Problems solved by technology

Terminals with such a width cannot meet the current requirements of electrical equipment and new energy vehicles that have higher and higher requirements for space saving.
[0004] Traditionally, in order to produce narrow-head terminals, people usually use cutting to narrow both sides of the connection part. The disadvantages of this production method are: 1. The two sides of the connection part after cutting are disconnected, resulting in a decrease in the strength of the connection part ; 2. The processing is very troublesome and the cost is very high

Embodiment 1

[0034] like Figure 1 to Figure 3 As shown, the narrow head terminal of the present invention is made of copper pipe, and its structure includes: a crimping part 1 and a connecting part 3, the crimping part 1 is cylindrical, and there is an inner cavity 2 in which a power supply wire or cable is inserted; The connecting portion is flat, and the upper and lower end faces are continuous on both sides, and a bolt hole 4 is provided in the middle. After the wire or cable is inserted into the inner cavity of the crimping part, the crimping part is clamped by the clamp, so that the wire or cable is fixed on the crimping part, and the bolt is set in the bolt hole of the connecting part to connect with the connection object .

[0035] Further, an excessive inclined surface 5 is formed between the crimping part and the connecting part, and an observation port 6 communicating with the inner cavity of the crimping part is provided on the inclined surface. The insertion position of the ...

Embodiment 2

[0037] like Figure 4-6 As shown, a method of producing the narrow-head terminal described in Example 1 of the present invention is taken as an example to produce a copper tube terminal suitable for wires or cables of 70 square meters, that is, the inner diameter of the crimping part is required d=13mm, and outer diameter D=17mm (that is, wall thickness=2mm). Before processing, select a copper tube with an inner diameter of 10mm and a wall thickness of 2-3mm (determined according to the compression ratio of the flaring device) for backup, and then complete the production through the following steps:

[0038] Step 1), pipe cutting: cut the copper pipe to the length required by the corresponding narrow-head terminal. Since the present invention uses two narrow-head terminals for simultaneous production, the copper pipe is cut into twice the corresponding narrow-head terminal, such as the production length L is a narrow head terminal of 57mm, and the length of the copper tube sh...

Abstract

The present invention discloses a narrow head terminal, a production method of the narrow head terminal and a special expanding device. The narrow head terminal comprises: a wire-pressing part, wherein the wire-pressing part is cylindrical, and the middle of the wire-pressing part is provided with an inner cavity used for inserting wire(s) or cable(s); and a connecting part, wherein the connectingpart is flat, the parts between both sides of the two end faces of the connecting part are continuous, and the middle of the connecting part is provided with a bolt hole. The narrow head terminal ischaracterized in that: an inclined plane with a transition part forms between the wire-pressing part and the connecting part, and the inclined plane is provided with a watching opening connected withthe inner cavity of the wire-pressing part, and the narrow head terminal is made of a copper tube. The narrow head terminal is produced by adopting the method of expanding both ends of the copper tubeingeniously. If a copper tube wire-connecting terminal suitable for the wire(s) or the cable(s) with 70 square meters is produced, the terminal can ensure smooth inserting of the wire(s) or the cable(s) with 70 square meters (d=13 mm), the requirement(s) of pressing connection are satisfied (D= 17 mm), and the width of the connecting part w is less than 24.4 mm (20 mm).

Description

technical field [0001] The invention relates to a connection terminal, in particular to a narrow head connection terminal. Background technique [0002] The structure of the connection terminal includes a crimping part and a connecting part, the crimping part is cylindrical, and there is an inner cavity in which a power supply wire or cable is inserted in the middle, and the connecting part is flat, and a bolt hole is provided in the middle. [0003] The width of the traditional terminal block is determined by the diameter of the copper tube after being flattened. The larger the diameter of the copper tube, the wider it will be after stamping. For example: to produce a copper tube terminal suitable for 70 square meters of wires or cables, the inner diameter d of the copper tube must generally be equal to 13mm to be able to penetrate the wire or cable smoothly, and its outer diameter D must generally be equal to 17mm (ie Wall thickness = 2mm) to ensure that the crimping part...
