Description

  The present invention relates to a relay electrical connector and an electrical connection assembly capable of absorbing a relative position error between two circuit boards.

  As a relay electrical connector of this type, a connector disclosed in FIG. 3 is known as a preferred embodiment of Patent Document 1. The connector of this patent document 1 is formed as a coaxial connector, and is connected between the two central conductors located on the same axis and between the two central conductors. Between the two outer conductor parts and the two outer conductor parts having an annular shape located on the outer periphery of the center conductor via an insulating disk holding each of the two center conductors. And a cylindrical sleeve that surrounds the two outer conductor parts and the compression coil spring and guides and supports one of the two outer conductor parts so as to be movable in the axial direction. Thus, each end portion of the center conductor protrudes in the axial direction from the corresponding outer conductor part. The connector having such a configuration is in use by connecting the central conductor and the outer conductor part on each end side of the connector to the respective coaxial connectors attached to two circuit boards or the like.

  When the connector of Patent Document 1 is in use and there is an error in the relative position between the two circuit boards, one outer conductor component is attached to the sleeve while receiving the force from the coil spring. The two outer conductor parts are guided and are connected to the circuit board together with the corresponding central conductors via the insulating disks while being relatively close to each other.

Special table 2010-531527

  In the connector of Patent Document 1, since the two central conductors can be contacted and separated in the axial direction, even if there is an error in the relative position between the circuit boards, this can be handled.

  However, in Patent Document 1, in order to allow the relative position error, the center conductor is divided into two parts, and a conductor bellows is provided for electrical connection between the center conductors, and the center conductor corresponds to the center conductor. The outer conductor parts are also divided into two parts, and a coil spring is provided to elastically press both outer conductor parts in the axial direction, and one of the outer conductor parts is axially arranged in the sleeve. The structure is movable, and the overall structure is extremely complicated.

  Such a complex structure has several disadvantages. First, as the number of members is large and the manufacturing cost increases, the assembly becomes complicated. Second, there are many relative movement points between the members, and there is a possibility that the electrical contact between the central conductor or the outer conductor member and the sleeve becomes unstable.

  In view of such circumstances, it is an object of the present invention to provide a relay electrical connector and an electrical connection assembly that are simple in structure, have a small number of components, and can sufficiently cope with errors in the relative positions of circuit boards.

  The above-described problems are solved by the relay electrical connector according to the first invention and the electrical connection assembly according to the second invention.

<First invention> (Relay electrical connector)
The relay electrical connector according to the first invention is a relay electrical for electrically connecting the first connection portion provided on the first circuit board and the second connection portion provided on the second circuit board. A connector having a housing and terminals supported by the housing.

  In such a relay electrical connector, in the present invention, the housing has a plurality of housing members assembled between the first circuit board and the second circuit board, and a housing portion formed in the housing. A plurality of cables with terminals provided with the terminals on at least one end side of the electric cable, and the plurality of housing members correspond to a first connection portion provided on the first circuit board. And a second housing member corresponding to a second connecting portion provided on the second circuit board, at least the first housing member being a corresponding circuit. Relative movement between the first housing member and the second housing member is possible in a direction perpendicular to the surface of the substrate, and the first housing member is connected to the cable with terminal. Has a first supporting portion for supporting an end side, the second housing member is characterized by having a second support portion for supporting the other end of the cable with the terminal.

  In the first invention, the housing is divided into a plurality of housing members, and even if there is an error (displacement) in the relative position between the circuit boards in use, at least the first housing member is deformed by the bending of the cable with terminal. The relative movement between the second housing members is allowed, and the error is absorbed. In this first invention, among the members constituting the relay electrical connector, only the housing is formed in a divided manner, and friction due to relative movement between parts other than the housing does not occur. Since the structure is simple and the number of parts is small, the assembly of the connector is easy and inexpensive.

  In the first invention, the housing may house the cable with terminal in a bent state.

  In the first invention, the first housing member is provided with a plurality of terminals, with one direction parallel to the surface of the first circuit board and the second housing parallel to the surface of the second circuit board. The cables are arranged and held, and the terminals-attached cable may have the terminals of the terminals-attached cable arranged in a staggered manner in the arrangement direction.

  By arranging the terminals in a staggered manner in this way, the plurality of cables with terminals are symmetrical in the connector width direction perpendicular to the arrangement direction when viewed in the arrangement direction of the cables with terminals. Are alternately arranged. Therefore, the force acting on the housing, for example, the elastic force of the cable with terminal, can be used as a symmetrical action distribution to eliminate the bias. In addition, a sufficient distance can be secured between the terminals of the cable with terminals adjacent in the arrangement direction.

  In the first invention, the first housing member and the second housing member are movable relative to each other in directions parallel to the corresponding surface of the first circuit board and the surface of the second circuit board. It is good to be. With this configuration, not only in a direction perpendicular to the surface of the corresponding circuit board but also in a direction parallel to the surface, the first housing member and the second housing member can move relative to each other. An error in the relative position between circuit boards can be absorbed.

  In the first invention, the first housing portion formed in the first housing member and the second housing portion formed in the second housing member are perpendicular to the surface of the corresponding circuit board. The first housing member has a portion of the opening of the first housing portion facing the first circuit board, and a portion of the cable with a terminal extending outward from the opening. A first restricting member for restricting the protrusion is attached, and the second housing member closes a part of the opening of the second accommodating portion facing the second circuit board and outwards from the opening. A second restricting member that restricts the protrusion of the terminal-attached cable may be attached.

  By providing the restricting member in this way, the protrusion of the cable with terminal from the housing member, and thus the removal of the cable with terminal is prevented.

  In the first invention, the first restriction member and the second restriction member are metal members, and may be attached to the first housing member and the second housing member, respectively. Thus, the shielding effect is acquired by making a control member into a metal member.

<Second invention> (Electric connection assembly)
An electrical connection assembly according to the second invention is provided in the relay electrical connector according to the first invention, the first connection body having the first connection portion provided in the first circuit board, and the second circuit board. And at least one of the first connection body and the second connection body has a guide surface for guiding a corresponding housing member to a normal connection position. It also has a formed guide member.

  In the second invention, as described above, the relative movement between the housing members of the relay electrical connector absorbs the error in the relative position between the circuit boards, and at least one of the first connection body and the second connection body. The corresponding housing member can be easily guided to the normal connection position by the guide surface of the guide member provided on the housing.

  In the second invention, the guide member has a peripheral wall portion that is positioned on the surface of the circuit board so as to surround the connection portion and is formed with a receiving portion for receiving the housing member, and the guide surface is formed on the peripheral wall portion. It is good also as being done.

  In the second invention, a plurality of connecting portions are arranged at intervals in the receiving portion of the guide member, and the guide member is directed from the inner wall surface of the peripheral wall portion toward the receiving portion inward between the adjacent connecting portions. It has a protruding partition wall, and the partition wall may be formed as a guide surface with an inclined surface inclined toward the circuit board as it goes inward of the receiving part.

  Thus, by forming the guide surface on the partition wall protruding from the inner wall surface of the peripheral wall portion, the housing member brought into the receiving portion can be reliably guided to the normal connection position.

  In the second invention, at least a part of the guide surface of the guide member may be set to a height that prevents contact between the end surface of the housing member received by the guide member and the connection portion. By setting the guide surface of the guide member to such a height, when the housing is attached to the circuit board via the terminal, the contact between the end surface of the housing member and the connection portion is prevented, and the connection portion is damaged. Is prevented.

  As described above, in the present invention, only the housing is divided into a plurality of housing members, and the first housing member and the second housing member can be moved relative to each other, and one end side of the cable with terminal is provided. Is supported by the first housing member, and the second housing member is supported by the second housing member on the other end of the cable with terminal, so that the structure is simple, the number of components is low, and the relay electrical connector and the electrical are easy to assemble.

  As shown in FIG. 2A and FIGS. 5A and 5B, the upper end portions of the pair of side walls 31 of the second housing member 30, that is, the portions located above the upper plate portion 35, A second support portion 36 for accommodating and supporting the two terminals 43 is formed in a staggered pattern. Since each second support portion 36 has the same shape as the first support portion 26 of the first housing member 20 described above, description thereof is omitted.

  As shown in FIGS. 5A and 5B, the lower half of the second housing member 30 receives the upper half of the first housing member 20 and the interposition member 50 from below. A recess 37 is formed surrounded by a peripheral wall. The upper inner wall surface of the receiving recess 37 is formed with an opening at a position corresponding to each second housing portion 34, and the receiving recess 37 communicates with each second housing portion 34 through the opening. As a result, as seen in FIGS. 5A and 5B, the terminal-equipped cable 40 extends over both the housing portions of the first housing portion 24 of the first housing member 20 and the second housing portion 34 of the second housing member 30. Can be accommodated. 5A and 5B, the upper inner wall surface of the receiving recess 37 is the upper surface of the step portion 27 of the first housing member 20 (the surface forming the step portion 27) in the peripheral region. Of these, the interposition member 50 is accommodated in a space formed between them (surface perpendicular to the vertical direction) and the vertical direction (see also FIG. 7).

  The receiving recess 37 is formed to be slightly larger than the upper half of the first housing member 20 accommodated in the receiving recess 37 in the cable arrangement direction and the connector width direction. That is, play is provided between the housing members 20 and 30 in the cable arrangement direction and the connector width direction, and the housing members 20 and 30 are within this play range due to the bending of the cable with terminal 40 in these directions. Relative movement is allowed.

  As shown in FIG. 2A, the end wall 32 of the second housing member 30 has a protruding portion in which the lower half protrudes outward in the cable arrangement direction from the upper half. A concave strip 32A extending in the vertical direction is formed in the central region of the connector width direction. The concave portion 32A is submerged from the inner wall surface (not shown) of the end wall 32, and the upper end opens at the upper surface position of the protruding portion of the lower half of the end wall 32 as shown in FIG. And the lower end is closed. The concave portion 32A receives the upper locking claw portion 28A of the upper elastic arm portion 28 of the first housing member 20 in a state where the housing members 20 and 30 are assembled. At this time, the lower end surface (lower inner wall surface) of the concave strip portion 32A faces the lower surface of the upper locking claw portion 28A at a position below the upper locking claw portion 28A, and against the upper locking claw portion 28A. It functions as a locked surface that can be locked. Since the concave portion 32A extends in the vertical direction as described above, the upper locking claw portion 28A is movable in the vertical direction within the concave portion 32A. Further, the concave strip portion 32A is larger than the upper locking claw portion 28A in the connector width direction, and the upper locking claw portion 28A is movable in this direction. That is, the housing members 20 and 30 are assembled with play in these directions, and relative movement within the play range is allowed by the bending of the cable with terminal 40 in the vertical direction.

  As shown in FIG. 2A, a slit-like second holding groove portion 32B is formed in the upper portion of the end wall 32 so as to be parallel to the cable arrangement direction and open upward. As will be described later, the second holding groove portion 32B is configured to hold the second regulating member 70 when the mounting portion 72A of the second regulating member 70 is press-fitted from above.

  As shown in FIG. 2A, the interposition member 50 has a quadrangular ring shape adapted to the step portion 27 of the first housing member 20. In this embodiment, the interposition member 50 has conductivity such as conductive rubber. Made of deformable material. As described above, the interposition member 50 is located between the upper surface of the stepped portion 27 of the first housing member 20 and the upper surface of the receiving recess 37 of the second housing member 30. When the interposition member 50 is clamped in the cable arrangement direction and the connector width direction, the flexibility of the interposition member 50 allows the relative positions of the housing members 20 and 30 to be changed. When sandwiched between the upper surface of the stepped portion 27 and the upper surface of the receiving recess 37 in the vertical direction (longitudinal direction of the housing 10), a reaction force (elastic force) is generated so as to separate the housing members 20 and 30. Thus, the reaction force due to the bending of the cable is compensated.

  Moreover, when the interposition member 50 has conductivity as described above, for example, the housing members 20 and 30 themselves are formed of a conductive material, or the surfaces of the housing members 20 and 30 as necessary. The housing members 20 and 30 can be electrically connected to each other through the interposition member 50 by forming a plating layer having conductivity.

  The first restricting member 60 is made by bending a metal plate member in the plate thickness direction, and has a plate surface perpendicular to the vertical direction as shown in FIG. A restriction plate portion 61 that extends in the direction and a mounting portion 62 that is bent in the plate thickness direction at both longitudinal ends of the restriction plate portion 61 and extends upward. The mounting portion 62 is formed with press-fitting protrusions 62A protruding from both side edges, and the mounting portion 62 is lowered to a slit-like first holding groove portion (not shown) provided at the lower portion of the first housing member 20. The first restricting member 60 is attached to the first housing member 20 by the press-fitting protrusion 62 </ b> A biting into the inner wall surface of the first holding groove portion.

  In the state where the first restriction member 60 is attached to the first housing member 20, the restriction plate portion 61 is the first support portion 26 on both sides in the connector width direction central region on the lower surface of the first housing member 20, that is, the connector width direction. In the area between them, the lower end opening of each first accommodating portion 24 is partially blocked, and the protrusion of the lower end side portion of the cable with terminal 40 outward from the lower end opening is restricted. As a result, the terminal-attached cable 40 is prevented from coming off from the first housing member 20 downward.

  Further, in a state where the first restricting member 60 is attached, the restricting plate portion 61 of the first restricting member 60 is adjacent to the surrounding portion (the cylindrical fitting portion) formed on the outer conductor of the first terminal 42. And a part of the portion surrounding the dielectric) at the same position in the vertical direction (see the second regulating member 70 shown in FIG. 4). As a result, the side end surface (plate thickness surface extending in the cable arrangement direction) of the regulation plate portion 61 is positioned to face the end surface (plate thickness surface) of the surrounding portion with a gap in the connector width direction, The enclosure portion in the width direction of the connector and thus the movement of the first terminal 42 by a predetermined amount or more is restricted. In other words, the first terminal 42 can move within the range of play with the gap as play.

  Moreover, in this embodiment, since the 1st control member 60 is a metal member, the shielding effect is acquired. When the shielding effect is not required, the first regulating member 60 is not necessarily a metal member, and may be made of a material other than metal, such as a resin. Moreover, the 1st control member 60 is not essential if it can control protrusion of the cable 40 with a terminal, for example, may be rod shape extended in a cable arrangement direction.

  The 2nd control member 70 is the completely same structure as the 1st control member 60, and is shown in the attitude | position which turned the 1st control member 60 upside down in FIG. 2 (A). About the 2nd control member 70, the code | symbol which added "10" to the code | symbol in this 1st control member 60 is attached to the same part as the 1st control member 60, and the description is abbreviate | omitted. The second restricting member 70 is attached to the second housing member 30 from above in the same manner as the first restricting member 60, and protrudes upward from the upper end side portion of the terminal-attached cable 40 from the second housing member 30. To regulate. As a result, the upward disconnection of the cable with terminal 40 from the second housing member 30 is prevented.

  Next, the assembly procedure of the relay connector 1 will be described. First, after the interposition member 50 is disposed on the stepped portion 27 of the first housing member 20 from above, the second housing member 30 is attached to the first housing member 20 from above. In the mounting process of the second housing member 30, the upper elastic arm portion 28 of the first housing member 20 is arranged in the cable arrangement direction by the upper locking claw portion 28 </ b> A contacting the lower end of the end wall 32 of the second housing member 30. After the elastic displacement inward, the upper locking claw portion 28A returns to the free state when it reaches the position of the concave strip portion 32A of the second housing member 30, and the upper locking claw portion 28A is returned to the concave strip portion 32A. Enter inside. As a result, the upper locking claw portion 28A is positioned so as to be locked in the vertical direction with respect to the lower end surface of the concave strip portion 32A as a locked surface, so that the housing members 20 and 30 are prevented from coming off each other. In this state, the housing 10 is assembled with play in the vertical direction to complete the housing 10.

  In the state where the housing members 20 and 30 are assembled, the first housing portion 24 of the first housing member 20 and the second housing portion 34 of the second housing member 30 that are in the same position in the cable arrangement direction are connected to the terminal-attached cable. An accommodating portion that accommodates the entire 40 in a bent state is formed over the entire vertical direction of the housing 10.

  Next, the cable with terminal 40A belonging to the first group is inserted from above or below into the housing portion of the housing 10 (see the first housing portion 24A and the second housing portion 34A shown in FIG. 5A). . Then, the lower end side portion and the upper end side portion of the cable with terminal 40 are bent to accommodate the first terminal 42A into the first support portion 26 of the first housing member 20 from the inner side in the connector width direction. The two terminals 43 </ b> A are accommodated in the second support portion 36 of the second housing member 30 from the inner side in the connector width direction. As a result, as shown in FIG. 5A, the terminal-equipped cable 40A having the first terminal 42A and the second terminal 43A at the ends thereof is formed in a substantially inverted S shape within the housing portions 24A and 24B of the housing 10. Housed in a bent state.

  Next, the first terminal 42B and the second terminal 43B of the second group of cables with terminals 40B are placed in the first support portion 26 and the second support of the housing 10 in the same manner as the first group of cables with terminals 40A described above. It accommodates in the part 36, respectively. As a result, as shown in FIG. 5B, the terminal-attached cable 40 </ b> B is housed in a state of being bent in a substantially S shape within the housing portions 24 </ b> B and 34 </ b> B of the housing 10. In this way, the process of attaching the terminal-attached cables 40A and 40B to the housing 10 is completed. The attaching process of the second group of terminal cable 40B may be performed prior to the attaching process of the first group terminal cable 40A or may be performed simultaneously.

  Next, the mounting portion 62 (see FIG. 2A) of the first restricting member 60 is press-fitted into the holding groove portion formed in the end wall 22 of the first housing member 20 from below, and the first restricting member 60 is moved. The first housing member 20 is attached. Further, the mounting portion 72 (see FIG. 2B) of the second restricting member 70 is press-fitted into the second holding groove portion 32B of the end wall 32 of the second housing member 30 from above, so that the second restricting member 70 is The two housing members 30 are attached. In this way, the relay connector 1 is assembled.

[First connection body]
FIG. 3A is a perspective view showing a state before the first connection body 2 is assembled, and FIG. 3B is a perspective view showing a state after the first connection body 2 is assembled. The first connection body 2 is provided on the upper surface (mounting surface) of the first circuit board B1 and is provided on the upper surface of the first circuit board B1. It has a guide member 90 for guiding the housing member 20 to a regular connection position, and a fixture 100 for fixing the guide member 90 to the first circuit board B1.

  The first mating terminal 80 includes a cylindrical metal outer conductor, a metal male center conductor as a first connecting portion located in the outer conductor, and the outer conductor and the male center conductor. And a dielectric body that is integrally held, and is fitted and connected to the first terminal 42 of the relay connector 1. Since the configuration of the first mating terminal 80 itself is known, detailed description thereof is omitted here. The first mating terminal 80 is soldered to a corresponding circuit portion B1A provided on the upper surface of the first circuit board B1 at a position corresponding to each of the plurality of first terminals 42 of the relay connector 1. As a result, they are arranged in a staggered manner at intervals.

  The guide member 90 is made of an electrical insulating material, and has a bottom wall portion 91 and a square frame-shaped peripheral wall portion 92 that rises from the peripheral edge portion of the bottom wall portion 91, and has a bottom with an opening upward. It has a box shape. The bottom wall portion 91 is formed with a rectangular bottom hole portion 91A penetrating in the vertical direction at a position corresponding to each of the plurality of first mating terminals 80 arranged in a staggered manner. The bottom hole portion 91 </ b> A is formed to have a size surrounding the first mating terminal 80 when viewed from above. The space surrounded by the peripheral wall portion 92 is formed as a receiving portion 95 for receiving a plurality of first mating terminals 80 arranged in a staggered manner and receiving the first housing member 20 from above. A guide surface 92 </ b> A is formed on the inner peripheral edge of the upper end surface of the peripheral wall portion 92. The guide surface 92 </ b> A is inclined downward toward the receiving portion 95.

  The peripheral wall portion 92 has a pair of side walls 93 extending in the arrangement direction of the first mating terminals 80 (the same direction as the cable arrangement direction) and a connecting body width direction perpendicular to the arrangement direction (the same direction as the connector width direction). It has a pair of end walls 94 that extend and connect the ends of the pair of side walls 93. The outer wall surface of the end wall 94 is formed with an outer recess 94A that is recessed in the central region in the connecting body width direction and extends in the vertical direction, and the fixing fitting 100 is press-fitted and held in the outer recess 94A. Further, the inner wall surface of the end wall 94 is formed with an inner concave portion 94B that is recessed in both end regions in the connecting body width direction and extends in the vertical direction. The inner recess 94B is configured to receive the lower locking claw portion 29A of the lower elastic arm portion 29 of the relay connector 1 in a connected state of the first connecting body 2 and the relay connector 1 (FIG. 7). reference). Further, the upper end surface (upper inner wall surface) of the inner recess 94B functions as a locked surface for locking the lower locking claw portion 29A in the pulling direction (upward) of the relay connector 1.

  The guide member 90 protrudes inward from the inner wall surface of the side wall 93 toward the receiving portion 95 in the connecting body width direction at the lower half of the side wall 93 between the first mating terminals 80 adjacent to each other in the arrangement direction. A partition wall 96 is provided. The upper surface of the partition wall 96 forms an inclined surface that is inclined downward (toward the bottom wall portion 91) toward the inside of the receiving portion 95, and the inclined surface is formed as a guide surface 96A. The guide surface 96A is configured to reliably guide the first housing member 20 provided in the receiving portion 95 to the normal connection position. In the present embodiment, the partition wall 96 is set higher in the vertical direction than the first mating terminal 80 in a range where the first mating terminal 80 exists in the connecting body width direction. Therefore, the guide surface 96A that forms the upper surface of the partition wall 96 is positioned above the first mating terminal 80 in the above range, and the guide surface 96A allows the lower surface of the first housing member 20 and the first mating terminal 80 to Is prevented and damage to the first mating terminal 80 is prevented.

  The fixing metal fitting 100 is made by bending a metal plate member in the plate thickness direction, and the held portion 101 that extends in the vertical direction along the end wall 94 of the guide member 90 and the lower end of the held portion 101 are described above. And a fixing portion 102 bent outward in the arrangement direction. The held portion 101 has both side edges (vertical direction) in the outer recessed portion 94A of the guide member 90 by opposing inner wall surfaces (two inner wall surfaces facing each other in the connecting body width direction) of the outer recessed portion 94A. The edge extending to the bottom is press-fitted and held.

  The 1st connection body 2 comprised in this way is attached to 1st circuit board B1 in the following ways. First, the first mating terminals 80 are soldered to the corresponding circuit portions B1A arranged in a staggered pattern on the upper surface of the first circuit board B1. Next, the fixing bracket 100 is press-fitted and attached to the outer recess 94A of the guide member 90 from above. Then, the guide member 90 to which the fixing metal fitting 100 is attached is arranged on the first circuit board B1 from above, and the fixing part 102 of the fixing metal fitting 100 is soldered to the corresponding part B1B formed on the upper surface of the first circuit board B1. Connecting. At this time, the first mating terminal 80 enters the corresponding bottom hole portion 91 </ b> A from below as shown in FIG. 3B and is located in the receiving portion 95. In this way, the attachment of the first connection body 2 to the first circuit board B1 is completed.

[Second connection body]
The second connection body 3 (see FIG. 7) attached to the second circuit board B2 has a configuration in which the same thing as the first connection body 2 described above is simply turned upside down, and is attached to the second circuit board B2. The procedure is the same as the procedure for mounting the first connector 2 on the first circuit board B2. About the structure of the 2nd connection body 3, the code | symbol which added "30" to the code | symbol in this 1st connection body 2 is attached | subjected to the part corresponding to each part of the 1st connection body 2, and description is abbreviate | omitted. To do.

  Next, a connection operation between the first connection body 2 and the second connection body 3 via the relay connector 1 will be described. First, as described above, the first mating terminal 80 and the fixture 100 of the first connection body 2 are solder-connected to the corresponding circuit portion B1A and the corresponding portion B1B of the first circuit board B1, respectively, so that the first connection body 2 Is mounted on the mounting surface of the first circuit board B1. Further, the second connection body 3 is mounted on the mounting surface of the second circuit board B2 in the same manner as the first connection body 2.

  Next, as indicated by an arrow in FIG. 1A, the first housing member 20 of the relay connector 1 is fitted into the receiving portion 95 of the peripheral wall portion 92 of the first connector 2 from above. Here, there is a displacement between the relay connector 1 and the first connection body 2 with respect to the normal connection position in the direction parallel to the surface of the first circuit board B1, that is, in the cable arrangement direction and the connector width direction. If it occurs, the relay connector 1 is guided toward the receiving portion 95 with the lower end of the first housing member 20 contacting the guide surface 92A of the peripheral wall portion 92. Furthermore, in the receiving part 95, the relay connector 1 is guided to the regular connection position in the connector width direction with the lower end of the first housing member 20 contacting the guide surface 96A of the partition wall 96. At this time, since the contact between the lower end of the first housing member 20 and the first mating terminal 80 is prevented by the guide surface 96A as described above, damage to the first mating terminal 80 is prevented.

  After the first housing member 20 of the relay connector 1 is brought into the normal fitting position with the first connector 2, the first terminal 42 of the relay connector 1 and the first mating terminal 80 of the first connector 2 Are connected and become electrically conductive.

  Further, in the process of inserting the relay connector 1, the lower locking claw portion 29 </ b> A of the lower elastic arm portion 29 of the first housing member 20 contacts the inner wall surface of the end wall 94 of the peripheral wall portion 92, The elastic arm portion 29 is elastically displaced inward in the cable arrangement direction. When the lower locking claw portion 29A reaches the position of the inner recess 94B of the end wall 94, the lower elastic arm portion 29 returns to the free state, and the lower locking claw portion 29A is moved into the inner recess 94B. It is positioned so as to be able to be locked in the extraction direction (upward) of the relay connector 1 with respect to the upper end surface (locked surface) of the inner recess 94B. As a result, inadvertent disconnection of the relay connector 1 from the first connection body 2 is prevented.

  Next, the second connecting body 3 mounted on the second circuit board B2 is received by the receiving portion 125 (the member having the same configuration as the guide member 90 of the first connecting body 2) of the second connecting body 3 (the member having the same configuration as the guide member 90 of the first connecting body 2). The relay connector 1 is attached from above (see the arrow in FIG. 1A) while maintaining the posture of opening downward (see FIG. 7). That is, the upper part of the second housing member 30 of the relay connector 1 is fitted into the receiving part 125 of the guide member 120 of the second connector 3 from below. In the fitting process, the second housing member 30 is guided to the regular connection position by the guide member 120 and is properly fitted with the second connection body 3 in the same manner as described above for the connection with the first connection body 2. After being brought to the position, the second terminal 43 of the relay connector 1 and the second mating terminal 110 as the second connection portion of the second connector 3 are connected and become electrically conductive (FIG. 7). As a result, as shown in FIG. 1B and FIG. 7, the first connection body 2 and the second connection body 3 are electrically connected via the relay connector 1.

  In this embodiment, the housing 10 is divided into two housing members 20 and 30, and even if there is an error (displacement) in the relative position in the vertical direction between the circuit boards B1 and B2 in use, a terminal is attached. The relative movement between the housing members 20 and 30 is allowed by the bending of the cable 40 in the vertical direction, and the error is absorbed. Even if there is an error (displacement) in the relative position between the circuit boards B1 and B2 in the two directions of the connector arrangement direction and the connector width direction, the housings 20 and 30 are connected to each other by the bending of the terminal cable 40 in these directions. However, the relative movement within the play range described above is allowed, and the error is absorbed. Further, the error in the relative position in the two directions is also absorbed by the movement of the terminals 20 and 30 in the support portions 26 and 36 of the housing members 20 and 30 within the above-described play range. As a result, when absorbing errors (displacement) in the vertical direction, the connector arrangement direction, and the connector width direction, the terminals 42 of the relay connector 1 in a state where no stress is generated in the parts other than the cable 40 with terminals. 43 can be connected to the mating terminals 80 and 110 of the connection bodies 2 and 3 at regular connection positions, respectively.

  In this embodiment, even if the positional relationship between the circuit boards B1 and B2 is periodically changed in three directions of the vertical direction, the cable arrangement direction, and the connector width direction due to vibration or the like in the use state. Since the housing member 20 and 30 are allowed to move relative to each other in the above-described three directions due to the bending of the cable with terminal 40, the terminals 42 and 43 follow the positional fluctuations of the mating terminals 80 and 110, respectively. Therefore, the connection state between the terminals can be favorably maintained without causing sliding contact between the terminals.

  Further, in the present embodiment, among the members constituting the relay connector 1, only the housing 10 is formed separately, and friction due to relative movement as in the conventional case does not occur between components other than the housing 10. . Moreover, since the structure of the connector as a whole is simple and the number of parts is small, it is possible to easily assemble the connector and reduce the cost. In particular, when a large number of terminal-attached cables are provided as in the relay connector of this embodiment, the above-described effect is enhanced.

  In the relay connector 1 according to the present embodiment, a cable 40 with a terminal, which is well known as a component itself, is provided, and the relative movement between the housing members 20 and 30 can be allowed using the bending of the cable 40 with a terminal. Yes. Therefore, since known components can be employed in this way, the relay connector 1 can be manufactured at low cost. In the present embodiment, the cable used for the terminal-attached cable is a coaxial cable. However, instead of the coaxial cable, other types of cables other than the coaxial can be used.

  In the present embodiment, the housing 10 is formed by assembling the two housing members 20 and 30, but the number of housing members is not limited to this, and may be three or more. For example, a third housing member may be provided between the first housing member and the second housing member, and the three housing members may be assembled so as to be capable of relative movement.

  In the present embodiment, the terminals 42 and 43 are provided at both ends of the coaxial cable 41 to configure the cable 40 with a terminal. However, as a modification, a terminal may be provided only at one end of the coaxial cable. Good. In this modified example, one end of the cable with terminal provided with the terminal is connected to the other terminal at the terminal, and the other end not provided with the terminal is directly solder-connected to the corresponding circuit portion of the circuit board.

  In the present embodiment, the terminal-attached cable 40 is accommodated in the housing 10 in a bent state. However, as a modification, the terminal-attached cable 40 may be accommodated in the housing in an unbent state. Even in this modification, for example, when the distance between the circuit boards in the vertical direction is smaller than the set value, the relative movement between the housing members is allowed by the bending of the cable with the terminal so that the relative position error may occur. Can be absorbed.

  In the present embodiment, the connection bodies 2 and 3 connected to the relay connector 1 have the guide member 90 and the mating terminals 80 and 110 separately. However, as a modification, the connection body is a housing. It may be configured as an electrical connector in which a mating terminal is held by a guide member.

<Second embodiment>
In the first embodiment, the form in which two circuit boards whose mounting surfaces are parallel to each other is electrically connected has been described. However, the present invention can be implemented by, for example, mounting a circuit board as in the second embodiment described below. The present invention can also be applied to a so-called right angle connection in which the surfaces form a right angle.

  8A and 8B are perspective cross-sectional views showing a cross section of the relay connector 1 ′ according to the second embodiment at a plane perpendicular to the cable arrangement direction, and FIG. FIG. 8B shows a cross-section at the position of the second group of terminal-equipped cables 40B ′. In FIG. 8, portions corresponding to the respective portions in the first embodiment are indicated by adding “′” to the reference numerals in the first embodiment, and description of portions having the same shape as in the first embodiment is omitted. .

  In the second embodiment, the mounting surfaces of the first circuit board B1 ′ and the second circuit board (not shown) are perpendicular to each other. In this respect, the first circuit board B1 and the second circuit board B2 This is different from the first embodiment (see FIGS. 1A and 1B) in which the mounting surfaces are parallel to each other. In the relay connector 1 according to the second embodiment, the housing 10 ′ includes a first housing member 20 ′ and a second housing member 30 ′ that are perpendicular to each other in the connection direction with respect to the circuit board. They are assembled in a state extending in a substantially horizontal L shape when viewed in the cable arrangement direction.

  As seen in FIGS. 8A and 8B, the first housing member 20 ′ has substantially the same shape as the first housing member 20 of the first embodiment, but the second housing member 30 ′ is the first embodiment. The shape is such that the second housing member 30 of the form is tilted sideways. The second housing member 30 ′ is formed with an opening directed downward in the side wall 31 ′ located on the lower side of the two side walls 31 ′ opposed in the vertical direction, and the first housing member 20 ′ By being inserted from below through the opening, it is assembled to the second housing member 30 ′ via the interposition member 50 ′.

  The terminal-attached cable 40 ′ is housed in a bent state while extending in a substantially horizontal L shape within the housing portions 24 ′ and 34 ′ of the housing 10 ′. Both housing members 20 ′ and 30 ′ are assembled with play in three directions, ie, the vertical direction, the cable arrangement direction, and the connector width direction, and within the range of play in the three directions due to the bending of the cable with terminal 40 ′. Relative movement is possible. As a result, errors (shifts) in the relative positions of the circuit boards in the three directions are absorbed.
