Japanese Unexamined Patent Publication No. 2013-98122

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 soldered 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 the first connector 500A and the second connector 500B are connected. That is, since the second connector 500B must be rotatable 360 degrees with respect to the fixed first connector 500A, a notch is provided in the insulator 108 and the outer conductor 101, and the notches of both are separated from each other. By fitting, the height dimension when connected can be reduced, or by providing a notch in the skirt portion 109 and fitting the notch with the soldering portions 105a and 105b, when connected. The height dimension could not be reduced.

Further, in the coaxial connector 500, the longer the skirt portion 109 of the second connector 500B, the larger the so-called attraction amount, and the skirt portion 109 tends to come into contact with the edge of the upper opening of the outer conductor 101 of the first connector 500A. , It is preferable because the alignment when connecting the first connector 500A and the second connector 500B becomes easy. That is, the ease of connecting the first connector 500A and the second connector 500B is as shown in FIG. 9B, that is, the amount of attraction S of the skirt portion 109 and the taper provided on the edge of the cylindrical portion of the outer conductor 101. Although it depends on the size of the sum with the attracting amount T of the outer conductor 101, there is a limit to increasing the attracting amount T of the taper provided by utilizing the thickness of the outer conductor 101, so the skirt portion 109 is lengthened to attract. 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 soldered portions 105a and 105b of the first connector 500A interfere with each other (contact with each other). 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 amount or more 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 becomes large. There was a problem that it became large. Further, 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 is limited, and a very large amount of attraction can be secured. However, there is a problem that it is difficult to align the first connector 500A and the second connector 500B when they are connected.

The present invention has been made to solve the above-mentioned conventional problems, and as a means thereof, the coaxial connector of the present invention includes a first outer conductor, a first connector provided with a center pin or a socket, and a first connector. 2 An external conductor and a second connector having a socket or a center pin are provided, and the first outer conductor and the second outer conductor are connected, and the center pin of the first connector and the socket of the second connector are connected.

Can be connected at a street angle. That is, it is possible to connect the second connector to which the coaxial cable is connected to the first connector mounted on the board or the like from four directions.

It is preferred that the first connector comprises an insulator that secures the center pin or socket of the first connector and insulates it from the first outer conductor, the insulator having at least one convex guide. .. In this case, it is possible to increase the amount of attraction of the convex guide, and it is possible to easily connect the first connector and the second connector. That is, since the convex guide is not formed by using an outer conductor as in the conventional case, but is formed by using an insulator, there are no restrictions on the shape and dimensions, and the amount of attraction is increased. This is possible, and the first connector and the second connector can be easily connected. A recess is formed between the convex guides, and the recess can be fitted with the insulator of the second connector. Therefore, even if the insulator is provided in the second connector, the first connector And when connected to the second connector, the height dimension of the coaxial 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 by shifting them at an angle of 90 degrees, the first connector and the second connector can be connected at four angles every 90 degrees.

Center pin or socket of the first connector, is provided with attaching part I, the outer edge of the first connector insulator and, between the endogenous portion and the insulator, an opening is formed, the center pin or socket The soldered portion is preferably housed in the opening. In this case, the structure can be easily configured so that the center pin or socket and the first outer conductor do not interfere with each other.

The second connector comprises an insulator consisting of at least one block that secures the center pin or socket of the second connector and insulates it from the second outer conductor, the insulator having a notched guide. It is preferable to be done. In this case, it is possible to increase the amount of attraction of the notch-shaped guide, and it is possible to easily connect the first connector and the second connector. Further, when the first connector and the second connector are connected, the notch-shaped guide and the convex guide of the first connector are fitted. Further, the concave portion formed between the convex guides of the first connector and the insulator of the second connector are fitted. Therefore, even though the insulator of the first connector is provided with a convex guide and the second connector is provided with an insulator, the height dimension of the coaxial connector when the first connector and the second connector are connected is large. It doesn't get bigger.

It is preferable to provide four notched guides. In this case, the first connector and the second connector can be stably connected. Further, if the four notch-shaped guides are formed by shifting them at 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 on 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 on the second outer conductor. Since it is formed at or near the tip of the tubular piece, the height dimension when the first connector and the second connector are connected can be made extremely small.

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. Then, as will be described later, the integrated socket 50 and the insulator 70 are fixed to the second outer conductor 40 integrated with the insulator 60.

The second outer conductor 40 is formed with four retaining 41s by cutting and raising. The retaining 41 is for preventing the integrally molded insulator 60 from being separated from the second outer conductor 40.

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

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

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

The notch-shaped guide 74 is fitted with 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-shaped 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 (the side shown in FIG. 6B) of the insulator 70. The recess 76 is formed in a cross shape to match 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 the insulator 70, the through hole 51 and the connecting portion 52 of the socket 50 are arranged in the through hole 73 portion of the insulator 70. The socket 50 is held and fixed to the through hole 73 portion of the insulator 70, so that the positions of the through hole 51 and the connecting 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 the 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 horizontal 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. After locking the tip of the vertical structure 71 of the insulator 70 to a locking piece 45 formed by cutting out the second outer conductor 40 in advance, 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 structure can be manufactured by a manufacturing method widely used for manufacturing a coaxial connector, respectively. Briefly, it is as follows.

First, a metal plate such as phosphor bronze, which is a material for each 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, is prepared.

Next, the prepared metal plate is appropriately subjected to punching, bending, drawing, cutting, forging, etc., and the first outer conductor 10, the center pin 20, the second outer conductor 40, and the socket are appropriately applied. 50 is made. In addition, these steps are 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 each connected to the lead frame.

Next, the surfaces of the first outer conductor 10, the center pin 20, the second outer conductor 40, and the socket 50 are each plated.

Next, a mold is prepared, the first outer conductor 10 and the center pin 20 are housed inside the mold, and then resin is injected into the mold and cured to insulate the mold from a predetermined shape. Mold the body 30. Similarly, after accommodating the second outer conductor 40 inside the mold, the resin is injected into the inside of the mold and cured to form an insulator 60 having a predetermined shape. Similarly, after accommodating the socket 50 inside the mold, the 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 each 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, respectively. As a result, 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 the insulator 70 are fixed to the second outer conductor 40 integrated with the insulator 60 to complete the second connector 100B. 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 of connecting the first connector 100A and the second connector 100B will be described with reference to FIGS. 7A, 7B, and 8B. Note that 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 they are connected. FIG. 8 is a cross-sectional view of a main part which is a partially enlarged view of FIG. 7B.

First, as shown in FIG. 7A, the side on which the center pin 20 of the first connector 100A is formed and the side on which the socket 50 of the second connector 100B is formed face each other, and the first connector 100A and the first connector 100A are first. Two connectors 100B are arranged. At this time, the first connector 100A is already mounted on a board 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 brought 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 and the tubular piece 42b of the second outer conductor 40 of the second connector 100B come into contact with each other. Further, when the second connector 100B is brought closer to the first connector 100A, the tubular piece 42b of the second outer conductor 40 slides 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 match.

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 notched guides are formed. The 74 is fitted, the four recesses 32 are fitted, 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 tubular pieces 42b are inserted into the four through holes 14, the first lock claws 15 and the second lock claws 43 are engaged with each other, and the connection between the first connector 100A and the second connector 100B is completed. 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 on the inner portion 12 of the first outer conductor 10 slightly floating from the mounting surface, and the second lock claw 43 of the second connector 100B is formed. Since it is formed near the tip of the tubular piece 42b of the second outer conductor 40, 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 on the insulator 30, the notch-shaped guide 74 is formed on the insulator 70, and the coaxial connector 100 is not formed on the outer conductor unlike the skirt portion which is a conventional guide. , The shape and dimensions of the convex guide 31 and the notch guide 74 have a high degree of freedom in designing, and it is possible to provide a sufficiently large amount of attraction to 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 outer peripheral portion of the circle, and even if the tubular piece 42b of the second connector is made smaller, the first The connection between the 1st connector 100A and the 2nd connector 100B is easy. Therefore, in the coaxial connector 100, the first connector 100A and the second connector 100B are connected by making the tubular piece 42b smaller and lowering the lock position between the first lock claw 15 and the second lock claw 43. The height dimension when it is used is extremely small.

In the coaxial connector 100, when the first connector 100A and the second connector 100B are connected, the convex guide 31 and the notch-shaped guide 74 are fitted, and the recess 32 and the vertical structure 71 of the insulator 70, laterally, are fitted. Fits with the structure 72. 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, four convex guides 31 are formed on the first connector 100A by shifting them at an angle of 90 degrees, and four notched guides 74 are formed on the second connector 100B at an angle of 90 degrees. Since the connectors are staggered, the second connector can be connected to the first connector at four angles every 90 degrees. That is, in the coaxial connector 100, the coaxial cable (not shown) connected to the second connector 100B can be pulled out in four directions every 90 degrees.

In the coaxial connector 100, in the second connector 100B, since the socket 50 is held and fixed to the insulator 70, the socket 50 does not wobble. Therefore, the through hole 51 and the connecting 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 above-mentioned contents, and various modifications can be made in accordance with the gist of the invention.

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

Further, in the coaxial connector 100, four beam portions 13, four through holes 14, and four convex guides 31 are formed in the first connector 100A, and four tubular pieces 42b are formed in the second connector 100B. And four notched guides 74 were formed, the number of which is arbitrary, and the number of each can be increased or decreased.

Further, in the coaxial connector 100, the insulator of the second connector 100B is composed of two blocks, 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.
