  Conventionally, what is described in patent document 1 is known as a joint member for electrically connecting the specific electric wires contained in a wire harness. In this joint member, a plurality of terminal accommodating portions are arranged in parallel on the outer periphery of a band wound around a wire harness, and a conductive thin plate is arranged on the inner side thereof, and the electric wire side terminal fixed to the end of each electric wire Is inserted into each of the terminal accommodating portions, so that the electric wire side terminals come into contact with the conductive thin plate from the outside in the radial direction, whereby specific electric wires are electrically connected to each other via these electric wire side terminals. It is comprised so that.

Here, each electric wire side terminal has a leaf spring-like elastic portion for press-contacting with the conductive thin plate, and the electric wire side terminal is press-fitted into the terminal accommodating portion with the elastic portion elastically deformed.

JP-A-8-79948 (pages 2 and 3, FIG. 8)

  In the joint member described in the above-mentioned document, in order to ensure contact between the electric wire side terminal and the conductive thin plate, a leaf spring-like elastic portion having a large height is formed on the electric wire side terminal. Since the terminal accommodating part of the size which receives an elastic part is arranged in parallel with the band, the thickness of the whole joint member becomes quite large. Accordingly, when the wire harness is wound around the wire harness, the entire joint member protrudes greatly outward in the radial direction from the main body portion of the wire harness, which may interfere with the wiring harness.

  In view of such circumstances, an object of the present invention is to reduce the protruding amount of the joint member when the joint member is wound around a wire harness by reducing the thickness of the joint member.

As means for solving the above-mentioned problems, the present invention provides a joint member for electrically connecting a plurality of electric wires included in a wire harness, extending in one direction, and extending the longitudinal direction of the wire harness. A flexible wiring material having flexibility capable of being wound around the wire harness so as to be oriented in a circumferential direction or a direction inclined with respect to the same direction, and at a plurality of positions aligned in the longitudinal direction of the flexible wiring material, A joint-side terminal that protrudes outward from an edge extending in the longitudinal direction of the flexible wiring material and is connected to each of the electric wires is provided, and specific joint-side terminals among the joint-side terminals are electrically connected to the flexible wiring material. to a joint member connecting circuit contains for connecting certain of the wires included in the wire harness Is fixed to the wire terminal, and a plurality of wire-side terminals each joint terminal is fittable included in the joint member, and a plurality of wire-side insulating housing that holds the wire-side terminals, these wire-side insulation with retained between the wire-side terminals and the joint terminal of the joint member is configured so that both terminals by Rukoto fitted respectively are electrically connected to the housing, the wire-side in the fitted state The joint connector is configured so that the flexible wiring member of the joint member can be bent at a position between the insulating housings .

According to this joint connector, it is possible to connect the connection circuit of the joint member and the specific electric wire only by fitting each joint side terminal formed on the joint member and the electric wire side terminal fixed to the end of the specific electric wire. Can be easily performed. And in this state, by winding and fixing the flexible wiring material of the joint member around the wire harness main body part, a specific electric wire is electrically connected to each other, and a wire harness with a small protruding amount of the joint member is constructed. be able to.

  That is, in the present invention, since the joint member is configured by providing the joint-side terminal on the thin flexible wiring material, the entire joint member can be significantly thinned, and when this is wound around the wire harness The amount of protrusion of the joint member can be kept small.

Further, the joint connector includes a plurality of electric wire side insulating housings for holding the electric wire side terminals, and the electric wire side terminals held in these electric wire side insulating housings and the joint side terminals of the joint member are respectively fitted. In this state, the flexible wiring material of the joint member can be bent at a position between the electric wire side insulating housings.

  By providing such an electric wire side insulating housing, the insulation state of the electric wire side terminals outside the joint member can be more reliably maintained, and the electric wire side terminals that do not need to be short-circuited are short-circuited. The inconvenience that arises can be avoided more reliably.

  As the joint member, for example, a member in which a protruding portion constituting each joint-side terminal is formed on a conductor pattern of a flexible printed circuit substrate in which a conductor pattern is formed on a flexible substrate is preferable. It is. According to this configuration, it is possible to construct various connection circuits by setting the shape of the conductor pattern, and the degree of freedom in design is increased. By using a terminal, the structure can be simplified.

  In this case, if a reinforcing plate having a shape substantially matching the protruding portion is overlapped and fixed to the protruding portion of the conductor pattern, the joint side terminal is maintained while maintaining the flexibility and thin structure of the entire joint member. Effective reinforcement of the part can be performed.

  The flexible wiring material is a flat wiring material in which a flat insulating layer is formed around a plurality of conductors arranged in parallel on the same plane, and each conductor of the flat wiring material is integrated. A terminal component member extending in a direction substantially orthogonal to this may be connected, and these terminal component members may be arranged in the longitudinal direction of the flat wiring member to constitute the joint-side terminal.

  Also in this configuration, various connection circuits can be constructed by combining the connection of the conductor of the flat wiring member and the terminal component member, and the degree of freedom in design is increased.

  Moreover, it is more preferable that the unevenness | corrugation which increases the creeping distance between the said conductors is formed in the edge part of the longitudinal direction of the said flat wiring material. With this configuration, it is possible to more reliably prevent a short circuit between the conductors at the end.

Further, if the electric wire side insulating housing includes a plurality of electric wire side terminals that hold the electric wire side terminals in a state where the electric wire side terminals are arranged on substantially the same plane, they are integrated by the electric wire side insulating housing. A plurality of electric wire side terminals can be collectively fitted to the joint side terminals, and the connection workability is improved. Moreover, since this electric wire side insulating housing holds a plurality of electric wire side terminals in a state where these terminals are arranged on substantially the same plane, it can be made flat and thin, and the electric wire side Regardless of the introduction of the insulating housing, it is possible to keep the amount of protrusion when the entire connector is wound around the wire harness main body portion small.

  The wire-side insulating housing is a wiring material that holds the flexible wiring material of the joint member at a position where the wire-side terminal held by the wire-side insulating housing and the joint-side terminal of the joint member are respectively fitted. What has a holding | maintenance part is more preferable.

  According to this configuration, the flexible wiring material is held by the wiring material holding part on the electric wire side insulating housing side at the position where the electric wire side terminal and the joint side terminal are fitted, thereby fitting both terminals with a simple structure. The state can be reliably maintained.

  Specifically, the flexible wiring member constituting the joint member is provided with a through-hole, and the electric wire side insulating housing includes each electric wire side terminal held in the electric wire side insulating housing and the joint side terminal of the joint member. It is preferable that a wiring material holding projection that can be fitted into the through hole is formed at a position where the two are fitted.

  According to this configuration, the electric wire side insulating housing and the electric wire side terminal held by the electric wire side insulating housing are simply structured by simply fitting the electric wire side insulating housing side wiring material holding projection into the through hole formed on the flexible wiring material side. The relative position with the joint member can be fixed.

  Furthermore, by changing the relative position of the wiring material holding projection in each of the electric wire side insulating housings and the electric wire side terminal held in the electric wire side insulating housing for each electric wire side insulating housing, the joint side terminal and the electric wire side terminal Incorrect connection (a wire side terminal different from the wire side terminal to be connected to the joint side terminal is erroneously connected) is more reliably prevented.

  The joint connector includes a joint-side insulating housing that is fitted to each of the electric wire-side insulating housings, and is held by each electric wire-side insulating housing that is fitted to the joint-side insulating housing. If the joint side terminal fitted to the electric wire side terminal is held, the joint side insulation housing can hold the joint side terminals more reliably, and the joint side insulation can be more reliably prevented. By fitting between the housing and the electric wire side insulating housing, it becomes possible to collectively perform the fitting operation between each electric wire side terminal and the corresponding joint side terminal.

  Here, the joint-side insulating housing has a flexible wiring material holding portion that can be opened and closed, and this flexible wiring material holding portion allows insertion of each joint-side terminal into the joint-side insulating housing at its open position. In addition, it is preferable that the flexible wiring material connected to the joint side terminal is held by being closed from the open position to the closed position after the insertion.

  According to this configuration, each joint-side terminal of the joint member can be inserted into the joint-side insulating housing with the flexible wiring material holding portion opened, and the flexible wiring material holding portion is closed from that state. By holding the flexible wiring material, the flexible wiring material and the joint-side terminal can be protected.

Here, the joint-side insulating housings may be independent from each other. In this case, the joint-side insulating housings are largely displaced relative to each other, so that an external force in the shearing direction acts on the flexible wiring material. Become. On the other hand, if it is set as the structure by which the joint side insulation housings which mutually adjoin are connected via the flexible connection part which can bend in the same direction as the bending direction of the said flexible wiring material, it will be a joint by the said flexible connection part. By restricting the relative displacement between the side insulating housings, it is possible to protect the flexible wiring material, and it is possible to perform winding around the outer surface of the wire harness without inconvenience while bending the flexible connecting portion.

  Further, the present invention is a joint connector for electrically connecting a plurality of electric wires included in a wire harness, extending in one direction, the longitudinal direction of which is inclined with respect to the circumferential direction or the same direction of the wire harness. A flexible wiring material having flexibility that can be wound around the wire harness so as to be directed in a direction to be, a plurality of electric wire side insulating housings that hold electric wire side terminals fixed to the ends of the electric wires, and electric wires A joint-side insulating housing that can be coupled to the side-insulating housing, and an electric wire that is held by each joint-side insulating housing and is held by the electric-wire-side insulating housing in a state where the joint-side insulating housing is coupled to the electric-wire-side insulating housing. Fits with side terminals and can be connected to the flexible wiring material at the end opposite the fitting end A joint-side terminal having a wire connecting portion, and the joint-side insulating housing allows the wiring member connecting portion of each joint-side terminal to be electrically connected to the wiring member connecting portion. The joint-side terminal is held in an arrayed state, and the flexible wiring material is for electrically connecting specific wiring material connection portions among the wiring material connection portions connected to the flexible wiring material. A connection circuit is included.

  According to this configuration, by connecting the wiring material connecting portions of the joint side terminals held in each joint side insulating housing to the predetermined conductor in the flexible wiring material, the wiring material connecting portions of the specific joint side terminals are connected to each other. A joint member that is electrically connected via the flexible wiring member can be constructed. And, by coupling the joint side insulation housing holding each joint side terminal and the wire side insulation housing holding each wire side terminal and fitting the joint side terminal and the corresponding wire side terminal, It is possible to perform electrical connection between specific electric wires in the wire harness, and to wind and fix the joint connector around the outer peripheral surface of the wire harness.

  In particular, the electric wire side insulation housing holds a plurality of electric wire side terminals arranged in a substantially same plane, and the joint side insulation housing has a plurality of joint side terminals arranged in a substantially same plane. If it is configured to be held in an array that can be fitted to the corresponding electric wire side terminal, both the electric wire side insulating housing and the joint side insulating housing can be made flat, and these can be formed on the outer peripheral surface of the wire harness. The projecting dimension in the radial direction when wound around can be further reduced.

  Here, as each joint-side insulating housing, a flexible wiring material support portion provided at a position adjacent to the wiring material connection portion of each joint-side terminal in a direction orthogonal to the arrangement direction of the joint-side terminals. And having the flexible wiring material inserted between the flexible wiring material support portion and each wiring material connection portion, so that the flexible wiring material and each wiring material connection portion can be electrically connected. What is comprised is suitable.

  According to this configuration, by inserting and holding the flexible wiring material between the wiring material connection portions and the flexible wiring material support portion, the electrical connection work between the wiring material and the wiring material connection portions is performed. Can be made easier.

More specifically, each joint-side insulating housing is positioned in the vicinity of the wiring material connecting portion with a gap in which the flexible wiring material can be inserted between the joint-side terminal wiring member connecting portions. An electrode for welding a conductor of the flexible wiring material and each wiring material connecting portion in a state where the flexible wiring material is inserted into the gap in the flexible wiring material support portion. It is preferable that a through-hole for welding into which can be inserted is provided.

  According to this configuration, the electrode is inserted into the welding through hole of the flexible wiring material support portion while the flexible wiring material is inserted between the wiring material connection portions and the flexible wiring material support portion. Thus, electrical connection between each wiring member connecting portion and the corresponding flexible wiring member conductor can be performed by welding.

  In addition, the wiring member connecting portion of each joint-side terminal is a spring contact portion that is connected to the conductor by elastically contacting the conductor of the flexible wiring member with the flexible wiring member inserted into the gap. Some are also suitable.

  According to this configuration, the spring contact portion and the flexible wiring material can be utilized by using the elastic force of the spring contact portion only by inserting the flexible wiring material between the spring contact portions and the flexible wiring material support portion. It is possible to make electrical connection between them by bringing them into contact with a predetermined conductor.

  Each joint-side terminal has a press-contact blade that cuts into the insulating material of the flexible wiring material and press-contacts with an internal conductor as the wiring material connecting portion, and the joint-side insulating housing includes the press-contacting member. You may have a terminal support plate which supports the part of the joint side terminal in which the blade is formed from the opposite side to the press contact blade.

  Also in the joint connector shown above, the joint-side insulating housings arranged at positions adjacent to each other are connected via a flexible connecting portion that can be bent in the same direction as the bending direction of the flexible wiring member. More preferred.

  According to this configuration, the flexible wiring member can be protected by restricting the relative displacement between the joint-side insulating housings by the flexible connecting portion, and the outer surface of the wire harness while bending the flexible connecting portion. Winding around can be performed without inconvenience.

  The joint-side insulating housing has a flexible wiring material holding portion that can be opened and closed. The flexible wiring material holding portion exposes the wiring material connection portion of each joint-side terminal to the outside at the opened position and closes the flexible wiring material holding portion. In the position, it is more preferable that the flexible wiring material connected to each wiring material connecting portion is held at the open position.

  According to this configuration, after each of the wiring material connecting portions is electrically connected to a predetermined conductor of the flexible wiring material in a state where the flexible wiring material holding portion is opened, the flexible wiring material holding portion is closed to close the flexible wiring The flexible wiring material can be protected by holding the material.

  Among the joint connectors shown above, those having the electric wire side insulating housing and the joint side insulating housing are arranged so that the position of the insulating housing is shifted stepwise in a direction perpendicular to the longitudinal direction of the flexible wiring member. It is more preferable that the flexible wiring material is formed in a step shape.

According to such a joint connector, the wire harness body portion can be spirally wound, so that the number of joint side insulating housings and wire side insulating housings is larger than the outer peripheral length of the wire harness body portion. In many cases, these insulating housings can be wound without inconvenience while being deployed in the axial direction of the wire harness main body portion.
In addition, since there are no multiple insulating housings at the same position in the axial direction, for example, compared to a case where a joint connector is wound so that a plurality of insulating housings are arranged in the circumferential direction of the wire harness body portion, the substantial outer diameter of the wire harness Can be reduced.

  As described above, the present invention is configured such that the electric wire included in the wire harness is connected to the conductor of the flexible wiring material that can be wound around the wire harness via the joint side terminal, and the flexible wiring material includes the joint side terminal. Since the connection circuit for electrically connecting the specific joint side terminals is incorporated, the overall structure can be thinned and the amount of protrusion when the wire harness is wound around the wire harness can be kept small. is there.

Furthermore, the electric wire side insulation housing which holds the electric wire side terminal is provided, and the electric wire side terminal held by these electric wire side insulation housings and the electric wire side in the state where the joint side terminal of the joint member was fitted, respectively Since the flexible wiring material of the joint member can be bent at a position between the side insulating housings, the insulation state between the electric wire side terminals outside the joint member can be more reliably maintained. It is possible to more reliably avoid the inconvenience of short-circuiting the wire-side terminals that are not originally required to be short-circuited.

  A preferred embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows an example of a joint member 10 according to the present invention, which is composed of a flexible printed circuit substrate. In the illustrated joint member 10, a conductive pattern 14 is printed on a base material 12 made of an insulating material that is thin and extends in one direction. The conductor pattern 14 includes a protruding portion 14a that protrudes outward from an edge extending in the longitudinal direction of the joint member 10 to form a joint-side terminal, and a connection circuit for electrically connecting the specific protruding portions 14a to each other. It is included.

  In the example shown in the figure, six protrusions 14a are formed for three groups (18 in total). Further, in each group, a notch 12b is formed at the edge of the base material 12 opposite to the protruding portion 14a, and through holes 12a are formed at two positions sandwiching the notch 12b.

  Further, in this joint member 10, a comb-like reinforcing plate 16 having a projecting portion 16a substantially matching the projecting portion 14a is assigned to each group, and is superposed on the projecting portion 14a by bonding or the like. By being fixed, sufficient rigidity of the joint-side terminal constituted by each protruding portion 14a is ensured.

  On the other hand, a female terminal 20 is fixed to the end of each electric wire 18 constituting the wire harness as an electric wire side terminal. The female terminal 20 shown in the figure has a box-shaped electrical contact portion 22 that houses a spring contact piece 21 at the tip side, and a conductor barrel 24 that is crimped to a conductor portion of the wire 18 on the rear side, and a wire 18. And an insulation barrel 26 that is pressure-bonded to the insulating coating. Then, the appropriate protruding portion 14a of the joint member 10 (and the protruding portion 16a of the reinforcing plate 16 superimposed on the protruding portion 14a) is fitted into the electrical contact portion 22 of the female terminal 20 of the specific electric wire 18 and the By contacting the spring contact piece 21, the specific female terminals 20 are interconnected through a connection circuit formed by the conductor pattern 14 of the joint member 10.

  The reinforcing plate 16 is not necessarily required, and may be omitted as appropriate depending on the specifications. Further, the shape is not limited to a comb-like shape as shown in the figure, and it is also possible to use, for example, a simple plate-like reinforcing plate 16 'as shown in FIG. In that case, the protruding portion 14a and the reinforcing plate 16 'are sandwiched between the spring clamping pieces 28 using a wire side terminal 20' having a pair of spring clamping pieces 28 as shown in FIG. What should I do?

For example, the electric wire side terminals may be fitted one by one to the joint member 10, but a plurality of electric wire side terminals are housed in a dedicated electric wire side insulating housing for each group. If assembly is performed in units of housings in the final process of the wire harness, the assembly efficiency of the wire harness is remarkably improved and the insulation state between the wire side terminals outside the joint member 10 is more reliably maintained. Therefore, it is possible to more reliably avoid the inconvenience of short-circuiting between the wire-side terminals that originally do not need to be short-circuited.

  An example of the electric wire side insulating housing is shown in FIGS. The illustrated housing 30 is formed of an insulating material such as synthetic resin, and has a flat housing body 32, a thin plate-like cover 34 to be deposited thereon, and one end of the housing body 32 and the cover 34 relative to each other. It is integrally formed with a flexibly deformable thin-walled hinge portion 36 that is movably connected.

  The housing main body 32 has a plurality of (six in the illustrated example) terminal accommodating chambers 38 arranged on the same plane, and the projecting portions 14a of the joint member 10 shown in FIG. A terminal insertion hole 39 into which 16a can be inserted is formed. A lance 40 is formed on the top wall of each terminal accommodating chamber 38 to primarily lock the claw 23 to be locked in the electrical contact portion 22 of the inserted female terminal 20. A window 42 that opens the middle part upward is formed.

  Further, a wiring material support 44 for holding the flexible wiring material of the joint member 10 is extended from the end of the housing body 32 on the tip side (the side where the terminal insertion hole 39 is formed). . The wiring material support portion 44 is continuous with the housing main body 32 at a position immediately below each terminal insertion hole 39 and has a protruding dimension substantially the same as the width dimension of the joint member 10.

  A locking projection 44b is formed at the end of the wiring material support portion 44, and through holes 44a that penetrate the wiring material support portion 44 in the thickness direction are provided at two positions sandwiching the locking projection 44b. Yes. The locking projections 44b are fitted into the notches 12b of the joint member 10 in the terminal fitting state in which the protruding portions 14a and 16a of the joint member 10 are fitted to the female terminals 20 in the terminal accommodating chamber 38. The through hole 44a is provided at a position that matches the through hole 12a of the joint member 10 in the terminal fitting state.

  On the other hand, the cover 34 sandwiches the flexible wiring material of the joint member 10 between the main body cover portion 46 attached on the housing main body 32 in the closed state and the wiring material support portion 44 in the closed state. And a wiring material cover portion 48 to be integrated.

  A protrusion 47 that enters the window 42 in the closed state is formed on the back surface of the main body cover 46. These protrusions 47 come into contact with the electrical contact portion 22 of each female terminal 20 from the rear end side by entering the window 42 and realize secondary locking of the female terminal 20.

  A pair of wiring material holding pins (wiring material holding protrusions) 48 a that can be inserted into the through holes 12 a of the joint member 10 and the through holes 44 a of the wiring material support portion 44 are provided on the back surface of the wiring material cover portion 48. In addition, a lock frame portion 48 b that can be engaged with the lock protrusion 44 b is formed at the end of the wiring material cover portion 48. The cover 34 is locked in the closed position by the engagement of the locking projections 44b and the locking frame portion 48b, and the wiring material holding pins 48a are fitted into the through holes 12a of the joint member 10 in the closed position. The joint member 10 is held in the terminal fitting position (position where the protruding portions 14a and 16a are fitted to the female terminal 20) by being stuck.

  Therefore, according to this connector, the short-circuiting operation between the specific electric wires 18 in the wire harness can be easily performed by the following procedure.

  1) Each of the female terminals 20 is held in the electric wire side insulating housing 30 in the pre-process of the wire harness (FIG. 3).

  2) In the final step, the joint-side terminals, that is, the projecting portions 14a and 16a of the joint member 10 are fitted into the female terminals 20 with the cover 34 of each electric wire-side insulating housing 30 opened.

  3) The cover 34 is closed, the joint member 10 is sandwiched between the wiring material cover portion 38 and the wiring material support portion 44 of the cover 34, and the wiring material holding pin 48a is fitted into the through-hole 12a, whereby the wire side The joint member 10 is fixed to the insulating housing 30 to maintain the terminal fitting state (FIGS. 5 and 6).

  Further, instead of using the same electric wire side insulating housing 30 as shown in FIG. 5, the wiring material holding pins 48a and the electric wire side in the electric wire side insulating housings 30A, 30B, 30C used as shown in FIG. Incorrect connection between the joint-side terminal and the wire-side terminal by changing the relative position of the wire-side terminal held by the insulating housing for each wire-side insulating housing (the wire side to be connected to the joint-side terminal) It is possible to more reliably prevent a wire-side terminal different from the terminal from being connected by mistake.

  In the present invention, the number of the wire-side insulating housings 30 used is not limited, and the wire-side insulating housing 30 may hold only a single wire-side terminal. The specific structure for holding the flexible wiring material can also be set as appropriate. For example, instead of omitting the wiring material holding pin 48a, the wiring material is sandwiched between the wiring material support portion 44 and the wiring material cover portion 48. The holding function may be secured by strengthening the force.

  4) Since the joint member 10 can be bent and deformed at a position between the electric wire side insulating housings 30, the entire connector is wound around the main body portion of the wire harness W as shown in FIG. Specifically, the joint member 10 is wound around the body portion of the wire harness so that the longitudinal direction of the joint member 10 faces the circumferential direction of the wire harness W, and is fixed with the adhesive tape 50.

  Here, the joint member 10 is a very thin member made of a flexible wiring material, and each electric wire side insulating housing 30 is also a flat member that holds the female terminal 20 on the same plane. Even if the harness W is wound around the main body portion, the amount of protrusion is very small, and therefore the wire harness W can be routed in a narrow space without any inconvenience.

  In addition, although what used the flexible printed circuit base material as a flexible wiring material was shown in FIG. 1, this invention is other thin wiring materials, for example, what combined the some insulated wire, and the following A flexible flat wiring material can also be used.

  FIG. 9 shows a joint member 60 constructed using the flexible flat wiring member 61. The flexible flat wiring member 61 is formed by integrating a plurality of flat flat conductors 64 on the same plane in parallel with each other and covering them with an insulating coating layer 62. A through hole 62a into which the wiring material holding pin 48a of the electric wire side insulating housing 30 shown in FIG.

With respect to the flexible flat wiring member 61, a plurality of terminal constituting pins 66 corresponding to joint-side terminals are arranged in the longitudinal direction in a posture substantially orthogonal to the longitudinal direction of the wiring member, and an appropriate flat conductor 64 is provided. It is connected to the. Specifically, the front and back surfaces of the insulating coating layer 62 are locally removed at an appropriate location to form a window (opening) 62b, so that the flat conductor 64 is exposed through the window 62b. In a state where the terminal component pin 66 is in contact with the portion, both are joined by welding or the like through the window 62 b, and the pin tip portion 66 a constituting the terminal fitting portion of each terminal component pin 66 is the width of the flexible flat wiring member 61. Projects outward from one side edge of the direction.

  Even when such a joint member 60 is used, by fitting an appropriate electric wire side terminal (female terminal) to the pin tip portion 66a of each terminal constituting pin 66, the electric wire side terminals are connected to each other by a flat conductor 64. Can be electrically connected. Further, it is possible to freely design the connection circuit by combining the flat conductor 64 and the terminal component pin 66 connected to the flat conductor 64.

  In manufacturing the joint member 60, for example, as shown in FIG. 10, the insulating coating layer 62 of the flexible flat wiring member 61 is formed in a wide shape including the pin tip portion 66a of each terminal component pin 66 and used. If the insulating coating layer 62 is cut just before, for example, the broken line L shown in the figure, and the portion 67 outside the broken line L is cut off to project the pin tip portion 66a, the joint member 60 can be handled. It is possible to further increase the safety by preventing the pin tip portion 66a from hitting a finger or the like.

  Further, as shown in FIG. 11, if both end portions 66a of the terminal constituting pin 66 are projected outward from both edges in the width direction of the flexible flat wiring member 61 as terminal fitting portions, the terminal constituting pin 66 is provided. It is possible to substantially increase the number of terminals without increasing the number of pins.

  In addition, as shown in FIG. 12, a concave portion 62 c (or a convex portion) may be formed between the flat conductors 64 at the longitudinal end portion of the flexible flat wiring member 61 to increase the creepage distance between the flat conductors 64. If earned, it is possible to more reliably prevent short-circuiting between flat conductors due to condensation or the like.

  As a means for forming the terminal component pin connection window 62b in the insulating coating layer 62, various methods can be used.

  For example, as shown in FIG. 13, the insulating coating layer 62 may be irradiated with the laser beam LB to locally evaporate the insulating coating material in the region corresponding to the window 62b, or as shown in FIG. After making a pair of cuts 63 in the insulating coating layer 62 by the laser beam LB, the insulating coating portion between the cuts 63 may be removed to form the window 62b. The insulation coating portion may be removed by, for example, rolling the adhesive roller 80 as shown on the insulation coating layer 62 or attaching an adhesive tape to peel off the portion. You may make it blow off with high pressure air.

Here, any type of laser is applicable, such as a CO2 laser, a YAG laser, and an excimer laser. The advantage of such a laser is that any pattern can be peeled by controlling the irradiation position, and the maintenance period is long and easy to manage because of non-contact.

  As for the formation of the cut, for example, as shown in FIG. 15, the blade 84 of the die 82 having the blade 84 at a position corresponding to the cut position is pressed against the insulating coating layer 62, and only the insulating coating layer 62 is half-cut. You may make it cut.

The method of forming such a cut is excellent in productivity because the portion corresponding to the window 62b can be removed at once by using the adhesive roller or the like after the cut is formed, but it is excellent in productivity, but between the insulating coating layer 62 and the conductor. Since the removal of the insulating coating layer 62 becomes very difficult when an adhesive is present, it is preferable to use one without the adhesive.

  Next, an embodiment of a joint connector having a joint-side insulating housing will be described.

  FIG. 5 shows that the joint-side terminal is directly fitted to the wire-side terminal 20 held by the wire-side insulating housing 30, but the joint connector shown in FIGS. 16 and 17 is in the same plane. There are provided a plurality of joint-side insulating housings 70 for holding a plurality of joint-side terminals arranged in the figure (in the figure, the terminal constituting pins 66 of the joint member 60 shown in FIG. 9). The electric wire side insulating housings 30 corresponding to 70 are respectively fitted.

  As shown in FIG. 18, each joint-side insulating housing 70 has a pin press-fitting hole 71 into which each of the terminal component pins 66 can be press-fitted in an intermediate portion in the axial direction (left-right direction in the figure). An intermediate portion in the axial direction of each terminal component pin 66 is held by the joint-side insulating housing 70.

  A hood 72 is formed at one end of the joint-side insulating housing 70 so as to cover the pin tip 66a protruding from the pin press-fitting hole 71, and the wire-side insulating housing 30 is fitted into the hood 72. Thus, each electric wire side terminal (terminal fixed to the end of the electric wire 18) held in the electric wire side insulating housing 30 is fitted into the pin tip portion 66a. Further, a housing fitting lock portion 74 is formed at a proper position of the hood 72, and the housing fitting lock portion 74 is engaged with a proper position of the electric wire side insulating housing 30 in a state where the insulating housings 30 and 70 are fitted to each other. By fitting, the housing fitting state is locked.

  At the other end of the joint-side insulating housing 70, a wiring material holding portion for holding a flexible flat wiring material 61 (other flexible wiring materials may be used) coupled to the terminal constituting pins 66 is formed. Yes. Specifically, a wiring material support plate 75 that supports the flexible flat wiring material 61 from below is formed, and a cover 76 is provided above the wiring material support plate 75 so as to be openable and closable.

  The cover 76 is integrally connected to the housing main body through a thin hinge portion 76h, and is open to open the upper surface of the wiring material support plate 75 while being bent and deformed by the hinge portion 76h (FIG. 18). And a closed position (solid line position in FIG. 18) covering the upper surface. Locked portions 76a are formed on the left and right side portions of the rotating end portion of the cover 76. Correspondingly, the wiring member support plate 75 is engaged with the locked portions 76a. 75a is formed, and when the cover 76 is closed, the locked portion 76a and the locking portion 75a are engaged with each other so that the closed state is locked.

  Further, a wiring material restraining wall 76 b that protrudes downward is formed at the rotating end portion (rear end portion) of the cover 76, and when the cover 76 is closed, the wiring material restraining wall 76 b causes the flexible flat wiring material 61 to move. Restrained from the rear side.

  According to such a joint connector, predetermined electric wires 18 can be electrically connected to each other by the following procedure.

1) With the covers 76 of the joint-side insulating housings 70 opened, the terminal constituting pins 66 are press-fitted into the pin press-fit holes 71 from the cover 76 side, and the pin tip portions 66 a are projected into the hood 72. At this time, the flexible flat wiring member 61 to which each terminal component pin 66 is connected is placed on the wiring member support plate 75 of each joint-side insulating housing 70.

  2) Close the cover 76. As a result, the flexible flat wiring member 61 is sandwiched from above and below by the cover 76 and the wiring member support plate 75 and is also restrained from the rear side by the wiring member restraining wall 76b. That is, the flexible flat wiring member 61 is held and protected by the joint-side insulating housing 70.

  3) The electric wire side insulating housing 30 corresponding to each joint side insulating housing 70 is fitted. Along with this fitting, the wire-side terminal held in the wire-side insulating housing 30 is fitted into the terminal constituting pin 66 held in the joint-side insulating housing 70. Thereby, the predetermined electric wires 18 are connected to each other through the electric wire side terminals, the terminal constituting pins 66, and the flexible flat wiring member 61.

  Also in this configuration, the entire joint connector can be wound around the wire harness main body so as to bend the flexible flat wiring member 61 at a position between the insulating housings 30 and between the insulating housings 70. . Moreover, by fitting the insulating housings 30 and 70 together, the plurality of electric wire side terminals and the plurality of terminal constituting pins 66 can be fitted simultaneously, and the connection work is enhanced. In addition, by holding each terminal component pin 66 by the joint-side insulating housing 70, it is possible to more reliably prevent a short circuit between the terminal component pins 66.

  In the above embodiment, the joint side terminals such as the terminal constituting pins 66 are joined to the flexible wiring material such as the flexible flat wiring material 61 in advance to complete the joint member, and then the electric wire side insulating housing 30 and the joint side insulating housing 70 are used. However, the present invention is not limited to this, and joint-side terminals such as the terminal constituting pins 66 are previously held in the joint-side insulating housing 70, and the flexible wiring material is connected to the joint-side terminals in this state. An operation of electrically connecting the predetermined conductors may be performed.

  An example is shown in FIGS. The illustrated joint-side insulating housing 70 has the same configuration as that shown in FIGS. 16 to 18, but only the terminal component pin 66 alone (that is, the flexible flat wiring) in each pin press-fit hole 71. The pin rear end portion 66b on the opposite side of the pin front end portion 66a of the terminal component pin 66 as a wiring member connecting portion is horizontally arranged on the wiring member supporting plate 75 in a horizontal direction. Is arranged. Then, when the cover 76 is opened as shown in FIG. 19, the rear end portions 66b of the respective pins are exposed upward, and the flexible flat wiring member 61 is placed thereon, and a predetermined flat conductor of the flexible flat wiring member 61 is placed thereon. It is possible to electrically connect the rear end portion 66b of the pin to 64 by welding or the like (that is, complete the joint member 60 shown in FIG. 9), but after the connection, as shown in FIG. By closing 76, it is possible to hold the flexible flat wiring member 61 in the joint-side insulating housing 70 and protect it.

  According to such a configuration, the electrical connection between the pin rear end portions 66b of the terminal component pins 66 and the flexible flat wiring member 61 in a state where the plurality of terminal component pins 66 are held in a predetermined arrangement in the joint-side insulating housing 70 in advance. Connection is performed, there is an advantage that the connection work can be efficiently performed.

Further, by omitting the wiring material support plate 75 and arranging covers 76 in the vertical direction as shown in FIG. 21 to FIG. 23 (that is, double opening type), the pin rear end portion 6 in the open state is provided.
It becomes possible to further increase the degree of exposure of 6b. In this case, for example, as shown in the drawing, a pair of upper and lower wiring member sandwiching pieces 78 are extended rearward from the left and right sides of the main body of the joint-side insulating housing 70, and the flexible flat wiring member 61 is inserted between these wiring member sandwiching pieces 78. If the wiring member 61 is held in this manner, the connection work between the wiring member 61 and each pin rear end portion 66b can be facilitated.

  Further, if a terminal partition wall 76c interposed between the pin rear end portions 66b is provided on the back surface of the upper cover 76 as shown in the drawing, it is possible to more reliably prevent short circuit between the terminal constituting pins 66. It becomes possible.

  In addition, the specific opening / closing structure of the wiring member holding portion in the joint-side insulating housing 70 is not limited to the rotating type as described above, and may be, for example, a detachable structure as shown in FIGS. In the illustrated example, instead of the wiring material support plate 75 and the cover 76 shown in FIGS. 16 and 17, a flat cap 77 is detachably attached to the rear end of the main body portion of the joint-side insulating housing 70. The pin rear end portion 66b of each terminal component pin 66 is exposed to the outside in a state where the terminal plate 66 is removed, and the flexible flat wiring member 61 can be electrically connected thereto. By attaching to the rear end of the main body, the cap 77 can restrain the flexible flat wiring member 61 from the rear end and protect it (FIG. 26).

  A locking hole 77a is formed at an appropriate position of the cap 77, and a not-shown projection on the housing body side is fitted into the hole 77a so that the mounting state of the cap 77 is locked.

  When the wiring material support portion is provided in the present invention, various devices can be applied to facilitate the connection work between the flexible wiring material supported by the wiring material support portion and the joint side terminal.

  For example, in the joint connector in which the joint-side insulating housing 70 has the wiring material support plate 75 as shown in FIGS. 19 and 20, the plate is attached to the wiring material support plate 75 as shown in FIGS. A welding through hole 75h penetrating in the thickness direction (vertical direction in the figure) is provided at a position corresponding to the conductor 64 of the flexible flat wiring member 61, and a gap 86 between the wiring member support plate 75 and each pin rear end portion 66b. If the arrangement location of each conductor 64 of the flexible flat wiring member 61 inserted in is exposed downward through each welding through hole 75h, the welding electrode is inserted into the welding through hole 75h from below. As a result, in a state where the flexible flat wiring member 61 is supported on the wiring member support plate 75, the specific conductor portion and the pin rear end portion 6 that overlaps the specific conductor portion. b can be sandwiched from above and below by a pair of electrodes, and by applying a voltage between the electrodes, the pin rear end 66b and the predetermined conductor 64 of the flexible flat wiring member 61 can be welded. It becomes possible.

  Further, as a means for omitting such operations as welding and soldering, the conductor 64 of the flexible flat wiring member 61 supported by the wiring member support portion and the corresponding terminal constituting pin 66 elastically contact each other. A configuration is also possible.

The suitable example is shown in FIGS. A plurality of spring contact pieces 68 arranged in the axial direction are formed at the rear portion of each terminal constituting pin 66 (the portion exposed on the wiring material support plate 75). As shown in FIG. 33, each spring contact piece 68 has a shape that extends downward from the main body portion of the terminal constituting pin 66 and curves upward at an intermediate portion thereof. A protrusion for contact 68a protrudes. Then, the flexible flat wiring member 61 is inserted between the spring contact pieces 68 and the wiring member support plate 75 immediately below the spring contact pieces 68, so that each spring contact piece 68 is bent upward (elastically deformed). The contact projection 68a elastically contacts the upper surface of the flexible flat wiring member 61, and in the portion of the flexible flat wiring member 61 where the window 64b is formed in the insulating covering member 62 and the conductor 64 is exposed. The contact protrusion 68a is elastically brought into direct contact with the conductor 64 through the window 62b, whereby the terminal constituting pin 66 having the contact protrusion 68a and the conductor 64 are electrically connected. ing.

  According to such a configuration, the terminal configuration pin 66 and the flexible flat wiring member 61 can be electrically connected without performing the welding or the like. Further, as shown in the figure, the same number of spring contact pieces 68 are provided on all the terminal constituting pins 66 so that these terminal constituting pins 66 have a common shape, and the contact location is set at the position of the window 62b on the flexible flat wiring member 61 side. If set, it is possible to mass-produce the terminal component pins 66 and to reduce the cost thereof.

  In addition, it is also possible to connect each joint side terminal and the flexible wiring member using a press contact blade.

  Examples thereof are shown in FIGS. 34 and 35. Press contact blades 66s are formed at the rear portions (portions exposed on the wiring material support plate 75) of the respective terminal constituting pins 66 constituting the joint-side terminals by shifting their positions in the axial direction. Each press contact blade 66s has a forked shape and has a blade portion inside thereof, and protrudes upward from the main body portion of the terminal constituting pin 66. And the insulated wire 90 which comprises the said flexible wiring material is set to each press-contacting blade 66s from above, and the said press-contacting blade 66s cuts into the insulation coating layer of the said insulated wire 90 by pressing down, and the conductor inside it Thus, the conductor and the terminal constituting pin 66 having the press contact blade 66s are electrically connected.

  In this embodiment, a plurality of insulated electric wires 90 arranged in a specific direction form a flexible wiring material that can be bent and deformed in a direction orthogonal to the arrangement direction, and using the bending deformation, each of the embodiments described above is used. Similarly, it is possible to wind the wire harness main body part.

  By the way, the plurality of joint-side insulating housings 70 described above are arranged with a gap in a direction parallel to the arrangement direction of the terminal constituting pins 66 held in the housing 70, and the housings 70 are independent from each other. Therefore, the flexible wiring material is bent and deformed in the region between the joint-side insulating housings 70, so that it can be wound around the wire harness main body portion. When the relative displacement can be freely performed with respect to each other, the relative displacement applies a load in the shearing direction to the flexible wiring material.

  As a means for suppressing such a shear load, a structure as shown in FIGS. 36A and 36B is effective. In the figure, the hoods 72 and the covers 76 of the joint-side insulating housings 70 adjacent to each other are connected to each other via thin-walled flexible connecting portions 79. Each flexible connecting portion 79 can be bent and deformed in the same direction as the bending deformation direction of the flexible flat wiring member 61 held by each joint-side insulating housing 70. In the illustrated example, the three joint-side insulating housings 70 and these A flexible connecting portion 79 is integrally formed of a resin material.

According to such a structure, the relative displacement between the housings is suppressed by the mutual connection of the housings via the flexible connecting portion 79, whereby the flexible flat wiring member 61 (other flexible wiring members may be used). ) Is greatly reduced. In addition, since each of the bending deformation portions 79 can be bent and deformed in the same direction as the bending deformation direction of the flexible flat wiring member 61 in the region between the housings 70, the wire harness can be used without any inconvenience as in the case without the flexible connection portion 79. Winding around the main body can be performed.

  Further, in the present invention, various devices can be devised so that advantageous effects can be obtained even in the state after the winding.

  For example, like the joint-side insulating housing 70 shown in FIG. 37, if the edge of the boundary between the main body portion of the cover 76 and the wiring member restraining wall 76b at the rear end is rounded to have a smooth curved surface, the housing 70 is made of wire. It is possible to avoid inconvenience that the edge is caught when the wire harness is handled while being wound around the harness body.

  Further, when the joint connector is wound so that the housings 30 are arranged along the circumferential direction of the wire harness main body part as shown in FIG. 8, the number of the housings 30 that can be wound is the circumference of the wire harness main body part. Although limited by the length, if the joint connector is wound spirally around the wire harness main body, a large number of housings can be wound regardless of the circumferential length.

  A structural example for enabling such spiral winding is shown in FIG. The illustrated flexible wiring member 92 is formed in a step shape, and the insulating housings 30 and 70 are arranged for each step to hold the flexible wiring member 92 in the joint-side insulating housing 70 (as shown in FIG. 5). In the embodiment in which the joint-side insulating housing 70 is omitted, the insulating housings 30 and 70 are shifted in stages in the axial direction (shifted) by being held by the electric wire-side insulating housing 30 as shown in FIG. To be arranged).

  If such a joint connector is wound around the main body portion of the wire harness W as shown in FIG. 39, the housings 30 and 70 are arranged in a spiral shape while shifting their positions in the axial direction. A large number of housings 30 and 70 can be wound regardless of the peripheral length of the main body portion. In this case, as shown in FIG. 40, the tape 50 for fixing the joint connector may also be wound spirally.

  In the winding example shown in FIG. 8, the substantial outer diameter of the wire harness W is increased by twice the thickness of the housing 30, but in the winding state shown in FIGS. Since the positions of the housings 30 and 70 are shifted in the axial direction, there is an advantage that the substantial outer diameter can be reduced accordingly.

  As shown in this embodiment, in the present invention, the specific shape of the flexible wiring material can also be set as appropriate, and may be freely selected as long as it can be wound on the outer peripheral surface of the wire harness main body portion.

  Further, in the embodiment described above, the terminal constituting pin 66 constituting the joint side terminal is a male terminal, and the electric wire side terminal fitted to this is the female terminal 20. The side terminal may be a female terminal and the wire side terminal may be a male terminal.
