Abstract

PROBLEM TO BE SOLVED: To provide a low insertion force type connector capable of preventing a semi-fitting state.SOLUTION: A low insertion force type connector 1 comprises a housing 2, a cam shaft 8, a cam 7, a locking member 48, and an idling stopper 50. The housing 2 holds contacts 28, 30, and is fitted with a mating connector. The cam shaft 8 is rotatably held by the housing 2, and operated to rotate. The cam 7 flexes each of the contacts 28, 30 together with rotation of the cam shaft 8, and makes them into contact of a terminal of the mating connector. The locking member 48 is locked with the mating connector together with rotation of the cam shaft 8, so as to prevent the mating connector from being detached from the housing. The idling stopper 50 is supported by the housing 2 movably between a rotation blocking position for blocking rotation of the cam shaft 8, and a rotation allowing position for allowing rotation of the cam shaft, and is pressed by the mating connector fitted with the housing, so as to move from the rotation blocking position to the rotation allowing position.

Description

  The present invention relates to a low insertion force type connector.

  As a connector having a large number of contacts, a low insertion force type connector called a LIF (low insertion force) or ZIF (zero insertion force) connector with a reduced insertion force when mating with a mating connector is known. Yes.

  Patent Document 1 discloses a low insertion force type connector. This low insertion force type connector includes a contact, a camshaft, and locking means. The camshaft rotates to urge the contact toward the counterpart contact. The locking means is arranged with the same shaft as the camshaft, and engages with the protrusion of the mating connector to lock the connector and the mating connector. When this low insertion force type connector is inserted into the mating connector, resistance due to contact between the contact and the mating contact is reduced. When the camshaft is rotated by operation in the inserted state, the contact is urged by the mating contact, and the locking means engages with the projection of the mating connector to be locked.

JP 2002-170642 A

  However, the camshaft and the locking means of the low insertion force connector shown in Patent Document 1 can be rotated to a position corresponding to the locked state by operation even when the low insertion force connector is not inserted into the mating connector. Therefore, a half-fitted state may occur.

  An object of the present invention is to solve the above-mentioned problems and to provide a low insertion force type connector capable of preventing the occurrence of a half-fitted state.

The low insertion force type connector of the present invention that achieves the above object is
A plurality of contacts arranged corresponding to a plurality of terminals of the mating connector;
A housing for holding the contact and fitting with the mating connector;
A camshaft rotatably held in the housing and rotated by operation;
A cam provided on the camshaft that bends each of the contacts as the camshaft rotates to contact each of the terminals of the mating connector fitted in the housing;
A locking member provided on the camshaft that locks the mating connector with respect to the housing by locking with the mating connector fitted to the housing as the camshaft rotates,
The housing is movably supported between a rotation prevention position for preventing the rotation of the cam shaft and a rotation allowable position for allowing the rotation of the cam shaft, and is pushed by the mating connector fitted to the housing. And an idling stopper that moves from the rotation prevention position to the rotation permissible position.

  In the low insertion force type connector of the present invention, rotation of the camshaft is permitted when the mating connector pushes the idling stopper to the rotation allowable position. Then, as the camshaft is rotated by operation, the lock member is engaged with the mating connector to prevent the mating connector from being removed from the housing. When the mating connector does not press the idle stopper, the rotation of the cam shaft is prevented. In this case, the cam shaft does not rotate even if the rotation is performed, and the lock member does not engage the mating connector. Therefore, it is possible to prevent a half-fitted state even though the camshaft is operated and rotated to the retaining state.

Here, in the low insertion force type connector of the present invention,
The camshaft has a rotation preventing portion having a non-circular cross section;
It is preferable that the idling stopper prevents rotation of the camshaft by sandwiching a short diameter portion of the rotation prevention portion from both sides at the rotation prevention position.

  By adopting a structure in which the short diameter portion of the rotation preventing portion of the cam shaft is sandwiched from both sides, the rotation of the cam shaft can be reliably prevented and the idling stopper can be miniaturized.

  In the low insertion force connector according to the present invention, the idling stopper includes a pair of stopper blocks disposed at positions corresponding to both end portions of the mating connector in the extending direction of the cam shaft. It is preferable.

  By arranging the pair of stopper blocks at positions corresponding to both end portions of the mating connector, the cam shaft does not rotate even when the mating connector is half-fitted in an inclined posture. Therefore, when the camshaft is operated and rotated to the retaining state, it is possible to prevent a situation where the camshaft is actually in a semi-fitted state with an inclined posture.

  As described above, according to the present invention, a low insertion force connector capable of preventing the half-fitted state is realized.

  The low insertion force type connector 1 (hereinafter simply referred to as a connector 1) includes a housing 2, a contact assembly 6, a drive shaft 8, a lever 10, a cover member 12, and an idling stopper 50.

  The housing 2 has a rectangular parallelepiped shape having a recess 4 (see FIGS. 4 and 5). The housing 2 is made of a metal material for electromagnetic shielding. Two rectangular openings 16 (see FIG. 4) extending in the longitudinal direction (axial direction Y) of the housing 2 are formed in parallel at the bottom of the housing 2. A bottom wall 14 is formed between the two openings 16 and 16. Support walls 17 lower than the height of the housing 2 are formed at both ends in the longitudinal direction (axial direction Y) of the opening 16 (see FIG. 5). In FIG. 5, the support wall 17 disposed on one of the two pairs of support walls 17 in the axial direction Y is shown. A separation wall 18 (see FIG. 4) that connects the two support walls 17 extends in the axial direction Y on the bottom wall 14. The separation wall 18 is continuous with the bottom wall 14.

  A pair of escape grooves 20 and a pair of curved support grooves 22 are formed adjacent to both sides in the axial direction Y of the escape grooves 20 on the upper surfaces of the pair of support walls 17. FIG. 5 shows one escape groove 20 out of a pair of escape grooves 20 provided on one support wall 17 and support grooves 22 adjacent to both sides of the escape groove 20.

  In the center of the upper surface of the support wall 17, a female screw 23 (see FIG. 12) is formed between the two escape grooves 20 toward the bottom wall 14. A space 24 is formed outside the both support walls 17, that is, inside the end walls 26 a and 26 b of the housing 2. Further, a notch 5 extending downward from the upper edge 4a of the recess 4 is formed in the end wall 26b.

  The contact assembly 6 is disposed in the recess 4 of the housing 2. The contact assembly 6 includes two types of contacts 28 and 30 and a base member 26. The contacts 28 and 30 are formed by punching and bending a metal plate having spring properties. The contacts 28 and 30 have a main body 34 and a tine 32 that extends downward from the main body 34 and is attached to a substrate (not shown). The two types of contacts 28 and 30 have different shapes. The contacts 28 and 30 are formed such that the main body 34 bulges outward. The contacts 28 and 30 are arranged corresponding to the contacts 104 of the mating connector 100 (see FIGS. 7 to 9). The contacts 28 and 30 are held by insert molding on two insulating base members 26 molded of resin. In each base member 26, two pairs of two rows each including a row of contacts 28 arranged in the axial direction Y and a row of contacts 30 arranged in the axial direction Y are arranged. In the present embodiment, the base member 26 is configured by arranging one row of contacts 28 and 30 on each of the two divided members and combining the base members 26. Each base member 26 is attached to the opening 16 of the housing 2.

  As shown in FIG. 4, the distal end portion of the curved main body 34 of each contact 28, 30 of the contact assembly 6 has a contact portion 36 that converges and extends inward. The tip of the contact portion 36 has a locking end portion 38 that is further bent inward. The contact assembly 6 is attached to the housing 2 by placing the base member 26 in the opening 16. At this time, the tine 32 protrudes downward from the bottom surface of the base member 26 as shown in FIGS.

  Next, the drive shaft 8 and the lever 10 that drive the contact assembly 6 will be described. The drive shaft 8 extends in the axial direction Y. Two drive shafts 8 are provided corresponding to the two pairs of contact rows, and are arranged between the row of contacts 28 and the row of contacts 30. The drive shaft 8 is formed of a metal material such as stainless steel, and extends linearly longer than the row of contacts 28 and 30. The drive shaft 8 has a circular section and a quadrangular section. A biasing cam 7 is provided on the drive shaft 8 at a position facing the contacts 28 and 30. The urging cam 7 is a member made of an insulating resin formed around the drive shaft 8 by insert molding. The urging cam 7 has a substantially parallelogram shape whose cross-sectional shape is chamfered as shown in FIG. As shown in FIG. 4, the urging cam 7 is usually arranged with the minor axis facing sideways and the diagonal having the major axis inclined diagonally.

  A separation cam 44 is formed on one end of the drive shaft 8 in the axial direction Y of the urging cam 7 via a reduced diameter portion 42, and the other is provided on the rotation blocking portion via a reduced diameter portion 42. 49 is provided. The separation cam 44 is a plate cam, and when the biasing cam 7 is in the posture shown in FIG. 4, the stop portion 44a (see FIG. 15) farthest from the axis is arranged upward, that is, toward the mating connector. Yes. The drive shaft 8 corresponds to an example of a cam shaft according to the present invention, and the biasing cam 7 corresponds to an example of a cam according to the present invention.

  The rotation preventing portion 49 is a portion where the cross section of the drive shaft 8 is a non-circular shape. More specifically, the cross section of the rotation preventing portion 49 has a shape obtained by cutting two opposite portions of a circle with parallel lines. In each of the two urging cams 7, a separation cam 44 is disposed at one end portion, and a rotation blocking portion 49 is disposed at the other end portion. In the two urging cams 7 arranged substantially in parallel, the separation cams 44 and the rotation blocking portions 49 are alternately arranged.

  A lock member 48 is formed on the drive shaft 8 on the further outer side of the rotation preventing portion 49 when viewed from the biasing cam 7. The lock member 48 is also formed on the outside of the separation cam 44 via another reduced diameter portion 46. The lock member 48 is a member that engages with the protrusion 112 (see FIG. 7) of the mating connector 100, and has a key shape. More specifically, the lock member 48 includes a flat plate portion 48 a that rotates together with the biasing cam 7, and a claw 48 b that extends from the flat plate portion 48 a and has a shape that substantially follows a rotating arc around the drive shaft 8. . The claw 48b is normally in a state where the tip of the claw 48b faces upward between the two drive shafts 8. A gear 54 is formed outside the lock member 48 adjacent to the lock member 48. That is, the gear 54 is formed at both ends of each drive shaft 8 and is formed in a fan shape so that the two drive shafts 8 provided on the two drive shafts 8 are combined with each other. The teeth 56 of the gear 54 are formed in a sectoral arc surface.

  One end of the two drive shafts 8 extends to the outside of the housing 2. The lever 10 is connected to a portion extending to the outside. The drive shaft 8 and the lever 10 function as an operation unit. In the present embodiment, the separation cam 44 is formed integrally with the drive shaft 8, but may be a separate body. The lock member 48 is attached to the end of the drive shaft 8 as a separate member, but may be formed integrally with the drive shaft 8.

  In a state where the drive shaft 8 is mounted in the housing 2, the reduced diameter portions 42 and 46 of each drive shaft 8 are placed in the support groove 22, and the separation cam 44 is accommodated in the escape groove 20. That is, the drive shaft 8 is rotatably held by the housing 2. In this state, the gears 54 are combined with each other, and when the lever 10 is rotated, the other drive shaft 8 is also rotated in conjunction with the one drive shaft 8 to which the lever 10 is coupled. The directions in which the two drive shafts 8 rotate are opposite to each other.

[Idling stopper]
The idling stopper 50 is disposed in the recess 4 of the housing 2. More specifically, the idling stopper 50 includes a pair of stopper blocks 51 disposed in the space 24 outside the both support walls 17 and a pair of springs 52 that respectively bias the stopper blocks 51. The pair of stopper blocks 51 are disposed at positions corresponding to both end portions in the longitudinal direction (axial direction Y) of the mating connector 100 (see FIG. 7) to be fitted to the connector 1. More specifically, the stopper block 51 is disposed at the end of the pair of biasing cams 7 on the side where the separation cam 44 is not disposed, in both ends in the axial direction Y.

  FIG. 6 is a perspective view of the stopper block. Part (A) of FIG. 6 is a perspective view seen from above with substantially the same posture as shown in FIG. 5, and Part (B) is a perspective view showing a vertically inverted posture.

  The stopper block 51 shown in FIG. 6 has a rotation prevention part 51a, a release protrusion 51b, and a spring support protrusion 51c. The stopper block 51 is made of a metal material. That is, the rotation preventing part 51a, the release protrusion 51b, and the spring support protrusion 51c are integrally formed. The rotation prevention unit 51a has a pair of parallel wall surfaces 51d that face each other and are parallel to each other. More specifically, the rotation preventing portion 51a is formed with a U-shaped notch that opens upward. The distance between the pair of wall surfaces 51d is substantially equal to the width of the short diameter portion of the rotation preventing portion 49 (see FIG. 12) of the drive shaft 8. The release protrusion 51b is a protrusion that protrudes upward from the rotation preventing portion 51a. The spring support protrusion 51c is a protrusion that protrudes in the opposite direction from the release protrusion 51b from the rotation blocking portion 51a.

  With reference to FIG. 5 again, the description of the idling stopper 50 will be continued.

  The stopper block 51 is disposed in the space 24 so as to be movable in the vertical direction. The stopper block 51 is supported by the base member 26 via a spring 52. The spring 52 is a compression coil spring. One end of the spring 52 is supported by a groove 26 d provided in the base member 26, and the other end of the spring 52 is supported by a spring support protrusion 51 c of the stopper block 51. The stopper block 51 is biased upward by the spring 52, that is, toward the mating connector 100 that fits with the connector 1.

[Cover member]
The cover member 12 will be described with reference to FIGS. 1 to 5 again. The cover member 12 is a substantially rectangular member formed of an insulating resin material. The cover member 12 has two rows of holding portions 60 extending in the longitudinal direction (axial direction Y) of the cover member 12 corresponding to the rows of the contacts 28 and 30 on the main surface 62 thereof. Each holding portion 60 protrudes from the main surface 62 and is formed integrally with the cover member 12. On the both sides of the holding portion 60, as best shown in FIG. 5, a number of vertically extending slots 64 are provided at positions corresponding to the contact portions 36 of the contacts 28 and 30 in the longitudinal direction (axial direction) of the holding portion 60. Y). Through these slots 64, the contact portions 36 of the contacts 28 and 30 are exposed to the outside and come into contact with the counterpart terminal.

  As shown in FIG. 4, a space 68 divided by the isolation wall 66 is formed inside the holding portion 60. A locking recess 70 is formed in the vicinity of the upper portion of the space 68. In addition, a hole 72 (see FIG. 5) is provided at the center of the width of the cover member 12 at both ends of the holding portion 60. Adjacent to the hole 72, elongated rectangular openings 74 are formed on both sides of the cover member 12 in the width direction. Of the four openings 74 provided on both sides in the width direction and the axial direction Y, the separation cam 44 is disposed in the two openings 74. In the remaining two openings 74, release protrusions 51b of the stopper block 51 are arranged. Furthermore, an opening 80 extending in the width direction of the cover member 12 is formed in the vicinity of both ends of the cover member 12 outside the opening 74. A lock member 48 is disposed in the opening 80. Both ends of the cover member 12 are connected to the connecting portion 82.

  In order to attach the cover member 12 to the housing 2, the cover member 12 is disposed in the recess 4 of the housing 2, the bolt 13 (see FIG. 5) is inserted into the hole 72, and further screwed into the female screw 23 of the housing 2. (See FIG. 12). As shown in FIG. 4, the locking end portions 38 of the contacts 28 and 30 are locked in the locking recesses 70 of the cover member 12. As a result, the contacts 28 and 30 can be bent in the lateral direction, that is, the direction intersecting the fitting direction, between the base member 26 and the locking recess 70. The drive shaft 8 is supported by the above-described support groove 22 so that the diameter-reduced portions 42 and 46 of the drive shaft 8 are rotatable.

  The lever 10 is connected to one portion of the drive shaft 8 that protrudes outward from the housing 2. Therefore, the lever 10 can be operated outside the housing 2. Before the connectors are fitted together, the drive shaft 8 and the biasing cam 7 are in the positions shown in FIG. That is, the main body 34 and the contact portion 36 of the contacts 28 and 30 are in the most inwardly located state.

[Mating connector]
Next, the mating connector 100 fitted to the connector 1 will be described with reference to FIGS. 7 is a front view of the mating connector 100, and FIG. 8 is a bottom view of the mating connector of FIG. FIG. 9 is a side view of the mating connector of FIG.

  The mating connector 100 includes a housing 102, a terminal 104, and a fitting portion 106. As with the housing 2, the housing 102 is also made of a metal material for electromagnetic shielding. The fitting portion 106 is a member formed of an insulating resin material, and is fixed to the housing 102. The fitting portion 106 holds the terminal 104. The combination of the housing 102 and the fitting portion 106 corresponds to an example of the housing of the mating connector according to the present invention.

  At both ends of the fitting portion 106 to be combined with the connector 1, stepped portions 108 having a shape complementary to the connecting portion 82 are formed. Protrusions 112 extending in the longitudinal direction (axial direction Y) of the housing 102 are provided on the outward end surface 110 of each step portion 108 so as to correspond to the two drive shafts 8 described above. A tine 114 of the terminal 104 protrudes from the rear of the mating connector 100, that is, the upper side in FIG. Two fitting recesses 116 for receiving the holding portion 60 (see FIG. 5) are formed in the fitting portion 106 in parallel corresponding to the holding portion 60 (see FIG. 8). As shown in FIG. 9, the tines 114 of the mating connector 100 are arranged in two rows, and two pairs thereof are arranged.

[State during connector mating]
10-12 is a figure which shows the state in the middle of a connector fitting with a mating connector. FIG. 10 is a front view, and FIG. 11 is a side view. 12 is a cross-sectional view showing a cross section taken along line 12-12 of FIG.

  In order to engage the mating connector 100 with the connector 1, first, the mating portion 106 of the mating connector 100 is inserted into the recess 4 (see FIG. 2) of the housing 2 of the connector 1. As shown in FIG. 12, the stopper block 51 is biased upward by a spring 52. In a state where the mating connector 100 and the connector 1 are not fitted, the release protrusion 51 b of the stopper block 51 projects upward from the cover member 12, that is, toward the mating connector 100. Further, in this state, the rotation blocking portion 51a of the stopper block 51 sandwiches the short diameter portion of the rotation blocking portion 49 of the drive shaft 8 (see FIG. 5) from both sides. Therefore, in this state, the rotation of the drive shaft 8 is prevented, and the drive shaft 8 does not rotate even when the lever 10 is operated. The position of the stopper block 51 shown in FIG. 12 is referred to as a rotation prevention position. When the mating connector 100 is further pushed into the connector 1 from the state shown in FIGS. 10 to 12, the fitting portion 106 of the mating connector 100 and the housing 2 of the connector 1 are fitted.

[Connector mating condition]
Next, a state in which the connector 1 and the mating connector 100 are fitted will be described with reference to FIGS. 13 is a front view showing a connector assembly (hereinafter simply referred to as an assembly) 190 in which the connector 1 and the mating counterpart connector 100 are fitted, and FIG. 14 is a side view of the assembly 190 in FIG. . 15 is a cross-sectional view of the assembly 190 taken along the line 15-15 in FIG. 14, FIG. 16 is a cross-sectional view of the assembly 190 taken along the line 16-16 in FIG. 13, and FIG. It is sectional drawing of the assembly 190 which follows the 17-17 line | wire of FIG.

  13 and 14 show an initial state in which the connectors are fitted, that is, a state immediately before the mating connector 100 and the connector 1 are completely fitted. Therefore, both the connectors 1 and 100 are not completely fitted. The lever 10 is inclined to the left as shown in FIG. FIG. 14 clearly shows that the key protrusion 120 of the mating connector 100 has entered the notch 5 of the connector 1. The connectors 1 and 100 can be fitted only in the direction in which the key protrusion 120 and the notch 5 are assembled.

  Next, the positional relationship between the mating connector 100 and the connector 1 in this state, that is, the state immediately before complete fitting will be described. As shown in FIG. 15, when the mating connector 100 is inserted into the connector 1, the mating surface 122 of the mating connector 100 abuts against the stop portion 44 a of the separation cam 44 at the abutting position. The operation is stopped with a gap left between the member 12 and the member 12. A gap G can be visually recognized between the connector 1 and the mating connector 100 from the outside of the assembly 190. As shown in FIG. 16, the cross-sectional shape of the portion of the drive shaft 8 that penetrates the lock member 48 is a quadrangular shape.

  Further, in a state where the mating connector 100 and the connector 1 are fitted (a state just before complete mating), the stopper block 51 has its release projection 51b pressed against the mating surface 122 of the mating connector 100, so that FIG. It moves from the rotation prevention position shown to the lower rotation allowable position shown in FIG. At the rotation allowable position, the rotation blocking portion 51 a of the stopper block 51 is disengaged from the rotation blocking portion 49 of the drive shaft 8. Therefore, when the lever 10 (see FIG. 14) is operated, the drive shaft 8 can rotate. When the stopper block 51 moves to the rotation allowable position, the spring 52 is further compressed (elastically deformed).

  Immediately before complete fitting, the biasing cam 7 of the drive shaft 8 and the contacts 28 and 30 are in the positional relationship shown in FIG. That is, the contacts 28 and 30 are displaced inwardly because the major axis of the biasing cam 7 extends obliquely. Therefore, the contact portion 36 of the contacts 28 and 30 is also not located in the slot 64 but is positioned in the slot 64. On the other hand, the contact portion 126 at the tip of the terminal of the mating connector 100 to be inserted is in a state of low contact pressure, which is in slight contact with the contact portion 36 of the contacts 28 and 30. Therefore, the insertion force required at this time can be reduced. At this time, no contact pressure may be generated. In other words, in the connectors, the terminal 104 and the contacts 28 and 30 may be fitted in a non-contact state.

  Next, with reference to FIG. 16, the position of the lock member 48 immediately before complete fitting will be described. The lock members 48 adjacent to each other overlap each other at the claw 48b, and the tip of the claw 48b is disposed obliquely upward. Accordingly, the engagement space 55 formed between the flat plate portion 48a and the claw 48b of the lock member 48 opens obliquely upward. In a state where the rotation blocking portion 51a of the stopper block 51 shown in FIG. 15 is disengaged from the rotation blocking portion 49 of the drive shaft 8, when the protrusion 112 of the mating connector 100 shown in FIG. It is in a position that can be accommodated in the engagement space 55. The cross-sectional shape of the portion of the drive shaft 8 that penetrates the lock member 48 is a quadrangular shape. A member having a circular cross section provided between the drive shaft 8 and the lock member 48 is a spacer 59 for shifting the position of the two lock members 48 in the direction orthogonal to the paper surface. The drive shaft 8 may be formed in the same cross-sectional shape from the gear 54 at one end to the gear 54 at the other end. The cross-sectional shape of the drive shaft 8 may be a shape other than a quadrangle such as a triangle or a hexagon.

[Fully mated state]
Next, the state when the connectors are completely fitted together will be described. 18 is a side view showing a fully fitted state in which the lever is operated from the state shown in FIG. FIG. 19 is a cross-sectional view of the assembly 190 similar to FIG. 15 in a fully fitted state along the line 15-15 in FIG. 20 is a cross-sectional view of assembly 190 similar to FIG. 16 in a fully engaged condition. FIG. 21 is a cross-sectional view of the assembly 190 similar to FIG. Hereinafter, a description will be given with reference to FIGS.

  As shown in FIG. 19, the rotation blocking portion 51 a of the stopper block 51 is disengaged from the rotation blocking portion 49 of the drive shaft 8. Therefore, the lever 10 can be raised to the posture shown in FIG. 18 by an operation. At this time, the drive shaft 8 rotates about 60 °.

  When the lever 10 is rotated, the separation cam 44 is also rotated in conjunction with the drive shaft 8. And the stop part 44a of the separation cam 44 which contact | abutted with the fitting surface 122 of the other party connector 100 leaves | separates from the fitting surface 122, and faces outward. That is, the separation cam 44 is in a non-contact position. Therefore, the mating connector 100 can further enter the connector 1.

  Next, the relationship between the contacts 28 and 30 and the terminal 104 will be described with reference to FIG. As the urging cam 7 provided on the drive shaft 8 rotates by about 60 °, the major diameter of the urging cam 7 becomes sideways, and the contact portions 36 of the contacts 28 and 30 are bent outward. The contact portion 36 is biased toward the contact portion 126 of the terminal of the mating connector 100 and comes into contact with the contact portion 126. As a result, the terminal 104 and the contacts 28 and 30 are electrically connected.

  Next, locking (preventing) of connectors will be described with reference to FIG. When the protrusion 112 of the mating connector 100 starts to enter the engagement space 55 of the lock member 48 as the drive shaft 8 rotates, the engagement becomes an inner side of the claw 48 b, that is, a side edge outside the engagement space 55. The cam surface 57 and the protrusion 112 are engaged. The engagement cam surface 57 is formed so as to approach the center of the flat plate portion 48 a, that is, the axis of the drive shaft 8 as it becomes inward of the slot 55. That is, the engagement cam surface 57 is formed gradually. Accordingly, the protrusion 112 is pulled toward the connector 1 as the lock member 48 is rotated. In other words, the mating connector 100 is pulled into the connector 1 and the terminals 104 and the contacts 28 and 30 (see FIG. 21) are wiped, whereby the connectors are locked in the fully fitted position. If the lever 10 can be smoothly rotated and locked, it can be confirmed that the connectors are completely fitted. Further, since the gap G between the connectors shown in FIG. 15 is eliminated, it can be confirmed from the appearance that the connectors are completely fitted together, and the housings 2 and 102 (see FIG. 18) are electrically interconnected. .

  According to the connector 1 of the present embodiment, when the mating connector 100 is not inserted until the mated state shown in FIG. 15 (immediately before complete mating), that is, in the half-fitted state shown in FIG. Since the portion 51a sandwiches the short diameter portion of the rotation blocking portion 49 of the drive shaft 8 from both sides, the rotation of the drive shaft 8 is blocked. The lever 10 can be rotated when the mating connector 100 is inserted to the fitted state shown in FIG. Therefore, a situation in which the lever 10 remains in a semi-fitted state despite the rotation of the lever 10 is prevented. Further, it is easily determined by the response of the lever 10 that the half-fitted state cannot be secured. Further, the two stopper blocks 51 included in the idling stopper 50 are arranged at positions corresponding to both end portions in the longitudinal direction (axial direction Y) of the mating connector 100 (see FIG. 7). Therefore, even when the mating connector 100 is tilted and one stopper block 51 is half-fitted, the drive shaft 8 does not rotate. Therefore, occurrence of a semi-fitted state in which the mating connector 100 is inclined is also prevented.

  Although the present invention has been described in detail above, the contact urging means may have other configurations. That is, the contact urging means is disposed outside the contact row, and the contact is formed in a shape bulging outward in advance. The contact may be bent inward only when the contact is urged inward from the outside by the contact urging means. In this case, when the connector is mated, the contact urging means works and the contact is bent inward, and after the mating, the contact urging means is released and the contact returns to the outside so that the connectors are connected to each other. The electrical connection is made.

  Further, as an example of the idling stopper, a configuration of a stopper block 51 that sandwiches the short diameter portion of the rotation blocking portion 49 of the drive shaft 8 from both sides is shown. However, the idling stopper is not limited to this, and for example, the idling stopper may prevent rotation by suppressing a protrusion provided on the cam shaft. However, by adopting a structure in which the short-diameter portion of the rotation preventing portion 49 of the drive shaft 8 is sandwiched from both sides, it is possible to reliably prevent rotation and downsize the idling stopper.

  Further, the number of stopper blocks may be three or four.

  Further, the housing 2 may be made of resin when the purpose is not electromagnetic shielding.

  Further, the structure is not limited to the structure in which the mating connector is inserted into the connector, and a structure in which the connector is inserted into the mating connector may be employed.
