Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an L-shaped coaxial plug connector provided at the end of a coaxial cable.

[0002]

2. Description of the Related Art An L-shaped coaxial plug connector of this kind is connected to a metal contact pin connected to a center conductor of a coaxial cable, and to an outer conductor of the coaxial cable.
Insert the above contact pin into the inner insulating spacer (dielectric)
And a plug made of a metal cylinder held at its own axis center position at the end of the coaxial cable and arranged in a direction perpendicular to the axial direction of the coaxial cable. The base of the plug is molded with injection molding resin together with the tip of the coaxial cable.

As shown in FIG. 3, in this type of L-shaped coaxial plug connector, the connection between the cylinder 104 forming the plug portion 100 and the outer conductor 204 of the coaxial cable 200 is performed by the coaxial cable 200. A metal connecting piece 110 provided with a crimping portion 112 at the tip thereof, which is crimped to the outer conductor exposed portion 206 where the conductor 204 is exposed,
The connecting piece 110 is attached to the rear end of the cylinder 104 (that is, the end opposite to the front end connected to the mating connector) so as to extend at right angles to the cylinder 104.
Is crimped to the outer conductor exposed portion 206 of the coaxial cable 200. The connection between the contact pin 102 constituting the plug part 100 and the center conductor 202 of the coaxial cable 200 is performed by connecting the rear end of the contact pin 102 protruding from the rear end of the cylinder 104 to
The coaxial cable 200 is connected to the central conductor 202 extending from the end by soldering or electric welding.

[0004] In FIG. 3, a portion denoted by reference numeral 300 surrounded by a dashed line is a protective cover made of resin by the above-described injection molding, and the inside of the L-type coaxial plug connector is protected by moisture by the protective cover 300. Protected from dust. A connecting piece similar to the connecting piece 110 shown in FIG. 3 is attached so as to extend straight in the axial direction from the rear end of the cylinder 104, and the crimped portion of the connecting piece is connected to the outer conductor of the coaxial cable 200. After crimping to the exposed portion 206, the connection piece may be bent at a right angle.

[0005]

However, in the above-mentioned conventional L-shaped coaxial plug connector, the presence of the protective cover 300 makes it difficult to see from the external appearance.
00 is not shielded by the outer conductor 204. For this reason, it is easy for external noise to be mixed into the center conductor 202 and the contact pins 102, and conversely, radiation noise caused by high-frequency signals transmitted to the center conductor 202 and the contact pins 102 is transmitted to external electronic devices and the like. Easy to give. In particular, in recent years, digital satellite broadcasting in the several GHz (gigahertz) band has become widespread. In order to transmit such a high frequency signal of digital satellite broadcasting from a connector on the indoor wiring side to a connector on the TV tuner side, If a conventional coaxial cable for relay with an L-shaped coaxial plug connector is used, there is a great possibility that the reception level will be deteriorated.

Moreover, in the above-mentioned conventional L-shaped coaxial plug connector, the external force applied to the protective cover 300 and the bending stress applied to the coaxial cable 200 are easily transmitted to the connection point between the contact pin 102 and the center conductor 202 in the protective cover 300. Poor in durability and reliability. In particular, this problem becomes remarkable when a highly elastic resin is used as the material of the protective cover 300.

On the other hand, Japanese Utility Model Publication No. 2-12691 discloses that
The shape of the connection piece for connecting the cylinder constituting the plug portion and the outer conductor of the coaxial cable is as follows: a tip between the inner dielectric (inner insulator) and the outer conductor of the coaxial cable is provided at the end opposite to the cylinder. A cylindrical outer conductor crimp receiving portion inserted into the outer conductor is provided, and when a predetermined portion between the outer conductor crimp receiving portion and the cylinder is bent at a right angle, a central conductor extending from the end of the coaxial cable is surrounded. A space to do
It is described that a lid for closing the space is provided in front of the outer conductor crimp receiving portion.
In the above publication, such a connection piece and a cylinder are integrated, and this is called an outer cylinder shell.

In the L-shaped coaxial plug connector described in the above publication, the center conductor is not completely unshielded as in the plug connector shown in FIG. Since the shield wall that covers the conductor is formed, the shield wall cannot be set to the same potential over the entire circumference, and sufficient electromagnetic shielding properties cannot be obtained. In addition, in the L-shaped coaxial plug connector described in the above publication, when assembling to the coaxial cable, it is necessary to carefully bend the connecting piece at a right angle, and the assembling property is not good.

Accordingly, an object of the present invention is to provide an L-shaped coaxial plug connector having high electromagnetic shielding properties, high durability and high reliability, and excellent in assemblability.

[0010]

The L-shaped coaxial plug connector according to the present invention, which has been made to achieve the above object, has a tip portion of a coaxial cable in which a center conductor and an outer conductor are exposed in this order.

[0013] The cover portion of the connection holding shield member,
A shape is provided in which a cut is made in the axial direction of the bottomed cylinder whose rear end is closed, the cut being wider than the diameter of the exposed portion of the outer conductor (the portion where the outer conductor is exposed by the coaxial cable). In a state in which the end of the exposed portion of the outer conductor covers the wall of the insulating member and the center conductor of the coaxial cable and the rear end of the contact pin, the end in the axial direction is It is fitted to the rear end of the cylinder. The caulked portion of the connection holding shield member extends from a terminal position of the cut in the cover portion in a direction orthogonal to an axial direction of the cover portion, and has a cross-sectional shape surrounding the exposed portion of the external conductor. It is formed in a possible U-shape and is caulked to the outer conductor exposed portion.

In the L-shaped coaxial plug connector according to the present invention, the crimping portion of the connecting and holding shield member is crimped to the exposed portion of the outer conductor of the coaxial cable, and the distal end portion of the cover portion of the connecting and holding shield member and the cylindrical member. The connection (electric connection) between the outer conductor of the coaxial cable and the cylinder is performed by fitting the rear end of the coaxial cable. Further, in the L-shaped coaxial plug connector of the present invention, a protective cover made of resin is fixed so as to cover the entire connection holding shield member.

The assembly of such an L-shaped coaxial plug connector to a coaxial cable is performed, for example, as follows. The coaxial cable to be assembled is subjected to a peeling process in advance so that the center conductor and the outer conductor are exposed in that order (see FIG. 3). : First, the cylindrical portion of the insulating member, through which the contact pin penetrates the center of the shaft, is moved from the tip end of the contact pin to the rear end of the cylinder (ie, the end opposite to the tip end connected to the mating connector) To complete the plug portion.

Next, the center conductor and the exposed portion of the outer conductor of the coaxial cable are inserted through the cable holding hole provided on the side surface of the wall of the insulating member in this order, so that the center conductor is opposite to the cable holding hole. The contact pins protrude from the side and reach the rear ends of the contact pins protruding from the columnar portions, and the distal ends of the external conductor exposed portions are held in the cable holding holes.

Then, the rear ends of the contact pins, which are orthogonal to each other, and the center conductor projecting from the cable holding hole are electrically connected by a method such as caulking, electric welding, or soldering. : Next, the cover portion of the connection holding shield member is put on the wall portion of the insulating member so that the exposed portion of the outer conductor of the coaxial cable coming out of the wall portion of the insulating member passes through the cut of the cover portion. The front end of the cover is fitted to the rear end of the cylinder, and the caulked portion of the connecting and holding shield member is brought into contact with the exposed outer conductor of the coaxial cable coming out of the wall of the insulating member. .

In the above-described L-shaped coaxial plug connector of the present invention, the connection holding shield member not only serves to connect the cylinder to the outer conductor of the coaxial cable, but also has a cover portion having the same potential as the outer conductor. Because the contact pin and the center conductor exposed at the end of the coaxial cable and the center conductor exposed at the end of the coaxial cable are completely covered together with the end of the exposed portion of the outer conductor, the contact pin is excellent. An electromagnetic shielding effect can be obtained.

Further, since the connecting portion between the contact pin and the center conductor of the coaxial cable is surrounded by the cover of the connection holding shield member, even if a highly elastic resin is used as the material of the protective cover, the connection to the protective cover is not affected. External force is not transmitted to the connection point. In addition, since the distal end of the exposed portion of the outer conductor of the coaxial cable is held by the cable holding hole provided in the wall of the insulating member, the bending stress on the coaxial cable can also be transmitted to the connection point. Absent. Therefore, according to the L-shaped coaxial plug connector of the present invention, the durability and reliability can be made extremely high.

Further, according to the L-shaped coaxial plug connector of the present invention, when assembling to the coaxial cable,
Since the operation of bending a metal component at a right angle as in the plug connector described in the above publication is not required, the assembling property is excellent. By the way, in the L-shaped coaxial plug connector of the present invention, in order to easily and surely engage the front end portion of the cover portion of the connection holding shield member with the rear end portion of the cylinder, the configuration according to claim 2 is adopted.

That is, in this L-shaped coaxial plug connector, the front end of the cover and the rear end of the cylinder are fitted at a position where the projection and the first cut meet, and thereafter the cover and the cylinder are mutually connected. Simply twisting the protrusion so that the protrusion enters the second cut can firmly engage the two.

On the other hand, if a U-shaped conductor receiving portion for sandwiching the center conductor is provided at the rear end of the contact pin, the rear end of the contact pin and the center conductor are provided. Can be easily and reliably connected.
In other words, if the center conductor is sandwiched between the conductor receiving portions and electric welding or soldering is performed on the portion of the conductor receiving portion, the contact pins and the center conductor can be easily connected without causing displacement. it can. Also, when connecting the contact pin and the center conductor by caulking,
