And an insulator 601 formed between the second terminal 500 and the like. The coaxial connector 100 can be mounted on a board, and is connected to the board through a board connecting part 401 of the first terminal 400 or a board connecting part 501 of the second terminal 500 exposed to the outside, thereby providing a substrate. It can form part of a circuit.

The coaxial connector 100 according to the present embodiment is used in portable information communication devices such as mobile phones, smart phones, notebook personal computers, tablet personal computers, and the like for characteristic tests, inspections, etc. of high frequency circuits and antennas incorporated therein. . Moreover, the external conductor 300 is shielded for the high frequency circuit, and the impedance matching of the 1st terminal 400 and the 2nd terminal 500 is performed.

Moreover, the intaglio recessed part 202 is formed in the upper surface of the insulated housing 200, and the center conductor 701a, 701b of the coaxial plug 700a, 700b is formed from the upper part in the center of the bottom surface of this recessed part 202 from upper direction. An acceptable vertical hole 203 is formed. Moreover, below this vertical hole 203, the horizontally long space 204 which communicates with this vertical hole 203 is formed, and when coaxial plug 700a, 700b is attached, the center conductor 701a, 701b of The tip portion passes through the vertical hole 203 to reach the space 204. In addition, the insulating housing 200 can be divided into two component parts, for example, and it is set as the structure suitable for assembling the 1st terminal 400, the 2nd terminal 500, etc.

The outer conductor 300 is formed by punching and bending a conductive material such as a metal plate, for example. On the upper surface of the outer conductor 300, a cylindrical upper portion 301 is formed. When the coaxial plug is inserted, the lower ends of the outer conductors 702a and 702b on the coaxial plug side abut the upper portion 301 so as to be electrically connected to the outer conductor 300 of the coaxial connector 100. The outer circumferential surface of the upper portion 301 of the outer conductor 300 is formed with a semicircular cross-sectional annular groove 302, and at the time of insertion of another type of coaxial plug (not shown), the outer conductor 702a on the coaxial plug side. 702b is fitted to the annular groove 302.

4 is a perspective view illustrating a configuration example of the first terminal 400. The first terminal 400 is formed by punching and bending a metal plate of a conductive material, such as beryllium copper, phosphorus copper, ternary copper, and Coulson copper, for example. The first terminal 400 includes a plate-shaped fixing portion 403, an extension portion 404 extending from the fixing portion 403 toward the center of the insulating housing 200, and a proximal end of the fixing portion 403. It has a board | substrate connection part 401 formed in the edge part bent downward in c-shape, the arm part 405, etc. between them. The extension portion 404 has a circular hole 407 having a diameter smaller than that of the longitudinal hole 203, just below the longitudinal hole 203, to allow the thin center conductor 701b of the coaxial plug 700b to escape. It is supposed to be. Wedge-shaped protrusions 406 are formed on the side of the fixing portion 403, and the fixing portions 403 are inserted through the insertion holes of the insulating housing 200 from the side of the insulating housing 200 through these protrusions 406. The space 204 is press-fitted in a horizontal position. As a result, the fixing part 403 is provided inside the insulating housing 200, and the arm part 405 and the board | substrate connection part 401 other than that are in the state exposed to the exterior of the insulating housing 200. .

It is sectional drawing which shows the coaxial connector by other embodiment of this invention. As for the coaxial connector 100a shown in FIG. 5, the extension part 404a of the 1st terminal 400a protrudes a little upwards and is elastically deformable, The center conductor of the coaxial plugs 700a and 700b by the elastic force is performed. The contact reliability with 701a, 701b can be improved. Moreover, since the extension part 404a is pressed down at the time of contact with center conductor 701a, 701b, the contact part 402a of the 1st terminal 400a and the contact part 504 of the 2nd terminal 500 rub, and therefore, a contact part ( The cleaning effect of 402a, 504 is obtained. In addition, since the insulating housing can be divided into two component parts, for example, it is preferable to assemble an elastic piece extending upward, such as the extension part 404a.

6 is a perspective view illustrating a configuration example of the second terminal 500. The second terminal 500 is formed by punching and bending a metal plate made of a conductive material, such as beryllium copper, phosphorus copper, ternary copper, and Colson copper, for example. The second terminal 500 is formed from the plate-shaped fixing portion 502 and the substrate connecting portion 501 (see FIG. 2) formed by bending U-shaped downward from the base end side of the fixing portion 502 and the fixing portion 502. The elastic part 503 extended to cantilever compensation is provided in the upper direction inclined in the front-end direction. The contact portion (second contact portion) 509 substantially at the center of the elastic portion 503 is able to contact the thin center conductor 701b of the coaxial plug 700b, and the contact portion (fourth) is closer to the tip side than the contact position. Contact portion 504, and the contact portion 504 is capable of contacting the lower end of the contact portion (third contact portion) 402 of the first terminal 400. Wedge-shaped projections 505 are formed on the side of the fixing portion 502, and the fixing portion 502 is formed in the space of the insulating housing 200 from the opposite side of the press-in direction of the first terminal 400 via the projection 505. 204 is pressed into the horizontal position. Both outer peripheral portions 506 of the elastic portion 503 extend in width from the vicinity of the contact position toward the fixing portion 502 of the second terminal 500 and form a concave curved shape. In addition, the cutout portion 507 is formed in the elastic portion 503 toward the fixed portion 502 at abutting position, and the cutout portion 507 extends along the elastic portion 503. Moreover, the granular piece 508 is formed in the fixing | fixed part 502, and the granular piece 508 prevents the intrusion of the foreign material from the side insertion hole.

The outer edge of the coaxial plug 700a is a position away from the position where the distal end portion of the thin center conductor 701b of the coaxial plug 700b abuts (near the center of the vertical hole 203) on the upper surface of the second terminal 500. Insulation film (resist) is applied to two parallel grooves so that a portion of the tip portion of the central conductor 701a having the portion abuts so as to be orthogonal to the extension protruding direction of the elastic portion 503, so that two insulators 601a and 601b are provided. To form. In addition, the insulator 601b close to the first terminal 400 is formed short so as to avoid interference with the first terminal 400. As a result, the contact between the third contact portion 402 and the fourth contact portion 504 is not prevented when the coaxial plug is not inserted. The insulators 601 and 602 may be formed by integral molding of a resin or the like instead of covering the insulator. Instead of covering the insulator, the insulators 601 and 602 may oxidize the surface of the second terminal 500 by laser irradiation or the like to form an oxide film.

As shown in FIG. 7, various shapes can be taken as the form of the insulator 601. For example, as shown in Fig. 7A, an insulating coating may be applied to the upper surface of the second terminal 500a to form a donut-like insulator 601c. In addition, as shown in Fig. 7 (b), a resin may be integrally molded on the upper surface of the second terminal 500b to form a cylindrical insulator 601d.

FIG. 8 is a view showing a state in which a coaxial plug 700a having an outer edge portion 705 is fitted to the coaxial connector 100. FIG. 8 (a) is an overall view and FIG. 8 (b) is a coaxial connector 100. It is an enlarged sectional view of neighborhood. FIG. 9 is a view showing a state in which a coaxial plug 700b having no outer edge is fitted to the coaxial connector 100. FIG. 9 (a) is an overall view and FIG. 9 (b) is an enlargement near the coaxial connector 100. FIG. It is a cross section. For the inspection, a coaxial plug having at least two types of tip ends is used. In addition, in this specification, the "tip part" of a center conductor is an edge part of the axial direction of a center conductor, and means the part inserted in the longitudinal hole of a coaxial connector. In addition, the "tip part" of a center conductor means the part which contacts a 2nd terminal as a part of "tip part." In addition, an "outer edge part" means a ring-shaped part formed around the "tip part" as a part of the "tip part".

In order to measure characteristics such as an antenna, when the first terminal 400 and the second terminal 500 are electrically disconnected and the center conductor of the first terminal 400 and the coaxial plug are electrically connected, A first coaxial plug 700a having a large tip having a large diameter is used. As shown in Fig. 8 (b), the tip portion of the coaxial plug 700a has a projection 703 which is annular and cross-sectional stepped projecting downward from the lower end position of the outer edge portion 705, and the projection 703 On the inner side, a cylindrical recess 704 is formed to be cut to the same position as the lower surface of the first terminal. The protrusion 703 is formed at a position exiting the hole 407 of the first terminal 400. The diameter of the outer circumferential portion of the protrusion 703 is larger than the diameter of the hole 407. ). The projection 703 is in contact with the insulators 601a and 601b on the second terminal 500. Since the inner center portion of the projection 703 is a recess 704 or the thickness of the insulator, the center conductor 701a is not in contact with the contact portion 509 of the second terminal 500. It is. When the coaxial plug 700a is inserted, the center conductor 701a is in contact with the contact portion 408 of the first terminal 400. In addition, since there is a concave portion 704, isolation from the second terminal 500 is reduced. In the coaxial plug, the outer conductors 702a and 702b are elastically supported so as to be displaceable in the vertical direction together with the plug insulator with respect to the main body of the plug, and the center conductor is also elastically supported so as to be independently changeable.

In order to measure the characteristics of a high frequency circuit etc., when the 1st terminal 400 and the 2nd terminal 500 are electrically cut off, and the 2nd terminal 500 and the center conductor of a coaxial plug are electrically connected, it is a center conductor. A second coaxial plug 700b having a diameter smaller than the first coaxial plug 700a is used. The diameter of the tip portion of the center conductor 701b of the second coaxial plug 700b is smaller than the hole 407 of the first terminal 400 to exit the hole 407. The distal end portion of the center conductor 701b is in contact with the contact portion 509 of the second terminal 500. In addition, the connection relationship between an antenna and a high frequency circuit may be reversed.

When the coaxial plugs 700a and 700b are not mounted, the contact portion (fourth contact portion) 504 of the second terminal 500 is the contact portion (third portion) of the first terminal 400 by the elastic force of the elastic portion 503. Contact portion 402, the first terminal 400 and the second terminal 500 are maintained in an electrically connected state.

When the first coaxial plug 700a having the outer edge portion 705 is mounted, the lower end portion of the outer conductor 702a of the first coaxial plug 700a abuts on the outer conductor 300, and the center conductor of the coaxial plug ( The tip end of 701a is inserted through the longitudinal hole 203. In this state, the projection 703 of the tip portion of the central conductor 701a of the coaxial plug 700a abuts on the insulator 601 of the elastic portion 503. At this time, since the elastic force of the center conductor of the coaxial plug is stronger than that of the elastic portion 503, the elastic portion 503 is pressed down by the center conductor of the coaxial plug and elastically deformed, and the contact portion 504 is separated from the contact portion 402. Thus, the first terminal 400 and the second terminal 500 are electrically separated. At the same time, the outer edge portion 705 of the tip portion of the center conductor of the coaxial plug is connected to the contact portion (first contact portion) 408 of the outer edge of the hole 407 of the extension portion 404 of the first terminal 400. It comes in contact with the center conductor of the coaxial plug, and the 1st terminal 400 is connected. Thereby, the signal which flowed from the 1st terminal 400 to the 2nd terminal 500 flows from the 1st terminal 400 to the center conductor of a coaxial plug, and it becomes possible to test an antenna.

The positional relationship between the second contact portion 509, the fourth contact portion 504, and the insulator 601 is a preferable positional relationship for breaking the connection between the third contact portion 402 and the fourth contact portion 504. That is, since there is a fourth contact portion 504 on the free end side of the second terminal 500 of the cantilevered portion, and the insulator 601 abuts on the base side rather than the contact portion position, the fourth contact portion is on the free end side than the displacement amount of the contacted portion. The displacement amount of 504 becomes large.

When the second coaxial plug 700b having a central conductor having a small diameter at the tip end is mounted, the lower end portion of the outer conductor 702b of the second coaxial plug 700b abuts on the outer conductor 300 and the center of the coaxial plug The tip end of the conductor 702b is inserted through the longitudinal hole 203. In this state, the center conductor 702b of the coaxial plug abuts on the contact portion (second contact portion) 509 of the elastic portion 503. At this time, since the elastic force of the center conductor of the coaxial plug is stronger than that of the elastic portion 503, the elastic portion 503 is pressed down by the center conductor of the coaxial plug and elastically deformed, and the contact portion 504 is separated from the contact portion 402. As a result, the first terminal 400 and the second terminal 500 are electrically separated, and the center conductor of the coaxial plug and the second terminal 500 are connected to each other. Thereby, the signal which flowed from the 2nd terminal 500 to the 1st terminal 400 flows from the 2nd terminal 500 to the center conductor of a coaxial plug, and it becomes possible to test a high frequency circuit.

FIG. 10 is a perspective view showing a structure in which an insulator 601 is formed on both the lower surface of the first terminal 400 and the upper surface of the second terminal 500 of the coaxial connector according to another embodiment of the present invention. ) Is a configuration of the second terminal 500c, and FIG. 10 (b) is a diagram in which the first terminal 400b and the second terminal 500c are combined. As shown in FIG. 10, even if the insulator 601 is formed in both the lower surface of the 1st terminal 400 and the upper surface of the 2nd terminal 500, the same effect can be acquired. In this case, since the 1st terminal 400b is pressed down by the large diameter conductor, the insulator 601e, 601f of the lower surface of the 1st terminal 400b, and the insulator 601g, 601h of the upper surface of the terminal 500c will be The second terminal 500c is also pressed down to cut off the contact between the first terminal 400b and the second terminal 500c. That is, even in the center conductor without the projection 703 as shown in FIG. 8, the first terminal 400b and the second terminal 500c are not pressed down by the center conductors 701a and 701b. Can cut off the electrical connection.

FIG. 11: is a perspective view which shows the structure in which the insulator 601 was formed in the lower surface of the 1st terminal 400 of the coaxial connector which concerns on other embodiment of this invention. As shown in FIG. 11, you may form insulators 601e and 601f in the lower surface of the terminal 400b. In this case, when the first terminal 400b is pressed down by a large diameter conductor, the second terminal 500 is also pressed down by the action of the insulators 601e and 601f, so that the first terminal 400b and the second terminal ( 500) can be blocked. That is, even in the center conductor without the projection 703 as shown in FIG. 8, the first terminal 400b and the second terminal 500 are not pressed down by the center conductors 701a and 701b directly. ) Can cut off the electrical connection.

FIG. 12 is a perspective view illustrating another configuration example of the first terminal similarly to FIG. 5. The 1st terminal 400c shown in FIG. 12 is equipped with the 1st contact part 408c elastically deformed by the shape cut out and formed in the part which the outer edge part of the center conductor of a coaxial plug abuts around the hole. Thus, when the coaxial plug is fitted, the entire extension portion 404c of the terminal 400c does not elastically deform like the elastic portion 404a of FIG. 5, but only the contact portion 408c elastically deforms.

13 and 14 are views showing a state where a coaxial plug is fitted to a coaxial connector according to another embodiment of the present invention, in which FIG. 13 (a) is an overall view and FIG. 13 (b) is near the coaxial connector 100b. It is an enlarged cross section. The coaxial connector 100b shown to FIG. 13 and FIG. 14 is equipped with the insulator 601k in the position of the 2nd contact part 509 of the 2nd terminal 500. As shown in FIG. Moreover, as shown in FIG. 13, in the small coaxial plug 701c, the recessed part 704c is formed in the center of the front-end | tip part (part to which the insulator 601k abuts), and the processus | protrusion 703c is formed in the periphery. It is. As shown in Fig. 14, a large diameter coaxial plug 701d is formed with a projection 703d at the center of the tip portion (a portion where the insulator 601k abuts), and an outer edge portion 705d is formed around the coaxial plug 701d. It is. Thus, by forming the outer edge part 705d in the coaxial plug 701d, and omitting the outer edge part from the coaxial plug 701c, the same effect as the said embodiment can be acquired.

Fig. 15 is a sectional view showing a coaxial connector according to another embodiment of the present invention, in which Fig. 15 (a) shows only a coaxial connector, and Fig. 15 (b) shows a coaxial plug fitted into a coaxial connector and the center conductor is inserted into a hole of the coaxial connector. 15 (c) shows a state in which the coaxial plug is fitted to the coaxial connector and the center conductor is inserted into the hole of the coaxial connector. The coaxial connector 100d shown in FIG. 15 does not have the insulator 601. Instead, the insulator 601l is provided on the coaxial plug 700e side. The insulator 601l is formed in the front-end | tip part of the center conductor 701e of the coaxial plug 700e, and the outer edge part 705e is formed in the periphery. As a result, when the distal end portion of the center conductor 701e of the coaxial plug 700e is inserted into the hole of the coaxial connector 100d, the second terminal 500d is pressed down by the insulator 601l, and the first terminal 400d and Electrical connection of the second terminal 500d is cut off, and the outer edge portion 705e of the center conductor 701e abuts on the first terminal 400d and is electrically connected. By such a configuration, the same effects as in the above embodiment can be obtained.

In addition, although not shown in particular, the state which floats between the 1st terminal 400 and the 2nd terminal 500, without forming the insulator 601 in the surface of the 1st terminal 400 or the 2nd terminal 500 is shown. You may arrange as. Moreover, you may arrange | position in the movable state in the hole 407 of the 1st terminal 400, without fixing the insulator 601d of FIG. 7 (b) to the surface of the 2nd terminal 500b. In this case, when the coaxial plug is not fitted, that is, when the first terminal 400 and the second terminal 500 are in contact with each other, the upper surface of the cylindrical insulator 601d is larger than the upper surface of the first terminal 400. When configured to protrude upward, when the tip portion is fitted with a flat thick center conductor, the insulator 601d is pressed down to cut off the connection between the first terminal 400 and the second terminal 500, and the outer edge of the thick center conductor The part 705 abuts on the first terminal 400 and is electrically connected thereto. In this specification, "in between the 1st terminal 400 and the 2nd terminal 500" should just be a part of insulator. For example, in the case of a floating insulator, a part of the insulator protrudes above the surface of the first terminal 400.

Therefore, according to the coaxial connector of the said embodiment, switching of multiple terminals is attained with the structure of high productivity and low cost. Moreover, there is no restriction | limiting of the rotation angle at the time of insertion, and operability can be made favorable. Furthermore, by apply | coating an insulating film (resist), it can be made high in production efficiency. Moreover, by apply | coating an insulating film, it is very effective to the structure which is very restrictive in a height direction. In addition, the gap is blocked by the insulator and foreign matter hardly enters.

Is an exploded perspective view of the. First, the structure of the coaxial connector which concerns on this embodiment is demonstrated with FIGS. 16-19. The coaxial connector 1000 according to the present embodiment is a coaxial connector with a switch mounted on a board, and the center conductors 7010a and 7010b of the coaxial plugs 7000a and 7000b (see FIGS. 31 and 32, etc.) are upwards. An insulating housing 2000 having a longitudinal hole 2030 that can be accommodated (the insulating housing 2000 is composed of an upper insulating housing 2000a and a lower insulating housing 2000b) and an outer side of the insulating housing 2000. Formed, the outer conductor 3000 to which the outer conductors 7020a and 7020b of the coaxial plugs 7000a and 7000b can be attached and detached, a connecting plate 4000 formed below the longitudinal hole 2030, and the longitudinal hole 2030. ) Is further composed of a switching spring (5000) formed below the connecting plate (4000), an insulator (6010) formed integrally with both sides of the switching spring (5000), and the like. The coaxial connector 1000 is mountable on the board, and is connected to the circuit of the board through the board connecting portion 4010 of the connecting plate 4000 and the board connecting portion 5010 of the switching spring 5000 which are exposed to the outside, A portion of the substrate circuit can be formed.

The coaxial connector 1000 according to the present embodiment is a portable information communication device such as a cellular phone, a smart phone, a notebook personal computer, a tablet personal computer, and includes a characteristic test, an inspection, and the like for a built-in high frequency circuit and an antenna. Used. In addition, for the high frequency circuit, the external conductor 3000 is shielded, and the connection plate 4000 and the switching spring 5000 have impedance matching.

The insulating housing 2000 is formed of insulating resin such as plastic. The main body part of the insulating housing 2000 has a substantially rectangular parallelepiped shape, and the upper part of the substantially center is cylindrical. In addition, the upper surface of the insulating housing 2000 is formed with a concave concave portion 2020, and the center conductors 7010a and 7010b of the coaxial plugs 7000a and 7000b are formed at the center of the bottom surface of the concave portion 2020. The vertical hole 2030 that can be accommodated from above is perforated. Moreover, below this vertical hole 2030, when the horizontally long space 2040 which communicates with this vertical hole 2030 is formed, and the coaxial plug 7000a, 7000b is attached, the center conductor 7010a, 7010b will be provided. The tip of the tube passes through the vertical hole 2030 to reach the space 2040. In addition, the insulating housing 2000 can be divided into, for example, two component parts (upper insulating housing 2000a and lower insulating housing 2000b) to mount the connecting plate 4000, the switching spring 5000, and the like. It is in a preferred configuration.

The outer conductor 3000 is formed by punching and bending a conductive material such as a metal plate, for example. On the upper surface of the outer conductor 3000, a cylindrical upper portion 3010 is formed. When the coaxial plug is inserted, the lower ends of the outer conductors 7020a and 7020b on the coaxial plug side abut the upper portion 3010 so as to be electrically connected to the outer conductor 3000 of the coaxial connector 1000. The outer circumferential surface of the upper portion 3010 of the outer conductor 3000 is formed with an annular groove 3020 having a semicircular cross section, and the outer conductor 7020a on the coaxial plug side when inserting another type of coaxial plug (not shown). , The lower end of 7020b is fitted to this annular groove 3020.

The connecting plate 4000 is formed by punching and bending a metal plate of a conductive material such as beryllium copper, phosphor bronze, tri-element copper, or Corson copper, for example. The connecting plate 4000 includes a plate-shaped fixing portion 4030, an elastically deformable extension portion 4040 extending inclined upward from the fixing portion 4030 toward the center of the insulating housing 2000, and the fixing portion ( The board | substrate connection part 4010 etc. which were formed in the edge part bent downward from the base end side of 4030 were formed. The extension portion 4040 has a circular hole 4070 having a diameter smaller than that of the longitudinal hole 2030, just below the longitudinal hole 2030, and the thin center conductor 7010b of the coaxial plug 7000b is missing. I am going to go out. The fixing part 4030 is integrally molded in the horizontal position in the space 2040 of the insulating housing 2000 from the side of the insulating housing 2000. As a result, the fixing part 4030 is fixed to the inside of the insulating housing 2000, and the board | substrate connection part 4010 will be in the state exposed to the exterior of the insulating housing 2000. As shown in FIG. In addition, a rough contact portion (third contact portion) 4020 is formed in a substantially middle portion between the fixed portion 4030 and the extension portion 4040, and faces downward from the upper portion, and the contact portion (fourth contact portion) of the switching spring 5000 is provided. Although 5040 is slightly contacted so as to slide, the contact reliability can be improved. In addition, the tip part of the connecting plate 4000 has a bifurcated structure, and is multi-contact.

In addition, the extension portion 4040 of the connecting plate 4000 is able to spring upward and be elastically deformed, so that the contact reliability with the center conductor 7010a of the coaxial plug 7000a can be improved by the elastic force. It is. In addition, since the extension part 4040 is pressed down at the time of contact with the center conductor 7010a, the contact part 4020 of the connection plate 4000 and the contact part 5040 of the switching spring 5000 are in contact so that it may slide, The wiping (cleaning) effect of the contacts 4020 and 5040 is further obtained. In addition, since the insulating housing 2000 can be divided | segmented into two component parts 2000a, 2000b, for example, the elastic piece extended upward like the elastic part 5030 of the switching spring 5000 mentioned later is attached. Preferred below.

20 is a perspective view showing a configuration example (finished product) of the switching spring 5000 in which the insulator 6010 is integrally formed, and FIG. 20 (a) is a view seen from above and FIG. 20 (b) is a view seen from below. to be. FIG. 21: is a perspective view which shows the structural example (terminal only) of the switching spring 5000 before the insulator 6010 is integrally formed, FIG.21 (a) is the figure seen from the upper side, FIG.21 (b) is the lower side This is the figure.

The switching spring 5000 is formed by punching and bending a metal plate of a conductive material such as beryllium copper, phosphor bronze, tri-element copper, or Corson copper. The switching spring 5000 has a flat plate-shaped fixed portion 5020, a substrate connecting portion 5010 formed bent downward from the base end side of the fixed portion 5020, and a cantilever beam shape from the fixed portion 5020 upwardly inclined upward. It is provided with an elastic portion 5030 extending. The contact portion (second contact portion) 5090 substantially at the center of the elastic portion 5030 can abut the thin center conductor 7010b of the coaxial plug 7000b, and is divided into two branches at the tip side than the abutting position. It has two contact parts (fourth contact part) 5040, and the two contact parts 5040 are each able to contact the lower end of two contact parts (third contact part) 4020 of the connection plate 4000, respectively. .

The upper surface of the switching spring 5000 is a position deviated from the position where the distal end of the thin center conductor 7010b of the coaxial plug 7000b abuts (near the center of the vertical hole 2030), and thus the The insulator 6010 (upper part 6010a, 6010b) is formed in the part which the front-end | tip part of the center conductor 7010a which has an outer edge part abuts. In addition, the insulator 6010 has two holes of the switching spring 5000. The upper portions 6010a and 6010b and the lower portion 6010c are connected via 5110a and 5110b (see Fig. 21), and the upper portion 6010a and the upper portion 6010b of the insulator 6010. Are separated and connected to the lower surface of the switching spring 5000 by the lower portion 6010c. The insulator 6010 having a larger area than the holes 5110a and 5110b is integrally formed on the upper and lower surfaces of the switching spring 5000. By forming and sandwiching it, Since the insulator 6010 is fixed to the switching spring 5000 in a state of being engaged in the thickness direction (the direction in which the tip end of the center conductor 7010b abuts and is pressed), the insulator 6010 is firmly fixed to the switching spring 5000. This prevents the insulator 6010 from peeling off well from the switching spring 5000. Further, the connection portion 5120 between the hole 5110a and the hole 5110b under the switching spring 5000 is thinned one step. When the resin is integrally molded, the fluidity of the mold is improved, and the thickness of the mold can be sufficiently secured.In addition, the insulator 6010b close to the connection plate 4000 includes a connection plate 4000; The inclination 6010d is formed so as to avoid the interference of the wires, thereby preventing the contact between the third contact portion 4020 and the fourth contact portion 5040 when the coaxial plug is not inserted. The structure in which the two insulators 6010a and 6010b are connected to each other prevents plastic deformation of the spring by strengthening the fixing strength and filling the back surface of the point pressed by the center conductor of the coaxial plug with resin. It works.

FIG. 25 is a perspective view showing a second modification example (terminal only) of the switching spring 5000 before the insulator 6010 is integrally formed. As shown in FIGS. 24 and 25, cutouts 5130 are formed on both sides of the switching spring 5000, and the strip-shaped insulators 6010 are integrally formed by sandwiching the cutouts 5130 therebetween. It may be.

FIG. 27: is a perspective view which shows the 3rd modification (terminal only) of the switching spring 5000 before the insulator 6010 is integrally formed. As shown to FIG. 26 and FIG. 27, the hole 5140 is formed in the contact part 5090 part of the elastic part 5030 of the switching spring 5000, and through the hole 5140 of the switching spring 5000, The insulator 6010 may be integrally formed on the upper and lower surfaces. Moreover, peeling of the insulator 6010 is prevented by making the diameter of the insulator 6010 larger than the diameter of the hole 5140. In the third modification, a recess (concave) is formed in a portion of the coaxial plug 7000b that is in contact with the insulator 6010 as a central portion of the tip portion of the thin center conductor 7010b, and the tip portion of the center conductor 7010b is formed. The periphery of the is normally projected to avoid interference with the insulator 6010 when coaxial plug fitting, so that only the periphery is in contact with the switching spring 5000. Moreover, as a center part of the front-end | tip part of the thick center conductor 7010a of the coaxial plug 7000a, a processus | protrusion (convex part) is formed in the part which contacts the insulator 6010, and it switches by the processus at the time of coaxial plug fitting. The spring 5000 is pressed down so that only the peripheral portion of the center conductor 7010a is in contact with the connecting plate 4000.

FIG. 28: is a perspective view which shows the modification of the connection plate 4000, (a) is the figure seen from the upper side, (b) is the figure seen from the lower side. As shown in FIG. 28, the contact part 4080 of the periphery of the hole 4070 may be made into the shape which protruded from the lower surface side and protruded to the upper surface side. At this time, the inclined portion is formed on the upper surface of the projection to form the edge portion, whereby foreign matter such as dust can be prevented from adhering to the surface.

FIG. 29: is a perspective view which shows the structure which combined the lower insulation housing 2000b and the switching spring 5000. FIG. These may be constituted by assembling constituent parts, or may be formed by integral molding (molding) by pouring a resin or the like into a mold. FIG. 30 is a perspective view showing a configuration in which the upper insulating housing 2000a, the connecting plate 4000, and the outer conductor 3000 are combined, and is in an inverted state. These may be constituted by assembling constituent parts, or may be formed by integral molding (molding) by pouring a resin or the like into a mold. The coaxial connector 1000 according to the present embodiment is assembled by inverting the configuration of FIG. 30, covering the configuration of FIG. 29, and caulking both sides of the outer conductor 3000. In addition, since the support part 2060 of the lower side insulating housing 2000b has the structure which can interfere with the both edges of the extension part 4040 of the connection plate 4000, when the coaxial plug fitting is carried out, Even if pressed down by a strong force, the support part 2060 is restrict | limited the downward movement of the connection plate 4000 more than predetermined.

FIG. 31: is a figure which shows the state which fitted the coaxial plug 7000a which has the outer edge part 7050 to the coaxial connector 1000, (a) is a whole view, (b) enlarges the vicinity of the coaxial connector 1000. As shown in FIG. It is a cross section. FIG. 32: is a figure which shows the state which fitted the coaxial plug 7000b which does not have an outer edge part to the coaxial connector 1000, (a) is a whole view, (b) is an expanded sectional view of the vicinity of the coaxial connector 1000. As shown in FIG.

For the inspection, coaxial plugs having at least 17 types of tip are used. In addition, in this specification, the "tip part" of a center conductor is the edge part of the axial direction of a center conductor, and means the part inserted in the longitudinal hole of a coaxial connector. In addition, the "tip part" of a center conductor means a part which contacts a switching spring as a part of "tip part." In addition, an "outer edge part" is a part of a "tip part", and means the annular part formed around the "tip part" and extending in the radial direction of a center conductor.

In order to measure characteristics such as an antenna, the connecting plate 4000 and the switching spring 5000 are electrically disconnected, and when the connecting plate 4000 and the center conductor of the coaxial plug are electrically connected, the tip end of the center conductor is large. A first coaxial plug 7000a having a diameter is used. As shown in FIG.31 (b), the front-end | tip part of the coaxial plug 7000a has the projection 7030 of the cross-sectional step shape which protrudes downward from the lower end position of the outer edge part 7050. Although the protrusion 7030 is formed in the position which passes through the hole 4070 of the connection plate 4000, the diameter of the outer peripheral part of the protrusion 7030 becomes larger than the diameter of the hole 4070, and the outer edge part 7050 ). The projection 7030 is in contact with the insulators 6010a and 6010b on the switching spring 5000. By having the thickness of an insulator, the center conductor 7010a has a structure which does not contact the contact part 5090 of the switching spring 5000. As shown in FIG. In addition, when the coaxial plug 7000a is inserted, the outer edge portion 7050 of the center conductor 7010a is in contact with the contact portion 4080 of the connecting plate 4000. In addition, the coaxial plug is elastically supported so that the outer conductors 7020a and 7020b can be displaced in the up and down direction with the plug insulator with respect to the main body of the plug, and is also elastically supported so that the center conductor can also be independently changed.

In order to measure characteristics of a high frequency circuit or the like, when the connecting plate 4000 and the switching spring 5000 are electrically disconnected and the center conductor of the switching spring 5000 and the coaxial plug are electrically connected, the tip portion of the center conductor A second coaxial plug 7000b having a diameter smaller than the first coaxial plug 7000a is used. The diameter of the distal end of the center conductor 7010b of the second coaxial plug 7000b is smaller than the hole 4070 of the connecting plate 4000 so as to exit the hole 4070. The tip of the center conductor 7010b is in contact with the contact portion 5090 of the switching spring 5000. In addition, the connection relationship between an antenna and a high frequency circuit may be reversed.

When the coaxial plugs 7000a and 7000b are not mounted, the contact portion (fourth contact portion) 5040 of the switching spring 5000 is the contact portion (third portion) of the connecting plate 4000 by the elastic force of the elastic portion 5030. Contact portion 4020, the connecting plate 4000 and the switching spring 5000 maintain the electrically connected state.

When the first coaxial plug 7000a having the outer edge 7050 is mounted, the lower end portion of the outer conductor 7020a of the first coaxial plug 7000a abuts on the outer conductor 3000, and the center conductor of the coaxial plug The distal end portion of the 7010a is inserted into the vertical hole 2030. In this state, the projection 7030 of the tip portion of the central conductor 7010a of the coaxial plug 7000a abuts on the insulator 6010 of the elastic portion 5030. At this time, since the elastic force of the center conductor of the coaxial plug is stronger than the elastic portion 5030, the elastic portion 5030 is pushed down by the center conductor of the coaxial plug and elastically deformed, and the contact portion 5040 is separated from the contact portion 4020. The separation plate 4000 and the switching spring 5000 are electrically separated from each other. At the same time, the outer edge portion 7050 of the tip portion of the center conductor of the coaxial plug is the contact portion (first contact portion) 4080 of the outer edge of the hole 4070 of the extension portion 4040 of the connecting plate 4000. In contact with each other, the center conductor of the coaxial plug and the connecting plate 4000 are connected. Thereby, the signal which flowed from the connecting plate 4000 to the switching spring 5000 flows from the connecting plate 4000 to the center conductor of a coaxial plug, and can test an antenna.

The positional relationship of the 2nd contact part 5090, the 4th contact part 5040, and the insulator 6010 becomes a preferable positional relationship in order to interrupt the connection of the 3rd contact part 4020 and the 4th contact part 5040. That is, since there is a fourth contact portion 5040 on the free end side of the switching spring 5000 on the cantilever beam, and the insulator 6010 contacts the base side rather than the contact position, the fourth contact part is on the free end side than the displacement amount of the contacted portion. The displacement amount of 5040 becomes large.

When the second coaxial plug 7000b having a central conductor with a small diameter at the tip end is mounted, the lower end portion of the outer conductor 7020b of the second coaxial plug 7000b abuts on the outer conductor 3000, and the The tip end of the center conductor 7020b is inserted through the vertical hole 2030. In this state, the center conductor 7020b of the coaxial plug abuts on the contact portion (second contact portion) 5090 of the elastic portion 5030. At this time, since the elastic force of the center conductor of the coaxial plug is stronger than the elastic portion 5030, the elastic portion 5030 is pushed down by the center conductor of the coaxial plug and elastically deformed, and the contact portion 5040 is separated from the contact portion 4020. While separated, the connecting plate 4000 and the switching spring 5000 are electrically disconnected, and the center conductor of the coaxial plug and the switching spring 5000 are connected to each other. Thereby, the signal which flowed from the switching spring 5000 to the connection board 4000 flows from the switching spring 5000 to the center conductor of a coaxial plug, and can test a high frequency circuit.

33-37 is a perspective view which shows the structure which formed the insulator 6010 in the lower surface of the connection plate 4000 of a coaxial connector in another embodiment. 33 and 34, the insulator 6010 may be formed on the lower surface of the front end portion of the elastic portion 5030 of the connecting plate 4000. In this case, when the connecting plate 4000 is pushed down by the outer edge portion 7050 of the central conductor having a large diameter, the switching spring 5000 is also pushed down by the action of the insulator 6010, and the connecting plate 4000 and It is possible to block the 촉 촉 tip of the switching spring (5000). That is, even if it is a center conductor without the protrusion 7030 as shown in FIG. 31, the center plate 7010a, 7010b does not press down the insulator 6010 directly, and the connection board 4000 and the switching spring 5000 are not pressed. The electrical connection can be interrupted.

35 and 36 are perspective views showing another configuration example of the connecting plate in the same manner as in FIGS. 33 and 34. 35 and 36, a hole 5150 is formed at two points around the hole 4070 of the elastic part 5030 of the connecting plate 4000, and a hole () is formed from the bottom surface of the connecting plate 4000. The insulator 6010 may be formed to fit the 5150. In this case, the connecting plate 4000 is pushed down by the center conductor having a large diameter, so that the switching spring 5000 is also pushed down by the action of the insulator 6010, so that the connecting plate 4000 and the switching spring 5000 The contact can be interrupted. That is, even if it is a center conductor without the protrusion 7030 as shown in FIG. 31, the center plate 7010a, 7010b does not press down the insulator 6010 directly, and the connection board 4000 and the switching spring 5000 are not pressed. The electrical connection can be interrupted.

FIG. 37: is a perspective view which shows the other structural example of a connection board similarly to FIG. 35 and FIG. As shown in FIG. 37, the notch 5170 is formed in two places of the periphery of the hole 4070 of the elastic part 5030 of the connection plate 4000, and is cut out from the side surface of the connection plate 4000 to the notch 5170. You may form the insulator 6010 together. The shape of the notch 5170 is an inclined shape in which the upper surface of the connecting plate 4000 is widest and narrows toward the lower surface. By forming the insulator 6010 in such a shape, the insulator 6010 is brought into a state where the insulator 6010 is engaged and fixed in the plate thickness direction of the connecting plate 4000, and is hardly peeled off. In addition, the same effect is acquired also as a shape of a dovetail groove shape or a zigzag shape (wave shape) instead of inclination. In this case, the connecting plate 4000 is pushed down by the center conductor having a large diameter, so that the switching spring 5000 is also pushed down by the action of the insulator 6010, so that the connecting plate 4000 and the switching spring 5000 The contact can be interrupted. That is, even if it is a center conductor without the protrusion 7030 as shown in FIG. 31, the center plate 7010a, 7010b does not press down the insulator 6010 directly, and the connection board 4000 and the switching spring 5000 are not pressed. The electrical connection can be interrupted.

As shown in FIGS. 35-37, when pressing the connection board 4000 and pressing down the switching spring 5000 via the insulator 6010, when the elastic part 5030 is comprised by several pieces, one side Even if the side of the side is not pressed down properly, the other side has the advantage of pressing down the switching spring (5000).

In FIGS. 33-37, although the structural example which formed the insulator 6010 in the lower surface of the connection plate 4000 of the coaxial connector was shown as a modification, the insulator on the switching spring 5000 side instead of the connection plate 4000 was shown. Even if 6010 is formed, the same effect and effect can be obtained. For example, the insulator 6010 is formed in the form which protrudes on both sides of the elastic part 5030 of the switching spring 5000, and the switching spring 5000 is displaced based on the pressurization and deformation of the connecting plate 4000. FIG. . The mounting of the insulator 6010 is performed by fastening the insulator 6010 by forming a hole in the switching spring 5000 as in the embodiment of Figs. Notch may be formed to fix and fasten, but may be fixed to a dovetail groove or a zigzag shape. In addition, the insulator 6010 on the lower surface side of the switching spring 5000 may be fixed to the dovetail groove in the plate thickness so as not to protrude from the surface as in the embodiment of FIG. 35. By setting it as such a structure, since the insulator is not directly contacted and pressed by a coaxial plug like the Example of FIGS. 33-37, the damage of an insulator can be prevented.

Therefore, according to the coaxial connector of the said embodiment, it is a structure of high productivity and low cost, and also high durability, and switching of multiple terminals is attained. Moreover, there is no restriction | limiting of the rotation angle at the time of insertion, and operability can be made favorable. Furthermore, by integrating the insulator, the production efficiency can be high. In addition, the gap is blocked by the insulator, and dust is hard to enter.

Moreover, you may combine suitably some of the said some embodiment, respectively.

The coaxial connector with a switch which concerns on this invention can be utilized in the wide range of industrial fields, such as the information communication device industry, such as a mobile telephone, a smart phone, a PDA, and a tablet personal computer.
