Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the conventional technology as described above, it is not easy to insert and remove the electric cable with respect to the housing while bending the electric cable within the housing, and the workability is likely to deteriorate.

[0005] Therefore, one of the problems to be solved by the present disclosure is to provide a cable connector with a novel structure that can improve the workability of inserting and removing the electric cable with respect to the housing.

Means for Solving the Problems

[0006] The cable connector according to this disclosure comprises a cylindrical housing configured to accommodate a terminal portion connected to the end of an electrical cable, having a first opening on one end into which the electrical cable is inserted and a second opening on the other end that exposes the terminal portion connected to the end of the electrical cable inserted through the first opening, and a cover coupled to the housing so as to cover the first opening of the housing, wherein the coupled housing and cover constitute a substantially L-shaped internal space in a side view, and in a cross-section of the housing in a side view along the electrical cable passing through the first opening, the first line along the first opening is inclined such that it moves away from the second line in a first direction perpendicular to the second line along the second opening, and approaches the end of the electrical cable in a second direction parallel to the second line as it moves away from the second line. [Effects of the Invention]

[0009] <Embodiment> The embodiments of this disclosure will be described below with reference to the drawings. The configurations of the embodiments described below, as well as the functions and effects brought about by such configurations, are merely examples and are not limited to the contents described below.

[0010] Furthermore, in this disclosure, ordinal numbers such as "1st" and "2nd" are assigned for convenience to distinguish parts or components, and do not indicate a specific priority.

[0011] In addition, in each figure of this disclosure, the X direction corresponds to the front-to-back direction of the plug connector 100 (the direction in which the electrical cable 300 extends within the cover 130 of the plug connector 100). The Y and Z directions correspond to the left-to-right direction (width direction) and the up-to-down direction (thickness direction) of the plug connector 100, respectively.

[0012] Figure 1 is a perspective view showing a connector device according to an embodiment, and Figure 2 is a perspective view showing the connector device according to the embodiment in a separated state. The connector device according to the embodiment is used to realize the input and output of electrical signals to and from electrical equipment such as a motor.

[0013] As shown in Figures 1 and 2, the connector device according to the embodiment comprises a plug connector 100 and a receptacle connector 200, which are examples of the "cable connector" of this disclosure. The plug connector 100 is used when connected to an electrical cable 300, and the receptacle connector 200 is used when installed on the surface of the housing of an electrical device. In this embodiment, two electrical cables 300 are provided, and the two electrical cables 300 are classified as, for example, a first electrical cable for transmitting data such as control signals and a second electrical cable for transmitting power signals.

[0014] The plug connector 100 and the receptacle connector 200, when mated together, enable the input of electrical signals to electrical equipment via the electrical cable 300, or the output of electrical signals from electrical equipment via the electrical cable 300. Figure 1 shows the plug connector 100 and the receptacle connector 200 in a mated state, while Figure 2 shows the plug connector 100 and the receptacle connector 200 separated from each other when mated.

[0015] Here, the state in which the plug connector 100 and the receptacle connector 200 are mated together (see Figure 1) and the state in which the plug connector 100 and the receptacle connector 200 are disassembled (see Figure 2) can be switched using an operating lever 120 attached to the plug connector 100.

[0016] The operating lever 120 has a substantially U-shaped strip extending from one side to the other of the plug connector 100 (more specifically, the housing 110 described later), and is configured to rotate by a predetermined angle (for example, 90 degrees) around a pivot shaft portion 121 provided on the side of the housing 110. When the operating lever 120 is rotated to the front position of the housing 110 (see Figure 1), the mating of the plug connector 100 and the receptacle connector 200 is maintained, and when the operating lever 120 is rotated to the top position of the housing 110 (see Figure 2), the mating of the plug connector 100 and the receptacle connector 200 is released.

[0017] As shown in FIG. 2, the receptacle connector 200 includes a connection portion 210 provided with terminal holes 211 and 212 into which a terminal portion 410 (see FIG. 3 etc.) on the plug connector 100 side described later is inserted, and a claw portion 220 that fixes the housing 110 by catching on the housing 110 when the plug connector 100 and the receptacle connector 200 are fitted to each other. The terminal holes 211 and 212 are formed by mounting a terminal portion (not shown) on the receptacle connector 200 side to the connection portion 210.

[0018] Also, as shown in FIGS. 1 and 2, the plug connector 100 includes, in addition to the above-described operation lever 120, a cover 130, a seal member 140, and a cap member 150. Hereinafter, referring to FIGS. 3 to 6, these configurations of the plug connector 100 will be described in more detail.

[0019] FIG. 3 is an exploded perspective view of the plug connector 100 according to the embodiment. FIG. 4 is a cross-sectional view taken along the A-A cutting line of the plug connector 100 shown in FIG. 1. FIG. 5 is a cross-sectional view showing the housing 110 extracted from FIG. 4. FIG. 6 is a cross-sectional view taken along the B-B cutting line of the plug connector 100 shown in FIG. 1.

[0020] As shown in FIG. 3, the plug connector 100 is configured as a combination of a housing 110 to which an operation lever 120 is attached, a cover 130 that is coupled to the housing 110 by a screw 500 with the seal member 140 interposed therebetween, a cap member 150 that is coupled to the back side of the cover 130 via a gasket 151 and a clamp 152, and a terminal portion 410 including terminals 411 and a case 412 housed in the housing 110. In FIG. 3, for simplicity, the illustration of the electric cable 300 is omitted.

[0021] Furthermore, as shown in Figure 4, the housing 110 is configured to accommodate the entire terminal portion 410 connected to the internal wiring 310 protruding from the end of the electrical cable 300, where the braid 320 is exposed at the end. In this embodiment, the housing 110 and the cover 130 are joined together to form an internal space that is approximately L-shaped in side view inside the joined housing 110 and cover 130.

[0022] Furthermore, as shown in Figure 5, the housing 110 is configured as a cylindrical shape having a substantially L-shaped outer form in side view, with a first opening 113 into which an electrical cable 300 is inserted on one end and a second opening 114 on the other end that exposes a terminal portion 410 connected to the end of the electrical cable 300 inserted through the first opening 113. In this embodiment, the first opening 113 is provided in a planar shape so as to be able to form a plane along the first opening 113, and the second opening 114 is also provided in a planar shape so as to be able to form a plane along the second opening 114.

[0023] Here, as shown in Figure 5, in this embodiment, in a cross-section of the housing 110 in a side view along the electrical cable 300 passing through the first opening 113 (see also Figure 4), the first line P1 along the first opening 113 is inclined with respect to the second line P2 along the second opening 114 and the third line P3 which extends in a direction perpendicular to the second line P2 through the intersection of the first line P1 and the second line P2. As a result, in this embodiment, the electrical cable 300 can pass through the housing 110 in a nearly straight line through both the first opening 113 and the second opening 114.

[0024] More specifically, the first line P1 is inclined linearly such that it moves away from the second line P2 along the Z direction, which is the first direction perpendicular to the second line P2, and moves away from the third line P3 along the X direction, which is the second direction parallel to the second line P2 (i.e., it moves closer to the end of the electrical cable 300 housed in the housing 110). Also, the first opening 113 and the second opening 114 are provided so that they do not overlap with each other in line of sight in the Z direction, which is the first direction.

[0025] In addition, in the embodiment, the housing 110 is made of a conductive material such as metal or metal-plated resin and is electrically connected to ground (or earth) as a reference potential point.

[0026] As shown in Figure 6, the housing 110 includes a cable support portion 111 which supports the exposed braid 320 of the electrical cable 300 and is electrically connected to ground, with at least an inner surface being conductive. The cable support portion 111 includes a substantially arc-shaped portion 111A in cross-section which supports a portion of the outer circumference of the exposed braid 320 of the electrical cable 300 from below on its inner surface, and the braid 320 supported on the inner surface of the cable support portion 111 is fixed to the housing 110 by an elastic conductive member 160.

[0027] The elastic conductive member 160 is made of a plate-shaped member (for example, a plate-shaped metal member) that is elastic and conductive. The elastic conductive member 160 is configured to hold the braid 320 to the housing 110 by elastically deforming in response to contact with the braid 320, and to electrically connect the braid 320 to the cable support portion 111 (and thus to the ground) by contacting the inner surface of the cable support portion 111.

[0028] In this embodiment, the elastic conductive member 160 is constructed by bending a plate-shaped metal member into a symmetrical M-shape, where two inverted U-shaped portions of approximately the same size, open toward the cable support portion 111, are connected in the Y direction (see also Figure 3). More specifically, the elastic conductive member 160 includes a plate portion 161, a plate portion 162 facing the plate portion 161, a plate portion 163 facing the plate portion 162, a plate portion 164 facing the plate portion 163, a bent portion 165 connecting the plate portion 161 and the plate portion 162, a bent portion 166 connecting the plate portion 162 and the plate portion 163, a bent portion 167 connecting the plate portion 163 and the plate portion 164, a claw portion 168 provided at the end of the plate portion 161 opposite to the bent portion 165, and a claw portion 169 provided at the end of the plate portion 164 opposite to the bent portion 167. In one embodiment, for example, an inverted U-shaped portion composed of a plate portion 161, a plate portion 162, and a bent portion 165 constitutes a cable housing portion for housing the braided electrical cable 300 320.

[0029] In this embodiment, the distance between plate portion 161 and plate portion 162 is smaller than the diameter of the braid 320. As a result, the braid 320 is held in place by being elastically sandwiched between plate portion 161 and plate portion 162.

[0030] Furthermore, in this embodiment, the cable support portion 111 includes a wall portion 112 that separates each of the braids 320 of the two electrical cables 300 and is electrically connected to the ground. As a result, the plate portion 164 of the elastic conductive member 160 is biased against the wall portion 112 of the housing 110 in accordance with the elastic deformation that occurs when the braid 320 is sandwiched between plate portions 161 and 162.

[0031] Furthermore, in this embodiment, when the braid 320 is sandwiched between the plate portion 161 and the plate portion 162 as described above, the claw portion 169 provided at the end of the plate portion 164 opposite to the bent portion 167 is locked to the wall portion 112 of the housing 110. This fixes the elastic conductive member 160 to the housing 110, and as a result, the holding of the electrical cable 300 and its connection to the ground are maintained.

[0032] Furthermore, as shown in Figures 3 and 4, in this embodiment, a cover 130 is attached to the rear side of the housing 110. The cover 130 is connected to the housing 110 by screws 500, with a sealing member 140 in between, so as to cover the first opening 113 of the housing 110 (see Figure 5). The screws 500 pass through through holes 131 and 141 (see Figure 3) provided in the cover 130 and the sealing member 140, respectively, and are screwed into the inner circumferential surface of screw holes (see Figure 6) provided in the housing 110.

[0033] Here, as shown in Figure 3, in this embodiment, the sealing member 140 sandwiched between the housing 110 and the cover 130 is configured in a substantially rectangular frame shape along the edge of the first opening 113 (see Figure 5). The sealing member 140 is made of, for example, rubber. The sealing member 140 also has a first rib 142 as a substantially rectangular frame-shaped wall rising from the surface of the sealing member 140 so as to face the edge of the first opening, and a second rib 143 as a cylindrical wall provided around the through hole 141. Note that the first rib 142 may be provided not only on the surface of the sealing member 140 on the housing 110 side, but also on the back surface on the cover 130 side.

[0034] In this embodiment, the cover 130 has a cylindrical portion 132 on its rear side through which an electrical cable 300 extending from inside the housing 110 passes. A cylindrical cap member 150 is attached to the cylindrical portion 132 via an annular gasket 151 and a clamp 152. As a result, the electrical cable 300 that passes through the cylindrical portion 132 and is exposed to the outside of the cover 130 is secured by the gasket 151, the clamp 152, and the cap member 150.

[0035] The manufacturing process of the plug connector 100 according to the embodiment will be described below, mainly with reference to Figures 7 and 8.

[0036] Figure 7 is a partial cross-sectional view showing the state in which the electrical cable 300 passes linearly through the housing 110 during the manufacturing process of the plug connector 100 according to the embodiment, and Figure 8 is a perspective view illustrating the attachment of the elastic conductive member 160 during the manufacturing process of the plug connector 100 according to the embodiment.

[0037] In this embodiment, during the manufacturing of the plug connector 100, an electrical cable 300 is first passed through the cap member 150, gasket 151, clamp 152, cover 130, and sealing member 140. Then, the electrical cable 300 is inserted into the first opening 113 and the second opening 114 of the housing 110. In this embodiment, as shown in Figure 7, the terminal portion 410 is connected to the internal wiring 310 at the end of the electrical cable 300 that has passed through the housing 110 and is exposed from the second opening 114. Note that in Figure 7, the sealing member 140 is omitted from the illustration for simplicity.

[0038] As already mentioned above, in this embodiment, the first opening 113 and the second opening 114 are positioned in such a way that the electrical cable 300 can pass straight through the housing 110. Therefore, in this embodiment, the steps of inserting the electrical cable 300 into the housing 110 when attaching the terminal portion 410 to the end of the electrical cable 300, and pulling the electrical cable 300 back to house the entire terminal portion 410 attached to the end of the electrical cable 300 inside the housing 110, can be easily performed while suppressing friction between the outer surface of the electrical cable 300 and the inner surfaces of the first opening 113 and the second opening 114.

[0039] In this embodiment, once the electrical cable 300 is pulled back, the entire terminal portion 410 is housed within the housing 110. As a result, in this embodiment, as shown in Figure 8, the braided portion 320 of the electrical cable 300 is exposed outside the housing 110. In this embodiment, the elastic conductive member 160 is attached to hold the braided portion 320 against the cable support portion 111 and to connect to the ground via the wall portion 112 of the cable support portion 111. The elastic deformation associated with the attachment of the elastic conductive member 160 has already been explained with reference to Figure 6, so it will not be explained here.

[0040] In this embodiment, once the installation of the elastic conductive member 160 is complete, the sealing member 140 and cover 130, through which the electrical cable 300 has been pre-passed, are joined to the housing 110 by screws 500. Subsequently, the cover 130 and the cap member 150 are joined via a gasket 151 and a clamp 152. In this way, the plug connector 100 according to this embodiment is manufactured.

[0041] As described above, the plug connector 100 according to the embodiment comprises a housing 110 and a cover 130. The housing 110 is configured to house a terminal portion 410 connected to the end of an electrical cable 300. The housing 110 is cylindrical in shape, with a first opening 113 into which the electrical cable 300 is inserted on one end, and a second opening 114 on the other end that exposes the terminal portion 410 connected to the end of the electrical cable 300 inserted through the first opening 113. The cover 130 is coupled to the housing 110 so as to cover the first opening 113 of the housing 110. The coupled housing 110 and cover 130 form a substantially L-shaped internal space in a side view. In a cross-section of the housing 110 in a side view along the electrical cable 300 passing through the first opening 113, the first line P1 along the first opening 113 is inclined such that as it moves away from the second line P2 in a first direction (Z direction) perpendicular to the second line P2 along the second opening 114, it approaches the end of the electrical cable 300 in a second direction (X direction) parallel to the second line P2.

[0042] With the above configuration, when inserting and removing the electrical cable 300 into and out of the housing 110 during the manufacturing of the plug connector 100, it becomes easier to pass the electrical cable 300 through both the first opening 113 and the second opening 114 in a nearly straight line within the housing 110. Therefore, compared to conventional configurations where it is necessary to bend the electrical cable 300 within the housing 110 while inserting and removing the electrical cable 300 into and out of the housing 110, work efficiency can be improved.

[0043] Furthermore, in this embodiment, the first opening 113 and the second opening 114 are arranged so as not to overlap in the line of sight in the Z direction.

[0044] With the above configuration, it is possible to prevent foreign matter that enters the plug connector 100 as a finished product through the first opening 113 from reaching the receptacle connector 200 side through the second opening 114.

[0045] In this embodiment, the first opening 113 and the second opening 114 are provided in a planar shape.

[0046] With the above configuration, the easy-to-install planar first opening 113 and second opening 114 improve the ease of inserting and removing the electrical cable 300 from the housing 110.

[0047] Furthermore, the plug connector 100 according to this embodiment further includes a frame-shaped sealing member 140 that is sandwiched between the housing 110 and the cover 130.

[0048] With the above configuration, the sealing member 140 can seal the inside of the housing 110 and cover 130.

[0049] In another embodiment, the sealing member 140 has a first rib 142 that rises from the surface of the sealing member 140 so as to face the edge of the first opening 113.

[0050] With the above configuration, the first rib 142 can increase the strength of the sealing member 140 and also improve the waterproof or dustproof performance of the sealing member 140.

[0051] In this embodiment, the housing 110 and the cover 130 are joined by screws 500 with a sealing member 140 in between.

[0052] With the above configuration, the housing 110 and the cover 130 can be firmly joined together by screws 500.

[0053] In addition, in this embodiment, the sealing member 140 further has a second rib 143 provided around the through hole 141 through which a screw 500 provided in the sealing member 140 passes.

[0054] With the above configuration, the second rib 143 further increases the strength of the sealing member 140 and further enhances the waterproof or dustproof performance of the sealing member 140.

[0055] <Variation> In the embodiments described above, a configuration in which two electrical cables 300 are provided is illustrated. However, the technology of this disclosure is also applicable to configurations in which only one electrical cable 300 is provided, as well as configurations in which three or more electrical cables 300 are provided.

[0056] Furthermore, in the embodiments described above, an example is provided of an elastic conductive member 160 having a Y-symmetrical M-shape, which is formed by connecting two inverted U-shaped sections of approximately the same size in the Y direction. However, as a modification, a configuration using an elastic conductive member with a Y-asymmetrical shape, such as a horizontal S-shape or one free end having multiple folds, is also conceivable. Other examples of Y-asymmetrical shapes include an M-shape, which is formed by connecting two inverted U-shaped sections of different sizes or shapes in the Y direction. When holding two electrical cables with Y-asymmetrical elastic conductive members such as these modifications, it is necessary to use the two elastic conductive members with their orientations in the Y direction reversed.

[0057] Here, with reference to Figure 9, an example of an M-shaped elastic conductive member with an asymmetrical shape in the Y direction will be described more specifically as a modified example. Figure 9 is a cross-sectional view showing the elastic conductive member 1160 according to the modified example.

[0058] In the modified example shown in Figure 9, the elastic conductive member 1160 has an asymmetrical M-shape in the Y direction, which is formed by connecting two inverted U-shaped portions of different shapes in the Y direction. More specifically, the elastic conductive member 1160 is made of a plate-shaped metal member that is bent to have a plate portion 1161, a plate portion 1162 facing the plate portion 1161, a plate portion 1163 facing the plate portion 1162, a plate portion 1164 facing the plate portion 1163, a bent portion 1165 connecting the plate portion 1161 and the plate portion 1162, a bent portion 1166 connecting the plate portion 1162 and the plate portion 1163, a bent portion 1167 connecting the plate portion 1163 and the plate portion 1164, a claw portion 1168 provided at the end of the plate portion 1161 opposite to the bent portion 1165, and a claw portion 1169 provided at the end of the plate portion 1164 opposite to the bent portion 1167. The plate portion 1162 includes a plate portion 1162A connected to the bent portion 165 so as to be substantially opposite to the plate portion 1161, and a plate portion 1162B extending linearly from the end of the plate portion 1162A opposite to the bent portion 165 toward the bent portion 1166 toward the bent portion 1161, away from the plate portion 1161.

[0059] In the modified example shown in Figure 9, one inverted U-shaped portion, composed of plate portion 1161, plate portion 1162, and bent portion 165, constitutes a cable housing portion that accommodates the electrical cable 300 (and presses against the cable support portion 111), while the other inverted U-shaped portion, composed of plate portion 1163, plate portion 1164, and bent portion 1167 (particularly plate portion 1164), constitutes a biased portion that is biased against the wall portion 112 of the housing 110 (see Figure 6). The roles of the claw portions 1168 and 1169 are the same as those of the claw portions 168 and 160 of the elastic conductive member 160 in the embodiment described above.

[0060] Furthermore, in the above-described embodiment, a configuration is exemplified in which the first opening 113 into which the electrical cable 300 is inserted is provided in a planar shape. However, as a modification, a configuration in which the first opening is provided in a curved shape is also conceivable. As such a modification, for example, a configuration in which only a part of the upper surface of the housing is cut out is conceivable. In this configuration, the cover-side end of the upper surface of the housing does not extend in a straight line in the Y direction, but is partially cut out on the front side of the housing in the part that interferes with the electrical cable when inserting or removing the electrical cable. Even with such a configuration, when viewed in a cross-section in a side view along the electrical cable passing through the first opening, it is possible for the electrical cable to pass through the housing in a substantially straight line through both the first and second openings, similar to the above-described embodiment.

[0061] While embodiments and variations of the present invention have been described above, these embodiments and variations are presented as examples only and are not intended to limit the scope of the invention. These novel embodiments and variations can be implemented in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and variations are included in the scope and spirit of the invention, as well as in the claims of the invention and its equivalents. [Explanation of symbols]
