Summary of the Invention

Problems to be Solved by the Invention

[0004] The connector assembly of Patent Document 1 secures the first connector 12 and the second connector 14 to each other by inserting a fastening bolt 190 when the first connector 12 and the second connector 14 are mated together (paragraph 0074). Furthermore, in this connector assembly, electrical conductivity between the first connector 12 and the second connector 14 is achieved by electrically conductive contact between each first terminal fitting 16 and each second terminal fitting 18 (paragraph 0073). Here, the second terminal fitting 18 is composed of a second terminal fitting body 86 and a clip spring 88 as an elastic member attached to the tip (front end) of the second terminal fitting body 86 (paragraph 0040). In other words, the connector assembly of Patent Document 1 employs a configuration in which the connectors are mated by inserting a fastening bolt 190 and electrical conductivity is achieved by the clip spring 88. For example, as a connection structure for high currents, there are problems such as an increase in the number of parts and insufficient contact strength.

[0009] <<First Embodiment>> Hereinafter, the connector according to the first embodiment of this disclosure will be described with reference to the drawings. Components having the same function will be given the same number, and redundant explanations will be omitted. Figure 1 is a diagram showing one embodiment of the connector according to the first embodiment, where A is a perspective view, B is a plan view, and C is a left side view. Figure 2 is an exploded perspective view of the connector 1A. Figure 3 is a cross-sectional view of KK in Figure 1B. Figure 4 is a cross-sectional view of LL in Figure 1B. Figure 5 is a cross-sectional view of II in Figure 1C.

[0010] The connectors disclosed herein are, for example, connectors for high currents of several hundred amperes. However, the connectors disclosed herein are not limited in terms of the magnitude of the current and do not prevent application with even larger or smaller currents. In this embodiment, the connector 1A consists of a header 2A and a plug harness 3A that mates with the header 2A, as shown in Figures 1 and 2.

[0011] <Header 2A> FIG. 6 is a view showing header 2A, where A is a perspective view, B is a plan view, and C is a left side view. FIG. 7 is a cross-sectional view taken along line F-F of FIG. 6C. As shown in FIGS. 2 and 6, header 2A includes a first housing 10A, a pair of first terminals 20A, a first pressing member 30A, a shutter member 90A, an elastic member 100A, a first sealing member 111A, a second sealing member 112A, and a nut 40A. The header 2A of this embodiment includes four sets of bolts 85A and collars 113A for joining to other components or products (not shown) such as a substrate. However, as a configuration of header 2A, bolts 85A and collars 113A may not be provided.

[0012] (First housing 10A) FIG. 8 is a view showing the first housing 10A, where A is a plan view, B is a cross-sectional view taken along line Q-Q of A, C is a cross-sectional view taken along line R-R of A, and D is a cross-sectional view taken along line P-P of A.

[0013] As shown in FIG. 7, the first housing 10A houses the first terminals 20A, the first pressing member 30A, the shutter member 90A, the elastic member 100A, and the nut 40A, and positions at least a part of each of them. When the first pressing member 30A is inserted into the first housing 10A, as shown in FIG. 5, the convex portion 20Ad and the convex portion 10Aj are fitted together. Thereby, the pair of first terminals 20A, the shutter member 90A, the elastic member 100A, and the first pressing member 30A are held within the first housing 10A. The first housing 10A is formed of an insulating material such as resin. In this example, as shown in FIG. 8, it has a base 10Ac based on a substantially octagonal rectangular cross-section, and a flange portion 10Ad that extends in an outer direction expanding the cross-sectional area of the octagonal rectangle from the lower end side of the base 10Ac (the end side in the -z direction in FIG. 8) to form an outer shape of a rounded quadrangle.

[0014] The base 10Ac has a peripheral wall 10Af formed such that a part of an edge on the back side (-x direction side in FIG. 8) of its upper surface 10Ac1 is in an open state and the other edges are surrounded and stand up. The base 10Ac has a pair of first hole portions 10Aa in a rectangular hole shape that penetrate vertically (in the Z-axis direction of FIG. 8) and are provided in parallel within the region surrounded by the peripheral wall 10Af, and between the pair of first hole portions 10Aa, there is a first bolt insertion portion 10Ab provided in parallel to the pair of first hole portions 10Aa through which the bolt 80A can be inserted. On the upper surface 10Ac1, shutter covers 10Ae are provided around the edges of each first hole portion 10Aa so as to stand up upward (+z direction in FIG. 8) from the first hole portion 10Aa. The shutter cover 10Ae has a shape that covers the periphery of the tip side of the first contact portion 20Aa (FIG. 7). On the upper surface 10Ac1, a boss 10Ag is formed along the upward (+z direction in FIG. 8) from the end periphery of the first bolt insertion portion 10Ab. The hole size of the first bolt insertion portion 10Ab including the hole size of the boss 10Ag has a diameter d1 slightly larger than the diameter of the bolt 80A at the entrance of the hole of the boss 10Ag. In the direction of entering inside (-z direction in FIG. 8), it has a diameter d2 slightly larger than the diameter of the elastic member 100A, and when entering further inside, it has a hole shape of a rectangular cross-section with a width W (FIG. 8D) and a length L (FIG. 8B) and is connected to the first hole portion 10Aa. A pair of convex portions 10Ak with which the lock arm portion 40Aa2 of the nut 40A engages are formed outside the hole shape. The upper surface 10Ac1 is provided with a pair of hole portions 10Ai through which the rib 90Ad of the shutter member 90A can be inserted between each shutter cover 10Ae and the boss 10Ag.

[0015] As shown in FIG. 8A, the flange portion 10Ad is provided with hole portions 10Ah near the four rounded corners into which the collar 113A (FIG. 2) can be inserted by caulking. The collar 113A is formed of a metal such as stainless steel, and bolts 85A can be inserted into each of the hole portions 10Ah in which the collar 113A is mounted (FIG. 6).

[0016] (First terminal 20A) As shown in Figures 2 and 4, the first terminal 20A is a conductive flat plate having a first contact portion 20Aa and an extended portion 20Ab connected to the first contact portion 20Aa. In this example, the first terminal 20A is made of copper.

[0017] The first contact portion 20Aa is a flat plate that, from the viewpoint of Figure 4, forms an octagonal shape with the corners of a vertically elongated, approximately rectangular shape missing, and has a first contact surface 20Ac at its upper end (towards the second contact portion 61Aa, the +z direction side in Figure 4). The first contact portion 20Aa has a flat plate shape that allows insertion into each of the first holes 10Aa (Figure 8) from the first contact surface 20Ac side. Here, the first contact portion 20Aa is divided into approximately three equal regions from top to bottom in the viewpoint of Figure 4: the upper section, the middle section, and the lower section, with the region corresponding to the middle section being referred to as the connecting portion 20Ai. The upper and lower sections of the first contact portion 20Aa are provided to extend along the z-axis direction shown in Figure 2 (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 connecting section 20Ai is configured to connect the upper and lower sections such that the lower section is shifted outward relative to the upper section.

[0018] Each of the first contact portions 20Aa has a roughly elongated rectangular hole 20Ae in the center of the connecting portion 20Ai into which the first pressing portion 30Aa of the first retaining member 30A is inserted. The ends of the hole 20Ae in the longitudinal direction are cut out so that the shape of the hole expands toward the first contact surface 20Ac side. When the first pressing portion 30Aa is inserted into the hole 20Ae, the first contact portion 20Aa takes an upright position relative to the first retaining member 30A. Each of the first contact portions 20Aa is provided with a protrusion 20Ad (Figure 2) slightly above the center of the surface that comes into contact with the outside when the connecting body 1A is assembled (towards the second contact portion 61Aa, the +z direction side in Figure 4). The protrusion 20Ad has a roughly trapezoidal cross-sectional shape, which gradually changes in thickness as it extends downward (in the -z direction in Figure 2), such that the thickness of the first terminal 20A in the portion where the protrusion 20Ad is provided increases. In this example, the protrusion 20Ad is formed by dowel processing, and a recess is formed on the surface opposite to the surface on which the protrusion 20Ad is formed, at a position opposite to the protrusion 20Ad. Because the first terminal 20A has the protrusion 20Ad, the first terminal 20A engages with the protrusion 10Aj (Figure 8D) provided in the first hole 10Aa of the first housing 10A, and is held in the first housing 10A (see Figure 5).

[0019] The extension portion 20Ab extends downward from the lower end of the first contact portion 20Aa (the end on the -z direction side in Figure 4) while maintaining the width of the lower end (away from the second contact portion 61Aa, in the -z direction in Figure 4). In this example, the extension portion 20Ab has a hole portion 20Ag slightly above its center (towards the first contact portion 20Aa, on the +z direction side in Figure 4) that can be used for connection with other parts or products (not shown).

[0020] (First retaining member 30A) The first pressing member 30A is a plate made of an insulating material having the shape of a thin rectangular parallelepiped. In this example, the first pressing member 30A is made of glass epoxy resin. However, it may also be made of a separator structure of glass epoxy resin and stainless steel, for example, as long as insulation is ensured. As shown in Figure 2, the first pressing member 30A has a pair of first pressing portions 30Aa, which are regions at both ends in the longitudinal direction (y-axis direction in Figure 2), and a connecting portion 30Ac that connects the pair of first pressing portions 30Aa. The connecting portion 30Ac is provided with a nut insertion portion 30Ab in its center, through which the nut portion 40Ab of the nut 40A can be inserted. In the first state, where each of the first terminals 20A is inserted into each of the first holes 10Aa (Figure 8) from the first contact surface 20Ac, the first retaining member 30A presses each of the first terminals 20A from the side opposite to the first contact surface 20Ac (side 20Ae1 in Figure 4) toward the first contact surface 20Ac. When the header 2A is assembled, the nut insertion portion 30Ab into which the nut portion 40Ab is inserted is configured to face the fourth bolt insertion portion 90Ab.

[0021] In addition, the first retaining member 30A may be used by any other method as long as it can press the first terminal 20A from the side opposite to the first contact surface 20Ac toward the first contact surface 20Ac. In this case, the shapes of other parts will be adjusted as appropriate, such as so that the nut 40A can continue to press the first retaining member 30A.

[0022] (Shutter component 90A) As shown in Figure 2, the shutter member 90A is an insulating member having a pair of shutter sections 90Aa, a connecting section 90Ac connecting the pair of shutter sections 90Aa, and a fourth bolt insertion section 90Ab, which is boss-shaped and located in the center of the connecting section 90Ac, through which a bolt 80A can be inserted. In this example, the shutter member 90A is made of resin.

[0023] The shutter section 90Aa has a hollow, box-like shape with an opening in the vertical direction (z-axis direction in Figure 2) that allows the insertion and movement of the first terminal 20A. The shutter section 90Aa has a shape that covers the area around the tip side of the first contact section 20Aa. In other words, the pair of shutter sections 90Aa cover the area around one end of each of the pair of first contact sections 20Aa, leaving that end exposed.

[0024] As shown in Figure 7, the shutter member 90A is provided with a pair of ribs 90Ad on the connecting portion 90Ac in order to more firmly support the shutter portion 90Aa and the fourth bolt insertion portion 90Ab.

[0025] The shape of the hole inside the fourth bolt insertion portion 90Ab is such that the entrance has a diameter slightly larger than that of the bolt 80A, and the inner diameter is formed to be a hole shape with a diameter d3 that is slightly larger than that of the elastic member 100A, so that the elastic member 100A can be inserted.

[0026] (Elastic member 100A) As shown in Figure 7, the elastic member 100A of this embodiment has the shape of a coil spring. In this example, the elastic member 100A is made of stainless steel. The inner diameter of the elastic member 100A is slightly larger than that of the bolt 80A so that the bolt 80A can be inserted through it. One end of the elastic member 100A is mounted on the nut insertion portion 30Ab of the first retaining member 30A. The other end is inserted into the fourth bolt insertion portion 90Ab. As a result, when the header 2A is assembled, at least a portion of the elastic member 100A is located between the first retaining member 30A and the connecting portion 90Ac. Also, when the connector 1A is assembled, the elastic member 100A is located inside the fourth bolt insertion portion 90Ab.

[0027] By providing the elastic member 100A, the shutter portion 90Aa and the first contact portion 20Aa in the header 2A are in the following positional relationship before the header 2A and the plug harness 3A are fitted together. As shown in Figure 6, the upper end (the +z direction in Figure 6) of the first contact portion 20Aa is positioned inside the opening formed by the shutter portion 90Aa. That is, the tip of the shutter portion 90Aa is located above (the +z direction in Figure 6) the tip of the first contact surface 20Ac. This structure ensures safety by preventing a person's finger or other object from directly touching the first terminal 20A from the shutter portion 90Aa side. Even if a person were to press down on the shutter portion 90Aa, the elastic member 100A would compress, acting as a spring reaction force, making it difficult to press down beyond a predetermined amount with the force of a finger. On the other hand, by fastening the header 2A and the plug harness 3A with a bolt 80A and a nut 40A, the first terminal 20A moves upward relative to the shutter member 90A (in the +z direction in Figure 5) until the first contact surface 20Ac is flush with the tip of the shutter portion 90Aa. In other words, the elastic member 100A causes the shutter member 90A to move from a position where the end of the first contact portion 20Aa (first contact surface 20Ac) is inserted into the opening formed by the shutter member 90A (Figures 6, 7) to a position where the end of the first contact portion 20Aa and the tip of the shutter member 90A are flush (Figure 5), from before the fastening of the header 2A and the plug harness 3A with the bolt 80A and the nut 40A is completed until it is completed. To put it another way, before the fastening is complete, the shutter member 90A is pressed against the elastic member 100A, so that the end of the shutter portion 90Aa is located on the side of the pressing direction of the first pressing portion 30Aa (the +z direction in Figure 6) from the end of the first contact portion 20Aa (the first contact surface 20Ac). From before the fastening is complete until it is complete, the shutter member 90A moves to a position where the end of the first contact portion 20Aa (the first contact surface 20Ac) can communicate with the second contact portion 61Aa (the -z direction in Figure 6). As a result, the first contact surface 20Ac joins with the second contact portion 61Aa.Furthermore, because the shutter member 90A has a recess 90Ae (Figure 2), the shutter member 90A can move downward (towards the -z direction in Figure 6) relative to the first terminal 20A without interfering with the protrusion 10Aj.

[0028] (Nut 40A) Figure 9 is a perspective view showing nut 40A. As shown in Figures 2 and 9, nut 40A has a flange portion 40Aa and a nut portion 40Ab. Nut 40A is a flange nut, or a nut that functions as a flange nut.

[0029] The flange portion 40Aa has a flange body portion 40Aa1 and a pair of locking arm portions 40Aa2. The flange body portion 40Aa1 is a roughly octagonal, thin metal plate having an upper surface 40Aa5 and a lower surface 40Aa6 which is the surface opposite to the upper surface 40Aa5. In this example, the flange body portion 40Aa1 is large enough to cover the connecting portion 30Ac. The flange portion 40Aa is provided with a hole 40Aa3 in the center of the flange body portion 40Aa1 into which the second end portion 40Ab2 of the nut portion 40Ab can be press-fitted. The flange portion 40Aa has a pair of locking arm portions 40Aa2 at the end of the flange body portion 40Aa1, in the portion that corresponds to the front-rear position when the connecting body 1A is assembled. Each of the locking arms 40Aa2 connects to the flange body 40Aa1 from two positions separated by a predetermined width, extending slightly outward in the horizontal direction (x-axis direction). From the tip of the extended portion, the direction of extension changes upward (+z direction), and it extends further, connecting so that the two portions face each other at the extended portion, thereby forming an opening 40Aa4. In other words, each of the locking arms 40Aa2 has an annular shape that connects to the flange body 40Aa1 and has an opening 40Aa4. The nut 40A is incorporated into the first housing 10A. Specifically, the nut portion 40Ab is inserted into the nut insertion portion 30Ab from below the first retaining member 30A. This insertion is continued until the locking arm 40Aa2 engages with the protrusion 10Ak. This incorporates the nut 40A into the first housing 10A. When the connector 1A is assembled, at least a portion of the lower surface 40Aa6 of the flange portion 40Aa, which is opposite to the surface (upper surface 40Aa5) that presses against the connecting portion 30Ac, is exposed from the header 2A.

[0030] In this example, the nut portion 40Ab has a cylindrical shape and includes a first end portion 40Ab1, which is one end of the cylindrical shape, and a second end portion 40Ab2, which is the other end of the cylindrical shape and the end opposite to the first end portion 40Ab1. The first end portion 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, inside the cylindrical shape, the nut portion 40Ab has a threaded portion that can be fastened with the threaded portion of the bolt 80A, extending from the first end portion 40Ab1 to the second end portion 40Ab2. In this example, the flange portion 40Aa and the nut portion 40Ab are integrated by press-fitting the second end portion 40Ab2 into the hole portion 40Aa3.

[0031] <Plug Harness 3A> Figure 10 shows the plug harness 3A, where A is a plan view, B is a cross-sectional view of A at DD, and C is a bottom view. Figure 11 shows the second housing 50A, where A is a plan view, B is a cross-sectional view of A at NN, C is a cross-sectional view of A at OO, and D is a cross-sectional view of A at MM.

[0032] As shown in Figures 2 and 10, the plug harness 3A includes a second housing 50A, a harness 60A, a second retaining member 70A, a sealing member 114A, a spherical washer 118A, a bolt 80A, and a slide cover 55A. In this embodiment, as shown in Figure 2, the plug harness 3A includes a sealing member 115A, a cable retainer 116A, and a cover 117A around the harness 60A. In this embodiment, the plug harness 3A may still be referred to as such even if the spherical washer 118A, bolt 80A, slide cover 55A, sealing member 115A, cable retainer 116A, and cover 117A are not included.

[0033] (Second Housing 50A) As shown in Figure 11, the second housing 50A has a roughly rectangular parallelepiped shape with one end tapering, and is made of an insulating material such as resin. The second housing 50A positions the second terminal 61A and the second retaining member 70A.

[0034] 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.

[0035] In this example, the pair of second holes 50Aa are arranged parallel to the longitudinal direction (x-axis direction in Figure 11) of the second housing 50A, with the back side (-x direction side in Figure 11) being open and the front side (+x direction side in Figure 11) being closed. The second holes 50Aa are arranged parallel to the first contact surface 20Ac, at least a portion of which faces the first contact surface 20Ac when the plug harness 3A is fitted with the header 2A. As shown in Figure 11C, the second holes 50Aa have a shape where the tip of the hole is slightly larger than the shape of the second terminal 61A, so that the second terminal 61A side of the harness 60A can be inserted. The central part in the extension direction of the hole has a shape where it is slightly larger than the outer shape of the cable 62A. The end near the entrance of the hole (the -x direction side end in Figure 11) is formed as a rectangular hole so that a sealing member 115A (Figure 2), which is a waterproof member, can be inserted.

[0036] The opening 50Ac encompasses a portion of each of the second holes 50Aa and is formed to open in one direction (the -z direction in Figure 11) along the first axis (the axis parallel to the z-axis in Figure 11) that intersects with the direction of the holes in the second holes 50Aa. Therefore, the cross-sectional shape of the opening 50Ac is such that the OO cross-section in Figure 11A, which encompasses a portion of the second holes 50Aa, has the shape shown in Figure 11C, while the portion without the second holes 50Aa, for example, the NN cross-section in Figure 11A, has the shape shown in Figure 11B. As a result, the opening 50Ac forms an opening that allows the base 10Ac, peripheral wall 10Af, shutter cover 10Ae, and boss 10Ag of the first housing 10A to fit inside the second housing 50A, as shown in Figures 3 to 5. In other words, the second housing 50A is formed to be able to fit into the first housing 10A.

[0037] As shown in Figure 11, the second bolt insertion portion 50Ab is provided between a pair of second holes 50Aa so as to penetrate the second housing 50A parallel to the first axis (z-axis in Figure 11) described above. The second bolt insertion portion 50Ab is provided in a position opposite to the first bolt insertion portion 10Ab when the second housing 50A is fitted with the first housing 10A. The size of the hole in the second bolt insertion portion 50Ab has a diameter d4 that is slightly larger than the bolt 80A near the surface 50Ad1 described later. In the direction of going inward, it has a diameter d5 that is slightly larger than the boss 10Ag, and further inward it expands to a hole that can accommodate the base 10Ac.

[0038] The upper surface 50Ae of the second housing 50A has a surface 50Ad1 in the region extending from near the center of the second housing 50A to the front side (the +x direction in Figure 11). In this example, surface 50Ad1 is formed as the surface of a groove 50Ad that is slightly lower than the upper surface 50Ae. Surface 50Ad1 forms a predetermined region on which the second retaining member 70A is mounted. In this disclosure, the groove 50Ad is not an essential structure; it is sufficient to have a region on the upper surface 50Ae on which the second retaining member 70A is mounted (the region corresponding to surface 50Ad1). Therefore, the upper surface 50Ae including surface 50Ad1 may be simply referred to as "upper surface 50Ae" or "first surface". In addition, a number of protrusions 50Af are provided around the rear end 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 of the second housing 50A in the width direction (y-axis direction), projecting outward from the front side to the rear side. The guide portion 50Ag engages with the engaging portion 55A2a (see Figure 12) of the slide cover 55A to guide the movement of the slide cover 55A on the second housing 50A. The upper surface 50Ae is provided with a first recess 50Ah and a second recess 50Ai, which are grooves for engaging with the convex portion 55A6a (see Figure 10) of the slide cover 55A. Both the first recess 50Ah and the second recess 50Ai are located in the center of the second housing 50A in the width direction (y-axis direction). The first recess 50Ah is provided along the rear end of the upper surface 50Ae, and in this example, has a width approximately twice that of the convex portion 55A6a. The second recess 50Ai is provided so as to be connected to the back side of the groove 50Ad, and has a width slightly larger than the width of the protrusion 55A6a.

[0039] (Harness 60A) As shown in Figures 2 and 10, harness 60A consists of cable 62A and second terminal 61A. Cable 62A consists of copper wire 62Aa made of a copper alloy and insulating material 62Ab covering the copper wire 62Aa. One end of cable 62A has the copper wire 62Aa exposed. In this example, the exposed portion of copper wire 62Aa has a gradually changing section where the cross-section gradually changes from circular to rectangular, and a thin, roughly rectangular section (hereinafter also referred to as the "first rectangular section") extending from that section to the tip. The second terminal 61A has a thin copper plate in the roughly rectangular section (hereinafter also referred to as the "second rectangular section"). In this example, the first rectangular section and the second rectangular section are fixed together by ultrasonic welding. In this embodiment, the gradually changing section, the first rectangular section, and the second rectangular section are collectively referred to as the second terminal 61A. In particular, the second rectangular parallelepiped portion will also be referred to as the second contact portion 61Aa. In this example, the second contact portion 61Aa is configured such that its width narrows in a step from the middle of the extension direction towards the tip. The second rectangular parallelepiped portion can also be formed from copper wire 62Aa instead of a separate component. In this case, the second contact portion 61Aa is solidified by compaction processing. That is, each of the pair of second terminals 61A is composed of multiple core wires (copper wires), and each of the second contact portions 61Aa is formed into a roughly rectangular parallelepiped by solidifying its core wires by compaction processing. Compaction processing promotes miniaturization of the plug harness 3A. As shown in Figure 5, the second contact portion 61Aa has a surface 61Aa1 and a surface 61Aa2 on the opposite side, which together constitute the plate thickness h. In this example, the second contact portion 61Aa has a flat plate shape that can be inserted into the second hole portion 50Aa.

[0040] (Second retaining member 70A) As shown in Figure 2, the second retaining member 70A is a thin, rectangular metal plate with rounded corners. When the connector 1A, including the slide cover 55A, is assembled, at least a portion of the second retaining member 70A is exposed from the plug harness 3A. In this example, the second retaining member 70A is made of stainless steel. The second retaining member 70A has a thin, rectangular second pressing portion 70Aa for pressing a predetermined area (surface 50Ad1) of the upper surface 50Ae, which is the outer surface of the second housing 50A and is provided with the second bolt insertion portion 50Ab, in one direction (the -z direction in Figure 2), and a third bolt insertion portion 70Ab in the center of the second pressing portion 70Aa through which the bolt 80A can be inserted. The third bolt insertion portion 70Ab is provided in this example at a position opposite to the second bolt insertion portion 50Ab via the sealing member 114A when the second retaining member 70A is mounted on the surface 50Ad1. The second retaining member 70A and the predetermined area (surface 50Ad1) are in surface-to-surface contact. Therefore, even if the second housing 50A is made of resin, for example, indentation (indentation) of the contact portion is prevented. In the connector 1A of this example, the bolt 80A is inserted into the second retaining member 70A via the spherical washer 118A.

[0041] In this example, the connector 1A is equipped with a sealing member 114A that forms an O-ring as a waterproofing member. For example, when busbars are screwed together, a separate waterproof over-housing is required for a waterproof structure. In the connector 1A, the sealing member 114A, which acts as a waterproofing member, is attached to the second bolt insertion portion 50Ab from the upper surface 50Ae side, and then the second pressing portion 70Aa of the second retaining member 70A is mounted on the surface 50Ad1. That is, the sealing member 114A is provided on the second retaining member 70A side of the second bolt insertion portion 50Ab. Therefore, the connector 1A does not require an over-housing.

[0042] (Slide cover 55A) Figure 12 is a perspective view showing the slide cover 55A. Figure 13 is an enlarged view of the slide cover 55A and its surroundings in the SS cross-sectional view of Figure 1C. As will be described later, the slide cover 55A is configured to be movable between a first position in which it does not cover the head of the bolt 80A and a second position in which it covers the head of the bolt 80A but does not cover a part of the second retaining member 70A when the bolt 80A and nut 40A are fastened together. As shown in Figure 5, the slide cover 55A is a resin cover with a roughly U-shaped cross-section that covers the upper surface 50Ae of the second housing 50A. As shown in Figure 12, the slide cover 55A includes a cover body 55A1 that covers the upper surface 50Ae of the second housing 50A, slide portions 55A2 that protrude downward (-z direction) from both ends of the cover body 55A1 in the width direction (y-axis direction), and a bolt cover portion 55A5 provided in the center of the cover body 55A1 and formed to protrude upward (+z direction) from the cover body 55A1 and cover the bolt head of the bolt 80A.

[0043] As shown in Figure 13, the cover body 55A1 is provided with a hole 55A4 formed on the rear side (-x direction side) of the center in the width direction, which has a locking claw portion 55A6 where the rear side is a fixed end and the front side (+x direction side) is a free end. The locking claw portion 55A6 extends from the fixed end side to the free end side with a constant width on the fixed end side to the center, then gradually changes in width so that it narrows in the center, and extends with a constant width on the free end side. The free end of the locking claw portion 55A6 is provided with a protrusion 55A6a (Figure 10) that projects downward (-z direction side) 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 cover body 55A1 is provided with an opening 55A3 on the front side (+x direction side) of the center so that the slide cover 55A does not collide with the bolt 80A even when it moves from the first position to the second position.

[0044] The bolt cover portion 55A5 is based on the shape of a rectangular prism with a roughly trapezoidal cross-section extending from the back to the front. The bolt cover portion 55A5 has openings on the front and bottom sides, thus forming a hollow rectangular prism shape with openings on the front and bottom sides. Inside the bolt cover portion 55A5, as shown in Figures 5 and 13, a pair of rib-shaped guide portions 55A7a and 55A7b are provided, spaced apart from the front to the back by a width that allows contact with the bolt head of the bolt 80A. In this disclosure, the guide portions 55A7a and 55A7b are collectively referred to as "guide portion 55A7". The guide portion 55A7b has a plurality of grooves 55At formed on its inner side (bolt 80A side) in the vertical direction (z-axis direction). When the slide cover 55A moves from the first position to the second position, as described later, the groove 55At comes into contact with the head of the bolt 80A and rotates clockwise from the viewpoint shown in Figure 13, which is the direction in which the bolt 80A and nut 40A are fastened, and no force is generated in the direction of loosening the bolt 80A. Furthermore, even if vibrations or other factors cause the fastening of the bolt 80A to loosen, the groove 55At in the second position can prevent this loosening. This makes the fastening between the 80A bolt and the 40A nut more reliable.

[0045] The sliding portion 55A2 protrudes downward (-z direction) from both ends of the cover body 55A1 in the width direction (y-axis direction). The protruding ends of the pair of sliding portions 55A2 have engaging portions 55A2a that protrude slightly toward the other sliding portion 55A2 (y-axis direction). The engaging portions 55A2a engage with the guide portion 50Ag of the second housing 50A, enabling the slide cover 55A to move along the guide portion 50Ag.

[0046] <Connection method for connector 1A> The connection of connector 1A can be carried out, for example, by assembling connector 1A through the following steps (1) to (11). However, the steps for connecting connector 1A are not limited to those described below. Note that the explanation of the steps for attaching bolt 85A and collar 113A is omitted in the following description. In this disclosure, steps (1) to (10) may also be referred to as the method for connecting connector 1A.

[0047] (1) For waterproofing, as shown in Figure 7, the first sealing member 111A, which is an annular waterproofing member, is attached to a groove provided near the joint between the flange portion 10Ad and the base 10Ac from the bottom side of the first housing 10A. The second sealing member 112A, which is an annular waterproofing member, is attached to a groove provided around the base 10Ac from the boss 10Ag side of the first housing 10A.

[0048] (2) In order to mount one end of the elastic member 100A on the nut insertion portion 30Ab of the first retaining member 30A, the other end of the elastic member 100A is inserted into the fourth bolt insertion portion 90Ab of the shutter member 90A.

[0049] (3) Insert each of the first pressing portions 30Aa of the first retaining member 30A into the respective holes 20Ae of the first terminal 20A. Also, insert the first contact portion 20Aa of the first terminal 20A into the shutter portion 90Aa.

[0050] (4)(3) In the state of (3), the shutter portion 90Aa is inserted into the first hole portion 10Aa, and the fourth bolt insertion portion 90Ab is inserted into the boss 10Ag. The insertion depth is continued until the protrusion 10Aj and the protrusion 20Ad engage. When the protrusion 10Aj and the protrusion 20Ad engage, the pair of first terminals 20A, the shutter member 90A, the elastic member 100A, and the first retaining member 30A are held inside the first housing 10A. At this time, as the rib 90Ad passes through the hole portion 10Ai, the shutter member 90A is able to move upward relative to the first housing 10A, and due to the reaction force of the elastic member 100A, the pair of shutter portions 90Aa cover the area around one end of each of the pair of first contact portions 20Aa, with that end exposed, as shown in Figure 7. (5) Insert the nut portion 40Ab into the nut insertion portion 30Ab from below the first retaining member 30A. Insertion is carried out until the lock arm portion 40Aa2 engages with the protrusion 10Ak (see Figure 3). The flange body portion 40Aa1 is a thin, approximately octagonal metal plate large enough to cover the connecting portion 30Ac. The flange body portion 40Aa1 covers the connecting portion 30Ac with its lower surface 40Aa6 exposed. The nut portion 40Ab has the function of a spacer nut and extends in the direction opposite to the insertion direction of the bolt 80A (+z direction), as shown in Figure 7. The longer the spacer nut function of the nut portion 40Ab, the longer the fastening portion with the bolt 80A can be secured, and therefore the length of the bolt 80A can be shortened. Therefore, when the bolt 80A is inserted into the second housing 50A, it is possible to configure the bolt so that its tip does not reach the bottom surface of the second housing 50A (the surface on the -z side where the opening 50Ac is provided) (see Figure 3). Thus, by adopting the above configuration, the nut 40A can reduce the risk of damage to the first housing 10A due to the bolt 80A coming into contact with the first housing 10A, or the risk of the bolt 80A protruding further downward from the first housing 10A.

[0051] (6) With the sealing member 115A, cable retainer 116A, and cover 117A attached to the harness 60A, insert each of the pair of second terminals 61A into the respective second holes 50Aa (see Figure 4). Then, fit the sealing member 115A, cable retainer 116A, and cover 117A into the first housing 10A in this order.

[0052] (7) The first housing 10A and the second housing 50A are fitted together with the first hole 10Aa and the opening 50Ac facing each other (Figures 2 and 4).

[0053] (8) As a waterproofing member, in this example, a sealing member 114A that forms an O-ring is attached to the second bolt insertion portion 50Ab from the upper surface 50Ae side, and the second pressing portion 70Aa of the second retaining member 70A is mounted on the surface 50Ad1.

[0054] (9) The slide cover 55A is mounted on the second housing 50A by facing the front side (-x direction side) of the slide cover 55A toward the front side of the second housing 50A and engaging the engaging portion 55A2a with the guide portion 50Ag of the second housing 50A. The slide cover 55A is moved along the guide portion 50Ag to a position where the convex portion 55A6a of the slide cover 55A engages with the first recess 50Ah (this position is also called the "first position"). As a result, the slide cover 55A is restricted from moving in the +x direction relative to the second housing 50A unless a force greater than a predetermined amount is applied. When the slide cover 55A is in the first position, the opening 55A3 is configured such that the positional relationship between the slide cover 55A and the second housing 50A does not cover the upper part of the second bolt insertion portion 50Ab, and the bolt 80A can be inserted from above. In other words, the first position in the slide cover 55A is the position in the connector 1A that does not cover the head portion of the bolt 80A.

[0055] (10) A spherical washer 118A is mounted above the third bolt insertion portion 70Ab so as to face the second retaining member 70A. The bolt 80A is inserted in the following order: spherical washer 118A, third bolt insertion portion 70Ab, sealing member 114A, second bolt insertion portion 50Ab, first bolt insertion portion 10Ab, fourth bolt insertion portion 90Ab, elastic member 100A, nut insertion portion 30Ab, and nut portion 40Ab. The header 2A and the plug harness 3A are fastened by tightening the bolt 80A and nut 40A. The connector 1A uses a spherical washer 118A, and even if, for example, one of the pair of first contact surfaces 20Ac is positioned lower than the other first contact surface 20Ac due to manufacturing errors, or if they cannot be positioned on the same plane during assembly, the misalignment can be absorbed, and the pressing force on the pair of first contact surfaces 20Ac can be made equal and equivalent. (11) After fastening the bolt 80A and nut 40A, the slide cover 55A is moved along the guide portion 50Ag to a position where the convex portion 55A6a engages with the second recess 50Ai (this position is also called the "second position"). When the slide cover 55A is in the second position, the positional relationship between the bolt cover portion 55A5 and the second housing 50A is as follows: The bolt cover portion 55A5 covers the top of the head of the bolt 80A, and the guide portions 55A7a and 55A7b cover both sides of the head of the bolt 80A. This configuration prevents the insertion of a tool to release the fastening of the bolt 80A and nut 40A, such as a spanner wrench. In other words, it restricts the release of the fastening of the bolt 80A and nut 40A. At this time, at least a part of the second retaining member 70A is exposed from the plug harness 3A. In other words, the second position is a position that covers the head of the bolt 80A but does not cover a part of the second retaining member 70A. This completes the connection method for the connector 1A. If the bolt is not tightened to the specified amount, the bolt cover portion 55A5 will interfere with the head of the bolt 80A, thereby detecting that the bolt is not tightened to the specified amount.

[0056] As described above, the fastening of the plug harness 3A and the header 2A causes the end of the first contact portion 20Aa to move from a position where it is inside the opening formed by the shutter member 90A (Figures 6 and 7) to a position where it is flush with the tip end of the shutter member 90A (Figure 5). In other words, the elastic member 100A causes the shutter member 90A to move from a position where the end of the first contact portion 20Aa (first contact surface 20Ac) is inside the opening formed by the shutter member 90A (Figures 6 and 7) to a position where the end of the first contact portion 20Aa and the tip end of the shutter member 90A are flush (Figure 5), before and after the fastening of the header 2A and the plug harness 3A by the bolt 80A is completed. To put it another way, before the fastening is complete, the shutter member 90A is pressed against the elastic member 100A, so that the end of the shutter portion 90Aa is located on the side of the pressing direction of the first pressing portion 30Aa (the +z direction in Figure 6) from the end of the first contact portion 20Aa (the first contact surface 20Ac). From before the fastening is complete until it is complete, the shutter member 90A moves to a position where the end of the first contact portion 20Aa (the first contact surface 20Ac) can communicate with the second contact portion 61Aa (the -z direction in Figure 6). As a result, the first contact surface 20Ac joins with the second contact portion 61Aa.

[0057] The connector 1A is configured such that the nut insertion portion 30Ab into which the nut portion 40Ab is inserted faces the fourth bolt insertion portion 90Ab, the fourth bolt insertion portion 90Ab faces the first bolt insertion portion 10Ab, the first bolt insertion portion 10Ab faces the second bolt insertion portion 50Ab, and the second bolt insertion portion 50Ab is positioned to face the third bolt insertion portion 70Ab via the sealing member 114A. In other words, the relative positional relationship between 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 a bolt 80A can be inserted and the bolt 80A and nut 40A can be fastened together. The connector 1A of this disclosure is electrically connected to each of the first contact portions 20Aa and each of the second contact portions 61Aa by fastening with the bolt 80A.

[0058] The relative positional relationship between the nut portion 40Ab, the first bolt insertion portion 10Ab, the second bolt insertion portion 50Ab, and the third bolt insertion portion 70Ab can be described as follows: The first terminals 20A are inserted into each of the first holes 10Aa from the first contact surface 20Ac (this state is also called the "first state"). In this first state, the pair of first pressing portions 30Aa are made capable of pressing each of the first terminals 20A. The pair of second terminals 61A are inserted into the pair of second holes 50Aa. The first housing 10A and the second housing 50A are fitted together with the first holes 10Aa and the openings 50Ac facing each other. The second pressing portion 70Aa of the second retaining member 70A is mounted on a predetermined area (surface 50Ad1). Each of the first pressing portions 30Aa of the first retaining member 30A can be made to contact the surface of the first terminal 20A opposite to the first contact surface 20Ac (this state is also called the "second state"). In the second state, the relative positional relationship between the nut portion 40Ab, the first bolt insertion portion 10Ab, the second bolt insertion portion 50Ab, and the third bolt insertion portion 70Ab is such that a bolt (bolt 80A) can be inserted and the bolt 80A and nut 40A can be fastened together. The fastening of the bolt 80A and nut 40A is such that electrical conductivity is established between each of the first contact portions 20Aa and each of the second contact portions 61Aa.

[0059] The connector 1A of this embodiment is configured to fit the header 2A and the plug harness 3A together, and the fitting is fastened using a single bolt 80A and nut 40A. The connector 1A is configured to directly join the first terminal 20A and the second terminal 61A. This direct joining is configured to be performed using a single bolt 80A and nut 40A. Therefore, a separate fitting that connects to the terminals to join them together is not required, such as the second terminal fitting body 86 in Patent Document 1. Furthermore, the connector 1A is configured so that the first terminal 20A and the second terminal 61A can be directly joined and electrically connected. Patent Document 1 employs a structure that uses a clip spring 88 as an elastic member for joining. Joining with a spring requires plating to reduce contact resistance. The connector 1A achieves conductivity between terminals through direct connection between the first terminal 20A and the second terminal 61A, and since a high contact force is obtained due to the bolt fastening force, electrical resistance can be significantly reduced, thus eliminating the need for plating. Therefore, the connector 1A of this disclosure can suppress an increase in the number of parts and realize a connection that can withstand high currents.

[0060] In this embodiment, the harness 60A is mounted so that its surface 61Aa1 abuts against the upper end (first contact surface 20Ac) of the first contact portion 20Aa (the +z direction side in Figure 5). This embodiment is not limited to this.

[0061] For example, the harness 60A may be rotated 90 degrees around its longitudinal direction (the x-axis direction in Figure 5) and configured to bring surface 61Aa3 or surface 61Aa4 (see Figure 5) into contact with the upper end (first contact surface 20Ac) of the first contact portion 20Aa. Alternatively, the first terminal 20A may be rotated 90 degrees around its longitudinal direction (the x-axis direction in Figure 2) and configured to bring surface 61Aa1 (see Figure 5) into contact with 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 and the second housing 50A, will be modified as appropriate to match the arrangement of the shapes.

[0062] Therefore, in this embodiment, the connector 1A may be provided such that, insofar as the first contact portion 20Aa and the second contact portion 61Aa can be directly joined, at least one of the pair of first contact portions 20Aa and the pair of second contact portions 61Aa is positioned to stand upright "alongside" the direction in which the bolt 80A is inserted, or at least one of the pair of first contact portions 20Aa and the pair of second contact portions 61Aa is positioned to stand upright "relative to" the direction in which the bolt 80A is inserted.

[0063] In the connector 1A of this disclosure, when the connector 1A is assembled, at least a portion of the second retaining member 70A made of metal is exposed from the plug harness 3A. Therefore, even if the connector 1A of this disclosure generates heat due to the current, heat can be released from the second retaining member 70A, which has a higher thermal conductivity than the material of the second housing 50A.

[0064] In the connector 1A of this disclosure, when the connector 1A is assembled, at least a portion of the lower surface 40Aa6 of the metal flange portion 40Aa, opposite to the surface (upper surface 40Aa5) that presses against the connecting portion 30Ac, is exposed from the header 2A. Therefore, even if the connector 1A of this disclosure generates heat due to electric current, heat can be released from the flange portion 40Aa, which has a higher thermal conductivity than the material of the first housing 10A. Furthermore, the flange body portion 40Aa1 is a thin, approximately octagonal metal plate large enough to cover the connecting portion 30Ac. Therefore, if the 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 portion 40Aa1 of the flange portion 40Aa can be connected to a part of another component or product. This allows the connector 1A to be actively cooled by utilizing the cooling function of the other component or product.

[0065] The embodiments of this disclosure have been described above. In this disclosure, copper is given as an example of a conductive member, stainless steel as a metal, and resins such as glass epoxy resin as insulating materials.
