Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an L-shaped coaxial plug connector.

[Conventional technology]

Examples of connectors of this type include Jitsukai Sho.
61-99985 is known.

In this known connector, as shown in FIG. 7 of the accompanying drawings, a dielectric material 130 within an outer cylinder shell
The tip of the center conductor 151, which now protrudes from the inner dielectric 152 of the coaxial cable 150 from which the outer sheath 154 has been peeled off, is attached to the tubular center terminal 120 held so that the tip protrudes long at the center terminal. 120. On the other hand, the outer cylinder shell 110
An annular external conductor crimping receiving part 117 integrally provided through a communicating part is inserted from its tip between the internal dielectric 152 and the external conductor (shielded wire) 151 of the coaxial cable. After that, as shown in FIG. 8, the center terminal 120 is connected to the center conductor 151.
After crimping or soldering and bending the communication portion between the outer cylinder shell 110 and the outer conductor crimp receiver 117 by about 90 degrees, the crimp sleeve 140 is crimped and deformed, and the coaxial cable 150 is attached to the outer conductor crimp receiver. 117 to hold it.

In this way, the L-shaped coaxial connector is connected, and when connecting with a mating connector, the center conductor contacts the mating terminal via the center terminal to exchange signals, and the outer cylindrical shell also corresponds to this. A shield is created by contacting the opponent's Ciel.

[The problem that the idea attempts to solve]

However, such conventional connectors have the following problems.

The center terminal (center conductor) that comes into contact with the contact part of the mating connector protrudes long from the outer cylinder shell, and the L-shaped bend of the cable is made at the upper part of the center terminal, so the overall height of the back is reduced. It is expensive and cannot be used in a limited space.

The connection between the center conductor and the center terminal is done by crimping or soldering, which is a hassle.
It's hard to do again.

After inserting the center conductor into the center terminal, the communicating portion must be bent, which requires time and effort.

The center terminal must be held in the dielectric in advance.

The present invention aims to solve this problem and provide an L-shaped coaxial plug connector that is compact and easy to connect.

[Means to solve the problem]

According to the present invention, the above object is as follows:
It is equipped with an insulator that is inserted into the case through the opening, and a contact that is pressed into contact with the center conductor of the coaxial cable. A cable gripping portion is provided to grip the cable, and the insulator is arranged such that a wall portion is provided between the contact portion receiving groove that opens in one direction and receives the contact portion of the mating connector, and the contact portion receiving groove. A terminal receiving groove is formed to receive the tip of the internal dielectric of the coaxial cable from the opening from the side, and the contact is formed by bending a flat plate into a U-shape to have two legs. At least one of the legs is provided with a pressure contact groove, and the one leg is pushed in so that the one leg is located on the connection part receiving groove side and the other leg is located on the contact part receiving groove side. The leg part bites into the internal dielectric of the coaxial cable in the connection part receiving groove and presses against the center conductor in the pressure contact groove, and the other leg part is fitted and held by the wall part and connects with the contact of the mating connector. This is achieved by forming a contact portion for contact.

[Effect]

In this invention, the internal dielectric from which the outer skin has been peeled is inserted into the terminal receiving groove through the insertion opening of the case, and then the contact is inserted through the opening of the case in a direction perpendicular to the internal dielectric. When it is inserted into the inner conductor, its legs are held by the insulator inside the case, and one leg is inserted into the internal conductor and connected to the center conductor in the pressure groove.

Further, in use, when the contact of the mating connector enters the contact portion receiving groove, the contact comes into contact with the other leg of the contact of the present invention and is electrically connected.

In FIG. 1, an insulator 2 is press-fitted into a case 1 made by press-molding a conductive material such as a metal sheet to form an assembly. The case 1 opens downward and has a cylindrical cable gripping part 3 on the right side that forms a cable insertion opening. The cable gripping portion 3 is provided with a slit 3A extending in the longitudinal direction at one location in the circumferential direction,
Provides elasticity in the circumferential direction.

The insulator 2 held within the case 1 has contact portion receiving grooves 5 and connection portion receiving grooves 6 which are opened downward on both sides of the wall portion 4 and are formed in the shape described later.

On the other hand, the contactor 10 is formed by press-molding a metal plate material to have a U-shaped cross section. Among the legs 11 and 12 of the contactor 10, one leg 11 makes surface contact with the contact part of the mating connector and is substantially flat, and the contact part receiver of the insulator 2 is provided on both sides of the upper end. Claw portion 1 to prevent it from coming off when press-fitted into groove 5
1A and 11B are formed. Further, the other leg portion 12 is formed with a pressure contact groove 12A extending vertically at the center. The width of the press-contact groove 12A is set to be slightly smaller than the outer diameter of the center conductor of the coaxial cable. The tip of the other leg portion 12 is connected to the pressure contact groove 12.
It has sharp points on both sides of A so that it can be easily inserted into the internal dielectric of the coaxial cable.

The above-described insulator 2 supports one leg 11 of the contact 10 in the contact portion receiving groove 5 and the connection portion receiving groove 6.
The other leg portion 12 is received at the end.

The contact portion receiving groove 5 is a space having a shape and size suitable for receiving the contact portion of the mating connector, and guides and supports the inner surface of one leg portion 11 of the contact 10 on the back surface 4A of the wall portion 4. I'm starting to do that. Along the back surface 4A, the connection portion receiving groove 5 has a locking groove 5A for guiding the claw portions 11A and 11B of the contact.

On the other hand, the connection part receiving groove 6 has a semicircular guide surface whose bottom surface (top surface in the figure) is approximately equal to the radius of the internal dielectric material in order to receive the internal dielectric material 21 of the coaxial cable 20 until it hits the wall section 4 in the figure. It is formed to extend in the direction. Further, from the locking groove 5A to the connection portion receiving groove 6, both leg portions 1 of the contactor 10 are connected.
Another locking groove 6A is formed at a distance equal to or slightly shorter than the interval 1 and 12 so as to intersect with the bottom surface.

Next, how to use the connector of this embodiment will be explained.

First, as shown in FIG.

The contact 51 of the mating connector and the part holding it are received in the contact receiving groove 5 of the connector of this embodiment, and the contact 51 is connected to one leg 11 of the contact 10 of the connector of this embodiment. Surface contact occurs elastically (see FIG. 6), and electrical connection is established.

[Effect of idea]

According to the present invention, the following effects are brought about.

The insertion position of the coaxial cable is initially provided on the side, and the contact part of the mating connector is accommodated in the contact part receiving groove, so the total height of the connector is extremely small, making it difficult to fit into a narrow space. It can be used in

Since the center conductor and the contact can be connected by pressure welding, the work becomes extremely simple.

In addition to not requiring the effort of fitting the center terminal onto the center conductor as in the past, connection with the other connector can be made using strong contacts, making it easier to handle than when using the center terminal described above. This improves reliability.
