Abstract

The utility model discloses a coaxial connector with a circuit switching function, which is used for inserting and matching with a butt connector. The coaxial connector includes first, second and third conductors, and a conductive elastic member connected between the first and third conductors. Before the mating connector is inserted and fitted, the third conductor is mated with the second conductor under the pressure of the elastic member so as to communicate with the first conductor and the second conductor. After the mating connector is inserted and mated, the mating connector pushes the third conductor to disconnect from the second conductor, and makes the first conductor conduct with the mating connector through the elastic member and the third conductor.

Description

coaxial connector

【Technical field】

The utility model relates to a coaxial connector, in particular to a coaxial connector with circuit switching function.

【technical background】

In U.S. Patent Publication No. 2002/0160657 published on October 31, 2002, the inventor discloses a coaxial electrical connector that is inserted into a mating connector, which includes an outer conductor with a receiving space, a receiving The axially movable inner conductor in the accommodation space, the conductive ring slidably held on the inner conductor, the terminal accommodated in the accommodation space and perpendicular to the axial direction, and the elastic recovery element fixed in the accommodation space. The elastic recovery element includes a base and an elastic portion extending from the base and abutting against the conductive ring. When the butt connector is not inserted into the storage space, the inner conductor is electrically connected to the terminal through the conductive ring; when the butt connector is inserted into the storage space, the butt connector axially pushes the conductive ring to elastically deform the elastic part of the elastic recovery element, The butt connector is electrically connected to the inner conductor and the terminal is disconnected from the inner conductor.

However, the above-mentioned elastic recovery element is an artificial rubber (or similar polymer) element, and its product structure is relatively complicated and the cost is high.

【Content of utility model】

The problem to be solved by the utility model is to provide a coaxial connector with simple structure and low cost.

In order to solve the above technical problems, the coaxial connector of the utility model is used for inserting and mating with the butt connector, and has a circuit switching function. The coaxial connector includes first, second and third conductors, and a conductive elastic member connected between the first and third conductors, and before the mating connector is inserted and fitted, the third conductor is under the pressure of the elastic member Cooperate with the second conductor so that the first and second conductors communicate. After the butt connector is inserted and fitted, the butt connector pushes the third conductor to disconnect it from the second conductor, and makes the first conductor pass through the elastic member and the second conductor. The three conductors are in conduction with the butt connector.

Compared with the prior art, the coaxial connector of the utility model has the following advantages: the coaxial connector has a simple structure, and its elastic member is directly installed between the first and third conductors to complete the first and second conductors. Conductive connection between the first conductor and the mating connector.

Referring to the accompanying drawings, the utility model will be further described in conjunction with specific embodiments.

【Detailed ways】

Please refer to FIGS. 1-3 , the coaxial connector 100 of the present invention is used for inserting and mating with the butt connector 200 , and has a circuit switching function.

The coaxial connector 100 includes an outer conductor 1, first, second and third insulators 2, 3, 4 fixed in the outer conductor 1, first and second insulators fixed in the first and second insulators 2, 3 Conductors 5 , 6 and a third conductor 7 which is a sliding fit within the third insulator 4 . The outer conductor is provided with a receiving space 101 extending along an axis. The first and third conductors 5 and 7 are disposed in the accommodation space 101 along the axial direction, and the second conductor 6 is also accommodated in the accommodation space 101 and extends out of the outer conductor 1 perpendicular to the axial direction.

The coaxial connector 100 also includes an elastic member 8 . Both ends of the elastic member 8 are held respectively in the first and third central insertion holes 501 and 701 provided by the first and third conductors 5 and 7 , so that the first and third conductors 5 and 7 are electrically connected. The third conductor 7 includes a protruding portion 702 capable of contacting with the second conductor 6 .

Please refer to FIG. 2 , before the mating connector 200 is inserted and fitted, the third conductor 7 is mated with the second conductor 6 under the pressure of the elastic member 8 so as to communicate with the first and second conductors 5 and 6 . As shown in Figure 3, after the mating connector 200 is inserted and mated, the mating connector 200 pushes against the third conductor 7 to disconnect it from the second conductor 6, and makes the first conductor 5 pass through the elastic member 8 and the third conductor 7 It is electrically connected with the docking connector 200 .

In this embodiment, the elastic member 8 is a simple spring member, which is directly electrically connected between the first and third conductors 5, 7, without adding an additional elastic recovery element, it can be connected to the butt connector. After the 200 is pulled out, the third conductor 7 is pushed, so that the third conductor 7 is in electrical contact with the second conductor 6 .
