Description

Right angle connector and cable harness

The present invention relates to a connector installed at the end of a cable, which is a right-angle connector and a cable harness provided with a right-angle connector, and the right-angle connector is provided with pulling in a direction perpendicular to the mating direction of the connector and the mating connector Out the end bell of the cable.

1 and 2 show the structure disclosed in Japanese Patent Application Laid-Open No. 2007-299649 (Patent Document 1), which is a prior art of the right-angle connector. Fig. 1 shows a vertical section of a right-angle connector (this is referred to as a cable connector in Patent Document 1) in a mated state with a socket that is a counterpart connector, and Fig. 2 shows a state where the right-angle connector is disassembled into various parts.

The plug 21 fitted with the counterpart connector 10 is inserted into the mounting nut 22. The plug 21 is fixed to the assembling nut 22 by two fixing screws 23. The nut 22 is assembled and fixed to the first end band 24 by a retaining ring 25. The first end ferrule 24 is fixed to the second end ferrule 26 by four sems screws 27. The cable clamp 28 is fixed to the second end ferrule 26.

The plug 21 has a plurality of connectors 21a and a housing 21b that holds each connector 21a. At two places of the assembling nut 22, holes 22a for inserting a locking screw 23 are opened. An O ring 29 is provided between the mounting nut 22 and the first end band 24.

Fig. 3 is a perspective view of the first end band 24 viewed from the inside. The crimping terminal 31 is fixed to the inside of the first end ferrule 24 by a tapping screw 32. The ground of the cable 33 is connected to the crimp terminal 31 in the arrow direction. A gasket 34 is provided between the first end band 24 and the second end band 26.

In the right-angle connector 20, the first end ferrule 24 and the second end ferrule 26 are divided by a line A-A'. Therefore, the wiring work of connecting the cable 33 to each connector 21a of the plug 21 after inserting the cable 33 into the second end ferrule 26, the first end ferrule 24, and the assembling nut 22 is easy.

FIG. 4 shows that the cable 33 is inserted into the pull-out portion 26a of the second end ferrule 26 and the assembling nut 22 of the first end ferrule 24, and the core portion 33a of the cable 33 is welded to each connector 21a of the plug 21 state. The tip of the bent portion 24 a of the first end band 24 is inserted into the mounting nut 22.

According to the right-angle connector 20, the end ferrule for pulling out the cable 33 in the direction perpendicular to the mating direction of the right-angle connector 20 and the mating connector 10 is provided by the first end ferrule 24 divided by the AA' line It is composed of two parts with the second end hoop 26. Therefore, as shown in FIG. 4, the cable 33 does not need to be bent, and the work of inserting the cable 33 into the end band can be easily performed.

However, using two parts to form the end hoop will increase the number of mold parts. In addition, the first end band 24 and the second end band 26 have complicated shapes as shown in FIGS. 1 and 2. In other words, the manufacture of the right-angle connector 20 is more costly.

In addition, in the non-planar boundary between the first end ferrule 24 and the second end ferrule 26, a gasket 34 is necessary for waterproofing, instead of a simple and inexpensive O-ring. From this point of view, the manufacture of the right-angle connector 20 is more costly.

The object of the present invention is to provide a right-angle connector, which can easily perform the work of inserting the cable into the end ferrule, can be manufactured more cheaply than before, and has a low-profile structure.

The right-angle connector of the present invention includes at least a barrel body to be fitted with the mating connector, an insulator that is housed in the barrel body while holding the connector, and a cable connected to the connector in the mating direction of the barrel body The vertical pull-out direction guides the end hoop, the barrel body and the end hoop are closely connected to each other, and have a boundary along a plane that is perpendicular to the plane formed by the mating direction and the pull-out direction and is opposite to the mating direction and the pull-out direction The two sides crossed obliquely.

According to the right-angle connector of the present invention, the end ferrule is composed of one part, so the number of parts can be reduced, and there is no need to have a gasket for waterproofing on a non-planar boundary, so the right-angle connector can be manufactured inexpensively.

In addition, the right-angle connector of the present invention has a simple structure, so a low-profile right-angle connector can be realized.

The embodiments of the present invention will be described with reference to the drawings.

5A, 5B, 6A, 6B, and 6C show the appearance of the right-angle connector 100 of the embodiment. FIG. 7 shows the cross-sectional structure of the right-angle connector 100. As shown in FIG. 8 and 9 are exploded perspective views of the right-angle connector 100. 5A, 5B, 6A, 6B, 6C, and 7 show the state where the cable 200 is mounted on the right-angle connector 100.

The structure of the main parts constituting the right-angle connector 100 will be described with reference to FIGS. 8 and 9. In the following description, among the three orthogonal directions of X, Y, and Z, the Z direction is the mating direction of the right-angle connector 100 and the mating connector, and the X direction is the cable 200 being pulled out from the right-angle connector 100. Pull out direction.

The central axis of the cylindrical barrel 40 fitted with the mating connector is parallel to the Z direction. The lower end surface (that is, the front end surface in the Z direction) 40a of the barrel 40 is parallel to the XY plane. The upper end surface (that is, the rear end surface in the Z direction) 40b is perpendicular to the XZ plane (that is, the plane formed by the X direction and the Z direction) and parallel to a plane oblique to both the Z direction and the X direction.

The flange 41 protrudes from the outer periphery of the almost central part of the barrel 40 in the Z direction. On the outer periphery of the upper surface of the flange 41, a lower section 41a is formed. A groove 42 is formed on the outer periphery of the barrel body 40 below the flange 41. A linear slit 43 from the groove 42 to the lower end surface 40 a is formed in the barrel 40.

From the outer periphery of the upper end of the barrel body 40, the three protrusions 44 protrude at almost equal angular intervals. Each protrusion 44 is formed with a screw hole 45 penetrating in the Z direction. One of the three protrusions 44 is located at the highest position of the upper end of the barrel 40. The upper surface of each protrusion 44 is parallel to the XY plane.

The end band 50 has: a cylindrical portion 51 having a substantially square shape with the center axis positioned parallel to the X direction, an extension portion 52 connected to the cylindrical portion 51, and a hollow portion extending in the X direction as a whole 53 hollow shape. The lower surface of the extension part 52 from the front end (in other words, the extension end) of the extension part 52 to the vicinity of the rear end has a cut-out shape, and the hollow part 53 opens in the Z direction. In the vicinity of the opening 53a of the hollow portion 53 opened in the Z direction due to the notch, an inclined surface 54 that is parallel to the upper end surface 40b of the barrel 40 and fits with the upper end surface 40b is formed.

On the outer periphery of the inclined surface 54, an outer edge portion 55 for covering the three protruding portions 44 of the barrel body 40 is formed. The upper surface and the lower surface of the outer edge portion 55 corresponding to each of the three protrusions 44 of the barrel body 40 are each parallel to the XY plane, and a through hole 56 penetrating in the Z direction is formed in each portion. An annular groove 57 is formed on the annular inclined surface 54 (refer to FIG. 7).

A pair of attachment portions 58 are formed on the outer circumference of the cylindrical portion 51. One side of the mounting portion 58 protrudes in the Y direction, and the other side of the mounting portion 58 protrudes in the opposite direction of the Y direction (that is, the -Y direction). A hole 58a penetrating in the X direction is formed in each mounting portion 58. In the center part of each mounting part 58 in the X direction, a recess 58b communicating with the hole 58a is formed.

The above-mentioned barrel 40 and end band 50 are formed by die-casting aluminum, for example.

The insulator contained in the barrel 40 is made of resin, and in this example includes a cover insulator 60 and a base insulator 70.

The outer periphery of the mask insulator 60 is cylindrical, and its central axis is parallel to the Z direction. One end of the shield insulator 60 is the end facing the mating connector (that is, the front end in the Z direction). End) is open. Four holes 62 are formed in the bottom plate portion 61. A long-diameter portion 63 with a slightly longer outer diameter is formed near the other end (that is, the upper end) of the shield insulator 60.

The base insulating member 70 includes a columnar portion 71 extending in the Z direction, and a shaft-shaped protrusion 72 projecting from one end of the columnar portion 71 in the opposite direction to the Z direction (that is, the -Z direction). The columnar portion 71 has four receiving portions 73. Each accommodating portion 73 extends from one end of the columnar portion 71 in the Z direction to the other end thereof. The cross-sectional shape of each accommodating portion 73 is U-shaped. That is, each accommodating portion 73 has an inner wall surface whose cross-sectional shape is an arc shape.

When the four accommodating parts 73 are called clockwise the first accommodating part 73, the second accommodating part 73, the third accommodating part 73, and the fourth accommodating part 73, from between the first accommodating part 73 and the second accommodating part 73 A protruding strip 74 protrudes from the surface of the columnar portion 71, and similarly, a protruding strip 74 extending in the Z direction protrudes from the surface of the columnar portion 71 between the third receiving portion 73 and the fourth receiving portion 73. In addition, a groove 75 is formed on the surface of the columnar portion 71 between the second accommodating portion 73 and the third accommodating portion 73. The protrusion 74 and the groove 75 extend from one end of the columnar portion 71 to the other end in the Z direction. A cross-shaped protrusion 76 protrudes from the lower end surface of the columnar portion 71 (that is, the front end surface in the Z direction), and a pair of ends of the protrusion 76 is connected to the protrusion 74. A groove-shaped recess 77 is formed on the inner wall of the intermediate portion of each accommodating portion 73 in the Z direction. The recess 77 extends along the inner wall around the axis in the Z direction. Among the two ends of the recess 77, the end farther from the protruding strip 74 is connected to a notch formed in the thin-walled edge of the columnar portion 71.

Each of the four connecting members 81 is a cylindrical sleeve connecting member in this example. Each connecting member 81 has a pair of protrusions 81a protruding outward at the middle portion in the longitudinal direction.

The right-angle connector 100, in addition to the barrel body 40, the end ferrule 50, the shield insulator 60, the base insulator 70, and the four connecting members 81, as shown in FIGS. 8 and 9, also has: a coupling nut 82. Wave spring 83, C ring 84, O ring 85, three screws 86, bushing 87, cap 88, and two sets of screws 91 and nuts 92.

Next, the assembly of the right-angle connector 100 including the connection of the cable 200 will be described in sequence.

＜Assembly-1＞ (1-1) Pass the cable 200 through the cover 88 and the bush 87.

(1-2) The cable 200 is passed through the hollow portion 53 of the end ferrule 50 from the side of the cylindrical portion 51 of the end ferrule 50. The covering at the front end of the covered wire 202 exposed from the sheath 201 of the cable 200 is removed, thereby exposing the four core wires 203. The covered wires 202 are arranged in a flexural manner so as to be easily welded to the connecting member 81. Figures 10A and 10B show this state.

(1-3) Weld the four connecting pieces 81 to the four core wires 203.

(1-4) Assemble the four connecting members 81 to the four receiving parts 73 of the base insulating member 70. The protruding portion 81 a is inserted into the recess 77 formed on the inner wall of the receiving portion 73, thereby allowing the connecting members 81 to be received in the base insulating member 70 in a state of being positioned on the base insulating member 70.

(1-5) Insert the columnar portion 71 of the base insulating member 70 holding the connector 81 into the barrel of the mask insulating member 60. The inner peripheral surface of the shield insulator 60 has a shape that matches the outer peripheral shape of the columnar portion 71 holding the connector 81. In addition, the inner surface of the bottom plate portion 61 of the shielding insulator 60 has a shape that matches the lower end surface of the columnar portion 71 on which the cross-shaped protrusion 76 is formed. Therefore, the columnar portion 71 is housed in the mask insulator 60 in a state where the rotation in the circumferential direction is restricted. The front end of each connecting member 81 is located in the hole 62 of the bottom plate 61 of the shield insulating member 60, and faces the outside at this position.

(1-6) The O-ring 85 is inserted into the groove 57 formed by the inclined surface 54 of the end band 50.

＜Assembly-2＞ (2-1) An O-ring (not shown in FIGS. 7, 8, and 9) for ensuring waterproofness between the right-angle connector 100 and the counterpart connector is attached to the groove 42 of the barrel 40.

(2-2) The upper end of the barrel 40 is passed through the wave spring 83, and the wave spring 83 is placed on the segment 41a. The upper end of the barrel 40 with three protrusions 44 has an outer diameter of the upper end of the barrel 40 that is longer than the inner diameter of the wave spring 83 when viewed along the Z direction. Therefore, if the three protrusions 44 protrude at the same position in the Z direction, the wave spring 83 cannot reach the segment 41a. However, in this embodiment, as described above, one protrusion 44 is located at the highest position of the upper end of the barrel, and the other two protrusions 44 are located at a relatively low position. Then, the wave spring 83 is eccentric to pass through the barrel 40 in accordance with the height, thereby allowing one or two protrusions 44 to pass through the wave spring 83 in the Z direction. Next, the upper end of the barrel body 40 is passed through the C ring 84. As a result, the wave spring 83 and the C ring 84 are placed on the segment 41a. The C ring 84 is placed on the wave spring 83.

(2-3) The lower end of the barrel body 40 is passed through the coupling nut 82, and the coupling nut 82 is positioned around the barrel body 40. On the inner periphery of the lower end side of the coupling nut 82, an inner peripheral segment portion 82b is formed. Therefore, the inner diameter of the inner circumferential segment 82b is smaller than the inner diameter of the upper end of the coupling nut 82. In addition, an inner circumferential groove 82c is formed at the upper end of the coupling nut 82. Therefore, the inner diameter of the inner circumferential groove 82c is longer than the inner diameter of the upper end of the coupling nut 82. The coupling nut 82 is inserted until the inner peripheral segment 82b abuts against the lower surface of the flange 41 of the barrel 40. At this time, for example, use an appropriate jig to temporarily reduce the distance between the open ends of the C ring 84, even if the outer diameter of the C ring 84 is temporarily reduced, in the state where the C ring 84 is accommodated in the inner circumferential groove 82c of the coupling nut 82 Lower the liberation of the C ring 84. As a result, the C ring 84 fits into the inner circumferential groove 82c. The distance between the inner circumferential section 82b of the coupling nut 82 and the inner circumferential groove 82c in the Z direction is equivalent to the sum of the thickness of the flange 41 of the barrel 40 and the height of the wave spring 83 in the Z direction. In this state, the movement of the coupling nut 82 in the opposite direction to the Z direction (that is, the -Z direction) is restricted because the inner peripheral section 82b abuts against the lower surface of the flange 41, and the movement in the Z direction is subject to installation It is restricted by the C ring 84 above the flange 41. In other words, the coupling nut 82 is fixed by the C ring 84. In addition, the coupling nut 82, in this example, has a triple thread screw 82a for fitting with the mating connector on the inner periphery of the front end side in the Z direction.

＜Assembly-3＞ (3-1) Assemble the shield insulator 60 in the state (1-6) above to the barrel 40 in the state (2-3) above. The long diameter portion 63 is brought into contact with the segment 46 formed on the inner peripheral surface of the barrel 40 (refer to FIG. 7), thereby preventing the shield insulator 6 from being detached from the barrel 40 in the Z direction.

(3-2) Insert the upper end surface 40b of the barrel body 40 into the groove 57 of the end band 50 into which the O ring 85 is inserted. The three screws 86 are inserted into the three through holes 56 of the end band 50 and further screwed to the screw holes 45 of the barrel 40. As a result, the barrel body 40 and the end band 50 are screwed and fixed to each other. In this state, the protrusion 72 of the base insulating member 70 abuts against the inner wall of the extension 52 of the end band 50. When mating with the mating connector, even if a force in the opposite direction to the Z direction (ie -Z direction) is received by the base insulating member 70 through the shield insulating member 60, the base insulating member 70 is prevented from going to Z The movement (retreat) in the opposite direction of the direction (that is, the -Z direction), that is, prevents the mask insulator 60 and the base insulator 70 from retreating.

(3-3) With the cover 88 and the end band 50 sandwiching the bush 87, two sets of screws 91 and nuts 92 are used to attach the cover 88 to the cylindrical portion 51 of the end band 50. The screw 91 is inserted into the through hole 88 a formed in the cover 88 and the hole 58 a of the end band 50, and is screwed to the nut 92 located in the recess 58 b of the end band 50. As a result, the hollow portion 53 of the end band 50 is covered by the bush 87 to be waterproof.

As a result of the above sequence, the connection of the cable 200 and the assembly of the right-angle connector 100 are completed, and the right-angle connector 100 with the cable 200 installed as shown in FIGS. 5A, 5B, 6A, 6B, 6C, and 7 is completed.

In this example, the barrel 40 of the cable 200 is guided in the mating direction of the barrel 40 (that is, the Z direction) and the end band of the cable 200 is guided in the pull-out direction perpendicular to the mating direction (that is, the X direction) 50 is in close contact with each other at the boundary b, which is along a plane perpendicular to the XZ plane by the upper end surface 40b and the inclined surface 54 and obliquely intersecting both the Z direction and the X direction. An O ring 85 is arranged on the boundary b.

Moreover, the barrel body 40 and the end band 50, as shown in FIGS. 5A, 5B, 6A, 6B, 6C, and 7 are screwed and fixed to each other with three screws 86. The three screws 86 are located above the boundary b. One screw 86 of the three screws 86 is located on the rear side of the pull-out direction with respect to the central axis of the barrel 40, and the remaining two of the three screws 86 The screw 86, with respect to the central axis of the barrel 40, is located on the front side in the pull-out direction. That is, one screw 86 among the three screws 86 is located above the boundary b at the end edge in the opposite direction of the X direction (that is, the -X direction). Two screws 86 among the three screws 86 are located above the boundary b, with respect to the central axis of the barrel 40, on the side close to the cover 88, and are located on both sides of the cable 200.

According to the above-mentioned right-angle connector 100, the following effects can be obtained.

(1) Unlike the prior art in which the end hoop is composed of two parts, the end hoop is composed of one part, so the mold parts can be deleted. In addition, there is no need for a gasket for waterproofing the complicated boundary between the two parts constituting the end band. Therefore, it is possible to reduce costs.

(2) The end ferrule 50 has a shape that does not require bending the cable 200 as shown in FIG. 10 when the cable 200 is inserted. Therefore, the insertion operation of the cable 200 is easy.

(3) In the prior art right-angle connector 20 shown in FIGS. 1 to 4, in order to connect the plug 21 and the first end ferrule 24, an assembly nut 22 is used. In the embodiment, the assembling nut 22 is not used, and the barrel 40 and the end band 50 are directly connected to each other by screw locking. Thus, it is possible to realize a right-angle connector that is significantly lower than the prior art. It should be noted here that in the prior art right-angle connector 20, the plug 21 and the first end ferrule 24 cannot be directly screwed and fixed, or a flat right-angle connector cannot be realized. In detail, in the right-angle connector 20 of the prior art, if the outer circumference of the barrel (housing) contained in the plug 21 has a plurality of protrusions (this is equivalent to the protrusion 44) for screwing and fixing, the protrusion It must be at the same height of the plug 21, so it cannot be installed: a wave spring necessary to install the coupling nut contained in the plug 21. If the heights of the protrusions are different, the height dimension of the plug 21 itself must be significantly longer, and a flat right-angle connector cannot be realized. On the other hand, according to the structure of the embodiment, the boundary b between the barrel body 40 and the end band 50 is inclined, so the heights of the plurality of screw locks located above the boundary b will inevitably be different from each other. Therefore, the barrel body 40 can be Among the restricted dimensions in the height direction, there are a plurality of protrusions 44 on which the wave spring 83 as small as possible can be mounted. In other words, in the restricted space, the barrel body and the end band can be fixed by screw locking to be combined.

The cable harness is equipped with the above-mentioned right-angle connector, so cost reduction and miniaturization can be expected.

The connection between the elements and the elements is based on necessity, and physical connections are also acceptable, electrical connections are also acceptable, or a combination of these.

Ordinal numbers, unless otherwise specified, regardless of the definition of ordinal numbers, do not intend to limit the elements modified by ordinal numbers or combined with ordinal numbers by the order of the elements or the quantity of the elements. The use of ordinal numbers, unless otherwise specified, is simply used as a convenient narrative way to distinguish two or more elements. Therefore, for example, the sentence "1X" and the sentence "2X" are used to distinguish two Xs. The total number of Xs does not necessarily mean two, or it does not necessarily mean that 1X is before 2X. The term "No. 1" does not necessarily mean "initial".

The term "containing" and similar descriptions are used as non-exclusive descriptions. For example, the article "X contains A and B" does not deny that X contains elements other than A and B (such as C). Or, when there is a sentence that combines the term "contains" or its similar description with a negative word in a text, the text only refers to the term "contains" or its similar description. Thus, for example, the wording of "X does not contain A and B" is to recognize the possibility that X contains constituent elements other than A and B. In addition, the term "or" represents an illogical mutually exclusive OR.
