AI Technical Summary
Existing connectors with CPA members often experience unintentional deflection of the CPA arm during transportation, which can lead to deformation and premature release of the temporary locking state, preventing proper mating with the counterpart connector.
The connector design includes a CPA body with cantilever CPA arms that are temporarily locked by CPA-side protrusions on the housing, preventing unintended deflection and ensuring the CPA arm remains locked until intentional release during mating.
This design effectively suppresses unintentional deflection of the CPA arm, maintaining the temporary locking state until intended release, thereby ensuring reliable mating and preventing deformation of the CPA arm.

Abstract
Description
[Technical field]
[0001] This relates to a connector in which a CPA (Connector Position Assurance) component is attached to the connector body to ensure proper mating with the mating connector. [Background technology]
[0002] Conventionally, connectors are known in which a CPA member is attached to the connector body to ensure mating with the mating connector (see, for example, Patent Document 1). The CPA member in Patent Document 1 is attached to the housing in a provisionally locked state, and movement in the mating direction is prohibited before mating. When the connector body and the mating connector are mated, the prohibition of the CPA member is lifted and the CPA member becomes movable. When mating is complete, the worker moves the CPA member, which has become movable, to a fully locked state. With this connector, mating with the mating connector is guaranteed because the CPA member is in the fully locked state.
[0003] In the above CPA member, the prohibition of movement in the provisionally locked state and the final locking to the housing in the final locked state are performed by a CPA arm formed in a cantilever shape. In the provisionally locked state, the tip of the CPA arm abuts against the housing to prohibit the CPA member from moving. When the mating connector is mated, the CPA arm is bent, and the tip is released from the housing, releasing the prohibition of movement, allowing the CPA member to be moved by the operator.

[0004] [Patent Document 1] JP 2020-072013 A Summary of the Invention [Problem to be solved by the invention]
[0005] In many connectors with CPA members as described above, the CPA member is attached in a provisionally locked state and transported. When such connectors are transported, some external force may be applied to the CPA arm, causing the CPA arm to bend. Such unintended bending of the CPA arm is undesirable because it may cause deformation of the CPA arm if the bending is too large, or the prohibition on movement of the CPA member in the provisionally locked state may be released before mating with the mating connector.
[0006] Therefore, the present invention focuses on the above-mentioned problems and aims to provide a connector that can suppress unintended bending of a CPA arm in a CPA member in a partially engaged state. [Means for solving the problem]
[0007] In order to solve the above problems, a connector includes a connector body having connector terminals accommodated in cavities in a housing, and a CPA member that is attached to the housing in a provisionally locked state, and is prohibited from moving in a moving direction along a mating direction before the connector body is mated with a mating connector, and when the prohibition is released upon mating, moves in the moving direction to a final locked state, thereby ensuring the mating, wherein the CPA member provisionally locks to the housing, and is operated to move to the final locked state at a rear side in the moving direction, a CPA arm that is a cantilever extending from the CPA body in the moving direction, and which abuts against the housing at an end on the free end side to prohibit the movement before mating, and is finally locked to the housing at the end when the prohibition is released upon mating, and a pair of CPA arms and a pair of CPA side protrusions protruding in the width direction of the CPA arm from a midpoint between the fixed end side and the free end side at each side edge of the housing, and the housing is characterized in that it comprises a housing main body in which the cavity is provided, a CPA receiving space that receives the CPA member with a CPA moving surface, on the outer surface of the housing main body, along which the CPA member moves, as its bottom surface, and a CPA receiving portion to which the CPA main body is temporarily engaged in the temporary engagement state and to which the end of the CPA arm is permanently engaged in the full engagement state, and a pair of housing side protrusions formed on the CPA moving surface at positions that do not overlap with the CPA arm in a planar view relative to the CPA moving surface, abut against the pair of CPA side protrusions in the temporary engagement state, and are disengaged from the pair of CPA side protrusions in the full engagement state. Effect of the Invention
[0008] According to the above connector, unintended bending of the CPA arm in the CPA member in the partially locked state can be suppressed. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] An embodiment of the connector will now be described.
[0011] FIG. 1 is an exploded perspective view showing a connector according to one embodiment together with a mating connector.
[0012] The connector 1 in this embodiment is used as an end connector of a wire harness mounted on a vehicle or the like. The mating connector 2 is attached to a mating device or a mating wire harness to which the wire harness is connected. In this embodiment, the connector 1 is a female connector having a rectangular block-like appearance, and the mating connector 2 is a rectangular block-like male connector to which the connector 1 can be connected.
[0013] The connector 1 includes a connector body 11 and a CPA member 12. The connector body 11 has a housing 11a with a cavity 111a housing a connector terminal 11b. The housing 11a has a rectangular block-like appearance and is made of insulating resin with a plurality of rectangular cylindrical cavities 111a formed therein. The connector terminal 11b is a female terminal made of conductive metal and formed into a rectangular cylindrical shape by sheet metal processing, and is crimped and connected to an end of the electric wire W1. The connector terminals 11b are housed one by one in the cavities 111a of the housing 11a.
[0014] The connector body 11 also includes a spacer 11c. The spacer 11c is an insulating resin member that is inserted through a slit formed in one side of the rectangular block-shaped housing body 111. When the spacer 11c is inserted into the housing body 111, the connector terminals 11b in each cavity 111a are pressed in the insertion direction, and each connector terminal 11b is fixed so as not to come out of each cavity 111a.
[0015] The CPA member 12 is a resin member that is attached to the housing main body 111 in a provisionally locked state and that ensures the fitting by transitioning to a fully locked state after the connector main body 11 is fitted to the mating connector 2. The CPA member 12 is prohibited from moving in a movement direction D12 along the fitting direction D11 before the connector main body 11 is fitted to the mating connector 2, and this prohibition is lifted upon fitting. When the fitting of the connector main body 11 to the mating connector 2 is completed, the worker confirms the fitting by pushing the CPA member 12 in the movement direction D12 to transition to the fully locked state.
[0016] The housing 11a of the connector body 11 includes a housing main body 111 in which a cavity 111a is provided, and a CPA receiving portion 112 that receives the CPA member 12. The CPA receiving portion 112 defines a CPA receiving space 112b that receives the CPA member 12 with a CPA moving surface 112a, along which the CPA member 12 moves, serving as a bottom surface among the outer peripheral surfaces of the housing main body 111. The CPA receiving portion 112 includes a pair of side wall ribs 112c erected on a pair of side edges along the moving direction D12 of the CPA moving surface 112a, and a fitting lock arm 112d that is stretched between the pair of side wall ribs 112c so as to face the CPA moving surface 112a.
[0017] The mating lock arm 112d is connected to a pair of sidewall ribs 112c at the rear side in the moving direction D12, connected to the CPA moving surface 112a at the front side, and configured to be flexible at the center. The mating lock arm 112d has a pair of arm portions 112d-1 each extending along the sidewall rib 112c, connected to the sidewall rib 112c at the rear side in the moving direction D12, and connected to the CPA moving surface 112a near the sidewall rib 112c at the front side. A lock bridge 112d-2 is spanned across the center of the pair of arm portions 112d-1. When mating with the mating connector 2, the mating connector 2 is locked to a lock end face 112d-2a, which is the end face on the rear side in the moving direction D12 of the lock bridge 112d-2, to stabilize the mating state.
[0018] Furthermore, on the rear side of the lock bridge 112d-2, an unlocking operation receiving portion 112d-3 is provided between the pair of arm portions 112d-1 in a bridge shape. This unlocking operation receiving portion 112d-3 receives an unlocking operation from an operator at the time of disengagement, which bends the mating lock arm 112d to remove the lock end surface 112d-2a from the mating connector 2. The unlocking operation receiving portion 112d-3 is formed so that its height from the CPA moving surface 112a is higher than that of the lock bridge 112d-2 so that it can easily receive the unlocking operation from the operator.
[0019] The CPA member 12 is a member having a generally rectangular plate-like appearance, and is inserted into the CPA receiving space 112b by being inserted between the CPA moving surface 112a and the mating lock arm 112d in the CPA receiving portion 112. Then, before mating with the mating connector 2, the CPA member 12 is in the following provisionally locked state in the CPA receiving space 112b.
[0020] Fig. 2 is a cutaway perspective view showing a state in which the CPA member is attached in a provisionally locked state to the CPA receiving space shown in Fig. 1, along with a cross section passing through the mating lock arm, and Fig. 3 is a cross-sectional view showing the cross section shown in Fig. 2. The CPA member 12 will be described below with reference to Figs. 2 and 3 as well as Fig. 1.
[0021] First, the CPA member 12 is provided with a CPA body 121 formed in a rectangular frame shape and provided with a full-locking operation receiving portion 121a that receives a transition operation to a full-locking state on the rear side in the movement direction D12 along the fitting direction D11. A pair of side frame portions 121b of the CPA body 121 along the movement direction D12 are provided on the outer surfaces of the respective side frames 121b, which are provided with CPA-side temporary-locking projections 121c for temporary locking with the housing 11a. The CPA receiving portion 112 in the housing 11a is provided with a housing-side temporary-locking projection 112e on which the CPA-side temporary-locking projections 121c are engaged, on the inner surfaces of the respective side wall ribs 112c. The pair of CPA-side temporary-locking projections 121c engage with the pair of housing-side temporary-locking projections 112e, whereby the CPA body 121, i.e., the CPA member 12, is temporarily locked to the housing 11a.
[0022] The CPA member 12 also includes a cantilever-like CPA arm 122 that extends in the moving direction D12 inside the rectangular frame-like CPA body 121. The CPA arm 122 has a fixed end at the rear side in the moving direction D12 and a free end at the front side. An end protrusion 122a that protrudes on the opposite side to the CPA moving surface 112a is formed on the free end side of the CPA arm 122. Before mating, a movement prohibition end surface 122a-1, which is the end surface on the front side in the moving direction D12 of the end protrusion 122a, abuts against a lock end surface 112d-2a of the mating lock arm 112d of the housing 11a. By abutting the movement prohibition end surface 122a-1 against the lock end surface 112d-2a, the CPA arm 122 prohibits the movement of the CPA member 12 in the moving direction D12 in the provisionally locked state before mating.
[0023] When the mating connector 2 is mated, the mating connector 2 pushes the end protrusion 122a toward the CPA moving surface 112a, and the movement prohibition end surface 122a-1 is disengaged from the lock end surface 112d-2a, and the movement prohibition in the provisionally locked state is released. Then, when the operator puts his / her finger on the full lock operation receiving portion 121a and pushes the CPA member 12 in the moving direction D12, the end protrusion 122a of the CPA arm 122 passes through the lock bridge 112d-2 of the mating lock arm 112d to the front side in the moving direction D12. When the CPA arm 122 returns to its original position after passing through, the full lock end surface 122a-2, which is the end surface on the rear side in the moving direction D12 of the end protrusion 122a, is locked with the full lock receiving portion 112d-2b, which is the end surface on the front side in the moving direction D12 of the lock bridge 112d-2. The fully locked state of the CPA member 12 with respect to the housing 11a means a state in which the fully locked end surface 122a-2 of the CPA arm 122 is locked with the fully locked receiving portion 112d-2b of the fitting lock arm 112d. In this manner, the CPA arm 122 is fully locked with the housing 11a when the movement prohibition is released by fitting the mating connector 2.
[0024] Furthermore, the CPA arm 122 has a full-lock release receiving portion 122b formed to protrude from the outer surface opposite the CPA moving surface 112a at a midpoint between the fixed end side and the free end side. The full-lock release receiving portion 122b is a portion that receives a full-lock release operation from an operator that bends the CPA arm 122 to release the full lock of the full lock end surface 122a-2 when in the full-lock state. In the full-lock release operation, the work vehicle pushes the full-lock release receiving portion 122b toward the CPA moving surface 112a, thereby disengaging the full lock end surface 122a-2 from the full-lock receiving portion 112d-2b and releasing the full lock.
[0025] Furthermore, the CPA arm 122 is provided with a pair of CPA side projections 123. The pair of CPA side projections 123 are formed to project from the intermediate position between the fixed end side and the free end side of each of a pair of side edges 122c of the CPA arm 122 in the width direction D13 of the CPA arm 122. Each CPA side projection 123 has a shape in which a pair of corners on the CPA moving surface 112a side of the rectangular column shape are chamfered. The pair of CPA side projections 123 project from the adjacent position of the above-mentioned main lock release receiving portion 122b on each of a pair of side edges 122c of the CPA arm 122. As shown in FIG. 3, the CPA arm 122 is formed so that the length L12 of the portion from the CPA side projection 123 to the free end side is longer than the length L11 of the portion from the CPA side projection 123 to the fixed end side.
[0026] On the other hand, in the housing 11a, a pair of housing side projections 113 are formed on the CPA moving surface 112a as portions corresponding to the pair of CPA side projections 123. The pair of housing side projections 113 are provided at positions on the CPA moving surface 112a that do not overlap with the CPA arm 122 in a plan view of the CPA moving surface 112a and come into contact with the pair of CPA side projections 123 in the provisionally locked state. The formation positions of the housing side projections 113 are also positions that are disengaged from the CPA side projections 123 in the final locked state.
[0027] In this embodiment, each CPA side protrusion 123 has a chamfered portion on the front side in the movement direction D12 as a CPA front side inclined surface 123a inclined so that the distance from the CPA movement surface 112a gradually increases toward the movement direction D12. On the other hand, each housing side protrusion 113 has a housing side inclined surface 113a formed on the rear side in the movement direction D12, inclined so that the protruding height from the CPA movement surface 112a gradually increases toward the movement direction D12.
[0028] Furthermore, each CPA side protrusion 123 has a CPA rear side inclined surface 123b that is inclined so that the chamfered portion on the rear side in the movement direction D12 gradually decreases in distance from the CPA movement surface 112a toward the movement direction D12. On the other hand, each housing side protrusion 113 has a front end surface in the movement direction D12 that forms a housing side non-inclined surface 113b that rises approximately perpendicularly from the CPA movement surface 112a.
[0029] Fig. 4 is a cross-sectional view passing through the CPA arm showing the movement of each part until the CPA member reaches the final locking state after the mating connector is mated with the connector shown in Fig. 1. Fig. 5 is a cross-sectional view passing through the CPA side protrusion and the housing side protrusion of the connector that has moved to the final locking state.
[0030] 4, the CPA member 12 is attached in a provisionally locked state to the connector body 11 of the connector 1. Then, mating of the mating connector 2 to this connector 1 is started. A mating locking portion 21 that locks with the lock end face 112d-2a of the mating lock arm 112d of the housing 11a is formed at the opening on the mating side of the mating connector 2. In the first step S11, this mating locking portion 21 is in contact with the full lock receiving portion 112d-2b that is opposite to the lock end face 112d-2a of the lock bridge 112d-2.
[0031] In a second step S12 in which the mating of the mating connector 2 to the connector 1 has progressed somewhat, the mating locking portion 21 climbs up onto the lock bridge 112d-2 while bending the mating lock arm 112d toward the CPA moving surface 112a. At this time, the tip of the CPA member 12 is pushed by the lock bridge 112d-2, causing the CPA member 12 to tilt toward the CPA moving surface 112a.
[0032] In the third step S13 when the mating of the mating connector 2 to the connector 1 is completed, the mating locking portion 21 climbs over the lock bridge 112d-2 and is locked to the lock end face 112d-2a. The mating locking portion 21 then pushes the end projection 122a, whose movement prohibition end face 122a-1 was in contact with the lock end face 112d-2a in the provisionally locked state in the CPA member 12, toward the CPA movement face 112a while bending the CPA arm 122. This pushing causes the movement prohibition end face 122a-1 to come off the lock end face 112d-2a, and the movement prohibition of the CPA member 12 is released.
[0033] In a fourth step S14 after the mating of the mating connector 2 to the connector 1 is completed, the CPA member 12, whose movement prohibition has been released, is pushed in the movement direction D12 and transitions to a fully locked state. In the fully locked state, the end projection 122a of the CPA arm 122 passes through the lock bridge 112d-2, and the fully locked end face 122a-2 on the rear side in the movement direction D12 is locked to the fully locked receiving portion 112d-2b of the lock bridge 112d-2.
[0034] In this final locked state, as shown in FIG. 5, the CPA side protrusion 123 is offset from the housing side protrusion 113 toward the forward side in the movement direction D12, and a clearance d11 is formed between the CPA side protrusion 123 and the CPA movement surface 112a.
[0035] When the connector 1 and the mating connector 2 are disengaged, the CPA member 12 is first returned from the fully locked state to the provisionally locked state prior to the disengagement. At this time, the above-mentioned clearance d11 is utilized, and the fully unlocked receiving portion 122b adjacent to the CPA side projection 123 in the width direction D13 is pushed in by the operator. This pushing causes the cantilever-shaped CPA arm 122 to bend toward the CPA moving surface 112a, and the fully locked end surface 122a-2 of the end projection 122a on the tip side is disengaged from the fully locked receiving portion 112d-2b of the lock bridge 112d-2, thereby releasing the fully locked state. Thereafter, the CPA member 12 is pulled in the opposite direction to the moving direction D12 to return to the provisionally locked state, and disengagement from the mating connector 2 becomes possible.
[0036] According to the connector 1 of the embodiment described above, in the provisionally locked state, a pair of CPA side projections 123 provided on the CPA arm 122 abut against a pair of housing side projections 113 provided on the CPA moving surface 112a. This abutment suppresses unintended bending of the CPA arm 122 in the provisionally locked state. In addition, the CPA side projections 123 protrude from the side edges of the CPA arm 122 in the width direction D13, and the housing side projections 113 are provided at positions that do not overlap with the CPA arm 122. Since the CPA side projections 123 do not overlap with the CPA arm 122, bending deformation of the CPA arm 122 due to engagement with the mating connector 2 is not hindered. In addition, since the housing side projections 113 are provided at positions that are disengaged from the CPA side projections 123 in the final locked state, bending deformation of the CPA arm 122 for releasing the final engagement of the CPA member 12 is not hindered when disengaging with the mating connector 2. In this manner, according to the present embodiment, unintended bending of CPA arm 122 of CPA member 12 in the partially locked state can be suppressed without interfering with the original operation of CPA member 12.
[0037] Here, in this embodiment, a full-lock release receiving portion 122b that receives a full-lock release operation is formed to protrude from CPA arm 122, and a pair of CPA side projections 123 protrude from positions adjacent to this full-lock release receiving portion 122b. According to this configuration, CPA side projections 123 are provided at positions adjacent to full-lock release receiving portion 122b that are formed to protrude for the full-lock release operation by an operator and are more susceptible to external forces than other portions. By providing CPA side projections 123 at such positions and abutting against housing side projections 113 in the provisionally locked state, unintended deflection of CPA arm 122 when subjected to external forces can be effectively suppressed.
[0038] Furthermore, in this embodiment, CPA arm 122 is formed such that length L12 of the portion from the pair of CPA side protrusions 123 to the free end side is longer than length L11 of the portion from the pair of CPA side protrusions 123 to the fixed end side. With this configuration, the portion of CPA arm 122 from CPA side protrusions 123 that essentially functions as a cantilever in the provisionally locked state is long. Because the portion on the free end side is long, the free end side of CPA arm 122 can be effectively flexed by mating with counterpart connector 2 to release the prohibition on movement of CPA member 12.
[0039] In addition, in this embodiment, the pair of CPA side protrusions 123 have a CPA front side inclined surface 123a formed on the front side of each CPA side protrusion 123 in the movement direction D12. On the other hand, the pair of housing side protrusions 113 have a housing side inclined surface 113a formed on the rear side of each housing side protrusion 113 in the movement direction D12. According to this configuration, when the CPA member 12 is attached to the housing in a provisionally locked state, first, the CPA front side inclined surface 123a of the CPA side protrusion 123 faces the housing side inclined surface 113a of the housing side protrusion 113. Thereafter, the CPA front side inclined surface 123a slides against the housing side inclined surface 113a, so that the CPA side protrusion 123 smoothly rides up on the housing side protrusion 113 and an abutting state between the two is established, so that the CPA member 12 can be attached with good workability.
[0040] In addition, in this embodiment, the pair of CPA side projections 123 are formed with the CPA rear side inclined surface 123b on the rear side of the movement direction D12 of each CPA side projection 123. According to this configuration, when the CPA member 12 in the fully locked state is returned to the provisionally locked state prior to the disengagement of the engagement, the CPA rear side inclined surface 123b rubs against the housing side projection 113. This rubbing causes the CPA side projection 123 to smoothly ride up on the housing side projection 113 and establish an abutment state between the two. At this time, since the housing side projection 113 is not provided with an inclined surface corresponding to the CPA rear side inclined surface 123b, a situation in which the CPA member 12 in the fully locked state unintentionally returns to the provisionally locked state is suppressed, and the stability of the fully locked state is ensured. Thus, according to the above configuration, while ensuring the stability of the fully locked state, when the CPA member 12 in the fully locked state is returned to the provisionally locked state prior to the disengagement of the engagement, the CPA member 12 can be moved with good operability.
[0041] The above-described embodiment is merely a representative example of the connector, and the connector is not limited to this embodiment but can be modified in various ways.
[0042] For example, in the above-described embodiment, the connector 1 used as an end connector of a wire harness mounted on a vehicle, etc. is illustrated as an example of a connector. However, the connector is not limited to this, and there is no restriction on the specific application of the connector.
[0043] In the above-described embodiment, the housing 11a having a rectangular block-like appearance is illustrated as an example of the housing, but the housing is not limited to this, and the specific exterior shape and the like may be any shape.
[0044] In the above-described embodiment, as an example of a pair of CPA side protrusions, a pair of CPA side protrusions 123 provided adjacent to the main release receiving portion 122b formed to protrude from the CPA arm 122 is exemplified. However, the pair of CPA side protrusions is not limited to this, and the installation position can be set appropriately. However, as described above, by providing the CPA side protrusions 123 adjacent to the main release receiving portion 122b, unintended deflection of the CPA arm 122 when subjected to an external force can be effectively suppressed.
[0045] Also, in the above-described embodiment, as an example of a CPA arm, a CPA arm 122 in which the length L12 of the portion from the pair of CPA side protrusions 123 to the free end side is longer than the length L11 of the portion from the pair of CPA side protrusions 123 to the fixed end side is exemplified. However, the CPA arm is not limited to this, and may be formed so that the free end side is shorter, as opposed to the above. However, as described above, by lengthening the free end side, the free end side of the CPA arm 122 can be effectively bent to release the prohibition on movement of the CPA member 12.
[0046] In the above-described embodiment, the CPA side protrusion 123 on which the CPA front side inclined surface 123a is formed and the housing side protrusion 113 on which the housing side inclined surface 113a is formed are exemplified as an example of the CPA side protrusion and the housing side protrusion. However, the CPA side protrusion and the housing side protrusion are not limited to this, and the above-described inclined surface may not be provided on either the CPA side protrusion or the housing side protrusion. However, as described above, by providing the CPA front side inclined surface 123a on the CPA side protrusion 123 and providing the housing side inclined surface 113a on the housing side protrusion 113, the CPA member 12 can be attached with good workability.
[0047] In the above-described embodiment, the CPA side protrusion 123 having the CPA rear side inclined surface 123b formed thereon is illustrated as an example of the CPA side protrusion. However, the CPA side protrusion is not limited to this, and any inclined surface may not be provided on the rear side in the movement direction. However, as described above, by providing the CPA rear side inclined surface 123b, the CPA member 12 can be moved with good operability when returning the CPA member 12 from the fully locked state to the provisionally locked state.

Claims
1. a connector body having connector terminals accommodated in a cavity of a housing; a CPA member that is attached to the housing in a provisionally locked state, that is prohibited from moving in a direction along the mating direction before the connector body is mated with the mating connector, and that, when the prohibition is released upon mating, moves in the direction along the mating direction to transition to a fully locked state, thereby ensuring the mating; The CPA member is a CPA body that is provisionally engaged with the housing and that is operated to transition to the final engagement state at a rear side in the moving direction; a CPA arm which is a cantilever extending from the CPA body in the movement direction, and which abuts against the housing at a free end thereof before the engagement to prohibit the movement, and which is fully engaged with the housing at the end thereof when the engagement is released; A pair of CPA side protrusions protruding in the width direction of the CPA arm from intermediate positions between the fixed end side and the free end side on each of a pair of side edges of the CPA arm, The housing comprises: a housing body in which the cavity is provided; a CPA receiving portion that defines a CPA receiving space for receiving the CPA member with a CPA moving surface, on which the CPA member moves, as a bottom surface of the outer peripheral surface of the housing body, and in which the CPA body is provisionally locked in the provisionally locked state and in which the end of the CPA arm is fully locked in the fully locked state; The connector is characterized in that it is provided with a pair of housing side protrusions formed at a position on the CPA moving surface that does not overlap with the CPA arm when viewed in a plane relative to the CPA moving surface, abuts against the pair of CPA side protrusions in the temporary engagement state, and is disengaged from the pair of CPA side protrusions in the final engagement state.
2. The CPA arm has a main lock release receiving portion formed at a midpoint between the fixed end side and the free end side on an outer surface opposite to the CPA moving surface, the main lock release receiving portion receiving a main lock release operation that bends the CPA arm to release the main lock of the end when in the main lock state, 2. The connector according to claim 1, wherein the pair of CPA side projections protrude from positions adjacent to the full lock release receiving portion on each of the pair of side edges.
3. The connector described in claim 1, characterized in that the CPA arm is formed so that the length of the portion from the pair of CPA side protrusions to the free end side is longer than the length of the portion from the pair of CPA side protrusions to the fixed end side.
4. The pair of CPA side protrusions are formed with a CPA front side inclined surface on a front side of each CPA side protrusion in the moving direction, the CPA front side inclined surface being inclined so that the distance from the CPA moving surface gradually increases as the CPA side protrusion moves in the moving direction, The connector described in claim 1, characterized in that the pair of housing side protrusions have a housing side inclined surface formed on the rear side of each housing side protrusion in the movement direction, which is inclined so that the protruding height from the CPA movement surface gradually increases as the protrusion proceeds in the movement direction.
5. The connector described in claim 4, characterized in that the pair of CPA side protrusions have a CPA rear side inclined surface formed on the rear side of each CPA side protrusion in the movement direction, the CPA rear side inclined surface being gradually spaced from the CPA movement surface as it progresses toward the movement direction.
