[0025] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0026] Please refer to Figure 1-Figure 3 In order to achieve the above-mentioned purpose, the utility model provides a radio frequency connector, including a main body shell 1, an inner shell 2, a probe assembly 3 and a push rod assembly 4. The main body shell 1 has a accommodating cavity, and the bottom and one end are open. The inner shell 2 is arranged in the accommodating cavity of the shell 1. The probe assembly 3 includes a plurality of small needles 31, left and right needles 32 and a center needle 33 arranged at intervals along the length of the inner shell 2. The bottom pins of the plurality of small needles 31, the left and right needles 32 and the center needle 33 all extend out of the opening at the bottom of the main body shell 1. One end of the center needle 33 away from its pin extends to the opening at the end of the main body shell 1. The push rod assembly 4 is arranged in the inner shell 2 and can be translated relative to the inner shell 2. When the push rod assembly 4 is translated, it drives the left and right needles 32 to connect with different small needles 31, thereby switching the circuit.

[0027] Specifically, Figure 3 As shown, in this embodiment, there are four small needles 31, corresponding to No. 4, 5, 6, and 7, respectively, the left and right needles 32 correspond to No. 2 and No. 3, respectively, and the center needle 33 corresponds to No. 1. In the initial state, the No. 2 and No. 3 positions of the left and right needles 32 are connected to the No. 4 and No. 7 positions of the small needle 31, respectively. When the push rod assembly 4 translates, the No. 2 and No. 3 positions of the left and right needles 32 are disconnected from the No. 4 and No. 7 positions of the small needle 31, and connected to the No. 5 and No. 6 positions of the small needle 31, thereby achieving the purpose of switching the line and better meeting the needs of users.

[0028] Specifically, the main body shell 1 includes a main body upper cover 11 and a main body lower cover 12 that are arranged in a mutually matched manner. The bottom of the main body lower cover 12 is provided with an opening, and a bayonet-type connection portion 13 is provided at the open end of the main body shell 1. The bayonet connection is convenient for plugging and unplugging, and the operation is convenient and fast. The bottom of the main body lower cover 12 is provided with a positioning pin 14, and the positioning pin 14 can be used to position the installation of the connector to avoid deviation when the pins of the probe assembly 3 are plugged into the corresponding sockets during installation, thereby reducing the probability of damage. In this embodiment, the main body upper cover 11 and the main body lower cover 12 are fixed by bolt connection, and disassembly and assembly are simple and fast.

[0029] The inner shell 2 includes a rubber core upper cover 21 and a rubber core lower cover 22 which are matched with each other. The rubber core lower cover 22 is opposite to the bottom opening of the main shell 1. The rubber core lower cover 22 is provided with a plug hole corresponding to the probe assembly 3. The split inner shell structure is more convenient and quick to assemble.

[0030] Preferably, a guide rail 221 for the push rod assembly 4 to translate is provided on the rubber core lower cover 22, providing guidance for the movement of the push rod assembly 4, so that the push rod assembly 4 can complete the work of switching lines better and more smoothly.

[0031] The left and right pins 32 are composed of two pins arranged in parallel on the left and right sides, and the pins include a pin 321 and a contact portion 322 arranged on the pin 321, and the contact portion 322 is in driving connection with the protrusion. Specifically, the contact portion 322 is an elastic conductive sheet, one end of which is connected to the pin 321, and the other end is in driving connection with the protrusion of the push rod 41 on the push rod assembly 4. Specifically, the left and right pins 32, the small pin 31 and the center pin 33 are made of conductive materials such as beryllium copper or gold plating.

[0032] Please refer to Figure 4 The push rod assembly 4 includes a push rod 41 slidably arranged in the inner shell 2, a switching part 42 arranged on the push rod 41, and a pushing part 43 arranged at one end of the push rod 41, and the pushing part 43 penetrates the inner shell 2 and extends out of the outer shell 1. The push rod assembly 4 is made of PC material. Specifically, the push rod 41 is a U-shaped push rod, and the switching part 42 is a protrusion arranged on the inner side of the push rod 41. When the push rod 41 translates, the protrusion pushes the left and right needles 32 to contact other small needles 31 to switch the circuit. In the initial state, the protrusion does not contact the contact part 322. At this time, the 2nd and 3rd positions of the left and right needles 32 are connected with the 4th and 7th positions of the small needle 31 respectively. When the push rod 41 starts to move, the protrusion starts to squeeze the contact part 322 so that it is connected with the 5th and 6th positions of the small needle 31, thereby switching the circuit. In order to better switch the circuit, a protrusion can also be set on the side of the conductive sheet, so that the two protrusions produce compression at the same time, and the circuit switching is faster. The push rod assembly 4 further includes a reset member 44 , which is disposed at one end of the push rod 41 away from the pushing portion 43 , so that the push rod 41 can be reset better after the circuit is switched. The reset member 44 may be a spring.

[0033] Through the above technical scheme, through the mutual cooperation between the push rod assembly 4, the left and right needles 32 and the multiple small needles 31, the left and right needles 32 are in contact with different small needles 31 under the transmission of the push rod assembly 4, thereby realizing the function of switching different lines, better meeting user needs, and being more practical and having a wider range of applications than ordinary connectors. The structures are all arranged in the main body shell 1, and the structure is compact.

[0034] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention. It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0035] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
