DETAILED DESCRIPTION

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-7 As shown, this utility model provides a technical solution: a fully enclosed audio female connector interface, including a plastic body 1. The plastic body 1 includes a cylindrical interface portion 101 and a base 102 connected to the interface portion 101. One end of the interface portion 101 is provided with an access hole 103 for inserting a microphone plug 2. The base 102 is provided with a first normally open terminal 104, a second normally open terminal 105, a third normally closed terminal 106, and a fourth normally closed terminal 107. The first normally open terminal 104, the second normally open terminal... Terminal 105 is located on the same side of the base 102. The third normally closed terminal 106 and the fourth normally closed terminal 107 are located on the other side of the base 102. The first normally open terminal 104 and the second normally open terminal 105 include a first closed baffle portion 108, a contact portion 109, and a pin portion 110 connected sequentially from one end to the other. The fourth normally closed terminal 107 includes an outer frame portion 111, an elastic contact portion 112 connected to the inner side of the outer frame portion 111, and a fourth pin portion 113 connected to the outer side of the outer frame portion 111. The third normally closed terminal 106 includes a normally closed contact portion 114 and a third pin portion 115 connected to the normally closed contact portion 114. The upper end of the base 102 is provided with a socket 116 for a first normally open terminal 104 and a second normally open terminal 105. A first sealing baffle portion 108 is located at the socket 116. When the microphone plug 2 in this application is not inserted, the first normally open terminal 104 and the second normally open terminal 105 are in a disconnected state; the third normally closed terminal 106 and the fourth normally closed terminal 107 are connected (closed). In the microphone plug 2 state, when the microphone plug 2 is inserted, the first normally open terminal 104 and the second normally open terminal 105 are connected to the ground terminal of the microphone plug 2, and are in a connected state; the third normally closed terminal 106 and the fourth normally closed terminal 107 are in a disconnected state. This utility model provides a first closed baffle part 108 and a second closed baffle part 122 at one end of the terminal. When the terminal is inserted into the inside of the base 102, the closed baffle of the terminal will block the socket, so that the inside of the product is in a fully enclosed state, which has the effect of dustproof and splashproof.

[0029] Please refer to the following carefully. Figure 5 , Figure 6 and Figure 7The first and second normally open terminals 104 and 105 are provided with anti-disengagement first lifting portions 119 on the pin portions 110; the third normally closed terminal 106 is provided with an anti-disengagement second lifting portion 120 on the third pin portion 115; and the fourth normally closed terminal 107 is provided with an anti-disengagement third lifting portion 121 on the fourth pin portion 113. When the terminals are inserted, the lifting portions are embedded in the seat body, so that the terminals cannot be disengaged in the reverse direction, thereby further providing safety and reliability of the connector.

[0030] The interface portion 101 is provided with an external thread 117, and a matching locking nut 118 is connected to the external thread 117. The seat body 102 is provided with a protrusion 1021 at the side connected to the external thread 117.

[0031] Working principle: When the microphone plug 2 is not inserted, the first and second normally open terminals 104 and 105 are in a disconnected state; the third and fourth normally closed terminals 106 and 107 are in a connected (closed) state. When the microphone plug 2 is inserted, the first and second normally open terminals 104 and 105 are connected to the ground end of the microphone plug 2 and are in a connected state; and the third and fourth normally closed terminals 106 and 107 are in a disconnected state.
