Embodiment

Consult Fig. 4 A to Fig. 4 C, for utilizing the section flow chart of the present invention's one first preferred embodiment.

Portable electronic equipment comprises a housing 21, and this housing 21 comprises a socket 23, has the socket 25 corresponding to plug syringe needle section size, in order to insert plug; One plug inserts groove 27, and this socket 23 extends to housing 21 outsides certainly; One protuberance that can freely promote 29 is located at the side that this plug inserts groove 27 openings, can vertically slide with the plug direction of insertion, so that insert the groove of header body.

Plug comprises a body 35, and these body 35 1 ends extend a nail head 37 in order to insert this socket 23, and the other end extends an afterbody 41 that is connected in a plug cord 39.

Be provided with a groove 30 of corresponding protuberance 29 engagings in addition at the body 35 of this plug, can allow this protuberance 29 insert groove and detach backward to stop plug.

Above-mentioned plug inserts groove 27, and this socket 23 extends to housing 21 outsides certainly, uses for plug by to insert this socket 23.Shown in Fig. 4 A to Fig. 4 C, this plug inserts the design of groove 27 according to socket 23, can be located at any position of this portable electronic equipment one side.

Shown in Fig. 4 B to Fig. 4 C, the slide mechanism that this protuberance 29 can utilize prior art for example slide rail or slide way mechanism 28 freely promotes the opening that inserts groove 27 at plug to give prominence to, make that in the following time of state of plug insertion socket 23 being able to vertically slide with its direction of insertion is positioned at the groove 30 of this header body 35 with insertion.

With reference to figure 5A to Fig. 5 B, be the solid operation schematic flow diagram of this first preferred embodiment.

As shown in the figure, after the nail head 37 of plug inserted socket 23, body 35 partly can be positioned at plug and insert groove 27, and promote protuberance 29 and just can be fastened on corresponding groove 30 on the body 35 this moment, so just can reach the effect that prevents that plug from coming off according to axis direction.

In addition, with reference to figure 6, show that this protuberance is free to slide another preferred embodiment of mechanism.As shown in the figure, this protuberance 29 can be connected in an elastic parts 31, and nature following time protrudes in the opening that this plug inserts groove 27, and therefore, during this plug insertion socket 23, but these protuberance 29 proper Elastic buckles are on body 35 in the corresponding groove 30.

Above-mentioned elastic parts 31 for example is a spring.

Though only shown the embolus that utilizes elastic parts 31 and slide mechanism 28 in this article, in the practical application, can utilize anyly is enough to make this protuberance to be free to slide to protrude in the technology of this opening.

With reference to figure 7A to Fig. 7 C, be second preferred embodiment of the present invention.Equally, in the present embodiment, utilize notion same with the above-mentioned embodiment, on the figure of plug, form a groove and reach the effect that prevents that it from coming off from digital portable electronic equipment to utilize the resistance shelves.

In Fig. 7 A to Fig. 7 C, except that the groove shapes of header body 35 and snap in the structure of groove different with previous preferred embodiment, all the other modules all with first preferred embodiment in identical, so all the other identical positions are all prolonged and used previous label in Fig. 7 A to Fig. 7 C, chat bright at this.

Identical with first preferred embodiment, portable electronic equipment comprises a housing 21, and this housing 21 comprises a socket 23, has the socket 25 corresponding to plug syringe needle section size, in order to insert plug; One plug inserts groove 27, and this socket 23 extends to housing 21 outsides certainly.

Described plug equally also comprises a body 35, and these body 35 1 ends extend a nail head 37 in order to insert this socket 23, and the other end extends an afterbody 41 that is connected in a plug cord 39.

The body 35 of this plug is provided with a groove 30 of corresponding protuberance 29 engagings equally, can allow this protuberance 29 insert groove and detach backward to stop plug.

But the body 35 set grooves 51 that it is characterized in that this plug in this preferred embodiment are the L type, and plug inserts corresponding these L type groove 51 places of groove side and can arrange in pairs or groups and establish the protuberance 29 to protrude in opening of being free to slide shown in Fig. 4 A to Fig. 4 C, or as shown in Figure 6 be connected in an elastic parts 31, in nature following time, protrude in the protuberance 29 that this plug inserts groove 27 openings, or at least one projection 50 shown in Fig. 7 A to Fig. 7 C, perpendicular to the plug direction of insertion.

Though only be snapped in the projection 50 that L type groove 51 can utilize the protuberance of elastic parts or slide mechanism 28 or be located at opening part in this article for example, in the practical application, any this opening that protrudes in all can use with the structure that is snapped in when plug inserts in the groove.

With second preferred embodiment shown in Fig. 7 B to Fig. 7 C, when plug inserts groove 27 insertion sockets 23 by plug, slipping into of L type groove 51 than minor face 53 aligning projections 50, again via the rotation of header body, just this projection can be fixed in the longer sides 52 of this L type groove 51, can avoid this plug to come off from this socket 23.

Wherein this L type groove 51 be parallel to the longer sides 57 of this header body 35 than minor face 53, in other words, the longer sides 52 of this L type groove 51 is perpendicular to the longer sides 57 of this header body 35.

With reference to figure 8, show the two L type grooves that comprised on this body, be an alternate embodiment of L type groove.As shown in the figure, this header body 35 can be provided with two L type groove 54 and grooves 56, therefore at opening part two corresponding projections can be arranged also.

With reference to figure 9A to Fig. 9 B, be the solid operation schematic flow diagram of this second preferred embodiment.

As shown in the figure, when the nail head 37 of plug inserts groove 27 insertion sockets 23 by plug, L type groove 54 and groove 56 aimed at projection 50a than minor face, 50b slips into, again via the rotation of header body 35, just this projection can be fixed in the longer sides of this L type groove 54 and groove 56, so can avoid this plug to come off, can reach the effect that prevents that plug from coming off according to axis direction from this socket 23.

Above-mentioned plug is headset plug for example, and socket is earphone socket for example.

Protuberance is embolus for example.

According to the above, the present invention really can fix the effect that the header body realization avoids plug to come off because of external force with a concrete structure.

Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
