Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Prior to further elaborating on the embodiments of the present application, some of the existing structures referred to in the examples of the present application will be explained.

A USB socket: a part of the socket, which has a tongue part (not shown), wherein the tongue part has a plurality of pins to match with the USB plug; the tongue portion is usually made of a hard plastic.

A USB plug: referring to fig. 1, including a housing 33 and a solid portion 31; the housing 33 is a rectangular housing and has a hollow interior; the solid portion 31 is also rectangular parallelepiped and located on one side of the inside of the housing 33; the region of the inside of the housing 33 other than the solid portion 31 constitutes a hollow portion 32; a plurality of pins (not shown in the figures) are provided on the solid portion 31 so as to be matched with the tongue portion in the USB socket; the material for the housing 33 is usually stainless steel, and the material for the solid portion 31 is usually hard plastic.

In order to make the technical solutions and advantages of the present application clearer, the following will describe the embodiments of the present application in further detail with reference to the accompanying drawings.

With the development of science and technology, various types and different purposes of electronic equipment appear in daily life of people, such as mobile phones, tablet equipment, notebook computers and the like. Taking a mobile phone as an example, the mobile phone has the functions of being convenient to carry and being capable of achieving a plurality of functions (such as making a call, sending a short message, checking a route, booking a hotel, taking a car, and the like), so that the mobile phone becomes an indispensable part of daily life of people.

In order to facilitate people to charge electronic equipment, be equipped with USB socket on more and more sockets for people need not to carry the charging plug, when needs charge for electronic equipment, only need with the USB plug of charging wire one end from having with the USB open-ended socket panel corresponding with USB socket insert in the USB socket can.

Currently, although the USB socket is convenient to use, if the USB plug is inserted too much due to an applied insertion force or too fast insertion speed, the USB plug is prone to collision of the tongue piece portion inside the USB socket. Because tongue piece portion in the USB socket is rigid plastic, the ability of resisting collision is relatively weak, especially by the back of many times of collisions, very easily produces the damage, leads to the unable normal use of USB socket in succession. Therefore, it is highly desirable to provide a device capable of protecting a USB socket in the case where a USB plug is applied with a large insertion force or inserted at a fast insertion speed.

In view of this, the present embodiment provides a device 1 for protecting a USB socket, the device 1 is adapted to be disposed between a socket panel 2 and the USB socket, the socket panel 2 has a USB opening 21 corresponding to the USB socket. The structure of the device 1 can be seen in fig. 2-3.

Referring to fig. 2, the apparatus 1 includes a carrier 11 and a protective door assembly 12.

Wherein, one end of the protection door assembly 12 is elastically connected with the bearing seat 11, and the bearing of the protection door assembly 12 can be realized by utilizing the bearing seat 11.

The protective door component 12 can elastically move on the bearing seat 11 along the length direction of the USB socket, so that the protective door component 12 can shield at least part of the USB socket when in a natural state and can expose the USB socket when in a compressed state. Here, the protective door assembly 12 may shield all USB sockets or a part of the USB sockets when in a natural state, so that the USB plug cannot directly enter the USB sockets when being inserted; when the shutter assembly 12 is in the compressed state, the USB plug may enter the USB socket as the USB socket is exposed.

Since the device 1 for protecting a USB socket of the present application can protect a plurality of USB sockets at the same time, the device 1 may include a plurality of protection door assemblies 12.

The working principle of the device 1 for protecting the USB socket provided by the embodiment of the present application is as follows:

when the USB plug is inserted from the USB opening 21 of the socket panel 2, the protection door component 12 shields at least part of the USB socket, so that the USB plug is firstly contacted with the protection door component 12 before entering the USB socket, the protection door component 12 plays a role in buffering, and the insertion speed of the USB plug is effectively reduced or the insertion force exerted on the USB plug is reduced; then in the continuous inserting process of the USB plug, the USB plug can press and push the protective door component 12 to elastically move along the length direction of the USB socket until the protective door component 12 moves to the position where the USB socket is exposed, and the USB plug can enter the USB socket to be matched with the USB socket for use.

Referring to fig. 2, in order not to obstruct the USB plug from entering the USB socket, the bearing seat 11 is provided with a communication hole 111 corresponding to the USB socket, so that the USB plug can enter the USB socket through the communication hole 111. In other words, there is a one-to-one correspondence positional relationship between the USB socket, the communication hole 111, and the USB opening 21.

Therefore, the device for protecting the USB socket provided by the embodiment of the application can utilize the protection door assembly 12 arranged to realize the insertion buffering of the USB plug in the process that the USB plug is inserted into the USB socket, and avoid the collision between the USB plug applied with larger insertion force or having higher insertion speed and the tongue piece part in the USB socket to damage the tongue piece part, thereby effectively prolonging the service life of the USB socket.

In one possible design, referring to fig. 2, the protective door assembly 12 includes a protective door body 121 and a first elastic buffer element 122, one end of the first elastic buffer element 122 is connected to the protective door body 121, and the other end is connected to the bearing seat 11.

According to the arrangement, when the USB plug is inserted, the USB plug is in contact with the protective door body 121 to push the protective door body 121 to move along the length direction of the USB socket until the protective door body moves to the position where the USB socket is exposed, the moving distance of the protective door body 121 reaches the maximum, and in the whole process that the USB plug enters the USB socket and is matched with the USB socket, the position of the protective door body 121 is kept unchanged under the limiting effect of the USB plug; in the moving process of the protection door body 121, the first elastic buffer device 122 is disposed between the protection door body 121 and the carrying seat 11, so that the moving process is an elastic movement.

When the USB plug is pulled out from the USB socket, because the protection door body 121 is no longer limited by the USB plug, under the effect of the elastic force of the first elastic buffer device 122, the protection door body 121 is restored to the position in the natural state, i.e. at least part of the USB socket is shielded.

Alternatively, the first elastic buffer device 122 may be a spring or an elastic plastic pad. Wherein, the preferred spring, the preparation of convenient material and the elasticity coefficient of settlement.

Taking the first elastic buffer device 122 as an example of a spring, the elastic coefficient of the spring can determine the degree of the buffering effect of the protective door assembly 12. When the elastic coefficient of the selected spring is small, the protective door assembly 12 can play a small role in buffering; when the spring constant of the selected spring is large, the protective door assembly 12 can play a large role in buffering. In practical applications, the elastic coefficient of the spring may be selectively set according to a use position, a use frequency, a use object, and the like.

Further, referring to fig. 2, the bearing seat 11 and the protective door body 121 are respectively provided with a first connecting column 112 and a first fixing groove (not shown), and two ends of the spring are respectively sleeved on the first connecting column 112 and fixed in the first fixing groove, so that one end of the spring is connected with the bearing seat 11, and the other end is connected with the protective door body 121. In addition, other implementations for the fixation of the spring are possible. For example, in some embodiments, the bearing seat 11 and the protection door body 121 have a first connection post 112 and a second connection post (not shown), respectively, and two ends of the spring are respectively sleeved on the first connection post 112 and the second connection post. For another example, in some embodiments, the bearing seat 11 and the protection door body 121 respectively have a second fixing groove (not shown) and a first fixing groove, and two ends of the spring are respectively fixed in the second fixing groove and the first fixing groove.

Alternatively, both ends of the first elastic buffer device 122 may be bonded to the carrier 11 and the protection door body 121 by an adhesive, respectively.

Optionally, the number of the first elastic buffer devices 122 is at least one, and may also be multiple, and is not limited herein. For example, referring to fig. 2, the number of the first elastic buffer devices 122 may be two.

In one possible design, referring to fig. 2, the side of the protection door body 121 facing the socket panel 2 has a first inclined surface 1211, and the distance between the first inclined surface 1211 and the socket panel 2 gradually increases from the side of the first inclined surface 1211 close to the first elastic buffer element 122 to the side far away from the first elastic buffer element 122.

With this arrangement, when the USB plug is inserted, the USB plug contacts the first inclined surface 1211 of the shutter body 121, so that the first inclined surface 1211 receives a pushing force in the insertion direction of the USB plug, and when the pushing force acts on the first inclined surface 1211, the pushing force can be decomposed into a force in the insertion direction of the USB plug and a force in the direction along the length of the USB socket and toward the first elastic buffer member 122. Under the force in the direction along the length of the USB socket and toward the first elastic buffer piece 122, the protective door body 121 moves along the length of the USB socket and toward the direction of the first elastic buffer piece 122.

Alternatively, referring to fig. 2, both opposite side surfaces of the protective door body 121 parallel to the length direction of the USB socket may extend in a direction opposite to the insertion direction of the USB socket to form reinforcing walls 1217 on both sides of the first inclined surface 1211 for enhancing the strength of the protective door body 121.

In a possible design, referring to fig. 2, the bearing seat 11 has a guide rail 13 disposed along the length direction of the USB socket, and the side of the protection door body 121 away from the socket panel 2 contacts the guide rail 13 and can move elastically along the guide rail 13.

Through setting up guide rail 13, provide the direction for the removal of shutter body 121, can effectively prevent shutter body 121 and take place the skew in the removal process to ensure the smooth insertion of USB plug.

Accordingly, referring to fig. 4, in order to fit the guide rail 13, the side of the protective door body 121 away from the socket panel 2 has a stopper 1215, so that the guide rail 13 is restricted to slide within the stopper 1215.

Alternatively, referring to fig. 2, the number of the guide rails 13 may be two and symmetrically located at both sides of the communication hole 111.

In one possible design, the guide rail 13 has a stopper 14 thereon, and the stopper 14 is configured to abut against the protection door body 121 when the protection door body 121 is in a natural state, so as to limit the protection door body 121.

Alternatively, referring to fig. 2, the number of the stoppers 14 may be two, and the stoppers are symmetrically located at both sides of the communication hole 111.

Optionally, with reference to fig. 2, a receiving groove 1216 may be formed on the protection door body 121, and when the limit block 14 abuts against the protection door body 121, the limit block 14 is located in the receiving groove 1216.

In a possible design, referring to fig. 2, when there are a plurality of protective door assemblies 12 in the device 1, in order to ensure the strength of the guide rails 13, a reinforcing rib 16 is further provided in the carrying seat 11 and arranged along the width direction of the USB socket, the reinforcing rib 16 is located between two adjacent guide rails 13, and the two adjacent guide rails 13 do not belong to the same protective door assembly 12.

The guide rail 13, the stopper 14 and the reinforcing rib 16 may be integrally formed with the bearing seat 11, or may be connected by splicing, such as adhesion.

Based on the structure, the USB plug can enter the USB socket when being inserted positively or reversely. However, in actual use, the forward insertion and the backward insertion of the USB plug will directly affect whether the USB plug can be used with the USB socket.

The positive insertion means that a USB plug can enter a USB socket through a USB opening on the socket panel to realize the insertion of the USB plug and the USB socket; reverse insertion means that after the USB plug enters the USB opening, the solid part of the USB plug abuts against the tongue piece part of the USB socket, so that the USB plug cannot be inserted into the USB socket. The limitation of the forward insertion and the reverse insertion shows that the USB plug can be inserted into the USB socket only when the forward insertion is carried out; and when the USB plug is reversely plugged, the USB plug cannot be plugged with the USB socket.

In order to further protect the USB socket, referring to fig. 1-3, the apparatus 1 for protecting the USB socket according to the embodiment of the present application further includes a stopper assembly 15, a side of the protection door body 121 close to the first elastic buffer component 122 has a groove 1212, and the stopper assembly 15 is located in the groove 1212 and can elastically move along the insertion direction of the USB plug 3.

Referring to fig. 5-7, when the stopper member 15 is configured to enter the USB plug 3 into the USB opening 21 in the forward-insertion posture, the stopper member 15 abuts against the solid portion 31 of the USB plug 3, and with the continuous insertion of the USB plug 3, the stopper member 15 can be pushed to move away from the socket panel 2 and move along the length direction of the USB socket along with the protective door body 121 until the protective door body 121 moves to the position where the USB socket is exposed, and the USB plug can enter the USB socket.

Referring to fig. 8, when the stopper assembly 15 is configured to enter the hollow portion 32 of the USB plug 3 in the reverse insertion posture into the USB opening 21, the shutter body 121 at this time may receive a pushing force in the insertion direction of the USB plug 3, and the pushing force may be decomposed into a force in the insertion direction of the USB plug and a force F1 (indicated by black arrows in fig. 8) in the length of the USB socket and in the direction toward the first elastic buffer member 122, and the stopper assembly 15 may move together with the shutter body 121 in the length of the USB socket and in the direction toward the first elastic buffer member 122 under the action of the force F1. However, since the stopper assembly 15 enters the hollow portion 32 of the USB plug 3 and the USB opening 21 on the receptacle panel 2 restricts the USB plug 3 in place, while the stopper assembly 15 moves together with the protective door body 121 along the length of the USB socket and in the direction of the first elastic buffer element 122, the side wall of the USB opening 21 provides a force F2 (indicated by a black arrow in fig. 8) against the first elastic buffer element 122 to the inner side wall of the hollow portion 32, the force F2 acts on the stopper assembly 15 to prevent the stopper assembly 15 from moving along the length of the USB socket and in the direction of the first elastic buffer element 122, the force F2 acts to counteract the force F1 to prevent the stopper assembly 15 and the protective door body 121 from moving along the length of the USB socket and in the direction of the first elastic buffer element 122, and thus, a self-lock is formed between the stopper assembly 15 and the protective door body 121, therefore, the USB plug can not enter the USB socket, and the USB plug is plugged with the USB socket.

Therefore, when the block assembly 15 is additionally arranged in the device 1, the USB plug 3 is limited to be inserted into the USB socket only in the forward insertion posture, the insertion speed of the USB plug can be effectively reduced or the insertion force exerted on the USB plug can be reduced when the USB plug 3 is inserted into the USB socket, and when the USB plug 3 enters in the reverse insertion posture, self-locking is formed between the block assembly 15 and the protective door body 121, so that the USB plug 3 cannot be inserted into the USB socket.

In one possible design, referring to fig. 2 or 3, the stop assembly 15 includes a stop body 151, a projection 152, and a second resilient buffer element 153. One end of the second elastic buffer device 153 is connected to the protective door body 121, and the other end is connected to the stopper body 151. The protrusion 152 is located on a side of the stopper body 151 facing the socket panel 2, an orthographic projection of the protrusion 152 on the stopper body 151 has an overlapping region with an orthographic projection of the hollow portion 31 on the stopper body 151 when the USB plug 3 is inserted, and the orthographic projection of the protrusion 152 on the stopper body 151 is located within an orthographic projection of the hollow portion 32 on the stopper body 151 when the USB plug 3 is inserted backwards.

By providing the second elastic buffer means 153, the stopper body 151 is allowed to elastically move in the insertion direction of the USB plug 3. Here, the second elastic buffer device 153 may be located in the groove 1212. After the solid portion 31 of the USB plug 3 enters the USB opening 21, it may contact the protrusion 152 and push the protrusion 152, so that the second elastic buffer element 153 is compressed.

When the solid portion 31 is separated from the protrusion 152, the second elastic buffer device 153 can push the stopper body 151 to return to the state when the USB plug 3 is not inserted under the action of its own elastic force, so as to ensure the recycling of the device 1.

Alternatively, the second elastic buffer device 153 may be a spring or an elastic plastic pad. Wherein, the preferred spring, the preparation of convenient material and the elasticity coefficient of settlement.

Taking the second elastic buffer 153 as an example of a spring, the elastic coefficient of the spring may determine how easily the solid portion 31 of the USB plug 3 presses the protrusion 152. Wherein, when the spring coefficient of the selected spring is smaller, the user can push the protrusion 152 with smaller force; when the spring constant of the selected spring is large, the user needs to use a large force to push the protrusion 152.

Further, referring to fig. 4, the groove bottom of the groove 1212 and the stopper body 151 are respectively provided with a third connecting column 1218 and a fourth connecting column 155, and two ends of the spring are respectively sleeved on the third connecting column 1218 and the fourth connecting column 155, so that one end of the spring is connected to the protective door body 121, and the other end of the spring is connected to the stopper body 151. In addition, other implementations for the fixation of the spring are possible. For example, in some embodiments, a third fixing groove (not shown) and a fourth fixing groove (not shown) are respectively formed on the groove bottom of the groove 1212 and the stopper body 151, and both ends of the spring may be fixed in the third fixing groove and the dead-ground fixing groove.

Alternatively, the two ends of the second elastic buffer member 153 may be adhered to the groove bottom of the groove 1212 and the stopper body 151, respectively, by an adhesive.

Optionally, the number of the second elastic buffer devices 153 is at least one, and may also be multiple, and is not limited herein. For example, referring to fig. 4, the number of the second elastic buffer devices 153 is one.

In one possible design, referring to fig. 2, the side of the protrusion 152 facing the socket panel 2 has a second inclined surface 1521, and the distance between the second inclined surface 1521 and the socket panel 2 gradually increases from the side of the second inclined surface 1521 close to the first elastic buffer element 122 to the side far from the first elastic buffer element 122. That is, the second inclined surface 1521 is aligned with the slope direction of the first inclined surface 1211.

Optionally, the plane where the second inclined surface 1521 is located is parallel to the plane where the first inclined surface 1211 is located, and referring to fig. 6, after the protrusion 152 moves a certain distance along the length direction of the USB socket along with the protection door body 121, since the protrusion 152 also moves a certain distance in the direction away from the socket panel 2, the second inclined surface 1521 may be coplanar with the first inclined surface 1211, so as to facilitate pushing the protection door body 121.

Optionally, referring to fig. 3, the side of the protrusion 152 facing the socket panel 2 further has a contact surface 1522, the extending direction of the contact surface 1522 is perpendicular to the inserting direction of the USB plug 3, and there is an intersection with the second inclined surface 1521, so that the protrusion 152 is in surface-to-surface contact with the solid portion 31, and it is ensured that the protrusion 152 can stably move away from the socket panel 2.
