Abstract

The present invention relates to a socket protection door assembly, in which a protection door member is moved by inertia when a socket is subjected to an external impact such as a drop or a fall. At this time, the protective door member starts to slide in the first direction. When it slides, the first guide slope also moves by a distance b perpendicular to the first direction. Since the condition a > b is satisfied, when the protective door member tries to slide further in the first direction, the first stopper portion restricts the sliding of the protective door member, ensuring that the protective door member does not come off the housing. Thus, even after an external impact, the protection door can effectively protect the socket hole, preventing the protection door member from being detached from the inside of the case.

Referring to fig. 1-10, an embodiment of the present invention provides a socket protection door assembly, the socket protection door assembly 100 includes:

a housing 110, in which a first movable groove 110a, a second movable groove 110b, and a third movable groove 110c connecting the first movable groove 110a and the second movable groove 110b are formed, a first stopper 111 is provided on the housing 110, a first sidewall 110d is provided on the third movable groove 110c near the first stopper 111, and a distance from one end of the first stopper 111 far from the first sidewall 110d to the first sidewall 110d is denoted as a;

A protection door member 120 having one end disposed in the first movable groove 110a and the other end extending into the second movable groove 110b through the third movable groove 110c, the protection door member 120 being slidable in a first direction a with respect to the housing 110, the protection door member 120 being provided with a first guide slope 120a;

when the protection door member 120 falls, the protection door member 120 slides along the first direction a, and the movement distance of the first guiding inclined surface 120a along the direction perpendicular to the first direction a is denoted as b, which satisfies the following relationship: a > b; the first direction a is a direction from an end of the first stop portion 111 away from the first sidewall 110d to the first sidewall 110 d.

In the present embodiment, when the socket is subjected to an external impact such as a drop or a fall, the protection door member 120 is moved by an inertial action. At this time, the protective door member 120 starts to slide in the first direction a. As it slides, the first guide slope 120a also moves by a distance b perpendicular to the first direction a.

Since the condition a > b is satisfied, when the protection door member 120 attempts to slide further in the first direction a, the first stopper 111 limits the sliding of the protection door member 120, ensuring that the protection door member 120 does not come off the housing 110. In this way, even after an external impact, the protection door can effectively protect the socket hole, preventing the protection door member 120 from being detached from the inside of the case 110.

It should be noted that, the housing 110 and the movable groove, the housing 110 is a main structure of the protection door 120, and the first movable groove 110a, the second movable groove 110b and the third movable groove 110c provide a sliding channel for the protection door 120. The protection door member 120 is allowed to slide as necessary, and to respond and possibly automatically reset when an external impact is received.

The movable groove allows the protective door member 120 to slide within the housing 110, thereby responding to an external force and realizing an automatic reset or locking function.

The first stopper 111 is of a rectangular strip-shaped design for restricting the sliding range of the protective door member 120. It is ensured that the protection door member 120 is maintained in the housing 110 even under external impact, thereby ensuring safety of the socket.

The protection door member 120 effectively prevents children or other misoperators from inserting objects into the socket, and improves the safety of the socket.

Since the impact may move the protection door member 120 along the first direction a, and at the same time, the protection door member 120 may move along the direction of gravity under the action of gravity, so that the actual movement length of the first guiding inclined surface 120a may be longer than the movement distance in the first direction a, the conventional protection member is separated from the housing 110 due to the absence of the limit of the first stop portion 111, and the protection door member 120 cannot be protected.

In at least one embodiment of the present application, the protective door member 120 includes:

a first two-stage protection door 121, which is partially disposed in the first movable slot 110a, and the other part extends into the third movable slot 110 c;

a two-stage belt grounding protection door 122, which is partially disposed in the second movable slot 110b, and the other part extends into the third movable slot 110c, wherein one end of the two-stage belt grounding protection door 122 is provided with the first guiding inclined plane 120a;

and a first return spring 123 disposed in the third movable slot 110c, wherein two ends of the first return spring 123 are respectively abutted against the first two-stage protection door 121 and the two-stage grounded protection door 122.

In at least one embodiment of the present application, the two-stage belt grounding protection door 122 is provided with a first abutment portion 1221, the first abutment portion 1221 is located in the third movable groove 110c, one side of the first abutment portion 1221 abuts against the first return spring 123, and the other side of the first abutment portion 1221 can abut against the first side wall 110 d;

when the protection door member 120 falls, the protection door member 120 slides along the first direction a, and the projection of the first stop portion 111 in the second direction B, which is the direction from the first stop portion 111 to the first contact portion 1221, blocks the first contact portion 1221.

In at least one embodiment of the present application, the housing 110 is further provided with a second stop portion 112, the third movable slot 110c is further provided with a second side wall 110e, the second side wall 110e is opposite to the first side wall 110d, and the second stop portion 112 is disposed on the second side wall 110 e;

the first two-stage protection door 121 is provided with a second abutting portion 1211, the second abutting portion 1211 is located in the third movable groove 110c, one side of the second abutting portion 1211 abuts against the first return spring 123, and the other side of the second abutting portion 1211 can abut against the second side wall 110 e;

when the protection door member 120 falls, the protection door member 120 slides along the first direction a, and the projection of the second stopper 112 in the second direction B shields the second abutment 1211.

Referring to fig. 1 to 10, in the present embodiment, when no plug is inserted, the first and second contact portions 1211 of the protection door contact the corresponding first and second sidewalls 110d and 110e, and the protection door member 120 is maintained in a closed state.

When an external force (e.g., a plug) is applied, the protective door member 120 is pushed to slide in the first direction a.

At this time, projections of the first stopper 111 and the second stopper 112 in the second direction B block the first abutting portion 1221 and the second abutting portion 1211, respectively, and the first stopper 111 and the second blocking portion block the first abutting portion 1221 and the second abutting portion 1211, respectively, thereby preventing the protective door member 120 from being detached from the housing 110.

Once the plug is pulled out, the first return spring 123 will return the protection door to its original closed position.

The first stopper 111 and the second stopper 112 mainly ensure that the protective door member 120 slides within a specific range and is prevented from being separated from the housing 110.

The stability and durability of the socket are increased, ensuring that it is not damaged by excessive sliding or impact.

The internal return springs and other parts are protected to ensure that they continue to function properly for the intended life.

When the plug is inserted, it pushes the shutter member 120 to slide, and the first and second abutment portions 1211 are moved away from their initial positions.

Once the plug is pulled out, the first return spring 123 will return the door to its original closed position, restoring its safety protection function.

the shell 110 is provided with a first limiting part 113 and a second limiting part 114, and the first limiting part 113 and the second limiting part 114 are arranged in the second movable groove 110 b;

when the first guiding inclined surface 120a abuts against the first limiting portion 113, the second guiding inclined surface 122d abuts against the second limiting portion 114, so as to block the three insertion holes 110f;

the first guide inclined surface 120a and the second guide inclined surface 122d are used for abutting with an external socket pin to drive the two-stage belt ground protection door 122 to slide, so that the first through slot 122a, the second through slot 122b and the third through slot 122c are respectively communicated with the three insertion holes 110 f.

Referring to fig. 1 to 10, in the present embodiment, when the plug is not inserted, the first guiding inclined surface 120a abuts against the first limiting portion 113, and the second guiding inclined surface 122d abuts against the second limiting portion 114, so that the first through slot 122a and the third through slot 122c are both blocked, thereby avoiding erroneous insertion.

When the plug is inserted, its pins abut against the first and second guide slopes 122d, driving the two-stage belt ground protection door 122 to slide. The first, second and third through grooves 122c gradually communicate with the three insertion holes 110f as the protection door slides, allowing the plug to be smoothly inserted.

Wherein the first through slot 122a, the second through slot 122b and the third through slot 122c of the two-stage strip-ground protection gate 122 provide a passage for the socket pins to penetrate through so that the external socket pins can enter the socket interior contact conductive portions through these slots when the socket is required to be used.

The safety is enhanced. When no plug is inserted, these through grooves are shielded by the protective door member 120, thereby avoiding false touches or other object insertion.

The first guide inclined surface 120a and the second guide inclined surface 122d abut against the first guide inclined surface 120a and the second guide inclined surface 122d to drive the protection door member 120 to slide when the external double-plug socket pin is inserted.

The protective door member 120 is opened, allowing the plug to be smoothly inserted.

Referring to fig. 1 to 10, in the present embodiment, in the initial state, the first surface 122e abuts against the inner wall of the second movable slot 110b, and when the socket is impacted or there is a plug connection, the two-stage belt ground protection door 122 moves to generate a certain deflection, so that the second surface 122f abuts against the inner wall of the second movable slot 110b, and the protection door member 120 moves under the inertia effect. At this time, the protective door member 120 starts to slide in the first direction a. As it slides, the first guide slope 120a also moves by a distance b perpendicular to the first direction a.

Since the condition a > b is satisfied, when the protection door member 120 attempts to slide further in the first direction a, the first stopper 111 limits the sliding of the protection door member 120, ensuring that the protection door member 120 does not come off the housing 110. In this way, even after an external impact, the protection door can effectively protect the socket hole, preventing the protection door member 120 from being detached from the inside of the case 110.

Wherein, the first surface 122e is engaged with the second surface 122f, and the first surface 122e and the second surface 122f are disposed near the inner wall of the second movable slot 110 b.

In at least one embodiment of the present application, the housing 110 is further provided with a fourth movable slot 110h, a second two insertion holes 110i, and a fifth movable slot 110j communicating with the fourth movable slot 110h, the second two insertion holes 110i are located in the fourth movable slot 110h, the housing 110 is further provided with a third stop portion 117, and the third stop portion 117 is located in the fifth movable slot 110 j;

the socket protection door assembly 100 further includes:

a second two-stage protection door 130 provided with a third abutting portion 131, wherein the second two-stage protection door 130 is partially accommodated in the fourth movable slot 110h, and the third abutting portion 131 extends into the fifth movable slot 110j through the fourth movable slot 110 h;

A second return spring 140 provided in the fifth movable groove 110j, one end of which abuts against the fifth movable groove 110j and the other end of which abuts against the third abutting portion 131, the second two-stage protection door 130 being identical to the first two-stage protection door 121;

wherein, in the vertical direction from the third stop portion 117 to the third abutting portion 131, the projection of the third stop portion 117 always shields the third abutting portion 131; the external plug abuts against the second two-stage protection door 130 to drive the second two-stage protection door 130 to move, so that the second two-stage protection door 130 does not block the second two-stage insertion holes 110i.

In the present embodiment, in the initial state, the second two-stage protection door 130 is in the closed state due to the action of the second return spring 140, shielding the second two insertion holes 110i.

When the pin of the plug contacts the second two-stage protection gate 130, it drives the second two-stage protection gate 130 to slide along the fourth movable groove 110h, and the third abutting portion 131 is pushed in the fifth movable groove 110j while interacting with the second return spring 140.

After the plug is fully inserted, the second two jacks 110i are fully opened.

When the plug is pulled out, the second return spring 140 will return the second two-stage protection door 130 to block the second two jacks 110i again.

So that the socket is completely closed when the plug is not inserted, thereby avoiding possible safety risks. When the plug needs to be connected, it can be easily inserted and a connection can be established. Providing a higher level of security and convenience.

When the housing 110 receives an external impact (fall), the second two-stage protection door 130 may be pushed by gravity, causing the third abutting portion 131 to attempt to move within the fifth movable groove 110 j.

Since the projection of the third stop 117 always obstructs the third abutment 131, it acts as a "barrier" preventing excessive movement of the third abutment 131, ensuring that the second two-stage protection door 130 does not disengage from the housing 110.

Once the external impact is over, the second two-stage protection door 130 is restored to its original position due to its structure and the presence of the second return spring 140.

The design of the third stop 117 ensures that its projection always obscures the third abutment 131 in its perpendicular direction to the third abutment 131, so that the third abutment 131 is blocked by the third stop 117 when it tries to move out of the fifth movable slot 110j due to an external force.

The presence of the third stopper 117 ensures that the second two-stage protection door 130 is not detached from the housing 110 by impact under the external force, thereby improving the stability and durability of the entire structure.

The risk of socket exposure caused by the falling-off of the second two-stage protection door 130 due to external impact is avoided, and the safety of the product is further increased.

Wherein, the first stop portion 111 and the second stop portion 112 have the same length.

It should be noted that, the first movable slot 110a, the second movable slot 110b, and the third movable slot 110c are disposed on the same surface of the housing 110, and the fifth movable slot 110j and the fourth movable slot 110h are disposed on the same surface of the housing 110 and adjacent to the side where the first movable slot 110a is disposed.

The second two-stage protection gate 130 is arranged perpendicular to the first two-stage protection gate 121, and the first two-stage protection gate 121, the second two-stage protection gate 130 and the two-stage grounded protection gate 122 are arranged in a concentrated manner, so that the volume of the socket is reduced.

The fourth movable slot 110h, the second two insertion holes 110i and the fifth movable slot 110j of the housing 110 provide a sliding and positioning space for the second two-stage protection door 130. The second two jacks 110i provide insertion channels for pins of an external plug.

The third stopper 117 positions and limits the sliding range of the second two-stage protection door 130, ensuring its normal operation.

So that the socket is more stable in the use process.

The second two-stage protection door 130 and the third abutting portion 131 interact with the second return spring 140 in the fifth movable slot 110j to drive the protection door to open or close when the external plug contacts and pushes the second two-stage protection door 130.

The socket is ensured to be closed when no plug is provided, but can be easily inserted when the plug needs to be accessed.

The second return spring 140, when the plug is pulled out from the socket, returns the second two-stage protection door 130 to the original position, thereby closing the second two-stage insertion holes 110i again. The socket is kept closed when not in use, and false touch is prevented.
