An angle connector at least comprising: the connector includes a cylindrical member to be fitted to an object-side connector, an insulator to be accommodated in the cylindrical member in a state where a contact is held, and an end cap to guide a cable connected to the contact in a lead-out direction perpendicular to a fitting direction of the cylindrical member.

Description

Angle connector and cable harness

Technical Field

The present invention relates to an angle connector (angle connector) mounted on a terminal of a cable, and a cable harness including the angle connector, the angle connector including an end cap (end bell) for drawing out the cable in a direction perpendicular to a fitting direction of the connector and a mating connector.

Background

Conventionally, fig. 1 and 2 show a structure of a related art as an angle connector disclosed in japanese laid-open patent publication No. 2007-299649 (patent document 1). Fig. 1 shows a longitudinal cross section of an angle connector (this is referred to as a cable connector in patent document 1) in a state of being fitted into a receptacle as a mating connector, and fig. 2 shows a state in which each part of the angle connector is disassembled.

The plug 21 fitted to the mating connector 10 is inserted into the mounting nut 22. The plug 21 is fixed to the mounting nut 22 by 2 set screws 23. The mounting nut 22 is secured to the first end cap 24 by a retaining ring 25. The first end cap 24 is secured by 4 combination screws (sems screw)27 on the second end cap 26. A cable clamp 28 is secured to the second end cap 26.

The plug 21 has a plurality of contacts 21a and a housing 21b that holds the respective contacts 21 a. Holes 22a into which locking screws (locking screws) 23 are inserted are opened at two positions of the fitting nut 22. An O-ring 29 is located between the mounting nut 22 and the first end cap 24.

Fig. 3 is a perspective view of the first end cap 24 as viewed from the back side. The crimp terminal 31 is fixed to the inside of the first end cap 24 by a tapping screw (tapping screw) 32. The ground wire of the cable 33 is connected to the crimp terminal 31 in the arrow direction. A gasket (gasket)34 is positioned between the first end cap 24 and the second end cap 26.

In the angle connector 20, the first end cap 24 and the second end cap 26 are divided by a line A-A'. Therefore, after the cable 33 is inserted into the second end cap 26, the first end cap 24, and the fitting nut 22, the wiring work for connecting the cable 33 to the contacts 21a of the plug 21 can be easily performed.

Fig. 4 shows a state in which the cable 33 is inserted through the lead-out portion 26a of the second cap 26, the first cap 24, and the fitting nut 22, and the core portion 33a of the cable 33 is welded to each contact 21a of the plug 21. The front end of the bent portion 24a of the first cap 24 is inserted into the fitting nut 22.

According to the angle connector 20, the end cap from which the cable 33 is drawn in the direction perpendicular to the fitting direction of the angle connector 20 and the mating connector 10 is composed of two members, i.e., the first end cap 24 and the second end cap 26, which are divided by the line a-a'. Therefore, as shown in fig. 4, the cable 33 can be easily inserted into the end cap without bending the cable 33.

However, since the end cap is formed of two parts, the number of parts of the mold member increases. Further, as shown in fig. 1 and 2, the first and

second end caps

24 and 26 have complicated shapes. That is, the manufacturing cost of the angle connector 20 is high.

Further, a non-planar boundary between the first and

second end caps

24, 26 is required for the gasket 34 to be waterproof, rather than a simple and inexpensive O-ring. From this point of view, the manufacturing cost of the angle connector 20 is high.

Disclosure of Invention

The invention aims to provide an angle connector which can easily insert a cable into an end cover, can be manufactured more cheaply than the prior art and has a low-height structure.

The angle connector of the present invention at least comprises: the connector includes a cylindrical member to be fitted to an object-side connector, an insulator to be accommodated in the cylindrical member in a state where a contact is held, and an end cap to guide a cable connected to the contact in a lead-out direction perpendicular to a fitting direction of the cylindrical member.

According to the angle connector of the present invention, since the end cap is formed of one member, the number of parts is reduced, and a gasket for waterproofing the non-planar boundary is not required, so that the angle connector can be manufactured at low cost.

Further, since the angle connector of the present invention has a simple structure, a low-height angle connector can be realized.

Detailed Description

Embodiments of the present invention will be described with reference to the accompanying drawings.

Fig. 5A, 5B, 6A, 6B, and 6C show the appearance of the angle connector 100 of the embodiment. Fig. 7 shows a cross-sectional structure of the angle connector 100. Fig. 8 and 9 are exploded perspective views of the angle connector 100. Fig. 5A, 5B, 6A, 6B, 6C, and 7 show a state in which the cable 200 is attached to the angle connector 100.

The structure of the main portion constituting the angle connector 100 is explained with reference to fig. 8 and 9. In the following description, among the three orthogonal directions of X, Y, Z, the Z direction is a fitting direction in which the angular connector 100 is fitted to the mating connector, and the X direction is a drawing direction in which the cable 200 is drawn from the angular connector 100.

The central axis of a cylindrical barrel member (barrel)40 fitted to the target-side connector is parallel to the Z direction. The lower end surface (i.e., the front end surface in the Z direction) 40a of the cylindrical member 40 is parallel to the XY plane. The upper end surface (i.e., the rear end surface in the Z direction) 40b is parallel to a plane perpendicular to the XZ plane (i.e., a plane formed by the X direction and the Z direction) and intersecting both the Z direction and the X direction.

The flange 41 protrudes from the outer periphery of the substantially central portion of the tubular member 40 in the Z direction. A step portion 41a with a 1-step lower is formed on the outer periphery of the upper surface of the flange 41. The outer periphery of the cylindrical member 40 located below the flange 41 is formed with a groove 42. A linear slit 43 extending from the groove 42 to the lower end surface 40a is formed in the tubular member 40.

Three projections 44 project from the outer periphery of the upper end portion of the cylindrical member 40 at equiangular intervals. Each protruding portion 44 is formed with a screw hole 45 penetrating in the Z direction. One projection 44 of the three projections 44 is located at the highest position of the upper end portion of the barrel member 40. The upper surface of each projection 44 is parallel to the XY plane.

The end cap 50 has a substantially square cylindrical portion 51 having a central axis parallel to the X direction and an extension portion 52 continuous with the cylindrical portion 51, and has a hollow shape having a hollow portion 53 extending in the X direction as a whole. The lower surface of the extension portion 52 from the front end (in other words, the extension end) of the extension portion 52 to the vicinity of the rear end has a notched shape, and the hollow portion 53 opens in the Z direction. An inclined surface 54 is formed around the opening 53a of the hollow portion 53 opened in the Z direction by the notch, parallel to the upper end surface 40b of the cylindrical member 40, and coincident with the upper end surface 40 b.

An outer edge 55 for covering the three protrusions 44 of the tubular member 40 is formed on the outer periphery of the inclined surface 54. The upper surface and the lower surface of the outer edge portion 55 corresponding to each of the three protrusions 44 of the tubular member 40 are 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 in the annular inclined surface 54 (see fig. 7).

A pair of mounting portions 58 are formed on the outer periphery of the cylindrical portion 51. One of the mounting portions 58 projects in the Y direction, and the other of the mounting portions 58 projects in the opposite direction to the Y direction (i.e., -Y direction). Each mounting portion 58 is formed with a hole 58a penetrating in the X direction. A recess 58b connected to the hole 58a is formed in the center of each mounting portion 58 in the X direction.

The barrel member 40 and the end cap 50 are formed by, for example, an aluminum die casting machine.

The insulator (insulator) housed in the tubular member 40 is made of resin, and in this example, includes a cover insulator (cover insulator)60 and a base insulator (base insulator) 70.

The cap insulator 60 has a cylindrical outer periphery, and the central axis thereof is parallel to the Z direction. One end of the cover insulator 60 is an end portion (i.e., a front end in the Z direction) facing the target-side connector, and the one end includes a bottom plate portion 61, and the other end (i.e., a rear end in the Z direction) of the cover insulator 60 is open. Four holes 62 are formed in the bottom plate portion 61. A large diameter portion 63 having a slightly larger outer diameter is formed in the cap insulator 60 at a portion near the other end (i.e., the upper end).

The base insulator 70 includes a columnar portion 71 extending in the Z direction and a shaft-like protruding portion 72 protruding from one end of the columnar portion 71 in the opposite direction to the Z direction (i.e., -Z direction). The columnar portion 71 has four receiving portions 73. Each receiving portion 73 extends in the Z direction from one end of the columnar portion 71 to the other end thereof. The cross-sectional shape of each housing portion 73 is U-shaped. That is, each of the housing portions 73 has an inner wall surface having an arc-shaped cross-sectional shape.

When the four receiving portions 73 are referred to as a first receiving portion 73, a second receiving portion 73, a third receiving portion 73, and a fourth receiving portion 73 in the clockwise direction, the protruding strip 74 protrudes from the surface of the columnar portion 71 between the first receiving portion 73 and the second receiving portion 73, and similarly, the 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. The groove 75 is formed in the face of the columnar portion 71 between the second receiving portion 73 and the third receiving portion 73. The ridge 74 and the groove 75 extend in the Z direction from one end of the columnar portion 71 to the other end thereof. The cross-shaped projections 76 project from the lower end surface (i.e., the front end surface in the Z direction) of the columnar portion 71, and a pair of ends of the projections 76 are connected to the ribs 74. A groove-like recess 77 is formed in an inner wall of a middle portion of each housing portion 73 in the Z direction. The recess 77 extends along the inner wall around the axial direction in the Z direction. Of both ends of the recess 77, the end remote from the ridge 74 is connected to a notch formed in the thin-walled edge of the columnar portion 71.

In this example, the four contacts 81 are each barrel-shaped receptacle contacts. Each contact has a pair of projections 81a projecting outward at a middle portion in the longitudinal direction.

The angle connector 100 has, in addition to the barrel member 40, the end cap 50, the cover insulator 60, the base insulator 70, and the four contacts 81, a coupling nut (coupling nut)82, a wave spring (wave spring)83, a C-ring 84, an O-ring 85, 3 screws 86, a bush (bushing)87, a press cap (cap)88, and 2 sets of screws 91 and nuts 92, as shown in fig. 8 and 9.

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

< Assembly-1 >

(1-1) the cable 200 is passed through the press cap 88 and the sleeve 87.

(1-2) the cable 200 is inserted through the hollow portion 53 of the end cap 50 from the cylindrical portion 51 side of the end cap 50. The 4 core wires 203 are exposed by removing the coating of the leading ends of the coated wires 202 exposed from the sheath (sheath)201 of the cable 200. The covered wire 202 is bent and arranged in such a manner that the contacts 81 are easily soldered. Fig. 10A and 10B show this state.

(1-3) four contacts 81 are soldered to the 4 core wires 203.

(1-4) four contacts 81 are assembled in the four receiving portions 73 of the base insulator 70. By fitting the protruding portion 81a into the recessed portion 77 formed on the inner wall of the housing portion 73, each contact 81 is housed in the base insulator 70 in a state of being positioned on the base insulator 70.

(1-5) the columnar portion 71 of the base insulator 70 holding the contact 81 is inserted into the cylinder of the cap insulator 60. The inner peripheral surface of the cap insulator 60 has a shape conforming to the outer peripheral shape of the columnar portion 71 holding the contact 81. The inner surface of the bottom plate portion 61 of the lid insulator 60 has a shape corresponding to the lower end surface of the columnar portion 71 on which the cross-shaped protrusion 76 is formed. Therefore, the columnar portion 71 is accommodated in the cap insulator 60 in a state where the rotation in the circumferential direction is restricted. The front end of each contact 81 is located in the hole 62 of the bottom plate portion 61 of the cover insulator 60, and faces outward at that position.

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

< Assembly-2 >

(2-1) an O-ring (not shown in fig. 7, 8, and 9) is attached to the groove 42 of the tubular member 40 to secure waterproofing between the angle connector 100 and the mating connector.

(2-2) passing the upper end portion of the cylindrical member 40 through the wave spring 83, the wave spring 83 is placed on the step portion 41 a. When the upper end portion of the cylindrical member 40 having the three protrusions 44 is viewed in the Z direction, the outer diameter of the upper end portion of the cylindrical member 40 is larger than the inner diameter of the wave spring 83. Therefore, if the three projecting portions 44 project at the same position in the Z direction, the wave spring 83 cannot be caused to reach the step portion 41 a. However, in this embodiment, as described above, one projection 44 is located at the highest position of the upper end portion of the barrel member, and the other two projections 44 are located at relatively lower positions. Therefore, by decentering the wave spring 83 according to the height while passing through the barrel member 40, one or two of the projections 44 can pass through the wave spring 83 in the Z direction. Next, the upper end of the tubular member 40 is passed through the C-ring 84. As a result, the wave spring 83 and the C-ring 84 are placed on the step portion 41 a. The C-ring 84 is placed over the wave spring 83.

(2-3) passing the lower end portion of the tube member 40 through the coupling nut 82, the coupling nut 82 is positioned around the tube member 40. An inner peripheral stepped portion 82b is formed on the lower end side inner periphery of the coupling nut 82. Therefore, the inner diameter of the inner peripheral step portion 82b is smaller than the inner diameter of the upper end portion of the coupling nut 82. Further, an inner circumferential groove 82c is formed at an upper end portion of the coupling nut 82. Therefore, the inner diameter of the inner peripheral groove 82c is larger than the inner diameter of the upper end portion of the coupling nut 82. The coupling nut 82 is inserted into the inner peripheral step 82b to contact the lower surface of the flange 41 of the barrel member 40. At this time, for example, the distance between the open ends of the C-ring 84, that is, the outer diameter of the C-ring 84 is temporarily reduced by using an appropriate jig, and the C-ring 84 is released in a state where the C-ring 84 is accommodated in the inner peripheral groove 82C of the coupling nut 82. As a result, the C-ring 84 is fitted into the inner peripheral groove 82C. The Z-direction interval between the inner peripheral step 82b and the inner peripheral groove 82c of the coupling nut 82 corresponds to a dimension obtained by adding the thickness of the flange 41 of the tubular member 40 and the Z-direction height of the wave spring 83. In this state, the movement of the coupling nut 82 in the opposite direction to the Z direction (i.e., -Z direction) is restricted due to the contact of the inner peripheral step portion 82b with the lower surface of the flange 41, and the movement in the Z direction is restricted due to the C-ring 84 mounted on the upper side of the flange 41. In other words, the coupling nut 82 is captive by the C-ring 84. In this example, the coupling nut 82 has a triple screw (triple screw)82a on the inner periphery of the distal end side in the Z direction for fitting to the target-side connector.

< Assembly-3 >

(3-1) the cover insulator 60 in the above-described (1-6) state is attached to the above-described cylindrical member 40 in the above-described (2-3) state. The cap insulator 60 is held in contact with the stepped portion 46 (see fig. 7) formed on the inner peripheral surface of the tubular member 40 by the large diameter portion 63, and is prevented from coming off in the Z direction.

(3-2) the upper end surface 40b of the cylindrical member 40 is inserted into the groove 57 of the O-ring 85 fitted into the end cover 50. The three through holes 56 of the end cover 50 are inserted with 3 screws 86, and then screwed into the screw holes 45 of the tubular member 40. As a result, the cartridge member 40 and the end cap 50 are fixedly coupled to each other by screws. In this state, the protruding portion 72 of the base insulator 70 hits the inner wall of the extension portion 52 of the end cap 50. When the base insulator 70 is fitted to the mating connector, even if the base insulator 70 receives a force in the direction opposite to the Z direction (i.e., -Z direction) via the cover insulator 60, the base insulator 70 is prevented from moving (retreating) in the direction opposite to the Z direction (i.e., -Z direction), that is, the cover insulator 60 and the base insulator 70 are prevented from retreating.

(3-3) in a state where the sleeve 87 is sandwiched between the pressure cap 88 and the end cap 50, the pressure cap 88 is attached to the cylindrical portion 51 of the end cap 50 using 2 sets of screws 91 and nuts 92. The screw 91 is inserted through the through hole 88a formed in the press cap 88 and the hole 58a of the end cap 50, and is screwed into the nut 92 located in the recess 58b of the end cap 50. As a result, the hollow portion 53 of the end cap 50 is covered with the sleeve 87 to be waterproof.

As a result of the above steps, the connection of the cable 200 and the assembly of the angle connector 100 are completed, and the angle connector 100 with the cable 200 mounted thereon shown in fig. 5A, 5B, 6A, 6B, 6C and 7 is completed.

In this example, the cylindrical member 40 that guides the cable 200 to the fitting direction (i.e., Z direction) of the cylindrical member 40 and the cap 50 that guides the cable 200 to the drawing direction (i.e., X direction) perpendicular to the fitting direction are in close contact with each other at the boundary b by the upper end surface 40b and the inclined surface 54, and the boundary b is perpendicular to the XZ plane and intersects both the Z direction and the X direction. An O-ring 85 is disposed at the boundary b.

As shown in fig. 5A, 5B, 6A, 6B, 6C, and 7, the tubular member 40 and the end cap 50 are screwed to each other by 3 screws 86. The 3 screws 86 are located above the boundary b, 1 screw 86 of the 3 screws 86 is located on the rear side in the drawing direction with respect to the central axis of the tubular member 40, and the remaining 2 screws 86 of the 3 screws 86 are located on the front side in the drawing direction with respect to the central axis of the tubular member 40. That is, 1 screw 86 of the 3 screws 86 is located at an end edge in the opposite direction to the X direction (i.e., -X direction) above the boundary b. Of the 3 screws 86, 2 screws 86 are located on the side close to the pressure cap 88 and on both sides of the cable 200 with respect to the center axis of the barrel member 40 above the boundary b.

According to the angle connector 100 described above, the following effects can be obtained.

(1) Unlike the prior art in which the end cap is formed of two parts, the end cap is formed of one part, and therefore, the number of mold parts is reduced. Furthermore, no gaskets for waterproofing are required on the complex boundary between the two components constituting the end cap. Therefore, cost reduction can be achieved.

(2) When the cable 200 is inserted, the end cap 50 has a shape that does not require bending of the cable 200, as shown in fig. 10. Therefore, the insertion operation of the cable 200 can be easily performed.

(3) In the prior art angle connector 20 shown in fig. 1-4, a fitting nut 22 is used for coupling the plug 21 and the first end cap 24. In an embodiment, the fitting nut 22 is not used, and the barrel member 40 and the end cap 50 are directly fixed to each other by screws. Thus, a more significant low height angle connector can be achieved compared to the prior art. It should be noted here that in the angular connector 20 of the prior art, the plug 21 and the first end cap 24 cannot be directly screwed, or a low-height angular connector cannot be realized. In more detail, if the outer periphery of the barrel member (housing) included in the plug 21 in the angular connector 20 of the related art has a plurality of projections for screw fixation (this corresponds to the projection 44), the projections must be located at the same height as the plug 21, and therefore, the wave spring required for mounting the coupling nut included in the plug 21 cannot be mounted. If the heights of the projections are different, the height dimension of the header 21 itself must be significantly increased, and a low-height angle connector cannot be realized. On the other hand, according to the structure of the embodiment, since the boundary b of the barrel member 40 and the end cover 50 is inclined, the heights of the plurality of screws located above the boundary b are necessarily different from each other, and therefore, the barrel member 40 may have the plurality of protrusions 44 capable of mounting the small wave spring 83 in a limited dimension in the height direction as much as possible. In other words, in a limited space, the barrel member and the end cap can be combined together by screw fixation.

Since the cable harness includes the angle connector, cost reduction and downsizing can be expected.

Unless otherwise specified, the term "connected," and any variant thereof, means a direct or indirect connection between two or more elements, and may include the presence of one or more intervening elements between two elements that are "connected. The elements and connections between elements may be physical connections, electrical connections, or combinations thereof, as desired.

Ordinal terms, regardless of the ordinal definition, are not intended to limit the elements modified by or combined with the ordinal term by the order of the elements or the amount of the elements, unless otherwise specified. The use of ordinal numbers, unless otherwise indicated, is merely used as a convenient means of distinguishing between two or more elements. Thus, for example, the word "first X" and the word "second X" are expressions used to distinguish two Xs, and do not necessarily mean that the total number of Xs is 2, or that the first X must precede the second X. The term "first" does not necessarily mean "initially".

The terms "comprises (comprising)" and variations of the words used herein are used as non-exclusive representations. For example, the sentence of X containing a and B "does not deny that X contains a constituent element (e.g., C) other than a and B. In addition, when a certain sentence includes the term "include" or a sentence in which a word change is combined with a negative word, the sentence refers only to the object in which the term "include" or the word change is included. Therefore, for example, the sentence "X does not include a and B", and X may include a component other than a and B. Further, the term "or" is not intended to be exclusive logic.

The description of the embodiments of the present invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to all of the embodiments, and modifications and variations are possible. The embodiment was chosen and described to provide the best illustration of the principles of the invention and its practical application to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated.
