  A conventional coaxial connector is disclosed in Japanese Patent Application Laid-Open No. 2013-98122.

  9A and 9B show a coaxial connector 500 disclosed in Patent Document 1. FIG. However, the coaxial connector 500 includes a first connector (coaxial connector receptacle) 500A and a second connector (coaxial connector plug) 500B. FIG. 9A connects the first connector 500A and the second connector 500B. The previous state is shown, and FIG. 9B shows the state after the first connector 500A and the second connector 500B are connected.

  The first connector 500 </ b> A includes a cylindrical outer conductor (outer conductor portion) 101 and a center pin (center conductor portion) 102. The outer conductor 101 and the center pin 102 are insulated by an insulator 103. A lock groove 104 is formed on the outer periphery of the outer conductor 101. The first connector 500A is formed with a soldering portion (outer conductor) 105a and a soldering portion (center conductor) 105b extending in the planar direction. The soldering portions 105a and 105b are for soldering when the first connector 500A is mounted on a land electrode or the like of the substrate. The soldering portion 105 a is formed integrally with the outer conductor 101, and the soldering portion 105 b is formed integrally with the center pin 102.

  The second connector 500 </ b> B includes a cylindrical outer conductor (outer conductor portion) 106 and a socket (center conductor) 107. The outer conductor 106 and the socket 107 are insulated by an insulator 108.

JP 2013-98122 A

  The coaxial connector 500 has a structure in which the first connector 500A and the second connector 500B can be connected at all angles of 360 degrees. That is, in the connected state, the second connector 500B can be rotated 360 degrees with respect to the fixed first connector 500A.

  Therefore, the coaxial connector 500 has a structure in which the insulator 108 of the second connector 500B and the cylindrical outer conductor 101 of the first connector 500A do not interfere with each other. Further, the skirt portion 109 of the second connector 500B and the soldering portions 105a and 105b of the first connector 500A have a structure that does not interfere with each other. Therefore, the coaxial connector 500 has a problem that the height dimension of the coaxial connector 500 becomes large when connected to the first connector 500A and the second connector 500B. That is, since the second connector 500B must be able to rotate 360 degrees with respect to the fixed first connector 500A, the insulator 108 and the outer conductor 101 are provided with notches, and the notches of the two are connected to each other. By fitting, the height dimension at the time of connection is reduced, or the skirt portion 109 is provided with a notch, and the notch is fitted with the soldering portions 105a and 105b, thereby connecting the notch. The height dimension could not be reduced.

  Further, in the coaxial connector 500, the longer the skirt portion 109 of the second connector 500B is, the larger the so-called lead-in amount is, and the skirt portion 109 is likely to come into contact with the edge of the upper opening of the outer conductor 101 of the first connector 500A. The first connector 500A and the second connector 500B are preferable because they can be easily aligned. In other words, the ease of connection between the first connector 500A and the second connector 500B is that the leading amount S of the skirt portion 109 and the taper provided at the edge of the cylindrical portion of the outer conductor 101 are shown in FIG. Depending on the size of the sum of the lead-in amount T, there is a limit to increasing the lead-in amount T of the taper provided by utilizing the thickness of the outer conductor 101. It is preferable to increase the amount S.

  However, if the skirt portion 109 of the second connector 500B is lengthened, the skirt portion 109 and the soldering portions 105a and 105b of the first connector 500A interfere (contact). Therefore, in the coaxial connector 500, the minimum length of the skirt portion 109 is increased by increasing the height of the outer conductor 101 of the first connector 500A by a certain level and shifting the formation position of the lock groove 104 upward. Was secured.

  However, when the height of the outer conductor 101 is increased and the formation position of the lock groove 104 is shifted upward, the height dimension of the coaxial connector 500 when the first connector 500A and the second connector 500B are connected is increased. There was a problem of getting bigger. Even if the height of the outer conductor 101 is increased and the formation position of the lock groove 104 is shifted upward, the length of the skirt portion 109 has a limit, and a large amount of guiding can be secured. Therefore, there is a problem that it is difficult to align the first connector 500A and the second connector 500B.

  The present invention has been made to solve the above-described conventional problems, and as a means for the coaxial connector according to the present invention, a first connector including a first outer conductor and a center pin or socket; And a second connector having a socket or a center pin, and connecting the first outer conductor and the second outer conductor, and connecting the center pin of the first connector and the socket of the second connector Or the socket of the first connector and the center pin of the second connector are connected and used.

  Preferably, the first connector includes an insulator that fixes the center pin or socket of the first connector and is insulated from the first outer conductor, and at least one convex guide is formed on the insulator. . In this case, it is possible to increase the amount of protrusion of the convex guide, and it is possible to easily connect the first connector and the second connector. That is, the convex guide is not formed using an external conductor as in the prior art, but is formed using an insulator, so there is no restriction on the shape and size, and the amount of guidance is increased. The first connector and the second connector can be easily connected. In addition, since a recessed part is formed between convex guides and the recessed part and the insulator of a 2nd connector can be fitted, even if an insulator is provided in the 2nd connector, the 1st connector The height of the coaxial connector when connected to the second connector does not increase.

  It is preferable to provide four convex guides. In this case, the first connector and the second connector can be stably connected. Further, if the four convex guides are formed so as to be shifted by an angle of 90 degrees, the first connector and the second connector can be connected at four angles every 90 degrees.

  The center pin or socket of the first connector has a pin-shaped soldering portion, and an opening is formed between the outer edge of the insulator of the first connector and between the insulator and the inner portion, and the center pin or socket It is preferable that the soldering part is accommodated in the opening. In this case, a structure in which the center pin or the socket and the first outer conductor do not interfere with each other can be easily obtained.

  The second connector includes an insulator composed of at least one block for fixing the center pin or socket of the second connector and insulating from the second outer conductor, and a notch-shaped guide is formed in the insulator. It is preferred that In this case, it is possible to increase the amount of the notch-shaped guide, and the first connector and the second connector can be easily connected. Further, when the first connector and the second connector are connected, the notch guide and the convex guide of the first connector are fitted. Moreover, the recessed part formed between the convex guides of the 1st connector and the insulator of the 2nd connector are fitted. Therefore, the height dimension of the coaxial connector when the first connector and the second connector are connected to each other despite the provision of the convex guide on the insulator of the first connector and the insulator on the second connector. It won't get bigger.

  It is preferable to provide four notch guides. In this case, the first connector and the second connector can be stably connected. Further, if the four notch guides are formed so as to be shifted by an angle of 90 degrees, the first connector and the second connector can be connected at four angles every 90 degrees.

  In the coaxial connector of the present invention, the first lock claw of the first connector is formed in the inner portion of the first outer conductor that is slightly lifted from the mounting surface, and the second lock claw of the second connector is formed as the second outer conductor. Therefore, the height dimension when the first connector and the second connector are connected can be made extremely small.

  Four convex guides 31 are formed on the insulator 30 to facilitate the connection between the first connector 100A and the second connector 100B. The convex guide 31 is formed with a taper for leading into a circular outer periphery. Since the convex guide 31 is not formed on the outer conductor as in the conventional skirt portion, but is formed on the insulator 30, the degree of freedom in designing the shape and dimensions is high, and a large amount of guidance is provided.

This is to prevent the height dimension from becoming large.

  In addition, an opening 33 is formed between the outer edge of the insulator 30 and between the insulator 30 and the inherent portion 12. Then, the pin-shaped soldering portion 22 of the center pin 20 is accommodated in the opening 33. As a result, the center pin 20 and the first outer conductor 10 do not interfere with each other.

Each of the second outer conductor 40 and the socket 50 is made by processing a metal plate such as phosphor bronze, for example, and has a surface plated with Ni, Ag, Au, or the like. The insulators 60 and 70 are made of resin. The second outer conductor 40 and the insulator 60 are integrated by integral molding. Further, the socket 50 and the insulator 70 are integrated by integral molding. As described later, the integrated socket 50 and the insulator 70 are fixed to the second outer conductor 40 integrated with the insulator 60.

  In the second outer conductor 40, four stoppers 41 are formed by cutting and raising. The stopper 41 is for preventing the integrally formed insulator 60 from being detached from the second outer conductor 40.

  The second outer conductor 40 includes a cylindrical portion 42. The cylindrical part 42 is divided into four cylindrical pieces 42b by being divided by four notches 42a.

  A second lock claw 43 is formed inside each of the four cylindrical pieces 42b and in the vicinity of the tip. The second lock claw 43 is formed, for example, by forging or forging and bending the cylindrical portion 42 (cylindrical piece 42b) from the outside.

  The second outer conductor 40 includes a pair of plate-like caulking portions 44 for fixing the integrated socket 50 and insulator 70 by caulking.

  The insulator 60 has a cross shape in which a vertical structure 61 and a horizontal structure 62 intersect.

  The four outer portions of the intersecting portion between the vertical structure 71 and the horizontal structure 72 of the insulator 70 are provided with tapers so as to facilitate the connection between the first connector 100A and the second connector 100B. A guide 74 is formed. When connecting the first connector 100A and the second connector 100B, the notch-shaped guide 74 abuts on the convex guide 31 of the second connector 100B to facilitate the connection. The notch-shaped guide 74 is fitted to the convex guide 31 of the first connector 100A after connecting the first connector 100A and the second connector 100B.

  A pair of flanges 75 for caulking and locking the plate-like caulking portion 44 of the second outer conductor 40 is formed at the end of the insulator 70.

  A recess 76 for fitting the insulator 60 integrated with the second outer conductor 40 is formed on the back side of the insulator 70 (the side shown in FIG. 6B). The recess 76 is formed in a cross shape in accordance with the shape of the insulator 60.

  As described above, the socket 50 and the insulator 70 are integrated by integral molding. In the integrated socket 50 and insulator 70, the through hole 51 and the connection portion 52 of the socket 50 are arranged in the through hole 73 portion of the insulator 70. The socket 50 is fixed at both ends to the through hole 73 portion of the insulator 70, and the positions of the through hole 51 and the connection portion 52 do not wobble.

  Although not shown, a coaxial cable is connected to the second connector 100B. More specifically, the central conductor of the coaxial cable is connected to the socket 50. Further, the outer mesh conductor of the coaxial cable is connected to the second outer conductor 40.

  As described above, the integrated socket 50 and insulator 70 are fixed to the second outer conductor 40 integrated with the insulator 60.

  At the time of fixing, the cross-shaped recess 76 of the insulator 70 is fitted into the cross-shaped insulator 60. Therefore, the insulator 70 and the socket 50 are fixed to the second outer conductor 40 with extremely high positional accuracy.

  For fixing, both ends of the lateral structure 72 of the insulator 70 are locked to a pair of locking pieces 45 formed by cutting out the second outer conductor 40 in advance, and then the insulator 70 is slid, The front end of the vertical structure 71 of the insulator 70 is locked in advance with a locking piece 45 formed by cutting out the second outer conductor 40 in advance, and then a pair of plate-shaped caulking portions 44 of the second outer conductor 40. Is bent and crimped onto a pair of flanges 75 of the insulator 70.

  The first connector 100A and the second connector 100B having the above-described structure can be manufactured by a manufacturing method that has been widely used for manufacturing coaxial connectors. Briefly described, it is as follows.

  First, metal plates such as phosphor bronze, which are the respective materials of the first outer conductor 10 of the first connector 100A, the center pin 20, the second outer conductor 40 of the second connector 100B, and the socket 50, are prepared.

  Next, a punching process, a bending process, a drawing process, a cutting process, a forging process, and the like are appropriately performed on the prepared metal plate, and the first outer conductor 10, the center pin 20, the second outer conductor 40, and the socket. 50 is produced. In addition, these processes are normally performed in the state which connected the 1st outer conductor 10, the center pin 20, the 2nd outer conductor 40, and the socket 50 to the lead frame, respectively.

  Next, plating is performed on the surfaces of the first outer conductor 10, the center pin 20, the second outer conductor 40, and the socket 50, respectively.

  Next, a mold is prepared, and the first outer conductor 10 and the center pin 20 are accommodated in the mold, and then a resin is injected into the mold and cured, so that insulation having a predetermined shape is obtained. The body 30 is molded. Similarly, after the second outer conductor 40 is accommodated inside the mold, a resin is injected into the mold and cured to form the insulator 60 having a predetermined shape. Similarly, after accommodating the socket 50 in the mold, a resin is injected into the mold and cured to form an insulator 70 having a predetermined shape. These steps are also usually performed in a state where the first outer conductor 10, the center pin 20, the second outer conductor 40, and the socket 50 are respectively connected to the lead frame.

  Next, the first outer conductor 10 and the center pin 20 integrated with the insulator 30 are separated from the lead frame. Thereby, the first connector 100A is completed.

  Similarly, the second outer conductor 40 integrated with the insulator 60 is separated from the lead frame. Further, the socket 50 integrated with the insulator 70 is separated from the lead frame. Next, the integrated socket 50 and insulator 70 are fixed to the second outer conductor 40 integrated with the insulator 60, and the second connector 100B is completed. Then, a coaxial cable (not shown) is connected to the completed second connector 100B.

  As described above, the coaxial connector 100 including the first connector 100A and the second connector 100B is completed.

  Next, a method for connecting the first connector 100A and the second connector 100B will be described with reference to FIGS. FIG. 7A is a cross-sectional view showing the first connector 100A and the second connector 100B before being connected. FIG. 7B is a cross-sectional view showing the first connector 100A and the second connector 100B after being connected. FIG. 8 is a cross-sectional view of a main part of FIG. 7B partially enlarged.

  First, as shown in FIG. 7A, the side of the first connector 100A on which the center pin 20 is formed and the side of the second connector 100B on which the socket 50 is formed are opposed to each other. 2 connector 100B is arranged. At this time, the first connector 100A is already mounted on a substrate or the like. Further, as described above, a coaxial cable (not shown) is connected to the second connector 100B.

  Next, the second connector 100B is moved closer to the first connector 100A.

  As a result, first, the circular outer peripheral portion of the convex guide 31 of the first connector 100A comes into contact with the cylindrical piece 42b of the second outer conductor 40 of the second connector 100B. Furthermore, when the second connector 100B is moved closer to the first connector 100A, the cylindrical piece 42b of the second outer conductor 40 slides while being guided by the taper of the circular outer peripheral portion of the convex guide 31; The central axis of the first connector 100A and the central axis of the second connector 100B exactly coincide.

  Further, when the second connector 100B is brought closer to the first connector 100A, as shown in FIGS. 7B and 8, four convex guides 31 and four notch guides are provided. 74, the four recesses 32, the vertical structure 71 and the horizontal structure 72 of the insulator 70 are fitted, and the connection portion 21 of the center pin 20 is inserted into the through hole 51 of the socket 50. The four cylindrical pieces 42b are inserted into the four through holes 14, and the respective first lock claws 15 and the respective second lock claws 43 are engaged to complete the connection between the first connector 100A and the second connector 100B. To do.

  The coaxial connector 100 according to the embodiment described above has the following features.

  In the coaxial connector 100, the first lock claw 15 of the first connector 100A is formed in the inner portion 12 of the first outer conductor 10 slightly lifted from the mounting surface, and the second lock claw 43 of the second connector 100B is formed. Since the second outer conductor 40 is formed near the tip of the cylindrical piece 42b, the height dimension when the first connector 100A and the second connector 100B are connected is extremely small.

  In the coaxial connector 100, the convex guide 31 is formed in the insulator 30, the notch guide 74 is formed in the insulator 70, and is not formed on the external conductor like the skirt portion which is a conventional guide. Furthermore, the degree of freedom in designing the shape and dimensions of the convex guide 31 and the notch guide 74 is high, and it is possible to provide a sufficiently large amount of lead in the taper of each of the convex guide 31 and the notch guide 74. . Therefore, the coaxial connector 100 can easily connect the first connector and the second connector.

  In particular, the convex guide 31 formed on the insulator 30 of the first connector 100A has a very large taper formed on the circular outer periphery, and even if the cylindrical piece 42b of the second connector is made small, The connection between the first connector 100A and the second connector 100B is easy. Therefore, in the coaxial connector 100, the first connector 100A and the second connector 100B are connected by reducing the cylindrical piece 42b and lowering the lock position of the first lock claw 15 and the second lock claw 43. The height dimension when doing so is extremely small.

  In the coaxial connector 100, when the first connector 100 </ b> A and the second connector 100 </ b> B are connected, the convex guide 31 and the notched guide 74 are fitted, and the concave structure 32 and the vertical structure 71 of the insulator 70, The structure 72 is fitted. Therefore, when the first connector 100A and the second connector 100B are connected, the height dimension does not increase due to the formation of the convex guide 31 and the insulator 70.

  In the coaxial connector 100, the four convex guides 31 are formed by shifting the first connector 100A by an angle of 90 degrees, and the four notch guides 74 are formed by an angle of 90 degrees on the second connector 100B. Since they are formed so as to be shifted, the second connector can be connected to the first connector at four angles every 90 degrees. That is, in the coaxial connector 100, a coaxial cable (not shown) connected to the second connector 100B can be drawn in four directions every 90 degrees.

  In the coaxial connector 100, the socket 50 does not wobble because the socket 50 is fixed to the insulator 70 at both ends in the second connector 100B. Therefore, the through hole 51 and the connection portion 52 of the socket 50 are always arranged at predetermined positions with high accuracy.

  The coaxial connector 100 according to the embodiment has been described above. However, the present invention is not limited to the contents described above, and various modifications can be made in accordance with the spirit of the invention.

  For example, in the coaxial connector 100, the center pin 20 is formed on the first connector 100A and the socket 50 is formed on the second connector 100B. However, this is replaced to form the socket 50 on the first connector 100A. The center pin 20 may be formed on 100B.

  In the coaxial connector 100, the first connector 100A is formed with the four beam portions 13, the four through holes 14, and the four convex guides 31, and the second connector 100B is provided with the four cylindrical pieces 42b. The four notched guides 74 are formed, but the number of these is arbitrary, and the number of each can be increased or decreased.

  In the coaxial connector 100, the insulator of the second connector 100B is configured by two blocks of the insulator 60 and the insulator 70, but the number of blocks is arbitrary and can be increased or decreased. For example, the insulator 60 may be omitted and only the insulator 70 may be used.
