Wherein, the insulating seat 10 is composed of a front seat body 11 and a rear seat body 12 . The front base body 11 is stacked with three accommodation cavities for the audio plug 70 to be inserted sequentially from top to bottom, namely the first accommodation cavity 111, the second accommodation cavity 112 and the third accommodation cavity 113; one end surface of the front base body 11 There are three positioning holes corresponding to the aforementioned accommodating cavities, namely the first positioning hole 114, the second positioning hole and the third positioning hole 116. Each positioning hole communicates with its corresponding accommodating cavity. The rear base body 12 is fixedly mounted on the rear end of the front base body 11 , and the bottom surface of the rear base body 12 is used as an assembly end surface 121 between the connector and the circuit board.

The elastic contacts 411 of the two signal terminals 41 protrude into the first accommodating cavity 31 so as to abut and conduct with the mated audio plug 70 . Among the two switch terminals 42, an insulating sleeve 44 is set on the elastic arm of one of the switch terminals 42; The arm abuts against the conductive pushing portion 412 of the other switch terminal, thereby making the two switch terminals 42 in a normally open state when the audio plug 70 is not inserted.

In particular, since the audio output terminal group 40 and the first vacant cavity 31 are far away from the aforementioned assembly end surface 121, in order to effectively solve the problem of difficult processing caused by the extension of the terminal pins, the present embodiment combines the signal terminal 41 and the switch The terminal 42 is set to be composed of a separate terminal body 401 and a terminal pin 402. The terminal body 401 is arranged in the front seat body 11. The terminal pin 402 is composed of a first curved arm 402a and a second curved arm 402b perpendicular to each other.

Among the two switch terminals 52, an insulating sleeve 54 is set on the elastic arm of one of the switch terminals. The other switch terminal abuts against the conducting push portion 512 , thereby making the two switch terminals in a normally open state when the audio plug 70 is not inserted.

Similarly, since the audio input terminal group 50 and the second accommodating cavity 32 are far away from the assembly end surface 121, in order to effectively solve the problem of difficult processing caused by the extension of the terminal pins, this embodiment uses the signal in the audio input terminal group The terminal 51 and the switch terminal 52 are also configured to be assembled by a separate terminal body 501 and a terminal pin 502. The terminal body 501 is arranged in the front seat body 11. The terminal pin 502 is composed of a first curved arm 502a and a The second bent arm 502b forms an L-shaped structure.

Different from the aforementioned audio output terminal group 40 and audio input terminal group 50, since the audio amplifier terminal group 60 and the third accommodating cavity 33 are closer to the assembly end surface 121, the terminal pin 602 is provided by the terminal body 601. When it is extended integrally, it will not be too long. Therefore, the terminal pins 602 of the signal terminal 61 and the switch terminal 62 in the audio amplifier terminal group 60 are directly integrally extended from the terminal body 601, and extend out of the rear seat body. The assembly is connected to the outside of the end face 121.

In addition, the ground terminals of the aforementioned audio output terminal group 40, audio input terminal group 50, and audio amplifier terminal group 60 are a common conjoined structure, which includes a main body rod 80, and three vertically extending integrally from the main body rod. Three elastic arms 43, 53, 63, the three elastic arms 43, 53, 63 are respectively inserted into the first accommodating chamber 111, the second accommodating chamber 112 and the third accommodating chamber 113, as audio output terminals As for the ground terminals of the group 40 , the audio input terminal group 50 and the audio amplifier terminal group 60 , the pin 81 end of the main body rod 80 is inserted out of the assembly end surface 121 .

As Fig. 9 and Fig. 10, have shown the internal structural relation of audio frequency output connector unit in the present embodiment, when audio plug 70 is inserted, this audio plug 70 impels the signal terminal 41 that conflicts with it to deform elastically, and this signal terminal 41 deforms During the process, the pushing part 412 on it just acts on the insulating sleeve 44, pushing the elastic arm of the switch terminal 42 to deform downward until it contacts with the other switch terminal 42 for conduction. Since the internal structural relationship between the audio input connector unit and the audio amplifier connector unit is basically the same as that of the aforementioned audio output connector unit, details will not be repeated here in this embodiment.

The key point of this utility model is that, on the one hand, by setting an insulating seat that can accommodate a plurality of connector terminal groups at the same time, and setting a plurality of butt joints corresponding to the connector terminal groups, the butt joints can be set Different colors are used to facilitate users to distinguish the plugging of connector units with different functions.
