Description

PCB Wiring Connector Terminal Block

The present invention relates to a wiring connector terminal block installed on a PCB (circuit board) of various electrical and electronic devices to easily connect electric wires. Is fixed to the PCB, and the outlet of the terminal block relates to a wiring connector terminal block for a PCB that is designed to be plugged into a plug after connecting an electric wire from the outside.

Conventional PCB grounding terminal block or wiring grounding terminal is installed in PCB with a fixed number of terminals to be grounded. Therefore, in order to cause trouble or add wiring, not only the whole wiring grounding terminal block needs to be replaced but also the terminal block. Its shape is large and occupies a lot of area to be installed on the PCB, and even though the wire grounding terminal is formed small, the body is formed in one piece that cannot be separated, and the wire is inserted into the through hole after installing the terminal on the PCB. It has to work to connect the ground to be grounded, but because the space is narrow, working on a complex and compact circuit board takes a long installation time and there was a problem inconvenient when working.

The present invention has been devised to solve such problems, and the PCB wiring terminal block is formed by separating the socket and the plug into a socket and a plug, respectively, and then the socket of the terminal block is formed of a powder metallurgy square terminal cap and a support clip. Internally and engaging pieces on both sides of the front body; A terminal piece with a ground pin is built into the terminal block plug, and a hooking jaw is formed at the top of the outer surface.In this invention, after installing the terminal block plug on the PCB (circuit board), the electric wire is connected to the outlet, and then the outlet is inserted into the plug. The terminal block to which the wire is wired is formed. This invention is designed to facilitate the wiring connection terminal block installation work, as well as shorten the working time and easy replacement and repair.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the wiring connection terminal block 2 provided on the PCB (circuit board) 1, a terminal clip 6 having a square terminal cap 5 made of powder metallurgy and a support piece 6 'is provided on the body 3a. The support piece 6 'in the rectangular terminal cap 5 is internally formed, and the outlet 3 is formed to be pressed against the bolt 8 pressed downward by the upper bolt hole 7 of the body 3a, and the outlet 3 is provided. A cover 11 having a through hole 11 'is fixed to the rear of the body 3a by a conventional ultrasonic bonding method, and a protrusion 3' having a plurality of terminal holes 14 is integrally formed on the front of the body 3a. Forming hooks 9 and 9 'on both sides of the protrusions 3',

An insertion groove 4a is formed to insert the protrusion 3 'of the outlet 3 and a plug 4 provided with a terminal piece 13 in the insertion groove 4a;

A ground pin 13 'is integrally formed at the end of the terminal flat 13 which is inserted into the terminal hole 14 of the protrusion 3' so as to protrude in the bottom direction of the plug 4,

The terminal block 2 is formed on the upper surface of the plug 4 so that the locking jaw 10 is formed to be caught by the locking pieces 9 and 9 'of the outlet 3 so that the outlet and the plug are coupled to each other.

The present invention configured as described above connects the electric wire 12 by installing a terminal block 2 as a means for supplying electricity to P.C.B circuit element lines installed in various electric and electronic devices. Therefore, the present invention first inserts and secures the ground pin 13 'of the terminal block 2 plug 4 to the PCB circuit line, and then attaches the power supply wire 12 to the terminal block outlet 3 body. (3a) through the cover (11) through the cover (11 ') fixed to the back by the ultrasonic bonding method in the back into the bottom of the support piece (6') located in the powder metallurgical square terminal cap (5), and then the outlet body (3a) When tightening the bolt (8) fitted in the upper bolt hole (7), the end of the bolt is lowered to press the support piece (6 ') so that the support piece (6') is firmly fixed to the wire 12 located at the bottom.

After connecting the electric wires 12 of several strands to the terminal block 2, the outlet 3, as described above, and inserting the terminal block plug (4) having a projection (3 ') formed with a plurality of terminal holes (14) on the front surface When it is inserted into the groove 4a, the terminal piece 13 located in the insertion groove 4a passes through the terminal hole 14 of the protrusion 3 'and is inserted into the terminal clip 6, and at the same time, the upper surface of the plug 4 is caught. In the jaw 10, a catching piece 9 (9 ') formed integrally so as to be slightly spaced apart on both sides of the front protrusion 3' of the outlet 3 body 3a is slightly opened by its repulsive force and returned Therefore, the outlet 3 and the plug 4 of the terminal block are firmly coupled as shown in FIGS. 1 and 4.

In addition, as another embodiment of the present invention, the ground pin 13 'installed to protrude from the plug 4 of the terminal block may be directed to the bottom surface as shown in Figs. 1 to 4, but according to the installation environment as shown in Fig. 5 The ground pin 13 ′ may be manufactured to protrude toward the rear surface of the plug 4 so as to be parallel to the terminal piece 13.

The present invention made as described above is designed to be connected to the circuit board (PCB) of the electrical and electronic devices as the number of wiring as shown in Figure 3, the form of the terminal block selectively from the 2-pin terminal block to more than 10 pin terminal block You can connect and use it. The square terminal cap used in the present invention is not a bent form of existing metal pieces, but a terminal cap formed by metal powder metallurgy such as bronze, brass, and copper. This prevents bad connection.

The wire connection terminal block made of the outlet and plug according to the present invention as described above is manufactured in a smaller size than the conventional terminal blocks of the first or second stages, thereby reducing the weight and volume and requiring a small installation area. Since the weight is small, the circuit board itself can be reduced in weight, and in case of breakage or poor contact, only the corresponding part can be partially replaced and the rest can be used as it is, thereby reducing the cost. In addition, the present invention installs the terminal block by installing only the plug part of the terminal block on the circuit board and inserts the plug into the plug insertion groove after grounding the wires in the other outlet part. And it is easy to work and has the effect of having a competitive product.
