  However, when the battery pack connection connector having the clip terminal as in Patent Document 1 is used, the clip terminal and the extended terminal portion are rubbed with the attachment / detachment of the battery pack connection connector. As the connector is repeatedly used, the contact surface of the clip terminal is worn, and the variation in contact resistance tends to increase. In particular, in an in-vehicle battery pack, since a large current flows through the clip terminal and the extension terminal portion, the contact resistance between the clip terminal and the extension terminal portion is low and varies in order to appropriately perform inspection and the like. It is necessary to suppress it. For this reason, the battery pack connector has to be periodically replaced with a new one according to the wear of the clip terminal.

  The present invention has been made in view of such a situation, and a battery pack connecting connector that suppresses the wear of the contact terminal portion of the connector terminal member with the attachment / detachment of the connector and suppresses the variation in contact resistance. The purpose is to provide.

One aspect of the present invention for solving the above problems is a battery terminal member including a cylindrical terminal housing extending from a pack casing, and an extending terminal portion extending from the pack casing into the inner space of the terminal housing. A battery pack connecting connector that is detachably coupled to the battery connector portion and is electrically connected to the extended terminal portion of the battery terminal member, the battery housing being connected to the terminal housing. A tubular connector housing having a lockable form, wherein the connector removal direction coincides with the extension direction of the extension terminal portion, and the connector mounting direction coincides with the opposite extension direction opposite to the extension direction; A pair of contact terminal portions held by the connector housing and disposed inside the connector housing, wherein the connector housing is A separated state in which the pair of contact terminal portions are separated from each other via the extended terminal portion, and the pair of contact terminal portions sandwich the extended terminal portion with the extended terminal portion interposed therebetween. A connector terminal member configured to be able to switch between a conductive state electrically connected to the extension terminal portion, and disposed in the connector removal direction with respect to the connector terminal member , and moved in the connector mounting direction and the connector removal direction. When the operating portion held in the connector housing in a possible form and operated by a finger is moved in the connector mounting direction in the locked state, the connector terminal member is switched from the separated state to the conductive state, and the operation is performed. When the part is moved in the connector removal direction in the locked state, the connector terminal member is separated from the conductive state. A switching member which is configured to switch to state a battery pack connector comprising a.

  When the above battery pack connector (hereinafter also simply referred to as “connector”) is attached to the battery connector portion of the battery pack, the operation portion of the switching member is previously set in the connector removal direction (hereinafter simply referred to as “removal direction”). The connector that has been moved to the connector mounting direction (hereinafter also simply referred to as “mounting direction”) is moved to lock the connector housing of the connector to the terminal housing of the battery connector portion. In that case, a pair of contact terminal part of a connector terminal member is arrange | positioned in the spaced-apart state mutually spaced apart via the extension terminal part of a battery terminal member. Subsequently, when the operation portion of the switching member is moved in the mounting direction and the connector terminal member is switched from the separated state to the conductive state, the pair of contact terminal portions are electrically connected to the extended terminal portion with the extended terminal portion interposed therebetween. For this reason, when attaching a connector to a battery connector part, it can suppress that the contact terminal part of a connector terminal member and the extended terminal part of a battery terminal member rub against, and a contact terminal part wears.

On the other hand, when removing the connector from the battery connector portion, first, the operation portion of the switching member is moved in the removal direction to switch the connector terminal member from the conducting state to the separated state. Thereby, a pair of contact terminal part is spaced apart from the extended terminal part, respectively. Subsequently, the connector is moved in the removal direction, the connector housing is separated from the terminal housing, and the connector is removed from the battery connector portion. For this reason, also when removing a connector from a battery connector part, it can suppress that the contact terminal part of a connector terminal member and the extended terminal part of a battery terminal member rub against, and a contact terminal part wears.
Thus, the above-described battery pack connector can suppress the contact terminal portion of the connector terminal member from being worn as the connector is attached and detached, and can prevent the contact resistance from fluctuating.

  In addition, in the above-described connector, the operation direction of the operation portion of the switching member matches the connector mounting direction and the connector removal direction. That is, when the connector is mounted, the locking of the connector housing to the terminal housing and the movement of the operating portion in the mounting direction (switching from the separated state of the connector terminal member to the conductive state) are continuously performed in the same direction. This can be done with When removing the connector, the movement of the operation unit in the removal direction (switching the connector terminal member from the conductive state to the separated state) and the separation of the connector housing from the terminal housing are continuously performed in the same direction. Can be done. For this reason, workability | operativity at the time of attaching / detaching a connector is good.

The “battery pack connector” is connected to, for example, a cable or a conductive member that conducts to the connector terminal member and extends from the connector housing to the outside.
Examples of the “extension terminal portion” of the battery terminal member include a flat extension terminal portion and a rod-like extension terminal portion.

FIG. 3 shows a longitudinal sectional view of a battery pack connector (hereinafter also simply referred to as “connector”) 1 according to the present embodiment.

  First, the battery pack 200 will be described (see FIG. 1). The battery pack 200 is an in-vehicle high voltage battery pack mounted on a vehicle such as a hybrid car, a plug-in hybrid car, or an electric vehicle. The battery pack 200 includes a plurality of batteries 210 that are all connected in series. Each battery 210 is a square and sealed lithium ion secondary battery. The total positive electrodes 210 x of these batteries 210 are connected to a positive battery connector (battery connector) 230 through a relay 221 in the relay unit 220. On the other hand, the total negative electrode 210 y of these batteries 210 is connected to the negative battery connector part (battery connector part) 240 via the relay 223 of the fuse 227 and the relay part 220.

  The relay unit 220 includes three relays 221, 222, and 223 that are turned on / off by a signal from an external ECU, and a resistance element 225. In addition, since the positive electrode battery connector part 230 and the negative electrode battery connector part 240 have the same structure, the same components are used as the battery connector parts 230 and 240 without distinguishing between positive and negative in the following. I will explain.

  Battery connector portions 230 and 240 (see FIG. 2) are respectively provided in a resin-made pack casing 250 that accommodates each battery 210, relay portion 220, and the like, and protrudes to the outside. Specifically, the battery connector portions 230 and 240 have a terminal housing 231 and a battery terminal member 233. Of these, the terminal housing 231 is made of resin, and is formed in one piece with the pack casing 250 and has a rectangular cylindrical shape extending from the pack casing 250 to the outside. On the other hand, the battery terminal member 233 is made of copper and has a gold plating layer formed on the surface thereof. The battery terminal member 233 extends from the pack casing 250 through the pack casing 250 into the inner space NC of the terminal housing 231 and extends in a rectangular flat plate shape extending in the extending direction EH (upward in FIG. 2). A terminal portion 235 is provided. A direction opposite to the extending direction EH (downward in FIG. 2) is defined as an anti-extending direction FH.

Next, the connector 1 will be described (see FIGS. 3 to 5). In addition, since the positive electrode battery connector part 230 and the negative electrode battery connector part 240 have the same structure as mentioned above, the connector 1 connected to these is also a connector which has the same structure. Accordingly, the following description will be made using the same reference numerals without distinguishing between positive and negative connectors.
The connector 1 is detachably coupled to the battery connector portions 230 and 240 and is electrically connected to the extended terminal portion 235 of the battery terminal member 233. When the connector 1 is attached or detached, the connector mounting direction AH (downward in FIGS. 3 to 5, hereinafter, also simply referred to as “mounting direction AH”) and the extended terminal portions 235 of the battery connector portions 230 and 240 are used. Of the extension terminal portion 235 and the extension direction EH of the extension terminal portion 235, and the extension direction EH of the extension terminal portion 235. Match.

  The connector 1 includes a connector housing 10, a connector terminal member 20, and a switching member 30. Among these, the connector housing 10 is made of resin, and includes a rectangular flat plate-like wall portion 11 and a rectangular tubular portion 13 extending from the periphery of the wall portion 11 in the mounting direction AH. A step portion 13 d is formed on the inner end portion of the cylindrical portion 13 over the entire circumference. As will be described later, the step portion 231s of the terminal housing 231 of the battery connector portion 230, 240 is fitted into the step portion 13d.

  The connector terminal member 20 has a pair of terminal members 21 and 22 arranged in the mounting direction AH inside the connector housing 10. These terminal members 21 and 22 are made of copper, and a gold plating layer is formed on the surface thereof. Each of the terminal members 21 and 22 includes contact terminal portions 21s and 22s, base end portions 21k and 22k, and support portions 21c and 22c. Of these, the contact terminal portions 21 s and 22 s are rectangular flat portions extending from the support portions 21 c and 22 c toward the mounting direction AH and forming the tip portions of the terminal members 21 and 22. It extends beyond the connector 13 to the tip end side (mounting direction AH side) outside the connector housing 10. On the other hand, the base end portions 21k and 22k are rectangular flat portions extending from the support portions 21c and 22c toward the removal direction BH. Further, the support portions 21c and 22c are located between the contact terminal portions 21s and 22s and the base end portions 21k and 22k and connect them, and pass through in a direction orthogonal to the paper surface in FIGS. Through-holes 21ch and 22ch.

3 to 5, the pin 23 is inserted into the through holes 21ch and 22ch in a state where the support portions 21c and 22c of the terminal members 21 and 22 are overlapped in a direction orthogonal to the paper surface. , 22 are coupled so as to be rotatable about the pin 23 as a fulcrum. Although not shown, both ends of the pin 23 are held by the connector housing 10, whereby the connector terminal member 20 including the terminal members 21 and 22 is held by the connector housing 10. Although not shown, a cable conductor is connected to one terminal member 21, and this cable extends from the connector housing 10 to the outside.
In the present embodiment, the terminal member 21 and the terminal member 22 coupled by the pin 23 are arranged in parallel. That is, the contact terminal portion 21 s and the base end portion 21 k of one terminal member 21 are both arranged on the left side in FIGS. 3 to 5 with respect to the pin 23, and the contact terminal portion 22 s and the base end of the other terminal member 22 are disposed. The part 22k is arranged on the right side in FIGS.

  A spring 25 is attached between the base end portions 21k, 22k of the terminal members 21, 22. Thus, in a state where the switching member 30 described below is not in contact with the terminal members 21 and 22 (see FIG. 3), the spring 25 becomes a free length, and the base end portions 21k and 22k of the terminal members 21 and 22 are A predetermined gap (gap Lb between the base ends 21 kt and 22 kt) is spaced apart. Accordingly, the contact terminal portions 21s and 22s are separated from each other with a predetermined gap (gap La between the tips 21st and 22st).

  On the other hand, in a state in which the pushing portion 33 of the switching member 30 described below is pushed between the base end portions 21k and 22k of the terminal members 21 and 22 (see FIG. 5), the spring 25 is extended and the base end portion 21k, The gap between 22k is expanded (gap Ld, Ld> Lb between base ends 21kt and 22kt). Accordingly, the base end portion 21k of one terminal member 21 moves to the left in the counterclockwise direction in FIGS. 3 to 5 with the pin 23 as a fulcrum, so that the contact terminal portion 21s of the terminal member 21 has the pin 23 as a fulcrum. 3 to 5 in FIG. 3 to FIG. Further, since the base end portion 22k of the other terminal member 22 moves clockwise in FIGS. 3 to 5 with the pin 23 as a fulcrum, the contact terminal portion 22s of the terminal member 22 is illustrated with the pin 23 as a fulcrum. 3 to the left in FIG. For this reason, when the gap between the base end portions 21k and 22k is increased, the gap between the contact terminal portions 21s and 22s is conversely narrowed (the gaps Lc and Lc <La of the tips 21st and 22st). Thus, the connector terminal member 20 is configured to be able to widen or narrow the gap between the contact terminal portions 21s and 22s.

  The switching member 30 is made of an insulating resin, and includes an operation unit 31 that is operated with fingers, a push-in unit 33, and a connection unit 35 that connects between these. The switching member 30 is arranged in the order of the pushing portion 33, the connecting portion 35, and the operating portion 31 in the removing direction BH from the connector terminal member 20, and is held by the connector housing 10. The operation unit 31 has a disk shape and is disposed outside the connector housing 10 in the removal direction BH. On the other hand, the push-in portion 33 is a portion having a cross-sectional shape that becomes narrower toward the mounting direction AH, and is disposed inside the connector housing 10. The connecting portion 35 has a rod shape, extends from the operation portion 31 in the mounting direction AH, passes through the wall portion 11 of the connector housing 10, and is connected to the pushing portion 33.

As shown in FIG. 3, the switching member 30 moves the operation portion 31 in the removal direction BH (upward in the drawing) (pulls in the removal direction BH), and pushes the pushing portion 33 into the wall portion of the connector housing 10. 11, the pushing portion 33 is separated from the connector terminal member 20.
On the other hand, in a state where the operation unit 31 is moved in the mounting direction AH (downward in the drawing) (pressed in the mounting direction AH) and the operation unit 31 is in contact with the wall 11 of the connector housing 10 (see FIG. 5), the pushing portion 33 is pushed between the base end portions 21k and 22k of the pair of terminal members 21 and 22 of the connector terminal member 20, and the gap between the base end portions 21k and 22k is widened. Then, as described above, the gap between the contact terminal portions 21s and 22s is narrowed. As described above, the switching member 30 is configured to be able to widen or narrow the gap between the contact terminal portions 21 s and 22 s of the connector terminal member 20 by operating the operation portion 31.

  Next, attachment / detachment of the connector 1 to / from the battery connector portions 230 and 240 of the battery pack 200 will be described. When the connector 1 is attached to the battery connector portions 230 and 240, as shown in FIG. 4, the operating portion 31 of the switching member 30 is moved in the removal direction BH in advance, so that the pushing portion 33 is separated from the connector terminal member 20. Leave it in the state. Then, the connector 1 is moved in the mounting direction AH, and the connector housing 10 is locked to the terminal housings 231 of the battery connector portions 230 and 240. Specifically, the tip portion 231s of the terminal housing 231 is fitted to the step portion 13d of the connector housing 10 over the entire circumference. In this state, the pair of contact terminal portions 21 s and 22 s of the connector terminal member 20 are disposed in a separated state via the extended terminal portion 235 of the battery terminal member 233.

  Subsequently, as shown in FIG. 5, when the operating portion 31 of the switching member 30 is moved in the mounting direction AH, the pushing portion 33 of the switching member 30 is interposed between the base end portions 21 k and 22 k of the terminal members 21 and 22. By being pushed in, the gap between the base end portions 21k and 22k is expanded. Then, the gap between the contact terminal portions 21 s and 22 s is narrowed, and the contact terminal portions 21 s and 22 s are brought into contact with the main surfaces of the extended terminal portion 235 with the extended terminal portion 235 interposed therebetween, and are electrically connected from the separated state. Switch to state. Thus, the connector terminal member 20 of the connector 1 is electrically connected to the battery terminal member 233 of the battery connector portions 230 and 240. Since the connector 1 of this embodiment is mounted in this way, it is possible to suppress the contact terminal portions 21s, 22s and the extended terminal portion 235 from rubbing against wear of the contact terminal portions 21s, 22s.

  On the other hand, when the connector 1 is removed from the battery connector portions 230 and 240, first, when the operation portion 31 of the switching member 30 is moved in the removal direction BH, the base end portions 21k and 22k of the terminal members 21 and 22 are connected to each other. The pushing portion 33 that has been pushed into the position moves in the removal direction BH and leaves the terminal members 21 and 22 (see FIG. 4). Then, the extended spring 25 is returned to the free length, and the interval between the base end portions 21k and 22k of the terminal members 21 and 22 is narrowed, and conversely, the gap between the contact terminal portions 21s and 22s is expanded. Then, the contact terminal portions 21s and 22s are separated from the extended terminal portion 235, respectively, and are switched from the conductive state to the separated state.

  Subsequently, the connector 1 is moved in the removal direction BH, the connector housing 10 is separated from the terminal housing 231, and the connector 1 is detached from the battery connector portions 230 and 240. Since the connector 1 of this embodiment is removed in this manner, the contact terminal portions 21s and 22s of the connector terminal member 20 and the extended terminal portion 235 of the battery terminal member 233 are rubbed to wear the contact terminal portions 21s and 22s. Can be suppressed.

  As described above, when the connector 1 is attached to the battery connector portions 230 and 240, the connector 1 is moved in the attachment direction AH while the operation portion 31 of the switching member 30 is moved in the removal direction BH. Then, the connector housing 10 is locked to the terminal housing 231. At that time, the pair of contact terminal portions 21 s and 22 s of the connector terminal member 20 are arranged in a separated state through the extended terminal portion 235 of the battery terminal member 233. Subsequently, when the operation portion 31 of the switching member 30 is moved in the mounting direction AH and the connector terminal member 20 is switched from the separated state to the conductive state, the pair of contact terminal portions 21 s and 22 s sandwich the extended terminal portion 235. The extended terminal portion 235 is electrically connected. For this reason, when the connector 1 is mounted on the battery connector portions 230 and 240, the contact terminal portions 21s and 22s of the connector terminal member 20 and the extended terminal portion 235 of the battery terminal member 233 are rubbed to cause contact terminal portions 21s and 22s. Can be prevented from being worn.

  On the other hand, when the connector 1 is detached from the battery connector portions 230 and 240, first, the operation portion 31 of the switching member 30 is moved in the removal direction BH to switch the connector terminal member 20 from the conducting state to the separated state. Thereby, a pair of contact terminal parts 21s and 22s are spaced apart from the extended terminal part 235, respectively. Subsequently, the connector 1 is moved in the removal direction BH, the connector housing 10 is separated from the terminal housing 231, and the connector 1 is detached from the battery connector portions 230 and 240. For this reason, even when the connector 1 is detached from the battery connector portions 230 and 240, the contact terminal portions 21s and 22s of the connector terminal member 20 and the extended terminal portion 235 of the battery terminal member 233 are rubbed to rub the contact terminal portions 21s and 22s. Can be prevented from being worn. Thus, the connector 1 can suppress the contact terminal portions 21 s and 22 s of the connector terminal member 20 from being worn with the attachment and detachment of the connector 1, and can suppress the contact resistance from fluctuating.

  In addition, in the connector 1, the operation direction of the operation unit 31 of the switching member 30 matches the mounting direction AH and the removal direction BH. That is, when the connector 1 is mounted, the connector housing 10 is locked to the terminal housing 231 and the operation unit 31 is moved in the mounting direction AH (switching from the separated state of the connector terminal member 20 to the conductive state). Can be performed in a continuous operation in the same direction. Further, when the connector 1 is removed, the movement of the operation portion 31 to the removal BH (switching from the conductive state of the connector terminal member 20 to the separated state) and the separation of the connector housing 10 from the terminal housing 231 are the same. This can be done in a continuous motion in the direction. For this reason, workability | operativity at the time of attaching / detaching the connector 1 is good.

(Deformation)
Next, modifications of the above-described embodiment will be described. In the connector 1 according to the embodiment (see FIGS. 3 to 5), when the operation portion 31 of the switching member 30 is moved in the mounting direction AH, the base end portions 21 k and 22 k of the pair of terminal members 21 and 22 of the connector terminal member 20. The gap between the contact terminals 21s and 22s is narrowed while the gap between them is widened. On the other hand, in the connector 101 (see FIGS. 6 to 8) of this modification, when the operation unit 31 of the switching member 130 is moved in the mounting direction AH, the base of the pair of terminal members 121 and 122 of the connector terminal member 120 is changed. The gap between the end portions 121k and 122k is narrowed, and the gap between the contact terminal portions 121s and 122s is also narrowed.

  The connector 101 of this modification includes a connector terminal member 120 and a switching member 130 in addition to the connector housing 10 similar to that of the embodiment. Among these, the connector terminal member 120 has a pair of terminal members 121 and 122 arranged in the mounting direction AH inside the connector housing 10. Each terminal member 121, 122 includes contact terminal portions 121s, 122s located on the mounting direction AH side, base end portions 121k, 122k located on the removal direction BH side, and support portions 121c, 122c located therebetween. Consists of. 6 to 8, the pin 123 is inserted into the through holes 121ch and 122ch in a state where the support portions 121c and 122c of the terminal members 121 and 122 are overlapped in a direction orthogonal to the paper surface. , 122 are coupled so as to be rotatable about the pin 123 as a fulcrum. Further, as in the embodiment, both end portions of the pin 123 are respectively held by the connector housing 10.

  However, in the above-described embodiment, the terminal member 21 and the terminal member 22 joined by the pin 23 are arranged in parallel. On the other hand, in this modified embodiment, the terminal member 121 and the terminal member 122 coupled by the pin 123 intersect with each other with the pin 123 as the center. That is, the base end portion 121k of one terminal member 121 is disposed on the left side in FIGS. 6 to 8 with respect to the pin 123, but the contact terminal portion 121s of the terminal member 121 is conversely illustrated with respect to the pin 123. 6 to 8 are arranged on the right side. Further, the base end portion 122k of the other terminal member 122 is arranged on the right side in FIGS. 6 to 8 with respect to the pin 123, but the contact terminal portion 122s of the terminal member 122 is conversely shown in FIG. 6 to 8 are arranged on the left side.

  In addition, a spring 125 is attached between the base end portions 121k and 122k of the terminal members 121 and 122. Thereby, in a state where the switching member 130 described below is not in contact with the terminal members 121 and 122 (see FIG. 6), the spring 125 becomes a free length, and the base end portions 121k and 122k of the terminal members 121 and 122 are The contact terminal portions 121 s and 122 s are spaced apart by a predetermined gap (gap Le between the base ends 121 kt and 122 kt), and the contact terminal portions 121 s and 122 s are spaced apart by a gap similar to the embodiment (the gap La between the distal ends 121 st and 122 st).

  On the other hand, in a state in which the pushing portion 133 of the switching member 130 described below is pushed and pressed against the base end portions 121k and 122k of the terminal members 121 and 122 (see FIG. 8), the spring 125 is contracted and the base end portions 121k and 122k. The gap between each other is narrowed (gap Lf, Lf <Le between the base ends 121 kt and 122 kt). As a result, the base end portion 121k of one terminal member 121 moves to the right in the clockwise direction in FIGS. 6 to 8 with the pin 123 as a fulcrum, so that the contact terminal portion 121s of this terminal member 121 has the pin 123 as a fulcrum. 6-8, it moves to the left in the clockwise direction. Further, since the base end portion 122k of the other terminal member 122 moves counterclockwise in FIGS. 6 to 8 with the pin 123 as a fulcrum, the contact terminal portion 122s of the terminal member 122 has the pin 123 as a fulcrum. 6-8, it moves to the right counterclockwise. For this reason, in this modification, when the gap between the base end portions 121k and 122k is narrowed, the gap between the contact terminal portions 121s and 122s is also narrowed.

  The switching member 130 includes a pushing portion 133 in addition to the operation portion 31 and the connecting portion 35 similar to those in the embodiment. This pushing portion 133 has a concave cross-sectional shape that opens in the left-right direction in FIGS. 6 to 8 as it goes in the mounting direction AH. As shown in FIG. 6, the switching member 130 moves the operating portion 31 in the removal direction BH, and in a state where the pushing portion 133 is in contact with the wall portion 11 of the connector housing 10, the pushing portion 133 is It is separated from the connector terminal member 120. On the other hand, in a state where the operation unit 31 is moved in the mounting direction AH and is in contact with the wall 11 of the connector housing 10 (see FIG. 8), the push-in unit 133 is a pair of terminal members 121, Since it press-contacts so that it may pinch | interpose into the base end parts 121k and 122k of 122 from the outer side (FIG. 6-8 right-and-left direction), the clearance gap between base end parts 121k and 122k becomes narrow. Then, as described above, the gap between the contact terminal portions 121s and 122s is also narrowed.

  Next, attachment / detachment of the connector 101 to / from the battery connector portions 230 and 240 will be described. When attaching the connector 101 to the battery connector portions 230 and 240, as shown in FIG. 7, the operating portion 31 of the switching member 130 is moved in the removal direction BH in advance, so that the pushing portion 133 is separated from the connector terminal member 120. Leave it in the state. Then, the connector 101 is moved in the mounting direction AH, and the connector housing 10 is locked to the terminal housing 231. In this state, the pair of contact terminal portions 121 s and 122 s of the connector terminal member 120 are arranged in a spaced apart state via the extended terminal portion 235 of the battery terminal member 233. Subsequently, as shown in FIG. 8, when the operation portion 31 is moved in the mounting direction AH, the pushing portion 133 sandwiches the base end portions 121k and 122k of the terminal members 121 and 122 from the outside, and the base end portions 121k and 122k are connected to each other. Narrow the gap. Then, the gap between the contact terminal portions 121 s and 122 s also narrows, and the contact terminal portions 121 s and 122 s are brought into contact with the main surfaces of the extended terminal portion 235 with the extended terminal portion 235 interposed therebetween, and are switched to a conductive state. .

  On the other hand, when the connector 101 is detached from the battery connector portions 230 and 240, first, when the operation portion 31 is moved in the removal direction BH, the pushing portion that is in pressure contact with the base end portions 121k and 122k of the terminal members 121 and 122 is used. 133 moves in the removal direction BH and moves away from the terminal members 121 and 122 (see FIG. 7). Then, the contracted spring 125 returns to the free length, and the interval between the base end portions 121k and 122k is expanded, so that the gap between the contact terminal portions 121s and 122s is also expanded. Then, the contact terminal portions 121s and 122s are separated from the extended terminal portion 235, respectively, and are switched from the conductive state to the separated state. Subsequently, the connector 101 is moved in the removal direction BH, the connector housing 10 is separated from the terminal housing 231, and the connector 101 is detached from the battery connector portions 230 and 240.

  As described above, when the connector 101 of this modified embodiment is also attached to and removed from the battery connector portions 230 and 240, the contact terminal portions 121s and 122s of the connector terminal member 120 and the extended terminal portion 235 of the battery terminal member 233 The contact terminal portions 121s and 122s can be prevented from being worn by rubbing, and the contact resistance can be prevented from fluctuating. In addition, similarly to the connector 1 of the embodiment, the connector 101 of the present modified embodiment also attaches and detaches the connector 101 because the operation direction of the operation unit 31 of the switching member 130 matches the mounting direction AH and the removal direction BH. Good workability.

  In the above, the present invention has been described with reference to the embodiments and modified embodiments. However, the present invention is not limited to the above-described embodiments and modified embodiments, and can be appropriately modified and applied without departing from the gist thereof. Needless to say, you can.
