Description

  The present invention relates to a connector, and more particularly to a high frequency connector used when connecting parts for transmitting and receiving information.

  Most conventional high-frequency connectors for transmitting and receiving information are configured by connecting two types of members (see FIGS. 1 to 3). Among them, the first member 10 (see FIG. 1) includes a connection member 101 in which a through hole 102 is formed along a predetermined direction, and a hollow connection tube 103 is inserted into the through hole 102 of the connection member 101. . The connecting pipe 103 forms a screw thread 104 on the outer peripheral surface. The connecting member 101 and the connecting pipe 103 are connected by welding around the connecting portion, or closely fitted and positioned.

The second member 20 (see FIG. 2) also includes a connection member 202 having a through-hole 202 formed in a predetermined direction, and a hollow connection tube 203 is inserted into the through-hole 202 from one end. The connecting member 202 and the connecting pipe 203 are also connected by welding around the connecting portion, or closely fitted and positioned.

When connecting the first member 10 and the second member 20 described above (see FIGS. 3 and 3A), the ring formed between the connecting portions 204 formed by extending the C-ring 205 of the second member 20. Fit into the groove 2041. Further, the projecting pin 260 of the second member 20 is connected to the pin 105 of the first member 10 provided corresponding to the pin 206. The pin 105 has a concave groove at one end corresponding to the pin 206. Furthermore, the insulators inside the first member 10 and the second member 20 come into contact with each other.

When the first member 10 and the second member 20 described above are connected to transmit and receive information, the pins (105, 206) are in contact with each other. Therefore, when the line contacts of both members are twisted by receiving a force from the outside, they are interrupted or connected, and noise interference easily occurs.

As for the first member 10 and the second member 20, the corresponding 105 of the first member 10 is inserted into the recessed groove, and the insulators 106 inside the two connectors 10 and 20 are in contact with each other.

However, when the two connectors 10 and 20 are brought into contact with each other to transmit and receive information, the pins 105 and 206 of the two connectors are in contact with each other, so that the contact between the lines of both members is easily cut when bent by an external force. And noise is generated.

Further, since the C-ring that is fitted when the first member 10 and the second member 20 are connected is a planar member, the material is fatigued and the elasticity is attenuated when used for a certain period of time. For this reason, the contact between the first member 10 and the second member 20 is easily loosened and cannot withstand a relatively strong torque value.

  The present invention is a high-frequency connector configured by connecting a first member and a second member, and the connection between the two members does not loosen even if torsion occurs due to an external force. It is an object of the present invention to provide a high-frequency connector in which noise interference due to poor contact does not occur in line contacts.

  The high-frequency connector according to the present invention does not loosen the connection between both members constituting the connector even when torsion occurs due to external force, and noise interference due to poor contact occurs in the line contacts of both members. In addition, there is an advantage that the usage mode can be selectively changed according to the usage situation.

  The high-frequency connector according to the present invention includes a first member 4 and a second member 9 as disclosed in FIGS.

  The first member 4 (see FIGS. 4 and 5) is constituted by the connecting member 1 and the joint portion 2. A through hole 11 is formed in the connection member 1, and an insulator 41 is inserted into the through hole 11. Further, the notch 12 is formed on the side surface of the connecting member 1. By forming the notch 12, it is possible to adjust and lengthen the length of connection between the connecting member 1 and the joint 2. Further, the L-shaped pin 3 is inserted into the through hole 411 formed in the insulator 41. The L-shaped pin 3 bent at 90 ° is provided so that one end is inserted into the insulator 41 and the other end extends from the notch portion 12 into the horizontal portion 21 of the joint portion 2. With such a configuration, when the connection member 1 and the joint portion 2 are connected, the rotational movement of the joint portion 2 is limited.

  An insulator 41 is inserted into the connecting member 1, and a positioning insulator 42 is fitted on the upper end after the L-shaped pin 3 is inserted. Further, an insulator 43 having a through hole is inserted into the horizontal portion 21 of the joint portion 2. One end of the L-shaped pin 3 extending into the horizontal portion 21 of the joint portion 2 is inserted into the through hole of the insulator 43. The positioning insulator 24 has an effect of making impedance errors uniform.

The 1st member 4 by the above-mentioned composition is made into the form which has a plurality of pins 13 in which connecting member 1 is formed below, or has a plurality of pins 13 in which joint part 2 is formed in the horizontal direction. It is good also as a form which can be obtained. Regardless of the type, the connection member 1 and the joint portion 2 can be configured to be 90 ° by forming the cutout portion 12 on the side surface of the connection member 1. Moreover, it can also comprise so that the connection member 1 and the joint part 2 may become 180 degrees. (In the embodiment, the connection member 1 having a plurality of pins 13 formed downward will be described as an example.)

The second member 9 (see FIGS. 6 and 7) is configured by connecting the connecting member 5 and the joint portion 6. The connecting member 5 has a hole 51 in the side surface. By forming the hole 51, the length of connection between the connection member 5 and the joint portion 6 can be adjusted, and after the connection member 5 and the joint portion 6 are connected, each is restricted from rotating. can do.

The connecting member 5 has a hollow space 52, and a small hole 53 having a diameter smaller than that of the opening surface is formed at one end of the connection member 5. Further, the insulator 91 having a through hole formed in the axial direction is inserted from the opening surface at one end, and the pin 7 is inserted into the through hole of the insulator 91.

  One end of the pin 7 is an action end, and the action end extends from the small hole portion 53 of the connection member 5 to the outside of the connection member 5 and the other end is in contact with the insulator 92. The insulator 92 is provided in the joint portion 6. That is, the joint portion 6 has a hollow space formed therein, and has one end on the side of the connecting member 5 as an opening surface, and an attachment hole 61 is formed in one end surface facing the opening surface. A positioning member threaded on the inner wall of the mounting hole 61 and threaded on the outer peripheral surface is screwed into the mounting hole 61. The insulator 92 is inserted into the inside from the opening surface of the joint portion 6, and one surface contacts the positioning member 62, and one end of the pin 7 contacts the other surface.

Also, the joint 8 is coupled to the connecting member 5 on the side from which the working end of the pin 7 projects.

  Further, the connecting member 5 chamfers the inner wall at the opening end of the small hole portion 53 to form a gradient 54. By forming the gradient 54, the internal space of the portion where the small hole portion 53 of the connection member 5 is formed becomes wider, and there is more air in this space, and the insulating effect when information is transmitted / received by this air Is obtained. Further, by forming the gradient 54, when the first member 4 and the second member 9 are connected, even if the outer diameters of the pins of the two members are different, the impedance error can be made uniform.

When the joint 8 is coupled to the connection member 5 of the second member, a C ring 56 is fitted into the annular groove 55 formed in the connection member 5 as disclosed in FIGS. 7, 7A, 7B, and 7C. The C-ring 56 is formed so that the upper and lower ends serving as the working ends are curved and warped in one direction. For this reason, when connecting the joint 8 to the connecting member 5, the C-ring 56 is compressed toward the center of the annular groove 55, and a component force inward is generated. Therefore, the C ring 56 is easily guided by the positioning groove 81 formed in the joint 8 (see FIG. 7B). However, when a component force is generated that pushes the C-ring 56 outward in the outer circumferential direction of the annular groove 55 and receives an external force, the positioning groove 81 of the joint 8 efficiently removes the C-ring 56. Stop well. Therefore, it is possible to efficiently prevent a situation in which it is pulled and loosened by an external force and is released.

  The joint portion 6 that can be coupled to the connection member 5 and rotated by 90 ° may integrally form the connection end 63 and the direction change end 64 (see FIG. 6). In this case, the joint portion 6 can be easily processed.

  The insulator 91 inserted into the hollow space 52 of the connecting member 5 and through which the pin 7 penetrates is brought into contact with a semicircular pad 93 having a notch 931 formed at one end on the joint 6 side, and the pad 93 The notch portion 931 is brought into contact with one end of the pin 7, or the insulator 92 and the pad 93 are integrally formed, and the notch portion 931 is similarly brought into contact with one end of the pin 7. Providing the pad 93 has an effect of equalizing an error in impedance generated at a contact location of the pin 7 (that is, a location where an antenna line, a coaxial cable, etc. pass through the hole 51 of the connection member 5). . The size of the notch 931 of the pad 93 is adjusted according to the thickness of the antenna line and the coaxial cable to be connected.

As disclosed in FIG. 9, the high-frequency connector 30 according to the present invention is configured by connecting a first member 4 and a second member 9. The pin 7 whose one end protrudes from the second member 9 partially contacts the pin 3 embedded in the first member 4. In addition, a gap 94 is formed at a position where the first member 4 and the second member 9 are in contact with each other. When the linear contact is made via the pin 7 and the pin 3, noise occurs due to contact or interruption. Occurrence can be prevented efficiently.

The high-frequency connector configured by connecting the first member 4 and the second member 9 is provided on a substrate as disclosed in FIG. The pin 13 provided on the connecting member 1 of the first member 4 is positioned on the substrate 40 along a preset direction. With the above configuration, the high-frequency connector 30 according to the present invention can change the direction of the joint portion 6 of the second member 9 as necessary, as indicated by an arrow in FIG. It can respond flexibly.

As described above, the high-frequency connector according to the present invention is configured by connecting the first member and the second member, and has the following advantages in use.
1. The connection member constituting the first member can be lengthened by adjusting the length of connection between the connection member and the joint member by forming a notch in the side surface. In addition to restricting the rotation of the joint portion, the joint portion can be connected to 180 ° (ie, a single direction) or 90 ° as necessary, and can selectively respond to usage conditions. .
2. The first member constituting the second member is chamfered on the inner wall at the opening end of the small hole portion to form a gradient, thereby widening the internal space of the portion where the small hole portion of the connecting member is formed. There is more air in the space, and an insulating effect can be obtained when information is transmitted and received by this air. In addition, when the first member and the second member are connected by forming a gradient, even if the outer diameters of the pins of the two members are different, the impedance error can be made uniform.
3. When connecting a joint to the connecting member of the second member, a C-ring is fitted into an annular groove formed in the connecting member. The C-ring is formed so that the upper and lower ends are curved and curved in one direction. For this reason, the positioning groove of the joint can efficiently prevent the C-ring from being detached, and the situation where the joint positioning groove is pulled and loosened by an external force can be efficiently prevented.
4. The pin whose one end protrudes from the second member constituting the high frequency connector partially contacts the pin embedded in the first member 4. In addition, a gap is formed at a position where the first member 4 and the second member 9 are in contact with each other, and when contacting linearly through the respective pins 7, noise occurs due to contact or interruption. Can be efficiently prevented.
5). The joint portion that can be connected to the connection member of the second member and rotated by 90 ° can be easily processed by integrally forming the connection end and the direction change end.
6). The insulator inserted into the hollow space of the connecting member of the second member and through which the pin penetrates a semicircular pad formed with a notch at one end on the joint part side, and the notch of the pad Is brought into contact with one end of the pin, or the insulator and the pad are integrally formed, and the notch is similarly brought into contact with one end of the pin 7. Providing the pad in this way has the effect of equalizing the error in impedance generated at the pin contact location (that is, the location where the antenna wire, coaxial cable, etc. pass through the hole of the connection member). The size of the notch of the pad is adjusted according to the thickness of the antenna wire and coaxial cable to be connected.
7). The high-frequency connector of the present invention configured by connecting the first member and the second member can change the direction of the joint part of the second member as required, and flexibly responds to the actual usage situation. can do.
