Plug and socket and connecting device including the same

The present invention relates to a plug and a socket having a door body which is in an open and closed state in which an insertion port to be inserted by a plug pin is opened. The invention also relates to a connection device comprising the above plug and socket.

There is a well-known socket which is provided with a door body which can cover the insertion hole to prevent dust from being deposited on the insertion hole (for example, Japanese Patent Application Laid-Open No. Hei No. 11-365312). The socket should be opened by hand to expose the jack, and the plug can be inserted into the jack. When the plug is not connected to the outlet, the door will close to cover the jack.

With regard to the socket having such a door body, the problem is that it is difficult to align the pins with the socket because the door body and the plug interfere with each other when the plug is inserted. To solve this problem, the user can grasp the door with one hand and insert the plug into the jack with the other hand. However, in this case, the user must hold the door so that the door and the plug do not interfere with each other, which makes the operation of inserting the plug into the socket complicated.

In view of the foregoing, it is an object of the present invention to provide a plug and socket that facilitate insertion of a pin of a plug into a jack, and a connection device including the plug and the socket.

In accordance with one aspect of the present invention, a socket is provided that is adapted to be coupled to a plug from which the pin extends from the body of the plug. The socket includes: a socket unit having a plug insertion surface and a pin receiver, wherein the plug insertion surface is formed with a socket, and the pin receiving member is for clamping a pin inserted into the insertion hole; a support body extending from the socket unit, wherein the support body has a restricting part formed in a support surface facing the plug body, and when the plug is connected to the socket, the stopper member is formed with the plug The protruding parts on the main body are in contact such that the stopper member can restrict the movement of the plug main body in an orthogonal direction perpendicular to the insertion direction of the pin in a plane extending along the support surface, and guide the plug main body with respect to The socket unit is positioned such that the pins can be aligned with the socket.

In such a configuration, since the stopper member provided in the support body can come into contact with the protruding member to guide the position of the plug relative to the socket so as to be inserted into the alignment hole, the configuration of the stopper member is not provided. The position of the plug relative to the socket is easily fixed. In this way, the pin can be easily inserted into the jack.

The stopper member may be configured to be formed in a support surface of the support body and capable of accommodating a recess of the protrusion member, the groove having a slope portion extending from the bottom of the groove along the insertion direction of the pin toward the support surface Tilted.

According to this configuration, since the stopper member is formed in the groove portion, the position of the plug relative to the socket can be fixed as long as a simple structure is provided in the support body. In addition, the slope portion formed in the groove portion enables the protruding member to easily climb up and over the groove. In this way, it becomes easy to move the protruding member from the stopper member toward the surface of the support.

A fixing member may be provided on the supporting surface of the supporting body. When the pin is clamped by the pin receiving member, the fixing member can fix the protruding member, and the fixing member is closer to the socket unit than the stopping member in the insertion direction of the pin .

Along the pin insertion direction V, the direction in which the plug B is connected to the socket cover 16 is referred to as a "connection direction", and the direction in which the plug B is separated from the socket cover 16 is referred to as a "disengagement direction".

As shown in Fig. 7C, when the plug B is inserted in the connecting direction, the protruding member 94 of the plug B comes into contact with the front end of the door body 7. When the plug B continues to be inserted from this state in the connecting direction, the front slope portion 94b of the protruding member 94 causes the door body 7 to continue to pivot in the opening direction. As a result, the lower end portion 94a contacts the door body 7.

As shown in FIG. 7D, when the plug B continues to be inserted from the state in which the lower end portion 94a contacts the door body 7 toward the connecting direction, the protruding member 94 is accommodated to the stopper member 87. Specifically, the protruding member 94 is guided into the stopper member 87 by the front slope inclined surface 85a of the door body 7, and then comes into contact with the bottom portion 84 of the stopper member 87. Therefore, when the protruding member 94 is guided into the stopper member 87, the door body 7 is pivoted toward the closing direction.

Further, in this state, the pin 91 is positioned to correspond to the insertion hole 75 in the pin insertion direction V. Specifically, the tip end 91b1 of the ground pin 91b is located just to be inserted into the corresponding insertion hole 75 (the ground pin insertion hole 75b). On the other hand, the power pin 91a is located in front of the corresponding jack 75 in the pin insertion direction V. In a state in which the pins 91 are arranged in the above-described manner with respect to the insertion hole 75, when the plug B is moved in the pin insertion direction V, the pins 91 can be inserted into the respective insertion holes 75.

As shown in Fig. 8, in the state shown in Fig. 7D, the width H1 of the lower end portion 94a of the protruding member 94 in the left-right direction Y is substantially equal to the width H2 of the plane 84a of the bottom portion 84 of the groove 81 in the left-right direction Y. . Therefore, even when the protruding member 94 moves in the left-right direction Y, it is restricted by the groove 81. In other words, when the protruding member 94 is to be perpendicular to the pin insertion direction V and the opening/closing direction W (that is, the spring 10 (see FIG. 1) applies a biasing force to the door body 7 of the contact protruding member 94 when in the open position. When moving in the left-right direction Y, the stopper member 87 restricts the movement of the protruding member 94 so that the pin 91 can be kept aligned with the insertion hole 75.

As shown in FIG. 9A, when the plug B is continuously inserted into the pin insertion direction from the state in which the projection member 94 is housed in the stopper member 87, the front slope portion 94b of the projection member 94 comes into contact with the slope portion of the groove 81. 89. Then, the protruding member 94 slides on the slope portion 89 and moves to the upper surface 86c. The contact between the protruding member 94 and the slope portion 89 causes the door body 7 to move toward the opening direction. Further, the power pin 91a is inserted into the corresponding jack 75 (power pin jack 75a).

As shown in Fig. 9B, when the plug B is inserted into the socket A and the lower end portion 94a of the protruding member 94 contacts the upper surface 86c, the door body 7 is moved to the maximum open position.

As shown in FIG. 9C, after the protruding member 94 passes over the upper surface 86c, it is accommodated to the fixing member 88. At the same time, as the door body 7 pivots in the closing direction, the contact surface 96 contacts the upper surface 86c, and the holding surface 94d of the protruding member 94 contacts the partition wall 86. As a result, the connection between the plug B and the socket A is completed. Therefore, the pin 91 is held by the pin receiving member 61 (see Fig. 2A). In this state, even if an external force is applied to the plug B in the left-right direction Y, since the protruding member 94 contacts the fixing member 88, it is possible to prevent the external force from being transmitted between the pin 91 and the pin receiving member 61. Connect the part.

As described above, only the operation of the plug B can connect the plug B to the socket A when the door body 7 is rotated to the open position, while also providing a retaining mechanism to prevent the plug B from coming off the socket A. In other words, the user only needs to hold the plug B with one hand to connect the plug B to the socket A and activate the above-described brake mechanism.

Further, in this state, the rear surface 86a of the partition wall 86 and the holding surface 94d are perpendicular to the pin insertion direction V.

Even when the plug B is inadvertently subjected to an external force, for example, the cable 92 (see Fig. 6A) is hooked so that the plug B is to be detached from the socket A, since the holding surface 94d is in the pin insertion direction V with the rear surface 86a of the partition wall 86 Contact, so that the plug B can be prevented from coming off the socket A. In particular, in this state, since the rear surface 86a and the holding surface 94d of the partition wall 86 both extend in a direction substantially perpendicular to the pin insertion direction V and the retaining surface 94d and the rear surface 86a of the partition wall 86 The flat contact method is adopted, so that the force applied from the front side of the plug B in the direction in which the plug B is disengaged is carried by the partition wall 86.

Further, the outer diameter of the portion of the plug body 90 to be inserted into the groove 73 is substantially equal to the inner diameter of the groove 73. Therefore, there is only a slight gap between the plug body 90 and the groove 73. Here, "small gap" means that the user's finger is not accommodated in the gap.

As shown in FIG. 10A, when the plug B is to be detached from the socket A, the user pushes the end portion of the substrate 80 in the opening direction in the detaching direction. At this time, in the pin insertion direction V, the protruding member 94 and the partition wall 86 have no overlapping portion. In other words, the holding surface 94d does not contact the partition wall 86. At this time, the user pulls the plug B in the disengagement direction, and the plug B can be disengaged from the socket A.

Since the size of the substrate 80 in the left-right direction Y is larger than the outer diameter of the plug main body 90 (see FIG. 8), the user is compared with the case where the outer diameter of the plug main body 90 is equal to the size of the substrate 80 in the left-right direction Y. It is easier to push the door body 7.

As shown in Fig. 10B, after the plug B is disengaged from the socket A, the door body 7 is biased by the spring 7 (see Fig. 1) and pivoted to the bottom end surface 52 of the trim cover 6, i.e., to the closed position.

According to this embodiment, the following effects are expected.

(1) This embodiment is configured to form the stopper member 87 in the substrate 80 of the door body 7. According to this configuration, since the protruding member 94 of the plug main body 90 is housed in the stopper member 87, the position of the plug B in the left-right direction Y with respect to the insertion hole 75 is fixed. As a result, it becomes easier for the plug B to align the jack 75 in the left-right direction.

The waterproof socket according to the present embodiment is widely known because the opening of the jack is facing downward to prevent rainwater from penetrating into the jack. In such a waterproof socket, the user can hardly see the jack, making it difficult to connect the plug to the outlet.

Conversely, the present embodiment can fix the position of the plug B in the left-right direction Y with respect to the insertion hole 75 through the stopper member 87. Therefore, it is only necessary to move the plug B in the pin insertion direction in this state, and the plug B can be connected to the socket A.

(2) The present embodiment is configured to insert the tip end 91b1 of the ground pin 91b into the ground pin insertion hole 75b when the protruding member 94 is received to the stopper member 87. Therefore, when the protruding member 94 is accommodated to the stopper member 87, the position of the pin 91 with respect to the insertion hole 75 is fixed except that the position of the plug B with respect to the insertion hole 75 in the left-right direction Y is fixed. In this way, the user can connect the plug B to the socket A more easily and smoothly.

(3) This embodiment is configured to form the ramp portion 89 in the door body 7. In this way, it is only necessary to move the plug B from the stopper member 87 in the pin insertion direction V, and the plug B can easily climb up and pass over the partition wall 86 (the stopper member 87). Therefore, the user does not have to move the door body 7 by hand alone in the opening direction in order to pass the plug B over the partition wall 86 (the stopper member 87). In this way, the user can easily connect the plug B to the socket A.

Further, the ramp portion 89 is configured to be coupled to the front side of the partition wall 86. In this way, it is possible to prevent the partition wall 86 from being deformed and damaged forward due to the contact surface 86d of the plug B contacting the partition wall 86. That is, the ramp portion 89 also functions to reinforce the partition wall 86.

(4) This embodiment is configured such that the partition wall 86 comes into contact with the holding surface 94d when the plug B has been connected to the socket A. In this way, the plug B can be prevented from accidentally coming off the socket A.

At this time, regarding the brake mechanism for preventing the plug from coming off the socket, it is known that the pin receiving members of the pin and the terminal plate respectively have the engaging members, and the respective engaging members are coupled to each other to keep the plug connected to the socket. status. However, the elastic deformation of the pin receiving member in such a brake mechanism becomes larger than that of the pin receiving member that does not provide the brake mechanism. Therefore, there is a problem in that the rigidity of the pin receiving member tends to be deteriorated.

In contrast, in the present embodiment, since the door body 7 has the partition wall 86 and the plug main body 90 has the holding surface 94d, it is not necessary to provide the brake mechanism composed of the pin 91 and the pin receiving member 61. Therefore, in the present embodiment, even if the number of times of connection and separation between the plug B and the socket A is increased, the plug B is prevented from coming off the socket A, compared with the structure in which the brake mechanism is formed on the pin and the pin receiving member, respectively. The function is maintained.

(5) The present embodiment is configured to form the groove 81 in the substrate 80 and form the partition wall 86 and the stopper member 87 in the groove 81. According to this configuration, the amount of rotation of the door body 7 pivoting toward the opening direction when the plug B is inserted into the socket A is compared with the door body in which the partition wall 86 and the stopper member 87 protrude from the substrate 80 in the closing direction. Can be reduced. As a result, the force required to open the door body 7 can be reduced, so that the plug B can be easily inserted into the socket A.

(6) This embodiment is configured to provide the front slope bevel 85a in the joint portion 85 corresponding to the stopper member 87. According to this configuration, when the protruding member 94 is received to the stopper member 87, the front slope inclined surface 85a guides the projection member 94 to the bottom portion 84. As a result, the protruding member 94 is easily accommodated to the stopper member 87.

(7) This embodiment is configured to provide a side slope bevel 85b in the joint portion 85. According to this configuration, even if the protruding member 94 of the plug main body 90 is not aligned with the bottom portion 84 of the stopper member 87 in the left-right direction Y, the projection member 94 can be guided through the contact between the projection member 94 and the side slope inclined surface 85b. To the bottom 84. As a result, the protruding member 94 is easily accommodated to the stopper member 87.

(8) The present embodiment is configured such that the substrate 80 protrudes more from the front and side faces of the side wall portion 50. In this way, the door body 7 can be opened from the closed position by hooking the protruding portion of the door body 7 with the plug main body 90 or the user's finger.

In particular, when the plug main body 90 is used to hook the protruding portion of the substrate 80, since the continuous operation of the plug B connected to the socket A can be performed using only the plug main body 90, the user can perform the above operation with one hand.

(9) This embodiment is configured such that the bottom surface 74 of the socket cover 16 and the bottom end surface 52 of the trim cover 6 are substantially parallel to each other.

Among them, for the socket in which the jack 75 is opened downward (such as a waterproof socket), as described above, it is difficult for the user to see the jack. Therefore, it is more difficult for the user to grasp the tilt angle of the plug B with respect to the jack 75.

Conversely, in the present embodiment, the bottom end surface 52 that the user can see is configured to be substantially parallel to the bottom surface 74. Therefore, the user can easily insert the pin 91 of the plug B into the insertion hole 75 by judging the inclination angle of the plug B with respect to the bottom end surface 52.

(10) The present embodiment is configured such that the width H1 of the protruding member 94 is substantially equal to the width H2 of the plane 84a. As a result, the movement of the protruding member 94 in the left-right direction Y can be limited. Thus, the plug B is easily inserted into the socket A.

(11) The present embodiment is configured to provide the stopper member 87 on the surface 80a of the substrate 80 while defining the direction in which the door body 7 pivots downward as the "opening direction". Therefore, when the door body 7 is opened, the user can see the position of the stopper member 87. As a result, it becomes easy for the user to accommodate the protruding member 94 to the stopper member 87.

(12) The present embodiment is configured such that the rear surface 86a and the holding surface 94d of the partition wall 86 are perpendicular to the pin insertion direction V, and when the plug B is connected to the socket A, the holding surface 94d and the rear surface 86a of the partition wall 86 are Contact in a flat manner. As a result, the force applied from the front to the plug B to disengage the plug B is carried by the partition wall 86, thereby improving the braking function of the plug B with respect to the socket A.

(13) This embodiment is configured to provide a planar contact surface on the plug body 90. As a result, in the present embodiment, the connection angle between the partition wall 86 and the holding surface 94d can be increased as compared with the structure in which the portion not providing the contact surface 96 and corresponding to the contact surface of the plug body 90 is curved. .

(14) This embodiment is configured to have a spring 10 that biases the door body 7 toward the closed position. According to this configuration, the door body 7 can be automatically pivoted from the open position to the closed position. In this way, the user can be prevented from leaving the door body 7 in an open state.

(15) The present embodiment is configured to: provide a recess 73 in the socket cover 16; and provide a receptacle 75 in the bottom surface 74 of the socket cover 16. In this way, when the plug B is inserted into the socket A, the user can be prevented from connecting the pin to the pin receiving member 61 with the finger contacting the pin 91.

(16) The present embodiment is configured to provide a fine gap between the plug main body 90 and the recess 73 because the inner diameter of the recess 73 is approximately equal to the outer diameter of the portion of the plug main body 90 to be inserted into the recess 73. . In this way, the user can be prevented from inserting his or her finger into the gap between the recess 73 and the plug body 90. Therefore, the effect of preventing the user from connecting the pin 91 to the pin receiving member 61 in the case where the finger contacts the pin 91 is further enhanced.

Further, when the plug B is connected to the socket A, even if an external force is applied to the plug B (such as the cable 92 is pulled) and the plug B is biased toward the connecting direction, since the plug main body 90 contacts the recess 73, it can be prevented. The plug B is biased toward the pin insertion direction V. As a result, the pin 91 can be prevented from being bent or the insertion hole 75 can be broken.

(17) This embodiment is configured to provide a bottom surface 74 inside the opening 25 of the socket A. This prevents water from penetrating into the receptacle 75 of the bottom surface 74 as compared to a configuration in which the bottom surface 74 and the opening 25 are at the same level or the bottom surface 74 is outside the opening 25 of the socket A. Therefore, the waterproof performance of the socket A can be further improved.

(18) This embodiment is configured to provide a front slope bevel 85a in the groove 81 of the door body 7. In this way, even if water seeps into the stopper member 87, the door body 7 can be opened to allow water to be discharged downward through the front slope slope 85a. This prevents water from remaining in the stopper member 87, thereby preventing water from penetrating into the insertion hole 75 through the stopper member 87.

(19) The present embodiment is configured such that substantially the entire circumference of the substrate 80 of the door body 7 projects from the front and side surfaces of the side wall portion 50. According to this configuration, the user can hook the door body 7 from all directions with the finger or the plug main body 90, and rotate the door body 7 in the opening direction. It is more convenient to open and close the door body 7 as compared with the structure in which the door body 7 projects from the front or side of the side wall portion 50. Therefore, the operability of the socket A is improved.

(20) This embodiment is configured such that the substrate 80 is in contact with the entire periphery of the bottom end surface 52 of the trim cover 6. This prevents water from penetrating into the socket A from between the door body 7 and the trim cover 6 as compared with a structure in which the substrate 80 does not contact the bottom end surface 52 or partially contact the bottom end surface 52.

In addition, even when the door body is in the closed position, the spring 10 applies a biasing force to the substrate 80 to bias the substrate 80 toward the bottom end surface 52, so that the gap between the substrate 80 and the bottom end surface 52 is reduced. As a result, the effect of preventing water from penetrating into the socket A between the door body 7 and the trim cover 6 is further enhanced.

(21) This embodiment is configured to provide a curved depression 83 at the front end portion of the substrate 80. In this way, when the user opens the door body 7 with a finger, the door body 7 can be opened by simply hooking the curved recessed area 83 with a finger. Therefore, it becomes convenient for the user to open the door body 7 with a finger.

(22) This embodiment is configured to provide a position indicator 95 on the plug body 90. In this way, the user can arrange the pins 91 by aligning the pins 91 with the viewing position indicators 95. Therefore, it is convenient for the user to insert the plug B into the socket A.

(Second embodiment)

The second embodiment will be explained below with reference to Figs. 11 to 13B. In the present embodiment, the socket and the plug of the present invention are exemplified by a waterproof socket mounted on the outer wall of the house and a plug inserted into the waterproof socket. The door body 7 and the plug body 90 in this embodiment have various shapes. The following mainly describes the differences between the second embodiment and the first embodiment. The same component symbols represent the same components and will not be described again.

As shown in Fig. 11, a joint wall 89a is provided in the door body 7, and the slope portions 89 are joined in the left-right direction Y. This joint wall 89a forms a wall extending in the left-right direction Y and the up-and-down direction Z.

Here, the stopper member 87 is a region of the groove 81 located in front of the slope portion 89. Further, the fixing member 88 including the joint wall 89a is a region of the groove 81 behind the slope portion 89. As a result, when the protruding member 94 (see FIG. 12) comes into contact with the stopper member 87, the door body 7 restricts the movement of the protruding member 94 in the left-right direction Y. When the protruding member 94 comes into contact with the fixing member 88, the door body 7 restricts the movement of the protruding member 94 in the direction in which the pin insertion direction V is disengaged.

Further, on the right hand side of the surface 80a of the substrate 80, an indicator 80b is provided for indicating the arrangement of the pins 91 (see FIG. 12) of the plug B and the voltage of the socket A, which is formed by integral molding. (integral molding) to form.

As shown in Fig. 12, behind the projecting member 94 of the plug body 90, an engaging member 97 is provided which has a recess which is recessed upward and opens rearward. Further, the side slope portion of the protruding member 94 is formed in a curved shape that protrudes outward in the left-right direction Y.

As shown in Fig. 13A, when the plug B has been connected to the socket A, the ramp portion 89 and the engaging member 97 are coupled to each other. At this time, the holding surface 94d of the protruding member 94 of the plug B contacts the joint wall 89a in the pin insertion direction V.

As shown in Fig. 13B, the width T1 of the groove of the engaging member 97 in the left-right direction Y is substantially equal to the width T2 of the two slope portions 89 (see Fig. 11) in the left-right direction Y. The width T1 of the groove of the engaging member 97 may be slightly larger than the width T2 of the two slope portions 89. In this way, the ramp portion 89 can be smoothly engaged in the recess of the engaging member 97 of the plug.

In the present embodiment, the side surfaces of the two slope portions 89 in the left-right direction and the inner surface of the groove of the engaging member 97 in the left-right direction Y opposite to the side surface are formed along the pin insertion direction V and the opening/closing direction W. The plane of the extension. As a result, when an external force is applied to the plug B in the left-right direction Y and the plug B is attempted to move in the left-right direction Y, the inner surface of the groove of the engaging member 97 comes into surface contact with the side surface of the slope portion 89. Therefore, when the plug B is connected to the socket A, that is, when the pin 91 is held by the pin receiving member 61 (see Figs. 2A, 2B), the movement of the plug B in the left-right direction Y can be restricted.

According to the second embodiment, it is expected that the following effects should be possessed in addition to the effects (1) to (22) of the first embodiment.

(23) In the present embodiment, when the plug B is connected to the socket A, the engaging member 97 is engaged with the slope portion 89. In this way, in this state, it is possible to prevent the pin 91 of the plug B from being detached from the pin receiving member 61 of the socket A by the external force applied to the plug B in the left-right direction Y.

(24) In the present embodiment, since the engaging member 97 has a groove shape, the slope portion 89 can be accommodated on both sides in the left-right direction Y, so that the plug B is restricted from moving in the left-right direction Y with respect to the door body 7. The structure can be simplified.

(25) The present embodiment is configured such that the side slope portion 94c has a curved shape that protrudes outward in the left-right direction Y. This improves the appearance of the plug B as compared with the case where the side slope portion 94c is planar.

Further, when the plug B for outdoor use is placed on the ground such as asphalt, the curved side slope portion 94c can prevent the protruding member 94 from contacting the asphalt. As a result, the protruding member 94 of the plug B is turned over away from the asphalt. Therefore, the plug B resting on the asphalt may reduce the force that the protruding member 94 is pressed against the asphalt by the vehicle even if it is pressed by the vehicle. Therefore, the protruding member 94 can be prevented from being damaged.

(26) Since the waterproof socket is used outdoors, water (such as rain) may penetrate between the trim cover 6 and the substrate 80 of the door body 7. As indicated by the arrow in Fig. 4, water passes through the stopper member 87 of the substrate 80 due to its own weight, passes over the partition wall 86 and penetrates into the fixing member 88, and then drops from the gap between the substrate 80 and the shaft body 9. However, since the stopper member 87 is recessed and separated from the fixing member 88 by the partition wall 86, some water is left in the stopper member 87.

In view of the above problems, the present embodiment is configured to not provide the partition wall 86. As a result, as shown by the arrow in Fig. 11, the water penetrating into the gap between the decorative cover 6 and the substrate 80 passes through both sides of the slope portion 89 in the left-right direction Y, and penetrates into the fixing member 88, and then from A gap is formed between the substrate 80 and the shaft body 9. Therefore, it is possible to prevent water from remaining in the stopper member 87.

(27) In the present embodiment, the indicator 80b is formed on the surface 80a of the substrate 80. As such, when the operator connects the plug B to the outlet A, the indicator 80b can be observed while the door body 7 is in the open position. Since the operator can check whether the plug B is suitable for the supply voltage of the outlet A, it is possible to prevent the operator from connecting the plug to the outlet A which provides an inappropriate supply voltage.

Moreover, since the operator can view the arrangement of the pins 91 through the indicator 80b, the operator does not have to directly view the position of the jack 75. In this way, it is convenient to connect the plug B to the socket A.

(Third embodiment)

The third embodiment will be explained below with reference to Figs. 14 to 15 . In the present embodiment, the socket and the plug of the present invention are exemplified by a waterproof socket mounted on the outer wall of the house and a plug to be inserted into the waterproof socket. The difference between this embodiment and the first embodiment is that a shield is provided in the trim cover 6. The following is mainly to explain the difference between the present embodiment and the first embodiment. The same component symbols represent the same components and will not be described again.

As shown in Fig. 14, in the central portion of the side wall portion 50 of the decorative cover 6 in the left-right direction Y, a recess 53 in which the opening is recessed downward and rearward is provided. The shield 17 for protecting the trim cover 6 is mounted in this recess 53 in the form of a separate member. Further, when the door body is in the closed position, the shield plate 17 corresponds to the stopper member 87 in the left-right direction Y (see FIGS. 3A, 3B). In other words, when the door body is in the closed position, the position of the stopper member 87 corresponds to the position of the fender 17 in the left-right direction Y. Note that this embodiment is to form a substantially planar shield 17 by squeezing stainless steel.

Further, for the socket not having such a shield 17, when the plug B is inserted into the socket, particularly when the plug B moves the door body 7 to the open position, the plug body 90 is rotated during the opening direction of the door body 7 A part of it contacts the door body 7. In particular, when the plug B moves the door body 7 to the open position, the plug body 90 contacts the curved recessed portion 83 which is formed at approximately the same position as the stopper member 87 in the left-right direction Y. At this time, since the upper end of the plug main body 90 is inclined rearward, the pin 91 may come into contact with the center portion of the trim cover 6 corresponding to the stopper member 87 in the left-right direction Y. Since the decorative cover 6 is made of synthetic resin, when the pin 91 comes into contact with the decorative cover 6, the decorative cover 6 is scratched and damaged. Therefore, the following problem may occur: the decorative cover 6 is corroded by oxidation of scratches, and the appearance of the socket is deteriorated.

In view of the above, as shown in FIG. 15, the shield plate 17 is provided at a position corresponding to the stopper member 87 in the present embodiment. As a result, when the plug B moves the door body 7 to the open position, the pin 91 of the plug B contacts the shield plate 17. Therefore, the pin 91 can be prevented from coming into contact with the trim cover 6.

According to the present embodiment, it is expected that in addition to the utilities (1) to (22) of the first embodiment, the following effects should be possessed.

(28) This embodiment is configured to attach the shield 17 to the trim cover 6. In this way, the pin 91 can be prevented from directly contacting the trim cover 6. Therefore, the following problem can be avoided: the decorative cover 6 is corroded by the oxidation of the scratches, and the appearance of the socket is deteriorated.

(29) This embodiment is configured to use stainless steel as the shield plate 17. According to this configuration, the shield plate 17 is less likely to rust than the case where iron is used as the shield plate 17. Therefore, the socket A is suitable for outdoor use.

(Fourth embodiment)

The fourth embodiment will be explained below with reference to Figs. 16 and 17. In the present embodiment, the socket and the plug of the present invention are exemplified by a waterproof socket mounted on the outer wall of the house and a plug inserted into the waterproof socket. The difference between this embodiment and the first embodiment is that a gap is provided between the wall and the socket. The differences between the present embodiment and the first embodiment will be mainly explained below. The same component symbols represent the same components and will not be described again.

As shown in FIG. 16, the spacer 18 is attached to the package 4 behind the socket A. The waterproof package 19 is attached to the rear of the spacer 18. This waterproof package 19 also contacts the surface of the wall WL.

As shown in FIG. 17, the spacer 18 includes a frame-shaped body member 100. This body member 100 includes an opening 101 at the center of the body member 100 for the wiring of the electric wires, and a screw insertion hole 102 at the upper and lower portions of the opening 101.

Among them, for an electric wire (first electric wire) having a wire diameter of 2 mm or less, the operator can bend it to receive it into the socket A by hand. For a wire having a wire diameter of 2.6 mm or more (second wire), the operator can hardly bend it by hand to accommodate the socket A. Therefore, if the operator wants to accommodate the second wire to the socket A by hand, the operator connects the second wire to the socket A without bending the second wire. However, if the socket A is directly attached to the surface of the wall WL, it is difficult to accommodate the second electric wire to the socket A because there is no space for accommodating the second electric wire in the front-rear direction X.

In view of the above, in the present embodiment, the spacer 18 is interposed between the surface of the wall WL and the package 4 in the front-rear direction, so that a space for accommodating the second electric wire is secured in the front-rear direction X. In this way, the second wire can be accommodated in the socket A. Further, the thickness of the spacer 18 is such that the amount by which the second electric wire projects forward from the surface of the wall WL is approximately equal to the distance between the wire connecting portion of the socket block 2 (see FIG. 4) and the surface of the wall WL.

According to the present embodiment, it is expected that in addition to the utilities (1) to (22) of the first embodiment, the following effects should be possessed.

(30) This embodiment is configured to provide a spacer 18 between the surface of the wall WL and the package 4. In this way, the second wire can be accommodated in the socket A without being bent.

(31) This embodiment is configured to provide a waterproof package 19 between the surface of the wall WL and the package 4. In this way, water can be prevented from infiltrating between the partition 18 and the surface of the wall WL.

(Fifth Embodiment)

The fifth embodiment will be explained below with reference to FIG. In the present embodiment, the socket and the plug of the present invention are exemplified by a waterproof socket mounted on the outer wall of the house and a plug inserted into the waterproof socket. The difference between this embodiment and the first embodiment is that an indicator is provided in the socket. The differences between the present embodiment and the first embodiment will be mainly explained below. The same component symbols represent the same components and will not be described again.

Referring to Figure 18, an indicator 54 is provided on the socket A for indicating whether there is power supply in the outlet A. Specifically, a through hole 55 is provided in the center portion of the side wall portion 50 of the decorative cover 6 in the left-right direction Y. The through hole 55 is substantially rectangular, and its long side extends in the up and down direction Z. A cover 56 made of a transparent synthetic resin is attached to the through hole 55. Behind the cover 56, a circuit board (not shown) is attached to the decorative cover 6, on which four light-emitting diodes are arranged in the up and down direction Z. Note that this circuit board can be attached to the holding member 21 of the main body 3. Further, other light-emitting elements can also be used without being limited to the light-emitting diodes.

Wherein, when the plug is not connected to the socket A, the ON state (conductive state) and the OFF state (non-conductive state) of the power supply of the socket A are sometimes controlled by using a switch, a control panel, or the like installed in the house. ).

In this case, it is difficult to directly check whether there is power in the outlet A for the outlet that does not provide the indicator 54. Therefore, for such a socket that does not provide the indicator 54, when the plug B is connected to the socket, the user can view the socket by determining whether there is power in the device connected to the plug B (see Figs. 6A, 6B). ON state or OFF state. In this way, after the plug B is connected, the user understands that it is necessary to set the ON state of the socket through a switch, a control panel, or the like in the room. Therefore, the operability of this socket is poor.

In view of the above, in the present embodiment, since the user can use the indicator 54 to check whether there is power in the outlet A, the user can determine the ON state of the outlet A before connecting the plug B to the outlet A. Therefore, the operability of the socket A is improved.

According to the fifth embodiment, it is expected that in addition to the utilities (1) to (22) of the first embodiment, the following effects should be possessed.

(32) According to the present embodiment, the user can intuitively and directly recognize whether or not there is power in the outlet A. Therefore, the user can determine the ON state of the outlet A before the plug B is connected to the outlet A. As a result, the operability of the socket A is improved.

The present invention is not limited to the above embodiment, but the following modifications can be made. In addition, the following improvements can also be applied to the above embodiments, and various improvements can be implemented in combination with each other. Further, the above embodiments may be implemented in combination with each other.

Although the fifth embodiment is configured to provide the indicator 54 at the center portion of the trim cover 6 in the left-right direction Y, the position of the indicator 54 is not limited thereto. The indicator 54 can be configured in a position that is convenient for the user to view. Therefore, as shown in FIG. 19, the indicator 54 can be disposed at a lower portion of the body member 20 of the main body 3.

Although the third embodiment has the shield plate 17, which is a member separate from the trim cover 6, the structure of the shield plate 17 is not limited thereto. When the plug B is inserted into the socket, the portion of the trim cover 6 that will contact the pin 91 can form a portion having a higher hardness than the other portions of the trim cover 6. Therefore, scratch resistance coatings (such as UV coating) can be used as a protective material instead of the shield plate 17, which is cured by radiating ultraviolet rays to the decorative cover 6 ( Cured) and dry. Further, the above-described region of the decorative cover 6 can be molded by double-shot molding using a synthetic resin having a hardness higher than that of the other regions of the decorative cover 6.

According to the above embodiment, the insertion hole 75 of the socket cover 16 of the socket block 2 includes a power pin insertion hole 75a which is substantially rectangular and whose long side extends in the left-right direction Y, such as a so-called 200V single-phase socket. However, the insertion hole 75 of the socket cover 16 is not limited thereto. For example, as shown in FIG. 20, the insertion hole 75 may include a power pin insertion hole 75a that is substantially rectangular and whose short side extends in the left-right direction Y, such as a so-called 100V single-phase socket.

Here, since the terminal block 13 includes the first holding member 64A and the second holding member 64B, the socket A can be applied to the 100V single-phase socket and the 200V single-phase socket as long as two types of the socket cover 16 are prepared.

Although the above embodiment is configured to have the terminal block 13 including the first clamping member 64A and the second clamping member 64B, the terminal plate 13 may include only the first clamping member 64A. In this case, a single-phase 100V and single-phase 200V socket block 2 must be prepared.

In the above embodiment, the bottom surface 74 of the socket cover 16 and the bottom end surface 52 of the trim cover 6 are parallel to each other. However, the bottom surface 74 and the bottom end surface 52 may also form different angles.

In the above embodiment, the substrate 80 projects outward from the side wall portion 50 of the trim cover 6. However, the front and sides of the substrate 80 and the side wall portion 50 may also be substantially flush with each other.

In addition, a recessed region may be formed on the sidewall portion 50, the recessed region being partially recessed rearward, such that even if the front surface and the side surface of the substrate 80 and the sidewall portion 50 are substantially flush with each other, the substrate 80 corresponds to the recessed region. The portion can also function to protrude from the side wall portion 50.

In the above embodiment, the groove 81 and the joint portion 85 of the substrate 80 have slope faces 85a and 85b. However, the joint portion 85 can also extend perpendicular to the substrate 80.

In the above embodiment, the spring 10 is used as a biasing member. However, as long as the door body 7 can be biased toward the closed position, other members than the spring 10 can be used as the biasing member.

Although the above embodiment is configured to provide the stopper member 87 and the fixing member 88 in the groove 81, the structures of the stopper member 87 and the fixing member 88 are not limited thereto. For example, as shown in FIG. 21, the stopper member 87 may be formed by a pair of ribs 110 projecting upward from the substrate 80 of the door body 7, and the fixing member 88 may be located behind the stopper member 87 and with the stopper member. 87 separate grooves are formed to form. Specifically, the rib 110 may have a rectangular parallelepiped shape and its long side extends in the front-rear direction X, and the two ribs 110 are spaced apart by a distance H3 which is substantially equal to the width H1 of the protruding member 94 in the left-right direction Y. The protruding member 94 will accommodate the space formed by the surfaces of the rib 110 and the substrate 80. Further, the fixing member 88 has a fixing surface 111 corresponding to the front end surface of the groove and extending downward from the surface of the substrate 80 in the up and down direction Z. When the protruding member 94 is received to the fixing member 88, the holding surface 94d comes into contact with the fixing surface 111.

In the above embodiment, although the slope portion 89 is provided in front of the partition wall 86, the slope portion 89 may not be provided. Further, the shape of the slope portion 89 is not limited to a smooth slope, but may also form, for example, a section of stairs having a plurality of steps.

In the second embodiment, both the slope portion 89 and the joint wall 89a are configured to have a shape that protrudes upward from the groove 81, that is, the back surface of the groove 81 has only one planar shape. However, the structure of the slope portion 89 and the joint wall 89a is not limited thereto. For example, as shown in FIGS. 22A and 22B, a recessed portion 89b recessed upward from the back surface of the recess 81 may be provided, and a slope portion 89 and a joint wall 89a which protrude upward from the upper surface of the recess 81 may be provided. In this case, the slope portion 89 includes a pair of side walls 89d extending in the front-rear direction X and the up-and-down direction Z, and a slanting wall 89c connecting the two side walls 89d in the left-right direction Y. Then, the space surrounded by the side wall 89d and the inclined wall 89c forms a recessed area 89b.

Although the above embodiment is configured to provide the slope portion 89 and the partition wall 86 (the joint wall 89a in the second embodiment) in the groove 81 of the substrate 80 of the door body 7, the partition wall 86 may not be provided (the joint wall) 89a), as shown in FIG. In this case, the holding surface 94d of the protruding member 94 on the plug main body 90 is in contact with the rear end surface 89e of the slope portion 89.

Although the above embodiment is configured to provide the slope portion 89 and the partition wall 86 (the joint wall 89a in the second embodiment) in the groove 81 of the substrate 80 of the door body 7, the slope portion 89 and the partition wall 86 (joint Walls 89a) may also be omitted, as shown in FIG. Even in this case, it is expected that the utility described in the first embodiment in accordance with the provisions (1) to (3) can be achieved.

Although the above embodiment is configured to form the groove 81 in the substrate 80 of the door body 7, as shown in FIG. 25, the groove 81 may be omitted. In this case, the partition wall 86 and the ramp portion 89 are received into the recess 73 of the socket cover 16. As a result, when the door body 7 is in the closed position, the partition wall 86 and the slope portion 89 can be prevented from interfering with the socket cover 16. Therefore, it is possible to prevent the substrate 80 from coming off the decorative cover 6 due to the above-described interference.

In the above embodiment, when the protruding member 94 is received to the stopper member 87, the stopper member 87 causes the tip end 91b1 of the grounding pin 91b to be inserted into the grounding insertion hole 75b. However, the invention is not limited thereto. For example, when the protruding member 94 is received to the stopper member 87, the ground pin 91b may be located forward of the grounding insertion hole 75b in the disengaging direction.

In the above embodiment, the stopper member 87 has a groove which is recessed from the surface of the substrate 80 in the opening direction, but the shape of the stopper member 87 is not limited thereto. The stopper member 87 can protrude from the substrate 80 in the closing direction. In this case, the partition wall 86 may also protrude from the substrate 80 in the closing direction.

Although the above embodiment is configured to form the protruding member 94 in the plug body 90, the protruding member 94 may also be omitted. In this case, the stopper member 87 accommodates the lower portion of the plug body 90, and the partition wall 86 comes into contact with the back surface of the plug body 90 (that is, the end surface of the plug body 90 in the detachment direction).

In the above embodiment, the partition wall 7 is formed with a partition wall which constitutes a brake mechanism to prevent the plug B from moving in the disengaging direction, but the structure of the brake mechanism is not limited thereto. For example, the brake mechanism can be configured such that the through hole in the pin 91 engages with the protruding member on the pin receiving member 61. Further, the above brake mechanism can also be omitted.

Although the above embodiment is configured such that the stopper member 87 and the fixing member 88 are partitioned by the partition wall 86 in the groove 81, the structure of the stopper member 87 and the fixing member 88 is not limited thereto. For example, the groove 81 is divided into two parts in the front-rear direction X, and the front groove can serve as the stopper member 87, The rear groove can serve as the fixing member 88. In this case, the rear side of the stopper member 87 can provide a rear slope inclined surface which is inclined upward from the bottom surface of the groove 81 from the front to the rear. In this way, as long as the plug B is pushed in the pin insertion direction V, the protruding member 94 can climb up from the stopper member 87 and pass over the slope of the rear slope.

In the above embodiment, the socket A is suitable for a waterproof socket for outdoor use, but the socket A is also applicable to an indoor socket.

(Sixth embodiment)

The sixth embodiment will be explained below with reference to Figs. 26 and 27. In the present embodiment, the socket and the plug of the present invention are exemplified by a waterproof socket mounted on the outer wall of the house and a plug inserted into the waterproof socket. The difference between this embodiment and the above embodiment is that the socket unit 1A is mounted with a support body for supporting the plug body 90 so that the plug body 90 does not pivot, and no pivoting is provided. Door body 7. The differences between the present embodiment and the above embodiments will be mainly explained below. The same component symbols represent the same components and will not be described again.

Further, as shown in FIG. 26, the support body 507 is fixed to one end of the substrate 580 of the socket unit 1A, and the support body 507 extends from the socket unit 1A such that the surface 581 of the substrate 580 is along the groove 73 perpendicular to the socket cover. The bottom surface 74 extends in the direction of the bottom surface 74.

The support body 507 is substantially planar as seen from above, and on the surface 581 of the substrate 580 of the support body 507, a pair of protrusions 510 are arranged apart from each other in the left-right direction.

The protrusion 510 has a triangular shape from a lateral direction and protrudes from the surface 581 of the substrate 580 of the support 507. The protrusion 510 has a slope portion The minute 511 is inclined such that the amount of protrusion increases along the insertion direction (joining direction) of the pin; and the contact member 512 extends in a direction perpendicular to the surface 581 of the substrate 580.

In the present embodiment, when the protruding member 94 of the plug main body 90 comes into contact with the projection 510, the support body 507 is bent downward with a joint position CP as a fulcrum point. As a result, the protrusions 510 are moved away from the protruding member 94. Therefore, the protruding member 94 can climb up and over the protrusion 510 and facilitate the operation of inserting the plug B into the socket A.

Further, in a state where the plug B is connected to the socket A, when the user presses down the support body 507 by hand, the support body 507 is bent downward with the connection position CP as a fulcrum. As a result, the protrusions 510 on the support body 507 are moved toward the direction away from the protruding member 94 of the plug B, so that the protrusion 510 and the protruding member 94 do not interfere with each other when the plug B is separated from the socket A. Therefore, it is not necessary to provide a special mechanism for supporting the protrusion 510 to move away from the protruding member 94 on the support body 507, thereby simplifying the support body 507.

Among them, as another alternative, the support body 607 shown in FIG. 28 can replace the support body 507. The structure of the support body 607 is similar to that of the door body 7 shown in FIG. The stopper member 687 includes a pair of ribs 610 that protrude upward from the base plate 680 of the support body 607. The fixing member 688 includes a recess formed at the rear of the stopper member 687 and separated from the stopper member 687. Specifically, the rib 610 has a rectangular parallelepiped shape with a long side extending along the insertion direction of the pin. In addition, the two ribs 610 are in the left-right direction Y. They are arranged at a distance H3 from each other, and the distance H3 is substantially equal to the width H1 of the protruding member 94 in the left-right direction Y. The protruding member 94 will be received into the space formed by the surfaces of the rib 610 and the substrate 680. Further, the fixing member 688 has a fixing surface 611 which corresponds to the front end surface of the groove and extends downward from the surface of the substrate 680 in the up and down direction Z. When the protruding member 94 is received to the fixing member 688, the holding surface 94d contacts the fixing surface 611.

(Seventh embodiment)

In the above embodiment, the socket and the plug are exemplified by a waterproof socket mounted on the outer wall of the house and a plug inserted into the waterproof socket. However, the present invention is also applicable to a plug and a socket provided in a battery charging stand for an electric locomotive. In the present embodiment, a socket provided in a battery charging stand for an electric locomotive will be described with reference to FIGS. 29A, 29B, 29C and 30.

For example, FIG. 29A, FIG. 29B, and FIG. 29C illustrate a battery charging stand (charging device) to which a socket is mounted. The battery charging stand 1011 shown in Figs. 29A, 29B, and 29C is for charging a battery in an electric locomotive. For example, the battery charging stand 1011 is installed upright outdoors. The battery charging stand 1011 has a holder main body 1012 in a rectangular parallelepiped shape, and a door 1013, for example, in a horizontally open type, which is disposed at a predetermined height in the holder main body 1012. The door 1013 is approximately quadrangular and its purpose is to close the closed state shown in Fig. 29A and open to the open state shown in Fig. 29B. As shown in FIG. 29B, the stent body 1012 has a recess 1015 at a portion corresponding to the door 1013. Then, as shown in Figure 29B As shown in Fig. 29C, the socket A is attached to the inner portion (the mounting surface) of the groove 1015 to approximate the center portion. As shown in Fig. 29C, in the socket A of the present embodiment, a plurality of jacks 1052 are provided on the front surface of the socket unit 1020 of the socket A, and the pins 91 of the plug B (see Figs. 6A, 6B) are respectively inserted into These jacks are in 1052. In the front surface of the socket unit 1020, the door body 1080 in the closed state covers a rectangular area including the insertion hole 1052.

In Figure 29C, from the front, the door body 1080 is substantially rectangular and is configured to open or close with its lower end pivoted. Since the other structure of the door body 1080 is the same as that of the door body 7 in the above embodiment, detailed description will not be given. When the door body 1080 is manipulated and changed from the closed state shown in FIG. 29C to the open state in which the jack 1052 is exposed, the user can insert the pin 91 of the plug B into the respective jack 1052. In this way, the battery of the electric locomotive can be charged by the battery charging stand 1011. In the socket A of the present embodiment, the plug B can be directly inserted, and the plug B can be locked in the braking state by the connection with the door body 1080. In this state, the plug B can be prevented from coming off the socket A.

As shown in FIG. 30, the socket A has a socket unit 1020 in which the socket 1052 is formed, and a trim cover unit 1030 attached to the front of the socket unit 1020. The trim cover unit 1030 includes a trim cover 1060 having a rectangular shape like a box, the rear of which is open, and a door opening/closing mechanism 1070. The door opening/closing mechanism 1070 includes a door body 1080 having a rectangular shape that can be opened and closed with respect to the insertion hole 1052, a shaft 1071, and a spring 1075 serving as a biasing member. Then, install the door body 1080 to open through the door The closing mechanism 1070 opens or closes the door body 1080 relative to the trim cover 1060. Since the structure of the door opening/closing mechanism 1070 is substantially the same as that of the door opening/closing mechanism 1B described in the above embodiment, detailed description will not be given. Now, a socket unit of a surface socket (not shown) is used as the socket unit 1020, so that a common component can be used between the surface socket and the socket unit 1020. Therefore, the trim cover unit 1030 can be replaced with a decorative cover of the surface socket. The function of the door body 1080 can be connected with the plug body 90 of the plug B (the pin 91 is inserted into each of the jacks 1052) in addition to opening and closing the respective jacks 1052, so that the plug B is opposite to the socket. A is locked in the braking state.

As an example of the container body, the socket unit 1020 has a housing 1021 that is approximately rectangular parallelepiped. The outer casing 1021 includes a main body 1040 in a planar square box shape, the front side of which is open, and has a rectangular shape from the front-rear direction X, the main body is formed by injection molding using synthetic resin, and the main body of the flat square box shape. The cover 1050 has a rear side open to face the open side of the main body, wherein the main body and the main body cover are connected by a plurality of mounting screws (not shown). Four mounting screws 1022 are inserted into the four corners of the front side of the socket unit 1020 and penetrated to the back side, and the mounting screws 1022 are tightened, and the socket unit 1020 is fixed to the mounting surface.

In the outlet unit 1020, a socket structure (not shown) for inserting and connecting an external electric wire is provided, which serves as a connection structure for supplying electric power on the external electric wire to the plug B. At the upper end of the socket unit 1020, a wire jack 1024 is provided through which the external wires are inserted.

As shown in FIG. 30, on the front surface 1050a of the main body cover 1050 (the front surface of the outer casing 1021), a boss 1051 which is integral with the main body cover 1050 is formed, and the convex seat has a rectangular plate shape along The front-rear direction X protrudes from the main body cover 1050 by a predetermined thickness. Three jacks 1052 are formed on the front surface of the boss 1051, and a plug B to which the ground terminal is attached will be connected to the three jacks 1052.

The decorative cover 1060 has a square box shape with its back surface open in the front-rear direction X. In the plan view of the front-rear direction X, the trim cover 1060 is identical in shape and size to the main body 1040 of the receptacle unit 1020. The trim cover 1060 is attached to the socket unit 1020 by fitting or locking to cover the front surface of the socket unit 1020. At a portion of the front surface 1060a of the trim cover 1060 corresponding to the boss 1051, a plug insertion hole 1061 is formed which is formed through the trim cover 1060 and which is circular in plan view in the front-rear direction X. A portion of the plug main body 90 of the plug B on the pin side is inserted into this plug insertion hole 1061. When the trim cover 1060 is mounted to the socket unit 1020, the three jacks 1052 are exposed through the plug insertion holes 1061.

Below the plug insertion hole 1061 on the front surface 1060a of the trim cover 1060, a semi-cylindrical shaft holding member 1062 integral with the trim cover 1060 is formed, which extends a predetermined width in the left-right direction Y. The shaft holding member 1062 constitutes a part of the door opening/closing mechanism 1070. The shaft holding member 1062 is formed to protrude from the front surface 1060a of the trim cover 1060.

In the present embodiment, the door body 1080 is pivotally mounted. However, the door body 1080 may not be used, but the support bodies 507 and 607 described in the seventh embodiment may be mounted so as not to be pivoted.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention.
