Description

Power distribution device with safety protection function

Technical Field

The invention relates to the field of electrical equipment, in particular to a power distribution device with a safety protection function.

Background

Power distribution devices currently used in residential and commercial buildings consist of a cavity and electrical connectors together. The power distribution device comprises a cavity, the cavity is provided with an opening, a conductor is arranged in the cavity and used for being electrically connected with an external power supply, and when the power distribution device is used, the electric connector is inserted into the cavity through the opening and is electrically connected with the conductor in the cavity.

In the prior art, the difficulty of the power distribution device is that the opening is exposed and the opening gap is large, which affects the safety and the aesthetic property of the power distribution device, and no complete solution is provided so far.

The invention discloses a power distribution device with a safety protection device, and aims to solve the problem through a new structural design scheme.

Disclosure of Invention

The invention aims to provide a power distribution device with a safety protection function. The power distribution device is protected both in the free and in the use state.

In order to achieve the purpose, the technical scheme of the invention is as follows:

in one aspect, the present invention provides a power distribution device with a safety protection function, including a cavity, a conductor disposed in the cavity, and an opening disposed on the cavity, and characterized in that: also comprises a safety protection device which comprises a safety protection belt or a protection baffle, one end of which is connected directly or indirectly via an elastic element in the cavity, and which, in an original state, the safety protection device can close the opening by the elasticity of the safety protection device or the elastic element, and in a use state, the safety protection device deforms and/or displaces under the action of external force to open the opening and returns to the original state after the electric connector is pulled out of the opening, when the safety protection device is a safety protection belt, the safety protection belt is arranged to be an elastic structure body, and the rigidity of the safety protection belt at least at the contact part with the electric connector in the power distribution device is different in each direction, thereby overcoming various resistances encountered when the electrical connectors of different structures are inserted into and pulled out of the openings by using the arrangements with the rigidity being different in each direction.

Here, stiffness refers to the ability of the safety belt to resist elastic deformation when the electrical connector enters the opening and contacts the safety belt, which is made up of an elastic structure. The magnitude of the stiffness depends on the geometry (i.e., structure) and type (i.e., modulus of elasticity) of the safety guard band; the different rigidity directions mean that the rigidity results of the safety protection belt in all directions are different.

The surface of the safety protection device, which is contacted with the electric connector in the power distribution device, is set as a front surface, and the back surface of the front surface is set as a back surface.

Each part of the safety protection belt is divided according to functions and comprises a fixed end, a supporting end and a movable end which are connected in sequence; the fixed end is used for fixing the safety protection belt on the power distribution device; the supporting end is arranged between the fixed end and the movable end and is used for supporting the safety protection belt to keep the original state and supporting the movement of the movable end; the movable end is used for arranging a convex-concave structure and is pressed down under the action of external force and returns to the original state after the external force is eliminated.

The convex-concave structure is arranged on at least the front surface of the safety protection belt and can also be arranged on the back surface of the safety protection belt.

The minimum value of the height of the convex part of the convex-concave structure is 0.05 μm, and the maximum value of the height is 6 mm; wherein the height refers to the shortest distance from the deepest part of the recess to the most protruded part of the protrusion of the projection-recess structure. When the minimum height of the convex part is less than 0.05 μm, the surface of the safety protection belt tends to be smooth, so that the rigidity is insufficient, and the function of the safety protection belt cannot be realized; when the maximum height of the convex part is larger than 6mm, the safety protection belt loses necessary elasticity and cannot be bent, and accordingly the function of the safety protection belt cannot be achieved.

Preferably, the relief structure is provided as a longitudinal relief structure;

optionally, the cross section of the fixing end is a triangular end.

Optionally, the movable end is provided with at least one split support structure, and the split support structure comprises a plurality of elastic sheets which are sequentially arranged and independently movable;

when the safety protection area sets up components of a whole that can function independently bearing structure: when the electric connector guide body is inserted into the opening, the guide body presses the elastic sheet inserted into the corresponding position downwards into the cavity, and other elastic sheets which are not pressed are still in the original state; when the electric connector is pulled out of the opening, the elastic sheet is released from pressure and returns to the original state by elasticity.

Preferably, the safety protection device comprises two safety protection belts or two protective baffles, and the two safety protection belts or the two protective baffles are arranged on two sides of the width direction of the opening in a side-by-side manner.

In another aspect, the power distribution device further includes an electrical connector, and the current carrier of the electrical connector enters the opening through the safety guard band and is electrically connected to the conductor.

By adopting the technical scheme, the invention has the beneficial effects that:

1. due to the arrangement of the safety protection device, the opening can be shielded by the elasticity provided by the safety protection device or the elastic element in the original state, and the conductor can be exposed by deformation and/or displacement under the action of external force in the use state, so that the opening can be shielded under the condition of not influencing the normal use of the electric connector, and dust, water and the like can be effectively prevented from entering the cavity;

2. when the electric connector is inserted into the opening, the non-pressed safety protection belt part is still in the original state to protect the opening.

3. The rigidity difference is utilized to overcome various resistances encountered when the electric connector with different structures is inserted into and pulled out of the opening.

As shown in fig. 32, another configuration of a split support structure 600 provided on safety harness 100 is presented.

In this embodiment, the split supporting structure 600 is configured as an interval type split supporting structure 602, and the interval type split supporting structure 602 is different from the compact type split supporting structure 601 in that: the distance between the elastic sheets 603 is greater than that of the compact split support structure 601, and because the distance is greater, when a certain elastic sheet 603 moves, other elastic sheets 603 can not be interfered, so that the independent movement effect of each elastic sheet 603 is better.

In addition, in this embodiment, the notches 604 are disposed at two sides of each elastic sheet 603 near the supporting end 104, so that the elastic sheets 603 can move independently.

Example 31

In order to achieve similar technical effects to those of embodiments 29 and 30, in this embodiment, a plurality of safety devices (i.e., safety guard bands 100) may be arranged in sequence along the length direction of the opening 701.

So set up, during the use: in an original state, the safety protection belt 100 is in a shielding state for the opening 701, when the current carrier 801 of the electrical connector 800 is inserted into the opening 701, the safety protection belt 100 at a corresponding position is pressed into the cavity to open the opening 701, and the unstressed safety protection belt 100 is still in the original state to shield the opening 701; after current carrier 801 of electrical connector 800 is pulled out of opening 701, safety guard band 100, which is pressed down, automatically returns to its original state by its elastic action.

Example 32

As shown in fig. 33, a cross-sectional structure of the power distribution apparatus in an original state where the safety guard band 100 is installed on both sides of the opening 701 is presented.

In this embodiment, when the width of the opening 701 is larger, the safety belt 100 adapted to the width may not provide enough elastic force, so that the opening 701 may not be completely shielded. Accordingly, in the present embodiment, the safety guard bands 100 are disposed on both sides of the opening 701 of the power distribution apparatus. The safety guard bands 100 on both sides are arranged in a side-by-side manner on both sides in the width direction of the opening 701. So set up for safety protection area 100's width size can be reduced to make its elasticity that provides can its effectual support to its shelter from opening 701.

Example 33

Fig. 34 shows a schematic view of the electrical connector 800 inserted into the opening 701 with the safety guard bands 100 on both sides. In this embodiment, the safety guard bands 100 are installed on both sides of the power distribution device opening 701 in the width direction, and the safety guard bands 100 on both sides are pressed down and naturally bent into the cavity 700.

Example 34

It differs from any of the above embodiments in that: in this embodiment, the safety guard may be indirectly connected to the cavity 700 through the elastic element 301, and it is understood that the safety guard in this embodiment need not be configured as the safety guard band 100 of an elastic structure, but may be a protective shield 300 made of hard material such as plastic, wood, etc., as shown in fig. 35.

The elastic element 301 is preferably configured as a spring, for example, a mounting groove is formed on a side surface of the protective barrier 300 away from the opening 701, one end of the elastic element 301 is fixedly mounted in the mounting groove, and the other end of the elastic element is fixedly connected to an inner side wall of the cavity 700. Also, since the guard flap 300 generally has a certain length, the guard flap 300 is configured to be coupled to the cavity 700 by two or more elastic members 301, as shown in fig. 36.

In the use state, the shielding baffle 300 is displaced by an external force (a deflecting motion with the elastic element 301 as the origin), so that the opening 701 is opened to facilitate the insertion of the current carrier 801 of the electrical connector 800. When the elastic member 301 is a coil spring, it is subjected to bending deformation, and when the elastic member 301 is a torsion spring, it is subjected to torsional deformation.

Also, when there are two shielding plates 300 arranged in a side-by-side manner, it is preferable to provide an inclined surface on the top surface of the butt joint of the two shielding plates 300 so as to guide the current carrier 801 on the electrical connector 800 to push the two shielding plates 300 open.
