Technical Field

[0001] The present invention relates to the technical field of socket manufacturing, and particularly to a PDU socket. Background Art

[0002] A PDU socket is a new type of socket device. There is a PDU socket dedicated to network power supply. Through the connection between the network power plug and the PDU socket, power supply is provided for the network server. The network server has a huge amount of data being transmitted at all times, and the network server stores a vast amount of data. Therefore, it is necessary to ensure the reliability of the power supply to the network server to ensure its normal operation. In the prior art, a PDU socket usually consists of a housing and a socket module and a switch assembly installed in the housing. The socket module is assembled by screwing together a socket panel and a socket base. This assembly method using screws not only increases the cost of the screws, but also requires specific tools during assembly. Therefore, the assembly speed is slow and the efficiency is low. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a PDU socket with simple assembly, easy operation, fast speed, and high efficiency in view of the above-mentioned prior art status.

[0005] A PDU socket includes a long strip-shaped socket housing with a cross-section in a "U" shape, and a bipolar switch assembly and a plurality of socket modules arranged in a row and installed in the housing. A power cord for connecting to an external power supply is led out from the front end of the housing, and the power cord is electrically connected to three conductive sheets passing through the socket module. The socket module is an IEC C13 two-hole socket module assembled by snap-fit of a two-hole panel and a two-hole bottom plate. On the bottom surface of the two-hole panel, two pairs of downwardly extending elastic claws are symmetrically formed on the left and right. The bottom end of the elastic claw is designed with a buckle head facing outward. On both sides of the inner cavity bottom surface of the two-hole bottom plate, at positions opposite to the elastic claws, there are buckle grooves that can just enable the buckle head to be positioned and snapped in. On the inner walls of both sides of the two-hole bottom plate, inwardly directed clamping heads are formed above the buckle grooves. The clamping heads are cooperated with the buckle heads snapped into the buckle grooves to prevent the hook from disengaging, thereby realizing the snap-fit assembly between the two-hole panel and the two-hole bottom plate.

[0006] To optimize the above technical solution, the specific measures taken further include:

[0007] The bottom of the above-mentioned buckle head is formed with a smooth arc surface and a buckle head inclined surface connecting the arc surface. A guide protrusion is designed on the bottom surface of the inner cavity to facilitate the buckle head to slide into the buckle groove. The guide protrusion is formed with a guide inclined surface for sliding and guiding with the arc surface of the buckle head; the clamping head is formed with a wedge-shaped inclined surface for cooperating with the buckle head inclined surface to force the elastic claw to elastically deform inward.

[0008] The three conductive sheets include an L-pole conductive sheet, an N-pole conductive sheet and an E-pole grounding sheet; a plurality of socket modules are connected together through the three conductive sheets to form a socket module group; three electrical sheet slots are formed at the front and rear ends of the two-hole base plate for positioning and mounting the three conductive sheets passing through.

[0012] The above-mentioned rear iron sealing plate and the socket module gasket are equipped with a partition, which is installed in the assembly port of the shell by press-assembly. The two side surfaces of the partition are formed with partition buckles for being inserted into the shell slots. A partition slot with an opening downward for the shell buckle to be inserted is formed between the partition buckle and the side surface of the partition, and the two side surfaces of the partition are also formed with partition claws that can elastically deform and move inward under pressure, and the partition claws cooperate with the anti-slip positioning of the bottom surface of the shell buckle.

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

[0032] In the prior art, for various PDU sockets on the market, their socket modules are all assembled by screws or the like between the panel and the bottom plate. This assembly method is time-consuming and laborious, and the assembly efficiency is not high. The present invention provides a PDU socket here. This PDU socket is simple to assemble, convenient to operate, and saves labor and time. It includes a socket housing 1 that is long strip-shaped and has a "U"-shaped cross-section, and a double-pole switch assembly 2 and a plurality of socket modules 3 arranged in a row and installed in the housing 1. The housing 1 is made of aluminum alloy material. The aluminum alloy-made housing 1 is light in weight, good in strength, and strong in metallic feeling. Moreover, the surface of the housing 1 can also be electroplated into various colors, so that the appearance of the PDU socket can look more novel and beautiful as a whole. A power cord 4 for connecting to an external power supply is led out from the front end of the housing 1 of the PDU socket. The power cord 4 is a three-core power cord, and the three cores are distinguished by different colors. The three cores are respectively an L-pole wire, an N-pole wire, and an E-pole wiring. The three core wires in the power cord 1 are respectively electrically connected to three conductive sheets 5 passing through the socket module 3.

[0033] The greatest feature of the present invention is that the socket module 3 is an IEC C13 two-hole socket module assembled by the two-hole panel 31 and the two-hole bottom plate 32 in a snap-fit manner. The two-hole panel 31 and the two-hole bottom plate 32 are assembled in a snap-fit manner, and their assembly is simple and can be completed without any special tools. Therefore, as Figure 4 , Figure 5 and Figure 6As shown, the present invention has two pairs of elastic claws 311 extending downwards symmetrically formed on the bottom surface of the two-hole panel 31, each pair has two elastic claws 311, and a total of four elastic claws 311. The elastic claws 311 have a certain elasticity and can be elastically deformed outward or inward under the action of thrust. When the thrust is lost, the elastic claws 311 can restore their original state. The bottom end of the elastic claw 311 is designed with a buckle head 312 facing outward. Buckle grooves 321 that can just position and snap the buckle head 312 are opened on both sides of the bottom surface of the inner cavity of the two-hole bottom plate 32 at positions opposite to the elastic claws 311. The buckle grooves 321 can limit the displacement of the elastic claws 311 in the front, back, left and right directions. On the inner walls of the two side surfaces of the two-hole bottom plate 32, above the buckle groove 321, there are formed inwardly directed clamping heads 322, which can cooperate with the anti-detachment hooks of the buckle heads 312 inserted into the buckle groove 321, thereby realizing the snap-on assembly between the two-hole panel 31 and the two-hole bottom plate 32.

[0034] In order to ensure the smooth assembly of the two-hole panel 31 and the two-hole bottom plate 32, Figure 6 It can be seen that the bottom of the buckle head 312 is formed with a smooth arc surface A1 and a buckle head inclined surface B1 connecting the arc surface A1. A guide protrusion 323 is designed on the bottom surface of the inner cavity of the two-hole bottom plate 32, and a guide inclined surface A2 is formed on the guide protrusion 323, and a wedge-shaped inclined surface B2 is formed on the clamp head 322. When the two-hole panel 31 is pressed to assemble the two-hole panel 31 and the two-hole bottom plate 32, the buckle head inclined surface B1 of the buckle head 312 and the wedge-shaped inclined surface B2 on the clamp head 322 form a wedge structure, and the wedge-shaped inclined surface B2 can convert the downward pressure of the two-hole panel 31 into a thrust that pushes the elastic claw 311 to elastically deform inward horizontally, thereby forcing the buckle head 312 of the elastic claw 311 to slide over the clamp head 322 through the sliding fit between the buckle head inclined surface B1 and the wedge-shaped inclined surface B2. The guiding inclined surface A2 on the guiding protrusion 323 can cooperate with the arc surface A1 of the buckle head 312 for sliding guidance, so that the buckle head 312 of the elastic claw 311 can slide smoothly into the buckle groove 321 of the two-hole bottom plate 32.

[0035] In the embodiment Figure 1 As shown, the three conductive sheets 5 of the present invention include an L-pole conductive sheet 51, an N-pole conductive sheet 52 and an E-pole grounding sheet 53. A plurality of socket modules 3 are fixedly connected together by the three conductive sheets 5 to form an inseparable socket module group; three electrical sheet card slots 32a are respectively formed at the front and rear ends of the two-hole bottom plate 32, and the electrical sheet card slots 32a can position and card the passing conductive sheet 5 and prevent short circuit between two adjacent conductive sheets 5.

[0036] The socket module 3 of the present invention is mounted on the housing 1 by pressing. Figure 7 and Figure 8As shown, the two side surfaces of the housing 1 are bent inward and downward at the upper end so that the original upper end forms an assembly opening 1a, and the two side walls of the assembly opening 1a are formed with housing buckles 11 extending upward, and a housing buckle groove 12 opening upward is formed between the housing buckle 11 and the side wall of the assembly opening 1a. Figure 5 It can be seen that the upper plate surface of the two-hole panel 31 extends to both sides to form a convex edge, and the edge of the convex edge is formed with three sections of socket buckles 313 extending downward, and the socket buckles 313 are used to be inserted or snapped into the shell buckle 12 of the shell 1 during assembly. A socket buckle 314 for snapping the shell buckle 11 is formed between the socket buckle 313 and the side of the two-hole panel 31. In addition, a suspended anti-drop claw 315 is formed on the bottom surface of the convex edge between two adjacent socket buckles 313. The anti-drop claw 315 is not only set between the two socket buckles 313, but also closer to the side of the two-hole panel 31. When the anti-dropping claw 315 is pressed and assembled, it can be elastically attached to the side of the two-hole panel 31 under the thrust of the shell buckle 11; thereby, the socket module 3 can be assembled in the assembly port 1a of the shell 1 by press-assembly using the mutual cooperation between the socket buckle 313 and the shell slot 12 and the socket slot 314 and the shell buckle 11, and the claw head 316 of the anti-dropping claw 315 cooperates with the anti-dropping positioning of the bottom surface of the shell buckle 11.

[0037] like Figure 1 and Figure 8 As shown, a convex rib 13 with an assembly hole 1b is processed on the inner wall of the two side surfaces of the shell 1 of the present invention, and a long strip opening 1c connected to the assembly hole 1b is axially opened on the convex rib 13. The long strip opening 1c can cause the aperture of the assembly hole 1b to deform under the action of the screw, thereby ensuring the firmness of the connection. The front port of the shell 1 is fixedly installed with a front iron sealing plate 71 through the spiral cooperation of the screw 6 and the assembly hole 1b, and the rear port of the shell 1 is fixedly installed with a rear iron sealing plate 72 through the spiral cooperation of the screw 6 and the assembly hole 1b. The front iron sealing plate 71 and the rear iron sealing plate 72 are both inverted L-shaped structures, and waist-shaped holes 7a for convenient fixing or hanging of the PDU socket are opened on the horizontal plate of the front iron sealing plate 71 and the horizontal plate of the rear iron sealing plate 72.

[0038] In the embodiment, a wire hole 7b for passing the power cord 4 is opened on the longitudinal plate of the front iron sealing plate 71 of the present invention, and a wire buckle K for preventing the power cord 4 from being pulled off is fixedly mounted in the wire hole 7b, and the power cord 4 is sleeved in the wire buckle K.

[0039] In the embodiment, a partition plate 8 is provided between the rear iron sealing plate 72 and the socket module 3, and the partition plate 8 is also installed in the assembly opening 1a of the housing 1 by means of a press assembly. Fig.10It can be seen that partition buckles 81 for snapping into the outer shell buckle 12 are formed on both side surfaces of the partition 8, and a partition buckle slot 82 with an opening downward for snapping the outer shell buckle 11 is formed between the partition buckle 81 and the side surface of the partition 8, and partition claws 83 that can elastically deform and move inward under pressure are also formed on both side surfaces of the partition 8, and the partition claws 83 cooperate with the anti-slip positioning of the bottom surface of the outer shell buckle 11.

[0040] like Figure 2 As shown, the housing 1 of the present invention is also equipped with a trademark panel 9, which is used to print the product trademark so that users can understand the product brand, power, operating voltage, etc. The trademark panel 9 is also installed in the assembly port 1a of the housing 1 by pressing and assembling. Fig.11 As shown, both sides of the trademark panel 9 are formed with side buckles 91 for snapping into the shell buckle 12, and a side buckle slot with an opening downward for snapping the shell buckle 11 is formed between the side buckle 91 and the side of the trademark panel 9, and the two sides of the trademark panel 9 are also formed with side claws 93 extending downward and elastically deformable under pressure to stick to the side of the trademark panel, and the side claws 93 cooperate with the bottom surface of the shell buckle 11 to prevent it from falling off and positioning.

[0041] In the embodiment, Figure 2 As shown, the assembly opening 1a of the present invention is equipped with four socket modules 3. The trademark panel 9, the double-pole switch assembly 2 and the four socket modules 3 are arranged in sequence from front to back in the assembly opening.

[0042] like Fig.12 As shown, the bipolar switch assembly 2 of the present invention is also mounted in the assembly opening 1a of the housing 1 in a press-fit manner, and 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, and the bipolar switch 22 is mounted in the switch installation cavity of the switch panel 21 by snap-fitting. 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. The panel cover 23 is made of a transparent material. The switch panel 21 of the present invention is formed with panel clips 211 on both sides for being clipped into the housing clip slot 12, and a panel clip slot with an opening downward for the housing clip 11 to be clipped into is formed between the panel clip 211 and the side of the switch panel 21; the switch panel 21 is also formed with anti-drop claws 213 extending downward and being able to elastically deform and move inward under pressure on both sides; the anti-drop claws 213 cooperate with the anti-drop positioning of the bottom surface of the housing clip 11.

[0043] The advantages of the present invention are that the bipolar switch assembly 2, the socket module 3, the partition 8 and the trademark panel 9 are all installed in the assembly port 11 of the housing 1 by means of press assembly. At the same time, the socket module 3 is also assembled by means of a two-hole panel 31 and a two-hole bottom plate 32 by means of snap fit. Therefore, the PDU socket installation method of the present invention is simple and convenient, easy to operate, labor-saving and time-saving, and can maximize the production efficiency of the socket. The housing 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.
