Problems solved by technology

With this design, if you want to change the insertion force, you can only redesign the design length and thickness of the female terminal: for example, increase the length of the female terminal and reduce the thickness of the female terminal → reduce the insertion force; increasing the length of the female terminal must Increasing the usage of copper tape will indirectly increase the manufacturing cost of the connector; although reducing the thickness of the female terminal can reduce the usage of copper tape, it will greatly reduce the number of plugging and unplugging of the female terminal, and it is not conducive to the female terminal. stable performance
[0004] On the other hand, the female terminal connector with the above structure has complicated processing technology and high price

Embodiment 1

[0027] Such as Figure 1-3 As shown, this embodiment discloses an in-line connection terminal, including a sleeve 2, the sleeve 2 is a copper sleeve with a cylindrical structure, one end of the sleeve 2 is provided with an annular end cap 4, and the sleeve 2 The inner axis is pierced with an annular elastic socket 6 for direct insertion of the adapter terminal. In the technical solution of this embodiment, the annular elastic socket 6 is formed by rolling a rectangular conductive shrapnel (preferably copper strip) and has a cylindrical structure. The annular elastic socket 6 of cylindrical structure is axially penetrated in the above-mentioned sleeve 2 . In the technical solution of this embodiment, the cylinder radius of the annular elastic socket 6 is designed to be slightly smaller than the cylinder radius of the sleeve 2. During assembly, the annular elastic socket 6 can be inserted into the sleeve 2 without deformation or damage to the entire circle, which is easy Assemb...

Embodiment 2

[0035] Such as Figure 4-6 As shown, this embodiment discloses an in-line connection terminal, and the difference between the second embodiment and the first embodiment is only that the fixing methods of the end cap 4 and the sleeve 2 are different.

[0036] In this embodiment, the above-mentioned end cap 4 is made of sheet metal, which is fixed on the end of the sleeve 2 by clamping and fixing; specifically, the outer wall of the above-mentioned sleeve 2 is provided with an annular groove 10, and the above-mentioned end cap 4 A second jaw 12 for clamping the wall of the annular groove 10 is provided on the top, and the end cover 4 is fixed on the end of the sleeve 2 through the second jaw 12 . In order to stably clamp and fix the end cap 4 and to limit the rotation of the end cap 4 after being fixed, the above-mentioned second clamping jaws 12 have a plurality of ring-shaped arrays, such as 2-10, or even more.

[0037] After the end cap 4 is fixed on the sleeve 2, the first ...

Abstract

The invention discloses a plug-type connection pin. The plug-type connection pin comprises a sleeve. One end of the sleeve is provided with an annular end cover. The sleeve is internally and axially provided with an annular elastic socket matched with the plug-type pin. One end, axially extended, of the annular elastic socket is clamped between the end cover and the sleeve, and the other axially extended end is freely deformed. According to the design of the plug-type connection pin, one end of the annular elastic socket is fixed, and the other end is freely deformed. In the process of inserting a plug in the annular elastic socket, a part of the radial resisting pressure applied to the plug by the annular elastic socket is converted to an axial deformation force of the annular elastic socket, so an insertion and extraction force generated in the matching process with the plug is reduced, the using performance and the insertion and extraction frequency of a connector are not affected, the manufacturing cost is reduced, the processing technology is simple, the contacting resistance is small, the precision is high, and the plug-type connection pin is suitable for the large-scale production.

Description

technical field [0001] The invention relates to a connection terminal, in particular to an in-line connection terminal for matching cable connection. Background technique [0002] Connectors (or connecting terminals) are used to connect two active devices and transmit current or signals. According to the plugging and unplugging of the connectors, there are two types of connectors, one is a plug and the other is a socket (or female terminal connector ); according to the size of the transmission current, there are two types of connectors, one is a connector suitable for small current transmission, and the other is a connector suitable for large current transmission. At present, the common structure of female terminal connectors suitable for large current transmission includes: copper sleeve and female terminal (also called torsion spring) arranged inside the copper sleeve, and the female terminal adopts a conductive shrapnel (also called reed) coil with a rectangular structure...
