A power cord for a PDU as shown in fig. 1-5, comprising:

the power plug comprises a plug 1, wherein threading holes 11 are symmetrically formed in the plug 1, the end part of one end of the plug 1 is connected with an upper clamping plate 2 and a lower clamping plate 3, a protrusion 21 is arranged in the upper clamping plate 2, a first clamping groove 31 and a second clamping groove 32 are symmetrically formed in the lower clamping plate 3, a containing cavity 101 is formed between the upper clamping plate 2 and the lower clamping plate 3, a square groove 102 is formed between the first clamping groove 31 and the second clamping groove 32, a positioning screw hole 12 is formed in the power plug 1, the positioning screw hole 12 is located between the threading holes 11, the protrusion 21 is located in the containing cavity 101, and the square groove 102 is located outside the containing cavity 101;

one end of each of the electronic wires 4 is fixedly connected with a bolt 41, the other end of each of the electronic wires 4 is fixedly connected with a double-hole terminal 42, the bolts 41 on the electronic wires 4 respectively penetrate through the threading holes 11 and are clamped in the first clamping groove 31 and the second clamping groove 32 respectively, the end faces of the bolts 41 are in contact with the upper clamping plate 2, and a sleeve 5 is arranged at the contact part of the electronic wires 4 and the double-hole terminal 42.

In the technical scheme, when the socket is used, a plug is inserted into the socket matched with the socket, the protrusion 21 and the square groove 102 can be clamped with the socket in the plug inserting process, after the plug is inserted, the plug is fixed through the positioning screw hole 12, and then the double-hole terminal 42 is fixedly connected to the set position through a screw. Wherein, the bolt 41 of 4 tip of electron line contacts with last cardboard 2 to block each other with first draw-in groove 31 and second draw-in groove 32 respectively, guarantee that the bolt can be fixed between last cardboard 2 and lower cardboard 3, the through wires hole 11 that sets up on the plug can have limiting displacement to electron line 4, can protect the electron line simultaneously, prevent the crooked rupture of electron line, simultaneously, can effectually cut apart electron line 4, avoid electron line 4 to take place the touching.

In the above technical scheme, the width of the upper clamping plate 2 is slightly larger than the width of the lower clamping plate 3, and the upper clamping plate 2 is not in contact with the lower clamping plate 3. Adopt this kind of mode, the width of going up the cardboard slightly is greater than cardboard width down, and contactless each other for form the step face that is used for the block between last cardboard and the cardboard down, and can extrude at the in-process of inserting the plug, produce little deformation, make to connect inseparabler.

In the above technical solution, the engagement modes of the plug 41 with the first card slot 31 and the second card slot 32 respectively are as follows: the lower end surfaces of the bolts 41 are fixedly welded with top plates 6, and the end parts 61 of the top plates 6 are respectively clamped on the walls of the first clamping grooves 31 and the second clamping grooves 32. Adopt this kind of mode, the end fixing that is located the draw-in groove at the electronic wire sets up the roof, and make the roof integrated circuit board with on the lateral wall of draw-in groove, the tip of guaranteeing the electronic wire is spacing in the draw-in groove, and because the used repeatedly of plug, make the bolt can have certain deformation, lead to with socket contact failure, and the roof that sets up at the bolt lower extreme can jack-up the bolt, and at plug male in-process, because the bolt terminal surface is provided with the arch, make the bolt have decurrent pressure, the roof can produce certain compression capacity simultaneously, make the bolt deform downwards, make things convenient for the plug to insert, the plug inserts the back, resume the original state again, the bolt of the tip of assurance electronic wire can be abundant contradict each other with the inside electrically conductive bolt of socket.

In the above technical solution, the end surfaces of the plugs 41 are all provided with trapezoidal protrusions 411. By adopting the mode, the arranged trapezoidal bulges are used for abutting against the matched bulges in the socket, and the good contact of the contact parts is ensured.

In the above technical scheme, the sleeve 5 is a black heat-shrinkable sleeve with glue. By adopting the mode, the black glued heat-shrinkable tubing is used, the connecting part can be wrapped inside the tubing to prevent electric leakage, and the glued heat-shrinkable tubing is convenient to install and can be fully contacted with the electronic wire and the double-hollow terminal.

In the above technical solution, the end surface of the dual-hole terminal 42 is an inclined surface. By adopting the mode, the inclined plane of the double-hole terminal ensures that the contact area is large after the double-hole terminal is fixed by the screw, and the resistance of the contact part is reduced.

In the above technical scheme, the outer wall of the plug opposite to the threading hole 11 is provided with stripes 13. In this way, the strips are arranged to increase the friction between the hand and the plug when the plug is inserted.

In the above technical scheme, the upper clamping plate 2 and the lower clamping plate 3 are connected with the plug 1 in an integrated manner. By adopting the mode, the upper clamping plate and the lower clamping plate are integrally formed and connected, the connection strength is ensured, two symmetrical parts produced by inserting are integrated through the hot-press forming process, and the clamping electronic wire is convenient to mount.

The number of apparatuses and the scale of the process described here are intended to simplify the description of the present invention. Applications, modifications and variations of the power cord for PDU of the present invention will be apparent to those skilled in the art.

While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
