Novel RF connector

Abstract

The invention discloses a novel RF connector and relates to a RF connector. The inner conductor and the outer conductor of the port of a conventional split RF connector are movably connected, and theconventional split RF connector has many components, resulting in multiple electrical contact surfaces so as to cause difficulty in the improvement of an intermodulation index. The novel RF connectorcomprises a main body; the main body is an integrated structure; the two ends of the main body are provided with a first connecting end and a second connecting end respectively; the first connecting end is connected with a feed line; the second connecting end is connected with a feed line or device panel. A conventional pin connector and a conventional jack connector are integrated into the main body so as to reduce the two electrical contact surfaces formed by the connection of the inner conductor and the outer conductor of the conventional pin connector and the conventional jack connector, thereby improving the intermodulation index of a communication system. The intermodulation index the communication system using a large number of RF connectors is improved obviously.

Description

technical field [0001] The invention relates to a radio frequency connector, in particular to a novel radio frequency connector. Background technique [0002] Radio frequency connectors are widely used in the field of wireless communication and are the basic components of a wireless communication system; they are generally installed on feeders and equipment panels to transmit radio frequency signals as electrical connections between feeders and equipment (or between feeders and feeders) or broken components. [0003] Traditional RF connectors are separate connectors, which need to be matched in pairs to complete the RF connection. The RF connection cannot be completed independently, that is, the pin-type RF connector and the jack-type RF connector with the same port type are paired to complete the connection. [0004] Traditional RF connectors are divided into two types according to the port form, pin type and jack type. [0005] The common port models of traditional RF co...

Problems solved by technology

[0009] Problems with traditional split RF connectors: Since the appearance of traditional split RF connectors in the 1930s, they have been using split (pin and jack mating) connections, mainly because of the measurement It is convenient for connection and disconnection when working or transferring signals, but in most other applications (such as engineering applications), frequent connection and disconnection are not required; It has little effect when it is small, but in the case of a large number of radio frequency signals in today's communication system, in order to avoid intermodulation interference, the intermodulation index of the communication system is very high, but the communication system using separate radio frequency connectors is very difficult. Difficult to obtain high intermodulation index

[0010] For example, there are multiple operators in the current mobile communication industry, and each operator has multiple mobile communication signals such as 2G, 3G, and 4G. Now many communication systems such as subway signal coverage need to combine these mobile communication signals, but the combination Afterwards, intermodulation interference problems generally exist, and the problems are mainly concentrated on the RF connector; because the RF connector is the most important factor affecting the intermodulation index of this type of communication system, the internal structure of the traditional separated RF connector, A lot of optimizations have been made in terms of component shape, component accuracy, etc., so that the intermodulation index of a single RF connector (pin type or jack type) can be achieved very well, but after it is used in a communication system, it is found that the entire communication The system intermodulation index still cannot be significantly improved

[0011] After a lot of theoretical and experimental research, we found that the root cause of this problem is that the inner conductor (jack and pin) and the outer conductor of the port of the traditional separated RF connector are all active connections, and there are many parts, resulting in electrical contact surface. Many lead to difficulties in improving the intermodulation index; traditional separate RF connectors mainly have the following problems:

[0016] 5. High production cost: The plugs and sockets of traditional radio frequency connectors require many parts such as shells, connecting nuts, pins, jacks, etc., and these parts need fine and complicated processing in order to cooperate with each other, so not only are there many parts but also Complicated processing and high production costs

[0017] 6. There are too many standards and models of traditional separated RF connectors, which complicates the application: because there are many types of RF feeders, there are also many types of RF connector ports, and the ports are divided into pin type and jack type, so it leads to There are many types of traditional separate RF connectors, which are prone to confusion during the application process, which is not conducive to large-scale engineering applications
