Description
Technical Field
The present invention relates to an electrical relay for electrically connecting an electrical connector to a connection target.
Background
Such an electrical relay is disclosed in patent document 1 as an intermediate connector used for an electrical connector assembly. The intermediate connector of patent document 1 includes 2 conductive terminals arranged in a housing, and each of the conductive terminals is configured such that a cylindrical first contact portion on one end side is connected to a cylindrical second contact portion on the other end side by a connection portion. The axis of the first contact portion and the axis of the second contact portion are in a perpendicular positional relationship, the connecting portion is in the form of a metal strip plate and is bent in the plate thickness direction, and the first contact portion and the second contact portion, the axes of which are perpendicular to each other, are connected. The first mounting connector of the opposite side connected with the first contact part is mounted on one circuit substrate, and the second mounting connector of the opposite side connected with the second contact part is mounted on the other circuit substrate.
The first mounting connector and the second mounting connector respectively hold elastic cylindrical members in holding holes formed in the housing. The elastic cylindrical member is formed in a cylindrical shape for receiving the first or second contact portion of the conductive terminal in the axial direction, and has a plurality of slits extending in the axial direction distributed in the circumferential direction except for the axial end portions, and an annular constricted portion having a reduced diameter at the axial middle portion.
When the first contact portion is inserted into the elastic cylindrical member of the first mounting connector and the second contact member is inserted into the elastic cylindrical member of the second mounting member, the annular constricted portion of each elastic cylindrical member is elastically expanded by the first contact portion or the second contact portion, a contact pressure is generated between the annular constricted portion and the first contact portion or the second contact portion, and the first contact portion or the second contact portion can be tilted with respect to each axis about the annular constricted portion as a fulcrum, thereby providing a floating characteristic.
Patent document 1: japanese laid-open patent publication No. 2014-120377
In patent document 1, the first contact portion and the second contact portion provided on the conductive terminals of the intermediate connector are rotatable relative to the first mounting connector and the second mounting connector about the respective axes, and the inclination with respect to the axes is allowed according to the floating characteristic, but the allowable amount of the inclination is small. In this inclination, the first contact portion or the second contact portion is supported with the minimum inner diameter portion, which is the annular constricted portion, as a fulcrum in a state where the elastic cylindrical member is elastically deformable in the radial direction, and therefore, the inclination can be made to be an inclination centered on the fulcrum and within an elastically deformable amount. As a result, the allowable inclination angle is small, and it is possible to cope with the degree of mounting error between the intermediate connector and the first and second mounting connectors, but it is impossible to cope with, for example, a change in the mounting position.
Disclosure of Invention
In view of such circumstances, an object of the present invention is to provide an electrical relay that can allow a large inclination of a connection member with respect to a contact member.
The electric relay according to the present invention comprises: the connector includes a metal contact member having a columnar shape extending in one axial direction, and a metal connecting member electrically connected to the metal contact member, the metal contact member being inserted into and connected to a target connector in the axial direction of the metal contact member, and the metal connecting member being connected to a connection target of the metal connecting member.
In the above-described electric relay, in the present invention, the contact member has a cylindrical shape in which one end side is relatively rotatable about an axis of the contact member with respect to the target connector, and a swinging structure which is swingable relative to each other is formed by the other end side of the contact member and the one end side of the connection member, and the swinging structure is a structure in which the contact member and the connection member are supported by each other so that the contact member and the connection member are relatively swingable about another axis orthogonal to the axis of the contact member and an axis from the one end side of the connection member toward the other end side.
According to the present invention having such a configuration, since the one end side of the contact member is cylindrical, the contact member can be rotated about the axis of the contact member in a state of being inserted and connected to the target connector, and the connection portion connecting the contact member and the connection member can be swung about the other axis, so that a degree of freedom about 2 axes in total can be obtained. Therefore, the target connector and the connection target are relayed by the electric relay in a state where the position and the direction of the contact member, and thus the connection member, can be changed over a wide range.
In the present invention, the swinging structure may be configured such that the ring plate portion provided on the other end side of the contact member and the other ring plate portion provided on the one end side of the connection member are swingably connected by a connection member extending along the other axis.
With this configuration, the 2 ring plate portions can be supported by the coupling member so as to be swingable about the other axis, and can also be downsized in the other axis direction, with a simple structure.
In the present invention, the connecting member may include, depending on a design condition of a device using the electric relay body, a portion extending from one end side to the other end side of the connecting member: at least one of the columnar member and the flexible cable member.
In the present invention, when there is a degree of freedom in the design conditions of the device using the electric relay, the contact member and the connection member can be in the same form.
This reduces the number of types of components forming the electrical relay, and improves the management of components and the reduction of production cost.
In the present invention, at least the contact member of the contact member and the connection member can be held by the housing. In this way, the electrical relay can be protected, and the connection work of the contact member to the target connector and the connection work of the connection member to the connection target can be performed safely and easily.
In the present invention, as described above, the electric relay has a structure in which the contact member and the connection member are coupled to each other and are swingable about the other axis orthogonal to the axis of the contact member and the axis of the connection member, and therefore, in addition to the contact member having a cylindrical one end side being rotatable about its axis with respect to the counterpart connector, the connection member can be relatively swung about the other axis with respect to the contact member, a large inclination of the connection member with respect to the contact member is allowed, and a large degree of freedom is obtained about 2 axes.

Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Fig. 1 is a perspective view showing an appearance of an electric relay 10 according to an embodiment of the present invention before the electric relay is connected to a mating connector 60 to be connected to one of the electric relays 10. In fig. 1, the other connection target of the electrical relay 10 is not shown.
The electric relay 10 shown in fig. 1 is supported by the housing 50, and is connected to an elastic cylindrical member 61 of the mating connector 60, which is a contact supported by the mating housing 70.
The housing 50 is provided with 2 electric relays 10 supported in pairs, and the two electric relays 10 are manufactured in the same manner, and are arranged in a symmetrical manner in the facing direction in fig. 1.
As can be seen from fig. 2, which shows the respective components separately, the electrical relay 10 has: a contact member 20 to one end side of which an object connector 60 as one connection object is electrically connected; a connecting member 30 electrically connected to the other connection object not shown; and a rivet-shaped coupling member 40 that rotatably couples the two members, and a swing structure S is formed by the coupling member 40 and the other end side of the contact member 20 and one end side of the coupling member 30 shown in fig. 2.
The contact member 20 is manufactured by processing a metal plate member having a band-shaped portion, and has: a cylindrical portion 21 that makes the band-shaped portion circular into a cylindrical shape with its longitudinal direction as an axis; a pair of locking pieces 22 that are arranged and projected radially outward with respect to the columnar portion 21 at the upper end of the columnar portion 21; and a ring plate portion 23 extending from the cylindrical portion 21 in the axial direction and having a diameter in the axial direction. The cylindrical portion 21 is slightly reduced in diameter at the lower end portion, and can easily enter the elastic cylindrical member 61 of the mating connector 60 with a contact pressure. The pair of locking pieces 22 come into contact with the locking step of the housing 50 when the contact member 20 is inserted into and assembled with the housing 50 in the axial direction thereof, and define the axial position of the contact member 20. The ring plate portion 23 is formed with a hole portion 23A through which a post portion 42 of a connecting member 40 described later passes.
The connecting member 30 has: a cable 31 connected to the other connection target not shown; and a metal member 32 that grips the core wire 31B, the core wire 31B being exposed by the sheath 31A of the cable 31 being removed at the front end portion. The metal fitting 32 is manufactured by processing a metal plate, and includes a clamp portion 33 for clamping the core wire 31B, and a ring plate portion 34 extending from the clamp portion 33.
The clamp 33 has a C-shaped cross section perpendicular to the axis of the cable 31, and the distal ends thereof are crushed so as to approach each other, whereby the distal ends of the clamp 33 clamp the core wires 31B of the cable 31. The annular plate portion 34 extending from the clamp portion 33 has an outer diameter almost equal to that of the annular plate portion 23 of the contact member 20, and a hole portion 34A having an inner diameter almost equal to that of the hole portion 23A of the annular plate portion 23 of the contact member 20 is formed.
In the present embodiment, the connecting member 40 is formed as a metal rivet and has a disk-shaped head portion 41 and a column portion 42. The column part 42 has an outer diameter slightly smaller than the hole 23A formed in the annular plate part 23 of the contact member 20 and the hole 34A formed in the annular plate part 34 of the connection member 30. In the present embodiment, the coupling member 40 is used together with a disc spring 43 having a conical disc shape and having a hole 43A with a slightly larger inner diameter than the column portion 42.
In the above-described connecting member 40, the column portion 42 of the connecting member 40 penetrates the hole portion 43A of the coil spring 43, the hole portion 34A of the annular plate portion 34 of the connecting member 30, and the hole portion 23A of the annular plate portion 23 of the contact member 20 in this order, and then the front end (left end in fig. 4) of the column portion 42 is crushed as seen in fig. 4, so that the swinging structure S between the connecting member 30 and the contact member 20 is formed such that the connecting member 30 can swing freely about the column portion 42 with respect to the contact member 20. At this time, the coil spring 43 is in a compressed state, and a contact pressure is generated between the ring plate portion 34 of the connecting member 30 and the ring plate portion 23 of the contact member 20 by the compression elastic force.
The housing 50 is made of an electrically insulating material, and holds 2 electrical relays 10 obtained by coupling and assembling the respective members of fig. 2. At this time, as described above, the 2 electrical relay devices 10 are arranged and juxtaposed in a posture symmetrical to each other as seen in fig. 1. The 2 electrical relay bodies 10 are present in a direction in which the locking pieces 22 are separated from each other in the facing direction of the 2 electrical relay bodies 10.
As shown in fig. 1, the housing 50 has a substantially cubic outer shape, and supports the electric relay 10 such that the electric relay 10 is positioned on both sides of the partitioning protrusion 51 protruding upward. As can be seen from fig. 5 (a), the housing 50 has recesses 52A, 52B formed in the upper and lower portions, and a thicker intermediate wall 53 between the recesses 52A, 52B has a support hole 53A into which the cylindrical portion 21 of the contact member 20 is inserted.
Although not shown in fig. 5, when the columnar portion 21 is inserted to a predetermined position in the intermediate wall 53, a locking step portion, with which the pair of locking pieces 22 protruding from the columnar portion 21 abut, is formed so as to be connected to an upper portion of the support hole 53A in a direction perpendicular to the paper surface in fig. 5. The support hole 53A and the locking step are symmetrical with respect to 2 electric relays 10.
The recess 52B formed in the lower portion of the housing 50 is configured to accommodate a fitting projection 72A, which will be described later, formed in the housing 70 of the mating connector 60, which will be described later.
In the case where the housing 50 supports 2 electrical relays 10, both electrical relays 10 can be fitted and connected to the mating connector 60 by one operation, but in the present invention, the housing 50 is not essential, and 2 electrical relays 10 not supported by the housing 50 can be connected to the mating connector 60 independently.
Next, as can be seen in fig. 1, the object connector 60 has: a metal elastic cylindrical member 61 serving as a terminal, an object case 70 made of an electrically insulating material for supporting the elastic cylindrical member 61, and a mounting metal fitting 80 supported by the object case 70 and fixedly mounted on a circuit board (not shown).
After a slit band-shaped plate in which a plurality of fine slits are formed in parallel at intervals in a relatively thin metal plate is obtained as a semi-finished member, the slit band-shaped plate is cylindrically deformed and circumferential ends are joined to each other so that the longitudinal direction of the slits becomes the axial direction, and then, a diameter reduction process is performed so that the diameter of the cylindrical body is reduced at the center position in the axial direction, thereby obtaining the elastic cylindrical member 61. As shown in fig. 5 (a) and (B), the elastic cylindrical member 61 thus obtained has a plurality of slits 61A extending in the axial direction formed at a plurality of positions in the circumferential direction, annular end portions 61B having no slits at both ends in the axial direction, and a reduced diameter portion 61C formed at a substantially central position in the same direction and having elasticity in the radial direction due to the presence of the slits 61A in the range in the axial direction in which the slits 61A are formed. The inner diameter of the reduced diameter portion 61C is slightly smaller than the outer diameter of the columnar portion 21 of the contact member 20 in a free state in which no external force is applied, and when the columnar portion 21 is inserted into the reduced diameter portion 61C, the reduced diameter portion 61C is pressed radially outward by the columnar portion 21 and elastically expanded in diameter, and generates a contact pressure with the columnar portion 21 and supports the columnar portion 21. The columnar portion 21 is in contact with the reduced diameter portion 61C only in a narrow range in the axial direction, is rotatable around the axis in the elastic cylindrical member 61, and is slightly tiltable with the reduced diameter portion 61C as a fulcrum.
Although not shown, the elastic cylindrical member 61 integrally has a connection leg electrically connected to the circuit board, or is electrically connected to a separate connection leg.
The object housing 70 of the object connector 60 includes: an upper case 72 provided with a fitting projection 72A, the fitting projection 72A being fitted into a recess 52B formed in a lower portion of the case 50 accommodating the contact member 20; and 2 lower cases 73 assembled to the upper case 72.
As shown in fig. 1, the upper case 72 has a fitting projection 72A having a substantially rectangular parallelepiped outer shape and a flange portion 72B projecting from a lower portion of the fitting projection 72A to the periphery, and a positioning projection 72A-1 is provided on a side surface of the fitting projection 72A so as to project laterally.
When entering the recess 52B of the housing 50, the flange 72B abuts against the bottom surface of the housing 50 and is determined to enter a predetermined position, and the positioning protrusion 72A-1 is fitted into the positioning recess 54 (see fig. 1) formed in the side wall of the housing 50 for positioning and holds the mounting metal fitting 80 for mounting the object housing 70 on the circuit board. As shown in fig. 1, the attachment fitting 80 is a plate-like member that is press-fitted from above into the slit 72A-2 formed in the positioning protrusion 72A-1, and the lower end side of the attachment fitting 80 protrudes downward from the lower surface of the positioning protrusion 72A-1.
In the upper case 72, through holes 74 corresponding to the contact members 21 of the 2 electrical relays 10 are formed in the fitting projection 72A so as to vertically penetrate at two locations. As can be seen from fig. 5, each through hole 74 has an appropriate hole diameter and hole length for inserting a lower case 73, which will be described later, in which the elastic cylindrical member 61 is housed from below, and an upper step portion 74A for regulating the upper position of the lower case 73 is provided at the upper portion.
As shown in fig. 5 (a), the lower case 73 inserted into each through hole 74 is a bottomed cylindrical body, a terminal hole 73A opened upward is formed, and the elastic cylindrical member 61 as a terminal is housed in the terminal hole 73A from above. An annular projection 73B is provided on the outer peripheral surface of the lower case 73, the annular projection 73B defines an insertion position when the upper half of the lower case 73 is inserted into the through hole 74, and the annular projection 73B abuts against the lower surface of the upper case 72 to define an insertion position when the upper half of the lower case 73 is inserted into the through hole 74. Therefore, the lower half of the lower case 73, i.e., the portion below the annular protrusion 73B, protrudes downward from the upper case 72.
In such a lower housing 73, the upper half portion of the lower housing 73 is inserted into the corresponding through hole 74 in a state where the elastic cylindrical member 61 is accommodated in each terminal hole 73A, and is integrally assembled with the upper housing 72 to form the mating connector 60.
The mating connector 60 is disposed on a circuit board (not shown). A hole (not shown) allowing the lower case 73 to enter and a slit (not shown) allowing the lower end portion of the mounting metal fitting 80 attached to the upper case 72 to enter are formed in the circuit board, and the lower end portion of the mounting metal fitting 80 is soldered and fixed to a corresponding portion of the circuit board in a state where the lower case 73 enters the hole of the circuit board and the lower end portion of the mounting metal fitting 80 enters the slit, whereby the target connector 60 is fixed to a predetermined position of the circuit board.
The electrical relay 10 is used and operated in the following manner. In the present embodiment illustrated in fig. 1, the electric relay 10 is used in a state in which 2 electric relays are paired and supported by the housing 50 to form a unit. As shown in fig. 1, the 2 electrical relays 10 are supported by the housing 50 in a posture symmetrical in the opposing direction, and in use, in a state of being supported by the housing 50, brought to a position directly above the mating connector 60, lowered as they are, and fitted into the recess 52B formed in the lower portion of the housing 50 and accommodated in the fitting projection 72A of the upper housing 72 of the mating housing 70 of the mating connector 60.
When the fitting projection 72A of the mating connector 60 is received in the recess 52B of the housing 50, the contact member 21 of the electrical relay 10 projecting downward from the housing 50 enters the elastic cylindrical member 61 of the mating connector 60. The contact member 21 is cylindrical and has a diameter slightly larger than the diameter-reduced portion 61C of the elastic cylindrical member 61, and therefore, in a state where the diameter of the diameter-reduced portion 61 is expanded and the elastic contact pressure is applied, the contact member can rotate around the axis, and can be slightly inclined with the diameter-reduced portion 61 as a fulcrum and also can be displaced in the radial direction.
The connecting member 30 connected to the contact member 21 so as to be able to swing is connected to a connection target (not shown) after or before the housing 50 is fitted to the target connector 60.
The connecting member 30 and the contact member 20 are connected by the connecting member 40 to form the swing structure S, and as shown by the two-dot chain line in fig. 3, the connecting member 30 can swing about the axis of the connecting member 40 with respect to the contact member 20, allowing a large inclination of the connecting member 30 with respect to the contact member 20. Further, since the contact member 20 is rotatable about its axis as described above, the connecting member 30 can change its direction with a large degree of freedom about the axis of the connecting member 40 and further about the axis of the contact member 20, and therefore, even if the position of the connection target of the connecting member 30 is not determined, the position can be followed.
In the present embodiment, the connecting member 30 is not limited to the configuration of the cable 31 and the metal fitting 32 for clamping the core wire of the cable 31 as shown in fig. 1 to 5, and may have the same configuration as the contact member 20. In fig. 6, the contact member 20 and the connection member 30 have the same structure and are connected to each other by the connection member 40 so as to be able to swing. In the connecting member 30 in fig. 6, the same reference numerals are given to portions common to the connecting member 30 in fig. 2, and the columnar portion is newly given "35" and the locking piece is given "36" except for portions common to the contact member 20 in fig. 2. If the contact member 20 and the connection member 30 have the same structure as shown in fig. 6, the electric relay 10 can be simplified in structure by sharing the components.
The present invention is not limited to the use of the electric relay supported by the housing as shown in fig. 1 and 5, and may be used by being directly connected to the mating connector without the housing. Further, depending on the number of terminals (elastic cylindrical bodies) of the mating connector, the connector can be used as a single electrical relay, and can also be used as two or more electrical relays.
