Headphone jack assembly

The present invention relates to a headphone jack assembly, and more particularly to a headphone jack assembly for use in a portable electronic device such as a mobile phone.

At present, electronic devices such as mobile phones, semiconductors, electronic dictionaries, and the like are often provided with a headphone jack, and a plug of a headphone is inserted into the headphone jack, so that the user can directly listen to the audio signal played by the electronic device through the earphone.

Now, the earphone socket is applied to a mobile phone as an example. Referring to FIG. 1, the mobile phone includes a mobile phone case 10 and a headphone jack 20. A frame 12 having a substantially "ㄇ" shape is protruded from the inner surface of the mobile phone casing 10. The frame 12 and the side wall of the mobile phone casing 10 are enclosed by a receiving groove 14 and accommodated. A through hole 16 is defined in the side wall adjacent to the groove 14. The earphone socket 20 includes a socket body 22, and an integrally formed socket 24 is protruded from one side of the socket body 22. The socket 24 has a socket 26. When the earphone socket 20 is installed, the socket 24 is first inserted into the through hole 16, and then the socket body 22 is received in the receiving slot 14 to fix the earphone socket 20 in the casing 10 of the mobile phone.

Therefore, since the earphone socket 20 is directly disposed on the casing 10, in order to enable the earphone socket 20 to be firmly fixed in the casing 10 of the mobile phone, the precision of the matching between the receiving slot 14 and the earphone socket 20 is required. High, the size of the receiving groove 14 To be consistent with the headphone jack 20, this requires a higher processing technique for manufacturing the housing 10. If the dimensional accuracy of the accommodating groove 14 is not high, the earphone socket 20 is easily fixed. Further, when the case 10 to which the headphone jack 20 is mounted is subjected to a plating process, the appearance defect rate is often caused by the fact that the circumference of the cylindrical hole holder 24 cannot be completely plated.

In view of the above, it is necessary to provide a headphone jack assembly that is relatively rigid and can improve the appearance yield.

An earphone socket assembly is disposed in a casing of an electronic device, the casing having a side wall, the earphone socket assembly comprising a socket body, a fixing base made of a soft material, and a hole seat The socket body is separated from each other, and the socket is abutted on the side wall. The socket body is received in the fixing base and fixed to the housing together with the socket body, and the socket body is abutted on the socket.

Compared with the prior art, the earphone socket assembly adopts a split structure, and the hole base and the socket body are separated from each other, and the hole seat can be separately plated before the earphone socket assembly is installed, thereby improving the surface plating of the hole seat. rate. In addition, the fixing structure is simple, and the precision of the cooperation with the socket body and the receiving groove can be easily controlled when the fixing seat is manufactured, so that the socket body can be relatively firmly fixed in the casing of the electronic device.

3 is an exploded perspective view of the socket body and the fixing base in the earphone socket assembly according to the preferred embodiment of the present invention.

Figure 4 is an assembled view of Figure 3 of the present invention.

The present invention discloses a headphone jack assembly, which is illustrated by way of example in the preferred embodiment of the present invention.

Referring to FIG. 2, the mobile phone has a casing 30. The casing 30 includes a bottom wall 31 and side walls 32 extending from the edge of the bottom wall 31. A frame body 34 having a substantially "ㄇ" shape is formed on the bottom wall 31 of the side wall 32. The frame body 34 and the side wall 32 collectively define a receiving groove 35. A through hole 33 is defined in the side wall 32 surrounded by the frame body 34.

Referring to FIG. 3 , the earphone socket assembly 40 includes a socket body 41 , a fixing base 42 and a hole holder 43 . The socket body 41 is substantially in the shape of a rectangular block and includes two opposite side portions 410 and two opposite end portions 412. A latching portion 4102 is respectively protruded from the two side portions 410. A circular jack 4122 is defined in the one end portion 412, and the jack 4122 is used for receiving a plug (not shown) of the earphone.

The fixing base 42 includes a base plate 420 , a left side plate 421 , a right side plate 422 and a top plate 423 . The substrate 420 is rectangular and has a length slightly smaller than the length of the socket body 41. The left side plate 421 and the right side plate 422 are respectively disposed on opposite sides of the substrate 420. A gap 424 is defined in the middle of the left side plate 421 and the right side plate 422 and the substrate 420. The latching portion 4102 of the socket body 41 is engaged to fix the socket body 41 to the fixing base 42. on. The top plate 423 is disposed at one end of the substrate 420 and is disposed together with the left side plate 421 and the right side plate 422 to form a receiving cavity 425 for receiving the socket body 41. The holder 42 of the preferred embodiment of the present invention is integrally formed and made of a soft material. The preferred material of the present invention is rubber, which allows the holder 42 to closely fit the socket body 41.

The socket 43 includes a body 430 and a flange 432. The sheet body 430 is formed by bending a substantially rectangular sheet having a flange 4304 at one end. A circular hole 4306 is defined in the sheet body 430. The flange 432 protrudes from the periphery of the circular hole 4306. The socket 43 of the preferred embodiment of the present invention is also integrally formed.

When assembling, please refer to FIG. 4 together, the socket body 41 is firstly engaged with the notch 424 by the latching portion 4102, and the socket body 41 is fixed in the receiving cavity 425. Since the length of the socket body 41 is greater than the length of the fixing base 42, the socket body 41 protrudes from the substrate 420 to form a convex portion 44. Then, the flange 432 is inserted into the through hole 33 to abut the hole 43 on the inner side of the side wall 32. Finally, the fixing seat 42 to which the socket body 41 is fixed is placed in the accommodating groove 35, and the convex portion 44 is abutted on the hem 4304 of the hole holder 43, and the end portion 412 of the circular hole 4122 is abutted thereon. The socket 43 is aligned with the through hole 33 and the earphone socket assembly 40 is fixed in the housing 30 of the mobile phone.

The earphone socket assembly 40 adopts a split structure, and the hole holder 43 and the socket body 41 are separated from each other, and the hole holder 43 can be separately plated before the earphone socket assembly 40 is mounted, thereby improving the surface plating yield of the hole holder 43. . In addition, the fixing base 42 has a simple structure, and when the fixing base 42 is manufactured, it is easy to control the matching precision with the socket body 41 and the receiving groove 35, so that the socket body 41 can be firmly fixed to the mobile power.
