[0029] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0031] The accompanying drawings are marked as follows: wire buckle K, shell 1, shell buckle 1a, shell slot 1b, assembly port 11, convex rib 12, assembly hole 13, notch 14, bipolar switch assembly 2, panel buckle 2a, anti-drop claw 2c, switch panel 21, bipolar switch 22, panel cover 23, socket module 3, socket buckle 3a, socket slot 3b, elastic claw 3c, clamp head 3d, wedge-shaped slope 3e, socket base 31, snap ring buckle 311, guide slope 312, electric sheet slot 313, socket panel 32, elastic snap ring 321, iron sealing plate 4, wire hole 4a, waist-shaped hole 41, power cord 5, electric sheet 6, N-pole conductive sheet 61, L-pole conductive sheet 62, E-pole grounding electric sheet 63, screw 7, partition 8, partition buckle 8a, partition slot 8b, partition claw 8c, trademark panel 9, side buckle 9a, side claw 9c.

[0032] In the prior art, there are already various PDU sockets on the market, but most of them are assembled with screws and the like. This assembly method is time-consuming and laborious, and the assembly efficiency is not high. The present invention provides a 10A national standard PDU socket, which is simple to assemble, convenient to operate, and saves labor and time. It includes a socket housing 1 made of aluminum alloy material, and a bipolar switch assembly 2 and a plurality of 10A national standard socket modules 3 arranged in a row in sequence in the housing 1. The housing 1 is a specially-made aluminum alloy profile with a "凵"-shaped cross-section, and its length can be intercepted according to the number of socket modules 3 to be installed. The housing 1 has an upper opening, a front end opening and a rear end opening. Iron sealing plates 4 are assembled at the front and rear end openings of the housing 1, namely the front port and the rear port, so as to seal the two ends of the housing 1 with the iron sealing plates 4. A power cord 5 for connecting to an external power supply is led out from the iron sealing plate 4 at the front port of the housing 1. The iron sealing plate 4 of the present invention has an inverted L structure, and three waist-shaped holes 41 are arranged side by side on the horizontal plate of the iron sealing plate 4. In this way, the user of the socket can use the waist-shaped holes 41 on the iron sealing plate 4 to hang or fix the PDU socket at a designated place. The main structures of the iron sealing plates 4 at the front and rear ends of the housing 1 are the same, except that a wire passing hole 4a is opened on the longitudinal plate of the iron sealing plate 4 installed at the front port of the housing 1, and the power cord 5 passes through the wire passing hole 4a. In order to prevent the power cord 5 from being pulled off during the use of the PDU socket, a wire clamp K is sleeved in the wire passing hole 4a, and the wire clamp K can hold and fix the passed power cord 5 so that it cannot move back and forth.

[0033] The greatest contribution of the present invention is that socket buckles 3a are formed on the upper ends of both sides of the socket module 3, and the socket buckles 3a extend outward and downward, so that a socket slot 3b with an opening downward is formed between the socket buckle 3a and the side wall of the socket module 1. In addition, two elastic claws 3c are formed on both sides of the socket module 3, which extend upward and can elastically stick to the side of the socket module under pressure. When not under pressure, the elastic claws 3c are just below the opening of the socket slot 3b. The two sides of the upper port of the shell 1 of the present invention are bent inward and downward to form an assembly port 11, and the two side walls of the assembly port 11 are formed with a shell buckle 1a for clamping into the socket slot 3b of the socket module 3. The shell buckle 1a is bent and extended upward, so that a shell slot 1b with an opening upward is formed between the shell buckle 1a and the side wall of the assembly port 11, and the shell slot 1b is used to clamp the socket buckle 3a of the socket module 3. In this way, the socket module 3 of the present invention can be fixed in the assembly opening 11 of the housing 1 by means of press-fitting by means of the mutual cooperation between the socket buckle 3a and the housing slot 1b and between the socket slot 3b and the housing buckle 1a, so that screws are not required for installation. During the installation of the socket module 3, the housing buckle 1a squeezes the elastic claw 3c to force the elastic claw 3c to stick to the side of the socket module and to clear the lower opening of the socket slot 3b. When the housing buckle 1a is inserted into the socket slot 3b, the elastic claw 3c is elastically reset. At this time, the clamping head 3d of the elastic claw 3c can cooperate with the anti-slip positioning of the bottom surface of the housing buckle 1a, thereby fixing the socket module 3.

[0034] In the embodiment, the socket module 3 of the present invention is a 10A national standard two-hole socket module, and the multiple socket modules 3 are positioned and connected as one through three electrical sheets 6 passing through the socket modules 3. Here, the present invention preferably has four 10A national standard two-hole socket modules mounted in the housing 1. That is to say, the four 10A national standard two-hole socket modules are positioned and connected as one through three electrical sheets 6. The three electrical sheets 6 include an N-pole conductive sheet 61, an L-pole conductive sheet 62, and an E-pole grounding electrical sheet 63 in sequence. The power cord 5 is a three-core power cord, and each electrical sheet is electrically connected to a corresponding wire in the power cord 5.

[0035] The socket module 3 of the present invention is composed of a socket base 31 and a socket panel 32 fixedly mounted on the socket base 31 by press assembly. The socket base 31 and the socket panel 32 are both injection molded from insulating flame-retardant materials, and the socket base 31 is formed with electrical chip slots 313 for positioning and clamping three electrical chips 6 passing through. The socket module 3 is formed by the socket base 31 and the socket panel 32, which is conducive to the installation of the electrical chips 6. The socket buckle 3a and the socket slot 3b of the present invention are both formed on the two sides of the socket panel 32, and the elastic claws 3c are formed on the two sides of the socket base 31.

[0036] By the present invention Figure 3 and Figure 6 It can be seen that two elastic snap rings 321 extending downward are formed on both sides of the socket panel 32 of the present invention. Correspondingly, two snap ring buckles 311 for snapping into the elastic snap rings 321 are formed on both sides of the socket base 31. The elastic snap ring 321 can be elastically deformed in a direction away from the side of the socket panel when squeezed by the snap ring buckle 311, so that the snap ring buckle 311 slides into the buckle hole of the elastic snap ring 321. In this way, the socket panel 32 and the socket base 31 can be connected into one body through the mutual cooperation of the elastic snap ring 321 and the snap ring buckle 311. It can be seen that when assembling the socket module 3 of the present invention, no screws are required, thereby maximizing the assembly speed of the PDU socket of the present invention.

[0037] In the embodiment Figure 1 and Figure 8 As shown, the bipolar switch assembly 2 of the present invention is also installed in the assembly opening 11 of the housing 1 by means of press assembly. The bipolar switch assembly 2 includes a switch panel 21 and a bipolar switch 22. The switch panel 21 is formed with a switch installation cavity for positioning and installing the bipolar switch 22. The bipolar switch 22 is installed in the switch installation cavity of the switch panel 21 by press assembly. The switch installation cavity has an upper opening. In order to prevent dust from entering the installation cavity and to improve the convenience of pressing the bipolar switch 22, a panel cover 23 for pressing the bipolar switch 22 is provided on the upper opening of the switch panel 21 so as to be able to slide up and down. In order to enable the bipolar switch assembly 2 to be assembled like the socket module 3, the bipolar switch assembly 2 can be assembled by pressing only, the two side surfaces of the switch panel 21 are also formed with panel buckles 2a for being inserted into the housing buckle slot 1b, and the panel buckle 2a and the side surface of the switch panel 21 are also formed with panel buckles with downward openings for the housing buckle 1a to be inserted into the matching panel buckle. In addition, the two sides of the switch panel 21 are formed with anti-dropout claws 2c for preventing the bipolar switch assembly 2 from dropping out after being mounted. The anti-dropout claws 2c can be forced to elastically deform and stick to the side of the switch panel under the pressure of the housing buckle 1a during assembly, and the anti-dropout claws 2c return to their original positions after losing pressure, and this original position just makes the anti-dropout claws 2c and the bottom surface of the housing buckle 1a form a positioning and anti-dropout structure.

[0038] In the embodiment Figure 2 As shown, a convex rib 12 is processed on the inner wall of the two sides of the housing 1 of the present invention, and a mounting hole 13 with a notch 14 is processed in the convex rib 12 along the axial direction. The function of the notch 14 is to allow the aperture of the mounting hole 13 to deform appropriately, thereby ensuring the tightness of the screw installation. The iron sealing plates 4 at the front and rear ports of the housing 1 are fixedly installed on the housing 1 through the screw 7 and the screw fit of the mounting hole 13.

[0039] In the embodiment, Figure 1 and Fig.11As shown, the present invention is provided with two partitions 8 between the iron sealing plate 4 and the socket module 3 installed at the rear port of the housing 1. The partitions 8 can prevent a gap from being generated between the iron sealing plate 4 and the socket module 3, thereby further ensuring that the socket module 3 will not be laterally displaced in the assembly opening 11. The partitions 8 of the present invention are also installed in the assembly opening 11 of the housing 1 by means of a press assembly. Fig.10 As shown, the two sides of the partition 8 are also formed with partition buckles 8a for being inserted into the housing buckle slot 1b, and the partition buckle 8a and the side of the partition 8 are also formed with a partition buckle slot 8b with an opening downward for the housing buckle 1a to be inserted, and the two sides of the partition 8 are also formed with partition claws 8c that can be elastically deformed under pressure and attached to the side of the partition, and the partition claws 8c cooperate with the bottom surface of the housing buckle 1a for anti-dropping positioning. The assembly principle of the partition 8, the bipolar switch assembly 2 and the socket module 3 are the same.

[0040] In the embodiment, a trademark panel 9 is provided between the iron sealing plate 4 installed at the front end of the housing 1 and the bipolar switch assembly 2. The trademark panel 9 is used to print the product trademark so that the user can understand the brand, power, operating voltage, etc. of the product. The trademark panel 9 of the present invention is also installed in the assembly port 11 of the housing 1 by pressing and assembling. Fig. 9 As shown, both sides of the trademark panel 9 are formed with side buckles 9a for snapping into the shell buckle 1b, and a side buckle slot with an opening downward for snapping the shell buckle 1a is formed between the side buckle 9a and the side of the trademark panel 9, and the two sides of the trademark panel 9 are also formed with side claws 9c that can elastically deform under pressure to stick to the side of the trademark panel, and the side claws 9c cooperate with the bottom surface of the shell buckle 1a to prevent disengagement and positioning.

[0041] In the embodiment, the bottom surface of the clamping head 3d of the elastic clamping claw 3c is formed with a wedge-shaped inclined surface 3e for sliding and pressing with the shell clamp 1a of the shell 1. The top surface of the clamping ring buckle 311 of the socket base 31 is a guide inclined surface 312 for facilitating the clamping ring buckle 311 to slide into the elastic clamping ring 321 of the socket panel 32. When the elastic clamping ring 321 is clamped, it is elastically deformed and stretched in the direction away from the side of the socket panel 32 by the support of the clamping ring buckle 311.

[0042] The PDU socket of the present invention is mainly composed of a shell 1, a bipolar switch component 2, a socket module 3, an iron sealing plate 4, a power cord 5, an electric sheet 6, a screw 7, a partition 8 and a trademark panel 9, wherein: the bipolar switch component 2, the socket module 3, the partition 8 and the trademark panel 9 are all installed in the assembly port 11 of the shell 1 by press assembly using the cooperation of the buckle and the card slot. The installation method is simple and convenient, easy to operate, labor-saving and time-saving, and thus can maximize the production efficiency of the socket. The shell is made of aluminum alloy, which is light in weight, good in strength, and has a strong metallic feel. The surface can also be made into various colors by electroplating, making the appearance of the socket more novel and beautiful.

[0043] The best embodiment of the present invention has been described, and various changes or modifications made by those skilled in the art will not depart from the scope of the present invention.
