Background Art
[0002] An electrical connector has been used for a long time. The electrical connector includes a contact and a housing for holding the contact, and the housing is provided with a through hole for a mounting component for mounting the housing on other components to pass through. In such an electrical connector, a bushing is provided, which passes through the through hole of the housing in a clearance fit state, and a through hole for the mounting component to be inserted is formed in the bushing. Furthermore, by mounting the mounting component on other components in a state where the bushing is inserted, the bushing is fixed to the other components, and the housing through which the bushing is penetrated in a clearance fit state is mounted relative to other components via the bushing in a state capable of relative displacement. As such an electrical connector, for example, the electrical connector disclosed in Patent Document 1 is known.
[0003] Patent document 1 discloses a plug-type connector 110, which is an electrical connector including a plug-side contact 130 and a plug housing 120 for holding the plug-side contact 130. The plug housing 120 of the plug-type connector 110 is provided with a grommet mounting hole 129, which is a through hole through which a bolt 155 passes, and the bolt 155 is a mounting component for mounting the plug housing 120 to a counterpart side component 6, which is another component. In addition, the plug-type connector 110 is provided with a grommet component 150 as a bushing, which passes through the grommet mounting hole 129 of the plug housing 120 in a clearance fit state, and is formed with a bolt insertion hole 153, which is a through hole through which the bolt 150, which is a mounting component, is inserted. Moreover, the bolt 150 is installed on the object side component 6 as another component in a state where it is inserted into the eyelet component 150 serving as a bushing, so that the eyelet component 150 is fixed to the object side component 6, and the plug housing 120 penetrated by the eyelet component 150 in a clearance fit state is installed on the object side component 6 via the eyelet component 150 in a state where it can be relatively displaced relative to the object side component 6.
[0004] In the plug connector 110 of Patent Document 1, an eyelet component 150 as a bushing is provided in order to mount the plug housing 120 on the counterpart side component 6 as another component in a clearance fit state. The eyelet component 150 is composed of a disc-shaped upper eyelet component 151 and a disc-shaped lower eyelet component 152 having a shaft portion 152a extending upward from the center portion thereof. The shaft portion 152a is formed to have a diameter smaller than the diameter of the eyelet insertion hole 129 which is a through hole provided in the plug connector 120, thereby the eyelet component 150 is provided in a clearance fit state with respect to the plug connector. The eyelet component 150 is mounted on the plug housing 120 by inserting the shaft portion 152a of the lower eyelet component 152 into the eyelet insertion hole 129 of the plug housing 120 from below and mounting and fixing the upper eyelet component 151 to the upper end portion of the shaft portion 152a.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2010-80111 Summary of the invention
[0008] Problems to be solved by the invention
[0009] In the structure disclosed in Patent Document 1, the eyelet component 150 is a bushing that penetrates the eyelet insertion hole 129 that is a through hole of the plug housing 120 in a clearance fit state, and the eyelet component 150 is composed of a disc-shaped upper eyelet component 151 and a disc-shaped lower eyelet component 152 that has a shaft portion 152a extending upward from its center portion. After the plug housing 120 is formed, the shaft portion 152a of the lower eyelet component 152 is inserted into the eyelet insertion hole 129 of the plug housing 120, and the upper eyelet component 151 is attached to the upper end of the shaft portion 152a, thereby assembling the eyelet component 150 to the plug housing 120. Therefore, in the structure disclosed in Patent Document 1, after the plug housing 120 that is a housing is formed, the eyelet component 150 that is a bushing needs to be assembled to the plug housing 120. Therefore, after the molding process of the plug housing 120, it is necessary to perform a process of assembling the eyelet member 150 to the plug housing 120, which increases the number of assembly steps and leads to an increase in manufacturing costs. In addition, as the number of assembly steps increases, assembly equipment may be required to perform the increased number of assembly steps, which further increases manufacturing costs.
[0010] In view of the above-mentioned actual situation, the object of the present invention is to provide an electrical connector, which comprises contacts and a shell for holding the contacts, and the shell is provided with a through hole for a mounting component for mounting the shell on other components to pass through, and the shell is mounted on the other components via a bushing. In this electrical connector, the increase in assembly man-hours can be suppressed, thereby suppressing the increase in manufacturing costs.
[0011] Means for solving problems
[0012] (1) An electrical connector according to one aspect of the present invention for achieving the above-mentioned object comprises a plurality of contacts formed of a metal material and a housing formed of a resin material and holding the plurality of contacts, wherein the housing is provided with a through hole through which a mounting component for mounting the housing on another component passes. Furthermore, an electrical connector involved in one aspect of the invention is characterized in that the electrical connector also includes a bushing, which passes through the through hole and is provided with a through hole for inserting the mounting component, the bushing includes: a shaft portion, which passes through the through hole in a clearance fit state; and a first flange portion and a second flange portion, which are respectively arranged at two end portions in the axial direction of the shaft portion, and the through hole that passes through the shaft portion along the axial direction is provided on the shaft portion, the first flange portion and the second flange portion are integrally arranged on the shaft portion at two end portions in the axial direction of the shaft portion, at least the first flange portion and the second flange portion in the bushing are formed of a resin material, the first flange portion and the second flange portion are arranged to protrude from the shaft portion in a radial direction, the radial direction is a direction perpendicular to the axial direction, and the first flange portion and the second flange portion are arranged to protrude from the shaft portion in the radial direction at positions that do not overlap when viewed from the axial direction.
[0013] According to this structure, the shaft portion of the bushing passes through the through hole of the housing in a clearance fit state, the first flange portion and the second flange portion integrally provided with the shaft portion are arranged on both sides of the through hole, and the bushing is provided in the housing in a clearance fit state. Furthermore, when the electrical connector is mounted on other components, the mounting component is mounted to the other components in a state of being inserted into the through hole of the bushing, so that the bushing is fixed to the other components, and the housing penetrated by the bushing in a clearance fit state is mounted to the other components via the bushing in a state of being relatively displaceable relative to the other components.
[0014] In addition, according to the above structure, the first flange portion and the second flange portion of the bushing are integrally provided with the shaft portion at both ends of the shaft portion in the axial direction that penetrates the through hole of the housing in a clearance fit state, and are formed of a resin material. In addition, the first flange portion and the second flange portion are provided to protrude from the shaft portion along the radial direction of the shaft portion, and the first flange portion and the second flange portion are provided to protrude from the shaft portion in the radial direction at positions that do not overlap when viewed from the axial direction. Therefore, the housing and the bushing that penetrates the housing in a clearance fit state and is integrally provided with the first flange portion and the second flange portion at both ends of the shaft portion can be formed by integral molding using resin injection molding. In addition, as a mold for integral molding of the housing and the bushing, a mold composed of a fixed core and a movable core combined in the height direction, and a side core combined in a direction perpendicular to the height direction can be used to integrally mold the housing and the bushing. The overall shape of the housing is formed by integral molding in an area divided by a fixed core and a movable core, and a side core, wherein the fixed core and the movable core are combined in a height direction, and the side core is combined in a direction perpendicular to the height direction. The first flange portion and the second flange portion of the bushing are formed by integral molding in an area divided by the side core, and the shaft portion of the bushing is provided integrally with the first flange portion and the second flange portion in the area divided by the fixed core and the movable core. The first flange portion and the second flange portion are formed in a shape protruding radially from the shaft portion at a position where they do not overlap when viewed from the axial direction. Therefore, the first flange portion and the second flange portion protruding radially from the shaft portion can be formed by the side core, and the shaft portion integrally formed with the first flange portion and the second flange portion can be provided by the fixed core and the movable core. The portion of the area dividing the shaft portion of the bushing in the fixed core and the movable core extends in the axial direction, and in the axial direction, the portion overlaps only one of the first flange portion and the second flange portion. Therefore, it is possible to integrally mold: a shaft portion, a first flange portion and a second flange portion integrally provided with the shaft portion at both ends of the shaft portion in the axial direction, and a housing provided with a through hole for the shaft portion to pass through. In this way, according to the above structure, a mold having a fixed core and a movable core combined in the height direction, and a side core combined in a direction perpendicular to the height direction can be used to form a housing and a bushing by integral molding using resin injection molding, wherein the bushing passes through the housing in a clearance fit state and is integrally provided with a first flange portion and a second flange portion at both ends of the shaft portion. Therefore, it is not necessary to perform a process of assembling the bushing to the molded housing after the molding process of the housing as in the past, and the housing and the bushing can be integrally molded, which can suppress the increase in assembly man-hours and thus suppress the increase in manufacturing costs. In addition, there is no need for assembly equipment for implementing the assembly process, which can also suppress further increases in manufacturing costs.
[0015] As described above, according to the above structure, an electrical connector can be provided, which includes contacts and a shell for holding the contacts, and the shell is provided with a through hole for a mounting component for mounting the shell on other components to pass through, and the shell is mounted on the other components via a bushing. In this electrical connector, the increase in assembly man-hours can be suppressed, thereby suppressing the increase in manufacturing costs.
[0016] (2) The first flange portion, the second flange portion, and the shaft portion of the bush may be formed of a resin material.
[0017] When the shaft portion of the bushing is made of a metal material other than a resin material, the housing and the bushing can be integrally molded by injecting resin into the mold while the shaft portion of the bushing is arranged in the mold. However, when the shaft portion of the bushing is also made of a resin material, the housing and the bushing can be integrally molded by resin injection molding without arranging the shaft portion of the bushing in the mold.
[0018] (3) The first flange portion and the second flange portion may be provided so as to expand in a fan shape from the shaft portion toward the outer side in the radial direction.
[0019] According to this structure, since the first flange portion and the second flange portion are arranged to expand in a fan-shaped manner from the shaft portion, the first flange portion and the second flange portion can be extended and arranged with good spatial efficiency in the radial direction within a range where the first flange portion and the second flange portion do not overlap in the axial direction. Therefore, the areas of the first flange portion and the second flange portion can be further increased.
[0020] (4) The first flange portion may be provided in pair, and the pair of the first flange portions may be provided so as to protrude from the shaft portion toward opposite sides in the radial direction.
[0021] According to this structure, a pair of first flanges are provided and protrude in opposite directions in the radial direction, so the first flanges can be radially extended and arranged at dispersed positions around the shaft. Therefore, the area of the first flanges can be further expanded in a dispersed state around the shaft.
[0022] (5) The second flange portion may be provided in pair, and the pair of second flange portions may be provided so as to protrude from the shaft portion toward opposite sides in the radial direction.
[0023] According to this structure, a pair of second flanges are provided and protrude in opposite directions in the radial direction, so the second flanges can be radially extended and arranged at dispersed positions around the shaft. Therefore, the area of the second flanges can be further expanded in a dispersed state around the shaft.
[0024] (6) It may also be that the first flange portion is configured as follows: when the shell is installed on the other component, the first flange portion is opposite to the other component, and an abutment portion is provided on the shell. The abutment portion is configured to protrude in a direction parallel to the axial direction by a protrusion amount higher than the height dimension of the first flange portion and abut against the other component.
[0025] The first flange and the second flange are formed by the side core together with the housing, so a gap is provided between the housing and the first flange, and between the housing and the second flange to form a certain degree of gap. In addition, by fixing the mounting component in the state of the through hole inserted in the bushing (through the through hole of the housing in a clearance fit state) to other components, the housing is installed on other components via the bushing in a state that can be relatively displaced relative to other components. At this time, if the gap between the housing and the first flange and the second flange is large, the part of the housing installed on other components via the bushing in a relatively displaceable manner is displaced greatly in a manner inclined relative to the shaft of the bushing, and it is possible to cause damage. However, the housing is provided with an abutment portion, which protrudes axially relative to the first flange portion opposite to other components and abuts against other components. In addition, by the abutment of the abutment portion of the housing with other components, the movement amount of the housing to the first flange side is limited, and the gap between the housing and the second flange is also reduced. Therefore, the housing, which is relatively displaceably mounted to other components via the bushing, can be prevented from being displaced in a manner inclined relative to the shaft of the bushing. Thus, damage itself caused by the enlargement of the gap between the housing and the first flange and the second flange can be prevented.

[0027] According to the present invention, an electrical connector is provided, which includes contacts and a shell for holding the contacts, and the shell is provided with a through hole for a mounting component for mounting the shell on other components to pass through, and the shell is mounted on the other components via a bushing. In this electrical connector, the increase in assembly man-hours can be suppressed, thereby suppressing the increase in manufacturing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The following describes a method for implementing the present invention with reference to the accompanying drawings. In addition, the present invention can be widely used in various applications as an electrical connector, which includes a contact and a housing for holding the contact, a through hole for a mounting component for mounting the housing relative to other components to penetrate the housing, and the housing is mounted to the other components via a bushing.
[0057] [Schematic structure of electrical connector]
[0058] Figure 1 This is a front view showing the electric connector 1 according to one embodiment of the present invention together with a connector mounting plate 100 as another component on which the electric connector 1 is mounted. Figure 2 This is a perspective view showing the electric connector 1 together with a connector mounting plate 100 as another component to which the electric connector 1 is mounted. Figure 31 is a diagram showing the electric connector 1 together with a connector installation plate 100 as another component on which the electric connector 1 is mounted. Figure 3 In the figure, (A) is a side view, and (B) is a bottom view. Figure 4 It is a perspective view showing the housing 12 and the bushing 13 of the electric connector 1 .
[0059] Figures 1 to 4 The electrical connector 1 shown in the figure is configured to include: a plurality of contacts 11 formed of a metal material; a housing 12 formed of a resin material and holding the plurality of contacts 11; and a bushing 13 provided in the housing 12 in a clearance fit state. The contacts 11 are held in the housing 12 in a state connected to the electric wires 102. Figures 1 to 3 In FIG. 1 , the portion of the end portion connected to the contact 11 is schematically shown in a missing state for the electric wire 102 connected to the contact 11. Figures 1 to 3 In FIG. 1 , a connector setting plate 100 , which is another component on which the electric connector 1 is mounted, is schematically shown in a missing state and only a portion thereof, and the portion on which the electric connector 1 is mounted and the vicinity thereof are illustrated.
[0060] The housing 12 of the electric connector 1 is provided with a through hole 26 through which a bolt 101 passes. The bolt 101 is a mounting component for mounting the housing 12 on the connector setting plate 100 as another component. The bushing 13 is provided in the housing 12 in a clearance fit state while penetrating the through hole 26 of the housing 12. That is, the bushing 13 is provided in the housing 12 in a state in which it can be relatively displaced with respect to the housing 12 within the range of the area where the displacement is restricted by the through hole 26 of the housing 12. In addition, the bushing 13 penetrating the through hole 26 of the housing 12 is provided with a through hole 33 through which the bolt 101 is inserted. The bolt 101 penetrates the through hole 26 of the housing 12 while being inserted in the through hole 33 of the bushing 13. When the electric connector 1 is mounted on the connector setting plate 100, the bolt 101 penetrates the through hole 33 of the bushing 13 penetrating the through hole 26 of the housing 12. The bolt 101 further penetrates the through hole for installation (not shown) provided in the connector setting plate 100, and is screwed with the nut 103, so that the bushing 13 is fixedly installed on the connector setting plate 100. Thus, the housing 12 is installed on the connector setting plate 100 via the bushing 13. The bushing 13 penetrates the through hole 26 of the housing 12 in a clearance fit state, and the bushing 13 is fixedly installed on the connector setting plate 100. Thus, the housing 12 is installed on the connector setting plate 100 via the bushing 13 in a state that it can be displaced relative to the connector setting plate 100. The electric connector 1 is installed on the connector setting plate 100 in a state where the electric wire 102 is connected to the contact 11. Moreover, the electric connector 1 installed on the connector setting plate 100 is mated and connected to the counterpart electric connector (not shown).
[0061] The connector setting plate 100, which is another component for mounting the electric connector 1, is provided as a flat plate-shaped component constituting a part of the base for mounting the electric connector 1, for example. In the present embodiment, a flat plate-shaped connector setting plate 100 is exemplified as another component for mounting the electric connector 1, but this may not be the case. For example, another component for mounting the electric connector 1 may be various components such as a component constituting a frame, a frame-shaped component, or a panel-shaped component. In addition, in the present embodiment, a mounting component is inserted into the insertion hole 33 of the bushing 13 that penetrates the through hole 26 of the housing 12 and is used to mount the housing 12 to another component, and a bolt 101 is exemplified as the mounting component, but this may not be the case. The mounting component may be any component that can be inserted into the insertion hole 33 of the bushing 13 that penetrates the through hole 26 of the housing 12 and mount the housing 12 to another component, and may be, for example, an external thread component, a rivet, etc. When the mounting component is an external thread component, the external thread component is inserted into the through hole 33 while the screw head of the external thread component abuts against the edge of the through hole 33 of the bushing 13, and the end side of the external thread component is threadedly engaged with other components, thereby mounting the housing 12 on the other components via the bushing 13.
[0062] The following describes a more detailed structure of the electrical connector 1. Figures 1 to 4 As shown by the double-headed arrows X1, X2, and X3 in the drawings described later, the height direction X1, width direction X2, and front-back direction X3 of the electric connector 1 are defined. The height direction X1 is a direction in which the electric connector 1 is mounted on the connector setting plate 100 as another component. In addition, the height direction X1 is an extension direction of the through hole 26 of the housing 12, and is also an extension direction of the through hole 33 of the bushing 13 that penetrates the through hole 26. In addition, the height direction X1 is a direction in which the bolt 101 as a mounting component penetrates the through hole 26 of the housing 12, and is also a direction in which the bolt 101 is inserted into the through hole 33 of the bushing 13. The width direction X2 is a direction perpendicular to the height direction X1, and is a direction in which the plurality of contacts 11 are arranged in the electric connector 1. In addition, in the present embodiment, in the electric connector 1, the plurality of contacts 11 are arranged in two rows along the width direction X2. The front-back direction X3 is a direction perpendicular to both the height direction X1 and the width direction X2.
[0063] [Contact]
[0064] Figure 5 FIG. 1 is a perspective view showing one of the contacts 11 in the electrical connector 1 in an enlarged manner. Figure 1 , Figure 3 as well as Figure 5The electrical connector 1 is provided with a plurality of contacts 11. The plurality of contacts 11 are each formed of a conductive metal material, configured to be crimped and connected to the electric wire 102, and are inserted into the housing 12 and held in the housing 12.
[0065] The contact 11 is connected to the end of the electric wire 102 by crimping, and is inserted into the housing 12 along the height direction X1 and held in the housing 12. The housing 12 is provided with a plurality of contact holding holes 25 (see FIG. 2 ) into which the plurality of contacts 11 are respectively inserted. Figure 4 ). Each contact holding hole 25 is arranged to pass through the housing 12 in the height direction X1, and a plurality of contact holding holes 25 are arranged in two rows along the width direction X2 in the housing 12. By inserting and holding each contact 11 in each contact holding hole 25, a plurality of contacts 11 are arranged in two rows along the width direction X2 in the housing 12. In addition, each contact holding hole 25 passes through the housing 12 in the height direction X1, and each contact 11 connected to each electric wire 102 is inserted into the contact holding hole 25 from one side in the height direction X1 and is held in the contact holding hole 25. When the electric connector 1 is mated and connected with the counterpart electric connector (not shown), the counterpart contact of the counterpart electric connector is inserted into the contact holding hole 25 from the opening on the other side of the contact holding hole 25 of the housing 12 in the height direction X1, and contacts the contact 11. As a result, the contact 11 of the electric connector 1 is electrically connected with the counterpart contact of the counterpart electric connector.
[0066] like Figure 5 As shown, the contact 11 has a length direction extending in the height direction X1 when inserted into the housing 12. A contact connecting portion 21 is provided on one end side of the length direction of the contact 11, and a wire connecting portion 22 is provided on the other end side of the length direction of the contact 11. The contact connecting portion 21 is provided as a portion on the end side of the terminal end when the contact 11 is inserted into the housing 12, and is provided as a portion for electrical connection by contact with a counterpart side contact (omitted from the illustration) of a counterpart side electrical connector (omitted from the illustration) connected to the electrical connector 1. The wire connecting portion 22 is provided as a portion that is crimped and connected to the end of the wire 102 by pressing. In addition, in Figure 5, the contact 11 is shown in a state before being crimped to the end of the electric wire 102. The electric wire connecting portion 22 is provided with a core wire crimping portion 22a and a sheath crimping portion 22b, the core wire crimping portion 22a is crimped to the core wire of the electric wire 102 (not shown in the figure) by pressing, and the sheath crimping portion 22b is crimped to the sheath of the electric wire 102 (not shown in the figure) by pressing. The electric wire 102 has a core wire as a conductor and a sheath made of an insulating material surrounding the core wire. At the end of the electric wire 102 crimped to the contact 11, the sheath at the terminal end is partially removed to expose the core wire. When the electric wire connecting portion 22 is crimped and connected to the end of the electric wire 102, the core wire crimping portion 22a is crimped to the core wire at the end of the electric wire 102, and the sheath crimping portion 22b is crimped to the sheath at the end of the electric wire 102.

In addition, the nut 103 screwed with the tip of the bolt 101 that passes through the bushing 13 and the connector installation plate 100 abuts against the end surface of the connector installation plate 100 on the opposite side to the side facing the bushing 13. As a result, the bushing 13 and the connector installation plate 100 are fixed to each other by the bolt 101 and the nut 103, and the housing 12 is installed on the connector installation plate 100 via the bushing 13. Furthermore, the bushing 13 passes through the through hole 26 of the housing 12 in a clearance fit state, and the bushing 13 is fixedly mounted on the connector mounting plate 100 , so that the housing 12 is mounted on the connector mounting plate 100 via the bushing 13 in a state that it can be displaced relative to the connector mounting plate 100 in the radial direction of the shaft portion 30 of the bushing 13 .

Furthermore, the shaft outer circumference forming portions 51a and 51b of the fixed core 51 and the shaft outer circumference forming portions 53a and 53b of the movable core 53 are configured so that, in a state where the fixed core 51 and the movable core 53 are combined in the height direction X1, the outer circumference of the shaft portion 30 of the bushing 13 is formed over the entire circumference, and the inner circumference of the through hole 26 of the housing 12 is formed over the entire circumference. By filling the divided regions with resin, the shaft portion 30 of the bushing 13 and the plate-like protrusion 24 a provided with the through hole 26 in the housing 12 are integrally molded so as to penetrate the through hole 26 with clearance fit inside the inner periphery of the through hole 26 .
[0101] The shaft inner periphery forming portion 53c of the movable core 53 is provided as a portion for forming the inner periphery of the shaft portion 30 of the bushing 13 provided in a clearance fit state on the plate-like protrusion 24a. The inner periphery of the shaft portion 30 defines a through hole 33 that penetrates the shaft portion 30 in the axial direction. Therefore, the shaft inner periphery forming portion 53c is provided as a portion for forming the through hole 33. The shaft inner periphery forming portion 53c is arranged between the shaft outer periphery forming portion 53a and the shaft outer periphery forming portion 53b, and is formed in a shape extending cylindrically along the height direction X1 corresponding to the axial direction of the shaft portion 30. When the fixed core 51 and the movable core 53 are combined in the height direction X1, the shaft outer circumference forming portion 51a and the shaft outer circumference forming portion 51b of the fixed core 51 and the shaft outer circumference forming portion 53a and the shaft outer circumference forming portion 53b of the movable core 53 are combined into a cylindrical shape, and the cylindrical shaft inner circumference forming portion 53c is arranged inside, thereby forming a cylindrical space. And, by filling the cylindrical space with resin, the outer circumference of the shaft 30 is formed by the shaft outer circumference forming portions 51a, 51b, 53a, 53b, and the inner circumference of the shaft 30 is formed by the shaft inner circumference forming portion 53c, thereby forming the shaft 30 provided with the through hole 33.
[0102] In addition, in a state where the fixed core 51 and the movable core 53 are combined in the height direction X1 and the side core 55 and the side core 57 are combined in the front-rear direction X3, the region divided by the shaft outer peripheral forming portions 51a, 51b, 53a, 53b and the shaft inner peripheral forming portion 53c communicates with the region divided by the first flange forming portion 55a of the side core 55, the first flange forming portion 57a of the side core 57, and the surface of the fixed core 51 that faces the first flange forming portions 55a, 57a. Furthermore, the region divided by the shaft outer peripheral forming portions 51a, 51b, 53a, 53b and the shaft inner peripheral forming portion 53c also communicates with the region divided by the second flange forming portion 55b of the side core 55, the second flange forming portion 57b of the side core 57, and the surface of the movable core 53 that faces the second flange forming portions 55b, 57b.

The shaft outer periphery forming portion 52a and the shaft outer periphery forming portion 52b define a region corresponding to a half circumference in the circumferential direction in the cylindrical space region between the outer periphery of the shaft portion 30 and the inner periphery of the through hole 26. In addition, the shaft outer periphery forming portion 52a and the shaft outer periphery forming portion 52b define a region corresponding to a quarter circumference in the circumferential direction in the cylindrical space region between the outer periphery of the shaft portion 30 and the inner periphery of the through hole 26. In addition, the shaft outer periphery forming portion 52a and the shaft outer periphery forming portion 52b are arranged to be arranged at a position offset from the first flange forming portion 56a of the side core 56 and the first flange forming portion 58a of the side core 58 in a state where the fixed core 52 and the movable core 54 are combined in the height direction X1 and the side core 56 and the side core 58 are combined in the front-rear direction X3. Thus, the outer periphery of a portion of the outer periphery of the shaft portion 30 that does not overlap with the first flange portion 31 in the axial direction is molded by the shaft portion outer periphery forming portion 52 a and the shaft portion outer periphery forming portion 52 b .
[0108] The shaft outer periphery forming portion 54a and the shaft outer periphery forming portion 54b of the movable core 54 are provided as portions for forming a portion in the circumferential direction of the outer periphery of the shaft portion 30 of the bushing 13 provided in the plate-like protrusion 24b in a clearance fit state and a portion in the circumferential direction of the inner periphery of the through hole 26 provided in the plate-like protrusion 24b. The shaft outer periphery forming portion 54a and the shaft outer periphery forming portion 54b are provided as portions for forming a cylindrical space region between the outer periphery of the shaft portion 30 of the bushing 13 provided in the through hole 26 of the housing 12 in a clearance fit state and the inner periphery of the through hole 26. The shaft outer periphery forming portion 54a and the shaft outer periphery forming portion 54b are respectively provided in a shape extending in the axial direction of the cylinder with an arc-shaped cross section, and the shaft outer periphery forming portion 54a and the shaft outer periphery forming portion 54b are arranged on the radially opposite sides of each other with the axis center of the shaft portion 30 formed inside them as the center. The shaft outer periphery forming portion 54a and the shaft outer periphery forming portion 54b define a region corresponding to a half circumference in the circumferential direction in the cylindrical space region between the outer periphery of the shaft portion 30 and the inner periphery of the through hole 26. In addition, the shaft outer periphery forming portion 54a and the shaft outer periphery forming portion 54b define a region corresponding to a quarter circumference in the circumferential direction in the cylindrical space region between the outer periphery of the shaft portion 30 and the inner periphery of the through hole 26. In addition, the shaft outer periphery forming portion 54a and the shaft outer periphery forming portion 54b are arranged to be arranged at a position offset from the second flange forming portion 56b of the side core 56 and the second flange forming portion 58b of the side core 58 in a state where the fixed core 52 and the movable core 54 are combined in the height direction X1 and the side core 56 and the side core 58 are combined in the front-rear direction X3. Thus, the outer periphery of a portion of the outer periphery of the shaft portion 30 that does not overlap with the second flange portion 32 in the axial direction is molded by the shaft portion outer periphery forming portion 54 a and the shaft portion outer periphery forming portion 54 b .
[0109] The shaft outer circumference forming portions 52a and 52b of the fixed core 52 and the shaft outer circumference forming portions 54a and 54b of the movable core 54 are combined into a cylindrical shape in a state where the fixed core 52 and the movable core 54 are combined in the height direction X1 to form a cylindrical region between the outer circumference of the shaft portion 30 of the bushing 13 and the inner circumference of the through hole 26 of the housing 12. Furthermore, the shaft outer circumference forming portions 52a and 52b of the fixed core 52 and the shaft outer circumference forming portions 54a and 54b of the movable core 54 are configured so that, in a state where the fixed core 52 and the movable core 54 are combined in the height direction X1, the outer circumference of the shaft portion 30 of the bushing 13 is formed over the entire circumference, and the inner circumference of the through hole 26 of the housing 12 is formed over the entire circumference. By filling the thus divided regions with resin, the shaft portion 30 of the bushing 13 which passes through the through hole 26 with clearance fit inside the inner periphery of the through hole 26 and the plate-like protrusion 24 b provided with the through hole 26 in the housing 12 are integrally molded.
[0110] The shaft inner circumference forming portion 54c of the movable core 54 is provided as a portion for forming the inner circumference of the shaft portion 30 of the bushing 13 provided in a clearance fit state on the plate-like protrusion 24b. The inner circumference of the shaft portion 30 defines a through hole 33 that penetrates the shaft portion 30 in the axial direction. Therefore, the shaft inner circumference forming portion 54c is provided as a portion for forming the through hole 33. The shaft inner circumference forming portion 54c is arranged between the shaft outer circumference forming portion 54a and the shaft outer circumference forming portion 54b, and is formed in a shape extending cylindrically along the height direction X1 corresponding to the axial direction of the shaft portion 30. When the fixed core 52 and the movable core 54 are combined in the height direction X1, the shaft outer circumference forming portion 52a and the shaft outer circumference forming portion 52b of the fixed core 52 and the shaft outer circumference forming portion 54a and the shaft outer circumference forming portion 54b of the movable core 54 are combined into a cylindrical shape, and the cylindrical shaft inner circumference forming portion 54c is arranged inside, thereby forming a cylindrical space. And, by filling the cylindrical space with resin, the outer circumference of the shaft 30 is formed by the shaft outer circumference forming portions 52a, 52b, 54a, 54b, and the inner circumference of the shaft 30 is formed by the shaft inner circumference forming portion 54c, thereby forming the shaft 30 provided with the through hole 33.
[0111] In addition, in a state where the fixed core 52 and the movable core 54 are combined in the height direction X1 and the side core 56 and the side core 58 are combined in the front-rear direction X3, the region divided by the shaft outer peripheral forming portions 52a, 52b, 54a, 54b and the shaft inner peripheral forming portion 54c communicates with the region divided by the first flange forming portion 56a of the side core 56, the first flange forming portion 58a of the side core 58, and the surface of the fixed core 52 that faces the first flange forming portions 56a, 58a. Furthermore, the region divided by the shaft outer peripheral forming portions 52a, 52b, 54a, 54b and the shaft inner peripheral forming portion 54c also communicates with the region divided by the second flange forming portion 56b of the side core 56, the second flange forming portion 58b of the side core 58, and the surface of the movable core 54 that faces the second flange forming portions 56b, 58b. Therefore, by filling the above-mentioned region with resin and curing it, the shaft portion 30 and the first flange portion 31 and the second flange portion 32 provided at both axial end portions of the shaft portion 30 are integrally molded and provided.
[0112] [Functions and Effects of the Present Embodiment]
[0113] According to the present embodiment, the shaft portion 30 of the bushing 13 passes through the through hole 26 of the housing 12 in a clearance fit state, the first flange portion 31 and the second flange portion 32 integrally provided with the shaft portion 30 are arranged on both sides of the through hole 26, and the bushing 13 is provided in the housing 12 in a clearance fit state. Furthermore, when the electric connector 1 is mounted on the connector setting plate 100 as another component, the bolt 101 as a mounting component is installed in the connector setting plate 100 in a state of being inserted in the through hole 33 of the bushing 13, so that the bushing 13 is fixed to the connector setting plate 100, and the housing 12 penetrated by the bushing 13 in a clearance fit state is installed in the connector setting plate 100 via the bushing 13 in a state of being displaceable relative to the connector setting plate 100.
[0114] Furthermore, according to the present embodiment, the first flange portion 31 and the second flange portion 32 of the bushing 13 are formed of a resin material and are provided integrally with the shaft portion 30 at both ends of the shaft portion 30 in the axial direction that passes through the through hole 26 of the housing 12 in a clearance fit state. Furthermore, the first flange portion 31 and the second flange portion 32 are provided so as to protrude from the shaft portion 30 in the radial direction of the shaft portion 30, and the first flange portion 31 and the second flange portion 32 are provided so as to protrude from the shaft portion 30 in the radial direction at positions that do not overlap when viewed from the axial direction. Therefore, the housing 12 and the bushing 13 that passes through the housing 12 in a clearance fit state and is provided integrally with the first flange portion 31 and the second flange portion 32 at both ends of the shaft portion 30 can be formed by integral molding using injection molding of a resin. In addition, as a mold for integrally molding the housing 12 and the bushing 13, a mold 50 can be used to integrally mold the housing 12 and the bushing 13. The mold 50 is configured to include: fixed cores 51, 52 and movable cores 53, 54 combined in the height direction X1; and side cores 55, 56 and side cores 57, 58 combined in the front-rear direction X3 perpendicular to the height direction X1. The overall shape of the housing 12 is integrally molded in the following area, which is divided by the fixed core and movable core combined in the height direction X1 and the side core combined in the front-rear direction X3 perpendicular to the height direction X1. The first flange portion 31 and the second flange portion 32 of the bushing 13 are integrally molded in the area divided by the side cores 55, 56 and the side cores 57, 58, and the shaft portion 30 of the bushing 13 is integrally molded in the area divided by the fixed cores 51, 52 and the movable cores 53, 54 and is formed integrally with the first flange portion 31 and the second flange portion 32. The first flange portion 31 and the second flange portion 32 are formed in a shape protruding in the radial direction from the shaft portion 30 at a position where they do not overlap when viewed from the axial direction. Therefore, the first flange portion 31 and the second flange portion 32 protruding in the radial direction from the shaft portion 30 can be formed by the side cores 55, 56 and the side cores 57, 58, and the shaft portion 30 integrally formed with the first flange portion 31 and the second flange portion 32 can be formed by the fixed cores 51, 52 and the movable cores 53, 54. The portion of the fixed cores 51, 52 and the movable cores 53, 54 that divides the region of the shaft portion 30 of the bushing 13 extends in the axial direction and overlaps only one of the first flange portion 31 and the second flange portion 32 in the axial direction. Therefore, the shaft portion 30, the first flange portion 31 and the second flange portion 32 integrally provided with the shaft portion 30 at both ends in the axial direction of the shaft portion 30, and the housing 12 provided with the through hole 26 through which the shaft portion 30 passes can be integrally formed.Thus, according to the present embodiment, the housing 12 and the bushing 13 can be formed by integral molding using resin injection molding using the mold 50, which includes the fixed cores 51, 52 and the movable cores 53, 54 combined in the height direction X1, and the side cores 55, 56 and the side cores 57, 58 combined in the front-rear direction X3 perpendicular to the height direction X1, and the bushing 13 penetrates the housing 12 in a clearance fit state and is integrally provided with the first flange portion 31 and the second flange portion 32 at both ends of the shaft portion 30. Therefore, it is not necessary to perform a process of assembling the bushing to the molded housing after the molding process of the housing as in the past, and the housing 12 and the bushing 13 can be integrally molded, which can suppress the increase in assembly man-hours and the increase in manufacturing cost. In addition, it is not necessary to have an assembly equipment for performing the assembly process, and it is also possible to suppress further increase in manufacturing cost.
[0115] As described above, according to the present embodiment, in the electrical connector 1, there are contacts 11 and a shell 12 for holding the contacts 11, and the shell 12 is provided with a through hole 26 for the bolt 101 (mounting component) to pass through, and the bolt 101 (mounting component) is used to install the shell 12 on the connector setting plate 100 (other components), and the shell 12 is installed on the connector setting plate 100 via the bushing 13. In this electrical connector 1, the increase in assembly man-hours can be suppressed, thereby suppressing the increase in manufacturing costs.
[0116] In the case where the shaft portion 30 of the bushing 13 is formed of a metal material other than a resin material, the housing 12 and the bushing 13 can be integrally molded by injecting resin into the mold 50 in a state where the material that becomes the shaft portion 30 of the bushing 13 is arranged in the mold 50. However, in the case of the present embodiment in which the shaft portion 30 of the bushing 13 is also made of a resin material and the entire bushing 13 is formed of the resin material, the housing 12 and the entire bushing 13 can be integrally molded by injection molding of the resin without having to arrange the material that becomes the shaft portion 30 of the bushing 13 in the mold 50 in advance.
[0117] In addition, according to the present embodiment, the first flange portion 31 and the second flange portion 32 are arranged to expand in a fan-shaped manner from the shaft portion 30 to the outside in the radial direction, so that the first flange portion 31 and the second flange portion 32 can be expanded and arranged with good spatial efficiency in the radial direction within a range where the first flange portion 31 and the second flange portion 32 do not overlap in the axial direction. Therefore, the area of the first flange portion 31 and the second flange portion 32 can be further enlarged.
[0118] In addition, according to the present embodiment, a pair of first flange portions 31 are provided and protrude in opposite directions in the radial direction, so the first flange portions 31 can be arranged to be spread in the radial direction at dispersed positions around the shaft portion 30. Therefore, the area of the first flange portion 31 can be further expanded in a dispersed state around the shaft portion 30. In addition, according to the present embodiment, a pair of second flange portions 32 are also provided and protrude in opposite directions in the radial direction, so the second flange portion 32 can be arranged to be spread in the radial direction at dispersed positions around the shaft portion. Therefore, the area of the second flange portion 32 can be further expanded in a dispersed state around the shaft portion 30.
[0119] The first flange portion 31 and the second flange portion 32 are formed by the side cores 55, 56, 57, and 58 together with the housing 12, so that a certain degree of clearance is provided between the housing 12 and the first flange portion 31 and between the housing 12 and the second flange portion 32. In addition, the bolt 101 (mounting member) inserted into the through hole 33 of the bushing 13 (which penetrates the through hole 26 of the housing 12 in a clearance fit state) is fixed to the connector setting plate 100 (another member), so that the housing 12 is mounted on the connector setting plate 100 via the bushing 13 in a state in which it can be displaced relative to the connector setting plate 100. At this time, if the clearance between the housing 12 and the first flange portion 31 and the second flange portion 32 is large, the housing 12 mounted on the connector setting plate 100 via the bushing 13 in a relatively displaceable manner, where the bushing 13 penetrates in the housing 12, is displaced greatly in a manner inclined relative to the shaft portion 30 of the bushing 13, and there is a possibility of damage. However, in the present embodiment, the housing 12 is provided with abutting portions 27 and 28 that protrude in the axial direction from the first flange portion 31 that is opposed to the connector setting plate 100 and abut against the connector setting plate 100. Furthermore, by the abutting of the abutting portions 27 and 28 of the housing 12 and the connector setting plate 100, the movement amount of the housing 12 toward the first flange portion 31 is limited, and the gap between the housing 12 and the second flange portion 32 is also reduced. Therefore, the housing 12 that is relatively displaceably mounted on the connector setting plate 100 via the bushing 13 can be suppressed from being displaced in a manner that is inclined relative to the shaft portion 30 of the bushing 13 at the portion of the housing 12 through which the bushing 13 passes. Thus, damage itself caused by the increase in the gap between the housing 12 and the first flange portion 31 and the second flange portion 32 can be prevented.

In the case where the shaft portion 30 is formed integrally with the metal bushing 13 and the housing 12, the metal shaft portion 30 is arranged in the mold 50 before the resin is injected into the mold 50. Then, the housing 12 and the bushing 13 are integrally molded by injecting and filling the resin into the mold 50 and curing it in a state where the metal shaft portion 30 is arranged in the mold 50. In addition, the bushing 13 is formed integrally with the shaft portion 30 at both ends in the axial direction of the metal shaft portion 30.

The first flange portion 31 and the second flange portion 32 may be formed in a shape other than a fan-like shape, for example, they may be provided so as to protrude radially from the shaft portion 30 in a rectangular plate-like shape. In the case where the first flange portion 31 and the second flange portion 32 protrude radially from the shaft portion 30 in a rectangular plate-like shape, they may be provided so as to protrude radially in the radial direction centered on the shaft portion 30, for example, they may be provided so as to protrude in a cross-like shape. In addition, in the case where the first flange portion 31 and the second flange portion 32 are provided so as to protrude radially in the radial direction, the first flange portion 31 and the second flange portion 32 may also be provided so as to protrude radially from the shaft portion 30 at positions that do not overlap when viewed from the axial direction of the shaft portion 30.
