Abstract

There is provided a receptacle capable of reducing an impact caused by closing of a receptacle cover and preventing a breakage of the receptacle cover against a plurality of opening/closing motions. The receptacle cover 2 is attached to a shaft 32 and the shaft 32 is inserted through an insertion hole 33a of a damper member 33, so that the damper member 33 is provided pivotally relative to the shaft 32. When the receptacle cover 2 pivots, the shaft 32 pivots with the receptacle cover 2 integrally. Accordingly, the shaft 32 and the damper member 33 come into friction contact with each other. This provides sliding resistance between the damper member 33 and the shaft 32 to reduce a pivot speed of the receptacle cover 2, thereby reducing an impact occurred when the receptacle cover 2 comes into contact with a receptacle body.

Description

socket

The present invention relates to a socket having a cover that covers a pin insertion port.

Conventionally, an outdoor socket attached to an exterior wall such as a house is known. Such outdoor outlets, for example, have been used in outdoor lighting devices or the like, and are increasingly being used to charge electric vehicles in recent years.

In order to prevent water such as rainwater from penetrating into the pin insertion opening of such an outdoor socket, there is provided a socket cover disclosed in, for example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2005-158345), in which there is no pin When connected to an outdoor outlet, the pin insertion port (such as the "socket entry port" described in Patent Document 1) is closed with the cover (such as the "lid" described in Patent Document 1).

In the above-described conventional structure, the socket is housed in a case (such as the "cover body" described in Patent Document 1) in such a manner that its pin insertion opening is exposed, and the cover covers the socket of the socket. An insertion port, the cover being pivotally attached to the case via a pivot shaft. Further, the cover is biased to the cover closing direction (the direction in which the pin insertion opening is covered) by a biasing member such as a spring, so that the cover automatically closes when no pin is connected to the socket. Further, the convex sliding contact member is disposed in the cover, and the planar sliding contact member is disposed in the case. Since such sliding contact members rub against each other just before the cover is closed, the pivoting speed of the cover can be reduced. because Thereby, the cover damage and the large noise due to the impact caused by the closing of the cover can be suppressed.

However, in the above-described conventional structure, the sliding contact member needs to be disposed in both the case and the cover, which makes the case and the cover unsuitably bulky. Further, in order to lower the pivoting speed of the cover to an appropriate speed when the cover is closed, it is necessary to align the positions of the cover and the case so that the sliding contact members are in sliding contact with each other, and thus it is difficult to manufacture.

In view of the above, the present invention provides a socket that can be easily manufactured, which can reduce the impact caused by closing the cover.

According to an aspect of the present invention, a socket is provided, comprising: a socket body having a plug insertion surface, the plug insertion surface having a pin insertion opening, and a plug pin of the plug being detachably inserted into each of the plugs The pin insertion opening; the socket cover pivotable between a closed position of the plug insertion surface of the socket body and an open position of the plug insertion surface of the socket body exposed to the outside a support member pivotally supporting the socket cover relative to the socket body about a pivot shaft disposed at one end of the socket cover, the pivot shaft being fixed to the socket cover Pivoting with the socket cover; and a biasing member biasing the socket cover to the closed position, wherein the support member is provided with a damping member having a shaft hole, the pivot a rotating shaft to be inserted into and through the shaft hole, the damping member being applied from the biasing member to the socket cover by adding sliding resistance when the socket cover is pivoted relative to the support member The partial pressure is weakened.

According to such a configuration, the socket cover biased to the closed position is attached to the pivot shaft, and the damping member is attached to the pivot shaft for contact with the pivot shaft. Therefore, the closing force of the socket when the socket cover is pivoted to the closed position is weakened by the sliding resistance generated between the pivot shaft and the damping member. Therefore, the impact caused by closing the socket cover can be reduced. Further, since the damping member for adding the sliding resistance and the supporting member are disposed in an integrated manner, neither the socket body nor the socket cover is increased in size, which is different from the conventional socket. Furthermore, it is not necessary to align the damping member (unlike the conventional socket), whereby the socket can be easily assembled.

The support member supports the socket body when the socket body is mounted on the wall surface such that the plug insertion surface of the socket body is substantially face down and the socket cover is in the closed position The lower end portion of the socket cover. In the socket cover, a drain hole defining a gap between the socket cover and the support member may be disposed, and water flowing along a surface of the socket cover opposite to the socket body passes through the drain The holes are discharged to the outside.

According to such a configuration, in a state where the socket main body is mounted on the wall surface, the support member supports the lower end portion of the socket cover when the socket cover is closed. In the socket cover, a drain hole is formed to define a gap between the socket cover and the support member. Even (example For example, rainwater seeps into the space defined by the socket cover and the socket body (in this space, the pin insertion opening of the socket is provided), and the infiltrated water is discharged to the outside through the drain hole. Therefore, it is possible to avoid a malfunction such as a short circuit between the pin receivers due to the penetration of water into the pin insertion opening of the socket. Further, in the water penetrating into the space, water flowing downward along the surface of the socket cover opposite to the socket main body is discharged to the outside through the drain hole without reaching the support member. Therefore, it may be difficult for water to penetrate into the support member, and the damping member provided in the support member is prevented from being damaged by water.

Further, on a surface of the socket cover opposite to the socket body, ribs for guiding water flowing along the surface to the drain hole in a state where the socket cover is in the closed position are provided ( Rib).

According to such a configuration, on the surface of the socket cover opposite to the socket body, ribs for guiding water to the drain holes are provided. Such a configuration is allowed to direct water flowing along the surface to the drain hole. Therefore, it becomes difficult for water to penetrate into the support member, and the damping member provided in the support member is reliably prevented from being damaged by water.

Further, a waterproof sealing package may be disposed on a portion of the socket cover that is in contact with the socket body in a state where the socket cover is in the closed position.

According to such a configuration, since the waterproof sealed package is disposed on the socket cover, water can be prevented from penetrating into the space defined by the socket cover and the socket body.

In addition, in the plurality of opposing surfaces of the socket cover and the socket body In at least one, a cushioning member can be provided for reducing the impact that occurs when the socket cover is pivoted to the closed position.

According to such a configuration, since the cushioning member is disposed on at least one of the plurality of opposing surfaces of the socket cover and the socket body, the socket cover is less impacted by the closure of the socket cover than the socket cover without the cushioning member Reduce the ground more.

Further, in the socket cover, a holding member may be provided for holding the plug when the plug pin of the plug is inserted into the pin insertion opening to keep the plug pin inserted in the The state of the pin insertion port.

According to such a configuration, since the socket cover is provided with a holding member for holding the plug, even when the user removes his/her hand from the plug in a state where the plug pin is inserted into the pin insertion opening, The plug can be prevented from being disengaging automatically, whereby the state in which the plug blades are inserted into the pin/insert insertion opening can be maintained.

Accordingly, the present invention allows to provide a socket that can be easily manufactured and that reduces the impact caused by closing the socket cover.

The objects and features of the present invention will become more apparent from the description of the appended claims

As shown in FIG. 4, the socket block 5 is received in the protruding section 42 of the body 4. One portion of the socket block 5 is inserted into an insertion opening 42f serving as an insertion hole, and the insertion opening 42f is provided in the lower wall member 42c of the protruding portion 42. Specifically, the fixing member 51d of the socket case 51 is placed on the lower wall member 42c of the protruding portion 42. In a state where the connection exposed surface 51b and the side wall portion 51g of the fixing member 51d are in stepwise contact with the periphery of the insertion opening 42f, the socket block 5 is disposed with respect to the protruding portion 42 such that the exposed surface 51b is inserted through the insertion opening 42f exposed. In this state, the bottom surface of the lower wall portion 42c of the projecting portion 42 and the exposed surface 51b constitute the plug insertion surface of the socket main body.

The insertion opening 42f is configured to tilt upward as it extends forward. Therefore, the socket block 5 is attached to the protruding section 42 so as to protrude and tilt forward as it extends downward. The pin insertion opening 51a is formed on the bottom portion 51e1 of the recessed portion 51e in the socket case 51 such that the bottom portion 51e1 and the pin insertion opening 51a and the insertion opening 42f are inclined upward as they are extended forward.

The support member 3 is attached to the base 41 from its rear side such that the support step 31c protrudes through the insertion hole 41f. The support member main body 31 of the support member 3 is fixed to the base 41 from a rear side thereof by a plurality of mounting screws (not shown) which are inserted and passed through two mounting holes 31h drilled in the support substrate portion 31a (See Fig. 3A) and screwed with a screw hole 41h (see Fig. 2) formed in the rear surface of the base 41.

The insertion hole 31d of the support step 31c and the insertion hole 33a of the damping member 33. Since the grease is injected into the insertion hole 33a of the damping member 33, the shaft 32 can resist the damping member 33 to pivot by friction. On the other hand, since the shaft 32 is fitted into the insertion hole 21a of the pivot support member 21 by being pressed in, the socket cover 2 pivots together with the shaft 32. With such a configuration, the spring member 34a of the biasing spring 34 is spring-shaped from its initial state (i.e., when the socket cover 2 is in the closed position) with the socket cover 2 pivoted from its closed position. ) deformation. In this state, since the biasing spring 34 is restored to its original state by its elastic force, the socket cover 2 is biased to the closed position.

That is, the socket cover 2 is pivotable about the shaft 32 between a closed position in which the insertion opening 42f and the pin insertion opening 51a are covered from the lower side and an open position in which the socket cover 2 is away from the insertion opening 42f. Further, the socket cover 2 is biased to the closed position side by the biasing spring 34.

The sealed package 7 is disposed in the rear side of the base 41 of the main body 4 (as mentioned above), and the insulating frame 8 is housed in the rear side of the sealed package 7.

And 8b. Therefore, the sealed package 7 and the insulating mounting frame 8 are interposed between the main body 4 and the wall surface. Finally, these components are secured to the wall surface while maintaining their respective positions.

Next, referring to Figs. 5 to 8, the operation of inserting and removing the plug pin 91a of the plug 9 into and from the plug pin insertion opening 51a will be described.

First, referring to Fig. 5, the state of the socket 1 when the plug pin 91a of the plug 9 is not inserted into the pin insertion opening 51a will be described.

As shown in FIG. 5, with the socket cover 2 in the closed position, the socket cover 2 is retained to cover the lower surface of the protruding section 42 of the main body 4 and the lower edge of the decorative cover 6. Specifically, the socket cover 2 is substantially the same shape as the bottom opening of the decorative cover 6, and its front portion is in contact with the lower end surface of the decorative cover 6, and the rear portion thereof is in contact with the side surface of the decorative cover 6. Therefore, the socket cover 2 covers the decorative cover 6 from its lower side, and there is substantially no gap between the socket cover 2 and the decorative cover 6. In this state, the biasing spring 34 biases the socket cover 2 to the insertion opening 42f to prevent the socket 2 from pivoting downward due to, for example, its own weight and preventing the decorative cover 6 and the socket cover 2 from being There is a gap between them.

In general, in the case of providing a socket cover that can open and close the pin insertion port, the user may forget to close the plug after pulling out the plug. Cover cover. In the case of flushing the car near the outlet, for example, there is a possibility that water for rinsing the car penetrates into the pin insertion opening. However, in this embodiment, a biasing spring 34 is provided in the support member 3 to bias the socket cover 2 to the insertion opening 42f, thereby preventing unintentional opening of the socket cover 2.

Next, referring to Figures 6 and 7, the operation of inserting the plug pin 91a of the plug 9 into the pin insertion opening 51a will be described.

When the plug pin 91a of the plug 9 is inserted into the pin insertion opening 51a, first, the handle portion 2a of the socket cover 2 is held by hand, and then the socket cover 2 is pivoted downward to open the socket cover 2. From this state, the plug 9 is pushed up into the socket case 51 until the front surface 92a of the plug case 92 (on which the plug pin 91a is provided) hits the bottom 51e1 of the socket case 51, so that the plug pin 91a is inserted into the pin insertion. In port 51a.

Next, referring to Fig. 8, the state of the socket 1 when the plug pin 91a of the plug 9 is inserted into the pin insertion opening 51a will be described.

The pin holders 52 built in the socket block 5 are provided corresponding to the respective plug pins 91a of the plug 9. Specifically, the pin receiver 52 includes a voltage side pin holder that sandwiches the respective voltage side plug pins from both sides, and a floor side pin holder that sandwiches the ground plug pins 91a2 from both sides. Each of the voltage side pin holder and the floor side pin holder is elastically deformed to sandwich the respective plug pins 91a1 and 91a2. The restoring force caused by the elastic deformation causes the voltage side pin holder and the ground side pin holder to hold the respective plug pins 91a1 and 91a2.

Further, in the embodiment, when the plug pin 91a of the plug 9 is inserted into the pin insertion opening 51a, the holding member 2c holds the plug 9. With In a body, as shown in FIG. 8, when the plug pin 91a of the plug 9 is inserted into the pin insertion opening 51a, the holding member 2c formed in the recess member 2b of the socket cover 2 is from the lower side thereof The plug case 92 is in contact with the rear surface 92b. That is, the holding member 2c is hooked on the rear surface 92b of the plug case 92 to hold the plug 9. Since the socket cover 2 is biased by the biasing spring 34 to pivot clockwise as shown in Fig. 8, the holding member 2c pushes the plug 9 upward, so that the plug 9 can be stably held. In the case where such a configuration of the plug 9 is held by the holding member 2c, it is difficult to remove the plug 9 from the socket 1. For example, even in the case where the user's foot is caught by the cable of the plug 9, the plug 9 is difficult to detach from the socket 1.

Further, in the present embodiment, the recess member 51e is formed in the socket case 51, and the plug case 92 is inserted into the recess member 51e. Therefore, in a state where the plug pin 91a of the plug 9 is inserted into the pin insertion opening 51a to apply a current to the plug 9, no gap is generated between the front surface 92a of the plug case 92 and the insertion opening 42f. Therefore, the plug pin 91a to which the current is applied becomes difficult to be touched by, for example, a hand.

Finally, referring to Figures 7 and 8, the operation of detaching the plug pin 91a of the plug 9 from the pin insertion opening 51a will be described.

From the state in which the plug pin 91a of the plug 9 is inserted into the pin insertion opening 51a (see Fig. 8), the handle portion 2a is held by the hand to pivot the socket cover 2 rearward. Now, since the holding member 2c is away from the rear surface 92b of the plug case 92, if the plug 9 is pulled in a direction (downward) opposite to the direction in which the plug 9 is inserted, the plug pin 91a of the plug 9 becomes self-plug The insertion port 51a is detached. In this state, when pulling the plug At 9 o'clock, the plug 9 can be easily detached.

When the hand is removed from the handle portion 2a of the socket cover 2 after the plug 9 is detached, the socket cover 2 is pivoted to the closed position by the biasing force of the biasing spring 34 (clockwise in FIG. 7) ). Since the shaft 32 is fitted into the pivotal support member 21 of the socket cover 2 by being pressed in, the shaft 32 is also pivoted together with the socket cover 2. In this state, the shaft 32 and the damping member 33 rub against each other to generate sliding resistance. Therefore, the sliding resistance reduces the pivoting speed of the shaft 32 and the socket cover 2. According to the present embodiment, the pivoting speed of the socket cover 2 in contact with the decorative cover 6 can be reduced as compared with the pivoting speed of the socket cover without the damping member. Therefore, the impact caused by closing the socket cover 2 can be weakened. Further, in the present embodiment, since the damping member 33 is fixed to the support body 31 so as not to move, the shaft 32 is pivoted with the sliding resistance greater than the sliding resistance of the shaft without the damping member 33.

As mentioned above, the arrangement of the damping member 33 attenuates the impact caused by closing the socket cover 2, thereby preventing the large noise caused by closing the socket cover 2 and the damage of the socket cover 2 due to the impact. . Further, since the damping member 33 for adding the sliding resistance is formed in an integrated manner with the support member 3, neither the socket body nor the socket cover is enlarged in size, which is different from the conventional socket. Furthermore, since it is not necessary to align the damping member 33 (unlike the conventional socket), the socket 1 can be easily assembled.

(Second embodiment)

A second embodiment of the present invention will now be described with reference to FIG. Due to the second The embodiment has the same configuration as that of the first embodiment, except that the drain hole 22 and the rib 23 are provided in the socket cover 2, and detailed descriptions of components other than the socket cover 2 will be omitted.

In the first embodiment, since the socket cover 2 is provided to cover the bottom surface of the decorative cover 6, it is difficult for water to penetrate into the space surrounded by the socket cover 2 and the decorative cover 6 (the pin insertion opening 51a) Located in the space). However, even with such a configuration, it is difficult to prevent water from penetrating into the space. For example, it is feared that rainwater may infiltrate through a slight gap between the handle portion 2a of the socket cover 2 and the front wall member 6b of the decorative cover 6. For example, this water flows into the support member 3 located in the bottom of the socket cover 2, and the damping member 33 made of urethane can be degraded.

Therefore, as shown in FIG. 9, in this embodiment, the drain hole 22 is provided between the two pivot support members 21 in the socket cover 2, and the ribs 23 are provided at the front of the pivot support member 21. Middle (on the side of the handle portion 2a viewed from the pivoting support member 21). In a state where the socket cover 2 is attached to the support member 3, the drain hole 22 is formed to create a gap between the support step 31c and the socket cover 2. The rib 23 is formed on the top surface of the socket cover 2 (the surface opposite to the pin insertion opening 51a when the socket cover 2 is in the closed position) to flow from the handle portion 2a to the pivotal support member 21 The water is directed to the drain hole 22. Further, the rib 23 is formed to protrude from the top surface such that its side surface facing the handle portion 2a is inclined to form a V shape toward the drain hole 22 and the pivot support member 21. Therefore, the water penetrating into the above space flows along the rib 23 to the drain hole 22 or the pivot The outside of the support member 21 is turned and then discharged to the outside. Therefore, the degradation of the damping member 33 due to the flow of water into the pivotal support member 3 can be prevented.

(Third embodiment)

A third embodiment of the present invention will now be described with reference to FIG. Since the third embodiment has the same structure as the first embodiment, a detailed description of the components other than the socket cover 2 will be omitted except that the waterproof sealing package 24 is provided in the socket cover 2.

In this embodiment, a waterproof sealing package 24 having a substantially U-shape made of an elastic material such as an elastomer is provided on the top surface of the socket cover 2 (when the socket cover 2 is in the closed position, with the pins) The insertion port 51a is opposed to the surface thereof and its side surface. Therefore, when the socket cover 2 is in the closed position, the socket cover 2 comes into contact with the decorative cover 6 without any gap, and thus water is prevented from penetrating into the space surrounded by the socket cover 2 and the decorative cover 6.

In the present embodiment, the drain holes and the ribs may be provided in the socket cover 2 as in the second embodiment.

(Fourth embodiment)

A fourth embodiment of the present invention will now be described with reference to FIG. The upper and lower directions in the following explanation correspond to the vertical direction in FIG. Since the fourth embodiment has the same structure as the first embodiment, except that the cushioning member 100 is disposed in the lower wall member 42c below the protruding portion 42, the same reference numerals are assigned to the same members, and detailed description thereof will be omitted. .

As shown in FIG. 11, a cylindrical cushioning member 100 made of polyurethane is disposed on the bottom surface of the lower wall member 42c of the protruding section 42 to It stands out. In the case where the socket cover 2 is pivoted from the open position to the closed position, except that the pivoting speed of the socket cover 2 is lowered due to the sliding resistance generated between the damping member 33 and the shaft 32 (as in the first embodiment) In addition, the socket cover 2 is in contact with the cushioning member 100, so that the impact is further reduced. Therefore, the impact can be reduced more than in the first embodiment.

Note that the cushioning member 100 may be disposed on the exposed surface 51b of the socket case 51 or on the top surface of the socket cover 2, or may be disposed in a plurality of places.

In the present embodiment, the drain hole, the rib, and the waterproof sealed package can be provided as in the second embodiment or the third embodiment.
