Abstract
A connection part has at least two matingly interengaging contact pieces that electrically connect the central conductor of a coaxial cable without soldering or trimming. In the preferred embodiment, the connection part includes a bifurcated segment and another segment resiliently disposed between the bifurcated segment. A jig is inserted through an opening into the connection part, separating and pushing the segments apart, creating a space where the central conductor of a coaxial cable is inserted. The central conductor is pressed against a groove formed by an arcuate section of the connection part segments. When the jig is removed, the resilient action of the segments grip and bend the central conductor holding it firmly and electrically connecting it to the connection part. Bendable cover pieces close the opening. An insulative covering closes and protects the coaxial connector. Grounding arms are connected to the shielding conductor of the coaxial cable and project from slots in the insulative covering. A clamping section clamps the outermost layer of the coaxial cable securing it to the coaxial connector.
Description
BACKGROUND OF THE INVENTION
The present invention relates to a coaxial connector for connecting a coaxial cable to electrical equipment or the like. More particularly, it relates to a coaxial connector whose central contact makes resilient contact with a central conductor of a coaxial cable to establish electric connections between the connector and the cable without the use of solder and without the need to trim the central conductor after connecting.
Referring to
FIG. 12
, it is customary in the prior art to connect a coaxial cable
104
and a coaxial connector
100
by soldering the tip of a central conductor
105
to a plug pin
103
. A clamping part
107
clamps a shielded conductor
106
that surrounds central conductor
105
.
The following is a brief description of a prior art procedure for connecting coaxial connector
100
to coaxial cable
104
. To begin with, plug pin
103
, ultimately serving as a central contact, is forced into an insulating housing
102
. An external contact
101
is slid over and fixed to insulating housing
102
. Then, central conductor
105
of coaxial cable
104
is prepared by stripping and exposing a long portion of central conductor
105
and stripping and exposing a much smaller portion of shielded conductor
106
. The stripped forward end portion is inserted into plug pin
103
and passes through a hole
108
. Shielded conductor
106
is clamped by clamping part
107
. Clamping part
107
electrically connects shielded conductor
106
to external contact
101
. Coaxial cable
104
is also clamped by clamping part
107
along with shielded conductor
106
, and hence it is fixed to coaxial connector
100
.
Central conductor
105
is soldered to the tip of plug pin
103
. The portion of central conductor
105
projecting out of hole
108
is trimmed away. Next, an insulating cover
109
is mounted on the connector assembly with a contact piece
110
of external contact
101
protruding through a cutout (not shown) in insulating cover
109
. The above is atypical prior art procedure to connect coaxial connector
100
to coaxial cable
104
.
With the conventional coaxial connector it is necessary to solder central conductor
105
to the tip of plug pin
103
. After soldering, it is also necessary to cut off the portion of central conductor
105
that projects beyond hole
108
. The soldering and cutting requirements complicate the assembly of a prior art coaxial connector to a coaxial cable and hence increases manufacturing costs. It also increase the time it takes to assemble the coaxial connector in the field. In addition, such solder joints are a frequent cause of poor connections.
OBJECTS AND SUMMARY OF THE INVENTION
It is an object of the invention to provide a coaxial connector that overcomes the limitations of the prior art.
It is another object of the invention to provide a coaxial connector that is easily assembled.
It is another object of the invention to provide a coaxial connector which does not require soldering, thus reducing the cost and time required to connect a coaxial cable to a connector.
It is another object of the invention to provide a coaxial connector which does not require trimming after connecting, thus reducing the time spent connecting a coaxial cable to a connector.
It is yet another object of the invention to provide a coaxial connector that is cheaper to manufacture than the prior art.
Briefly stated, the present invention provides a connection part that has at least two matingly interengaging contact pieces that electrically connect the central conductor of a coaxial cable without soldering or trimming. In the preferred embodiment, the connection part includes a bifurcated segment and another segment resiliently disposed between the bifurcated segment. A jig is inserted through an opening into the connection part, separating and pushing the segments apart, creating a space where the central conductor of a coaxial cable is inserted. The central conductor is pressed against a groove formed by an arcuate section of the connection part segments. When the jig is removed, the resilient action of the segments grip and bend the central conductor holding it firmly and electrically connecting it to the connection part. Bendable cover pieces close the opening. An insulative covering closes and protects the coaxial connector. Grounding arms are connected to the shielding conductor of the coaxial cable and project from slots in the insulative covering. A clamping section clamps the outermost layer of the coaxial cable securing it to the coaxial connector.
According to an embodiment of the invention there is provided a coaxial connector comprising: a plug pin having a connection part; the connection part having at least two contact pieces that matingly interengage; and means for permitting urging of a central conductor against metal springback between the at least two contact pieces whereby the central conductor is positionable between same, the central conductor is resiliently retained between the at least two contact pieces by the metal springback without requiring soldering for mechanical and electrical connection.
According to another embodiment of the invention, there is provided a coaxial connector for attachment to a coaxial cable which has been prepared by stripping back an outer conductor exposing a portion of an inner conductor, comprising: an external contact; a plug pin coaxially disposed in the external contact; means for electrically isolating the external contact from the plug pin; the plug pin having a plug end extending beyond an end of the external contact; the external contact having at least one external contact surface for contacting a socket; the plug pin also having a connection part disposed at an other end; the connection part having at least two contact pieces that matingly interengage; and means for urging a central conductor against metal springback between the at least two contact pieces whereby the central conductor is positionable between same, the central conductor is resiliently retained between the at least two contact pieces without requiring soldering for mechanical and electrical connection.
According to yet another embodiment of the invention, there is provided a coaxial connector comprising: a plug pin having a connection part; the connection part having at least two contact pieces that resiliently interengage; and means for temporarily urging the at least two contact pieces apart forming a channel, whereby the central conductor is insertable in the channel and once the central conductor is inserted in the channel, the at least two contact pieces resiliently move back together deforming the central conductor, resiliently retaining the central conductor against axial forces without requiring soldering for mechanical and electrical connection.
The above, and other objects, features and advantages of the present invention will become apparent from the following description read in conjunction with the accompanying drawings, in which like reference numerals designate the same elements.

.
Referring to
FIGS. 3-7
and
10
(
a
)-(
e
) coaxial connector
1
is assembled by pressing plug pin
4
into cylindrical hollow
32
through the rearward end of same. External contact

2
. Lug
23
slides against stepped portion
31

. Lug
23
engagingly secures external contact
2
to the outside of insulating housing

.
Shielded conductor
42
and central conductor
41
of coaxial cable
5
are stripped. Central conductor
41
is connected to connection part
11
and shielded conductor
42
is connected to external contact
2
. The connection between central conductor
41
and connection part
11
will be described in detail infra.
Central conductor
41
of coaxial cable
5
is initially positioned slightly above connection part
11
near central axis O as coaxial cable
5
is inserted into external contact
2
from its rearward end. Accordingly, stripped central conductor
41
lies just above contact pieces
12
and
13
of connection part
11
. Next, a jig
50
, is guided through cutout
33
in insulating housing
3
. In this position, central conductor
41
is straddled by pressing projections
53
of jig
50
. The structure of jig
50
is described infra. As jig
50
is guided into the position shown in
FIG. 5
, first and second contact pieces
12
and
13
are pressed apart by the bottom of jig
50
. Central conductor
41
is guided down and aligned along central axis O by jig
50
into groove
15
defined by the two segments of second contact piece
13
.
Upon removal of jig
50
, first and second contact pieces
12
and
13
go back towards their initial positions by their own resiliency. Central conductor
41
is guided down against groove
15
and is urged against second contact piece
13
by first contact piece
12
. This securely positions central conductor
41
in groove
15
. Central conductor
41
is firmly held between first and second contact pieces
12
and
13
which are electrically connected to plug pin
4
. Central conductor
41
is easily bent by a slight external force. Thus the resilient action of first and second contact pieces
12
and
13
bends the small portion of central conductor
41
that is held between first and second contact pieces
12
and
13
. This provides a secure electrical connection between central conductor
41
and connection part
11
at a plurality of places preventing central conductor
41
from easily dislodging.
Referring to
FIGS. 5 and 11
, jig
50
has downward projections
53
which straddle first and second contact pieces
12
and
13
when jig
50
is inserted through cutout
33
. Central conductor
41
is straddled by projections
53
as jig
50
is inserted and is pushed down into position by a notched portion
70
. Projections
53
push and separate first and second contact pieces
12
and
13
allowing central conductor
41
to be properly seated along center axis O. First and second contact pieces
12
and
13
resiliently grip central conductor
41
as jig
50
is removed.
Referring now to FIG.
10
(
c
), shielded conductor
42
and external contact
2
are connected to each other by inserting inner clamping portion
21
between inner insulator
40
and shielded conductor
42
. Next, outer clamping portion
22
and inner clamping portion
21
clamp shielded conductor
42
and inner insulator
40
together. As a result, shielded conductor
42
of coaxial cable
5
and external contact
2
of coaxial connector
1
are securely fixed and electrically connected to each other. Following this, sheath clamping portion
17
clamps the outer sheath of coaxial cable
5
. This securely fixes coaxial cable
5
to external contact
2
.
Referring now to FIGS.
9
and
10
(
c
)-(
d
), once coaxial cable
5
is connected to external contact
2
, coupling piece
24
is severed from carrier
27
at a position just behind sheath clamping portion
17
. Inner clamping portion
21
, once clamped, is firmly fixed by outer clamping portion
22
to coaxial cable
5
and will not fall out when coupling portion
24
is severed.
Referring now to FIGS.
7
and
10
(
e
), once the above has been accomplished, cover pieces
28
of external contact
2
are bent from the positions indicated by the broken lines along a radius of the cylindrical portion of external contact
2
. In this way, cover pieces
28
cover the opening above connection part
11
. This shields central conductor
41
from the outside and protects it against unwanted radiation and external noise. Then, insulating cover
7
is slid over external contact
2
from the front until the rearward end of cover
7
engages with insulating cap
8
. Plug pin
4
projects out of through hole
52
. Contact pieces
26
protrude through cutouts (not shown) in cover
7
. Insulating cover
7
and insulating cap
8
are fixed to each other.
Coaxial connector
1
is connected to a mating connector (not shown.) Pin plug
4
makes contact with a central terminal (not shown) of mating connector. Contact piece
26
makes contact with a grounding terminal (not shown) of mating connector.
Because central conductor
41
of coaxial cable
5
is electrically connected to plug pin
4
of coaxial connector
1
by the resilient action of connection part
11
, coaxial connector
1
is easily assembled to coaxial cable
5
without soldering and severing central conductor
41
as is required in the prior art. This reduces the manufacturing costs of coaxial connector
1
.
Central conductor
41
of coaxial cable
5
is gripped by resilient first and second contact pieces
12
and
13
and is positioned in groove
15
. This ensures that central conductor
41
is securely connected both mechanically and electrically. This arrangement prevents central conductor
41
from dislodging during use.
Because second contact piece
13
is bifurcated, two segments firmly grip central conductor
41
in combination with first contact piece
12
which is matingly disposed between the two segments. This ensures that connection between central conductor
41
and connection part
11
is secure and prevents central conductor
41
from dislodging during use.
While the above descriptions have utilized a plug pin (serving as a central contact) and a connection part that are integrally formed, it is not necessary that they be a unitary structure using the same material. One skilled in the art would recognize that they could be formed as separate parts as long as they are electrically connectable.
Furthermore, although groove
15
has been described to be defined by second contact piece
13
, it may also be formed on first contact piece
12
.
Additionally, jig
50
does not have to be used to place central conductor
41
in position. Central conductor
41
may be manually inserted axially into position after jig
50
pushes first and second contact pieces
12
and
13
apart. Contact pieces
12
and
13
are released to grip central conductor
41
in position. Outer clamping portion
22
may be crimped into position on shielded conductor
42
either before or after clamping central conductor
41
. Although the preferred embodiment includes jig
50
, it is possible to spread first and second contact pieces
12
and
13
using nonspecific tools such as a screwdriver or nail without departing from the scope or spirit of the invention.
Contact pieces
12
and
13
are not limited specifically to the configurations described above. Other examples of contact pieces include a trifurcated contact piece providing three segments matingly interengaging another bifurcated contact piece with the segments firmly received between them.
First and second contact pieces
12
and
13
matingly engage each other, bending central conductor
41
which locks it into position within groove
15
. This ensures sufficient contact pressure is applied to central conductor
41
. Because central conductor
41
is supported in groove
15
, it will remain in position even if subjected to external forces.
Moreover, since connection part
11
is resiliently connected to central conductor
41
by utilizing the resiliency of a band-shaped metal sheet which extends over the entire length thereof, only a small amount of force is required to insert central conductor
41
into coaxial connector
1
. Therefore, even if central conductor
41
is readily bendable, it can be connected to connection part
11
. Furthermore, once connected, central conductor
41
bends between end portions of first and second contact pieces
12
and
13
. This establishes electrical connections at a plurality of positions along central conductor
41
. Hence, the reliability of the connection is increased.
There are many types of coaxial cables in use. Some coaxial cables lack an outer insulative covering. The invention works with all types of coaxial cables. On coaxial cables lacking an outer insulative layer, both outer clamping portion and cable sheath clamping portion are crimped around the outer conductive layer.
Having described preferred embodiments of the invention with reference to the accompanying drawings, it is to be understood that the invention is not limited to those precise embodiments, and that various changes and modifications may be effected therein by one skilled in the art without departing from the scope or spirit of the invention as defined in the appended claims.
