Description

  The present invention relates to a power socket power supply that is inserted into a power socket of an automobile (passenger car, motorcycle, large truck, etc.) and supplies electric power from an automobile or motorcycle to an electronic product or the like.

  2. Description of the Related Art Conventionally, there is known a power socket power feeder that can be inserted into a power socket to supply electric power from an automobile to an electronic product or the like (see Patent Document 1). As shown in FIG. 12, the power supply unit for a power socket includes an insertion portion 501 that is inserted into a power socket of an automobile at the time of use, and the power supply in a state where the insertion portion 501 is connected to the insertion portion 501 and the insertion portion 501 is inserted into the power supply socket. And a protrusion 502 that protrudes outward (opposite to the insertion direction) from the opening of the socket.

  In the power socket power supply 500, an electronic device such as a smartphone is connected by inserting a terminal such as UBS into the protruding portion 502 in a state where the insertion portion 501 is inserted into the power socket, and thus, power from the automobile is connected. Is supplied to the electronic device or the like.

  In this power supply unit for power socket 500, when pulling out from the power socket, it is possible to grip a portion (protruding portion 502) that protrudes greatly from the opening of the power socket, so that it is easy to grip and pull the portion. Can be pulled out.

Utility Model Registration No. 3153403

  In the state where the power socket power supply 500 is inserted into the power socket, the protruding portion 502 protrudes greatly from the opening of the power socket. Therefore, when operating the devices around the panel provided with the power socket, The protrusion 502 may get in the way.

  Therefore, for example, the power socket 500 power supply 500 is configured such that the protruding portion 502 is eliminated and a part of the power socket 505 does not protrude outward from the opening of the power socket 505 when the power socket 505 is inserted. A configuration in which the power feeder 500A is accommodated (see FIG. 13) or a configuration that protrudes only slightly (that is, a configuration in which the power socket power feeder 500B is substantially accommodated in the power socket 505: see FIG. 14) can be considered.

  However, in the power socket power supply devices 500A and 500B configured to be housed or substantially housed in the power socket 505, there is no portion that can be firmly gripped when being pulled out from the power socket 505, and thus it is difficult to pull out from the power socket 505.

  Then, this invention makes it a subject to provide the electric power feeder for power sockets which is easy to pull out from the state accommodated in the power socket or substantially accommodated.

  The power supply for a power socket according to the present invention can be stored or substantially stored in the power socket by being inserted into the power socket, and has a facing surface in which a terminal insertion hole is formed at the rear end in the insertion direction to the power socket. And a forward / backward member extending along the insertion / extraction direction of the power supply main body with respect to the power socket and capable of moving forward / backward from the opposing surface along the insertion / extraction direction.

  According to such a configuration, the advancing / retreating member can be provided even if there is no or almost no part (part of the power supply body) that protrudes outward from the opening of the power supply socket because the power supply body is stored or substantially stored in the power supply socket. By advancing (withdrawing) the facing surface, a portion that can be gripped outside the power socket is sufficiently secured. Thereby, the power supply socket power supply can be easily pulled out from the power supply socket by gripping (holding) the advancing / retreating member and pulling the power supply body.

  In the power socket power supply, the facing surface has a fitting portion into which a leading end in the advancing direction of the advancing and retracting member is fitted at a position where the advancing and retracting member is most retracted, and the distal end is a peripheral portion thereof In addition, an insertion hole side end portion that faces the terminal insertion hole in a state where the tip end portion is fitted in the fitting portion may be included.

  When pulling out (advancing) the advancing / retreating member with respect to the facing surface in order to pull out the power supply for the power socket from the power socket, the advancing / retreating member is operated from the facing surface side. Since the tip part fitted into the fitting part of the surface includes the insertion hole side end part facing the terminal insertion hole at the peripheral part, the peripheral part (insertion hole side) of the tip part from the terminal insertion hole side It is easy to put a finger on the end portion, and thus the advancing and retracting member can be easily pulled out (or advanced) even if the tip portion is fitted in the fitting portion.

  In the power socket power supply, the facing surface has a fitting portion into which a forward end portion of the advancing and retracting member is fitted at a position where the advancing and retracting member is most retracted. The peripheral edge portion may include an outer end portion that faces the outer surface of the opposing surface from the peripheral edge side of the opposing surface in a state in which the distal end portion is fitted in the fitting portion.

  When pulling out the advancing / retreating member with respect to the opposing surface in order to pull out the power supply unit for the power socket from the power socket, the advancing / retreating member is operated from the opposing surface side. Since the tip part fitted in the part includes the outer end part facing the outside of the opposing surface from the peripheral side of the opposing surface at the peripheral part, the peripheral part of the tip part from the outer side of the opposing surface ( It is easy to put a finger on the outer end portion, and this makes it easy for the advance / retreat member to be pulled out (or advanced) even if the tip portion is fitted into the fitting portion.

  In the power socket power supply, the opposing surface has a fitting portion into which a forward end portion of the advancing and retracting member is fitted at a position where the advancing and retracting member is most retracted, The protrusion has a protrusion that protrudes in the advancing direction from a region adjacent to the tip on the facing surface when the front end is fitted into the fitting part. In the state where it is fitted in the joint, it may be located at the same position as the portion located on the most distal side of the facing surface in the advance direction or on the backward direction side of the advance / retreat member.

  In such a configuration, the tip of the tip from the facing surface in a state in which the tip is fitted into the fitting portion is located by positioning the protruding portion of the tip in the same or backward direction side as the most tip portion of the facing surface. A place where the protrusion to the advance direction side is suppressed and the size in the insertion / extraction direction of the power supply unit for the power socket is suppressed, and the tip portion is easily hooked with a finger (a portion protruding to the advance direction side from the region adjacent to the tip portion on the opposite surface ) Is provided, and the ease of pulling out the advancing / retreating member from the state in which the tip portion is fitted in the fitting portion is also ensured.

  As described above, according to the present invention, it is possible to provide a power socket power supply that can be easily pulled out from a state where the power socket is stored or substantially stored.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

  The power supply for a power socket according to the present embodiment (hereinafter simply referred to as “power supply”) is a power supply called a so-called cigar socket or accessory socket provided in a panel of a vehicle compartment, a motorcycle, or the like. Electric power from an automobile or a motorcycle is supplied to an electronic device or the like that is inserted into (inserted into) a socket and connected to the power feeder. Among these power feeders, there are those that only supply electricity from automobiles and motorcycles to electronic devices connected to the power feeder, and those that are used for charging electronic devices and the like. Specifically, as shown in FIGS. 1 to 5, the power feeder includes a power feeder body 2 that is housed or substantially housed in a power socket, and an advance / retreat member 3 that moves forward and backward (advances and retracts) from the power feeder body 2. . In the present embodiment, “the feeder main body 2 is housed in the power socket 6” means that the feeder main body 2 protrudes outward from the opening of the power socket 6 in the insertion / extraction direction of the feeder main body 2 with respect to the power socket 6. The state where there is no power supply (see, for example, FIG. 6), “the power feeder main body 2 is substantially housed in the power socket 6” means that the power feeder main body 2 protrudes outward from the opening of the power socket 6 in the insertion / extraction direction. A state in which the power supply main body 2 is pulled out to the extent that it cannot be gripped even when it is gripped to pull out the power feeder main body 2 from the power socket 6 (see, for example, FIG. 7).

  The power feeder body 2 includes a case 21 having an internal space S, a board 22 disposed in the case 21, a connector 23 attached to the board 22, and a bottom 61 of the power socket 6 protruding from the case 21 (see FIG. 6). ) And a pair of second contacts that protrude from the opposing position of the case 21 and can contact the inner peripheral surface 62 of the power socket 6 (see FIG. 6). A second contact portion 25 having a child 251. In the following, the central axis C direction of the power feeder 1 (insertion / removal direction with respect to the power socket 6) is the X-axis direction, the direction in which the pair of second contactors 251 are arranged is the Y-axis direction, and the X-axis direction and the Y-axis direction are The direction orthogonal to the Z axis direction. Also, the right side in FIG. 4 (insertion direction of the power feeder main body 2 to the power socket 6) is one side in the X-axis direction, and the left side in FIG. 4 (direction of pulling out (pulling out) the power feeder main body 2 from the power socket 6). The upper side in FIG. 4 is referred to as one side in the Z-axis direction, and the lower side in FIG. 4 is referred to as the other side in the Z-axis direction.

  Case 21 is resinous. The case 21 includes a case main body 211 that is open on the other side in the X-axis direction, and a closing portion 215 that defines the internal space S of the case 21 in cooperation with the case main body 211 by closing the opening of the case main body 211. . The case 21 also has a partition plate 216 that partitions the internal space S of the case 21. The case 21 of the present embodiment has a columnar shape extending in the X-axis direction, and one end portion in the X-axis direction is hemispherical. The size of the case 21 in the YZ plane (the plane including the Y axis and the Z axis) at each position in the X axis direction is smaller than the inner diameter of the inner peripheral surface 62 of the power socket 6. The X-axis dimension of the case 21 is such that when the power feeder 1 (power feeder body 2) is inserted into the power socket 6, the other end in the X-axis direction protrudes outward from the opening of the power socket 6. (See FIG. 6) or the other end in the X-axis direction is set so as to slightly protrude outward from the opening of the power socket 6 (see FIG. 7). Note that the term “slightly protrudes” refers to a protruding amount that cannot be firmly gripped even if the power feeder main body 2 is pulled out of the power socket 6 to be gripped.

  The case main body 211 includes a cylindrical first portion 212 surrounding the central axis C and a hemispherical second portion 213 that closes an opening on one side of the first portion 212.

  The first part 212 has a pair of through-holes 212a penetrating in the Y-axis direction at positions facing in the circumferential direction (positions facing in the Y-axis direction in the example of the present embodiment). Each of the pair of through holes 212a has a rectangular shape that is long in the X-axis direction.

  The second portion 213 has a hemispherical shape that bulges toward one side in the X-axis direction. The second portion 213 has a through hole 213a penetrating in the X-axis direction at a position intersecting with the central axis C.

  The blocking portion 215 has a plate shape extending in the YZ plane direction, and has a facing surface 215A on which the terminal insertion hole 217 is formed on the other side in the X-axis direction. The opposing surface 215A is located at the rear end (the other end in the X-axis direction) in the insertion direction of the power supply socket 6 in the power supply main body 2, and the power supply main body 2 is inserted (stored or stored) in the power supply socket 6. It is a surface that can be seen from the opening of the power socket 6 (facing the driver or the like) in a state of being substantially stored.

  Specifically, the closing portion 215 is a fitting in which a part of the advancing / retracting member 3 is fitted to a terminal insertion hole 217 into which a terminal (USB terminal in the example of the present embodiment) can be inserted by penetrating in the X-axis direction. Part 218. The closing part 215 of the present embodiment is a disk shape extending in the YZ plane direction.

  The facing surface 215A is recessed toward one side in the X-axis direction. In the facing surface 215A of the present embodiment, the center side is recessed from the peripheral edge. Specifically, the facing surface 215A is recessed in a spherical shape toward one side in the X-axis direction. That is, the facing surface 215A is recessed so that the cross-sectional shape along the surface including the central axis C is an arc.

  The partition plate 216 extends in the XY plane (a plane including the X axis and the Y axis), and partitions the internal space S of the case 21 into one side and the other side in the Z axis direction. The partition plate 216 of the present embodiment is bent at the other end in the X-axis direction. Specifically, the partition plate 216 extends from the edge of the other side of the case body 211 in the X axis direction to the other side in the Z axis direction and extends in the YZ plane direction. And a bent portion 2162 that spreads out (see FIGS. 4 and 5). The bent portion 2162 overlaps with a part of the fitting portion 218 when viewed from the X-axis direction.

  In the case 21, the advance / retreat member 3 is disposed on one side of the partition plate 216 in the Z-axis direction, and the substrate 22, the connector 23, and the second contact portion 25 are disposed on the other side of the Z-axis direction. The partition plate 216 of the present embodiment cooperates with the case main body 211 (specifically, the portion facing the partition plate 216 of the case main body 211 in the Z-axis direction) to advance and retract the reciprocating member 3 (reciprocating in the X-axis direction). (Guidance). Further, since the partition plate 216 partitions the advance / retreat member 3 and the substrate 22, the contact of the advance / retreat member 3 and the substrate 22 when the advance / retreat member 3 advances / retreats is prevented. The substrate 22 is prevented from being damaged or short-circuited due to the above.

  The terminal insertion hole 217 has a rectangular shape that is long in the Y-axis direction, and is provided at the center of the blocking portion 215 (opposing surface 215A) (see FIG. 3).

  In the fitting portion 218, the distal end portion 31 in the advancing direction (the other side in the X-axis direction) of the advancing / retreating member 3 is fitted at the position (retreating position) where the advancing / retreating member 3 is most retracted with respect to the facing surface 215A (see FIG. 2) having a shape. The fitting portion 218 of the present embodiment is a notch extending from the terminal insertion hole 217 to one side in the Z-axis direction (the upper side in FIG. 3), and communicates with the outside on one side in the Z-axis direction and also in the Z-axis direction. It communicates with the terminal insertion hole 217 on the other side. In the fitting part (notch) 218 of the present embodiment, the interval in the Y-axis direction is the same at each position in the Z-axis direction.

  The substrate 22 includes a capacitor and the like, and is externally connected through a connector 23 connected to the substrate by transforming electricity (electricity from an automobile or a motorcycle) input through the first contact portion 24 and the second contact portion 25. Output to.

  The connector 23 is attached to the substrate 22 so as to overlap with the terminal insertion hole 217 of the closing portion 215 when viewed from the X-axis direction. The connector 23 of this embodiment is a USB connector (female connector), and a USB terminal is connected (inserted) through the terminal insertion hole 217 of the closing portion 215.

  The first contact portion 24 includes a first contact 241 that contacts the bottom 61 (see FIG. 6) of the power socket 6 when the power feeder 1 (power feeder body 2) is inserted into the power socket 6. And a biasing member 242 that biases the contact 241 toward one side in the X-axis direction. The first contact portion 24 of this embodiment has conductivity and is electrically connected to the substrate 22.

  The first contactor 241 is disposed in a state in which a portion on one side in the X-axis direction is projected from the through hole 213a of the case main body 211 (second portion 213) in the X-axis direction. The first contact 241 can reciprocate in the X-axis direction.

  The urging member 242 is, for example, a helical spring that is arranged in a posture in which the central axis thereof coincides with the central axis C of the power feeder 1.

  The second contact portion 25 includes a pair of second contacts 251 that press and contact the inner peripheral surface 62 (see FIG. 6) of the power socket 6 when the power feeder 1 is inserted into the power socket 6. And a connection portion 252 for connecting the child 251. In the second contact part 25 of this embodiment, a pair of second contactors 251 and a connection part 252 are integrally formed. The second contact portion 25 has conductivity and is electrically connected to the substrate 22.

  Each of the pair of second contactors 251 has a band shape and is curved so as to bulge outward in the Y-axis direction (a direction away from the case main body 211). Each of the pair of second contactors 251 is in a state where a portion (central portion) excluding both ends in the longitudinal direction is bulged (projected) in the Y-axis direction from the through hole 212a of the first portion 212. Has been placed. Each of the pair of second contacts 251 is configured such that the case body 211 side (center axis C side) is formed by the inner peripheral surface 62 of the power supply socket 6 by inserting the power supply body 2 (power supply 1) into the power supply socket 6. Is pressed and elastically deformed, and the inner peripheral surface 62 of the power supply socket 6 is pressed outward in the Y-axis direction by an elastic restoring force (force to return to the original shape) generated by the elastic deformation. As a result, a sufficient frictional force is generated between the pair of second contactors 251 and the inner peripheral surface 62 of the power socket 6, and the power feeder main body 2 (power feeder 1) is easily detached from the power socket 6. Is prevented.

  The connection part 252 connects the ends on the other side in the X-axis direction of the pair of second contactors 251. The connection portion 252 of the present embodiment extends so as to avoid the connector 23 and connects the pair of second contactors 251 to each other.

  The advancing / retreating member 3 advances / retreats in the X-axis direction (reciprocating motion) between an advanced position (see FIG. 8) that has advanced most from the power feeder body 2 (opposing surface 215A) and a retracted position that has retracted most (see FIG. 2). It is possible. Specifically, the advancing / retreating member 3 advances / retreats from the facing surface 215 </ b> A along the insertion / extraction direction of the power feeder body 2 to / from the power socket 6. More specifically, the advancing / retreating member 3 advances along the direction in which the feeder main body 2 is removed from the power socket 6 with respect to the facing surface 215A (state from FIG. 2 to FIG. 8). Further, the advancing / retreating member 3 moves backward along the insertion direction of the power feeder main body 2 into the power socket 6 with respect to the facing surface 215A (state from FIG. 8 to FIG. 2). The advance / retreat member 3 of this embodiment advances / retreats from the facing surface 215A by sliding in the X-axis direction. The advancing / retracting member 3 includes a distal end portion 31 that fits into the fitting portion 218 of the closing portion 215 in the retracted position, a shaft portion 32 that extends from the distal end portion 31 to the other side in the X axis direction, and the X axis direction of the shaft portion 32. And a retaining portion 33 connected to the other end portion.

  The tip portion 31 has a shape corresponding to the fitting portion (notch) 218 when viewed from the X-axis direction. The tip portion 31 of the present embodiment has a rectangular shape that is long in the Z-axis direction when viewed from the X-axis direction.

  Specifically, an end portion on the one side in the Z-axis direction of the distal end portion 31 (an outer end portion included in the peripheral portion of the distal end portion 31) 31A is connected to the closed portion 215 from the peripheral side of the closed portion 215 (opposing surface 215A). Facing outside (exposed). An end surface (outer end surface) 311 on one side in the Z-axis direction of the distal end portion 31 has an arc shape along the case body 211 (cylindrical first portion 212) when viewed from the X-axis direction (see FIG. 3). ).

  Further, the other end portion (the insertion hole side end portion included in the peripheral portion of the distal end portion 31) 31B in the Z-axis direction of the distal end portion 31 faces (is exposed) the terminal insertion hole 217. The other end surface (terminal insertion hole side end surface) 312 in the Z-axis direction of the distal end portion 31 is linear along the terminal insertion hole 217 when viewed from the X-axis direction (see FIG. 3). That is, the terminal insertion hole 217 is defined by being surrounded by the inner peripheral surface 217A (see FIGS. 2 and 3) of the blocking portion 215 and the terminal insertion hole side end surface 312 of the tip portion 31. The terminal insertion hole side end surface 312 of the present embodiment has a stepped portion 312a at one end portion in the X-axis direction (see FIGS. 4 and 5). The step portion 312a extends over the entire area of the tip end portion 31 in the Y-axis direction.

  As described above, both sides (one side and the other side) of the distal end portion 31 in the Z-axis direction are in a state of being released without being covered by the closing portion 215.

  The distal end surface (the end surface on the other side in the X-axis direction) 313 of the distal end portion 31 spreads in a direction orthogonal to the central axis C (that is, the YZ plane direction). In a state in which the distal end portion 31 is fitted in the fitting portion 218, the distal end surface 313 extends in the YZ plane direction at the same position as the peripheral edge of the facing surface 215A in the X-axis direction. That is, the distal end surface 313 of the distal end portion 31 is at the same position as the portion located on the most other side of the opposing surface 215A in the X-axis direction. In addition, although the character is carved in the front end surface 313 of this embodiment, the structure in which the character is not carved may be sufficient.

  Further, the tip portion 31 protrudes to the other side (advancing direction) in the X-axis direction from a region adjacent to the tip portion 31 in the facing surface 215A when the tip portion 31 is fitted into the fitting portion 218. It has a portion 315 (see FIG. 2). Details are as follows.

  At least a part of the region adjacent to the tip 31 on the facing surface 215A when the tip 31 is fitted into the fitting portion 218 (the region adjacent to the Y-axis direction in the present embodiment) is the tip of the tip 31. It is located on one side in the X-axis direction from the surface 313. Here, the facing surface 215A of the present embodiment is recessed in a spherical shape so as to be positioned on one side in the X-axis direction from the peripheral edge toward the center. For this reason, the region adjacent to the tip portion 31 in the facing surface 215A is separated from the tip surface 313 of the tip portion 31 toward one side in the X-axis direction from the periphery of the facing surface 215A toward the center (center axis C) side. . Thereby, in the protrusion part 315, the protrusion amount of the front-end | tip part 31 from the area | region adjacent to the front-end | tip part 31 in the opposing surface 215A increases as it goes to the center (center axis C) side from the periphery of the opposing surface 215A. The other end surface (tip surface 313) in the Z-axis direction of the projecting portion 315 of the present embodiment is the farthest other side of the opposing surface 215A in the X-axis direction in a state where the tip portion 31 is fitted in the fitting portion 218 ( It is the same position as the part (the peripheral part in the example of this embodiment) located in the most distal side in the advance direction of the advance / retreat member 3.

  Further, the width (dimension) of the tip 31 in the Y-axis direction is slightly larger than the width (interval) of the fitting portion (notch) 218 in the Y-axis direction. For this reason, when the advancing / retracting member 3 is retracted from the advanced position to the retracted position, the distal end portion 31 is pushed into (pressed into) the fitting portion (notch) 218, thereby the fitting portion (notch) 218. Fit into.

  The shaft portion 32 is a strip-shaped portion having the thickness direction in the Z-axis direction. The dimension (width) of the shaft part 32 in the Y-axis direction is the same as or slightly smaller than the dimension of the fitting part (notch) 218 in the Y-axis direction.

  The retaining portion 33 is a portion that prevents the advance / retreat member 3 from falling out of the feeder main body 2 when a force is further applied to the advance / retreat member 3 from the advanced position to one side in the X-axis direction. In the retaining portion 33 of the present embodiment, the dimension in the Y-axis direction is larger than the dimension in the Y-axis direction of the fitting portion (notch) 218, thereby preventing the above-described dropout.

  According to the power feeder 1 described above, the power feeder main body 2 is housed or substantially housed in the power socket 6 so that there is no or almost no part (part of the power feeder main body 2) that protrudes outward from the opening of the power socket 6. Even if not (see FIG. 6 and FIG. 7), a portion that can be gripped outside the opening of the power socket 6 is sufficiently secured by advancing (withdrawing) the advance / retreat member 3. Thereby, the power feeder main body 2 (power feeder 1) can be easily pulled out from the power socket 6 by gripping (holding) the advancing / retreating member 3 and pulling the power feeder main body 2.

  In the power feeder 1 of the present embodiment, the end portion 31 faces the terminal insertion hole 217 in the state where the tip end portion 31 is fitted to the peripheral portion and the fitting portion 218 (in the example of the present embodiment). The other end portion (terminal insertion hole side end portion) 31B in the Z-axis direction is included. That is, the other end 31B (terminal insertion hole side end surface 312) in the Z-axis direction of the distal end portion 31 extends from the inner peripheral surface 217A (see FIG. 3) of the closing portion 215 that defines the terminal insertion hole 217 to the terminal insertion hole. It is exposed on the 217 side.

  Here, when the advance / retreat member 3 is pulled out (advanced) to the facing surface 215A in order to pull out the power feeder 1 from the power socket 6, the advance / retreat member 3 is operated from the facing surface 215A side. According to the power feeder 1 of the embodiment, the distal end portion 31 fitted into the fitting portion 218 includes the end portion 31B on the other side in the Z-axis direction facing the terminal insertion hole 217 at the peripheral edge portion. Therefore, it is easy to put a finger on the peripheral edge portion (end portion 31B on the other side in the Z-axis direction) of the distal end portion 31 from the terminal insertion hole 217 side, so that even if the distal end portion 31 is fitted in the fitting portion 218, it advances and retreats. The member 3 is easy to pull out (advance).

  Moreover, as shown in FIG. 9, when the case main body 211 is adjacent to one side of the tip end portion 31 in the Z-axis direction, the end portion 31B of the tip end portion 31 on the other side in the Z-axis direction is pulled with a finger. Since the tip 31 is pressed against the case body 211 (see arrow α in FIG. 9), it is difficult to pull out, but one side in the Z-axis direction of the tip 31 is released like the power feeder 1 of the present embodiment. As a result (see FIG. 4), the front end portion 31 is not pressed against the case main body 211 and the like, and the advance / retreat member 3 is easily pulled out.

  In the power feeder 1 of the above embodiment, the distal end surface 313 of the distal end portion 31 is at the same position as the portion located on the othermost side of the facing surface 215A in the X-axis direction, but is not limited to this configuration. For example, as shown in FIG. 10, the tip surface 313 may be located on the other side of the facing surface 215A in the X-axis direction (in the example shown in FIG. 10, the tip portion 31 is entirely X-axis from the facing surface 215A. Located on the other side of the direction).

  Moreover, the front end surface 313 may be located on one side in the X-axis direction from the portion located on the most other side of the facing surface 215A. Even with such a configuration, similarly to the power feeder 1 of the above-described embodiment, the protrusion of the tip portion 31 from the opposite surface 215A in the state where the tip portion 31 is fitted into the fitting portion 218 is prevented, Thereby, the dimension of the X-axis direction of the electric power feeder 1 can be suppressed.

  In the electric power feeder 1 of the said embodiment, although the opposing surface 215A is dented in the whole spherical shape, it is not limited to this structure. Only a part of the facing surface 215A (a region adjacent to the tip portion 31) may be recessed. Even in such a configuration, a portion where the finger can be easily put on the peripheral edge of the tip portion 31 (a portion protruding from the facing surface 215 </ b> A of the tip portion 31: the protruding portion 315) is formed. The advance / retreat member 3 is easily pulled out even in the fitted state.

  In the power feeder 1 of the above embodiment, the distal end surface 313 of the distal end portion 31 is a plane orthogonal to the central axis C (a surface extending in the YZ plane direction), but is not limited to this configuration. As shown in FIG. 11, the front end surface 313 may be curved. Further, the tip surface 313 may be subjected to anti-slip processing (for example, knurling).

  Further, in the power feeder 1 of the above-described embodiment, the end portion 31A (outer end surface 311) on one side in the Z-axis direction of the tip portion 31 is released, that is, faces the outer side from the peripheral side of the facing surface 215A. It is not limited to this configuration. In the Z-axis direction, one end portion 31A (outer end surface 311) of the tip portion 31 may be covered with the case main body 211 or the like (see FIG. 9).

  In the power feeder 1 of the above-described embodiment, the other end portion 31B (terminal insertion hole side end surface 312) of the distal end portion 31 in the Z-axis direction faces the terminal insertion hole 217, but is not limited to this configuration. The distal end portion 31 may not face the terminal insertion hole 217. That is, the other end portion 31B (terminal insertion hole side end surface 312) in the Z-axis direction of the distal end portion 31 may be covered with the closing portion 215 or the like.

  Moreover, in the electric power feeder 1 of the said embodiment, although the advance / retreat member 3 advances / retreats by a slide, it is not limited to this structure. For example, the advancing / retracting member 3 may have a male screw portion and may be screwed into a screw hole provided in the closing portion 215 or the like. Also with this configuration, the advance / retreat member 3 can be advanced / retracted with respect to the facing surface 215A by rotating the advance / retreat member 3 around the central axis of the male screw portion.
