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. Such a connector is attached to each of the surfaces of the pair of circuit boards that face each other, and is fitted to and electrically connected to each other. In addition, a technique has been proposed in which the reinforcing metal fittings attached to both ends function as lock members to maintain the fitted state with the mating connector (for example, refer to 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 first housing as a housing of a second connector mounted on a second circuit board not shown. 2 housings. By fitting the first connector and the second connector, the first circuit board and the second circuit board are electrically connected. In the drawing, 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 relatively attached to the second connector. Can be fitted close 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 of the side wall portion 814 in the longitudinal direction. A fitting recess 822 is formed in each fitting guide 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.

Also, 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 member 951 is attached to the fitting convex portion 922.

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

However, in the above-mentioned conventional connector, the first housing 811 or the second housing 911 may be damaged or damaged during the fitting operation. When fitting the first connector attached to the first circuit board and the second connector attached to the second circuit board, the operator may fit the fitting surface of the first housing 811 and the second housing 911 depending on working conditions. There is a case where the fitting surface cannot be visually observed and the fitting work must be done by feeling. In particular, in recent years, since the board-to-board connector has been downsized and the height has been reduced, it is difficult for an 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 groping. Then, the fitting protrusion 922 of the second housing 911 is inserted into the fitting recess 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 when 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 receive a large pressing force, and may be damaged or damaged. In particular, the fitting guide portions 821 formed at both ends in the longitudinal direction of the first housing 811 are relatively thin, and therefore, for example, when the end portions in the longitudinal direction of the second housing 911 abut obliquely, they are easily damaged. Resulting in.

Further, by connecting the first reinforcing metal fitting 851 and the second reinforcing metal fitting 951 to the power supply lines of the first circuit board and the second circuit board, the first reinforcing metal fitting 851 and the second reinforcing metal fitting 951 are connected to the electric circuit. Although it can be used as a member, the engaging protrusion 858 of the first reinforcing metal member 851 does not have sufficient flexibility. Therefore, when vibration or impact generated when an electronic device or the like on which the first circuit board and the second circuit board are mounted falls or receives an external force is transmitted, the first reinforcing metal fitting 851 and the second reinforcing metal member 851 are provided. It is conceivable that the contact with the metal fitting 951 will not be maintained, and it will not be possible to ensure sufficient conduction as a power supply line.

Here, by solving the problems of the conventional connector, the fitting guide portion of the connector body is not damaged or damaged during the fitting work, and It is an object of the present invention to provide a highly reliable connector that can surely maintain a conductive state and reliably retain fitting with a mating connector.

A main body portion extending in the width direction of the connector main body, and a pair of left and right connecting arm portions whose base ends are connected to both ends of the main body portion, each contact arm portion being the base end portion of each connecting arm portion. Connected to the opposite side, each connection arm portion includes a first connection arm portion connected to the main body portion, and a second connection arm portion in the range from the first connection arm portion to the contact arm portion, The reinforcing metal fitting is housed in a metal fitting holding recess formed in the fitting guide portion, and the first connecting arm portion is a first arm housing opening of the metal fitting holding recess and is open to the outside. The first connection arm portion is accommodated in the first arm portion accommodation opening, the lower end of the first connection arm portion is located above the lower surface of the first arm portion accommodation opening, and is elastically displaceable downward and outward. Ri, the second connection arm portions has a substantially crank shape watched from the side, you position on the mounting surface nearer the tip of the first connecting arm section.

In another connector, the contact arm portion can be elastically displaced downward and outward by the deformation of the connection arm portion.

In still another connector, the contact arm portion further includes a lower curved portion having a curved convex surface and a lower end portion, and when the lower curved portion comes into contact with a mating reinforcing metal member, the lower end portion moves outward. It is displaced and enters the contact arm lower end accommodating hole formed in the connector body.

In still another connector, the contact arm portion is connected to a free end of the connection arm portion.

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

According to the present disclosure, in the connector, the fitting guide portion of the connector body is not damaged or damaged during the fitting work, and the conductive state between the reinforcing metal fitting and the counterpart reinforcing metal fitting is reliably maintained. Therefore, the fitting with the mating connector can be reliably held, and the reliability can be improved.

The second terminal 161 is integrated with the second housing 111 by overmolding or insert molding. That is, the second housing 111 is molded by filling the resin into the cavity of the mold in which the second terminals 161 are set in advance. 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 connecting portion 164, and the second contact portion 166 are fitted to the respective side surfaces of the second convex portion 112 and the fitting.

With shape. Then, the second projecting end portion 122 is inserted into the fitting recess 22 of the first projecting end portion 21 included in the first connector 1 when the first connector 1 and the second connector 101 are fitted together. Functions as an insertion protrusion.

Further, a second reinforcing metal member 151 as a counterpart reinforcing metal member is attached to the second projecting end portion 122. The second reinforcing metal member 151 is arranged along the outer surface of the second housing 111 at the second projecting end portion 122, and the tip of the retaining projecting piece 158 is located inside the second projecting portion 112 near both ends in the longitudinal direction.

Next, the operation of fitting the first connector 1 and the second connector 101 having the above-described 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 this embodiment, and FIG. 6 shows a state where the connector fitting process of this embodiment is completed. It is a figure. In addition, in FIG. 6, (a) is a perspective view of the fitted first connector and second connector, and shows a state of being broken along line BB and line CC in FIG. 5, (b) ) Is a front view of the fracture surface.

Here, the first connector 1 is connected by soldering or the like to the connection pad where the tail portion 62 of the first terminal 61 is connected to the conductive trace of the first board (not shown), and the board connection of 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 pads connected to the conductive traces 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 connected to the connection pad to which the board connecting portion 56 of the first reinforcing metal fitting 51 is connected. Conductive traces shall be power lines.

Similarly, in the second connector 101, the tail portion 162 of the second terminal 161 is connected to a connection pad connected to a conductive trace of a second substrate (not shown) by soldering or the like, and the second reinforcing metal member 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 connecting portion 156 of the second reinforcing metal member 151 is connected. The conductive traces shall be power lines.

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 position of the second convex portion 112 of the connector 101 matches the position of the corresponding concave groove portion 12a of the first connector 1, and the position of the second projecting end portion 122 of the second connector 101 corresponds to the corresponding fitting of the first connector 1. When the position of the recess 22 is matched, the alignment of 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 toward the mating side, that is, in the fitting direction, the second convex portion 112 and the second projecting end portion 122 of the second connector 101 are moved. Is inserted into the concave groove portion 12 a and the fitting concave portion 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 brought into conduction.

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 of the first terminal 61 and the The first contact portion 165 of the second terminal 161 contacts, and the second contact portion 66 of the first terminal 61 contacts the second contact portion 166 of the second terminal 161. As a result, a conductive trace connected to the connection pad on the first substrate to which the tail portion 62 of the first terminal 61 is connected and a connection pad on the second substrate to which the tail portion 162 of the second terminal 161 is connected. The connected conductive trace is electrically connected.

By the way, since the first connector 1 and the second connector 101 are respectively mounted on the first substrate and the second substrate having a large area, the operator is required to attach the first connector 1 and the second connector 101 to each other. Since it is not possible to visually check and, the fitting work will be performed by feeling. Then, since it is a groping, accurate alignment cannot be performed, and the position of the first connector 1 and the position of the second connector 101 may deviate. For example, a state in which 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 be.

In this state, when the operator moves the first connector 1 and/or the second connector 101 in the fitting direction, the end wall 21b of the first protruding end 21 of either one of the first connectors 1 One of the second projecting end portions 122 of the second connector 101 comes into contact, and the end wall portion 21b faces from the second projecting end portion 122 in the fitting direction, that is, from top to bottom in FIG. You will receive 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 inner wall portion 21f corresponding to the end wall portion 21b are Since it is covered with the central guide portion 57 of the first reinforcing metal fitting 51, even if a large pressing force is applied from the second projecting end portion 122, the pressing force is applied from the first main body portion 52 of the first reinforcing metal fitting 51 to the substrate connection. 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.

In addition, the central guide portion 57 of the first reinforcing metal fitting 51 has a substantially U-shaped cross section, has a large section modulus, and has high strength. Thereby, even if the pressing force transmitted to the end wall portion 21b of the first protruding end portion 21 via the second protruding end portion 122 is large, the central guide portion 57 of the first reinforcing metal fitting 51 exerts the pressing force. 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 is provided with a slanted slope portion 57d. As a result, the second protruding end portion 122 that abuts the central guide portion 57 slides along the slope portion 57d, and is smoothly guided and inserted into the fitting concave portion 22.

Further, for example, when the second connector 101 is displaced in the width direction with respect to the first connector 1, the second projecting end portion 122 comes into contact with the side wall extension portion 21c of the first projecting end portion 21. However, in the present embodiment, most of the upper surface 21a and the inner wall side surface 21j of the inner wall portion 21f corresponding to the side wall extension portion 21c are covered by the side guide portion 54 of the first reinforcing metal fitting 51. Even if a large pressing force is applied from the second projecting 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 is provided with a slanted slope portion 54d. As a result, the second projecting end portion 122 that abuts the side guide portion 54 slides along the slope portion 54d and is smoothly guided and inserted into the fitting concave portion 22.

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

Further, the vertex of the upper cover portion 57a of the central guide portion 57 and the vertex of the upper cover portion 54c of the side guide portion 54 are located 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 the state where the second connector 101 is largely displaced with respect to the first connector 1, the second projecting end portion 122 does not abut the first reinforcing metal fitting 51, and the side wall portion 14 and the first projecting portion 13 are not contacted. Although there is a possibility that they will come into contact with each other first, even in such a case, the apex of the upward bending portion 55d of the contact arm portion 55 and the respective portions of the first terminal 61 will not contact the upper surface 14a of the side wall portion 14 and the first portion. Since the contact arm 55 and the first terminal 61 are located at the same or lower position as the upper surface 13a of the protrusion 13, the contact arm 55 and the first terminal 61 do not receive a pressing force from the second protruding end 122. Therefore, the contact arm 55 and the first terminal 61 are not damaged or damaged.

By the way, the second housing 111 of the second connector 101 has a smaller dimension in the lateral direction, that is, the width direction than the first housing 11 of the first connector 1, so that the second protruding end portion 122 is As compared with the end wall portion 21b of the first projecting end portion 21, it has higher strength and is less likely to be damaged. Therefore, the second main body portion 152, the central cover portion 157, the side cover portion 154, and the holding projection piece 158 in the second reinforcing metal member 151 can be appropriately omitted.

Then, when the fitting between the first connector 1 and the second connector 101 is completed, the first terminal 61 and the second terminal 161 are brought into conduction, and the first reinforcing metal fitting 51 and the The second reinforcing metal member 151 of the two-connector 101 is engaged with each other. As a result, the first reinforcing metal fitting 51 and the second reinforcing metal fitting 151 are brought into conduction with each other, and conduction of the power line is maintained.

In detail, the second reinforcing metal fitting 151 is inserted inside the first reinforcing metal fitting 51, and the lower curved portions 55b of the left and right contact arm portions 55 of the first reinforcing metal fitting 51 have 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 member 151 moves relatively downward, and is displaced outward in the width direction of the first housing 11, that is, outward. Then, due to the spring property of the contact arm portion 55 and the connection 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 conduction between the first reinforcing metal fitting 51 and the second reinforcing metal fitting 151 is reliably maintained.

Here, the connection arm portion 53 has a long spring length from a base end connected to both left and right ends of the first main body portion 52 to a tip end to which the contact arm portion 55 is connected, that is, a free end. Further, the free end of the connecting arm portion 53 is located at the lower end because it is the tip of the second connecting arm portion 53b bent in a substantially crank shape, and extends upward from the free end located at such a lower portion. The contact arm portion 55 also has a long spring length up to the downward curved portion 55b. Therefore, the downward curved portion 55b is located at the free ends of the connection arm portion 53 and the contact arm portion 55, which are spring portions having an extremely long spring length, and the amount of elastic displacement is extremely large. As a result, vibrations and shocks generated when the electronic device or the like on which the first board and the second board are mounted drop or receive an external force are transmitted, and the second reinforcing metal fitting 51 is connected to the second reinforcing metal fitting 51. Even when 151 is relatively displaced, the downward curved portion 55b can follow the displacement of the contact side plate portion 155 and maintain the contact state, so that the first reinforcing metal fitting 51 and the second reinforcing metal fitting 151 can be maintained. There is no occurrence of a phenomenon called so-called momentary interruption, in which the conduction state with is reliably maintained and the conduction is temporarily cut off.

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 contact first. 55 is not pressed by 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 largely displaced.

In addition, 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 cover portion 54a becomes the inner convex portion 27 of 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 cover 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 midway, the first connecting arm portion 53a of the connecting arm portions 53 cannot be displaced if displaced to some extent, and only the second connecting arm portion 53b can be displaced. .. Therefore, the downward bending portion 55b has a long spring portion having the entire connection arm portion 53 and the contact arm portion 55 as the spring length until the displacement amount reaches 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 second connection arm portion 53b and the contact arm portion 55 are displaced while relatively strong spring force is exerted by a relatively short spring portion. As a result, the downward curved portion 55b has both 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 state of continuity with 151 is reliably maintained, and the phenomenon of so-called momentary interruption in which conduction 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 55 b of the contact arm portion 55 is in a state of being displaced outward by the contact side plate portion 155. Therefore, the lower end 55c enters the contact arm lower end accommodating hole 28b. In order to release the fitting between the first connector 1 and the second connector 101, when moving the first connector 1 and/or the second connector 101 in the direction away from the mating side, that is, in the anti-fitting direction, A force in a direction of pulling out upward from the first housing 11 acts on the contact arm portion 55 of the first reinforcing metal fitting 51 holding the second reinforcing metal fitting 151. However, since the lower end portion 55c enters the contact arm lower end accommodation hole 28b and is in the engaged state, the lower end portion 55c is prevented from being displaced upward, and the lower curved portion 55b is turned up. The rising is prevented, and the contact arm 55 is prevented from being pulled out from the first housing 11.

As described above, in the present embodiment, the first connector 1 includes the first housing 11, the first terminals 61 loaded in the first housing 11, and the first reinforcing metal fitting 51 loaded in the first housing 11. With. The first housing 11 is a first projecting end portion 21 formed at both ends in the longitudinal direction, and is fitted with second projecting end portions 122 formed at both ends in the longitudinal direction of the second housing 111 of the second connector 101. 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 at 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 projecting end portion 122, and the contact arm portion 55 with the second reinforcing metal member 151 mounted 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 work, 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 fitting with the second connector 101 is reliably retained, and the reliability can be improved.

In addition, 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 whose base ends are 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 55 is long, and the elastic displacement of the contact arm 55 can be increased.

Further, the first protruding end portion 21 includes a fitting concave portion 22 into which the second protruding end portion 122 is inserted, and a pair of left and right inner wall surfaces of the fitting concave portion 22 extending 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 that 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 includes at least one of the inner wall end surface 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 by the deformation of the connecting arm portion 53, and the lower end portion 54b of the side guide portion 54 abuts the support surface 27a and the inner wall side surface 21j. Then, the downward and outward displacement is stopped. Accordingly, the side guide portion 54 can be stopped without coming into contact with the upper end of the first projecting end portion 21, and the upper end of the first projecting end portion 21 may be 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 downward and outward displacement. 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 member 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. When the lower curved portion 55b comes into contact with the second reinforcing metal member 151, the lower end portion 55c is displaced outward. It enters into the contact arm lower end accommodation hole 28b formed in the first housing 11. As a result, the lower end portion 55c enters into the contact arm lower end accommodation hole 28b and is engaged therewith, so that when the first connector 1 and/or the second connector 101 is moved in the anti-fitting direction, contact is made. Even if a force is applied to the arm portion 55 in the direction of pulling it upward from the first housing 11, the upper end of the lower end portion 55c is prevented from being displaced upward, the curving of the lower curved portion 55b is prevented, and the contact arm portion 55 is Extraction from the first housing 11 is prevented.
