Abstract

PROBLEM TO BE SOLVED: To solve such problem that in a coaxial cable connector consisting of an external conductor, an insulator, and a terminal, the insulator is pressed into and fixed to the external conductor, which takes the connector long enough for pressing-in in a fit direction, therefore the pressing-in of the insulator prevents the reduction in profile of the connector.SOLUTION: In a coaxial cable connector having an external conductor, an insulator housed in the external conductor and a terminal installed in the insulator, the external conductor comprises a support part for locking a projection from one side at a position corresponding to the projection provided on a rear part of the insulator; and a claw part for locking a lock part provided on a front upper surface of the insulator from the other side, to fit the projection and the lock part into the support part and the claw part and to fix the insulator into the external conductor. Thereby the insulator can be fixed to the external conductor without pressing-in of the insulator, therefore a space (a distance in a fitting direction) required for pressing-in of the insulator for fixing can be saved.

Description

  The present invention relates to electrical connectors such as coaxial cable connectors. In particular, the present invention relates to a structure and method for accommodating and fixing an insulator on an outer conductor constituting a coaxial cable connector.

  In recent years, electronic devices such as mobile phones, notebook personal computers (PCs), and tablet PCs have been actively developed. In general, these electronic devices are manufactured to be small enough to be carried and carried and are convenient for users. Improvements are being made.

  As described above, as electronic devices become smaller in size, it is necessary to collect a large number of components in the electronic device, and various components incorporated in the electronic device must be made smaller and smaller. A coaxial cable is often used to connect high-frequency circuit components used in cellular phones, notebook PCs, tablet PCs, and the like that have become commonly used for communication in recent years. There is also a demand for miniaturization of the coaxial cable connector. In particular, there is a strong demand for a reduction in height to reduce the height of the coaxial cable connector. For example, the height of the connector during cable connection is required to be about 1 mm or less. However, considering the processing accuracy, strength, product standards, etc. of the parts, it is difficult to simply reduce the size of the connector and the cable, so it is necessary to reduce the height by devising the structure in the connector.

  As a coaxial cable connector intended for miniaturization, for example, there is a technique disclosed in Japanese Patent Application Laid-Open No. 2004-311452 (Patent Document 1). An L-shaped coaxial cable connector described in Patent Document 1 includes a terminal having a contact portion connected in contact with a corresponding contact portion (center terminal) of a coaxial connector for substrates and a connection portion to which a central conductor of the coaxial cable is connected; An insulator that supports the terminal so as to surround the terminal and an outer conductor that accommodates the insulator, and the height of the connection portion of the terminal disposed on the upper surface of the insulator is set smaller than the diameter of the dielectric of the cable. By doing so, the height dimension is reduced, and the height is reduced.

  The insulator accommodated in the outer conductor of the L-shaped coaxial cable connector described in Patent Document 1 has a cylindrical main body portion and an inner lid portion, and one of the outer sides radially outward from the upper surface position of the main body portion. And a shoulder portion is provided, and an inner lid portion is provided so as to extend at a peripheral portion on the opposite side of the outer side of the radius (that is, the tip side of the L-shaped coaxial cable connector). Furthermore, in order to accommodate and fix the insulator in the outer conductor, a protruding portion having a shape for hooking the main body portion of the insulator inside the cylindrical portion of the outer conductor is formed by embossing or the like. As another method of fixing the insulator to the outer conductor, one or more grooves are formed at the edge of the outer conductor, and the main body portion or the shoulder protruding portion constituting the insulator is formed in these grooves. A conventional method is to fix the insulator to the outer conductor by press-fitting.

JP 2004-311452 A

  However, the fixing method of the outer conductor and the insulator described in Patent Document 1 requires a space for forming a protruding portion inside the cylindrical portion of the outer conductor, and further press-fits firmly to fix. Such a space or distance (ie, the height of the outer conductor sufficient to press-fit and fix the insulator when the insulator is accommodated in the outer conductor) is coaxial. This hinders a reduction in the height of the cable connector (that is, a reduction in the height of the coaxial cable connector). Similarly, in the conventional method in which the protruding portion of the insulator is pressed and fixed into the groove at the edge of the outer conductor, a groove having a sufficient depth is formed in order to press-fit and firmly fix the protruding portion into the groove. Since a space is required, the height of the outer conductor must be increased due to such a space, which hinders a reduction in the height of the coaxial cable connector.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiment, and the repetitive description thereof will be omitted.

  FIG. 1 is a diagram showing each member in a state before assembly of a coaxial cable connector according to an embodiment of the present invention. In the coaxial cable connector according to the present embodiment, the extending direction of the coaxial cable and the fitting direction (inserting direction) of the board coaxial connector are substantially perpendicular to each other. Here, in order to simplify the description, in the fitting direction, the fitting side of the coaxial cable connector and the coaxial connector for a board is the lower side (lower side, lower side), and the opposite side is the upper side (upper side, upper side). To do. This coaxial cable connector (also referred to as an L-type coaxial cable connector) includes an outer conductor 100 that is electrically connected to a shielded wire of a coaxial cable (see FIG. 3), an insulator 200 that is accommodated in the outer conductor 100, and an insulator. The terminal 300 is integrally formed and embedded in the terminal 200 and is electrically connected to the central conductor of the coaxial cable.

  The outer conductor 100 is made by punching a metal plate made of a conductive material such as phosphor bronze and bending it. As shown in FIG. 1, the opening portion of the outer conductor 100 for fitting with the coaxial connector for a board is rounded so as to be substantially cylindrical, and a cylindrical portion 102 having a gap 104 at one place in the circumferential direction. , Two supporting arm portions 106 parallel to the fitting direction (vertical direction) with the coaxial connector for a board extending from the positions on both sides of the gap 104, and the gap 104 in the diametrically opposite side, The outer lid portion 108 is provided upright from the upper end of the cylindrical portion 102.

  The cylindrical portion 102 is a portion that accommodates the fitting portion 202 of the insulator 200 in a concentric position, and has a protruding seat portion 110 that receives the cylindrical portion 506 of the coaxial connector for substrate 500 on the inner surface by embossing or the like. Grooves 112 and 113 for fixing the insulator 200 when the insulator 200 is fitted into the outer conductor 100 are formed at the upper edge of the cylindrical portion 102 and the upper portion of the support arm portion 106. . Further, a groove 114 for fixing the insulator 200 is also formed below the support arm 106. In the embodiment shown in FIG. 1, the groove 113 is formed on the coaxial cable side (that is, rearward) with respect to the groove 114, and the groove 114 is formed near the base portion of the support arm 106. Further, a claw portion 115 is formed to be bent inward at a part of the upper edge of the cylindrical portion 102 and to be hooked and locked on the upper surface of the fitting portion 202 of the insulator 200. As described above, the grooves 112, 113, and 114 can function as a support portion for fixing and supporting the insulator 200 inside the outer conductor 100. In addition, a support part such as a groove part or a claw part can be formed on the support arm part.

  The outer lid portion 108 surrounds the constricted bent portion 116, a cylinder protective lid 118 that covers the cylindrical portion 102 when bent, a conductor protective lid 119 that covers the support arm portion 106, and the support arm portion 106 after bending. A fixing portion 120 for fixing the shielded cable, a shielded cable crimping portion 122 for encircling and electrically connecting the shielded wire of the coaxial cable, and an outer skin caulking portion 124 for caulkingly encircling the outer skin of the coaxial cable. The outer lid portion 108 is bent by a bent portion 116 that is a connection portion with the cylindrical portion 102 when connecting to the coaxial cable, and covers the coaxial cable.

  The cylinder protection cover 118 has side portions 126 that are bent downward at both ends when bent. Further, when the bent portion 116 is bent, a protruding portion 128 is formed on the inner surface by embossing or the like. When the outer cover 108 is closed, the protruding portion 128 hits the upper surface of the fitting portion 202 of the insulator 200, so that the fitting portion 202 can be firmly pushed into the cylindrical portion 102 and fixed. . The distance between the inner surfaces of the two side portions 126 is the same as or larger than the outer diameter of the cylindrical portion 102.

    The fixing part 120 of the conductor protective lid 119 has an extension part 130. After the bending part 116 is bent, the extension part 130 contacts the outer surface of the support arm part 106, and the extension part 130 is bent inward and supported. It is shaped so as to wrap around the arm portion 106.

  The shield wire caulking portion 122 has a side portion 132, and after the bent portion 116 is bent, the shield wire of the coaxial cable is caulked and electrically connected. In addition, since the projecting portion 134 is formed on the inner surface by embossing, the coaxial cable is difficult to be removed from the connector even if the coaxial cable is pulled in the extending direction after the caulking.

  The outer caulking portion 124 also has a side portion 136, and after the bent portion 116 is bent, the outer casing of the coaxial cable is caulked. In addition, since the protruding portion 138 is formed on the inner surface by embossing, the coaxial cable is made difficult to come out of the connector even if the coaxial cable is pulled in the extending direction after the caulking.

  The insulator 200 is made by molding an insulating material. As the insulating material, for example, a heat-resistant and flexible material such as a material in which liquid crystal polymer (LCP, liquid crystal polymer) resin is filled with a filler such as glass fiber, carbon fiber, or mica is used. The insulator 200 is roughly divided into a substantially cylindrical fitting portion 202 and a conductor support portion 204 extending from the fitting portion 202 in the extending direction of the coaxial cable radially outward. In order to simplify the description, on the straight line in the extending direction of the coaxial cable, the direction of the fitting portion 202 is the front (front end, front), and the direction of the conductor support portion 204 is the rear (rear end, rear). .

  The insulator 200 has an inner lid portion 206 that is located at a boundary portion between the fitting portion 202 and the conductor support portion 204 and extends upward. The inner lid portion 206 can be bent at the base portion and can be closed in the same direction as the outer lid portion 108. In one embodiment shown in FIG. 1, the inner surface (pressing surface) is formed in order to reduce the thickness of the base portion of the inner lid portion 206 so as to correspond to the curved surface portion 316 of the terminal 300 and to bend easily from the base portion. ) Has a slope. In addition, the slope which makes the thickness of the base part of the inner cover part 206 thin can also be provided in an outer surface.

  Further, the inner lid portion 206 only needs to be positioned closer to the conductor support portion 204 (that is, the rear side) than the central axis in the fitting direction of the fitting portion 202. In one embodiment shown in FIG. An intermediate lid portion 206 is provided on substantially the boundary between the conductor support portion 204 and the conductor support portion 204 (upper edge of the substantially cylindrical fitting portion 202).

  In a state where the inner lid portion 206 is opened, at least the connection portion 302 and the curved surface portion 316 of the terminal 300 are exposed. When the inner lid portion 206 is closed, the central conductor of the coaxial cable is sandwiched between the inner surface (pressing surface) of the inner lid portion 206 and the upper surface (connection surface) of the connection portion 302, so that the central conductor is connected to the connection portion 302. Although it is not necessary to solder, since the central conductor does not come out from between the inner lid part 206 and the connection part 302, the connection surface of the connection part 302 and / or the inner surface of the inner cover part 206 can be processed into irregularities. .

  A protrusion 208 that protrudes radially outward from the central axis of the fitting portion 202 is formed on the upper peripheral edge of the fitting portion 202 of the insulator 200. The protrusion 208 is provided at a position corresponding to the groove 112 of the outer conductor 100. Thereby, the protrusion 208 is held in the groove of the groove 112. In addition, projecting portions 209 projecting outward from upper side walls on both sides of the conductor support portion 204 are formed, and projecting portions 210 projecting outward from lower sidewalls on both sides of the conductor support portion 204 are formed. The protruding portions 209 and 210 formed on the side wall of the conductor support portion 204 are provided at positions corresponding to the grooves 113 and 114 of the external conductor 100 in order to sandwich the support arm portion 106 of the external conductor 100 from above and below. Further, the engaging portion 212 is formed by partially reducing the thickness of the fitting portion 202 in the fitting direction. The locking portion 212 is formed at a position corresponding to the position of the claw portion 115 formed by partially cutting the upper edge of the tubular portion 102 of the outer conductor 100 and bending the cut portion inward. For example, in the embodiment shown in FIG. 1, since the claw portion 115 is provided in the vicinity of the bent portion 116, the locking portion 212 is formed near the distal end side (the outer lid portion 108 side) of the fitting portion 202. . A locking portion 212 lower than the height of the fitting portion 202 is provided by processing the upper surface on the distal end side of the fitting portion 202 into a concave shape.

  The terminal 300 is integrally formed with the insulator 200, the connection portion 302 is open at the top, the contact portion (not shown) of the terminal 300 is open at the bottom, and a flat plate shape that connects the contact portion and the connection portion 302. The terminal 300 can be held by the insulator 200 by sandwiching the bridge portion (not shown) of the above by the insulator 200 from above and below. The upper edge of the contact portion and the upper surface of the bridge portion are each covered with the insulator 200, and can maintain an insulation state with the outer lid portion 108 of the external conductor 100.

  FIG. 2 is a view of the coaxial cable connector of one embodiment of the present invention after the insulator 200 is fitted into the outer conductor 100. The coaxial cable connector is assembled as follows. First, while the fitting portion 202 of the insulator 200 is accommodated in the cylindrical portion 102 of the outer conductor 100, the protrusions 208, 209, and 210 of the insulator 200 are inserted into the grooves 112, 113, and 114 of the outer conductor 100. By inserting (or fitting), the insulator 200 is accommodated in the outer conductor 100. Note that the terminal 300 is incorporated in the insulator 200 in advance by integral molding.

  Next, the central conductor of the coaxial cable is disposed at the connection portion 302 of the terminal 300. The coaxial cable is stripped in three stages using a stripper or the like, and is exposed in the order of the central conductor C1, the dielectric C2, the shield line C3, and the outer sheath C4 from the end of the coaxial cable (see FIG. 3). . Thereafter, when the outer lid portion 108 is bent and the lid is closed, the inner surface (inner surface) of the conductor protective lid 119 contacts the top of the surface of the middle lid portion 206 extending upward from the insulator 200. The inner lid portion 206 receives a pressing force from the inner surface of the conductor protection lid 119 and is closed together with the outer lid portion 108. When the outer lid portion 108 is closed, the cylinder protective lid 118 can cover the fitting portion 202 of the insulator 200, and the conductor protective lid 119 can cover the conductor support portion 204 of the insulator 200.

  When the outer lid portion 108 (in particular, the cylinder protective lid 118) of the outer conductor 100 is tilted so as to cover the cylindrical portion 102 and the fitting portion 202 of the insulator 200 accommodated therein, the bent portion 116 is bent. Let At that time, a pressing force is applied to the outer surface of the middle lid portion 206 of the insulator 200 by the cylinder protective lid 118 of the outer conductor 100. The inner lid portion 206 receives the pressing force, and the inner surface (that is, the pressing surface) of the inner lid portion 206 and the upper surface of the connecting portion 302 of the terminal 300 (that is, the connection surface for connecting the central conductor C1). ) Between the central conductor C1 of the coaxial cable.

  After that, the fixing portion 120 surrounds the support arm portion 106 so that the outer lid portion 108 is not opened, and the extension portion 130 is formed so as to wrap around the support arm portion 106, and the position of the outer lid portion 108 is changed. Fix it. Furthermore, the shield wire C3 is caulked and surrounded by the shield wire crimping portion 122, and the electrical connection between the shield wire C3 and the external conductor 100 is ensured. Further, the outer skin C4 is caulked and surrounded by the outer skin caulking portion 124, and the coaxial cable is fixed so as not to be detached from the connector. The center conductor C1 is pinched and the shield line C3 and the outer skin C4 are deformed by being crimped. However, the dielectric C2 is not pinched and is not crimped so that the shape is greatly deformed. Even if the coaxial cable is fixed to the connector, it does not deform. Therefore, there is little change in electrical characteristics such as the impedance of the cable when the connector is connected.

  The external appearance of the coaxial cable connector assembled according to the above process is shown in FIG. The overall flow of the coaxial cable connector assembly process is as described above. In the coaxial cable connector according to one embodiment of the present invention, a configuration for realizing a lower profile will be described in detail below. .

  FIG. 4 is a diagram illustrating a state where the fitting portion 202 of the insulator 200 is inserted into the tubular portion 102 of the outer conductor 100 in the assembly process of the coaxial cable connector. When manufacturing the coaxial cable connector, the terminal 300 integrally formed with the outer conductor 100 and the insulator 200 may be handled in a state of being connected to a metal plate (carrier) for easy handling. desirable.

  In the method of manufacturing the coaxial cable connector according to the embodiment of the present invention, first, as the first step, the two support arm portions 106 of the outer conductor 100 are expanded in the horizontal direction perpendicular to the fitting direction. As the next step, the fitting portion 202 of the insulator 200 is disposed obliquely above the tubular portion 102 of the outer conductor 100 and is placed below the claw portion 115 provided on the tubular portion 102. The position of the insulator 200 when it is inserted into the external conductor 100 is temporarily fixed by being brought into contact with the locking portion 212 provided on the outer surface. Note that the order of these two steps can be changed. Further, FIG. 4 shows a state in which an insulator is inserted from above the outer conductor 100, but in another embodiment, an insulator can be inserted from below the outer conductor 100.

  In the subsequent process, from the state shown in FIG. 4 (that is, a state where the engaging portion 212 is brought into contact with the claw portion 115 of the outer conductor 100 and the posture of the insulator 200 is temporarily fixed), the outer conductor 100 is moved into the outer conductor 100. Insert the insulator 200 completely. The state at this time is shown in FIG. FIG. 5 is a diagram illustrating a state in which the insulator 200 is accommodated in the external conductor 100 in a state where the two support arm portions 106 are expanded. When the insulator 200 is accommodated in the outer conductor 100, it is inserted into the grooves 112 formed at the upper edge of the cylindrical portion 102, the groove 113 at the upper edge of the support arm 106, and the groove 114 at the lower edge. The positions of the protruding portion 208 of the fitting portion 202 and the protruding portions 209 and 210 of the conductor support portion 204 are determined.

  As the last step, the two support arm portions 106 in the expanded state are returned to the original state (parallel state). When the support arm 106 is returned to the original position, it fits into the groove 112 formed on the upper edge of the cylindrical portion 102, the groove 113 on the upper edge of the support arm 106, and the groove 114 on the lower edge. The protruding portion 208 of the joint portion 202 and the protruding portions 209 and 210 of the conductor support portion 204 completely enter, and the outer conductor 100 can sandwich the insulator 200. The groove portions serve as support portions for locking the corresponding protrusions from one side.

  Thus, the insulator 200 is pressed by alternately pressing the locking portions 212 and the projecting portions 208, 209, and 210 of the insulator 200 from above and below by the claw portions 115 and the groove portions 112, 113, and 114 of the outer conductor 100. It can be firmly fixed to the outer conductor 100, and does not require a protrusion for hooking and fixing the insulator or press-fitting the insulator into the outer conductor as in the prior art. As a result, the height dimension of the outer conductor 100 and the insulator 200 can be shortened, and the height of the coaxial cable connector can be reduced.

  FIG. 6 is a transparent cross-sectional view of the outer conductor 100 containing the insulator 200. The claw portion 115 and the groove portion 114 of the outer conductor 100 hold down the locking portion 212 and the protruding portion 210 of the insulator 200 from above, and A mode that the groove parts 112 and 113 of the conductor 100 are supporting and pressing down the protrusion parts 208 and 209 of the insulator 200 from the bottom is shown.

  The thickness of the claw portion 115 of the outer conductor 100 in the fitting direction is substantially the same as the depth of the groove portion 112 in the fitting direction. The claw portion 115 is formed by being cut at substantially the same position as the bottom surface of the groove portion 112 and bent inside the cylindrical portion 102. With this structure, the height in the fitting direction can be used effectively.

  In the embodiment of the present invention shown in FIG. 6, the outer conductor 100 includes two claw portions 115, and correspondingly, there are also two locking portions 212 of the fitting portion 202 of the insulator 200. Is provided. Since the tips of the two claw portions 115 sandwich the tips of the convex step portions between the two locking portions 212 from the left and right side surfaces, the positioning of the insulator 200 in the rotational direction is performed when the coaxial cable connector is assembled. It can be done easily.

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiment. However, the invention is not limited to the embodiment, and various modifications can be made without departing from the scope of the invention. Needless to say.

  An electrical connector such as a coaxial cable connector has various uses. For example, it can be used for internal wiring of information equipment and electronic equipment in a wide range of industrial fields such as the information communication equipment industry and the automobile industry.
