Description

[Detailed description of the invention] The invention relates to a coaxial connector that can be used to connect a coaxial cable to the antenna terminal board of a television receiver, and its purpose is to facilitate assembly and disassembly of the coaxial connector. .

One embodiment will be described below with reference to the accompanying drawings. FIG. 1 shows a molded product body including a connection terminal portion for connecting a coaxial cable, and FIGS. 2a and 2b show a lid of this molded product body. In the figure, reference numeral 1 denotes the molded product body, which has rail parts 2 formed at both ends of a board part 1a, and a 75Ω coaxial cable 3 on a vertical plate part 1b that protrudes perpendicularly from one end of the board part 1a.
A through hole 4 is provided through which the through hole 4 passes. Furthermore, a parallel plate part 1c is continuously provided at the tip of the vertical plate part 1b, and is parallel to the base plate part 1a, and a stopper protrusion 5 is integrally formed on the surface of this parallel plate part 1c so as to be located at the tip. Further, an engaging protrusion 6 is integrally provided so as to be located closer to the vertical plate than the protrusion 5. 7 is a terminal into which the core wire 3a of the coaxial cable 3 is inserted and connected, and 8 is a terminal to be connected to the ground conductor 3b of the coaxial cable 3. A pair of caulking pieces 8a that also mechanically hold the ground conductor 3b connect the ground conductor 3b. It is also electrically connected to. These terminals 7 and 8 are installed on one surface of the molded product main body 1a, and the terminal 7 is connected to an inner terminal 9 that protrudes from the other surface of the molded product main body 1a. The terminal 8 is connected to the metal fitting 10.

In FIG. 2, the lid body 11 has a pair of grooves 12 on its inner wall into which the rail portion 2 of the molded product body 1 is slidably fitted.
is provided, and the protrusion 6 is provided on the inner surface of the top plate portion.
A recess 13 with which the protrusion 5 engages, and a recess 14 with a large enough area to allow movement of the protrusion 5 and with which the protrusion 5 engages are provided at one end.

4 and 5 show the state in which the molded product main body 1 and the lid body 11 are combined (combined). By sliding the rail portion 2 of the molded product body 1 along the groove 12 of the lid body 11, the molded product body 1 and the lid body 11 can be integrated, and the coaxial cable 3 and the terminals 7, 8 can be integrated.
The connecting portion can be covered with the lid 11. That is, at this time, as shown in FIG. 4, the protrusion 5 that first engages with the recess 14 is located at the back of the recess 14, and the protrusion 6 engages with the recess 13, thereby connecting the molded product body 1. It can be integrated with the lid body 11. At this time, the state of engagement between the protrusion 6 and the recess 13 is strengthened by the protrusion 6 being located at the base of the parallel plate part 1c, but it is also made stronger by taking into account its shape, height, etc. The lid body 11 and the molded product main body 1 are kept in such a way that they cannot be easily disassembled.
On the other hand, when the protrusion 6 and the recess 13 are not engaged with each other as shown in FIG. so that it can be easily removed. One means for this is to provide a protrusion 5 at the tip of the parallel plate portion 1c as shown in the figure. That is, at the time of shipment from the manufacturer, only one tip end protrusion 5 is engaged with the recess 14 as shown in FIG. The molded product main body 1 and the lid body 11 must be separated from each other, but by setting the engagement state between the protrusion 5 and the recess 14 weakly as described above, this separation becomes easy, and the terminal 7 , 8, and then the protrusion 5 and the recess 14 are fitted together, as well as the protrusion 6 and the recess 13 are engaged, as shown in FIG. 4, so that the connection is extremely strong. Become. Figure 6 shows the completed state.

As explained above, according to the present invention, the first and second protrusions are provided on the parallel plate portion of the molded product body at intervals in the sliding direction, and the first and second protrusions are provided on the lid body. The first and second parts fit together (engage), respectively.
When a recess is provided and the first protrusion and the first recess are first engaged, the separation of the lid body and the molded product body, that is, the engagement of the first protrusion and the first recess is relatively small. By making it easy to release, the consumer can easily remove the lid from the molded product body when connecting a coaxial cable, and on the other hand, after the coaxial cable connection is completed, the second lid can be removed easily. By engaging the protrusion in the second recess, the molded product main body and the lid can be completely combined, and the two will not easily come off.
