Description
Technical Field
The invention relates to the field of manufacturing and processing of mobile communication radio frequency equipment, in particular to radio frequency joint mounting equipment.
Background
In a mobile communication system, a large number of receiving and transmitting devices are concentrated in a base station with multi-channel operation, and if each receiving and transmitting device uses a pair of antennas, both of the same-pole erection and the separate-pole arrangement are not practical in the aspects of economy, technology, field utilization and the like, therefore, the antennas are widely used in mobile communication. Several transmitters share a set of transmit antennas, and such a shared device is called a transmit antenna combiner. Several receivers share a common receiving antenna, called a receiver antenna combiner. The combiner in the wireless mobile phone communication system is mainly used for combining the input signals of multiple frequency bands together and outputting the signals to the same indoor distribution system. The combiner is required to be capable of effectively feeding the output power of each transmitter to the antenna and avoiding the mutual influence between the transmitters, so that the requirement on the common device of the transmitting antennas is that the common device has good matching and high enough isolation.
In the prior art of the production and assembly of the combiner, an important part of the production steps are as follows: the radio frequency connector (such as DIN type connector) is first installed on the cavity of the combiner, and then the screw is used to tighten the radio frequency connector on the combiner. Through long-term practice, the installation state of each radio frequency connector on the assembled combiner has great difference, so that the index intermodulation of the combiner has great change. Furthermore, due to the fact that an assembly method is improper by an assembler, tightening force between the two devices is different, the contact surface of the platform on the cavity surface of the combiner and the platform of the radio frequency connector is difficult to fully contact, the assembly conditions of the radio frequency connectors on the interfaces of the assembled combiner are likely to be inconsistent, and the assembly conditions between different combiners are also different, so that intermodulation stability is greatly affected. Cross modulation, abbreviated as intermodulation, refers to the modulation of the carrier wave of useful signals by unwanted signals generated by interactions between signals in nonlinear equipment, networks or transmission coals, and in order to control combiner intermodulation, it is necessary to ensure that the radio frequency connectors mounted thereon are as consistent as possible to the design assembly requirements. However, the actual index generated by the current assembly process cannot meet the design product requirement, so that the product qualification rate is low, and the product quality is more difficult to improve. Similar situations also occur in other cavity devices where a radio frequency connector needs to be installed.

In order to more fully understand the radio frequency connector installation device provided by the invention, the invention takes a DIN type connector installation on a combiner as an example to describe in detail how to use the device, and the assembly and use method comprises the following steps:
step S100: the DIN-type connector is preloaded onto the cavity device. A combiner, which is one of the cavity devices, typically has three ports, two in ports at one end and one out port at the other end, with DIN-type connectors pre-assembled in a specific location of the combiner prior to fastening the connectors to the combiner.
Step S200: the DIN-type fitting is clamped with the cavity device so that both are in the mounting station. With the aforementioned DIN-type joint mounting apparatus, both are pressed onto a designed mounting station ready for fastening, the specific steps of which include:
step S210: the cavity device preloaded with DIN-type connectors is placed in a positioning frame, i.e., positioning mechanism 4200.
Step S220: the positions of the clamping device 3000 and the positioning mechanism 4200 are adjusted to match the DIN-type connector to the clamping device 3000 and to interface the DIN-type connector to the mounting location of the cavity device. The details of the fit of the DIN-type fitting to the clamping device 3000 are that the DIN-type fitting is placed into the fitting-matching recess 3100 such that the threaded holes on the DIN-type fitting correspond to the locations of the through holes 3200 on the clamping device 3000.

This process may be interpreted as placing the cavity device cavity into the DIN-type joint tightening assembly device, depressing the switch, and moving parts on the power unit push the top plate on the positioning and pressing device, driving the cavity device cavity and the DIN-type joint to be inserted upward into the clamping device 3000 and pressed, so that the cavity device cavity and the DIN-type joint can be pressed, stabilized and flattened, and the joint surface is in full contact with the mounting platform on the cavity device cavity surface.
Step S300: the DIN-type fitting is secured to the cavity device. The fastener may be tightened using a tightening tool, such as an air or electric screw. Preferably, the DIN-type joint is tightened in a particular sequence, specifically by tightening a pair of diagonally positioned screws first and then tightening another pair of diagonally positioned screws.
Experiments show that the mounting equipment can enable the radio frequency connector to be flatly pressed on the end face of the mounting hole of the cavity device, contact is more sufficient, the assembly precision and the product quality of the radio frequency connector and the cavity device are greatly improved, the stable improvement of intermodulation indexes is ensured, the former manual tightening intermodulation is about 145dBc, the tightening after the pressing is carried out by the mounting equipment, the intermodulation can reach 155dBc, namely, the intermodulation change amplitude of the radio frequency connector and the cavity device is more than 10 dBc.
