Description

TECHNICAL FIELD

[0001] The present application belongs to the field of electrical technology, and particularly relates to a locking control component of a waterproof socket, a safety socket module, a power strip and a mobile cable reel. BACKGROUND

[0002] The waterproof socket is a socket that overcomes the problem that water easily enters the socket from the socket hole and causes electric shock and short circuit accidents. The use scenarios of the waterproof socket are more and more at present, such as household waterproof sockets, street lamp waterproof sockets, industrial waterproof sockets and the like. The safety socket module disclosed in the prior Chinese patent CN111682343B is provided with a locking control component arranged in a compartment and aligned with the socket hole, which is used to clamp the pin of the plug of an electrical appliance and bias the waterproof electrical connection switch when the pin is inserted into the socket hole, and is separated from the pin and resets the waterproof electrical connection switch when the pin is pulled out of the socket hole. In the patent document, the biasing refers to lateral or outward extrusion. The lateral or outward extrusion can be caused by the lateral movement and / or outward rotation of the locking control component when the pin is inserted into the socket hole. The waterproof electrical connection switch comprises an isolation waterproof compartment and a movable contact piece and a static contact piece arranged opposite to each other in the interior of the waterproof capsule. The isolation waterproof compartment is configured as a fully sealed structure, and the contact surface of the locking control component that is biased can be elastically deformed. The movable contact piece is configured to contact the static contact piece to turn on the waterproof electrical connection switch by the biasing of the locking control component when the pin is inserted into the socket hole, and to move away from the static contact piece to turn off the waterproof electrical connection switch by the resetting of the locking control component when the pin is pulled out of the socket hole. The safety socket module solves the waterproof problem of the socket, and has good waterproof effect.

[0003] The two locking control components involved in the patent document are as follows. The first locking control component is that when the pin is inserted, the pin touches the second curved portion, the second curved portion moves laterally by a distance, and the first curved portion is in contact with the waterproof electrical connection switch, which is transmitted to the movable contact piece in the waterproof electrical connection switch. The distance is just right to make the movable contact piece and the static contact piece in good contact. That is, the deformation of the first curved portion generates a pushing force caused by the deformation of the second curved portion. However, the pushing force is insufficient in actual use, and in order to increase the pushing displacement, the curved surface of the first curved portion directly contacts the waterproof electrical connection switch, which may cause damage to the waterproof capsule.

[0004] The second locking control component is that the cross section of the pushing piece is configured as a generally V-shaped opening downward, the top end is a hinge point, one side edge is close to the socket hole, and the other side edge is covered with an insulating bushing and abuts against the waterproof electrical connection switch. The structure causes the defect of low stability of movement by the hinged way. In particular, the pushing piece forms a contact surface in contact with the waterproof capsule, and the end of the pushing piece must form a flat surface, not an arc surface or an angular surface, which reduces the displacement generated by the deformation, so that the pushing displacement of the structure is not ideal.

[0036] The embodiment further illustrates the present application, and if no special description, the connection described in the embodiment can be direct connection or indirect connection.

[0037] As shown in Figure 1 , a waterproof socket lock control component is made of conductor material, and the socket lock control component comprises: a pair of oppositely arranged fixed clamping pieces 1, a pair of oppositely arranged support pieces 2, a pair of push dial pieces and a pair of oppositely arranged push pieces 7.

[0038] As shown in Figure 4 , the gap between the pair of fixed clamping pieces 1 is the pin hole 3 of the socket. In one scheme, the fixed clamping piece 1 comprises a vertical plate 9, an inward plate 10 and a guide plate 11, the inward plate 10 is inclined inward from the upper edge of the vertical plate 9, and the guide plate 11 is inclined outward from the upper edge of the inward plate 10. The pair of fixed clamping pieces 1 are oppositely arranged, the two guide plates 11 form an opening with gradually increasing angle upward and are connected to the two inward plates 10, and the two inward plates 10 form an opening with gradually increasing downward opening and are connected to the two vertical plates 9. Through the above structure, it is convenient to guide the pin to be inserted and stably inserted in the hole.

[0039] In a preferred scheme, the included angle of the opening with gradually increasing angle upward between the two guide plates 11 is 100-110 degrees, preferably 107 degrees.

[0040] As shown in Figure 5 , the pair of oppositely arranged support pieces 2, the planes where the support pieces 2 and the fixed clamping pieces 1 are located are perpendicular to each other.

[0041] In one scheme, the horizontal along 6 of the support piece 2 on which the push dial piece is installed is the bottom edge of the opening on the support piece 2, the opening is a rectangular port downwardly connected to a trapezoidal port with short upper and long lower, and the upper edge of the support piece 2 is gradually inclined downward from both sides of the rectangular port opening. The shape of the opening is matched with the shape of the pair of fixed clamping pieces 1 and forms an opening capable of stably installing the inner dial piece 4 and the outer dial piece 5, and the shape can avoid the opening with gradually increasing angle upward between the two guide plates 11, so that the space utilization is more reasonable.

[0042] In a preferred embodiment, the angle between the inclined side of the trapezoidal opening and the bottom side of the trapezoidal opening as the lateral edge 6 of the support sheet 2 is 20-40 degrees, preferably 30 degrees.

[0043] As shown in the figure, the pair of pusher tabs, including the inner tab 4 and the outer tab 5, are connected at the top and are angularly arranged at the bottom, i.e., the angle of the opening at the bottom is angular. Figure 6

[0044] In an embodiment, the angle between the inner tab 4 and the outer tab 5 of the pusher tab is 30-60 degrees, preferably 50 degrees. This angle affects the length of the push displacement, and in consideration of the compactness of the internal space of the socket, heat dissipation, and the safety distance of the static and dynamic contacts, it is determined to be the above-mentioned angle.

[0045] In an embodiment, the angle between the pusher tab 7 and each corresponding vertically arranged support sheet 2 is 0-50 degrees, preferably 0-30 degrees. The setting of this angle results in the push displacement formed by the pusher tab 7 being able to meet the distance requirement between the dynamic and static contacts in the waterproof capsule.

[0046] The pair of pusher tabs, including the inner tab 4 and the outer tab 5, are connected at the top and are angularly arranged at the bottom, i.e., the angle of the opening at the bottom is angular.

[0047] Figure 7 As shown in the figure, the pair of pusher tabs, including the inner tab 4 and the outer tab 5, are connected at the top and are angularly arranged at the bottom, i.e., the angle of the opening at the bottom is angular.

[0048] In a preferred embodiment, the pair of support sheets 2 are connected at the bottom and are vertically arranged. The pair of pusher tabs 7 are connected at the bottom, and the bottom of the pusher tab 7 is connected to the bottom of the support sheet 2. In the initial state, the pusher tab 7 and each corresponding vertically arranged support sheet 2 are vertically parallel to each other, and in the push state, the pusher tab 7 and each corresponding vertically arranged support sheet 2 are angularly arranged from the bottom to the top. Figure 3 ​As shown, in one aspect, the push piece 7 is also configured to be in contact with the pusher throughout the initial state and the pushed state of the pusher. In the initial state of the plug not being inserted, as shown in Figure 8 As shown, the push piece 7 is vertically parallel to the vertically arranged support piece 2 of the corresponding side, and the end of the outer pusher 5 of the pusher is in contact with the push piece 7, so that the outer pusher 5 of the pusher is substantially parallel to the vertically arranged support piece 2, and the inner pusher has the maximum rotatable angle. In the pushed state of the plug being inserted, i.e. during the pushing process, the angle of the opening-shaped opening between the push piece 7 and the vertically arranged support piece 2 of the corresponding side gradually increases from the bottom to the top, and after the push piece 7 biases the movable contact piece of the waterproof capsule and reaches the most biased point, the plug is in the terminal state of being fully inserted into the jack, the inner pusher of the pusher is substantially vertically parallel to the vertically arranged support piece 2 of the corresponding side, and the outer pusher has the maximum rotatable angle. Thus, all the pushing displacement of the pusher caused by the plug can be applied to the push piece 7, and the utilization rate of the pushing displacement of the push piece 7 is improved.

[0049] In one aspect, the inner pusher 4 and the outer pusher 5 of the pusher are arc-shaped at the pusher end 8, i.e. the end is outwardly convex (convex towards the push piece 7), and the convex part can provide a larger pushing force to the pusher. The inner pusher 4 and the outer pusher 5 of the pusher are outwardly convex at the pusher end 8, and the gap between the push piece 7 and the support piece 2 in the initial state is arranged such that the push piece 7 in the gap is in contact with the outwardly convex surface of the end of the outer pusher 5 of the pusher, and the edge of the end of the outer pusher 5 of the pusher is towards the support piece 2 and in contact with the support piece 2, as shown in Figure 7 In this case as well, not only the pushing force of the convex part is enhanced to push the push piece 7, but also the utilization rate of the pushing displacement of the push piece 7 is improved by the arrangement of the maximum rotatable angle.

[0050] From the above, the present application can solve the problem of non-ideal deformation and hinged displacement of the pushing piece by supporting the pushing piece 2 and the pusher with a swingable connection to limit the angle of the swing of the pusher. The stability during movement is higher with the swingable connection of surface contact than the hinged connection of point contact. Further, the present application realizes the surface contact of the pushing piece 7 and the waterproof capsule by the structure of the pushing piece, which is not easy to damage the waterproof capsule. The pushing piece does not directly contact the waterproof capsule, and the influence of the stability of the movement of the pushing piece on the capsule is reduced. The separation of the movement source structure and the contact structure avoids the phenomenon that the end of the pusher of the second lock control member must form a plane, and cannot form an arc surface or an angle surface, so that the displacement caused by deformation can still be better utilized, and the pushing displacement of the structure is more ideal. Of course, in one scheme, the pushing piece 7 is also configured to be pulled out of the socket by the pin, and the pusher is reset because it loses the force provided by the pin, so that the pushing piece 7 is separated from the waterproof electrical connection switch. The process is that the pusher loses the force provided by the pin, the elastic force of the movable contact of the waterproof capsule pushes the pushing piece 7, the pushing piece 7 pushes the outer pusher 5 of the pusher, and the end of the outer pusher is swung towards the supporting piece 2 to which it is clamped by a certain angle, so that the end of the inner pusher 4 of the pusher is swung away from the supporting piece 2 to which it is clamped by a certain angle and is reset.

[0051] As Figure 2 shown, in one scheme, the bottom of the pair of oppositely arranged fixed clamping pieces 1 is connected, the bottom of the pair of oppositely arranged supporting pieces 2 is connected, and the bottom of the pair of oppositely arranged pushing pieces 7 is connected. Each bottom is connected in layers in the longitudinal direction. In one preferred scheme, the bottom of the pair of oppositely arranged fixed clamping pieces 1 is in the first layer, the bottom of the pair of oppositely arranged supporting pieces 2 is in the second layer, and the bottom of the pair of oppositely arranged pushing pieces 7 is in the third layer. The bottoms of the three layers are connected by bolts at different height positions of the bolts.
