Description
Technical Field
The invention relates to an intersection finger-shaped positioning method mainly used for positioning a radio frequency connector group installed in an array.
Background
At present, microwave component modules develop towards miniaturization and integration, the equipment integration level is higher and higher, the number of electrical connections required on each module is greatly increased, and the blind-mate radio frequency coaxial connector array is more and more widely applied to microwave systems. The components and the modules are directly connected by adopting a miniaturized and large-scale blind-mate radio frequency coaxial connector array, and the connection mode becomes a common connection mode of microwave component modules. For example, preamplifiers, intermediate frequency amplifiers, double balanced mixers, directional couplers, switch matrix circuits, and even entire receivers may be connected using blind-mate connectors.
The module adopts a blind-mate connector structure form which is greatly different from that of a conventional radio frequency connector, and especially for a microwave assembly module with a gas tightness requirement, a blind-mate radio frequency coaxial connector array form which is formed by two groups of jacks (sockets) and a group of bidirectional plugs is generally adopted, as shown in fig. 6: large-scale radio frequency jack (socket) groups are arranged on the two interconnected moulds 1 and 2 in an array, and the electrical connection is realized by arrayed high-density bidirectional plugs in the middle. When the connector is matched, each blind-plugging bidirectional plug in the connector array is required to be aligned to a corresponding jack (socket), and the bidirectional plug needs to be accurately positioned before plugging, so that the blind-plugging bidirectional plug can be successfully plugged with a corresponding socket in the blind-plugging process, and the good overall connection can be ensured. For miniaturized, large array-scale rf connector sets, the connectors in the middle portion are difficult to manipulate by hand or by a tool, making alignment difficult. Especially, in the microwave module working in the high frequency band, the radio frequency blind-mate connector has high precision requirement on the interface size, the space position is very narrow, and if the positioning of the contact pin and the jack is not accurate, the performance can be seriously affected after the plugging. Although the traditional manual adjustment method can also be assembled, the alignment of all the bidirectional plugs is difficult to ensure, the loss of transmission signals after the two-way plugs are plugged is large, and even the connector can be damaged; meanwhile, a large operation space is needed, and the requirement of high-frequency equipment is difficult to meet.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a method which is convenient to operate, reliable in positioning and low in cost and can be used for integrally positioning a large-scale miniaturized high-density bidirectional plug array so as to solve the problem of positioning and assembling the large-scale connector high-density array.
The above object of the present invention can be achieved by the following measures: a radio frequency/microwave blind plugging connector array positioning method is characterized by comprising the following steps: before equipment assembly, preparing a finger-shaped clamp which can limit all radio frequency blind-mate connector array bidirectional plugs in two groups of positioning finger insertion plates in a crisscross insertion finger grid; during assembly, all array bidirectional plugs of the radio frequency blind-mate connector are inserted into the socket blind-mate jack of one microwave assembly module one by one to form a matrix of a radio frequency bidirectional plug array; inserting the longitudinal positioning finger inserting plate 1 and the transverse positioning finger inserting plate 2 into an array area of the radio frequency bidirectional plug from a longitudinal direction and a transverse direction in a staggered manner respectively, wherein a staggered grid is formed between matrix row-column spaced channels of the radio frequency bidirectional plug by a longitudinal group and a transverse group of vertically-stacked positioning fingers; then a right-angled square positioning piece 3 is used for fixing a rectangular right-angle side formed by the intersection of the longitudinal positioning finger inserting plate 1 and the transverse positioning finger inserting plate 2; and each hole in the grids of the two groups of positioning finger insertion plates is respectively attached to the outline of each radio frequency blind-mate connector bidirectional plug, and the relative plane positions of all the radio frequency bidirectional plugs are positioned by means of the matching of the sizes of the crossed grid holes and the external sizes of the connectors, so that the integral positioning of the high-density bidirectional plugs of the radio frequency blind-mate connector array between the microwave assemblies is completed.

The required positioning device has simple structure and convenient installation, can position all connectors in the array at one time in a narrow space, can compress the volume of a microwave system, improves the interchangeability of the device, and is favorable for keeping excellent RF performance under the condition of strong vibration environment.
The invention utilizes the grid hole slots formed by the longitudinal positioning finger inserting plate 1 and the transverse positioning finger inserting plate 2 to limit the plane positions of all the bidirectional plugs of the connector in the array, so that the bidirectional plugs can be aligned with the corresponding socket groups at the same time. The crossed finger-shaped clamps are combined and positioned from different directions, so that the connector array is avoided, and the problem that the connectors in the array are difficult to touch by tools is solved; the positioning inserting plate can be positioned in a blind-plugging manner and locked quickly by the method, and reliable installation with small space and high density is realized.
According to the invention, the longitudinal positioning finger-inserting plate 1 and the transverse positioning finger-inserting plate 2 are respectively penetrated into a gap between adjacent jacks of a corresponding socket of a large-scale miniaturized radio frequency blind-insertion connector from the longitudinal direction and the transverse direction, and the positions of the longitudinal positioning finger-inserting plate 1 and the transverse positioning finger-inserting plate 2 are fixed by the right-angled square positioning piece 3, so that the positions of the holes and the slots of the formed grid structure are accurate, and the plane position of the connector in the array can be accurately and reliably limited; all connectors are positioned at once. The relative position of each connector is guaranteed to be correct by utilizing the precision of the clamp, the operation and the use are convenient, special tools are not needed, and the requirement on special skills of operators is avoided.
According to the invention, each hole in the grids of the two groups of positioning finger insertion plates is respectively attached to the outline of each radio frequency blind insertion connector, and by means of the matching of the sizes of the holes of the grids and the external dimensions of the connectors, pins at the opposite positions of the planes of all the radio frequency blind insertion connectors are positioned, so that the high-density pins of the radio frequency blind insertion connector array between microwave assemblies are integrally and simultaneously positioned. The device is convenient to assemble, the assembly quality is improved, the damage probability of the connector is greatly reduced, and the assembly period is greatly shortened.
The method is suitable for positioning the inter-assembly radio frequency blind-mate connector array. For equipment which uses a large number of connectors and is connected in a group blind plugging mode, the method can be used for positioning the plane positions of all the connectors in the whole array at one time, and positioning and plugging of the large number of connectors are completed simultaneously. Especially for the miniaturized and large-scale radio frequency connector array blind plugging, the mounting difficulty can be greatly reduced, the assembling and adjusting time is shortened, the connector damage probability in the assembling process is reduced, and the process cost is reduced while the production efficiency is improved.
