Description

Technical Field

[0001] The utility model relates to the technical field of wireless Jacquard textile, in particular to a connecting device for electrically connecting a piezoelectric Jacquard. Background Art

[0002] The existing piezoelectric Jacquard is installed on a comb. The driving circuit board on the piezoelectric Jacquard needle needs to connect the electrical signal to the circuit base plate on the comb. Usually, the spring needle method is used for connection. Since the internal components of the spring needle are composed of a spring, a top head, and a round tube, these three components are not an integral body but are mutually cooperating moving parts, having a certain resistance value and relatively poor electrical conductivity characteristics. Moreover, due to the small volume of the piezoelectric Jacquard needle and the large volume of the spring needle, and the high cost of the spring needle, the installation is troublesome. It needs to be installed and manually welded one by one, and only single-contact transmission for each signal can be adopted, which brings great risks to the poor contact of the electrical conductivity of the driving board on the piezoelectric Jacquard needle. There is still a need in this technical field for a more reliable connection method for providing electrical signals to the driving board of the piezoelectric Jacquard. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a connecting device for electrically connecting a piezoelectric Jacquard to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A connecting device for electrically connecting a piezoelectric Jacquard, including a shrapnel connector assembly, characterized in that: a comb is arranged at the bottom of the shrapnel connector assembly, a circuit board is installed on the top of the comb, a needle board is arranged at the top of the shrapnel connector assembly, a piezoelectric ceramic sheet is arranged near the front end of the top of the needle board, a driving board bin is arranged near the end of the top of the needle board, and a driving board is installed inside the driving board bin.

[0005] Preferably, a whole shrapnel assembly is arranged at the bottom of the shrapnel connector assembly, a plurality of shrapnels are arranged on both sides of the whole shrapnel assembly, and a circuit board is arranged at the top of the whole shrapnel assembly.

[0006] Preferably, the whole shrapnel assembly is mounted on the circuit board by an SMD mounter.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0008] 1. For the connecting device for electrically connecting a piezoelectric Jacquard, each shrapnel component for transmitting electrical signals is an integral component, having a small resistance value and strong electrical signal transmission. In addition, because the volume of the shrapnel can be very small, two shrapnels can be used for transmitting each signal, increasing the stability. Since the shrapnel component is an integral component, it can be installed as a whole, which is very convenient.

[0009] 2. The connection device for accessing the piezoelectric jacquard with the electrical signal uses a shrapnel assembly as the electrical signal access to the jacquard needle. The connection method of contacting the circuit board through multiple shrapnels is more reliable than the spring needle, and the overall installation cost is very low. Description of the Drawings
