Connectors are an indispensable component in electronic equipment. If you follow the path of current flow, you will always find one or more connectors. Connectors need to be welded with core wires when assembled. In the current electronics industry, especially in some products, the requirements for performance are getting higher and higher, and the requirements for the transmission of high-frequency signals are getting higher and higher. However, the demand for the quantity of some products in some industries is not large and the types are complicated, but the performance requirements are very high. Therefore, there is a problem of a wide variety of products and small quantities in the manufacturing process, which brings great troubles to enterprises in purchasing raw materials and manufacturing.

[0016] The present invention provides a connector welding fixture having the following beneficial effects:

[0017] 1. When using the connector welding fixture, place the connector to be welded on the clamping base, support the connector with the clamping airbag, and then rotate the clamping top seat, the clamping top seat drives the clamping plate thereon to rotate, the clamping plate drives the clamping airbag thereon to rotate and press it on the connector, and fix the clamping base and the clamping top seat together with the fixing buckle to clamp the connector.

[0018] 2. The connector welding fixture, when the connector is clamped by the clamping base and the clamping top seat, as the clamping top seat rotates, the card plate is driven gradually close to the connector. When the card plate contacts the connector, the connector will squeeze the card plate, causing the card plate to slide on the clamping base and the clamping top seat and squeeze the compression spring. After the clamping base and the clamping top seat clamp and fix the connector, the card plate is pressed against the surface of the connector under the pressure of the compression spring. The connector can be limited by the uneven shape of the connector surface and the card plate, thereby avoiding the sliding of the connector after clamping and fixing, resulting in inaccurate positioning, and having good stability in use.

[0019] 3. The connector welding fixture is provided with a positioning device. When placing the connector, the cable to be welded is placed on the supporting base at the same time. The clamping top seat will drive the positioning top seat to rotate when it rotates. The positioning top seat drives the supporting top seat to rotate through the arc spring, and presses the supporting top seat onto the cable to be welded. The cable can be clamped by the cooperation of the supporting base and the supporting top seat, so that there is no need to manually hold the cable for welding during welding, which is convenient to use. At the same time, the rotating circle can be rotated, and the rotating circle can move on the vertical rod under the push of the thread, thereby driving the support ring to move, the support ring drives the support plate to move, and the support plate drives the support base to move, so that the position of the cable can be changed by moving the support base, so that the cable can be adjusted after being fixed, so that the cable can be accurately connected with the connector, so that the welding effect is better.

[0020] 4. For the connector welding fixture, the smoke generated during the welding process is drawn into the inside of the nozzle through the air inlet on the nozzle, and then enters the filter box through the air pipe. The smoke can be filtered through the filter ball shell during the movement inside the filter box, and the filtered smoke can be discharged through the fan. During the filtering process, the filter ball shell can be driven to rotate by the rotating motor, and the part of the filter ball shell that filters the smoke is rotated to the side of the cleaning brush, and the cleaning brush can be driven to rotate by the cleaning motor, so that the filter ball shell can be cleaned by the cleaning brush to avoid blockage caused by long-term use and reduce the purification efficiency. There is no need for manual cleaning, and it is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
