the hanger 1 is constructed as a split structure. Specifically, on the basis of the above-mentioned first embodiment, the anti-slip part 14 is assembled and connected with the neck part 13. For example, the anti-slip part 14 and the neck part 13 are connected by threads.

[0052] Therefore, there is no need to set the slot 232 on the first shell 21 . It is only necessary to set the outer diameter of the anti-detachment part 14 to be larger than the inner diameter of the mounting hole 231 and the outer diameter of the necking part 13 to be smaller than the inner diameter of the mounting hole 231 .

[0053] During installation, the anti-detachment part 14 is first separated from the shrinking neck part 13, and the anti-detachment part 14 is placed inside the second shell 22. After the shrinking neck part 13 passes through the mounting hole 231, the anti-detachment part 14 is connected to the shrinking neck part 13. Since the outer diameter of the anti-detachment part 14 is larger than the inner diameter of the mounting hole 231, the anti-detachment part 14 can be restricted inside the second shell 22 and cannot fall out of the mounting hole 231.

[0054] This embodiment only describes the differences from the first embodiment, and the same components and structures are not described again.

[0055] In the third embodiment of the present invention, the hanger 1 is constructed as an integrated structure. Its structural form is the same as that of the first embodiment, but different from the first embodiment in that the slot 232 is arranged in the mounting hole 231 and is movably connected to the mounting hole 231. For example, a spring is arranged in the slot 232. When the spring is in an extended state, the slot 232 is away from the mounting hole 231, so that the inner diameter of the mounting hole 231 that allows the neck portion 13 to extend is d1; when the spring is in a compressed state, the slot 232 is radially inserted into the mounting hole 231 and partially covers the mounting hole 231 in the radial section. At this time, the inner diameter of the mounting hole 231 is reduced, and the inner diameter that allows the neck portion 13 to extend is d2, wherein d2<d1, and d2 is smaller than the outer diameter of the anti-slip portion 14, and d1 is larger than the outer diameter of the anti-slip portion 14.

[0056] Through the above-mentioned setting method, when installing the hanger 1, the slot 232 can be moved away from the mounting hole 231, so that the inner diameter of the mounting hole 231 is d1, so that the shrinkage neck 13 and the anti-detachment part 14 can be extended into the mounting hole 231; then the slot 232 is radially inserted into the mounting hole 231 to reduce the inner diameter of the mounting hole 231, and its inner diameter becomes d2, then the anti-detachment part 14 cannot extend from the mounting hole 231, thereby limiting the anti-detachment part 14 to the inner side of the slot 232, that is, in the second shell 22.

[0057] This embodiment only describes the differences from the first embodiment, and the same components and structures are not described again.

[0058] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
