Description

Technical Field

[0001] The present invention relates to a cable connector, which is a type of cable connector in which cable terminals are provided from the side opposite to the connection side of the other connector. Background Technology

[0002] Patent Document 1 discloses an example of a cable connector having the above-described structure. The split-shielded connector of Patent Document 1 is configured to include a plug housing 100 and a base housing 200, and a cable terminal is provided in a base insert 400 disposed in the base housing 200.

[0003] The base insert 400 is typically used when mounted to the outer surface of a housing or similar object. Therefore, the installation of cable terminals relative to the base insert 400 is performed on the side opposite to the connection side of the plug housing 100 and the base housing 200, i.e., inside the housing. Furthermore, these cable terminals must be positioned in a specified orientation, or in other words, at a specified angle in the circumferential direction of the cable terminals within a specified location on the base insert 400. The cable terminals are installed by inserting them into terminal insertion holes in the base insert 400, which is located in the base housing 200. Since the circumferential surface of these cable terminals is circular, their installation direction is not particularly restricted.

[0006] Patent Document 1: Chinese Patent No. 111478125 Summary of the Invention

[0007] The technical problem that the invention aims to solve

[0008] Generally, cable terminal installation is performed with the cable attached to the cable terminal. Therefore, in order to position the cable terminal at a specified orientation—that is, at a specified angle circumferentially—the user sometimes needs to rotate the cable terminal along with the cable circumferentially within the confined working space inside the housing. For example, this can become very cumbersome when the cable is thick and rotation is difficult.

[0009] In addition, the circumference of the cable terminal is circular and its orientation is not particularly restricted. Therefore, space needs to be provided around the entire circumference of the terminal insertion hole used to house the cable terminal for locking the cable terminal, which is not suitable for miniaturization.

[0010] The purpose of this invention is to provide a cable connector that eliminates the above-mentioned disadvantages.

[0011] Technical solutions adopted to solve technical problems

[0012] To address the aforementioned technical problems, one embodiment of the present invention provides a cable connector with the following features: the cable connector includes: a connecting member; a connecting module disposed on the connecting member; and a cable terminal disposed on the connecting module, the cable terminal including: a cable fixing member fixed to a cable; a contact member disposed on the side opposite to the cable fixing member in the length direction of the cable terminal; and an intermediate member disposed between the contact member and the cable fixing member, wherein the cable terminal is inserted into the connecting module in the following manner: from the side opposite to the connecting side of the other connector toward the connecting side, in the order of the contact member, the intermediate member, and the cable fixing member. The through hole has a locking portion on the outer peripheral surface of the intermediate member, and correspondingly, a pair of corresponding locking portions are provided on the inner peripheral surface of the through hole. The pair of corresponding locking portions and the adjacent pair of corresponding locking portions are arranged face to face in the opposite direction of the pair of corresponding locking portions. The locking portions are provided in a state where they protrude outward away from the outer peripheral surface of the intermediate member and can be elastically displaced. When the cable terminal is inserted into the through hole and the intermediate member reaches a predetermined position of the through hole, the end of the locking portion engages with any one of the pair of corresponding locking portions, thereby preventing the cable terminal from coming out of the through hole from the connection side of the housing and the connecting member toward the side opposite to the connection side.

[0013] According to this method, the engaging portion for engaging the cable terminal is positioned opposite to the inner circumferential surface of the through hole. Furthermore, corresponding engaging portions for engaging these engaging portions are also positioned opposite each other. Therefore, the installation operation can be performed by rotating the cable terminal approximately 90 degrees at most. In addition, the cable terminal is positioned in a predetermined direction, eliminating the need for a large space for locking the terminal, making it suitable for miniaturization.

[0014] Invention Effects

[0015] According to the present invention, a cable connector is provided that allows for easy installation of cable terminals. Furthermore, a cable connector suitable for miniaturization is also provided. Attached Figure Description

[0048] Hereinafter, a preferred embodiment for carrying out the invention will be described in detail with reference to the accompanying drawings. In the following description, terms indicating specific directions or positions (e.g., terms including "front," "rear," "left," "right," "side," "end," "top," and "bottom") are used as needed, but these terms are used to facilitate understanding of the invention with reference to the accompanying drawings, and not to limit the technical scope of the invention through the meaning of these terms. Furthermore, the accompanying drawings are schematic diagrams, and the scale of each dimension may not necessarily correspond to the actual scale.

[0049] exist Figure 1 as well as Figure 2 The image shows a perspective view of a cable connector assembly, and more specifically, a perspective view of a cable connector assembly according to an embodiment of the present invention, with cables connected, and more specifically, a cable connector assembly including a receptacle connector. The cable connector assembly 100 includes a plug connector (parallel connector) 1 in addition to the receptacle connector 6. Figure 1 and Figure 2 The states before and after connecting them are shown respectively. Additionally, Figure 3 The image shows a bottom view of the plug connector 1. Figure 3 As shown, the bottom surface of the plug connector 1 has a partial opening, through which the plug connector 1 connects to the socket connector 6 on the bottom surface side (Z2 side).

[0050] One end of cable 2 (2A, 2B) is connected to plug connector 1, and one end of cable 7 is connected to receptacle connector 6. Two cables 2A and 2B are connected to plug connector 1, and six cables 7 are connected to receptacle connector 6, but the number of connections is not limited to this. Furthermore, when multiple identical or similar components exist and it is considered convenient to distinguish between them, the letters "A" and "B" are added to the reference numerals (the same applies below). Plug connector 1 can move freely even after the cables are connected, while receptacle connector 6 is used to be fixed to a housing or wall surface (not shown). Once fixed, receptacle connector 6 is only exposed to the outside on the connection side (Z1 side), while the side opposite to the connection side (Z2 side) is usually housed inside the housing or similar component.

[0051] remove Figures 1 to 3 In addition, refer to Figure 4 as well as Figure 5 . Figure 4 and Figure 5The figures show a perspective view of the plug connector after the cover has been removed and an exploded perspective view of the plug connector. The plug connector 1 mainly includes: a housing (shell) 10; a locking operating lever 20 mounted in a manner that allows free rotation relative to the housing 10; a cover 50 that closes the open top surface side (Z1 side) of the housing 10; and multiple terminals 80 disposed on the housing 10. Figure 4 , Figure 5 ), 86 ( Figure 3 ), 87 ( Figure 3 , Figure 5 (First terminal); a resin first connection module 35 for mounting terminals 80 and 86 on the housing 10, and a second connection module 36 for mounting terminal 87 on the housing 10; a first shielding member 41 and a second shielding member 42 for electrically shielding a portion of cables 2A and 2B from the outside; and a first fixing member 31 and a second fixing member 32 for fixing cables 2A and 2B to the housing 10.

[0052] The outer casing 10 can be formed of a conductive material or by electroplating a resin material with metal. The outer casing 10 has storage spaces 101 to 104. Figure 5 In the storage spaces 101 to 104, in addition to one end of cables 2A and 2B, and for example, the internal shielding components 3a and 3b after the outer sheath of the cables have been stripped, various component parts 35, 36, 41, 42, etc., are also stored. The bottom side (Z2 side) of the storage spaces 101 to 104 is opened through the aforementioned opening 110, and the top side (Z1 side) is open. In the illustrated example, the top side (Z1 side) corresponds to the connection side (Z1 side) in the connection direction "Z" between the plug connector 1 and the socket connector 6, and the bottom side (Z2 side) corresponds to the side (Z2 side) opposite to the connection side (Z1 side) in the connection direction "Z", but it is not necessarily limited to this arrangement. For example, the side can be the connection side instead of the top side, or the top side and bottom side can be reversed.

[0053] Storage spaces 101 to 104 are formed by a plurality of walls 11 to 14 extending between the top surface (Z1) and the bottom surface (Z2). These walls 11 to 14 include: a first wall (front wall) 11 and a second wall (rear wall) 12 arranged opposite each other in a length direction (X) orthogonal to the connecting direction (Z); a third wall (left wall) 13A and a fourth wall (right wall) 13B arranged opposite each other in a width direction (Y) orthogonal to both the connecting direction (Z) and the length direction (X); and a fifth wall (left connecting wall) 14A and a sixth wall (right connecting wall) 14B connecting the first wall 11 to the third and fourth walls 13A and 13B, respectively. The first to fourth walls 11, 12, 13A, and 13B are generally rectangular flat plates, while the fifth wall 14A and the sixth wall 14B are formed with a curvature of approximately 90 degrees within a plane (XY plane) intersecting the connecting direction (Z).

[0054] The space surrounded by the first to sixth walls 11 to 14 is divided by a plate-shaped conductive partition 17 extending along the width direction "Y" between the first wall 11 and the second wall 12, and a plate-shaped conductive shielding plate 16 extending along the length direction "X" between the third wall 13A and the fourth wall 13B. As a result, four storage spaces 101 to 104 are formed. The first to sixth walls 11 to 14 are interconnected in the plane (XY plane) intersecting the connection direction (Z) to form a generally rectangular frame, and each forms the outer contour of the plug connector 1.

[0055] The third wall 13A and the fourth wall 13B are each provided with a protruding member 15 that extends outward in the width direction "Y" from the third wall 13A and the fourth wall 13B, respectively. A top surface 152a is formed on the top 152 of the protruding member 15, which extends in a plane ("XY plane") that is approximately orthogonal to the connection direction "Z", and a cover 50 can be provided thereon. In order to maintain strength, the protruding member 15 extends across the top surface side (Z1 side) and the bottom surface side (Z2 side) while the top 152 and the bottom 150 are connected by a continuous member 151.

[0056] The top 11a of the top surface side (Z1 side) of the first wall 11 is positioned further towards the bottom surface side (Z2 side) in the longitudinal direction "X" than the tops 13a and 13b of the top surface sides (Z1 side) of the third wall 13A and the fourth wall 13B located on the first wall 11 side (X1 side). In addition, the tops 13a and 13b of the top surface sides (Z1 side) of the third wall 13A and the fourth wall 13B located on the first wall 11 side (X1 side), and the tops 14a and 14b of the top surface sides (Z1 side) of the fifth wall 14A and the sixth wall 14B located on the first wall 11 side (X1 side) in the longitudinal direction "X" are configured to move closer to the bottom surface side (Z2 side) as they move from the second wall 12 side towards the first wall 11 side. In other words, the height of the wall on the first wall 11 side (X1 side) of the outer casing 10 is set to decrease as it moves towards the bottom surface side (Z2 side). In addition, in the example shown, the tops 13a and 13b of the top surface side (Z1 side) of the third wall 13A and the fourth wall 13B are curved towards the first wall 11, but it does not necessarily have to be curved. For example, it can be stepped or straight.

[0057] exist Figures 6 to 8 The image shows a side view of the receptacle connector with the operating lever 20 in a changed angular position relative to the housing 10. Figure 6 The angle position shown (bottom side) and Figure 8 Rotate approximately 90 degrees between the indicated angle positions (top side).

[0058] The operating lever 20 has a bilaterally symmetrical shape in the width direction "Y" and is approximately C-shaped in the plane (XY plane) intersecting the connection direction (Z). The operating lever 20 includes: a base 21 extending in the width direction "Y"; a pair of arms 23A, 23B arranged opposite each other in the width direction "Y"; and a pair of curved connecting portions 24A, 24B connecting each end of the base 21 in the width direction "Y" to one end of each of the pair of arms 23A, 23B, thereby being configured to surround the outer side of the first wall 11, the third wall 13A, and the fourth wall 13B of the housing 10. The base 21 is a flat plate having a length in the width direction "Y" that is approximately rectangular, and a tab 212 for improving the operability of the operating lever 20 is provided on its top surface side (Z1 side). A pair of curved connecting parts 24A and 24B are bent at approximately 90 degrees in the plane (XY plane) intersecting the connection direction (Z), similar to the fifth wall 14A and the sixth wall 14B forming the outer casing 10, so as not to hinder the rotation of the operating lever 20, and their degree of bending is the same as that of the fifth wall 14A and the sixth wall 14B.

[0059] The operating lever 20 is mounted on the third wall 13A and fourth wall 13B of the housing 10 at the arm portions 23A and 23B. To mount the arm portions 23A and 23B to the third wall 13A and fourth wall 13B, mounting portions are provided on the outer surfaces of the third wall 13A and fourth wall 13B, and corresponding mounting portions are provided on the inner surfaces of the arm portions 23A and 23B. The mounting portions are particularly located on the outer surfaces of the third wall 13A and fourth wall 13B on the side of the first wall 11 (X1 side) in the longitudinal direction "X". In other words, they are located on the outer surfaces of the third wall 13A and fourth wall 13B, whose height decreases towards the bottom surface (Z2 side) in the connection direction "Z". By positioning the mounting portions in this manner, the forces received through the arm portions 23A and 23B can be borne on the bottom surface (Z2 side) of the housing 10, providing a more robust mounting structure. Furthermore, the third wall 13A and the fourth wall 13B are connected to the first wall 11 via the fifth wall 14A and the sixth wall 14B, thus enabling them to withstand sufficient forces through the arms 23A and 23B.

[0060] The mounting part and its corresponding mounting part only need to be able to mount the operating lever 20 to the housing 10 in a manner that allows it to rotate freely relative to the housing 10. As shown in the example, the mounting part can be a cylinder 132 extending outward in the width direction "Y", and the corresponding mounting part can be a circular through hole 232. During installation, the operating lever 20 is axially supported on the housing 10 by inserting the cylinder 132 into the through hole 232.

[0061] Although not clearly shown in the accompanying drawings, the corresponding mounting portion (232) is mounted on the mounting portion (132) with the spacing in the width direction "Y" of the corresponding mounting portion widened. More specifically, the circular through hole 232 is embedded into the cylinder 131 by utilizing the elastic restoring force generated by the widening in the width direction "Y". The elastic restoring force is generated in any part or multiple parts of the base 21, the arms 23A, 23B, or the pair of curved connecting portions 24A, 24B that connect the base 21 to the arms 23A, 23B.

[0062] In order to be in Figure 6 The position of the operating lever 20 relative to the housing 10 is stable at the indicated angle. In other words, a locking mechanism is provided to stabilize the position of the operating lever 20 relative to the housing 10 when the operating lever 20 is in a locked state or in an unused state. An outwardly protruding portion 111 (locking portion) is provided on the bottom outer wall of the first wall 11 of the housing 10, and correspondingly, an inwardly protruding portion 211 (corresponding locking portion) is provided on the bottom inner wall of the base 21 of the operating lever 20. When the operating lever 20 is rotated to reach... Figure 6When the angle position is shown, the inner protrusion 211 of the operating lever 20 is engaged with the outer protrusion 111 of the housing 10, and as a result, the angular position of the operating lever 20 relative to the housing 10 is stably maintained.

[0063] Similarly, in order to be in Figure 7 or Figure 8 The operating lever 20 at the indicated angle position is stable relative to the housing 10, and a locking mechanism is provided. Protrusions 232a (locking portions) extending radially from the outer edge of the through hole 232 are respectively provided on the inner surfaces of the arms 23A and 23B. Correspondingly, grooves 132a (corresponding locking portions) extending radially from the outer edge of the cylinder 132 are respectively provided on the outer surfaces of the third wall 13A and the fourth wall 13B. When the operating lever 20 is rotated to reach... Figure 7 or Figure 8 When the angle position is shown, the protrusions 232a of the arms 23A and 23B are inserted into the grooves 132a of the third wall 13A and the fourth wall 13B, and as a result, the angular position of the operating lever 20 relative to the housing 10 is stably maintained.

[0064] The operating lever 20 cooperates with the receptacle connector 6 to form a locking mechanism. With the housing 10 connected to the receptacle connector 6 at a predetermined point, the operating lever 20 is then... Figure 8 The angle position shown (top side) is towards Figure 6 Rotate the lever to the indicated angle position (bottom side) until the operating lever 20 reaches... Figure 6 At the indicated angle position (bottom side), the housing 10 is locked to the socket connector 6, thus maintaining the connection between the plug connector 1 and the socket connector 6. As a locking mechanism, locking portions (230) are provided on the arms 23A and 23B, and correspondingly, a locking portion (630) is provided on the socket connector 6. In the illustrated example, as the locking portion (230), a protrusion 230 protruding outward in the width direction "Y" is provided on the outer wall of each of the arms 23A and 23B.

[0065] Like the outer casing 10, the cover 50 can be made of a conductive material or a resin material plated with metal. The cover 50 is installed on the outer casing 10, enclosing the open storage spaces 101 to 104. When the cover 50 is installed on the outer casing 10, the bottom surface of the cover 50 is positioned on the tops 11a, 12a, 13a, 13b, 14a, 14b, etc. of the first to sixth walls 11 to 14 (see reference). Figure 5 The top surface (Z1 side) of the outer casing 10 is sealed, preferably by inserting a pad (not shown). By providing the cover 50, the dustproof, waterproof and shielding properties of the storage spaces 101 to 104 can be improved.

[0066] The cover 50 includes: a main body 51 having a top surface 51a extending in a plane ("XY plane") substantially orthogonal to the connection direction "Z"; a first expansion 52 positioned in the length direction "X" closer to the end side of the cable 2 than the main body 51; and second expansions 53 and 54 positioned in the width direction "Y" further outward than the main body 51.

[0067] The first expansion portion 52 has a top 11a extending from the top surface 51a toward the top of the first wall 11 (see reference). Figure 5 ( ) The extended surface. In the illustrated example, the first expansion 52 is a curved surface.

[0068] The second expansion portions 53 and 54 have tops 13a and 13b extending from the top surface 51a toward the third wall 13A and the fourth wall 13B (see reference). Figure 5 (Extended surfaces.) In the illustrated example, the second expansions 53 and 54 are curved surfaces, just like the first expansion 52.

[0069] By providing the first expansion portion 52 and the second expansion portions 53 and 54, the cover 50 has a predetermined height in the connection direction "Z". As a result, it forms a hollow three-dimensional shape with internal space. Therefore, when installed on the outer casing 10 and closing the open storage spaces 101 to 104, it can be easily and accurately positioned relative to the outer casing 10 while avoiding collision with the stored components stored in the storage spaces 101 to 104. As a result, the dustproof, waterproof, and shielding properties of the storage spaces 101 to 104 can be further improved.

[0070] A protrusion 55 is provided on the top surface 51a of the main body 51, extending outward in the width direction "Y" from the third wall 13A and the fourth wall 13B. The protrusion 55 is positioned between the second expansion portion 53 and the second expansion portion 54 in the length direction "X". The cover 50 is provided at the protrusion 55 on the top surface 152a of the protruding members 15 respectively provided on the third wall 13A and the fourth wall 13B of the outer casing 10, and is fixed to the outer casing 10 by means of threaded holes 550 provided on the cover 50, threaded holes 152b provided on the protruding members 15, and screws 500.

[0071] A portion of the protrusion 55, more specifically, the end of the protrusion 55 located at the outermost point in the width direction "Y", is formed as a plate-shaped restricting member 56 extending from the top surface (51a) towards the bottom surface side (Z2 side). The restricting member 56 has a surface that extends within a plane (XY plane) substantially orthogonal to the connection direction "Z". Figures 6 to 8As clearly shown, the limiting member 56 covers the outer surface near the corresponding mounting portion 232 from the outside on the surface (XZ plane) intersecting the width direction "Y". In other words, it overlaps with the outer surface near the corresponding mounting portion 232 when viewed from the side, thereby limiting the widening of the corresponding mounting portion 232 in the width direction "Y". As a result, even if a force is applied to the corresponding mounting portion 232 to widen it in the width direction, such as when the plug connector 1 is accidentally dropped, the widening of the corresponding mounting portion 232 is limited, thereby preventing the operating lever 20 from falling off the housing 10. In addition, in the illustrated example, the limiting member 56 is configured to always limit the outer surface near the corresponding mounting portion 232, but it is not necessary to configure it like this. As long as it is positioned on the top surface side (refer to the top surface side) according to the user's specifications, it is not necessary to configure it like this. Figure 8 etc.), bottom side (refer to) Figure 6 (etc.) and between the top and bottom surfaces (refer to) Figure 7 It is sufficient to apply a restriction at at least any one of the positions in the given list. For example, such as Figure 8 As shown, it can also be configured to cover the operating lever 20 only when it is positioned on the top surface side (Z1 side), in other words, only when there is a greater risk of the operating lever 20 falling off the housing 10. Furthermore, the limiting member only needs to be able to limit the corresponding mounting portion 232 from widening in the width direction "Y". Therefore, although not specifically shown, it can also be configured to form a slit between the protruding member 15 and the third wall 13A or the fourth wall 13B, and make the slit function as a limiting member.

[0072] The terminals (first terminals) disposed on the housing 10 include a power terminal 80, a signal terminal 86, and a signal terminal 87. At the power terminal 80 ( Figure 4 , Figure 5 ) and signal terminal 86 ( Figure 3 The ends of the cables 2A and 8A are respectively installed at one end of the cable. Similarly, at the signal terminal 87, Figure 3 , Figure 5 The end of the cable 2B is installed on one side.

[0073] Reference Figure 5 And others Figures 9 to 12 The first and second connection modules will be described below. Figure 9 It shows Figure 4 The exploded perspective view shows a top view of the plug-type connector; in other words, it shows a top view of the plug-type connector after the cover has been removed to open the storage space. Additionally, in... Figure 10 as well as Figure 11 China respectively utilize Figure 9 The AA-line cross-sectional view illustrates the method of storing the first and second connecting modules, to which the cables are connected, into the storage space. Additionally, in... Figure 12The diagram shows schematic cross-sections of the same plug-type connector with the first and second connecting modules placed in the storage space and the cover installed to close the storage space.

[0074] The first connecting module 35 is housed in a storage space 103 located on the side of the first wall 11 (X1 side) in the length direction "X". The first connecting module 35 has a relatively small thickness in the connecting direction "Z" and a relatively large surface area in the plane intersecting the connecting direction "Z" (XY plane). In addition to multiple mounting slots 350, the first connecting module 35 also has multiple terminal mounting holes 786. The mounting slots 350 can be used to mount terminals horizontally relative to the intersecting surface, and the terminal mounting holes 786 can be used to mount terminals vertically relative to the intersecting surface, in other words, along the connecting direction "X". Power terminal 80 (see reference) Figure 4 , Figure 5 , Figure 9 More specifically, the first connecting module 35, installed at one end of the cable 2A, is positioned in the mounting slot 350 with the core wire 5 exposed after removing the outer sheath and inner shielding member 3a. Then, the first connecting module 35, installed at one end of the cable 2A, is stored in the storage space 103 from the top surface (Z1 side) to the bottom surface (Z2 side). As described above, the signal terminal 86 is vertically mounted in the terminal mounting hole 786. Therefore, when the first connecting module 35 is stored in the storage space 103, both the first connecting module 35 and the cable 2A protrude significantly towards the top surface (Z1 side). However, by leaving the top surface open, a large space is ensured on the top surface (Z1 side) of the storage space 104, allowing the user to perform storage operations without problems. Furthermore, as described above, the height of the wall on the first wall 11 side (X1 side) of the housing 10 is set to decrease towards the bottom surface (Z2 side), thus allowing the user to easily perform storage operations.

[0075] The second connecting module 36 is housed in a storage space 104 located on the side of the first wall 11 (X1 side) in the longitudinal direction "X". The second connecting module 36 has a relatively large thickness in the connecting direction "Z" and a relatively small surface area in the plane intersecting the connecting direction "Z" (XY plane). The second connecting module 36 is provided with a plurality of terminal mounting holes 787, which allow terminals to be mounted perpendicularly to the intersecting plane, in other words, along the connecting direction "X". Signal terminal 87 (see reference) Figure 3 , Figure 5 , Figures 9 to 11 At one end of the cable 2B, more specifically, in the state where the core wire 5b is exposed after removing the outer sheath and inner shielding member 3b, the terminal mounting hole 787 is provided, and then, as follows Figure 10 as well as Figure 11As clearly shown, the second connecting module 36, installed at one end of the cable 2B, is housed in the housing space 104 from the top surface (Z1 side) to the bottom surface (Z2 side). As described above, the signal terminal 87 is vertically mounted in the terminal mounting hole 787. As a result, the second connecting module 36 has a relatively larger thickness in the connection direction "Z" compared to the first connecting module 35. Therefore, when the second connecting module 36 is housed in the housing space 104, the second connecting module 36 and the cable 2B protrude significantly towards the top surface (Z1 side). However, by leaving the top surface open, a larger space is ensured on the top surface (Z1 side) of the housing space 104, allowing the user to easily address this issue. Furthermore, as described above, the top 11a of the top surface side (Z1 side) of the first wall 11 is positioned further to the bottom surface side (Z2 side) in the length direction "X" than the top 13a, 13b of the top surface side (Z1 side) of the third wall 13A and the fourth wall 13B located on the first wall 11 side (X1 side). In addition, the height of the wall on the first wall 11 side (X1 side) of the housing 10 is set to decrease as it moves toward the bottom surface side (Z2 side). Therefore, the user can easily perform storage operations while reducing the possibility of interference between the second connection module 36 and the first wall 11 or the fifth wall 14A and the sixth wall 14B. Furthermore, when storing the second connecting module 36 in the storage space 104, in order to minimize the excess length of the core wire 5b connected to the second connecting module 36, the second connecting module 36 is rotated. More specifically, firstly, the top plate side (Z1 side) of the second connecting module 36 is tilted towards the second wall 12, and its bottom surface side (Z2 side) is tilted towards the first wall 11. Then, the second connecting module 36 is rotated in such a manner that the top plate side (Z1 side) is tilted towards the first wall 11 and its bottom surface side (Z2 side) is tilted towards the second wall 12, thereby storing the second connecting module 36 in the storage space 104 (see reference). Figure 10 However, as described above, the top 11a of the top surface side (Z1 side) of the first wall 11 is positioned closer to the bottom surface side (Z2 side). Furthermore, the height of the wall on the first wall 11 side (X1 side) of the housing 10 is set to decrease as it moves toward the bottom surface side (Z2 side). Therefore, during this rotation operation, the storage operation can be performed while reducing the possibility of interference between the second connecting module 36 and the first wall 11 or the fifth wall 14A and the sixth wall 14B.

[0076] After that, as Figure 12 As shown, the top side of the open storage space 104 is sealed by installing the cover 50.

[0077] Reference Figure 5 as well as Figures 10 to 12 And others Figures 13 to 16The first shielding member and the second shielding member will be described below. The first shielding member 41 and the second shielding member 42 are formed by punching and bending metal plates, and have a left-right symmetrical shape in the width direction "Y". Figures 13 to 16 The details of the second shielding member and the method of setting the second shielding member relative to the cable (2B) are shown together. Figure 13 This is a perspective view showing the second shielding member positioned in front of the cable. Figure 14 These are the side view and front view in the same state. Figure 15 This is a perspective view showing the second shielding member positioned after the cable. Figure 16 These are the side view and front view in the same state. However, for ease of explanation, in Figure 14 as well as Figure 16 The front view shows the cross-section of cable 2B at the location where the second shielding member 42 is provided. Furthermore, although a detailed description of the first shielding member is omitted, the first shielding member differs from the second shielding member only in size; they have the same structure and function, and therefore can be considered in the same manner as the second shielding member. For reference, in Figure 5 In the process, for the constituent parts of the first shielding member, the reference number of the 420 series in the second shielding member 42 is changed to the 410 series and the reference number is marked as much as possible.

[0078] like Figures 13 to 16 As clearly shown, the second shielding member 42 includes: a first surface 420, which, when housed in the housing space 102, forms a surface intersecting the connection direction "Z" (XY surface); and a second surface 424A and a third surface 424B, which, when housed in the housing space 102, form a surface intersecting the width direction "Y" (XZ surface), and are arranged opposite to each other in the width direction "Y". The cable 2B is positioned in the cable placement space 40 surrounded by the first surface 420, the second surface 424A, and the third surface 424B. At this time, the second shielding member 42 covers the surfaces of the inner shielding members 3a and 3b except for the bottom surface (Z2 side).

[0079] The first surface 420 is provided with: first elastic contact portions 421A and 421B, which are formed by bending a portion of them outward toward the cable mounting space 40; and a second elastic contact portion 422, which is formed by bending a portion of it inward toward the cable mounting space 40. The first elastic contact portions 421A and 421B are arranged adjacent to each other in the width direction "Y" with the second elastic contact portion 422 sandwiched between them. The first surface 420 is also provided with an operating portion 423 protruding outward toward the cable mounting space 40. The operating portion 423 can be used, for example, when removing the second shielding member 42 from the storage space 102.

[0080] The second surfaces 424A and 424B are respectively provided with: first elastic contact portions 425A and 425B, which are formed by bending a portion of the first elastic contact portions 425A and 425B outwards towards the cable mounting space 40; and second elastic contact portions 426A and 426B, which are formed by bending a portion of the second elastic contact portions 426A and 426B inwards towards the cable mounting space 40.

[0081] When the first shielding member 41 and the second shielding member 42 are housed in the housing spaces 101 and 102, cables 2A and 2B are pre-housed in the housing spaces 101 and 102, respectively. Cables 2A and 2B pass through the first through hole 121 and the second through hole 122 respectively in the second wall 12. Figure 5 In the state of [unclear], the cables 2A and 2B extend along the length direction "X" from the second wall 12 side (X2 side) to the first wall 11 side (X1 side), with one end of each cable exposed by removing the outer sheath, exposing the internal shielding members 3a and 3b. The first shielding member 41 and the second shielding member 42 are stored in the storage spaces 101 and 102 from the top surface (Z1 side) to the bottom surface (Z2 side) through the open top surface (Z1 side). When stored in the storage spaces 101 and 102, they cover the exposed internal shielding members 3a and 3b by three sides. The stored first shielding member 41 and the second shielding member 42 are in contact with the internal shielding members 3a and 3b and with a designated portion of the outer casing 10. Furthermore, when the outer casing 10 is closed by the cover 50, they are in contact with the cover 50 to perform the shielding function. Thus, by using the first shielding member 41 and the second shielding member 42, shielding function can be easily provided without cumbersome operations such as passing the cable through a loop.

[0082] In order to position the first shielding member 41 and the second shielding member 42 at the specified positions in the storage spaces 101 and 102, positioning units 101a with a specified shape are provided in the storage spaces 101 and 102 (see reference). Figure 5 ), 102a (refer to Figures 10 to 12 Correspondingly, the first shielding member 41 and the second shielding member 42 are respectively provided with corresponding positioning units 430 and 440 having shapes corresponding to a predetermined shape. In the illustrated example, protrusions are respectively provided as positioning units 101a and 102a, and recesses are respectively provided as corresponding positioning units 430 and 440.

[0083] Reference Figures 13 to 16 as well as Figure 17 The contact states between the first elastic contact portion and the second elastic contact portion and the internal shielding component, the outer shell and the cover are described. Figure 17 This is shown with the cables disconnected. Figure 8 The rear view of the plug connector shown.

[0084] When the second shielding member 42 is housed in the storage space 102 and the outer shell 10 is subsequently closed by the cover 50, the first elastic contact portions 421A and 421B provided on the first surface 420 of the second shielding member 42 contact the cover 50 at their contact point 421a, and the second elastic contact piece 422 contacts the inner shielding member 3b at its contact point 422a.

[0085] On the other hand, the first elastic contact portion 425A provided on the second surfaces 424A and 424B of the second shielding member 42 contacts the shielding plate 16 of the outer shell 10 at its contact point 425a. On the other hand, the first elastic contact portion 425B contacts the third wall 13B of the outer shell 10 at its contact point 425b. In addition, the second elastic contact portions 426A and 426B contact the inner shielding member 3b at their contacts 426a and 426b.

[0086] Similarly, when the first shielding member 41 is housed in the storage space 101 and the outer shell 10 is subsequently closed by the cover 50, the first elastic contact portions 411A and 411B provided on the first surface 410 of the first shielding member 41 contact the cover 50 at their contact point 411a, and the second elastic contact piece 412 contacts the inner shielding member 3a at its contact point 412a.

[0087] On the other hand, the first elastic contact portion 415A, which is provided on the second surfaces 414A and 414B of the first shielding member 41, contacts the third wall 13A of the outer shell 10 at its contact point 415a. On the other hand, the first elastic contact portion 415B contacts the shielding plate 16 of the outer shell 10 at its contact point 415b. In addition, the second elastic contact portions 416A and 416B contact the inner shielding member 3a at their contacts 416a and 416b.

[0088] Thus, the first shielding member 41 and the second shielding member 42 contact the inner shielding members 3a and 3b at three points respectively. Therefore, even if the position of the cable stored in the storage space shifts due to impact, the contact state between the shielding member and the inner shielding member can be maintained. Furthermore, since the first shielding member 41 and the second shielding member 42 are respectively in contact with both the outer shell 10 and the cover 50, the shielding performance can be improved. In addition, even if the size of the first shielding member 41 is different from the diameter of the inner shielding member 3a, or the size of the second shielding member 42 is different from the diameter of the inner shielding member 3b, the second elastic contact piece 412 and the second elastic contact portions 416A and 416B are each configured to have a predetermined length for elastic contact with the inner shielding member 3a, and the second elastic contact piece 422 and the second elastic contact portions 426A and 426B are each configured to have a predetermined length for elastic contact with the inner shielding member 3b. Therefore, the difference between the size of the shielding member and the diameter of the inner shielding member can be easily accommodated.

[0089] Reference Figure 5 as well as Figure 17 The fixing components are described below. The fixing components include a first fixing member 31 and a second fixing member 32 arranged in the width direction "Y". The first fixing member 31 is only larger than the second fixing member 32, and they have the same structure and function.

[0090] The first fastener 31 is threadedly fixed to a cylindrical first outlet portion 123 extending from the second wall 12 of the housing 10. A generally circular first through-hole 121 with a relatively large diameter is provided in the second wall 12 of the housing 10, allowing the cable 2A to pass through. The first through-hole 121 communicates with the first outlet portion 123, and one end of the cable 2A extends longitudinally "X" from the second wall 12 side (X2 side) to the first wall 11 side (X1 side) while passing through both the first through-hole 121 and the first outlet portion 123. When storing one end of the cable 2A in the storage space 101 located on the second wall 12 side (X2 side), it is necessary to temporarily move the cable 2A, which has been removed from the first through-hole 121, towards the top surface side (Z1 side). Although this operation is cumbersome, it can be handled using the space above the storage space 101 created by opening the top surface side. The first fastener 31 includes a first clamping member 310 and a washer 312 as peripheral components. The first clamping member 310 is disposed on the outer sheath of the cable 2A with the cable 2A passing through it via a washer 312. When the first fixing member 31 is fixed to the first guide portion 123, the first clamping member 310 secures the cable 2A using a plurality of clamping pieces 310b that are separated from each other by a slit 310a. The washer 312, together with the first clamping member 310, is secured to the cable 2A to provide a waterproof function.

[0091] The second fastener 32 has the same structure as the first fastener 31. The second fastener 32 is threaded onto a cylindrical second outlet portion 124 extending from the second wall 12 of the housing 10. A generally circular second through hole 122 with a relatively small diameter is provided in the second wall 12 of the housing 10, allowing the cable 2B to pass through. This second through hole 122 is separated from the first through hole 121 at least in the width direction "Y". By providing a through hole with a small diameter in this way, the excess space between the cable and the through hole can be reduced, and the shielding performance can be improved even for small-diameter cables. The second through hole 122 is provided in communication with the second outlet portion 124, and one end of the cable 2B extends from the second wall 12 side (X2 side) to the first wall 11 side (X1 side) in the length direction "X" while passing through both the second through hole 122 and the second outlet portion 124. When storing one end of cable 2B in the storage space 102 located on the side of the second wall 12 (X2 side), it is necessary to temporarily move cable 2B, which is taken out from the second through hole 122, towards the top surface (Z1 side), but if Figure 17As clearly shown, the center (p) of the second through hole 122 is positioned further towards the top surface (Z1 side) in the connection direction "Z" than the center (q) of the first through hole 121. In other words, the second through hole 122 is positioned offset towards the top surface (Z1 side). Therefore, it is easier to move the cable 2B taken out from the first through hole 121 towards the top surface (Z1 side) of the storage space 102, and it also simplifies the subsequent storage operation (installation operation) of the cable 2B into the storage space 102. Furthermore, by positioning the second through hole 122 offset towards the top surface (Z1 side), the first through hole 121 and the second through hole 122 can be configured to be closer in the width direction "Y". As a result, the distance in the width direction "Y" between the first fixing member 31 and the second fixing member 32 can be further reduced, thereby further reducing the size of the cable connector 1 in the width direction "Y". More specifically, by positioning the second through hole 122 offset towards the top surface (Z1 side), the center "p" of the first through hole 121 and the center "q" of the second through hole 122 are positioned at different positions in the connection direction "Z". At this time, a gap is created between the center "q" of the first through hole 121 and the center "p" of the second through hole 122. This gap is used to bring the first through hole 121 and the second through hole 122 closer together. Therefore, the distance "m" between the centers of the first through hole 121 and the second through hole 122 in the width direction "Y" is smaller than the distance between the centers "p" of the first through hole 121 and the center "q" of the second through hole 122 when they are at the same position in the connection direction "Z". By setting it in this state, the size of the cable connector 1 in the width direction "Y" can be further reduced. Preferably, the top 122a of the top surface side "Z1" of the second through hole 122 is positioned at the same position as the top 121a of the top surface side "Z1" of the first through hole 121, or positioned further to the bottom surface side (Z2 side) than the top 121a of the first through hole 121, so as not to increase the size of the cable connector 1 in the connection direction "Z". The second fixing member 32, like the first fixing member 31, includes a second clamping member 320 and a washer 322 as peripheral members, and is installed via the second fixing member 32 in the same way as the first clamping member 310 and the washer 312.

[0092] Reference Figure 1 as well as Figure 18 The socket connector 6 will be described below. Figure 18This is an exploded perspective view showing the receptacle connector 6 together with the cable. The receptacle connector 6 includes: a conductive base 60; a conductive connecting member 64 connected to the housing 10 of the plug connector 1; locking members 63A and 63B corresponding to the locking portion (230) of the plug connector 1; a plurality of terminals, namely power terminals 90, signal terminals 96 and signal terminals 97 (second terminals); and resin first connecting modules 71 and second connecting modules 72 for providing the terminals to the connecting member 64.

[0093] The base 60 is a flat plate-shaped component that is fixed to the housing and wall surface (not shown). Threaded holes 60a for fixing are provided at the four corners of the base 60 in a through-hole manner.

[0094] The connecting member 64 is a frame-shaped member disposed on one side of the base 60. More specifically, it is a frame-shaped member disposed on the side opposite to the connecting side (Z1 side) of the plug connector 1, or in other words, the side (Z2 side) where the socket connector 6 is fixed to the housing, etc. The connecting member 64 is disposed in a state that protrudes from the bottom side (Z2 side) to the top side (Z1 side) and is inserted into the opening 110 of the housing 10 of the plug connector 1 (see reference). Figure 3 When inserted into the opening 110, the connecting member 64 is secured to the housing 10 by the locking part 64a provided on its peripheral surface. The connecting member 64 is provided with two storage spaces 641 and 642 separated by the partition part 646.

[0095] Locking members 63A and 63B are members that stand upright from the bottom surface (Z2 side) to the top surface (Z1 side) on the same surface as the surface where the connecting member 64 is provided, and are positioned to clamp the connecting member 64 in the width direction "Y". At the end of the top surface (Z1 side) of each locking member 63A and 63B, a protrusion 630 is provided that protrudes toward the connecting member 64 in the width direction "Y". Thus, in the width direction "Y", an insertion space 631 is formed between the connecting member 64 and the locking members 63A and 63B, respectively, and the side of the insertion space 631 that connects to the plug connector 1 (Z1 side) is blocked by the protrusion 630. When the housing 10 is connected to the connecting member 64, when the operating lever 20 is... Figure 8 The angle position shown (top side) is towards Figure 6 The angle position shown (bottom side) is reached by rotating. Figure 6 When the angle position shown (bottom side) is reached, the protrusion 230 of the arm 23 of the operating lever 20 enters the insertion space 631, thereby locking the housing 10 into the socket connector 6.

[0096] The power terminal 90, signal terminal 96, and signal terminal 97 are respectively installed at one end of the cable 7, etc. When the housing 10 is connected to the connecting member 64, the power terminal 90, signal terminal 96, and signal terminal 97 are electrically connected to the power terminal 80, signal terminal 86, and signal terminal 87 of the plug connector 1, respectively.

[0097] The first connection module 71, with power terminals 90 and signal terminals 96 provided, is disposed in the storage space 641 of the connection member 64 from the top side (Z1 side) to the bottom side (Z2 side). When the plug connector 1 is connected to the socket connector 6, the connection module 35 of the plug connector 1, which is connected to the end (core wire) of the cable 2A, is further connected to the first connection module 71 from the top side (Z1 side) to the bottom side (Z2 side).

[0098] On the other hand, with the signal terminal 97 provided, the second connection module 72 is disposed in the storage space 642 of the connection member 64 from the top side (Z1 side) to the bottom side (Z2 side). When the plug connector 1 is connected to the socket connector 6, the connection module 36 of the plug connector 1, which is connected to the end (core wire 5b) of the cable 2B, is further connected to the second connection module 72 from the top side (Z1 side) to the bottom side (Z2 side).

[0099] exist Figure 19 The image shows a perspective view of the first connection module and its state before installation of the power supply terminals on the first connection module. Furthermore, in... Figure 20 The top view shows the configured state. For clarity, these figures show the cable 7 connected to the power terminal. On the first connection module 71, power terminal 90 and signal terminal 96 (see reference) are configured. Figure 18 The device is provided with multiple through holes 790A, 790B, and 786. Through holes 790A and 790B all have the same structure, and a power terminal 90 is inserted and disposed in each through hole 790A and 790B in a predetermined orientation. Similarly, a signal terminal 96 is inserted and disposed in each through hole 786 in a predetermined orientation. Specifically, power terminals 90A and 90B are inserted into through holes 790A and 790B in predetermined directions. In the illustrated example, power terminals 90A and 90B are inserted into through holes 790A and 790B respectively, with a circumferential "r" angle between them, differing by 180 degrees. However, as described below, the power terminal 90A can also be inserted into the through hole 790A with the power terminal 90B facing the direction after being rotated 180 degrees in the circumferential direction "r". Similarly, the power terminal 90B can also be inserted into the through hole 790B with the power terminal 90A facing the direction after being rotated 180 degrees in the circumferential direction "r".

[0100] Figure 21 as well as Figure 22 The diagrams show perspective views of the power terminals from different angles. Figure 23 A rear view of the power supply terminals is shown. Figure 24 Showing its side view, Figure 25 The front view is shown. The power terminal 90 is formed by punching, bending, etc., a metal plate. The power terminal 90 includes: cable fixing members 91 and 92 with a generally rectangular cross-section, fixed to the cable 7; a contact member 93 disposed on the side opposite to the cable fixing members 91 and 92 in the longitudinal direction "Z" of the power terminal 90; and an intermediate member 94 with a generally rectangular cross-section disposed between the contact member 93 and the cable fixing members 91 and 92. When the power terminal 90 is disposed in the through hole 790, the longitudinal direction of the power terminal 90 is the same as the connection direction "Z" of the plug connector 1 and the socket connector 6. The cable fixing member 91 is fixed to the shielding layer 8 of the cable 7 (described later). Figure 30 , Figure 31 The cable fixing component 92 is fixed to the outer sheath 7a of the cable 7 (described later). Figure 30 , Figure 31 These structures are the same as those for general cable fixing components, therefore, they will not be described in detail here.

[0101] Contact member 93 is located at the front end of power terminal 90 and can contact power terminal 80 of plug connector 1 when plug connector 1 is connected to socket connector 6. The front end of the contact portion of power terminal 80 is divided into two parts, and contact member 93 is connected in a clamped state after the divided contact portion. To ensure strength, contact member 93 is formed into a plate-shaped double-layer structure by bending and overlapping the plate. When power terminal 90 is provided in the first connection module, contact member 93, together with other contact members, is configured in the "XY plane" orthogonal to the connection direction "Z" so that its plate surface is approximately parallel to the plate surfaces of other contact members, and when plug connector 1 is connected to socket connector 6, it is connected simultaneously with power terminal 90 one by one, along with other contact members 93.

[0102] The outer peripheral surface 94a of the intermediate member 94 has a polygonal cross section, which, in the illustrated example, has a rectangular cross section.

[0103] On the outer peripheral surface 94a of the intermediate member 94, there is a pair of engaging portions (941, 942) consisting of a main engaging portion (941) and a secondary engaging portion (942). The pair of engaging portions (941, 942) are arranged in a relatively opposite configuration, that is, they are separated from each other by approximately 180 degrees in the circumferential direction "r" of the outer peripheral surface 94a of the intermediate member 94, and are respectively arranged in the length direction "Z". Furthermore, they are arranged to protrude outward (in the "Y1" or "Y2" direction) from the outer peripheral surface 94a of the intermediate member 94 as they move away from the contact member 93 side toward the cable fixing members 91, 92 side (Z2 direction). In the illustrated example, a pair of engaging portions are formed by bending strip-shaped pieces outwards so that their front ends (ends) 941a and 942a are the portions furthest from the outer peripheral surface 94a of the intermediate member 94. The strip-shaped pieces are formed by creating elongated, approximately C-shaped slits in a metal plate, extending in a "Z" direction along their length. These strips respectively constitute elastically displaceable locking pieces 941 and 942.

[0104] A protrusion 944 is also provided on the outer peripheral surface 94a of the intermediate member 94. The protrusion 944 is provided to protrude outward from the outer peripheral surface 94a of the intermediate member 94 in a direction intersecting the length direction "Z" ("X1" or "X2" direction). In the illustrated example, the protrusion 944 is provided as part of a folded portion 943 formed by folding the metal plate back 180 degrees toward the cable fixing members 91, 92, and is provided as a shorter strip member protruding from the outer peripheral surface 94a of the intermediate member 94 in the "X1" direction. In addition, in the illustrated example, only one protrusion 944 is provided, but it is also possible to provide a pair of protrusions (not shown) that are arranged opposite each other, that is, a pair of protrusions that are approximately 180 degrees apart in the circumferential direction "r" of the outer peripheral surface 94a.

[0105] Figure 26 This shows a top view of the first connection module 71 as seen from the connection side (Z1 side) between the plug connector 1 and the socket connector 6. Figure 27 This shows a top view of the first connection module 71 viewed from the side opposite to the connection side (Z1 side) (Z2 side), in other words, from the insertion side of the power terminal 90 and signal terminal 86 relative to the through holes 790 and 786 of the first connection module 71. Additionally, Figure 28 as well as Figure 29 The images shown are viewed from different angles. Figure 27 The top view shown is a perspective view.

[0106] The power terminal 90 is inserted into the through hole 790 of the first connection module 71 from the side opposite to the connection side (Z1 side) of the housing 10 and the connection member 64 (Z2 side) towards the connection side (Z1 side) (Z1), in the order of contact member 93, intermediate member 94, cable fixing member 91, 92, thereby being provided in the through hole 790 of the first connection module 71.

[0107] The inner peripheral surface 790a of the through hole 790 and the outer peripheral surface 94a of the intermediate member 94 have polygonal cross-sections, which are rectangular in the illustrated example. As a result, the power terminal 90 is disposed in the through hole 786 in a predetermined direction without requiring a large space for locking the terminal, which is suitable for miniaturization.

[0108] A pair of corresponding engaging portions, namely protrusions 741 and 742, are provided on the inner peripheral surface 790a of the through hole 790, corresponding to a pair of engaging portions (941, 942) provided on the outer peripheral surface 94a of the intermediate member 94. The protrusions 741 and 742 are arranged in a relatively opposite configuration, that is, they are arranged approximately 180 degrees apart from each other in the circumferential direction "r" of the inner peripheral surface 790a. This pair of corresponding engaging portions (741, 742) and the adjacent pair of corresponding engaging portions are arranged face-to-face in the relative direction "Y" of the pair of corresponding engaging portions (741, 742). The relative direction "Y" is the same as the width direction "Y". The first connecting module 71 has a predetermined length in the width direction "Y", so it can be configured in a suitable state. These protrusions 741 and 742 are respectively provided in the following state: when the power terminal 90 is inserted into the through hole 790, the ends 941a and 942a of the pair of engaging portions (941 and 942) located at the position furthest from the outer peripheral surface 94a of the intermediate member 94 protrude further into the through hole 790.

[0109] A pair of recesses 744A and 744B are also provided on the inner peripheral surface 790a of the through hole 790. These recesses 744A and 744B are arranged opposite to each other, that is, they are set apart from each other by approximately 180 degrees in the circumferential direction "r" of the inner peripheral surface 790a. The pair of recesses 744A and 744B are recessed outward from the inner peripheral surface 790a of the through hole 790 in a direction intersecting the length direction "Z" ("X1" or "X2" direction).

[0110] Reference Figure 30 as well as Figure 31 The engaging action of a pair of engaging portions (941, 942) provided on the outer peripheral surface 94a of the intermediate member 94 and a pair of corresponding engaging portions (741, 742) provided on the inner peripheral surface 790a of the through hole 790 will be explained. Figure 30 and Figure 31 They are shown respectively Figure 20AA line section view and Figure 20 The figures show a BB-line cross-sectional view. As can be seen from these figures, when the power terminal 90 is inserted into the through hole 790, a pair of engaging portions (941, 942) on the outer peripheral surface 94a of the intermediate member 94 engage with a pair of corresponding engaging portions (741, 742) on the through hole 790. More specifically, when the strip-shaped pieces 941, 942 on the outer peripheral surface 94a of the intermediate member 94 are inserted into the through hole 790 from the side opposite to the connection side (Z1 side) of the housing 10 and the connecting member 64 (Z2 side) towards the connection side (Z1 side) (Z1), their front ends 941a, 942a abut against the inner peripheral surface 790a of the through hole 790 at their front ends 941a, 942a, and elastically displace inward toward the outer peripheral surface 94a of the intermediate member 94. Subsequently, when the aforementioned front ends 941a and 942a pass over a pair of corresponding locking portions, i.e., protrusions 741 and 742, provided on the inner peripheral surface 790a of the through hole 790, the outer shell 10 and the connecting member 64 of these protrusions 741 and 742 are locked onto the side surfaces 741a and 742a of the protrusions 741 and 742. As a result, it is possible to prevent the power terminal 90 from dislodging from the through hole 790 from the connection side of the outer shell 10 and the connecting member 64 toward the side opposite to the connection side. In this case, the front ends 941a and 942a are locked onto either of the side surfaces 741a and 742a of the protrusions 741 and 742, respectively. Furthermore, the engaging portion (941) provided on the intermediate member 94 can engage with either the corresponding engaging portion (741) provided on the inner peripheral surface 790a of the through hole 790 or the corresponding engaging portion (742). Similarly, the engaging portion (942) provided on the intermediate member 94 can engage with either the corresponding engaging portion (742) provided on the inner peripheral surface 790a of the through hole 790 or the corresponding engaging portion (741). Therefore, only one engaging portion is required, and it is not necessary to provide a pair of engaging portions (941, 942). In addition, according to this structure, the power terminal 90 only needs to be rotated to the left or right by a maximum of about 90 degrees in the circumferential "r" direction to engage with the through hole 790 of the first connection module 71, which makes the cable installation operation easier.

[0111] Reference Figure 32 The interlocking action between the protrusion 944 provided in the intermediate member 94 and the recesses 744A and 744B provided in the inner peripheral surface 790a of the through hole 790 will be explained. Figure 32 for Figure 20The diagram shows a cross-sectional view along line CC. When the power terminal 90 is inserted into the through hole 790, the protrusion 944 engages with either of the pair of recesses 744A and 744B provided on the inner peripheral surface 790a of the through hole 790. In other words, the power terminal 90 cannot be inserted into the through hole 790 unless the protrusion 944 is engaged with either of the pair of recesses 744A and 744B provided on the inner peripheral surface 790a of the through hole 790. Therefore, through the action of these protrusions 944 and recesses 744A and 744B, the orientation of the power terminal 90 when inserted into the through hole 790 can be determined, and furthermore, rotation of the power terminal 90 inside the through hole 790 can be prevented after insertion.

[0112] Those skilled in the art to which this invention pertains will be able to conceive of many variations or other embodiments of the invention based on the teachings shown in the foregoing description, and it will be apparent to those skilled in the art that variations and modifications can be made to the invention without departing from its scope or spirit. Therefore, it should be understood that the invention is not limited to the specific embodiments disclosed, and variations and other embodiments are intended to be included within the scope of the appended claims.

[0113] For example, in the example described above, the pair of engaging portions (941, 942) are elastically deformable as elastic retaining pieces, but the pair of corresponding engaging portions (741, 742) can also be elastically deformable. In other words, elastic engaging portions can be provided in the through holes of the connecting module, and corresponding engaging portions can be provided in the power terminals.
