Description

Audio connector and its audio plug

The present invention relates to a connector, and more particularly to an audio connector and an audio plug therefor.

An audio connector generally used in an electronic device includes an audio plug and a socket mounted in the electronic device, and the audio plug includes a connection terminal and an outer casing that is insulated from the connection terminal. The connecting terminal portion extends out of the casing to be inserted into the casing and conducts an audio signal. Due to the manufacturing process, the connecting terminal is formed with a metal flange relative to the root of the outer casing. When the audio plug is inserted into the socket, the metal flange abuts against the outer edge of the socket and is exposed to the air when the user inserts the audio plug. When it is placed on the socket, static electricity generated between the user and the audio connector easily enters the inside of the electronic device from the metal flange, possibly damaging the internal circuit of the electronic device.

In view of the above, it is necessary to provide an anti-static audio connector and an audio connector thereof.

An audio connector for an electronic device that includes an audio plug and a receptacle that mates with the audio plug. The audio plug includes a connection terminal and an insulated outer casing. The housing includes a body covering the connection terminal, and the connection terminal includes a metal flange adjacent to the body and located outside the body, and a contact portion for electrically connecting the audio plug to the socket. The socket includes a socket that receives the connection terminal. The housing further includes an insulation disposed on the body a shielding portion surrounding the shielding metal flange and protruding the metal flange in a direction in which the connecting terminal extends, so that when the connecting terminal is inserted into the plug portion, the protruding portion of the shielding portion resists the insertion The end surface of the joint portion, together with the plug portion, completely shields the metal edge and the contact portion to prevent static electricity from acting on the metal flange or the contact portion.

An audio plug for connecting to a socket in an electronic device. The audio plug includes a connection terminal and an insulated outer casing. The outer casing includes a body that covers the connection terminals. The connecting terminal includes a metal flange adjacent to the body and located outside the body, and a contact portion for electrically connecting the audio plug. The housing further includes a shielding portion that surrounds the metal flange and protrudes the metal flange in an extending direction of the connecting terminal, so that the shielding portion protrudes when the connecting terminal is inserted into the socket Partially abutting the end face of the socket and completely shielding the metal flange and the contact portion together with the socket to prevent static electricity from acting on the metal flange or the contact portion.

When the audio plug is plugged into the socket, the shielding portion will surround the shielding metal flange so as not to be exposed to the air, thereby preventing static electricity from entering the electronic device through the metal flange and damaging the electronic device, thereby preventing the static electricity.

The audio connector of the present invention and its audio plug will be further described in detail below with reference to the accompanying drawings and embodiments.

Referring to FIG. 1, an audio connector 200 according to an embodiment of the present invention includes an audio plug 21 and a socket 23 that matches the audio plug 21.

Referring to FIGS. 2 and 3, the audio plug 21 includes an insulating housing 211, a connecting terminal 213, and two cables 215. The outer casing 211 includes a cylindrical body 2111, a truncated-shaped wiring portion 2113 formed at one end of the main body 2111, and a circular shielding portion 2114 formed at the other end of the main body 2111. In the direction away from the body 2111, the diameter of the wiring portion 2113 becomes smaller and smaller. One end of the connection terminal 213 is fixed in the outer casing 211, and the remaining portion protrudes outside the outer casing 211. The portion of the connection terminal 213 that protrudes outside the outer casing 211 includes a metal flange 2130, a first contact portion 2131, a second contact portion 2133, a positioning portion 2135, a first isolation portion 2137, and a second isolation portion 2139. The metal flange 2130, the first contact portion 2131, the second contact portion 2133, and the positioning portion 2135 are sequentially arranged in a direction away from the body 2111. The first isolation portion 2137 and the second isolation portion 2139 are made of an insulating material, wherein the first isolation portion 2137 is located between the first contact portion 2131 and the second contact portion 2133 and isolates the first contact portion 2131 and the second contact portion 2133. . The second isolation portion 2139 is located between the second contact portion 2133 and the positioning portion 2135 and isolates the second contact portion 2133 and the positioning portion 2135. The positioning portion 2135 has a truncated cone shape for positioning the audio plug 21 when inserted into the socket 23. The diameter of the positioning portion 2135 gradually increases in a direction away from the body 2111 of the outer casing 211. The second cable 215 enters the outer casing 211 from the end of the connecting portion 2113 away from the body 2111. One cable 215 is connected to the first contact portion 2131, and the other cable 215 is connected to the second contact portion 2133.

The socket 23 includes a seat body 231 having a substantially rectangular parallelepiped shape, five legs 233, and a plug portion 235. The four terminals 233 are formed at one end of the base 231, and the insertion portion 235 is formed at the other end of the base 231. A plug hole 2351 through which the connection terminal 213 is inserted is formed in the plug portion 235. The socket 23 also has a corresponding portion of the positioning portion 2135 of the connection terminal 213. The engaging structure (not shown) is used to position the connecting terminal 213.

In use, the socket 23 is mounted in an electronic device (not shown), and the terminal 233 is connected to the internal circuit board of the electronic device. The connection terminal 213 of the audio plug 21 is inserted into the insertion hole 2351 of the socket 23, and the positioning portion 2135 of the connection terminal 213 is engaged with the engagement structure in the socket 23 to position the connection terminal 213. The first contact portion 2131 and the second contact portion 2133 are respectively in contact with corresponding components in the socket 23 to electrically connect the audio plug 21 and the socket 23. The shielding portion 2114 abuts the insertion portion 235 of the socket 23, so that the shielding portion 2114 and the insertion portion 235 surround and shield the metal flange 2130, the first contact portion 2131 and the second contact portion 2133 of the connection terminal 213. When the audio plug 21 is inserted, even if static electricity is generated, since the shielding portion 2114 and the insertion portion 235 are blocked, the circuit board is not damaged by the socket 23 and is damaged to the inside of the electronic device, thereby protecting the electronic device.

The shielding portion 2114 can be integrally formed on the body 2111, or can be integrally formed and fixedly disposed at a position adjacent to the metal flange 2130 of the body 2111, and shields the metal flange 2130.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the spirit of the invention are intended to be included within the scope of the following claims.
