Description

Technical Field

[0001] This utility model relates to the field of jacquards, and in particular to a wireless jacquard and a conductive device for the wireless jacquard. Background Technology

[0002] Wireless Jacquard refers to a device that integrates a driver inside the Jacquard comb. This driver can be used to drive the piezoelectric ceramic part inside the Jacquard comb to swing, thereby causing the yarn guide needle to swing together to achieve the jacquard yarn guiding action, and thus achieve the purpose of removing the cable on the tail of the Jacquard comb.

[0003] Chinese utility model patent (application number: 201520150649.1, publication number: CN204496248U) discloses an embedded electronic jacquard comb for jacquard control of warp knitting machines, but there are still shortcomings in actual use: at present, how to effectively realize electrical connection between the driver and the piezoelectric ceramic part is the key part restricting the development of wireless jacquard.

[0004] If the driver and piezoelectric ceramic part are directly connected by a ribbon cable, with the output end of the ribbon cable soldered to the power terminal of the piezoelectric ceramic part and the input end of the ribbon cable soldered to the output end of the driver, the space between the driver and the piezoelectric ceramic pieces is narrow due to the dense arrangement of multiple piezoelectric ceramic pieces. This makes it easy to solder the wrong position during the welding of the conductive contacts, which leads to processing difficulties. Utility Model Content

Its main purpose is to overcome the defects in the wireless jacquard, where a ribbon cable is used to electrically connect the driver and the piezoelectric ceramic part, the output end of the ribbon cable is soldered to the power receiving end of the piezoelectric ceramic part, and the input end of the ribbon cable is soldered to the output end of the driver.

When installed, the input terminal of the first conductive element is plugged into the output terminal of the second conductive element. When disassembled, the first conductive element is pulled out to separate the first conductive element from the second conductive element.

The conductive device 300 is provided on another part of the Jacquard yarn guide block 200.

[0025] Reference Figure 1 and Figure 2The output end of the conductive device 300 is soldered to the power terminal of the piezoelectric ceramic part 202, and the input end of the conductive device 300 is detachably mounted on the output end of the driver 301. In this embodiment, when a wireless Jacquard is used, the piezoelectric ceramic part 202 and the driver 301 are electrically connected through the conductive device 300.

On the other hand, by setting the second conductive elements 206 to adapt to the first conductive elements 205, the number of first conductive elements 205 is increased, thereby reducing the number of wires to be connected on each first conductive element 205, thereby reducing the processing difficulty and achieving a dual benefit.

When installed, the input terminal of the first conductive element 205 is plugged into the output terminal of the second conductive element 206.
