Description

Push-in self-locking RF connector

technical field

The utility model relates to the technical field of electrical component plugging, in particular to a push-in self-locking radio frequency connector.

Background technique

RF connectors can be used for interconnection between circuit boards, RF modules and RF modules, and circuit boards and RF modules. Miniaturized, low-cost RF connectors are especially popular in the electronic communications industry. Most of the RF connectors currently on the market use threaded or bayonet connection methods. Auxiliary tools such as wrenches are required for connection, which requires space for operation and is not easy to operate.

Utility model content

The technical problem to be solved by the utility model is to provide a push-in self-locking radio frequency connector. Ensure that the connector is in blind mating state, reliable contact, and at the same time has a certain engagement force and separation force.

In order to solve the above technical problems, the utility model provides a push-in self-locking radio frequency connector, including a plug and a socket. Located in the plug housing, the jack assembly is located in the first pressure sleeve, the jack assembly is isolated from the inner wall of the plug housing by a first insulator, and the inner wall of the first pressure sleeve has a semicircular protrusion; the socket includes a socket housing, The second ferrule, the second insulator and the pin assembly, the socket housing is a metal tube with a tapered surface at one end, the socket housing has a trapezoidal groove corresponding to the semicircular protrusion, and the second ferrule is located on the socket In the housing, the contact pin assembly is located in the second pressing sleeve, and there is a second insulator between the second pressing sleeve and the second pressing sleeve.

For the sake of simple explanation, the push-in self-locking radio frequency connectors described in the present invention are referred to as the radio frequency connectors for short.

The semicircular protrusion on the plug of the radio frequency connector matches the trapezoidal groove on the socket to ensure reliable contact of the radio frequency connector in the state of blind mating, and at the same time has a certain engagement force and separation force. The dimensions of the semicircular bump and the trapezoidal groove have been calculated and verified, so that the plug and the socket can form a 3-point reliable contact between the semicircular bump and the trapezoidal groove when they are in the blind mating state, instead of the conventional blind mating connector. The end face contact or point contact can provide certain engagement force and separation force, so that the RF connector can be reliably contacted.

The distance between the trapezoidal groove and the end face of the socket shell and the distance between the semicircular boss and the end face of the plug shell (mating distance) can be modified according to the ultra-small rectangular or circular mixed connector shell matched with this RF connector , that is, the mating interface of the plug and the socket is a modified SMB structure. If the RF connector is placed in an ultra-small rectangular or circular mixed connector housing, the interface size of the RF connector can also be matched with the entire The insertion depth of the rectangular mixed connector or circular mixed connector shell is the same, which can meet the function of transmitting high-frequency signals in the rectangular or circular mixed connector shell, and can satisfy the mechanical performance in the mated state. , the mating distance takes into account the characteristics of reducing the high-frequency current path and reducing the insertion loss of the RF connector.

The tail of the socket housing has high-frequency external contact lines and microstrip lines, which can be connected with other connectors or microstrip line circuit boards.

The plug housing is a metal tube with an annular groove on the outer wall, so that when the RF connector is placed in an ultra-small rectangular or circular mixed connector housing, the annular groove can allow the RF connector to It is fixed with epoxy glue in the housing of the ultra-small rectangular or circular mixed connector to ensure its position in the mounting plate, and it cannot move when the mixed connector is plugged and unplugged, which meets the fixing of the mixed connector sexual demands.

The self-locking structure at the mating interface of this RF connector is realized by the semicircular protrusion on the plug being stuck in the trapezoidal groove on the socket housing after mating. This self-locking structure must ensure the insertion and withdrawal force. Requirements, but also to ensure the contact resistance requirements, select a semicircular bump with a suitable radius to ensure contact with all three sides of the trapezoidal groove, to obtain ideal electrical and mechanical properties.
