Description

Signal transmission connector

technical field

The utility model relates to a signal transmission joint.

Background technique

Since the current telecommunication information is quite developed, and more and more consumer electronic products have the function of receiving signals, such as computers, televisions or radios, etc., the global information can be transmitted quickly. For the antenna device, it may be necessary to set up the signal transmission device to divide the signal into multiples during the process of transmitting the signal, so as to facilitate the use of multiple electronic products.

For example, a wave splitter is a signal transmission device. The wave splitter includes a transmission board with wires, a feed end (Transmission line feed point, transmission line feed point) and a ground end. Generally speaking, the feed-in terminal is located at the wire end of the transmission board, and the ground terminal is located at the opposite side of the transmission board with the wires. The feed-in end and the ground end can be connected to multiple cables by welding, so that the splitter has the function of dividing the signal into multiples. However, it is not easy to control the quality of soldering in such a cable connection method, which may result in poor signal transmission due to insufficient strength of the soldering point. In addition, the material of the transmission board must be a weldable material to weld the cable to the feed-in end and the ground end, causing inconvenience to the manufacturer.

Another way is to arrange signal transmission connectors (such as SMA antenna connectors) on the transmission board. However, the known signal transmission connectors also need to be soldered to the feed-in terminal and the ground terminal respectively, so the transmission board must still be a solderable material. , and the transmission board in this way needs to be a thicker hard board, which is more costly than softer and thinner materials. Furthermore, if the strength of the welding point between the signal transmission connector and the transmission board is insufficient, it will also cause poor signal transmission. On the other hand, the shell of the wave splitter only has the function of covering the transmission board, and has nothing to do with the signal transmission connector. The transmission board needs to be fixed in the shell with additional screws.

Therefore, the design of the signal transmission connector is a link that cannot be underestimated in the signal transmission equipment.
