Description

Technical Field

[0001] This disclosure relates to the connection structure of the connector. Background Technology

[0002] As with existing technologies for connector assemblies, such as Patent Document 1 (Japanese Patent Application Publication No. 2024-4140), there are techniques that reduce manufacturing costs and miniaturize the product through structural simplification. Figure 1 , Figure 2 A diagram illustrating the structure of a connector assembly in the prior art. Figure 1 , Figure 2 In the connector assembly, connector assembly 10 includes a first connector 12 and a second connector 14. The first connector 12 has a first terminal fitting 16 protruding outward from a metal frame 20 and a metal cover 22 surrounding the first terminal fitting 16 and protruding from the frame 20. The second connector 14 has a second terminal fitting 18 connected to the first terminal fitting 16, an insulating housing 74 housing the second terminal fitting 18, and a metal plate portion 76 fixedly disposed on the outer surface of the housing 74. In the mating state of the first connector 12 and the second connector 14, the housing 74 of the second connector 14 is housed within the cover 22 of the first connector 12, a contact portion 156 of the plate portion 76 is placed and connected to the protruding end face 64 of the cover 22, and the protruding side opening 58 of the cover 22 is covered by the plate portion 76. Summary of the Invention

[0003] In the connector assembly of Patent Document 1, with the first connector 12 and the second connector 14 engaged, the fastening bolt 190 is inserted to fix the first connector 12 and the second connector 14 to each other (paragraph 0074). Furthermore, in this connector assembly, the conduction between the first connector 12 and the second connector 14 makes each first terminal accessory 16 and each second terminal accessory 18 electrically conductive (paragraph 0073). Here, the second terminal accessory 18 is configured to include a second terminal accessory body 86 and a spring clip 88, which serves as an elastic member, mounted on the front end (front end) of the second terminal accessory body 86 (paragraph 0040). That is, the connector assembly of Patent Document 1 employs a structure where the fastening bolt 190 is inserted and engaged, and conduction is achieved through the spring clip 88. For example, as a connection structure oriented towards high current, besides increasing the number of parts, it also suffers from insufficient contact strength.

[0004] In view of the above-mentioned issues, the present disclosure aims to provide a connector that can suppress the increase in the number of parts and achieve a connection that can withstand large currents.

[0005] To address the aforementioned issues, the connector in this embodiment is a connector consisting of a head and a plug harness that engages with the head. The head has a first housing made of insulating material, a pair of first terminals, a first pressing member made of insulating material, and a nut. The first housing has a pair of through-holes arranged in parallel, and a first bolt insertion portion arranged parallel to the pair of first holes between them. Each first terminal has a first contact surface at one end and a flat, first contact portion capable of being inserted into each of the first holes from the first contact surface side. The first pressing member has a pair of first pressing portions, a connecting portion, and a nut insertion portion. In a first state where the first terminals are respectively inserted into each of the first holes from the first contact surface, the pair of first pressing portions are used to press the first terminals from the side opposite to the first contact surface towards the first contact surface side. The connecting portion connects to the first pressing portions, and the nut insertion portion is provided on the connecting portion. The nut consists of a nut portion and a metal flange portion. The nut portion has a first end portion that inserts into the nut insertion portion from the side opposite to the side pressed by the first pressing portion, and a second end portion opposite to the first end portion. The metal flange portion is fixed to the second end portion and engages with a predetermined portion of the first housing, thereby pressing the connecting portion from the side opposite to the side pressed by the first pressing portion. The plug harness includes a second housing made of insulating material that can be fitted into the first housing, a pair of second terminals, and a metal second pressing member. The second housing has a pair of second holes, at least a portion of which are parallel to the first contact surface when the plug harness is fitted into the head, an opening including a portion of each of the second holes and opening in a direction intersecting the direction of the holes of the second holes, and a second bolt insertion portion arranged parallel to the first axis between the pair of second holes. The second terminals have a flat second contact portion at one end that can be inserted into each of the second holes. The second pressing member has a second pressing portion for pressing a predetermined area of ​​the outer surface of the second housing and the first surface having the second bolt insertion portion in one direction, and a third bolt insertion portion passing through the second pressing portion. The positional relationship between the nut portion and the first to third bolt insertion portions is as follows: In the first state, a pair of first pressing portions are capable of pressing each of the first terminals. In the second state, when a pair of second terminals are respectively inserted into a pair of second holes, and each of the first holes and openings is fitted into the first and second housings respectively, and the second pressing portion of the second pressing member is mounted on a predetermined area, so that each of the first pressing portions of the first pressing member can abut against the surface of the first terminal opposite to the first contact surface, the positional relationship is such that a bolt can be inserted to tighten the bolt and nut. The tightening of the bolt and nut makes each of the first contact portions and each of the second contact portions conductive.

Figure 3 , Figure 2 As shown, the connector 1A in this embodiment consists of a head 2A and a plug harness 3A that fits into the head 2A.

[0026] <Head 2A>

[0027] Figure 8 This is a diagram representing the head 2A, where A is a perspective view, B is a top view, and C is a left side view. Figure 9 yes Figure 8 The FF cross-section of C. (See diagram below.) Figure 4 , Figure 8 As shown, the head 2A includes a first housing 10A, a pair of first terminals 20A, a first pressing member 30A, a gate member 90A, an elastic member 100A, a first sealing member 111A, a second sealing member 112A, and a nut 40A. In this embodiment, the head 2A has four sets of bolts 85A and collars 113A for engaging with other components or products (not shown), such as a substrate. However, the head 2A may also be structured without bolts 85A and collars 113A.

[0028] (First shell 10A)

[0029] Figure 10This is a diagram showing the first housing 10A. A is a top view, B is a QQ section view of A, C is a RR section view of A, and D is a PP section view of A.

[0030] like Figure 9 As shown, the first housing 10A houses the first terminal 20A, the first pressing member 30A, the gate member 90A, the elastic member 100A, and the nut 40A, positioning at least a portion of each component. When the first pressing member 30A is inserted into the first housing 10A, as... Figure 7 As shown, protrusion 20Ad engages with protrusion 10Aj. Thus, a pair of first terminals 20A, gate component 90A, elastic component 100A, and first pressing component 30A are held within the first housing 10A. The first housing 10A is formed, for example, of an insulating material such as resin. In this example, as... Figure 10 As shown, it has: a base 10Ac, which is based on an approximately octagonal rectangular cross-section; and a flange 10Ad, which extends from the lower end side of the base 10Ac ( Figure 10 The end side in the -z direction extends outward in the direction of expanding the cross-sectional area of ​​the octagonal rectangle, forming a rounded quadrilateral shape.

[0031] The base 10Ac has a peripheral wall 10Af, which is formed such that the upper surface 10Ac1 is on the back side ( Figure 10 A portion of the edge (on the -x direction side) is open and stands upright, surrounding the other edges. The base 10Ac has: a pair of first holes 10Aa in a rectangular hole shape, which, within the region surrounded by the peripheral wall 10Af, are in the vertical direction (…). Figure 10 The first bolt insertion portion 10Ab is arranged parallel to the pair of first holes 10Aa between them, allowing the bolt 80A to be inserted. On the upper surface 10Ac1, around the edge of each first hole 10Aa, there are openings extending upwards from the first hole 10Aa. Figure 10 The gate cover 10Ae is installed in an upright manner (in the +z direction). The gate cover 10Ae has a cover over the first contact portion 20Aa ( Figure 9 The shape around the front end side of the ). On the upper surface 10Ac1, around the end of the first bolt insertion part 10Ab, so as to extend from the first bolt insertion part 10Ab along the upper ( Figure 10 A boss 10Ag is formed in the +z direction. The size of the hole in the first bolt insertion part 10Ab, including the size of the hole in the boss 10Ag, has a diameter d1 at the entrance of the hole in the boss 10Ag that is slightly larger than the diameter of the bolt 80A. In the direction of entering the interior (… Figure 10 In the -z direction, it has a diameter d2 that is slightly larger than the diameter of the elastic member 100A, and if it goes further inside, it has a width W ( Figure 10 D), length L ( Figure 10 The rectangular cross-section of hole B) is formed to connect with the first hole 10Aa. A pair of protrusions 10Ak are formed on the outside of the hole shape for engaging with the locking arm 40Aa2 of nut 40A. The upper surface 10Ac1 has a pair of holes 10Ai between each gate cover 10Ae and the protrusion 10Ag, through which the rib 90Ad of gate component 90A can be inserted.

[0032] like Figure 10 As shown in Figure A, the flange portion 10Ad has a collar 113A that can be inserted into it by riveting near the four rounded corners. Figure 4 The collar 113A is formed of a metal such as stainless steel, and bolts 85A can be inserted into the various holes 10Ah in which the collar 113A is installed. Figure 8 ).

[0033] (First terminal 20A)

[0034] like Figure 4 , Figure 6 As shown, the first terminal 20A is a conductive plate having a first contact portion 20Aa and an extension portion 20Ab connected to the first contact portion 20Aa. In this example, the first terminal 20A is formed of copper.

[0035] exist Figure 6 From the perspective of the first contact portion 20Aa, it is an octagonal flat plate with corners that are roughly rectangular and lack longitudinal length, on the upper side (the side of the second contact portion 61Aa). Figure 6 The end portion 20Aa (on the +z direction side) has a first contact surface 20Ac. The first contact portion 20Aa has a first hole portion 10Aa (which can be inserted from the first contact surface 20Ac side) Figure 10 The flat shape of ). Here, in Figure 6 From a visual perspective, the first contact portion 20Aa can be roughly divided into three equal parts from top to bottom: an upper section, a middle section, and a lower section. The area corresponding to the middle section is called the connecting portion 20Ai. The upper and lower sections of the first contact portion 20Aa are connected along... Figure 4 The connection portion 20Ai is configured to extend in the z-axis direction (i.e., the insertion direction of the nut insertion portion 30Ab, the first bolt insertion portion 10Ab, and the fourth bolt insertion portion 90Ab). In this example, the connection portion 20Ai is configured to connect the upper and lower sections in such a way that the lower section is located at an outward offset position relative to the upper section.

[0036] The first contact portion 20Aa has a generally horizontally elongated rectangular hole 20Ae at the center of the connecting portion 20Ai, into which the first pressing member 30Aa is inserted. Both ends of the hole 20Ae in the longitudinal direction are cut out in a manner that widens the hole shape towards the first contact surface 20Ac. When the first pressing member 30Aa is inserted into the hole 20Ae, the first contact portion 20Aa is in an upright position relative to the first pressing member 30A. When the connecting body 1A is assembled, the first contact portion 20Aa is located slightly above the center of the surface corresponding to the outer side (on the side of the second contact portion 61Aa). Figure 6 The +z direction side) has a protrusion 20Ad ( Figure 4 ). The protrusion 20Ad has a downward ( Figure 4 The portion of the first terminal 20A with the protrusion 20Ad travels in the -z direction, and the plate thickness of the portion of the first terminal 20A gradually increases, forming a generally trapezoidal cross-sectional shape. In this example, the protrusion 20Ad is formed by stamping, and a recess is formed on the surface opposite to the surface where the protrusion 20Ad is formed, at a position opposite to the protrusion 20Ad. By making the first terminal 20A have the protrusion 20Ad, the first terminal 20A and the protrusion 10Aj (in the first hole 10Aa of the first housing 10A) are connected. Figure 10 D) engages and remains in the first housing 10A (refer to D) Figure 7 ).

[0037] The extension 20Ab extends from the lower end of the first contact portion 20Aa ( Figure 6 The end on the -z direction side) is oriented downwards (away from the second contact portion 61Aa) in a manner that maintains the width of its lower end. Figure 6 The extension is set in the -z direction. In this example, the extension 20Ab is located slightly above its central end (on the side of the first contact portion 20Aa). Figure 6 The +z direction side has a hole 20Ag that can be used to combine with other components or products (not shown).

[0038] (First pressing component 30A)

[0039] The first pressing member 30A is a plate composed of an insulating member having a thin rectangular parallelepiped shape. In this example, the first pressing member 30A is formed of glass epoxy resin. However, it can also be composed of a separator structure of glass epoxy resin and stainless steel, for example, provided that insulation can be ensured. Figure 4 As shown, the first pressing member 30A has a longitudinal direction ( Figure 4The region on both ends of the first pressing part 30Aa in the y-axis direction) and the connecting part 30Ac connecting the pair of first pressing parts 30Aa. A nut insertion part 30Ab is provided in the center of the connecting part 30Ac, through which the nut part 40Ab of the nut 40A is inserted. The first pressing part 30A inserts each first terminal 20A from the first contact surface 20Ac into each first hole 10Aa ( Figure 10 In the first state, each first terminal 20A is moved from the side opposite to the first contact surface 20Ac. Figure 6 Press the surface 20Ae1) towards the first contact surface 20Ac. It should be noted that when the head 2A is assembled, the nut insertion part 30Ab of the nut insertion part 40Ab is configured to be opposite to the fourth bolt insertion part 90Ab.

[0040] Furthermore, the first pressing member 30A can also be used in other ways as long as it can press the first terminal 20A from the side opposite to the first contact surface 20Ac towards the first contact surface 20Ac. In this case, the nut 40A can continue to press the first pressing member 30A, etc., and other components can be appropriately adjusted in shape.

[0041] (Gate component 90A)

[0042] like Figure 4 As shown, the gate component 90A is an insulating component having a pair of gate portions 90Aa, a connecting portion 90Ac connecting the pair of gate portions 90Aa, and a fourth bolt insertion portion 90Ab in the shape of a boss located at the center of the connecting portion 90Ac, through which a bolt 80A can be inserted. In this example, the gate component 90A is formed of resin.

[0043] The gate section 90Aa has a vertical direction capable of allowing the insertion movement of the first terminal 20A. Figure 4 It has a hollow, box-like shape with an opening in the z-axis direction. The gate portion 90Aa has a shape that covers the periphery of the front end side of the first contact portion 20Aa. In other words, a pair of gate portions 90Aa cover the periphery of one end of each of the pair of first contact portions 20Aa in a state where the end is exposed.

[0044] like Figure 9 As shown, in order to more firmly support the gate part 90Aa and the fourth bolt insertion part 90Ab, the gate component 90A has a pair of ribs 90Ad on the connecting part 90Ac.

[0045] Regarding the shape of the internal hole of the fourth bolt insertion part 90Ab, the inlet has a diameter slightly larger than that of the bolt 80A, and its internal diameter is formed in the shape of a hole with a diameter d3 slightly larger than that of the elastic member 100A, so that the elastic member 100A can be inserted.

[0046] (Elastic component 100A)

[0047] like Figure 9 As shown, the elastic member 100A of this embodiment has the shape of a helical spring. In this example, the elastic member 100A is made of stainless steel. The inner diameter of the elastic member 100A has a diameter slightly larger than that of the bolt 80A, so that the bolt 80A can be inserted through. One end of the elastic member 100A is mounted on the nut insertion portion 30Ab of the first pressing member 30A. The other end is inserted into the interior of the fourth bolt insertion portion 90Ab. Thus, when assembling the head 2A, at least a portion of the elastic member 100A is located between the first pressing member 30A and the connecting portion 90Ac. Furthermore, when assembling the connector 1A, the elastic member 100A is located within the fourth bolt insertion portion 90Ab.

[0048] By providing the elastic member 100A, before the head 2A and the plug harness 3A are engaged, the gate portion 90Aa and the first contact portion 20Aa of the head 2A are in the following positional relationship: (e.g., ...) Figure 8 As shown, the upper side of the first contact portion 20Aa ( Figure 8 The +z direction side) end becomes the position for entering the interior of the opening formed by the gate portion 90Aa. That is, the front end of the gate portion 90Aa is located above the front end of the first contact surface 20Ac ( Figure 8 The position is on the +z direction side. This structure ensures safety by preventing a person's fingers from directly contacting the first terminal 20A from the gate part 90Aa side. Even if a person presses the gate part 90Aa, the spring's reaction force due to the compression of the elastic member 100A makes it difficult to press more than a predetermined amount with the force of a finger. On the other hand, by using bolts 80A to fasten the head 2A and plug harness 3A to the nut 40A, the first terminal 20A is positioned upwards relative to the gate part 90A ( Figure 7 The gate component 90A moves from a position where the first contact surface 20Ac and the top end of the gate portion 90Aa are aligned (in the +z direction) to a position where the first contact surface 20Ac is aligned with the top end of the gate portion 90Aa. In other words, under the action of the elastic member 100A, the gate component 90A moves from a position where the end of the first contact portion 20Aa (first contact surface 20Ac) enters the opening formed by the gate component 90A until the completion of the fastening of the head 2A and the plug harness 3A using bolts 80A and nuts 40A. Figure 8 , Figure 9 The end of the first contact portion 20Aa is moved to a position where it is flush with the top end of the gate component 90A. Figure 7 In other words, before the fastening is completed, the gate component 90A is pressed by the elastic component 100A, thereby positioning the end of the gate portion 90Aa on the pressing direction side of the first pressing portion 30Aa, which is closer to the end of the first contact portion 20Aa (first contact surface 20Ac). Figure 8The position of the gate component 90A (in the +z direction). From before the fastening is completed to the completion, the gate component 90A moves to the position where the end of the first contact portion 20Aa (the first contact surface 20Ac) can communicate with the second contact portion 61Aa. Figure 8 (on the -z direction side). Thus, the first contact surface 20Ac engages with the second contact portion 61Aa. Furthermore, the gate component 90A has a recess 90Ae ( Figure 4 The gate component 90A can move downward relative to the first terminal 20A without interfering with the protrusion 10Aj. Figure 8 (Moves in the -z direction).

[0049] (Nut 40A)

[0050] Figure 11 This is a 3D diagram representing nut 40A. (Example) Figure 4 , Figure 11 As shown, nut 40A has a flange portion 40Aa and a nut portion 40Ab. Nut 40A is a flange nut or a nut having the function of a flange nut.

[0051] The flange portion 40Aa has a flange body portion 40Aa1 and a pair of locking arms 40Aa2. The flange body portion 40Aa1 is a thin, approximately octagonal metal plate with an upper surface 40Aa5 and a lower surface 40Aa6 opposite to the upper surface 40Aa5. In this example, the flange body portion 40Aa1 is sized to cover the connecting portion 30Ac. In the flange portion 40Aa, a hole portion 40Aa3 is provided in the center of the flange body portion 40Aa1, into which the second end portion 40Ab2 of the nut portion 40Ab is pressed. The flange portion 40Aa has a pair of locking arms 40Aa2 at the end of the flange body portion 40Aa1, and at the portion that contacts its front-rear position when assembling the connector 1A. Locking arms 40Aa2 connect to flange bodies 40Aa1 at two points away from a predetermined width and extend slightly outward in the horizontal direction (x-axis direction). From the front end of the extension destination, the extension direction changes upward (+z direction), and the arms extend further, joining at the extension destination in an opposing manner, thereby forming an opening 40Aa4. In other words, locking arms 40Aa2 each have an annular shape that connects to flange bodies 40Aa1 and has an opening 40Aa4. Nut 40A is assembled to the first housing 10A. Specifically, nut portion 40Ab is inserted into nut insertion portion 30Ab from below the first pressing member 30A. This insertion continues until the locking arms 40Aa2 engage with the protrusion 10Ak. Thus, nut 40A is assembled to the first housing 10A. When assembling the connector 1A, at least a portion of the lower surface 40Aa6 of the flange 40Aa, which is opposite to the surface (upper surface 40Aa5) of the pressing connector 30Ac, is exposed from the head 2A.

[0052] In this example, the nut portion 40Ab has a cylindrical shape, with one cylindrical end, namely the first end 40Ab1, and the other cylindrical end, namely the second end 40Ab2, which is opposite to the first end 40Ab1. The first end 40Ab1 is inserted into the nut insertion portion 30Ab from the side opposite to the side pressed by the first pressing portion 30Aa. The nut portion 40Ab is a so-called spacer nut or a nut that functions as a spacer nut. The nut portion 40Ab has a threaded portion. That is, the nut portion 40Ab has a threaded portion inside the cylindrical shape that can be fastened to the bolt 80A from the first end 40Ab1 toward the second end 40Ab2. In this example, the nut portion 40Ab integrates the flange portion 40Aa with the nut portion 40Ab by pressing the second end 40Ab2 into the hole portion 40Aa3.

[0053] <Plug Harness 3A>

[0054] Figure 12 This is a diagram showing the plug harness 3A. A is the top view, B is the DD section view of A, and C is the bottom view. Figure 13 This is a diagram showing the second shell 50A. A is a top view, B is a cross-sectional view of A (NN), C is a cross-sectional view of A (OO), and D is a cross-sectional view of A (MM).

[0055] like Figure 4 , Figure 12 As shown, the plug harness 3A includes a second housing 50A, a harness 60A, a second pressing member 70A, a sealing member 114A, a spherical washer 118A, a bolt 80A, and a sliding cover 55A. Figure 4 As shown, the plug harness 3A of this embodiment includes a sealing member 115A, a cable pressing member 116A, and a cover 117A around the harness 60A. It should be noted that in this embodiment, even without excluding the spherical washer 118A, bolt 80A, sliding cover 55A, sealing member 115A, cable pressing member 116A, and cover 117A, it is sometimes referred to as plug harness 3A.

[0056] (Second shell 50A)

[0057] like Figure 13 As shown, the second housing 50A has a generally rectangular shape with one end tapering, and is formed, for example, from an insulating material such as resin. The second housing 50A is used to position the second terminal 61A and the second pressing member 70A.

[0058] The second housing 50A has a pair of second holes 50Aa, an opening 50Ac, and a second bolt insertion portion 50Ab through which a bolt 80A can be inserted.

[0059] In this example, the pair of second holes 50Aa are on the back side ( Figure 13The -x direction side) is open and the front side ( Figure 13 The +x direction side) closing method is different from the length direction of the second housing 50A ( Figure 13 The second hole 50Aa is arranged parallel to (side by side) the x-axis direction. When the plug harness 3A is engaged with the head 2A, at least a portion of the second hole 50Aa is arranged parallel to the first contact surface 20Ac. For example... Figure 13 As shown in C, the second hole 50Aa has a hole shape where the front end side is slightly larger than the shape of the second terminal 61A, so that the second terminal 61A side of the wire harness 60A can be inserted. The central portion of the hole in the extending direction has a hole shape slightly larger than the outline of the cable 62A. The end near the entrance of the hole ( Figure 13 The -x direction side end) is formed into a rectangular hole shape so that the sealing component 115A (which is a waterproof component) is formed. Figure 4 It can be inserted.

[0060] The opening 50Ac includes a portion of each of the second hole portions 50Aa, intersecting a first axis (with) the direction of the hole of the second hole portion 50Aa. Figure 13 The z-axis is parallel to the axis in one direction ( Figure 13 It is formed by opening in the -z direction. Therefore, regarding the cross-sectional shape of the opening 50Ac, it includes a portion of the second hole 50Aa. Figure 13 The OO section of A has Figure 13 The shape shown in C, without the second hole 50Aa, for example Figure 13 The NN section of A has Figure 13 The shape shown in B. Therefore, as... Figures 5-7 As shown, the opening 50Ac is formed to house the base 10Ac, peripheral wall 10Af, gate cover 10Ae, and boss 10Ag of the first housing 10A within the second housing 50A. That is, the second housing 50A is formed to fit into the first housing 10A.

[0061] like Figure 13 As shown, the second bolt insertion portion 50Ab is inserted between a pair of second holes 50Aa and the aforementioned first shaft ( Figure 13 The second bolt insertion part 50Ab is arranged parallel to the z-axis and extends through the second housing 50A. The second bolt insertion part 50Ab is positioned opposite the first bolt insertion part 10Ab when the second housing 50A is engaged with the first housing 10A. The size of the hole in the second bolt insertion part 50Ab is a diameter d4 slightly larger than that of the bolt 80A near the surface 50Ad1 (described later). In the direction of entering the interior, it has a diameter d5 slightly larger than that of the protrusion 10Ag, and further into the interior, it expands towards the hole capable of receiving the base 10Ac.

[0062] On the upper surface 50Ae of the second housing 50A, from near the center of the second housing 50A to the front side ( Figure 13 The area (on the +x direction side) has a surface 50Ad1. In this example, the surface 50Ad1 is formed as a groove 50Ad that descends slightly from the upper surface 50Ae. The surface 50Ad1 has a defined area for mounting the second pressing member 70A. In this disclosure, the groove 50Ad is not a necessary structure; it is sufficient that the upper surface 50Ae has an area for mounting the second pressing member 70A (corresponding to the area of ​​the surface 50Ad1). Therefore, the upper surface 50Ae containing the surface 50Ad1 is sometimes simply referred to as the "upper surface 50Ae" or the "first surface". In addition, a plurality of protrusions 50Af are provided around the end periphery on the back side of the second housing 50A for fitting the cover 117A with the second housing 50A. Furthermore, a guide portion 50Ag is provided at the end in the width direction (y-axis direction) of the second housing 50A, protruding outward from the front surface side to the back side. The guide portion 50Ag engages with the engaging portion 55A2a of the sliding cover 55A (see reference). Figure 14 The sliding cover 55A engages with the sliding cover 55A, guiding its movement on the second housing 50A. A protrusion 55A6a (see reference 50Ae) is provided on the upper surface 50Ae for engaging with the sliding cover 55A. Figure 12 The engaging grooves are the first recess 50Ah and the second recess 50Ai. Both the first recess 50Ah and the second recess 50Ai are located at the center of the second housing 50A in the width direction (y-axis direction). The first recess 50Ah, along the end of the upper surface 50Ae on the back side, is, in this example, set to a width approximately twice the width of the protrusion 55A6a. The second recess 50Ai, connected to the back side of the groove 50Ad, is set to have a width slightly larger than the width of the protrusion 55A6a.

[0063] (Wire harness 60A)

[0064] like Figure 4 , Figure 12As shown, the wire harness 60A consists of a cable 62A and a second terminal 61A. The cable 62A includes a copper wire 62Aa made of a copper alloy and an insulating material 62Ab covering the copper wire 62Aa. One end of the cable 62A exposes the copper wire 62Aa. In this example, the exposed portion of the copper wire 62Aa has a gradient portion whose cross-section gradually changes from circular to rectangular, and a thin, generally cuboid portion (hereinafter also referred to as the "first cuboid portion") extending from this portion to the front end. The second terminal 61A is a thin copper plate having a generally cuboid portion (hereinafter also referred to as the "second cuboid portion"). In this example, the first cuboid portion and the second cuboid portion are fixed by ultrasonic welding. In this embodiment, the aforementioned gradient portion, first cuboid portion, and second cuboid portion are collectively referred to as the second terminal 61A. In particular, the second cuboid portion is also referred to as the second contact portion 61Aa. In this example, the second contact portion 61Aa is configured such that its width narrows further from the midpoint of the extending direction toward the front end. The second cuboid portion may also not be any other component, but rather formed of copper wire 62Aa. In this case, the second contact portion 61Aa is solidified by compression processing. That is, each pair of second terminals 61A is composed of multiple core wires (copper wires), and the second contact portion 61Aa is solidified by compression processing of these core wires to form a roughly cuboid shape. Compression processing facilitates the miniaturization of the plug harness 3A. Figure 7 As shown, the second contact portion 61Aa has a surface 61Aa1 and a surface 61Aa2 on the opposite side, thereby forming a plate thickness, i.e., a thickness h. In this example, the second contact portion 61Aa has a flat plate shape that allows insertion into the second hole portion 50Aa.

[0065] (Second pressing component 70A)

[0066] like Figure 4 As shown, the second pressing member 70A is a thin rectangular flat metal plate with rounded corners. When assembling the connector 1A including the sliding cover 55A, at least a portion of the second pressing member 70A is exposed from the plug harness 3A. In this example, the second pressing member 70A is made of stainless steel. The second pressing member 70A has a thin rectangular second pressing portion 70Aa, which is used to press a predetermined area (surface 50Ad1) of the outer surface of the second housing 50A, i.e., the upper surface 50Ae where the second bolt insertion portion 50Ab is provided, towards one direction (…). Figure 4The second pressing part 70Aa is pressed in the -z direction; the third bolt insertion part 70Ab allows the bolt 80A to be inserted into the center of the second pressing part 70Aa. In this example, the third bolt insertion part 70Ab is positioned opposite the second bolt insertion part 50Ab, separated by the sealing member 114A, when the second pressing member 70A is mounted on the surface 50Ad1. The second pressing member 70A and the designated area (surface 50Ad1) are in surface-to-surface contact. Therefore, even if the second housing 50A is, for example, formed of resin, it is possible to prevent the contact portion from sinking. In the connector 1A of this example, the bolt 80A is inserted into the second pressing member 70A via a spherical washer 118A.

[0067] Furthermore, in this example, the connector 1A includes a sealing member 114A forming an O-ring as a waterproof component. For example, when the busbars are threaded together, a waterproof housing is required for the waterproof structure. In the connector 1A, the sealing member 114A, as a waterproof component, is mounted from the upper surface 50Ae side to the second bolt insertion portion 50Ab, and on this basis, the second pressing portion 70Aa of the second pressing member 70A is mounted on the surface 50Ad1. That is, the sealing member 114A is provided on the second pressing member 70A side in the second bolt insertion portion 50Ab. Therefore, the connector 1A does not require a housing.

[0068] (Sliding cover 55A)

[0069] Figure 14 This is a 3D view representing the sliding cover 55A. Figure 15 yes Figure 3 An enlarged view of the sliding cover 55A and its surrounding area in the SS cross-sectional view of C. As described later, the sliding cover 55A is configured to move between a first position that does not cover the head of the bolt 80A and a second position that covers the head of the bolt 80A but does not cover a portion of the second pressing member 70A when the bolt 80A and nut 40A are tightened. Figure 7 As shown, the sliding cover 55A is a resin cover with a roughly U-shaped cross-section that covers the upper surface 50Ae of the second housing 50A. Figure 14 As shown, the sliding cover 55A has: a cover body 55A1 that covers the upper surface 50Ae of the second housing 50A; a sliding portion 55A2 that protrudes downward (in the -z direction) from both ends of the cover body 55A1 in the width direction (y-axis direction); and a bolt cover portion 55A5 that is located in the center of the cover body 55A1 and is formed to protrude upward (in the +z direction) from the cover body 55A1 to cover the bolt head of the bolt 80A.

[0070] like Figure 15As shown, the cover body 55A1 has a hole 55A4 on the back side (-x direction side) of the central portion in the width direction. This hole 55A4 is formed as a locking claw 55A6 with a fixed end on the back side and a free end on the front side (+x direction side). The locking claw 55A6 extends from the fixed end side toward the free end side, with the fixed end side extending with a constant width to the central portion, and the central portion gradually narrowing in width, while the free end side extends with a constant width. In order to engage with the first recess 50Ah and the second recess 50Ai provided on the upper surface 50Ae of the second housing 50A, the free end of the locking claw 55A6 has a protrusion 55A6a protruding downward (-z direction side). Figure 12 The cover body 55A1 has an opening 55A3 on the front surface side (+x direction side) of the central part so that the sliding cover 55A will not collide with the bolt 80A even if it moves from the first position to the second position.

[0071] The bolt cap 55A5 is based on a quadrangular prism shape with a generally trapezoidal cross-section extending from the back side to the front side. The bolt cap 55A5 has openings on both its front and lower surfaces, thus forming a hollow quadrangular prism shape with openings on both the front and lower surfaces. Figure 7 , Figure 15 As shown, a pair of rib-shaped guide portions 55A7a and 55A7b are provided inside the bolt cover portion 55A5. These guide portions 55A7a and 55A7b are separated from the front side to the back side by a width sufficient to contact the bolt head of the bolt 80A. In this disclosure, guide portions 55A7a and 55A7b are collectively referred to as "guide portion 55A7". Multiple grooves 55At are formed on the inner side of the guide portion 55A7b (bolt 80A side) along the vertical direction (z-axis direction). When the sliding cover 55A moves from the first position to the second position (described later), the grooves 55At contact the head of the bolt 80A, forming the direction for tightening the bolt 80A and the nut 40A, i.e., in... Figure 15 Rotating to the right from the perspective of [the angle of rotation] does not generate a force in the direction of loosening bolt 80A. Furthermore, the groove 55At at the second position can prevent loosening of bolt 80A even if it acts in the direction of loosening due to vibration or the like.

[0072] This makes the fastening of bolt 80A and nut 40A more reliable.

[0073] The sliding portions 55A2 protrude downwards (in the -z direction) from both ends of the cover body 55A1 in the width direction (y-axis direction). A engaging portion 55A2a protrudes slightly from the front ends of the protruding sides of the pair of sliding portions 55A2 in the direction (y-axis direction) towards the sliding portions 55A2 facing each other. The engaging portion 55A2a engages with the guide portion 50Ag of the second housing 50A, allowing the sliding cover 55A to move along the guide portion 50Ag.

[0074] <Connection method of connector 1A>

[0075] The connection method of connector 1A can be performed, for example, by assembling connector 1A through the following steps (1) to (11). However, the steps of the connection method of connector 1A are not limited to the following steps. It should be noted that the description of the installation steps of bolt 85A and collar 113A is omitted in the following description. It should be noted that in this disclosure, steps (1) to (10) are sometimes also referred to as the connection method of connector 1A.

[0076] (1) For waterproofing, such as Figure 9 As shown, a first sealing member 111A, which is an annular waterproof component, is installed from the bottom surface of the first housing 10A into a groove provided near the joint between the flange 10Ad and the base 10Ac. A second sealing member 112A, which is also an annular waterproof component, is installed from the protrusion 10Ag side of the first housing 10A into a groove provided around the base 10Ac.

[0077] (2) In order to mount one end of the elastic member 100A on the nut insertion part 30Ab of the first pressing member 30A, the other end of the elastic member 100A is inserted into the fourth bolt insertion part 90Ab of the gate member 90A.

[0078] (3) Insert the first pressing part 30Aa of the first pressing member 30A into the hole 20Ae of the first terminal 20A. In addition, insert the first contact part 20Aa of the first terminal 20A into the gate part 90Aa.

[0079] (4) In the state of (3), the gate part 90Aa is inserted into the first hole 10Aa, and the fourth bolt insertion part 90Ab is inserted into the boss 10Ag. The insertion depth is reached until the boss 10Aj and the boss 20Ad engage. By engaging the boss 10Aj and the boss 20Ad, a pair of first terminals 20A, the gate part 90A, the elastic member 100A, and the first pressing member 30A are held in the first housing 10A. It should be noted that at this time, through the insertion of the rib 90Ad into the hole 10Ai, the gate part 90A can move upward relative to the first housing 10A, and through the reaction force of the elastic member 100A, such as Figure 9 As shown, a pair of gate portions 90Aa are in a state where the periphery of one end of each of a pair of first contact portions 20Aa is exposed.

[0080] (5) Insert the nut portion 40Ab into the nut insertion portion 30Ab from below the first pressing member 30A. This insertion is performed until the locking arm portion 40Aa2 engages with the protrusion 10Ak (see reference). Figure 5The flange body 40Aa1 is a thin, approximately octagonal metal plate, roughly the size of the connecting portion 30Ac, covering it to some extent. The flange body 40Aa1 covers the connecting portion 30Ac with its lower surface 40Aa6 exposed. The nut portion 40Ab functions as a spacer nut, such as... Figure 9 As shown, it extends in the direction opposite to the insertion direction of bolt 80A (+z direction). The longer the spacer nut function of nut portion 40Ab is, the longer the fastening portion with bolt 80A can be ensured, thus the length of bolt 80A can be shortened accordingly. Therefore, when bolt 80A is inserted into second housing 50A, the tip of bolt 80A cannot reach the bottom of second housing 50A (the surface with opening 50Ac in the -z direction) (see reference). Figure 5 Therefore, by adopting the above-described structure for the nut 40A, the risk of damage to the first housing 10A caused by the contact between the bolt 80A and the first housing 10A, or the risk of the bolt 80A protruding further downward from the first housing 10A, can be reduced.

[0081] (6) With the sealing component 115A, cable pressing component 116A and cover 117A installed on the wire harness 60A, insert a pair of second terminals 61A into each of the second holes 50Aa (refer to...). Figure 6 Then, the sealing component 115A, the cable pressing component 116A, and the cover 117A are sequentially fitted into the first housing 10A.

[0082] (7) The first hole 10Aa is aligned with the opening 50Ac to fit the first housing 10A and the second housing 50A together. Figure 4 , Figure 6 ).

[0083] (8) As a waterproof component, in this example, the sealing component 114A forming an O-ring is mounted on the second bolt insertion part 50Ab from the upper surface 50Ae side, and the second pressing part 70Aa of the second pressing component 70A is mounted on the surface 50Ad1.

[0084] (9) With the back side (-x direction side) of the sliding cover 55A facing the front surface of the second housing 50A, engage the engaging portion 55A2a with the guide portion 50Ag of the second housing 50A, and install the sliding cover 55A onto the second housing 50A. Move the sliding cover 55A along the guide portion 50Ag to a position where the protrusion 55A6a of the sliding cover 55A engages with the first recess 50Ah (this position is also referred to as the "first position"). Thus, as long as no force greater than a specified amount is applied, the movement of the sliding cover 55A relative to the second housing 50A in the +x direction is restricted. The opening portion 55A3 is configured such that when the sliding cover 55A is in the first position, the positional relationship between the sliding cover 55A and the second housing 50A is such that it does not cover the top of the second bolt insertion portion 50Ab and allows the bolt 80A to be inserted from above. That is, the first position of the sliding cover 55A is a position in the connecting body 1A that does not cover the head of the bolt 80A.

[0085] (10) A spherical washer 118A is mounted above the third bolt insertion part 70Ab, opposite to the second pressing member 70A. Bolt 80A is inserted sequentially through the spherical washer 118A, the third bolt insertion part 70Ab, the sealing member 114A, the second bolt insertion part 50Ab, the first bolt insertion part 10Ab, the fourth bolt insertion part 90Ab, the elastic member 100A, the nut insertion part 30Ab, and the nut part 40Ab. Bolt 80A and nut 40A are then tightened to secure the head 2A and the plug harness 3A. The spherical washer 118A is used in the connector 1A. For example, even if one of the pair of first contact surfaces 20Ac is located lower than the other first contact surfaces 20Ac due to manufacturing errors, and they cannot be on the same surface in the assembly state, the offset can be absorbed, thereby ensuring that the pressing force on the pair of first contact surfaces 20Ac is equal to that on each other.

[0086] (11) After tightening the bolt 80A and the nut 40A, the sliding cover 55A is moved along the guide portion 50Ag to a position where the protrusion 55A6a engages with the second recess 50Ai (this position is also referred to as the "second position"). When the sliding cover 55A is in the second position, the positional relationship between the sliding cover 55A and the second housing 50A is as follows: The bolt cover portion 55A5 covers the head of the bolt 80A, and the guide portions 55A7a and 55A7b cover both sides of the head of the bolt 80A. This creates a structure in which tools such as wrenches for releasing the tightening of the bolt 80A and the nut 40A cannot be inserted. That is, the release of the tightening of the bolt 80A and the nut 40A is restricted. At this time, at least a portion of the second pressing member 70A protrudes from the plug harness 3A. That is, the second position is a position that covers the head of the bolt 80A but does not cover a portion of the second pressing member 70A. The connection method of the connector 1A is thus completed. It should be noted that when bolt 80A is not tightened to the specified amount, the bolt is detected to be not tightened to the specified amount by the interference between the bolt cap 55A5 and the head of bolt 80A.

[0087] Through the fastening of the plug harness 3A and the head 2A, the end of the first contact portion 20Aa enters the opening formed by the gate component 90A. Figure 8 , Figure 9 ) Move to a position where it is flush with the front end of the gate component 90A. Figure 7 In other words, under the action of the elastic member 100A, from the completion of the fastening of the head 2A and the plug harness 3A by the bolt 80A to the completion of the fastening, the gate member 90A moves from the position where the end of the first contact portion 20Aa (the first contact surface 20Ac) enters the opening formed by the gate member 90A. Figure 8 , Figure 9 The end of the first contact portion 20Aa is moved to a position where it is flush with the top end of the gate component 90A. Figure 7 In other words, before the fastening is completed, the gate component 90A is pressed by the elastic component 100A, thereby positioning the end of the gate portion 90Aa on the pressing direction side of the first pressing portion 30Aa, which is closer to the end of the first contact portion 20Aa (first contact surface 20Ac). Figure 8 The position of the gate component 90A (in the +z direction). From the time before fastening is completed until completion, the gate component 90A moves to the position where the end of the first contact portion 20Aa (the first contact surface 20Ac) can communicate with the second contact portion 61Aa. Figure 8 (on the -z direction side). Thus, the first contact surface 20Ac engages with the second contact portion 61Aa.

[0088] The connector 1A is configured such that the nut insertion portion 30Ab of the nut insertion portion 40Ab is opposite to the fourth bolt insertion portion 90Ab, the fourth bolt insertion portion 90Ab is opposite to the first bolt insertion portion 10Ab, the first bolt insertion portion 10Ab is opposite to the second bolt insertion portion 50Ab, and the second bolt insertion portion 50Ab is opposite to the third bolt insertion portion 70Ab via the sealing member 114A. That is, the relative positional relationship of the third bolt insertion portion 70Ab, the second bolt insertion portion 50Ab, the first bolt insertion portion 10Ab, the fourth bolt insertion portion 90Ab, and the nut portion 40Ab is such that the bolt 80A and the nut 40A can be fastened together. The connector 1A of this disclosure enables communication between each first contact portion 20Aa and each second contact portion 61Aa through the fastening based on the bolt 80A.

[0089] The relative positional relationship of the nut portion 40Ab, the first bolt insertion portion 10Ab, the second bolt insertion portion 50Ab, and the third bolt insertion portion 70Ab is as follows: Each first terminal 20A is inserted into each first hole 10Aa from the first contact surface 20Ac (this state is also referred to as the "first state"). In this first state, a pair of first pressing portions 30Aa are capable of pressing the first terminal 20A respectively. A pair of second terminals 61A are inserted into a pair of second holes 50Aa respectively. The first holes 10Aa are aligned with the openings 50Ac to fit the first housing 10A and the second housing 50A. The second pressing portion 70Aa of the second pressing member 70A is mounted on a designated area (surface 50Ad1). The first pressing portions 30Aa of the first pressing member 30A are able to abut against the surface of the first terminal 20A opposite to the first contact surface 20Ac (this state up to this point is also referred to as the "second state"). In the second state, the relative positions of the nut part 40Ab, the first bolt insertion part 10Ab, the second bolt insertion part 50Ab, and the third bolt insertion part 70Ab are such that a bolt (bolt 80A) is inserted and the bolt 80A and the nut 40A can be fastened. Through the fastening of the bolt 80A and the nut 40A, the first contact part 20Aa and the second contact part 61Aa are respectively connected.

[0090] In this embodiment, the connector 1A is configured such that the head 2A fits into the plug harness 3A, and this fitting and fastening can be achieved using a single bolt 80A and nut 40A. The connector 1A is configured to directly engage the first terminal 20A and the second terminal 61A. This direct engagement can be achieved using a single bolt 80A and nut 40A. Therefore, it eliminates the need for additional accessories, such as the second terminal accessory body 86 in Patent Document 1, which engages with the terminals for inter-terminal engagement. Furthermore, the connector 1A is configured such that the first terminal 20A and the second terminal 61A can directly engage and conduct electricity. In Patent Document 1, a structure using a spring 88 as an elastic member for engagement is employed. Spring-based engagement requires plating to reduce contact resistance. The connector 1A achieves inter-terminal conduction through the direct engagement of the first terminal 20A and the second terminal 61A, resulting in high contact force generated by the bolt tightening force, thus significantly reducing resistance and eliminating the need for plating. Therefore, the connector 1A of this disclosure can suppress the increase in the number of parts and can achieve a connection that can withstand large currents.

[0091] In this embodiment, the upper side of the surface 61Aa1 and the first contact portion 20Aa ( Figure 7 The wire harness 60A is mounted by abutting against the end (first contact surface 20Ac) of the +z direction side. This embodiment is not limited thereto.

[0092] For example, it can also be configured such that the wire harness 60A is in the length direction of the wire harness 60A ( Figure 7 Rotate 90 degrees with respect to the x-axis direction, so that surface 61Aa3 or surface 61Aa4 (refer to...) Figure 7 The first terminal 20A abuts against the upper end (first contact surface 20Ac) of the first contact portion 20Aa. Alternatively, it can be configured such that the first terminal 20A extends along the length of the wire harness 60A ( Figure 4 Rotate 90 degrees around the x-axis (refer to the x-axis direction) so that surface 61Aa1 (refer to the x-axis direction) is rotated 90 degrees. Figure 7 It abuts against the flat surface 20Aa1 (or surface 20Aa2) of the first contact portion 20Aa. In these cases, the shapes of other components, including the first housing 10A, the second housing 50A, etc., are appropriately changed according to the configuration of the shapes.

[0093] Therefore, in this embodiment, as long as the first contact portion 20Aa and the second contact portion 61Aa can be directly engaged, the pair of first contact portions 20Aa and the pair of second contact portions 61Aa can be configured such that at least one of them is erected "along" the insertion direction of the bolt 80A, or at least one of them is erected "relative to" the insertion direction of the bolt 80A.

[0094] In the connector 1A of this disclosure, at least a portion of the metal second pressing member 70A is exposed from the plug harness 3A during assembly of the connector 1A. Therefore, even when the connector 1A of this disclosure generates heat due to current, it is able to release heat from the second pressing member 70A, which has a higher thermal conductivity than the material of the second housing 50A.

[0095] In the connector 1A of this disclosure, during assembly, at least a portion of the lower surface 40Aa6 of the metal flange 40Aa, opposite to the surface (upper surface 40Aa5) of the pressing connection portion 30Ac, is exposed from the head 2A. Therefore, even when the connector 1A generates heat due to current, heat can be released from the flange 40Aa, which has a higher thermal conductivity than the material of the first housing 10A. Furthermore, the flange body 40Aa1 is a thin, approximately octagonal metal plate, its size covering the connection portion 30Ac. Therefore, when a component or product using the connector 1A has a cooling function, the heat generated by the connector 1A can be directed to that cooling function. For example, the flange body 40Aa1 of the flange 40Aa can be connected to a part of another component or product. Thus, by effectively utilizing the cooling function of other components or products, the connector 1A can be actively cooled.

[0096] The embodiments of this disclosure have been described above. In this disclosure, copper is cited as an example of a conductive component, stainless steel as a metal, and resin, glass epoxy resin, etc., as examples of insulation. However, the connector of this disclosure is not limited to the specific materials used in the examples; other materials may be used as long as they fall within the scope of the conductive components, metal components, insulating components, etc., described in this disclosure. Furthermore, the connector described above can, of course, be appropriately modified without departing from the spirit of this disclosure.
