Description
1 - 2282493 "COAXIAL CONNECTOR HAVING IMPROVED CONSTRUCTION, REDUCING
MANUFACTURING COST, AND MANUFACTURING METHOD THEREOP' The present invention relates to a coaxial connector and a manufacturing method thereof. The coaxial connector according to the present invention is a connector which is installed onto a circuit substrate and into which connector a coaxial cable is fitted so that an electrical connection is formed between the conductor in the cable and a predetermined circuit in the substrate.
A coaxial connector in the related art is now described with reference to FIGS.1 and 2. The coaxial connector 10 in the related art includes a housing 11 acting as a peripheral contact member, a signal terminal 12, a male contact member 13, insulating members 14 and 15, grounding terminals 16_1 through 16 4, a spacer 17 and a lid 18.
The coaxial connector 10 is installed onto a circuit substrate 19 by being soldered at the terminals 12, and 16_1 through 16-4 to the substrate 19. A coaxial cable is connected to the coaxial connector 10. The coaxial cable, not shown in the figure, has a plug connector provided at the end thereof, not shown in the figure, having a female contact member matching the male contact member 13. The plug connector is fitted to the connector 10 so that the coaxial cable is fastened to the coaxial connector 10. A method of manufacturing such a coaxial connector is described with reference to FIG.3. The housing 11 is formed as follows: a) A cutting step 30 cuts a work so as to form a desired shape of the housing 11; 35 b) a grounding terminals fixing step 31 fixes the grounding terminals 16_1 through 16-4 to the housing 11; and 1 c) a plating step 32 plates the housing 11 together with the terminals 16_1 through 164. A terminal-insulating assembly 21 is formed as follows: 5 a) A cutting step 33 cuts and then a plating step 34 plates a work so as to form the terminal 12; c) a molding step 35 forms the insulating member 14; and d) a press-fitting step 36 press-fits the terminal 12 into the insulating member 14 so that the assembly 21 is obtained.
A male-contact-insulating assembly 22 is formed as follows:
a) A cutting step 37 cuts and then a plating step 38 plates a work so as to form the male contact member 13; c) a molding step 39 forms the insulating member 15; and d) a press-fitting step 40 press-fits the terminal 13 into the insulating member 15 so that the assembly 22 is obtained.
The coaxial connector 10 is formed as follows:
a) A press-fitting step 41 press-fits the terminal-insulating assembly 21 into the housing 11 at the bottom thereof; b) a press-fitting step 42 press-fits the male- contact-insulating assembly 22 into the housing 11 at the front thereof; c) a soldering step 43 solders the male contact member 13 and the terminal 12 together using solder 23; d) a lid step 44 provides the lid 18 on the top of the housing 11; and 35 e) a spacer step 45 provides the spacer 17 on the bottom of the housing 11. The manufacturing cost of such a coaxial 1 connector in such a manner is increased due to a step such as the cutting step 30 for forming the shape of the housing 11, a large number of components such as those constituting the connector 10, and a large number of steps such as those constituting the manufacturing method.
An object of the present invention is to provide a coaxial connector and a manufacturing method thereof enabling manufacturing cost reduction.
To achieve the above object, a coaxial connector according to the present invention comprises:
a peripheral contact portion manufactured by die-cutting a metal plate and bending it; and an insulating portion for insulating between said peripheral contact portion and a central contact portion.
The above connector may preferably have a construction further comprising a body including said peripheral contact portion; and wherein:
said body further comprises a housing portion; said peripheral contact portion extends from said housing portion; said body further comprising a grounding contact portion; said insulating portion is located within said housing portion; and a middle part of said central contact portion being located within said insulating portion, a first end of said central contact portion being a first contact portion and projecting in a direction in which said peripheral contact portion extends, a second end of said central contact portion being a second contact portion and projecting in a direction in which said grounding contact portion extends.
Such a metal-plate die-cutting body formation 1 method may reduce the manufacturing cost in comparison to an ordinary metal cutting body formation method. Further, obtaining both the first contact portion for making a connection with the coaxial cable and second contact portion for making a connection with a circuit substrate made of a single central contact portion for example reduces the number-of components.
The above connector may preferably have a construction, wherein:
said housing portion comprises a top plate, left and right side plates and a rear plate; said peripheral contact portion extends frontally and said grounding contact portion extends downward; said insulating portion has a cubic like shape; and said central contact portion is L-shaped so that said first end projects frontally and said second end projects downward.
The above connector may preferably have a construction, wherein a concavity is formed in said insulating portion so that said central contact portion is fitted into said concavity.
The cubic-shape of the insulating portion prevents the orientation of the insulating portion from being shifted after being inserted into the housing portion. The L-shape of the central contact portion provides the right-angle between the directions of the first contact portion and second contact portion.
The above connector may preferably have a construction, wherein a knot portion is formed on said central contact portion so that said knot portion prevents said central contact portion from shifting after being fitted into said concavity. Thus, the connector construction having the Lshaped central contact portion may be simply realized.
Further, the above object of the present invention will be achieved by a method, for manufacturing a coaxial- connector according to the present invention, which comprises:
a) a peripheral-contact-portion forming step for forming a peripheral contact portion by die-cutting and bending a metal plate; b) an insulating-portion forming step for forming an insulating portion for insulating between said peripheral contact portion and a central contact portion; and c) an assembling step for assembling said insulating portion and said peripheral portion.
The above method may preferably have an additional manner wherein:
said peripheral-contact-portion forming step a) further forms a body including said peripheral contact portion, a housing portion from which said peripheral contact portion extends and a ground contact portion; said insulating-portion forming step b) fits said central-contact portion into said insulating portion, a first end of said central contact portion being a first contact portion and a second end of said central contact portion being a second contact portion; and said assembling step c) inserts said insulating portion into said housing portion and then bends a predetermined part of said housing portion so as to prevent said insulating portion from escaping from said housing portion.
The above method may preferably have a manner wherein:
said peripheral-contact-portion forming step a) forms said body comprising said housing portion including a top plate, left and right side plates and a rear plate, said peripheral contact portion extending frontally and said grounding contact portion extends 1 downward, and said insulating portion has a cubic like shape; said insulating-portion forming step b) uses said central contact portion L-shaped so that said first end projects frontally and said second end projects downward, a concavity formed in said insulating portion so that said central contact portion is fitted into said concavity, and a knot portion formed on said central contact portion so that said knot portion prevents said central contact portion from shifting after being fitted into said concavity.
Thus, the number of steps may be reduced, economical components may be used and also the number of components may be reduced, in the connector manufacturing. As a result, the manufacturing cost may be reduced.
Other objects and further features of the present invention will become more apparent from the following detailed description when read in conjunction with the accompanying drawings.

A coaxial connector 10 in one embodiment of the present invention is described with reference to FIGS.4-8.
The coaxial connector 10 includes a body 51, an L-shaped contact member 52 and an insulating member 53.
The body 51 is manufactured through a pressing process including die-cutting of a metal plate and then bending it. The body 51 includes a housing portion 51A, a peripheral contact portion 51B and a grounding terminal portion 51C.
The housing portion 51A includes a top portion 51A_,, left and right side portions 51A-2 and 51A0-3 and a rear portion 51A-4. The side portions and rear portion 51A-21 51A-3 and 51A-4 are formed by bending the proper parts of the metal plate at the right angles to the top portion 51A_1. The housing portion 51A having a cubic-like shape has a full-face opening 54 at the front thereof and also has a full- face opening 54 at the bottom thereof.
Nail portions 54A-4a and 54A-4b (shown in FIG.5) of the rear portion 51A4 respectively engage with holes 51A-2a and 51A-3a of the side portions 51A so that the rear portion 51A-4 is fixed to the side portions 51A-2 and 51A-3.
Cut-raised portions 51A-2b and 51A-3b are formed in the side portions 51A2 and 51A-3 and used to compress and hold the insulating member 53 using the elasticity of the metal constituting the portions 51A 2b and 51A-3b after the member 53 has been inserted into the housing 51A. Preventing portions 51A_1a and 51A_ib (shown in FIG.4) are formed at the front of the top portion 51A-i so as to be bent at right angles. Preventing portions 51A-2c and 51A-3c (shown in FIG.7E) are formed at the bottom of the side 30 portions 51A-2 and 51A-3 so as to be bent at right angles.
The above preventing portions 51A_1a, 51A_Ibl, 51A-2c and 51A-3c prevent the insulating member 53 from escaping from the housing portion 51A.
A ridge portion 51A-4c (shown in FIG.5) is formed in the rear portion 51A4 for the purpose of reinforcement.
1 The peripheral contact portion 51B includes a pair of arm portions 51B-1 and 51B-2 front projecting and tapered from the side portions 51A-2 and 51A-3.
The arm portions 51B-1 and 51B-2 are bent inward so as to approach one another as the positions are away from the side portions 51A-2 and 51A-3, The ends of the arm portions 51B_1 and 51B-2 are bent outward so as to form socket portions 51B_la and 51B-2a, the bent angular portions being contact portions 51B_la and 51B-2a The grounding terminal portion 51C includes a grounding terminal portion 51A-2d extending downward from the side portion 51A-2, a grounding terminal portion 51A_3d extending downward from the side portion 51A-3, and two grounding terminal portions 51A-4d and 51A-4e extending downward from the rear portion 51A-4.
The above grounding terminal portions 51A-2d and 51A-3d include bent portions 51A-2d-, and 51A-3d-1 shown in FIG.7C at the base parts thereof. The bent portions 51A-2d-, and 51A-3d-I are bent inward as shown in FIG.7C and thus, together with the preventing portions 51A-2c and 51A-3c, prevent the insulating member 53 from escaping from the housing portion 51A.
The insulating member 53 is now described with reference to FIGS.9-12.
The insulating member 53 is formed of Teflon (trade mark) through a molding process and is a cubic shaped block having dimensions suitable to be fitted into the above housing portion 51A.
A slit 53a is formed in the insulating member 53 over the front face through the bottom face of the member 53. The slit 53a has an L-shaped inside-edge as shown in FIG.11. A circular cross-sectional groove 53b, having the diameter d identical to the diameter of the L-shaped contact member 52, is formed along the above L-shaped inside edge as shown in FIG.12. The L shaped contact member 52 is press-fitted into the slit 53a. The groove 53b prevents the L-shaped contact 1 member 52 from escaping from the inside edge of the slit 53a after the member 52 has been inserted into the groove 53b. Since the insulating member 53 is formed of Teflon as mentioned above having elasticity, the slit 53a may be expanded by the elastic transformation of the member 53. Assuming the expansion of the slit 53a, the width W of the slit 53a is determined smaller than the diameter d of the L-shaped contact member 52.
As shown in FIG.10, guide grooves 53c and 53d are formed on the side walls of the insulating member 53.
The L-shaped contact member 52 is now described with reference to FIGS.13A and 13B.
The bottom end of the member 52 is a signal terminal portion 52a and the front end of the member 52 is a female contact portion 52b. A first knot portion 52d is formed at the rear end of the female contact portion 52b and a second knot portion 52c is formed at the top end of the signal terminal portion 52a. The part of the member 52 between the two knot portions 52c and 52d is a L-shaped middle portion 52e.
The female contact portion 52b includes a pair of contact pieces 52b_1 and 52b-2, each of which are tapered.
The overall construction of the coaxial connector 50 including the above components will now be described.
The assembling manner of the L-shaped contact member 52 with the insulating member 53 will now be described with reference to FIGS.5-8. The L-shaped middle portion 52e is fitted in the groove 53b, so that the knot portion 52c is in contact with the bottom face 53e of the insulating member 53, and the knot portion 52d is in contact with the front face 53f of the insulating member 53.
Further, as the insulating member 53 is compressed by the housing portions 51a via the cut- 1 raised portions 51A-2b and 51A-3b as mentioned above, the insulating member 53 clamps the L-shaped contact member 52 placed in the groove 53b.
As shown in FIG.4, 7 and 8, the insulating member 53 is integrated into the housing portion 51A.
The preventing portions 51A-1a and 51A_lb of the housing portion 51A prevent the insulating member 53 from shifting frontally (in the X direction shown in FIG.8). The preventing portions 51A-2cr 51A-3c and bent portions 51A-2d-, and 51A-3d-1 prevent the insulating member 53 from shifting downward (in the direction Z). Thus, the insulating member 53 is prevented from escaping from the housing portion 51A.
As shown in FIG.8, the female contact portion 52b of the contact member 52 frontally projects within the peripheral contact portion 51B from the insulating member 53.
The coaxial construction in the coaxial connector 50 is now described. As shown in FIG.7E, the grounding terminal portions 51A-2d, 51A-3d, 51A-4d and 51A-4e project downward from the positions near the four corners of the bottom face of the body 51. The signal terminal portion 52a projects downward from the position near the center of the body 51. The female contact portion 51A acts as the central contact portion and is located at the center of the arm portions 51B_l and 51B-2 acting as the peripheral contact portion in the coaxial construction at the external connecting part of the coaxial connector. As shown in FIG.8, the Teflon made insulating member 53 insulates the L-shaped contact portion 52 from the metallic body 51. The L shaped contact member 52 acts as the central conductor, the body 52 act as the peripheral conductor and the insulating member 53 acts as the intermediate insulating member in the coaxial construction of the entirety of the coaxial connector 50.
How the coaxial connector 50 is used is now I described.
As shown in FIG.8, the connector 50 is installed onto a circuit substrate 60. The grounding terminal portions 51A-2d, 51A-3d, 51A-4d and 51A-4e are soldered to a grounding pad(s) (not shown in the figure) of the substrate 60 and the signal terminal portion 62a is soldered to the appropriate signal pad (not shown in the figure).
As shown in FIG.8, a plug connector 61 provided at an end of a coaxial cable (not shown in the figure) is inserted into the peripheral contact portion 51B so that the cable is electrically connected to the connector 51 and thus is electrically connected to the circuit substrate 60. The plug connector 61 which has been fitted into the peripheral contact portion 51B is shown in FIG.8 with chain double-dashed lines. The plug connector 61 has a male contact portion 62 at the center thereof and insulating member 63 at the periphery of the male contact portion 62. The plug connector 61 further has a metal-made pipe portion 64 enclosing the insulating member 62. If the plug connector 61 is inserted into the connector 50, as shown in FIG.8, the male contact portion 62 is inserted into the female contact portions 52b and the insulating member 63 encloses the female contact portions 52b. Further, the metallic pipe portion 64 comes into contact with the contact portions 51B_lb and 51B-2b Thus, the female contact portions 52b, the insulating member 63 and both the metallic pipe portion 64 and the peripheral contact portions 51B constitute the coaxial construction.
A manufacturing method of such a coaxial connector is now described with reference to FIGS.1417.
With reference to FIG.14, the body 51 is manufactured as follows:
a) A primary pressing step 70 (see FIGS.15A, 1 15B and 15C) presses a hoop-shaped metal plate to be used as a work so as to die-cut it and bend the appropriate portions thereof to obtain the shape which is one obtained as a result of unfolding the body 51 shown in FIG.4, the primary processed work 90 being thus obtained; b) a plating step 71 then plates nickelpalladium on the entirety of the above primary processed work 90 and plates gold on the portions of the work which become the arm portions 51B-1 and 51B-2; c) a secondary pressing step 72 (See FIGS.16A, 16B, 16C and 16D) then presses the plated primary processed work 90 so as to bent to form the side portions 51A-2 and 51A-31 the secondary processed work 91 being thus obtained; d) a cutting step 73 cuts the work 91 along the lines 92 and 93 so as to obtain the body 51 shown in FIG.5.
The thus obtained body 51 has the rear portion 51A-4 which has not been downward bent as shown in FIG.5 so that the full extent of the rear face of the housing portion 51A is opened and referred to as an opening 94.
The L-shaped contact member 52 is manufactured as follows:
a) A cutting step 74 cuts a material so as to form a line-shaped contact member and cut a material so as to form the female contact portion 52b; b) a drilling step 75 (see FIG.17A) drills an end of the line-shaped contact member so as to form a hole 95 along the center axis of the line-shaped contact member; c) a slit forming step 76 (see FIG.17B) forms the slits 96 on the end of the line-shaped contact member so as to form the contact portions 97 and 98; d) a pressing step 77 (see FIG.17C) vertically compresses the contact portions 97 and 98 so 1 as to bend them inward, the contact portions 52b_1 and 52b-2 and the female contact portion 52b being thus formed; e) an L-shape bending step 78 (see FIGS.13A and 13B) then bends the line-shaped contact member by the right angle; and f) a plating step 79 then plates the resulting work, the L-shaped contact member 52 shown in FIGS.13A and 13B being thus obtained.
The insulating member 53 is manufactured through a molding step 80 molding the insulating member 53 having the slit 53a and groove 53b shown in FIGS.6, 9A, 9B, 9C, 10 and 11.
An 'L-shaped contact portion - insulating member assembly' 100 is fabricated by a press-fitting step 81 (see FIGS.5, 6 and 8) presses the L-shaped middle portion 52e of the L-shaped contact member 52 into the slit 53a in the direction 101 shown in FIG.6, the L-shaped contact member 52 expanding the space in the slit 53a so as to pass therethrough, until the L shaped middle portion 52e is placed in the groove 53b.
Thus, the middle portion 52e is fitted into the groove 53b, the knot portion 52c comes into contact with the bottom face 53e of the insulating member 53 and the knot portion 52d comes into contact with the front face 52f of the insulating member 53. Thus, the L-shaped contact member is integrated with the insulating member 53.
The entirety of the coaxial connector 50 is manufactured by an inserting step 82 (see FIG.5) inserts the L-shaped contact portion - insulating member assembly 100 into the housing portion 51A in the direction 102 shown in FIG.5 through the rear opening 94 of the housing portion 51A. The engagement of the guiding grooves 53c and 53d with cut-raised portions 51A-2b and 51A-3b controls the insertion movement (direction) of the assembly 100 (insulating member 53) 1 into the housing portion 51A.
Then, as shown in FIG.4, a closing step 83 bends the rear portion 51A-4 in the direction shown in FIG.5 so as to close the rear opening 94 of the housing portion 51A. Then, the nail portions 51A-4a and 51A-4b are respectively engaged to the holes 51A-2a and 51A-3a so that the rear portion 51A-4 is locked to the side portions 51A-2 and 51A-3.
Thus, the coaxial connector 50 shown in FIG.4 is obtained.
The female contact portion 52b of the L shaped contact member 52 may be replaced by a male contact portion, matching a female contact portion replacing the male contact portion 62 in the plug connector 61.
Further, the present invention is not limited to the above described embodiments, and variations and modifications may be made without departing from the scope of the present invention.
