Embodiment 1

[0031] The structure of the flag-shaped terminal described in the present invention is shown in figure 2 As shown, it includes a cable connection part 1 and a wiring female terminal 2. The cable connecting part 1 is used for connecting cables, and generally includes a covering part 11 for wrapping the cable and a pressing part 12 for pressing the cable core. The female connection terminal 2 is used to connect a male connection terminal, such as a plug-in piece. In this embodiment, the connection direction of the cable connection part 1 is perpendicular to the connection direction of the connection female terminal 2 . The female terminal 2 includes a slot 21, the two sides of the slot 21 are arc-shaped tubular sidewalls 211, and the bottom of the slot 21 is formed with two longitudinal slits 212, such as figure 2 As shown, the width of the gap is set to 0.25mm. An elastic arm 213 is formed between the two slits 212, the length of the elastic arm 213 is 6mm, and the width i...

Embodiment 2

[0042] On the basis of the flag-shaped terminal described in Embodiment 1, a central extension 214 is further formed in the middle of the elastic arm 213, see image 3 , the width of the central expansion portion 214 is greater than the width of both ends of the elastic arm 213 . Here, the central expansion part 214 is circular and is disposed close to the notch of the slot 21 .

Embodiment 3

[0044] On the basis of the flag-shaped terminal described in the above embodiment, the inner wall of the arc-shaped tubular side wall 211 of the slot 21 is formed with a limited boss 3, see Figure 4 . The central expansion part 214 is provided with a locking protrusion 4, and the height of the locking protrusion 4 increases from one end close to the notch of the slot 21 to the other end, see image 3 .Such a structure has a smooth transition when inserting the male terminal, which is easy to insert, and has a groove structure when pulling out, so it is not easy to pull out, making the effect of low insertion force and high pull-out force more obvious. Further, at the bottom of the slot 21 and one end away from the notch of the slot 21, on the outer side of the elastic arm 213, a blocking protrusion 5 is provided, and the blocking protrusion 5 can limit the connection of the male terminal. depth, see image 3 .

Abstract

The invention relates to a flag-shaped terminal which comprises a cable connecting part and a wiring female terminal, wherein the wiring female terminal comprises a slot; arc tubular side walls are arranged on two sides of the slot; two longitudinal clearances are formed in the bottom of the slot; and an elastic arm is formed between the two clearances. According to the flag-shaped terminal, the technical problems of difficulty in realization of smaller inserting resistance and stable connection after inserting in the prior art are effectively avoided; and the flag-shaped terminal is a flag-shaped terminal with a low inserting force and a high extracting force.

Description

technical field [0001] The invention relates to a connection terminal, in particular to a flag-shaped terminal with low insertion force and high pull-out force, and belongs to the technical field of connection components and connectors. Background technique [0002] Terminal block is an accessory product used to realize electrical connection. It belongs to the category of connectors in industry and is widely used in electronic and electrical fields, such as ballasts, transformers, switching power supplies, instruments and meters, IT communications, alarm devices, and elevator equipment. , lighting, household appliances, etc. With the increasing degree of industrial automation and the increasingly strict and precise industrial requirements, higher requirements are put forward for the wiring flexibility and connection reliability of the terminal blocks. [0003] figure 1 A flag-shaped terminal in the prior art is provided, which is mainly used in electrical equipment such as...
