Problems solved by technology

At present, the connectors of Siemens 8PT drawer cabinets can only be assembled manually by assembly workers. Because the assembly parts are small and many, two people are required to complete it together, and it is easy to be skewed. Due to assembly problems, there are many quality problems and rework, and once they cannot be checked. , there will be safety hazards for on-site users. Because one side of the connector is skewed and one side is in good contact and the other side is falsely connected, long-term use cannot meet the current carrying capacity requirements and heat will cause a fire accident. Therefore, the assembly of the 8PT drawer connector is very important.

Embodiment 1

[0036] Embodiment 1: 8PT drawer cabinets are assembled by single connectors at one time, refer to the attached Figure 4 , 7 , place the incoming and outgoing line bracket 4 in the rectangular hole of the mold body, use the bolt 7 with a flat pad to penetrate the installation hole of the copper clip 6, place it in the incoming and outgoing line bracket 4 and hold it with your hand; use the other hand to hold the copper The bench 3 and the copper right angle 2 are vertically put into the bracket 4 of the incoming and outgoing wires, and are set on the bolt 7 with a flat washer, and finally fastened with the nut 1 with a spring washer to ensure that the copper bench 3 and the copper right angle 2 are neatly installed. Skew, can not be skewed, and can not press the insulating material of the incoming and outgoing wire support when tightening, so that the copper bench 3 and the copper right angle 2 have a movable margin. After fastening, the incoming and outgoing wire support 4 is...

Embodiment 2

[0037] Embodiment 2: 8PT drawer cabinets are assembled in pairs of connectors at one time, refer to the attached Figure 5 , 8 , Place the incoming and outgoing line bracket 4 in the rectangular hole of the mold body, use the bolt 7 with a flat pad to penetrate the installation holes of the two copper clips 6, and the two copper clips 6 are arranged oppositely, and then place them in the incoming and outgoing line bracket 4 for use Hold it with your hand; use the other hand to vertically put a copper bench 3 and two copper right angles 2 into the bracket 4 of the incoming and outgoing wires, and put them on the bolts 7 with flat washers. The nut 1 with the flat spring washer is fastened to ensure that the copper bench 3 and the copper right angle 2 are installed neatly and not skewed, and the insulating material of the incoming and outgoing wire brackets cannot be pressed when tightened, so that the copper bench 3 and the copper right angle 2 have a movable margin After faste...

Embodiment 3

[0038] Embodiment 3: 8PT drawer cabinets are assembled in three connectors at one time, refer to the attached Image 6 , 9, Place the incoming and outgoing line bracket 4 in the rectangular hole of the mold body, and use the bolt 7 with a flat pad to penetrate the installation holes of the three copper clips 6, where two copper clips 6 are arranged overlapping and arranged opposite to the other copper clip 6 , the bolt 7 with a flat washer first penetrates two overlapping copper clips 6, and then penetrates another copper clip 6 that is oppositely arranged, and then places it in the incoming and outgoing wire bracket 4 and supports it with your hand; use the other hand to A copper bench 3 and two copper right angles 2 are put vertically into the incoming and outgoing line bracket 4, and they are set on the bolts 7 with flat washers. The two copper right angles 2 are overlapped, and finally fastened with nuts 1 with flat washers , to ensure that the copper bench 3 and the copp...

Abstract

The invention relates to a Siemens 8PT drawer cabinet primary connector assembly assembling method and a special die thereof, and belongs to the technical field of power distribution cabinet production. According to the technical scheme, an incoming and outgoing line support (4) is placed in a rectangular hole of a die body, a bolt with a flat gasket penetrates into an installation hole of a copper clamp (6), and the copper clamp (6) is placed in the incoming and outgoing line support (4) and is held by a hand; and the copper bench (3) and the copper right angle (2) are vertically placed in the wire inlet and outlet support (4) with the other hand, sleeved on the bolt (7) with the flat gasket and finally fastened by the nut (1) with the flat gasket and the elastic gasket, so that the copper bench (3) and the copper right angle are ensured to be mounted neatly and not to be inclined, and cannot press an insulating material of the wire inlet and outlet support during fastening, the copper bench and the copper right angle can have movement allowance, and after fastening, the wire inlet and outlet bracket is taken out from the die body (5). The invention has the beneficial effects that the special die is simple in structure and convenient to use, the assembling method is convenient to operate and accurate, time and labor are saved, and efficiency is improved.

Description

technical field [0001] The invention relates to a method for assembling a primary connector of a Siemens 8PT drawer cabinet and a special mold thereof, belonging to the technical field of power distribution cabinet production. Background technique [0002] Siemens 8PT drawer cabinet is a cabinet used to place high-end power distribution and control equipment, and it is a cabinet that is widely used at present. The primary plug-in of the 8PT drawer cabinet is the most important part of each drawer of the Siemens 8PT drawer cabinet. The primary plug-in is pulled out with the insertion of the drawer so that the electrical circuit of the drawer takes power from the vertical bus bar and supplies power to the outside. Its assembly requirements are very strict, the order must be correct, the assembly must be flat and not skewed, and there is a certain amount of activity in the hole of the incoming and outgoing wire bracket, and the edge of the bracket cannot be pressed so that the ...
