Description

The present disclosure relates to connectors.

Conventionally, a connector such as a board-to-board connector has been used to electrically connect a pair of parallel circuit boards to each other. Such connectors are attached to each of the facing surfaces of a pair of circuit boards so that they engage with each other to conduct electricity. Further, a technique has been proposed in which reinforcing metal fittings attached to both ends function as lock members to maintain a fitted state with a mating connector (see, for example, Patent Document 1).

FIG. 7 is a perspective view showing a conventional connector.

In the figure, 811 is a first housing as a housing of a first connector mounted on a first circuit board (not shown), and 911 is a housing of a second connector mounted on a second circuit board (not shown). There are two housings. By fitting the first connector and the second connector, the first circuit board and the second circuit board are electrically connected. In the figure, the fitting surface of the first housing 811 faces upward, and the fitting surface of the second housing 911 faces downward. In this posture, the first connector is relative to the second connector. Can be fitted in close proximity to.

The first housing 811 includes a pair of side wall portions 814 extending in the longitudinal direction and a pair of fitting guide portions 821 connected to both ends in the longitudinal direction of the side wall portions 814. A fitting recess 822 is formed in each fitting guide portion 821. A plurality of first terminals 861 are attached to the side wall portion 814, and a first reinforcing metal fitting 851 is attached to the fitting guide portion 821.

Further, the second housing 911 includes a pair of fitting protrusions 922 formed at both ends in the longitudinal direction. A plurality of second terminals 961 are attached to the second housing 911, and a second reinforcing metal fitting 951 is attached to the fitting convex portion 922.

When the first connector and the second connector are fitted, the corresponding first terminal 861 and the second terminal 961 come into contact with each other. As a result, the first circuit board and the second circuit board are electrically connected. Further, the fitting convex portion 922 enters the fitting concave portion 822 of the fitting guide portion 821. Then, the engaging projection 858 of the first reinforcing metal fitting 851 formed so as to project into the fitting recess 822 engages with the side portion of the second reinforcing metal fitting 951. As a result, the first connector and the second connector are locked, and the fitted state thereof is maintained.

However, in the conventional connector, the first housing 811 or the second housing 911 may be damaged or damaged during the fitting operation. When mating the first connector attached to the first circuit board and the second connector attached to the second circuit board, depending on the working conditions, the operator may use the fitting surface of the first housing 811 and the second housing 911. It may not be possible to see the fitting surface of the fitting surface, and the fitting work may have to be performed by fumbling. In particular, in recent years, as the size and height of the board-to-board connector have been reduced, it is difficult for the operator to visually check the fitting surface of the first housing 811 and the fitting surface of the second housing 911.

In this case, the operator adjusts the position of the second housing 911 with respect to the first housing 811 while sliding the fitting surface of the first housing 811 and the fitting surface of the second housing 911 by fumbling. Then, the fitting convex portion 922 of the second housing 911 is inserted into the fitting concave portion 822 of the first housing 811.

Therefore, a force in the fitting direction may be applied to the first housing 811 and the second housing 911 in a state where the alignment between the first housing 811 and the second housing 911 is not completed. In this case, a part of the fitting surface of the first housing 811 or a part of the fitting surface of the second housing 911 may be damaged or damaged due to a large pressing force. In particular, since the fitting guide portions 821 formed at both ends of the first housing 811 in the longitudinal direction are relatively thin, for example, when the ends in the longitudinal direction of the second housing 911 abut diagonally, the fitting guide portions 821 are easily damaged. Resulting in.

Further, by connecting the first reinforcing metal fittings 851 and the second reinforcing metal fittings 951 to the power supply lines of the first circuit board and the second circuit board, the first reinforcing metal fittings 851 and the second reinforcing metal fittings 951 are connected to the electric circuit. Although it may be used as a member, the engaging projection 858 of the first reinforcing metal fitting 851 does not have sufficient flexibility. Therefore, when the vibration or impact generated when the first circuit board and the electronic device on which the second circuit board is mounted is dropped or receives an external force, the first reinforcing metal fitting 851 and the second reinforcing metal fitting 851 and the second reinforcement are transmitted. It is conceivable that the contact with the metal fitting 951 cannot be maintained and sufficient continuity cannot be ensured as a power supply line.

Here, the problem of the conventional connector is solved, and the fitting guide portion of the connector body is not damaged or damaged during the fitting work, and the reinforcing metal fitting and the mating reinforcing metal fitting are used. It is an object of the present invention to provide a highly reliable connector capable of reliably maintaining a conductive state and reliably maintaining a mating with a mating connector.

Therefore, the connector is a connector including a connector main body, a terminal loaded in the connector main body, and a reinforcing metal fitting loaded in the connector main body, and the connector main body is a convex extending in the longitudinal direction. A convex portion inserted into a concave portion extending in the longitudinal direction of the mating connector body of the mating connector, and a fitting guide portion formed at both ends in the longitudinal direction, which is the length of the mating connector body of the mating connector. The reinforcing metal fitting includes a fitting guide portion inserted into a fitting recess of the mating fitting guide portion formed at both ends in the direction, and the reinforcing metal fitting has a central covering portion extending in the width direction of the connector body and the central covering portion. A pair of left and right side coverings in which base ends are connected to both ends of the portion, including a side covering extending in the longitudinal direction of the connector body, and the shape in a plan view is substantially U-shaped. The central covering portion covers most of the upper surface of the fitting guide portion, and a side plate portion extending downward over most of the one side edge is connected to one side edge of the side covering portion. The side plate portion covers the outer surface of the fitting guide portion and the outer surface of the convex portion, and is connected to the substrate in a range closer to the terminal than the center at the lower end of the side plate portion extending in the longitudinal direction of the connector body. The board connection portion to be connected is connected, and the free end of the board connection portion is outside the width direction of the connector body with respect to the outer surface of the convex portion, and the connector is more than the free end of the tail portion of the terminal. It is located inside the width direction of the main body.

In other connectors, the board connection portion is smaller in the longitudinal dimension of the connector body than the side plate portion.

In still other connectors, the board connection portion extends from the lower end of the side plate portion toward the outside in the width direction of the connector body.

In still another connector, the side plate portion is in contact with the mating reinforcing metal fitting loaded in the mating connector main body.

In still another connector, the mating reinforcing metal fitting further includes a contact arm portion located on the inner wall surface side of the fitting recess of the mating mating guide portion and in contact with the side plate portion .

In still other connectors, the mating reinforcing fitting further covers most of the upper surface of the mating guide.

The connector pair has the connector and a mating connector that fits the connector.

According to the present disclosure, the connector ensures that the fitting guide portion of the connector body is not damaged or damaged during the fitting operation, and the conduction state between the reinforcing metal fitting and the mating reinforcing metal fitting is reliably maintained. This allows the mating with the mating connector to be reliably maintained and reliability to be improved.

That is, the second housing 111 is formed by filling the cavity of the mold in which the second terminal 161 is set in advance with resin. As a result, the main body of the second terminal 161 is buried in the second housing 111, and the surfaces of the first contact portion 165, the connection portion 164 and the second contact portion 166 are fitted to each side surface of the second convex portion 112. It is integrally attached to the second housing 111 in a state of being exposed to the surface. In this case, ten second terminals 161 are arranged on the left and right at a pitch of, for example, about 0.2 [mm]. The pitch and number of the second terminals 161 can be changed as appropriate.

Functions as an insertion protrusion.

Further, a second reinforcing metal fitting 151 as a mating reinforcing metal fitting is attached to the second protruding end portion 122. The second reinforcing metal fitting 151 is arranged along the outer surface of the second housing 111 at the second protruding end portion 122, and the tip of the holding protruding piece 158 is inside the vicinity of both ends in the longitudinal direction of the second convex portion 112. It is housed and held in the second metal fitting holding recess 126 formed on the side surface.

The second reinforcing metal fitting 151 in the present embodiment is a member integrally formed by punching, bending, or the like on a metal plate, and is an elongated strip-shaped first member extending in the width direction of the second housing 111.

Next, the operation of fitting the first connector 1 and the second connector 101 having the above configuration will be described.

FIG. 5 is a perspective view showing the positional relationship between the first connector and the second connector in the connector fitting process of the present embodiment, and FIG. 6 shows a state in which the connector fitting process of the present embodiment is completed. It is a figure. Note that, in FIG. 6, (a) is a perspective view of the fitted first connector and the second connector, showing a state in which the first connector and the second connector are broken along the lines BB and CC in FIG. 5, (b). ) Is a front view of the fracture surface.

Here, the first connector 1 is connected to a connection pad in which the tail portion 62 of the first terminal 61 is connected to a conductive trace of the first substrate (not shown) by soldering or the like, and the substrate is connected to the first reinforcing metal fitting 51. It is assumed that the portion 56 is surface-mounted on the first substrate by being connected to the connection pad connected to the conductive trace of the first substrate by soldering or the like. The conductive trace connected to the connection pad to which the tail portion 62 of the first terminal 61 is connected is a signal line, and is connected to the connection pad to which the board connection portion 56 of the first reinforcing metal fitting 51 is connected. The conductive trace is assumed to be a power line.

Similarly, the second connector 101 is connected to a connection pad in which the tail portion 162 of the second terminal 161 is connected to a conductive trace of a second substrate (not shown) by soldering or the like, and the second reinforcing metal fitting 151 is connected to the substrate. It is assumed that the portion 156 is surface-mounted on the second substrate by being connected to the connection pad connected to the conductive trace of the second substrate by soldering or the like. The conductive trace connected to the connection pad to which the tail portion 162 of the second terminal 161 is connected is a signal line, and is connected to the connection pad to which the board connection portion 156 of the second reinforcing metal fitting 151 is connected. The conductive trace is assumed to be a power line.

First, as shown in FIG. 5, the operator sets the fitting surface of the first housing 11 of the first connector 1 and the fitting surface of the second housing 111 of the second connector 101 to face each other, and the second The position of the second convex portion 112 of the connector 101 coincides with the position of the corresponding concave groove portion 12a of the first connector 1, and the position of the second protruding end portion 122 of the second connector 101 is the corresponding fitting of the first connector 1. When it matches the position of the recess 22, the alignment between the first connector 1 and the second connector 101 is completed.

In this state, when the first connector 1 and / or the second connector 101 is moved in the direction approaching the mating side, that is, in the fitting direction, the second convex portion 112 and the second protruding end portion 122 of the second connector 101 are moved. Is inserted into the concave groove portion 12a and the fitting recess 22 of the first connector 1. As a result, as shown in FIG. 6, when the fitting of the first connector 1 and the second connector 101 is completed, the first terminal 61 and the second terminal 161 are in a conductive state.

Specifically, the second terminal 161 of the second connector 101 is inserted between the first contact portion 65 and the second contact portion 66 of each first terminal 61, and the first contact portion 65 and the first contact portion 65 of the first terminal 61 are inserted. The first contact portion 165 of the two terminals 161 comes into contact with each other, and the second contact portion 66 of the first terminal 61 and the second contact portion 166 of the second terminal 161 come into contact with each other. As a result, the conductive trace connected to the connection pad on the first board to which the tail portion 62 of the first terminal 61 is connected and the connection pad on the second board to which the tail portion 162 of the second terminal 161 is connected are connected. Conducts with the connected conductive traces.

By the way, since the first connector 1 and the second connector 101 are mounted on the first board and the second board having a large area, the operator can use the fitting surface of the first connector 1 and the fitting surface of the second connector 101. It is not possible to visually check and, and the fitting work is performed by fumbling. Then, since it is a fumbling, accurate alignment cannot be performed, and the position of the first connector 1 and the position of the second connector 101 may be misaligned. For example, the second connector 101 is displaced in the longitudinal direction with respect to the first connector 1, and the fitting surface of the second connector 101 is inclined with respect to the fitting surface of the first connector 1. May become.

In such a state, when the operator moves the first connector 1 and / or the second connector 101 in the mating direction, the end wall portion 21b of the first protruding end portion 21 of any one of the first connectors 1 is subjected to. The second protruding end portion 122 of any one of the second connectors 101 comes into contact with the end wall portion 21b, and the end wall portion 21b is directed from the second protruding end portion 122 in the fitting direction, that is, from top to bottom in FIG. It will be subject to a large pressing force.

However, in the present embodiment, the first reinforcing metal fitting 51 is attached to the first protruding end portion 21, and most of the upper surface 21a and the inner wall end surface 21e of the portion corresponding to the end wall portion 21b in the inner wall portion 21f are the first. 1 Since it is covered by the central guide portion 57 of the reinforcing metal fitting 51, even if a large pressing force is received from the second protruding end portion 122, the pressing force is connected to the substrate from the first main body portion 52 of the first reinforcing metal fitting 51. Since it is transmitted to the first substrate via the portion 56, it is hardly transmitted to the end wall portion 21b. Therefore, the end wall portion 21b is not damaged or damaged.

Moreover, the central guide portion 57 of the first reinforcing metal fitting 51 has a substantially U-shaped cross-sectional shape, has a large geometrical moment of inertia, and has high strength. As a result, even if the pushing pressure transmitted to the end wall portion 21b of the first protruding end portion 21 via the second protruding end portion 122 is large, the pushing pressure is applied by the central guide portion 57 of the first reinforcing metal fitting 51. It can be effectively received, and the pressing force is hardly transmitted to the end wall portion 21b. Therefore, even if the pressing force is large, the end wall portion 21b is not damaged or damaged.

Further, the central guide portion 57 of the first reinforcing metal fitting 51 includes a slanted slope portion 57d. As a result, the second protruding end portion 122 that comes into contact with the central guide portion 57 slides along the slope portion 57d and is smoothly attracted and inserted into the fitting recess 22.

Further, for example, in a state where the second connector 101 is displaced in the width direction with respect to the first connector 1, the second protruding end portion 122 comes into contact with the side wall extension portion 21c of the first protruding end portion 21. However, in the present embodiment, most of the upper surface 21a and the inner wall side surface 21j of the portion corresponding to the side wall extension portion 21c in the inner wall portion 21f is covered by the side guide portion 54 of the first reinforcing metal fitting 51. Even if a large pressing force is received from the second protruding end portion 122, the side wall extension portion 21c is not damaged or damaged.

Further, the side guide portion 54 of the first reinforcing metal fitting 51 includes a slanted slope portion 54d. As a result, the second protruding end portion 122 that comes into contact with the side guide portion 54 slides along the slope portion 54d and is smoothly attracted and inserted into the fitting recess 22.

Even when the second connector 101 is displaced with respect to the first connector 1, the apex of the upper covering portion 57a of the central guide portion 57 and the apex of the upper covering portion 54c of the side guide portion 54 are the contact arm portions 55. Since it is located higher than the apex of the upward curved portion 55d, the second protruding end portion 122 does not come into contact with the contact arm portion 55 first. Therefore, the contact arm portion 55 has flexibility and is not damaged or damaged even if the strength is low.

Further, since the apex of the upper covering portion 57a of the central guide portion 57 and the apex of the upper covering portion 54c of the side guide portion 54 are higher than the upper surface 14a of the side wall portion 14 and the upper surface 13a of the first convex portion 13. , The second protruding end portion 122 does not first come into contact with the side wall portion 14 and the first convex portion 13. Therefore, the side wall portion 14 and the first convex portion 13 are not damaged or damaged.

However, in a state where the second connector 101 is largely displaced with respect to the first connector 1, the second protruding end portion 122 does not abut on the first reinforcing metal fitting 51, but rather on the side wall portion 14 and the first convex portion 13. There is a possibility that they will come into contact first, but even in such a case, the apex of the upward curved portion 55d of the contact arm portion 55 and each portion of the first terminal 61 are the upper surface 14a and the first portion of the side wall portion 14. Since it is located at a position equal to or lower than the upper surface 13a of the convex portion 13, the contact arm portion 55 and the first terminal 61 are not subjected to pressing force from the second protruding end portion 122. Therefore, the contact arm portion 55 and the first terminal 61 are not damaged or damaged.

By the way, since the second housing 111 of the second connector 101 has a smaller dimension in the lateral direction, that is, in the width direction, as compared with the first housing 11 of the first connector 1, the second protruding end portion 122 has a smaller dimension. Compared with the end wall portion 21b of the first protruding end portion 21, the strength is high and the damage is less likely to occur. Therefore, the second main body portion 152, the central covering portion 157, the side covering portion 154, and the holding protrusion piece 158 in the second reinforcing metal fitting 151 can be omitted as appropriate.

When the fitting of the first connector 1 and the second connector 101 is completed, the first terminal 61 and the second terminal 161 are in a conductive state, and the first reinforcing metal fitting 51 and the first reinforcing metal fitting 51 included in the first connector 1 are provided. The second reinforcing metal fitting 151 included in the two connectors 101 is in a state of being engaged with each other. As a result, the first reinforcing metal fitting 51 and the second reinforcing metal fitting 151 are in a conductive state, and the continuity of the power line is maintained.

Specifically, the second reinforcing metal fitting 151 is inserted inside the first reinforcing metal fitting 51, and the downward curved portion 55b in the left and right contact arm portions 55 of the first reinforcing metal fitting 51 is the left and right contact side plate portions of the second reinforcing metal fitting 151. Contact 155. At this time, the downward curved portion 55b is displaced downward as the second reinforcing metal fitting 151 relatively moves downward, and is displaced outward in the width direction of the first housing 11, that is, outward. Then, due to the springiness of the contact arm portion 55 and the connecting arm portion 53 to which the contact arm portion 55 is connected, that is, due to the function as a spring portion, the surface of the downward curved portion 55b becomes the surface of the contact side plate portion 155. Pressed.

As a result, the contact between the surface of the downward curved portion 55b and the surface of the contact side plate portion 155 is reliably maintained, so that the continuity between the first reinforcing metal fitting 51 and the second reinforcing metal fitting 151 is reliably maintained.

Here, the connecting arm portion 53 has a long spring length from the base end connected to the left and right ends of the first main body portion 52 to the tip to which the contact arm portion 55 is connected, that is, to the free end. Further, the free end of the connecting arm portion 53 is located below because it is the tip of the second connecting arm portion 53b bent in a substantially crank shape, and thus extends upward from the free end located below. The contact arm portion 55 is also provided with a long spring length up to the downward curved portion 55b. Therefore, the downward curved portion 55b is located at the free end of the connecting arm portion 53 and the contact arm portion 55, which are spring portions having an extremely long spring length, and the elastic displacement amount is extremely large. As a result, the vibration and impact generated when the electronic device or the like on which the first board and the second board are mounted are dropped or receives an external force are transmitted, and the second reinforcing metal fitting 51 is transmitted to the second reinforcing metal fitting 51. Even when the 151 is relatively displaced, the downward curved portion 55b can maintain the contact state by following the displacement of the contact side plate portion 155, so that the first reinforcing metal fitting 51 and the second reinforcing metal fitting 151 can be maintained. The continuity state with and is surely maintained, and the so-called momentary interruption, in which the continuity is temporarily cut off, does not occur.

As described above, even when the second connector 101 is displaced with respect to the first connector 1, the second protruding end portion 122 does not first come into contact with the contact arm portion 55, and the contact arm portion 55 does not receive pressing force from the second protruding end 122. Therefore, the connecting arm portion 53 and the contact arm portion 55 can be made flexible, and the downward curved portion 55b can be flexibly and greatly displaced.

Further, a side guide portion 54 is connected in the middle of the connecting arm portion 53, and when the side guide portion 54 is displaced downward and outward to some extent, the lower end portion 54b of the inner covering portion 54a becomes the inner convex portion 27. Since it abuts on the support surface 27a and the inner wall side surface 21j, the displacement is stopped. Therefore, the upper covering portion 54c does not come into contact with the upper surface 21a of the portion of the inner wall portion 21f corresponding to the end wall portion 21b, and the upper surface 21a is not damaged or damaged.

Further, since the displacement of the side guide portion 54 is stopped in the middle, the first connecting arm portion 53a of the connecting arm portions 53 cannot be displaced if it is displaced to some extent, and only the second connecting arm portion 53b can be displaced. .. Therefore, the downward curved portion 55b is a long spring portion having the entire connecting arm portion 53 and the contact arm portion 55 as the spring length until the displacement amount is within a certain range, that is, until the displacement of the side guide portion 54 is stopped. When the displacement amount exceeds the above range, the displacement is performed while exerting a strong spring force by the relatively short spring portion having the second connecting arm portion 53b and the contact arm portion 55 as the spring length. As a result, the downward curved portion 55b has a large displacement amount and a strong spring force, so that the contact state with the contact side plate portion 155 can be maintained, and the first reinforcing metal fitting 51 and the second reinforcing metal fitting 51 can be maintained. The conduction state with 151 is surely maintained, and the so-called momentary interruption, in which the continuity is temporarily cut off, does not occur.

As shown in FIG. 6, when the fitting of the first connector 1 and the second connector 101 is completed, the downward curved portion 55b of the contact arm portion 55 is displaced outward by the contact side plate portion 155. Therefore, the lower end portion 55c enters the contact arm portion lower end accommodating hole 28b. When moving the first connector 1 and / or the second connector 101 in a direction away from the mating side, that is, in an anti-fitting direction in order to release the fitting between the first connector 1 and the second connector 101, the first 2. A force in a direction of upwardly pulling out from the first housing 11 acts on the contact arm portion 55 of the first reinforcing metal fitting 51 holding the reinforcing metal fitting 151. However, since the lower end portion 55c has entered and engaged with the contact arm portion lower end accommodating hole 28b, the lower end portion 55c is prevented from being displaced upward, and the lower curved portion 55b is turned over. The raising is prevented, and the contact arm portion 55 is prevented from being pulled out from the first housing 11.

As described above, in the present embodiment, the first connector 1 is the first housing 11, the first terminal 61 loaded in the first housing 11, and the first reinforcing metal fitting 51 loaded in the first housing 11. And. The first housing 11 is a first protruding end portion 21 formed at both ends in the longitudinal direction, and is fitted with a second protruding end portion 122 formed at both ends in the longitudinal direction of the second housing 111 of the second connector 101. A matching first protruding end portion 21 is included, and the first reinforcing metal fitting 51 includes a pair of left and right contact arm portions 55 and a pair of left and right side guide portions 54 arranged on the first protruding end portion 21. When the first housing 11 is fitted with the second housing 111, the side guide portion 54 guides the second protruding end portion 122, and the contact arm portion 55 with the second reinforcing metal fitting 151 loaded in the second housing 111. Contact.

As a result, the first protruding end portion 21 of the first housing 11 is not damaged or damaged during the fitting operation, and the conduction state between the first reinforcing metal fitting 51 and the second reinforcing metal fitting 151 is maintained. It can be reliably maintained, the mating with the second connector 101 is reliably maintained, and reliability can be improved.

Further, the first reinforcing metal fitting 51 includes a first main body portion 52 extending in the width direction of the first housing 11, and a pair of left and right connecting arm portions 53 having base ends connected to both ends of the first main body portion 52. Including, the contact arm portion 55 is connected to the free end of the connecting arm portion 53, and the side guide portion 54 is connected to a position closer to the base end than the free end of the connecting arm portion 53. Therefore, the spring length up to the contact arm portion 55 is long, and the elastic displacement amount of the contact arm portion 55 can be increased.

Further, the first protruding end portion 21 is a pair of left and right fitting recesses 22 into which the second protruding end portion 122 is inserted, and a pair of left and right sides that are inner wall surfaces of the fitting recess 22 and extend in the longitudinal direction of the first housing 11. The side guide portion 54 covers at least a part of the inner wall side surface 21j including the inner wall side surface 21j. Therefore, the inner wall side surface 21j is not damaged or damaged.

Further, the first protruding end portion 21 includes an inner wall end surface 21e which is an inner wall surface of the fitting recess 22 and extends in the width direction of the first housing 11, and the first reinforcing metal fitting 51 is at least one of the inner wall end surfaces 21e. A central guide portion 57 that covers the portion and includes a central guide portion 57 that guides the second protruding end portion 122 when the first housing 11 is fitted with the second housing 111 of the second connector 101. Therefore, the inner wall end surface 21e is not damaged or damaged.

Further, the side guide portion 54 can be elastically displaced downward and outward due to the deformation of the connecting arm portion 53, and the lower end portion 54b of the side guide portion 54 abuts on the support surface 27a and the inner wall side surface 21j. Then, the downward and outward displacement is stopped. As a result, the side guide portion 54 can be stopped without abutting on the upper end of the first protruding end portion 21, and the upper end of the first protruding end portion 21 is damaged or damaged. There is no.

Further, the contact arm portion 55 can be elastically displaced downward and outward even if the lateral guide portion 54 stops the displacement downward and outward. As a result, the contact arm portion 55 has both a large displacement amount and a strong spring force, so that the contact state with the second reinforcing metal fitting 151 can be reliably maintained.

Further, the contact arm portion 55 includes a lower curved portion 55b having a curved convex surface and a lower end portion 55c, and when the lower curved portion 55b comes into contact with the second reinforcing metal fitting 151, the lower end portion 55c is displaced outward. It enters the contact arm portion lower end accommodating hole 28b formed in the first housing 11. As a result, the lower end portion 55c enters the contact arm portion lower end accommodating hole 28b and is engaged, so that when the first connector 1 and / or the second connector 101 is moved in the anti-fitting direction, the contact is made. Even if a force in the direction of pulling out from the first housing 11 acts on the arm portion 55, the lower end portion 55c is prevented from being displaced upward, the downward curved portion 55b is prevented from rolling up, and the contact arm portion 55 is formed. It is prevented from being pulled out from the first housing 11.
