Description

TECHNICAL FIELD The present invention relates to an electric terminal block connector, and more particularly to an electric terminal block connector including first and second connectors.

(Prior Art) Conventionally, in general, this type of terminal block connector has a female contactor,
A first connector (terminal block body) having a screw for connecting a terminal of a device and an insulating block to which these are mounted, and a second connector having an insulating block to which a male contactor is mounted. (Header) and. The second connector is fixed to a printed wiring board, and the first connector is attachable to and detachable from the second connector.

(Problems to be Solved by the Invention) The insulating block of the second connector needs to be formed with a sufficient thickness in order to reliably hold the male contact. This inevitably increases the overall height dimension of the terminal block connector, and cannot meet the demand for light, thin, short and compact terminals of this type.

Further, since the female contactor is generally formed of a thin metal plate having elasticity, it is not possible to engrave a spiral portion for screwing the screw. For this reason, it is necessary to attach a nut for screwing to a portion of the insulating block of the first connector into which the screw is screwed.

The object of the present invention is to form a first connector so as to hold the male contactor between two insulating blocks that fit with each other, and to embed the second connector therein. An object of the present invention is to provide a terminal block connector that can solve the above-mentioned problems by forming a fitting chamber that can be fitted and mounting the female contactor to the second connector.

(Means for Solving the Problems) In the present invention for achieving the above object, the first connector includes an insulating first block with which one end locking portion of the first male contactor engages, and (2) An insulating second block in which one end locking portion of the male contactor engages with the first block, and in addition, an intermediate portion of the first and second male contactors is the first and second blocks. And the other end contact portions of the first and second male contactors respectively face the fitting chambers formed in the first block. The second connector includes a female contactor that contacts each of the first and second male contactors on an insulative third block that is formed so as to be substantially buried in the fitting chamber and fitted therein. It is configured by being mounted.

In a preferred embodiment, one end locking portion of the male contactor is engaged with a groove formed in the first and second blocks, respectively, and an intermediate portion of the first and second male contactors is provided. The parts are respectively engaged with the concave grooves formed in at least one of the fitting surfaces of the first block and the second block.

Further, in a preferred embodiment, the first and second male contactors include a base portion, a locking portion extending from one side edge of the base portion, and a contact portion extending from the other side edge of the base portion. And a threaded portion formed on the base portion, and have the same dimensions.

(Operation) In the present invention having the above-described configuration, the first and second male contacts have the one-end locking portions engaged with the concave grooves of the first and second blocks, respectively, and the intermediate portion of the first and second male contacts. It can be fixed by interposing between the fitting surfaces of the two blocks.

A screw for connecting and fixing a terminal of the device can be screwed into a screwing portion formed on each base portion of the first and second male contactors.

When the second connector is fitted in the fitting chamber of the first connector,
The bottom surface of the second connector does not protrude from the bottom surface of the first connector. Therefore, the overall height of the terminal block connector is the same as that of the first connector.

As is clear from FIGS. 5 and 5, the upper surfaces of the first block 11 and the second block 21 are vertically stepped. It should be noted that the terminals of the device are interposed between the washer 37 and the base portions 12a, 22a of the first and second male contactors 12, 22 and tightened with screws 38 to electrically connect the device and the printed wiring board. Can be connected.

In FIGS. 10 to 14, the second connector 50 includes a third block 51 made of an insulating material and a plurality of female contacts 52 made of a conductive material.

The third block 51 has the same height as the first block.
A plurality of contact cavities that are substantially the same as the fitting chambers 28 of 11 and are formed so as to be buried and fitted in the fitting chambers 28, and open in the upper and lower surfaces and arranged in a zigzag pattern in the length direction. Has 53. A female contact 52 is mounted in each cavity 53. Each female contact 52 has a U-shaped cross section and has contacts on the inner surfaces facing each other. By the way, the shape of the female contactor 52 and the mounting means for the respective cavities 53 are known (Jitsuko Sho 58-29899).
(See the official gazette).

As shown in FIG. 15 (see FIGS. 4 and 5), the second connector 50 is fitted into the fitting chamber 28 of the first connector 10 and
The contact portions 12c and 22c of the second male contactors 12 and 22 are inserted into and contact the contact portions of the female contactors 52, whereby the first and second connectors 10 and 50 are connected. The legs of the female contact 52 projecting downward from the second connector 50 are connected and fixed to the printed wiring board.

This fitting state is achieved by screwing the screw 40 inserted into both flanges 29 of the second block 21 of the first connector 10 into the screw holes 42 provided in both flanges 41 of the second connector 50. It is designed to be fixed (Fig. 1, Fig. 3, Fig.
(See Figure 10).

(Effect of the Invention) According to the present invention having the above configuration, when the second connector is fitted in the fitting chamber of the first connector, the bottom surface of the second connector projects from the bottom surface of the first connector. Since the entire height of the terminal block connector is the same as that of the first connector, it is possible to meet the demand for a light, thin, short and compact terminal block connector of this type.

The one end locking portions of the first and second male contactors are respectively engaged with the recessed grooves of the first and second blocks, and particularly the intermediate portions thereof are respectively disposed between the fitting surfaces of the first and second blocks. By interposing it, the first and second male contactors can be sufficiently fixed and held on the first and second blocks (first connector).

Since a screw for connecting and fixing a terminal of a device is screwed into a screwing portion formed on each base portion of the first and second male contactors, a nut for the screw is used. do not need. Incidentally, unlike the female contactor, the male contactor has a large wall thickness, so that the screwing portion can be provided.

The first and second male contactors having the same size can be used, which is economical.
