Description

  The present invention relates to a flat cable insertion technique.

In communication devices that transmit a large amount of information such as cellular phones and personal computers, coaxial cables are mainly used as cables that transmit high-frequency signals.
As shown in FIG. 17, a plurality of coaxial cables 300 are arranged in parallel in a plane, and a thin connector 301 is attached to both ends thereof (only one end side is shown in FIG. 17) to form a flat cable (or plug connector harness) I. To be.

  In various devices such as a mobile phone and a personal computer, a large amount of data is exchanged and processed between the components by connecting the electrical components among the various components constituting them with a flat cable I. In addition, the code | symbol 305 in FIG. 17 shows the other party connector provided on the board | substrate P which has a corresponding relationship with the connector 301 and is one of the electrical components of various apparatuses.

  18 to 20 show an example of a folding mobile phone to which the flat cable I is applied. The mobile phone 320 has a liquid crystal screen unit 320a on which an unillustrated camera is mounted on the outside, and an operation button unit 320b that displays and executes the operated content on the liquid crystal screen unit 320a, and is wired in the casing. The liquid crystal screen part 320a and the operation button part 320b are electrically connected by a flat cable I.

  The mobile phone 320 folds the liquid crystal screen part 320a with respect to the operation button part 320b side through the hinge part 324 connecting the liquid crystal screen part 320a and the operation button part 320b or turns the liquid crystal screen part 320a 180 degrees. A known rotary biaxial hinge structure that can be moved is employed.

  The hinge portion 324 can fold the liquid crystal screen portion 320a with the horizontal axis 326h as a rotation axis. Further, by inverting the liquid crystal screen 320a about the vertical axis 326v as a rotation axis, camera shooting can be performed at various angles. And what implement | achieves these operation | movement is the cylindrical hinge (cylindrical member) 328 which is flat at both ends opening located on the horizontal axis 326h and the vertical axis 326v.

  One cylindrical hinge 328 as one component of the mobile phone 320 is provided on the vertical axis 326v and two on the horizontal axis 326h (only one is shown on the horizontal axis 326h in the figure), and a liquid crystal screen ( 320a) is movable with respect to the operation button part (320b).

  By the way, in mobile phones, personal computers, and the like, further reduction in size and weight is desired. Naturally, the components of these devices are also affected, and the reduction in size is required. Even the cylindrical hinge 328 is no exception.

  It can also be seen that a flat cable I is passed through the cylindrical hinge 328 (see FIGS. 19 and 20).

The flat cable I is composed of several tens of coaxial cables 300, and connectors 301 are attached to both ends thereof. By the way, it is difficult to pass such a flat cable I through the cylindrical hinge 328 as it is because the flat cable I is large with respect to the through hole 328a of the cylindrical hinge 328. However, if the through hole 328a of the cylindrical hinge 328 is enlarged without changing the outer diameter of the cylindrical hinge 328, the thickness of the cylindrical hinge 328 is reduced, causing a problem in strength.

  Therefore, in order to pass the flat cable I through the cylindrical hinge 328 without changing the outer diameter of the cylindrical hinge 328 and without increasing the diameter of the through hole 328a, the connector 301 is attached to the coaxial cable 300. Then, only the coaxial cable 300 is inserted into the hole 328a, and then the connector 301 must be attached to the coaxial cable 300.

  However, in this case, it is necessary to connect the removed connector 301 to the coaxial cable 300 in a state where the cylindrical hinge 328 is externally fitted to several tens of coaxial cables 300, and the cylindrical hinge 328 becomes an obstacle. Therefore, it is difficult to connect the coaxial cable 300 and the connector 301.

  In addition, several tens of coaxial cables 300 are formed into a cylindrical shape by being passed through the cylindrical hinge 328, and the one that has been planar until then becomes three-dimensional. Therefore, in order to connect the flat cable I in the three-dimensional state to the planar connector 301, the distal end portion of the cylindrical coaxial cable 300 must be widened so that the workability is poor.

Furthermore, performing such work in a micro coaxial cable having a conductor diameter of 0.5 mm or less causes further deterioration in workability, so that a high level assembly technique is required.
JP2002-185586 JP2002-8765 Japanese Patent No. 3451393

  The present invention has been made in view of such circumstances, and the problem to be solved is to respond to the need for lightness, thinness and miniaturization in the market, and to connect a flat cable even with a connector attached to a coaxial cable. It is to provide a new technology that can be passed through a cylindrical hinge.

Therefore, the present invention employs the following means.
That is, the present invention provides a flat cable in which a plurality of cables are arranged in parallel and a flat cable having a connector attached to at least one end thereof is passed through a tubular member that is a component of various devices together with the connector. The connector has a notch portion that positions a start end portion of a cable winding portion formed by winding the cable around the connector inside the connector.

  According to the flat cable insertion structure of the present invention, the cable winding portion formed by applying the cable to the notch portion provided in the connector and winding the cable to some extent is the connector without the notch portion. The winding diameter is naturally smaller than when a cable is wound around. Therefore, when passing the coaxial cable together with the connector through the cylindrical member, it is not necessary to increase the diameter of the through hole of the cylindrical member.

Therefore, according to the present invention, it is not necessary to insert only the coaxial cable into the cylindrical member and then attach the connector to the coaxial cable to form a flat cable. That is, the flat cable can be passed through the cylindrical member while meeting the needs for lightness, thinness, and reduction in the market. For this reason, work efficiency is good.

Embodiments of the present invention (hereinafter referred to as embodiments) will be described with reference to the accompanying drawings.
In addition, the same code | symbol is attached | subjected to the same part as having demonstrated with the prior art, and description is abbreviate | omitted.

  As can be seen from FIGS. 1 to 4, the flat cable I has a connector 1 </ b> A and a plurality of cables 300 (described as coaxial cables 300 in the present embodiment).

  The connector 1A is attached to the housing 7 serving as a base, cable holders 8 and 10 which are attached to the housing 7 and hold a plurality of coaxial cables 300 in a state of crossing at the distal ends thereof. And an upper shell 12 covering the cable holders 8 and 10.

  The housing 7 is made of synthetic resin or other insulating resin. As can be seen from FIGS. 3 to 6, the main body portion 14 to which the front end portion 300 a (see FIGS. 5 and 6) of the coaxial cable 300 is attached, It has the insertion part 15 used as the junction part with the connector 5, and the contact 21 extended in the direction where the coaxial cable 300 is extended by the same number as the number of the coaxial cables 300 hold | maintained at the insertion part 15. FIG.

  The main body 14 has a flat rectangular hollow 16 (in particular, see FIG. 2) that opens upward and rearward at the center thereof, and support pillars 18 projecting into the hollow are opposed to the side walls 17 and 17, respectively. Is formed. The flat rectangular parallelepiped hollow portion 16 is divided with the support column 18 as a boundary. That is, the flat rectangular parallelepiped hollow portion 16 is divided into a front hollow portion 16a located on the insertion portion 15 side and a rear hollow portion 16b located on the opposite side. In this specification, the term “front and rear” refers to the front side of the insertion portion 15 in the extending direction of the coaxial cable 300 when the coaxial cable 300 is attached to the connector 1A, and the rear side to the opposite side. For example, the upper side and the lower side indicate an upper side and a lower side when facing each figure.

  The front hollow portion 16a and the rear hollow portion 16b communicate with each other and open upward. The rear hollow portion 16b also opens on the side opposite to the side where the insertion portion 15 is provided. The coaxial cable 300 extends rearward from a rear opening provided in the rear side hollow portion 16b of the flat rectangular parallelepiped hollow portion 16. The tip of the coaxial cable 300 is connected to the contact 21.

  The side part of the main body part 14 has wing piece parts 14a and 14a having locking grooves 14a1 (refer to FIGS. 2 and 3 in particular). Further, protrusions 14 d and 14 d are formed on both sides of the top end edge of the main body 14 of the housing 7. The locking groove 14a1 and the protrusion 14d will be described later.

  When the coaxial cable 300 is attached to the connector 1A, the coaxial cable 300 is in a state in which the outer skin of the distal end portion 300a is peeled and the signal line 306 and the external conductor 308 are exposed (see FIGS. 5 and 6). Specifically, the end portion 300a of the coaxial cable 300 has a portion where the external insulator 310 and the external conductor 308 are both peeled off and the signal line 306 is exposed, and a residual skin that is located immediately after the external insulator 310 remains. The portion 310a and the portion located immediately after the remaining skin portion 310a and only the external insulator 310 is peeled off and the external conductor 308 is exposed. The signal line 306 is obtained by coating the inner conductor 302 with the inner insulator 304.

The contact 21 comes into contact with a contact 51 (described later) of the counterpart connector 5 when the connector 1A is fitted to the counterpart connector 5 (see FIG. 1). The contact 21 has a press contact portion 21a to which the tip end portion 300a of the coaxial cable 300 is pressed (see FIGS. 5 and 6). The pressure contact portion 21 a is a portion that is located in the front hollow portion 16 a of the housing 7 and that the contact 21 is connected to the coaxial cable 300. When the contact 21 is connected to the coaxial cable 300, the pressure contact portion 21a breaks the internal insulator 304 of the signal line 306 of the coaxial cable 300 and is pressed into contact with the internal conductor 302 inside. The coaxial cable 300 and the contact 21 can be conducted.

  A plurality of through holes 22 are formed in the bottom plate portion of the rear side hollow portion 16b (see FIG. 4). The through hole 22 will be described later.

  The cable holder 8 corresponds to the front hollow portion 16a (see FIGS. 2 and 3), and is fitted to the front hollow portion 16a while holding the signal line 306 of the coaxial cable 300 (see FIG. 2). 3 and FIG. 4). When the cable holder 8 is fitted into the front hollow portion 16a, the inner conductor 302 of the distal end portion 300a of the coaxial cable 300 is press-contacted to the press-contact portion 21a of the contact 21 as described above.

  The cable holder 8 has a hollow rectangular parallelepiped shape that opens to the side (lower side) facing the housing 7. The front and rear walls 8a and 8b (see FIGS. 2 and 4) of the cable holder 8 have the same number of coaxial cables 300 as a plurality of holding grooves 24 for holding the signal lines 306, respectively.・ It is formed in a comb-like shape facing each other at 8b (see FIGS. 4 and 5; however, only the holding groove 24 formed on the rear wall 8b is shown). The holding groove 24 has an inverted U shape, and sandwiches the signal line 306 (see FIG. 4).

  The cable holder 10 corresponds to the rear-side hollow portion 16b (see FIGS. 2 and 3), and holds the external conductor 308 at the distal end portion 300a of the coaxial cable 300 and the external insulator 310 positioned immediately thereafter. In the state, it is fitted to the rear side hollow portion 16b (see FIGS. 2 to 6). In the present embodiment, the cable holder 10 is a channel-shaped hollow body that has an inverted U-shaped cross section and is open in the left-right direction. Note that the left and right are, for example, the left and right sides of the coaxial cable 300 facing the front end portion 300a side, that is, the left and right sides of FIG. 2 and FIG.

  The cable holder 10 has a front and rear walls 10a and 10b which are a pair of opposed walls which are opposed to each other when the cross-sectional shape at the time of assembly is an inverted U shape and the inverted U shape. A plurality of comb-like portions 26 are formed so as to have a comb shape. For example, reference numeral 10c shown in FIGS. 2 to 6 is a wall portion that connects the front and rear walls 10a and 10b, and is located on the upper side.

  Further, the outer conductor 308 of the coaxial cable 300 is inserted deeply into the slit 28 between the comb-like portions 26 on the front wall 10a, and the coaxial cable is inserted into the slit 29 between the comb-like portions 26 on the rear wall 10b. 300 external insulators 310 are inserted deeply and held, and the plurality of coaxial cables 300 are held in the housing 7 at a time in the held state. These slits 28 and 29 face each other and are formed in the same number as the number of coaxial cables 300.

  The plurality of through holes 22 formed in the rear hollow portion 16b (see FIG. 4) are formed corresponding to the comb-like portions 26. Specifically, copper or other good conductor (rectangular metal plate) 19 having excellent conductivity is attached to the rear side hollow portion 16b on the surface of the bottom plate portion (see FIGS. 4 to 6). A through hole 19a is formed, and a through hole 22 is formed in the housing 7 so as to be coaxial with the through hole 19a. Here, the good conductor 19 may be integrally molded with the housing 7 by overmolding or may be fitted into the housing 7.

  The upper shell 12 covers the housing 7 in contact with the cable holder 10 incorporated in the coaxial cable 300 (see FIGS. 1 and 3), and after connecting the connector 1A to the mating connector 5, the electrical contact is made. This is intended to strengthen the bond between the two.

  The upper shell 12 has an upper wall and left and right side walls bent in an L shape with respect to the upper wall. Therefore, the cross-sectional shape in a direction perpendicular to the front-rear direction is flat and has a substantially inverted U shape. Shell. Then, by inserting the housing 7 into the upper shell 12, the upper wall, the side wall, and a part of the lower surface of the housing 7 are held by the upper wall and the side wall. Bending pieces 12a and 12b bent inside the upper shell 12 are formed on the upper wall and the side wall.

  The bent piece 12a on the upper wall is in contact with the ceiling wall 10c of the cable holder 10 (see FIG. 6) and allows electricity flowing through the outer conductor 308 of the coaxial cable 300 to flow to the upper shell 12.

  Bending pieces 12b, 12b on the left and right side walls (only the bending piece 12b on the left side is shown in FIGS. 1 and 3) are for preventing the upper shell 12 from coming off from the housing 7. The wing piece 14a of the portion 14 is engaged with an engaging groove 14a1 extending in the height direction.

  Protrusions 12c, 12c, 12c, 12c for engaging with the mating connector 5 (on the upper wall in the drawing) on both sides of the upper wall tip of the upper shell 12 and on both sides of the side wall of the upper shell 12 parallel to the upper wall. Only the formed locking projections are shown.). The locking projection 12c will be described in the description of the mating connector 5.

  Furthermore, rectangular holes 12d and 12d are formed on both sides of the upper wall tip edge of the upper shell 12 so as to open to the front and fit with the protrusions 14d and 14d of the main body 14 of the housing 7 (see FIGS. 1 and 3). ). The upper shell 12 is prevented from being inserted into the housing 7 more than necessary by fitting the protrusion 14d and the rectangular hole 12d. The bent piece 12b of the upper shell 12 is locked to the locking groove 14a1 of the housing 7 by the fitting of the protrusion 14d and the rectangular hole 12d.

  In addition, the rear end edge of the upper wall of the upper shell 12 is bent downward, and is laid down in cross section to form an L-shaped hook-shaped portion 12e (see FIGS. 1 and 3). By forming the hook-shaped part 12e, a notch part 13 parallel to the rear edge is formed on the rear edge of the upper wall of the upper shell 12. The tip portion 300a of the coaxial cable 300 is pressed by the hook-shaped portion 12e, and the coaxial cable is prevented from being scattered.

Next, the counterpart connector 5 will be described.
The mating connector 5 is adapted to be fitted to the connector 1A, and covers the mating housing 49 (see FIG. 1) serving as a base and the entire mating housing 49, and is a flat hollow rectangular body having conductivity. The counterpart shell 50 soldered to the board P provided in the mobile phone 320, the counterpart housing 49 accommodated in the counterpart shell 50, the counterpart housing 49, and the contacts 21 of the connector 1A. The other party contact 51 which contacts. The same number of counterpart contacts 51 and contacts 21 are provided.

The mating shell 50 has a shape in which the central portion on the rear side is cut into a rectangle along its rear edge. On both sides of the rear end of the upper and lower walls of the mating shell 50, the locking holes 50c and 50c (in the drawing, the upper wall in which the locking protrusions 12c, 12c, 12c, and 12c described above are locked). Two locking holes 50c formed on the bottom wall and one locking hole 50 formed on the lower wall
Only c is shown. ) Is formed. Since the locking projection 12c and the locking hole 50c are locked, the connector 1A and the mating connector 5 are prevented from coming off.

  Further, one spring piece 52 is provided on each of the left and right side walls of the mating shell 50 for repellingly pressing both sides of the upper shell 12 of the connector 1A when mated with the connector 1A (FIG. 1). (Only the spring piece 52 on one side is shown). The spring piece 52 is energized between the connector 1 </ b> A and the mating connector 5 by contacting the upper shell 12. Therefore, when the connector 1A and the mating connector 5 are fitted, electricity flowing through the outer conductor 308 of the coaxial cable 300 is dropped on the board P, and the ground can be taken.

  Further, locking spring pieces bent into the hollows of the counterpart shell 50 are respectively provided in front of the spring pieces 52 on the left and right side walls of the counterpart shell 50 (on the side opposite to the side where the counterpart shell 50 is fitted with the connector 1A). 53 is provided (see FIG. 1). The locking spring piece 53 is engaged with an engaging portion (not shown) of the counterpart housing 49 by its elastic force to prevent the latch spring piece 53 from coming off from the counterpart housing 49.

  To assemble the connector 1A, as can be seen from FIGS. 5 and 2, the coaxial cable 300 is first held by the cable holder 8 and the cable holder 10. Thereafter, the cable holder 8 is fitted into the front hollow portion 16a of the housing 7 to press the signal line 306 into the pressure contact portion 21a, and the cable holder 10 is fitted into the rear hollow portion 16b to hold the cable. The tip end portion 26a of the comb-like portion 26 of the tool 10 is passed through the through hole 19a of the good conductor 19 and the through hole 22 of the housing 7, and then the tip end portion 26a is bent to prevent the tip portion 26a from coming off from the through hole 19a. . In this way, the coaxial cable 300 is assembled to the housing 7 (see FIG. 4).

  After the coaxial cable 300 having the cable holder 8 and the cable holder 10 is assembled to the housing 7, the upper shell 12 is moved closer to the housing 7 from the rear side of the coaxial cable 300 as shown in FIG. As can be seen from FIG. 1, the upper shell 12 is assembled to the housing 7 to form a flat cable I.

  Thereafter, the connector 1A and the mating connector 5 are fitted (see FIG. 1). As described in the background art, the contact 21 of the connector 1A and the mating contact 51 of the mating connector 5 are electrically connected. (See FIG. 1), a signal is transmitted from the operation button unit 320b side to the liquid crystal screen unit 320a via the coaxial cable 300 between the liquid crystal screen unit 320a and the operation button unit 320b of the mobile phone 320, and the operation button The contents operated by the unit 320b are displayed or executed on the liquid crystal screen unit 320a.

  As described above, the connector 1A is also attached to the other end of the coaxial cable 300, and is connected to the other connector 5 (not shown) provided on the operation button portion 320b of the mobile phone 320.

  Next, a flat shape with respect to the cylindrical hinge 328 described in the description of the background art, which is necessary as a pre-stage for electrically connecting the liquid crystal screen portion 320a and the operation button portion 320b of the mobile phone using the flat cable I. How to pass the cable I will be described with reference to FIGS.

As shown in FIG. 8 from the state of FIG. 7 which is a state before the flat cable I is passed through the cylindrical hinge 328, the coaxial cable 300 is placed in the upper state with a plurality of coaxial cables 300 being applied to the notches 13. While wrapping about a half turn so as to contact the upper surface of the shell 12, the coaxial cable is pulled backward to apply tension. In this state, the connector 1A in which the coaxial cable 300 is wound (the coaxial cable 300 is directed to the upper surface of the upper shell 12) is passed through the through hole 328a of the cylindrical hinge 328 as shown in FIG. ,
As shown in FIG. 10, the connector 328 is entirely pulled out from the through hole 328a to unwind the coaxial cable around the connector. Thereafter, the threaded connector 1A is connected to the counterpart connector 5. A portion where the coaxial cable 300 is wound about a half turn so as to come into contact with the upper surface of the upper shell 12 is referred to as a cable winding portion, and is denoted by reference symbol R. The starting end of the cable wrapping portion R is denoted by reference symbol R1.

  Next, with reference to FIG. 11 and FIG. 12, a difference in effect between the case where the notch portion 13 is formed in the upper shell 12 and the case where the notch portion 13 is not formed will be described.

  11 and 12 are both longitudinal sectional views of the connector. FIG. 11 is a longitudinal sectional view of the connector 1A according to the present embodiment in which the cutout portion 13 is formed in the upper shell 12. FIG. 12 is related to the background art. 3 is a longitudinal sectional view of a connector 301. FIG.

In both figures, the arc Ci is a virtual arc for comparing the sizes of the winding portions R.
In FIG. 11, it can be seen that the starting end R1 of the cable winding portion R is located closer to the center of the arc (inside the connector) than in FIG. For this reason, in the connector 1A, the winding diameter of the cable winding portion R formed by winding the coaxial cable 300 is reduced, and the cable winding portion R is accommodated in the arc Ci, but is cut into the upper shell 12. In FIG. 12 in which the notch portion 13 is not formed, it can be seen that the cable winding portion R does not fit within the arc Ci.

  Therefore, when considering the circular arc Ci as the through hole 328a of the cylindrical hinge 328, when the plurality of coaxial cables 300 are passed through the cylindrical hinge 328 together with the connector 1A, it is necessary to increase the diameter of the through hole 328a of the cylindrical hinge 328. In addition, it can be said that a flat cable insertion structure in which the cable I can be easily passed through the cylindrical hinge together with the connector without being forced into the cylindrical hinge 328 is realized.

  Therefore, it is possible to meet the needs for lightness, thinness and miniaturization in the market, and it is possible to pass the coaxial cable 300 through the cylindrical hinge 328 with the connector 301 attached to the coaxial cable 300, that is, with the flat cable I. it can. For this reason, work efficiency improves.

  The connector 1A is called a horizontal type that is connected to the counterpart connector by moving in the horizontal direction. On the other hand, what is connected by moving the connector in the vertical direction with respect to the counterpart connector is called a vertical type.

  FIG. 13 shows a vertical connector 1B and a mating connector 5B. The difference between the horizontal type and the vertical type is that, as described above, the direction in which the connector is connected to the mating connector is different, and therefore when the contact is horizontal, it is parallel to the housing. On the other hand, in the case of the vertical type, it is at a point perpendicular to the housing.

  Even in the vertical type, the notch 13 can be formed in the upper shell 12 as shown in FIGS. FIG. 15 shows a contact 11B in which the notch 13 is not formed in the upper shell 12.

  As is apparent from FIGS. 14 and 15, it can be seen that the distance L from the arc Ci of the starting end R1 of the cable winding portion R is greater in the contact 1B according to the present embodiment than in the contact 11B.

Therefore, in the case of the vertical type, the winding diameter of the cable winding portion R is reduced by forming the notch 13 in the upper shell 12 as in the horizontal type. As a result, as in the case of the horizontal type, a flat cable can be passed through the cylindrical hinge 328 without removing the connector 1, so that the work efficiency is good.

  Moreover, although the notch part 13 mentioned above was put in parallel along the side edge of the upper shell 12, even if it is diagonal with respect to the side edge of the upper shell 12 like FIG. Good. In this way, the depth of the notch 13 varies in the left-right direction, but when the connector 301 having the coaxial cable 300 wound around the through hole 328a of the cylindrical hinge 328 is inserted, some tension is applied to the coaxial cable 300. However, the coaxial cable 300 is difficult to be separated and easily passed (see FIG. 8). For this reason, since the plurality of coaxial cables 300 tend to be biased in the direction in which the tensile force is applied, the coaxial cable 300 is better accommodated when the depth of the notch is increased as it proceeds in the direction. Increasing the winding diameter of the portion R can be suppressed.

  Further, when the notch 13 is formed when the cable is wound around the connector, the operator determines which direction the coaxial cable should be wound around, using the notch 13 as a guide. In addition, if the notch 13 is slanted, it also serves as a guideline in which direction the described tension applied to the coaxial cable 300 described above should be set.

  In addition, the connector can be used only at both ends of the coaxial cable by using only the horizontal type or only the vertical type and mixing them.

  Further, the present invention is not limited to the illustrated examples described above, and it is needless to say that various modifications can be made without departing from the gist of the present invention.

  For example, in the present embodiment, the cylindrical hinge 328 has a cylindrical outer shape, but may have a prismatic shape or a coaxial cable, but other cables may be used. Even in the case, the same effect as described above is obtained.

It is a disassembled perspective view which shows the state just before connecting the connector which concerns on this invention to the other party connector. It is a disassembled perspective view which shows the state before connecting a coaxial cable to the housing of the connector which concerns on this invention. It is a figure which shows the state which coat | covers an upper shell to what connected the coaxial cable to the housing using the cable holder. It is the IV-IV line perspective view of FIG. It is a disassembled perspective view which shows the state before attaching a cable holder to a coaxial cable. It is the VI-VI sectional view taken on the line of FIG. It is a figure which shows the state before letting a coaxial cable pass to a cylindrical hinge with a connector.
