Abstract

An AV terminal includes a plug and a terminal, wherein the plug is composed of an outer sleeve and an inner plug-in terminal arranged at the center of the outer sleeve, the outer sleeve and the inner plug-in terminal are insulated and connected to a signal line respectively; a processing plane is arranged on the terminal column surface, and a through hole is opened on the processing plane so that the signal line passes through the through hole and is welded to the terminal. The utility model avoids the problem that the signal line is easily loosened under stress, and makes the welding between the terminal and the signal line convenient and reliable.

Description

A kind of AV terminal

technical field

The utility model relates to an AV terminal.

Background technique

Generally, TVs, VCRs, DVD players, stereos, speakers, etc., the output or input of video and audio signals are mostly connected by signal connectors to transmit video or audio signals. The signal connector generally used to connect the aforementioned electrical appliances is composed of a socket and a plug. The plug is an AV terminal installed at both ends of the signal line, and the socket is installed on the circuit board of the electrical appliance. The plug of the signal line is plugged into the plug of the electrical appliance to connect two audio-visual appliances, and electronic signals such as images or sounds are transmitted through the signal line.

Currently common AV terminals are shown in Figures 5 and 6, and the tail ends of the binding posts are in the shape of a semicircle. The signal line is directly welded to the end of the terminal by soldering process. This kind of joint is inconvenient to process, and the signal line is easily loosened under stress.

Utility model content

In order to overcome the shortcomings of the prior art, the embodiment of the utility model provides an AV terminal, so that the welding between the terminal post and the signal line is convenient and reliable, and the signal line is not easy to loosen.

The utility model is realized through the following technical solutions: an AV terminal, including a plug and a terminal, the plug is composed of an outer sleeve and an inner plug arranged in the center of the outer sleeve, the outer sleeve and the inner plug Insulate between them and connect the signal wires respectively. A transverse through hole is arranged on the terminal, a processing plane is provided on the cylindrical surface of the terminal, and the through hole is arranged on the processing plane. The shape of the through hole is a racetrack shape, a circle, a rectangle with rounded corners or other reasonable shapes. The signal line passes through the through hole, and realizes welding connection with the terminal post.

Compared with the prior art, the utility model avoids the problem that the signal line connected with the terminal is easily loosened under force, and makes the welding between the terminal and the signal line convenient and reliable.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be pointed out that the specific embodiments described here are only used to explain the utility model, not to limit the utility model.

Embodiment 1 As shown in Figure 1 and Figure 2: an AV terminal, including a plug 1 and a terminal 2, the plug 1 is composed of an outer sleeve and an inner plug arranged in the center of the outer sleeve, the outer sleeve They are insulated from the inner posts and connected with signal wires respectively. The terminal 2 is provided with a transverse through hole. A processing plane is set on the cylindrical surface of the terminal 2, and the through hole is set on the processing plane. The shape of the through hole is racetrack. The signal line passes through the through hole, and achieves solder connection with the terminal 2 .

Embodiment 2 As shown in Fig. 3 and Fig. 4: the terminal 2 of this embodiment is provided with a transverse through hole, and the shape of the through hole is circular. Two parallel processing planes are arranged on the cylindrical surface of the terminal 2, and the through holes are arranged on the processing planes.

The through holes mentioned above include racetrack shape, circle, rounded rectangle and other suitable shapes, which are not listed here.

The above description is a preferred embodiment of the utility model, and any obvious modification to the utility model should be included in the technical concept of the utility model without departing from the concept of the utility model.

Claims (2)
