Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

It should be noted that, in the case of no conflict, the technical features in the embodiments and examples of the present invention may be combined with each other, and the detailed description in the specific embodiment should be understood as an explanation of the gist of the present invention, and should not be construed as an improper limitation of the present invention.

The plug socket of the application can be used in electronic equipment, and for convenience of description, in the embodiment of the application, the plug socket is taken as an earphone socket for example. It is understood that the socket may be any kind of socket matched with the plug, and the electronic device may be various types, for example, an electronic device with a socket, such as a mobile phone, a tablet computer, a music player, or a game machine.

Referring to fig. 1 to 5, a socket 100 includes a socket body 1, a contact terminal 2, and an elastic sealing portion 3. The base body 1 is provided with an insertion groove 1a, the insertion groove 1a penetrates through two opposite ends of the base body 1, one end of the insertion groove 1a, which is adjacent to the base body 1, defines an insertion port 1b, the contact terminal 2 is arranged at the other end of the base body 1, which is opposite to the insertion port 1b, and the contact terminal 2 is positioned in the insertion groove 1a and is far away from the insertion port 1 b.

Specifically, when the earphone needs to be used, the plug 200 (refer to fig. 5) of the earphone can be inserted into the plug slot 1a from the plug port 1b, and the contact terminal 2 is mainly used for identifying the earphone, and when the plug 200 of the earphone is contacted with the contact terminal 2, a current signal can be transmitted between the electronic device and the earphone, so that the related function of the earphone can be realized.

The elastic sealing part 3 is located in the insertion groove 1a, the elastic sealing part 3 is connected with the seat body 1 in a sliding manner, and the elastic sealing part 3 can slide between a first position A and a second position B relative to the seat body 1. In the first position a, the elastic sealing part 3 seals the contact terminal 2, and in the second position B, the elastic sealing part 3 exposes the contact terminal 2. Here, the first position a is a position where the contact terminal 2 can be isolated from the outside, and the second position B is a position where the elastic sealing portion 3 can avoid the contact terminal 2 to ensure that the contact terminal 2 can contact with the plug 200.

Only one end of the elastic sealing part 3 in this embodiment is located in the insertion groove 1a, and the other end of the elastic sealing part 3 is fixed to other components in the electronic device after the insertion seat 100 is assembled to the electronic device. It will be appreciated that in another embodiment, the elastic sealing portion 3 may be disposed entirely in the insertion groove 1a, as long as the elastic sealing portion 3 is disposed conveniently.

Referring to fig. 2 and fig. 3, the elastic sealing portion 3 of the present embodiment includes an elastic member 31 and a sealing member 32 connected to the elastic member 31. The elastic element 31 is used for driving the sealing element 32 to slide in the insertion groove 1a relative to the base body 1. The seal 32 seals the contact terminal 2 when the elastic sealing portion 3 is in the first position a; when the elastic sealing part 3 is in the second position B, the sealing member 32 exposes the contact terminal 2.

Specifically, the elastic member 31 and the sealing member 32 may be connected together by means of in-mold injection, dispensing, welding, riveting, or the like. The fixed end of the elastic element 31 of this embodiment protrudes from the end surface of the insertion slot 1a away from the end of the insertion opening 1b, and when the socket 100 is assembled to an electronic device, the fixed end of the elastic element 31 is fixed to other components in the electronic device. The elastic member 31 can slide the sealing member 32 between the first position a and the second position B. The elastic member 31 of this embodiment is a spring, and the type (length, elastic modulus, size, etc.) of the spring can be adjusted according to actual needs, so as to be suitable for various sockets 100. In another embodiment, the elastic member 31 may also be an elastic silicone rubber or a rubber band.

Referring to fig. 4, when an earphone is not inserted into the jack 100, the sealing member 32 is located at an end of the jack 1a away from the jack 1b, the elastic sealing portion 3 is maintained in an initial state without elastic deformation, and at this time, the position of the elastic sealing portion 3 in the jack 100 is the first position a capable of sealing the contact terminal 2. In this position, the sealing member 32 can seal the contact terminal 2, so that the contact terminal 2 is isolated from the outside, thereby blocking water or foreign matters from entering the inside of the insertion groove 1a, and even blocking water or foreign matters from entering other parts in the electronic device through the insertion groove 1a, so as to prevent the contact terminal 2 from being oxidized due to long-term contact with the external environment, and prevent the water or foreign matters from entering the insertion groove 1a and corroding the contact terminal 2 and/or other parts in the electronic device.

Referring to fig. 4, in the process that the sealing element 32 slides relative to the housing 1 from the first position a to the second position B, the elastic element 31 moves in a direction away from the socket 1B. With reference to fig. 4, in the first position a, a predetermined distance L2 is provided between an end surface of the sealing member 32 facing the socket 1b and the socket 1b, and the predetermined distance L2 is 1/3-1/2 of the total length L1 of the inserting groove 1 a.

In the first position a of the elastic sealing part 3, the sealing element 32 of the present embodiment is not sealed at the socket 1b, and the end surface of the sealing element 32 facing the socket 1b has a predetermined distance L2 with respect to the socket 1b, so that the compression of the spring is increased if the effective length of the spring is increased, and accordingly, the plugging force required by the plug 200 during the insertion is also increased, so that the sealing element 32 of the present embodiment is disposed inside the plugging groove 1a when the first position a is reached, and the predetermined distance L2 between the end surface of the sealing element 32 facing the socket 1b and the socket 1b is 1/3-1/2 of the total length L1 of the plugging groove 1a, thereby reducing the effective length of the spring, so that the user can insert the earphone more easily.

In addition, when the earphone is not inserted into the general socket, the socket groove does not have any supporting structure, so when the socket is impacted by external force, the socket groove is easy to deform, and even the socket groove can be damaged seriously, thereby causing that the plug connector can not be inserted into the socket groove or the socket has no function. The sealing member 32 of this embodiment is equivalent to provide a support structure for the insertion groove 1a, so that external stress can be conducted when the insertion seat 100 is impacted by external force, so as to prevent the insertion groove 1a from deforming.

Referring to fig. 5, when the earphone is inserted, the plug 200 contacts the sealing member 32 and pushes the elastic sealing portion 3 to move toward an end away from the socket 1B, the elastic member 31 is elastically deformed and gradually compressed by the push of the plug 200, and when the elastic sealing portion 3 moves to the second position B, the contact terminal 2 contacts the plug 200, so that the related function of the earphone can be realized.

In addition, for a general socket, when a user applies too much force when inserting an earphone, so that the insertion force of the plug is greater than the yield strength of the insertion groove, the insertion groove is also easily deformed, thereby possibly causing the earphone to have the situations of incapability of plugging and unplugging, no function of the insertion seat and the like. The elastic sealing portion 3 of the present embodiment can absorb corresponding impact stress during the insertion process of the plug 200, thereby protecting the plug groove 1 a.

Referring to fig. 4 and fig. 5, the end surface of the sealing element 32 near the insertion port 1b of the present embodiment is formed with the positioning groove 32 a. The shape of the positioning groove 32a is matched with the shape of the end of the plug 200, so that the plug 200 can be well positioned.

With reference to fig. 2 and fig. 4, the sealing element 32 of the present embodiment includes a piston 321 and a sealing ring 322 sleeved on the piston 321, and the sealing element 32 is in sealing contact with an inner wall surface of the seat body 1 at the insertion groove 1a through the sealing ring 322.

Specifically, the sealing ring 322 and the piston 321 may be in interference fit, or may be formed into a whole by dispensing or liquid silicone injection molding. When the elastic sealing portion 3 is located at the first position a, the sealing ring 322 of this embodiment may be in interference fit with an inner wall surface of the seat body 1 located at the insertion groove 1a, so as to perform a sealing function. In general, when the sealing ring 322 is not provided, the sealing function can be achieved only by the piston 321 and the inner wall surface of the seat body 1 at the insertion groove 1a being matched with each other. However, the piston 321 has a certain thickness, and if the piston 321 directly contacts with the inner wall of the insertion groove 1a, the contact area is large, so that the damping applied to the piston 321 during the sliding process is also large, and accordingly, the insertion force required by the insertion plug 200 during the insertion process is also large, and the sealing ring 322 can reduce the contact area between the piston 321 and the inner wall of the seat body 1 at the insertion groove 1a, so that the user can insert the earphone more easily. The sealing ring 322 of this embodiment is a silica gel ring, and silica gel ring temperature resistant range is wide, and chemical properties is excellent. In another embodiment, the sealing ring 322 may be made of other materials, which is not limited herein.

Referring to fig. 2 and fig. 4, the sealing element 32 of the present embodiment is provided with two sealing rings 322, and the two sealing rings 322 are respectively disposed at two ends of the piston 321. The provision of two such sealing rings 322 may further enhance the sealing effect of the sealing member 32. It should be understood that the number of the sealing rings 322 is not limited to two, and the distance between a plurality of the sealing rings 322 may be adjusted according to the actual situation as long as the sealing function is achieved.

Referring to fig. 2, a plurality of grooves 321a are formed on a side wall of the piston 321, and the plurality of grooves 321a are located between the two sealing rings 322 and are spaced apart along a circumferential direction of the piston 321. The groove 321a is provided to provide a sufficient deformation space for the piston 321 during its reciprocating motion.

With reference to fig. 2, fig. 4 and fig. 5, the sealing element 32 of the present embodiment further includes a guiding block 323, the guiding block 323 is disposed on a side wall of the piston 321, and a guiding groove 1c matched with the guiding block 323 is formed on a side wall of the seat body 1 at the insertion groove 1 a.

Specifically, the guide block 323 can slide in the guide groove 1c during the sliding of the sealing member 32, thereby providing a guiding function to the sealing member 32 to prevent the sealing member 32 from being positionally displaced during the sliding. In this embodiment, the piston 321 is provided with two guide blocks 323, the two guide blocks 323 are respectively located at the upper side and the lower side of the piston 321, and correspondingly, the side wall of the seat body 1 located at the insertion groove 1a is formed with two guide grooves 1c, so that the sliding of the sealing element 32 can be better guided.

The above embodiments are only specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
