Description

Technical Field

[0001] The utility model relates to a data line manufacturing technology in the technical field of data transmission, in particular to a one-to-many micro switch terminal line. Background Art

[0002] Terminal strips are insulating components used to connect multiple or multiple groups of mutually insulated terminal components and to fix supporting parts. They are mainly used to connect the lines of devices inside the screen and devices outside the screen to play the role of signal transmission. Terminal strips are widely used in electrical wiring, home decoration, electronic production, etc. Reasonable setting of terminal strips can make the connection between wires more firm and reliable, avoiding safety hazards such as poor contact and short circuit of wires.

[0003] Terminal strips usually include a wire body and terminals. In order to achieve multi-component connection, the terminal strips usually have several branch wires on the wire body, and different terminals or electrical components are connected to the branch wire ends. For example, some terminal strips will connect multiple micro switches at the branch wire ends, so that the micro switches can be connected directly or indirectly to the control unit through the terminal strips. The branch wires connecting the micro switches usually only require two single wires. Therefore, when connecting the micro switches, the number of branch wires connected to a single terminal strip is usually large; due to the large number of branch wires, it is not suitable to set a complex branch wire structure at the branch wire position of the terminal strip, so the branch wire portion has certain strength defects. When used for a long time or subjected to a large pulling force, the branch wire connection part at the branch wire position will be damaged, resulting in unstable or lost local data transmission, affecting the use effect of the entire terminal strip, and even causing circuit failure in severe cases.

[0004] Therefore, how to design a one-to-many micro switch terminal line with compact structure, reasonable layout, easy installation and maintenance has become an urgent problem to be solved in the current terminal line manufacturing technology. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1 A preferred embodiment of a one-to-many micro switch terminal wire, the multi-micro switch terminal wire of this embodiment includes a main wire 4, which is formed by a plurality of single wires, each single wire includes a conductor core and an insulating layer covering the conductor core, and the thickness of the insulating layer is controlled between 0.3mm and 1mm, ensuring the insulation performance of the wire body while maintaining good flexibility.

[0023] One end of the main line 4 is connected to the external device through a main line connector (not shown in the figure). The main line connector is a phosphor copper tinned terminal encapsulated in a plastic shell, and a potting groove is reserved at the connection with the main line 4. In actual operation, after the connection between the main line and the main line connector is completed, the potting groove is filled and potted with UV glue to enhance the stability and durability of the connector. The other end of the main line 4 is provided with a branching part, which realizes the branching and fixing of the micro switch sub-line 8 through a plastic ring.

[0024] In this embodiment, the plastic ring sleeve has a funnel-shaped branch line guide portion 5, and the branch line guide portion 5 is integrally formed with a sleeve connection portion 3 on the small mouth side of the funnel shape. Through the sleeve connection portion 3, the plastic ring sleeve can be tightly fitted and glued to the main line 4 to avoid sliding or falling off during use. The outer end of the flared side of the branch line guide portion 5 is formed with an elastic material ring 6, and the elastic material ring 6 is used to maintain the contour of the flared side of the plastic ring sleeve to ensure that the separated micro switch sub-line 8 can maintain a stable shape and position. The main line is separated into three groups of micro switch sub-lines 8 through the flared side of the branch line guide portion 5. Each group of micro switch sub-lines 8 includes two matching single lines. Each group of micro switch sub-lines 8 is equipped with a micro switch 9 at the outer end through these two single lines. The micro switch 9 is driven by an electrical signal to achieve the closing or opening function of the switch.

[0027] A heat shrink tube 2 is sleeved on the outer tube surface of the plastic ring sleeve, and the two ends of the heat shrink tube 2 respectively wrap the two ends of the plastic ring sleeve to ensure a tighter connection between the plastic ring sleeve and the main line 4. In particular, a rubber ring 7 is fixedly sleeved on the surface of the heat shrink tube 2 on the outer side of the expanded side of the plastic ring sleeve. The setting of the rubber ring 7 further enhances the structural strength of the branch line part and can improve the support and protection ability of the branch line part for the micro switch sub-line 8 through its own material properties.

[0028] In this embodiment, in order to further improve the protection performance of the terminal line, an outer protective layer 1 is formed on the line body part of the main line 4 between the main line connector and the branch line part. The outer protective layer 1 is made of a yellow wax tube or an outer nylon fabric layer to resist erosion and wear from the external environment during use and extend the service life of the main line 4 in the terminal line.
