Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an intermediate connector used in radio-controlled car toys and the like, interposed between, for example, a power supply side connector and a controller side connector.

BACKGROUND ART In conventional radio-controlled car toys and the like, no intermediate connector is known which is interposed between the power supply side connector and the controller side.

Problems to be Solved by the Invention Various companies sell different types of connectors attached to the power supplies of radio-controlled cars, and these connectors can be roughly divided into the following two types. One of them is the terminal receiving hole 1 of the casing 1 as shown in Figure 5.
This is a connector (hereinafter referred to as A type power supply side connector) 3 in which cylindrical female terminals 2 are provided in a and 1b, respectively, and the others are terminal receiving holes 1a and 1b of a casing 1 as shown in FIG. These are connectors 5 (hereinafter referred to as B-type power supply side connectors) each having a rod-shaped male terminal 4 therein.

The A-type power supply side connector 3 has a pair of rod-shaped male terminals 7 in the recess 6a of the casing 6 as shown in FIG. 7. 8 is used, and the B type power supply side connector 5 is a controller side connector in which cylindrical female terminals 10 are respectively provided in the pair of left and right protrusions 9a and 9b of the casing 9, as shown in FIG. (hereinafter referred to as the B type controller side connector) 1
1 is now in use.

Therefore, A type controller side connector 8
cannot be used for B type power supply side connector 5,
In order to use the B-type power supply side connector 5, there was a problem in that the controller-side connector had to be changed from the A-type connector to the B-type connector.

This invention was made to eliminate the problem of replacing the connector on the controller side, and by interposing it between the A type controller side connector and the B type power side connector, the connector can be used as is. This type of connector can be used as a power supply side connector.

Means for Solving the Problem A pair of cylindrical female terminals and a casing to which the pair of cylindrical female terminals are attached form an intermediate connector, and one end side of the casing is connected to each cylindrical female terminal. The above B is branched into one end of the casing.
The convex portion 9 of the controller side connector 11 of the type
Protrusions similar to a and 9b were made, and these protrusions were fitted to the B type power supply side connector 5, and the other end (non-branch side) was fitted to the A type controller side connector 8. .

Effect When the intermediate connector of the present invention is attached to the A-type controller-side connector 8, the A-type controller-side connector 8 is provided with protrusions similar to the protrusions 9a and 9b of the B-type controller-side connector 11. If the convex portion is inserted into the B type power supply side connector 5, the A type controller side connector 8 and the B type power supply side connector 5 will be connected via the intermediate connector.

Embodiments Next, embodiments of the present invention will be described with reference to FIGS. 1 to 4. Reference numeral 21 denotes an intermediate connector of the present invention, and the intermediate connector 21 has a pair of cylindrical female terminals 22 and 23 made of a conductive material such as copper, and these cylindrical female terminals 22 and 23 are attached. It consists of a casing 24 made of an insulating material such as plastic. One end side of this casing 24 is branched for each of the cylindrical female terminals 22 and 23, and an eighth
B type controller side connector 11 shown in the figure
Convex portions 25 and 26 substantially similar to the convex portions 9a and 9b are provided. These protrusions 25 and 26 have different shapes (specifically, the protrusion 25 has a rectangular cross section, and the protrusion 26 has a The protrusions 25, 26 can be fitted into the terminal receiving holes 1a, 1b without changing the polarity. 24a and 24b are a pair of upper and lower split parts constituting the casing 24, and the two are screwed together with female terminals 22 and 23 made of metal pipes attached inside.

Further, 27 is a connector holder, and the connector holder 27 consists of an elastic tongue piece 27h having a locking claw 27a at the tip and a connector holding part 27c. It is attached to the controller side connector 8 of the type. When the A type controller side connector 8 is fitted to the B type power source side connector 5, the locking claw 27a provided at the tip of the elastic tongue piece 27b is connected to the B type power source side connector 5. It engages with the protrusion 5a to prevent it from coming off.

Therefore, according to the embodiment, the A type controller side connector 8 can also be used as the B type power side connector 5, and since both are reliably connected by the connector holder 27, the connectors will not come off each other even during vigorous driving. Never.

Effects of the invention By interposing the intermediate connector, it becomes possible to connect the power supply side connector and the controller side connector, which could not be connected in the past.
