Description

An audio connector with a fixing piece

technical field

The utility model relates to the technical field of connector products, in particular to an audio connector with a fixing part.

Background technique

Connectors are the main adapters for electrical signal transmission in various electronic products. Among them, audio connectors specially provided for audio signal output/input are widely used in various audio-visual products, especially near In recent years, with the rapid development of various portable electronic products, such as mobile phones, IPADs, recording pens, notebook computers, etc., audio interfaces of various sizes are widely used.

In actual production and use, when the audio plug is inserted into the audio connector, the tail of the audio connector is prone to unbalanced force, and the audio plug will abut against the tail of the insulating shell after being inserted, resulting in The tail of the insulating housing needs to bear a relatively large force; if the tail of the insulating housing is subject to a large upward force, it is easy to make the terminal detach from the solder joint, resulting in disconnection of the circuit.

Utility model content

Aiming at the problems in the prior art, the utility model provides an audio connector with a fixing part.

The utility model adopts the following technical solutions:

An audio connector with a fixing part, including an insulating housing and a number of metal terminals, the insulating housing is provided with a jack for plug insertion and a number of terminal slots for metal terminals to pass through, and also includes a A fixture that holds the insulating case in place.

Wherein, the fixing member includes a fixing plate and pins, and the fixing plate and the pins are integrally formed; the pins are provided with buckle holes and welding feet, and the insulating housing is provided with a buckle hole to cooperate with the buckle hole. The bumps are interlocked with the snap holes, and the fixing member is fixed on the insulating housing.

Wherein, the metal terminal includes a ground terminal, a microphone terminal, a left channel terminal and a right channel terminal, the ground terminal and the microphone terminal are symmetrically placed on the front end of the insulating housing, and the left channel terminal is placed on the The middle part of the insulating shell, the right channel terminal is passed through the end of the insulating shell.

Wherein, a PCB board is arranged under the insulating housing.

Wherein, the metal terminal is provided with a welding foot, and the welding foot is welded on the PCB board.

Beneficial effects of the utility model: the rear part of the insulating shell of the connector is buckled and fixed by adding the fixing part, which ensures the stable connection of the connector on the base and avoids the large upward force caused by the tail of the insulating shell. The warped force sometimes makes the terminal detached from the solder joint, causing the circuit to be disconnected. This structure also has the advantages of reasonable design, simple installation, and easy maintenance.

detailed description

In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the implementation modes are not limitations of the utility model. Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1 and Figure 2: an audio connector with a fixing piece, including an insulating shell 2 and a number of metal terminals, the insulating shell 2 is provided with a jack for plug insertion and a number of metal terminals The pierced terminal slot also includes a fixing piece 7 capable of fixing the insulating housing 2 . In this embodiment, the fixing member 7 includes a fixing plate and pins, and the fixing plate and the pins are integrally formed; There are bumps matched with the fastening holes, and the fixing member 7 is fixed on the insulating housing 2 through the mutual fastening of the bumps and the fastening holes. In this embodiment, a PCB board 1 is provided under the insulating case 2 , and solder legs are provided on the metal terminals, and the solder legs are welded on the PCB board 1 . The utility model adds a fixing part 7 to the rear part of the insulating shell 1. When the audio connector is installed on the PCB board, the metal terminals and the welding legs of the fixing part 7 are welded and fixed to the PCB board respectively, so that the entire audio connection The device is fixed on the PCB board, which ensures the stable connection of the audio connector, and avoids the problem that the terminal is separated from the solder joint when the tail of the insulating shell 1 bears a large upward force, which leads to the disconnection of the circuit. The new design is reasonable, easy to install, easy to maintain and so on.

In this embodiment, the metal terminals include a ground terminal 3, a microphone terminal 4, a left channel terminal 5, and a right channel terminal 6, and the ground terminal 3 and the microphone terminal 4 are symmetrically placed in the insulating housing 2. At the front end, the left sound channel terminal 5 is passed through the middle of the insulating shell 2 , and the right sound channel terminal 6 is passed through the end of the insulating shell 2 . The metal terminal adopts different insertion directions according to different insertion positions, which allows the operator to easily identify the functional properties of the metal terminal, which is convenient for installation and maintenance. The right channel terminal can also realize the function of judging whether the plug is fully inserted into the connector.

The above is only the preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as above with the preferred embodiment, it is not used to limit the utility model. Anyone who is familiar with the utility model Professional technicians, without departing from the scope of the technical solution of the present utility model, should use the technical content disclosed above to make some changes or modify equivalent embodiments with equivalent changes, but if they do not deviate from the technical solution of the present utility model, according to this The utility model technology refers to any simple modification, equivalent change and modification made to the above embodiments, which all belong to the scope of the utility model technical solution.
