Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to equipment installed in a television radio wave supply path, particularly to a coaxial cable connector for an antenna power supply terminal.

[Conventional technology]

As shown in FIGS. 4 and 5, a conventional connector of this type connects a braided portion 34 at the tip of a coaxial cable 33 inserted through a hole 32 into a main body 31 of an antenna power supply terminal to a contact terminal. Part 3
The contact plate 36 of 5 and the arc-shaped conductor holding groove 38 of the presser foot 37 are clamped with a pinch screw 39, and the core wire 4 at the tip is
0, the coaxial cable 33 was attached to the contact terminal mounting portion 35 by clamping the contact terminal plate 41 of the main body portion 31 and the holding piece 42 with a clamping screw 43.

[Problem that the invention attempts to solve]

However, the contact terminal plate 41 of the contact terminal mounting portion 35
In order to connect the core wire 40 to the contact terminal plate 41, a holding piece 42 and a screw 43 are required, which increases the number of parts, and also requires tools such as a screwdriver, making it troublesome to install the core wire. The disadvantage is that it takes time.

The present invention was devised in view of the above points, and provides a coaxial cable connector that minimizes the number of parts for attaching the core wires, does not require any tools, and can be installed easily and quickly by hand. With the goal.

[Means for solving problems]

The structure of the present invention for achieving this object will be explained using FIGS. 1 to 3 corresponding to the embodiments.

In a device in which the core wire 5 and the braided portion 6 of the coaxial cable 3 are individually connected to the connection terminal provided in the main body 1 of the device, the core wire attachment point 4 of the main body 1 has a direction in which the coaxial cable is inserted. A core wire terminal 11 is fitted so as to be movable back and forth in a direction intersecting with the core wire, and has a bent terminal portion 12 at one end and a core wire insertion hole 13 near the bent terminal portion;
2, and a locking piece 16 that engages and disengages from the locking piece 1.
Reference numeral 6 is configured to lock the bent terminal portion 12 with the core wire 5 sandwiched between the bent terminal portion 12 and the wire attachment location 4.

[Effect]

When the coaxial cable 3 with the core wire 5 and the braided portion 6 exposed at the tip is inserted into the main body 1, the core wire 5 is first inserted into the through hole 13 of the core wire terminal 11, and then the braided portion 6 is inserted into the main body 1. It is attached to the contact plate 9 according to the attachment method.
Next, by pressing the bent terminal portion 12 of the core wire terminal 11 against the core wire attachment location 4 with your finger, the pair of locking pieces 1 are released.
6 is pushed open to both sides by the core wire terminal 11, and when the core wire terminal 11 passes through, it closes and locks the terminal portion 12, and as a result, the core wire 5 is brought into contact with the core wire attachment location via the terminal portion 12. Bent terminal portion 12 of core wire terminal 11
and the core wire 5 will be reliably connected.

〔Example〕

Embodiments of the present invention will be described based on the drawings. 1st
3, in the lower half of the end face 4 facing the coaxial cable 3 insertion side of the contact terminal attachment part 2 of the main body part 1 of the antenna power feeding terminal, there is a core wire exposed at the tip of the coaxial cable 3. A contact plate 9 is attached to sandwich the braided part 6 of the braided part 5 and the braided part 6 with the arc-shaped conductor holding groove 8 of the presser foot 7. A through hole 10 having an appropriate shape such as a circle (square in this embodiment) in cross section is formed perpendicular to the insertion direction of the coaxial cable 3, and a core wire terminal 11 is removably inserted into this through hole 10. .

The core wire terminal 11 has a bent terminal portion 12 formed at one end, a core wire insertion hole 13 provided adjacent to this, and a bent piece 14 that engages with the through hole 10 at its tip edge in the middle portion.
is formed. This bent piece 14 is formed at an obtuse angle with respect to the upper surface 15 of the terminal on the insertion side, so that insertion of the core wire terminal 11 into the through hole 10 is easy, but it is difficult to pull it out. On the other hand, the through hole 10 of the end surface portion 4
A locking piece 16 is provided protruding from both sides of the opening, and the end face 4
The bent terminal part 12 is locked in a state where the core wire 5 is sandwiched between the bent terminal part 12 and the bent terminal part 12.

The coaxial cable 3 with the core wire 5 and the braided portion 6 exposed at the tip is inserted into the main body 1 through the hole 17. First, the core wire 5 is inserted into the through hole 13 of the core wire terminal 11, and then the conductor holder is inserted. The presser foot 7 fitted into the braided part 6 in the groove 8 is attached to the contact plate 9 with screws 18 to fix the braided part 6 to the contact plate 9 (FIG. 2). Next, wire terminal 1
When one bent terminal part 12 is pressed against the end surface part 4 with a finger, the pair of locking pieces 16 are pushed by the bent terminal part 12 and open to both sides, and then lock the bent terminal part 12 that has passed through. . That is, since the bent terminal portion 12 of the cable terminal 11 is locked by the pair of locking pieces 16 with the cable core 5 in contact with the end face portion 4, the cable terminal 11 and the cable core 5 are locked together by the pair of locking pieces 16. It will definitely connect. In addition, the core wire 5 is bent toward the terminal insertion side by the through hole 13 and loses its restoring force, and the core wire terminal 11 has a pull-out resistance force due to the bending piece 14, so that the core wire 5 and A reliable connection is maintained.

[Effect of idea]

As explained above, according to the present invention, the core wire attachment mechanism consists of a pair of locking pieces formed at the core wire attachment location and a core wire terminal, so the number of parts is minimized, making handling easier and reducing costs. useful for. Moreover, since the connection can be easily made by pressing with a finger, it can be done more easily and quickly than the conventional method of fixing with screws, and has the advantage of eliminating the need for screws and drivers.
