Description

Bracket to combine Modular jack for asynchronous-type serial communications}

The present invention relates to a bracket for coupling and securing a multi-port modular jack (Modular jack) mounted on a printed serial circuit board (PCB) for an asynchronous serial communication port module, more specifically, to match the modular jack in the center of the bracket The present invention relates to a coupling bracket of an asynchronous serial communication modular jack capable of firmly fixing a modular jack by forming a square hole and forming bent portions at three inner sides thereof.

Modular jack is generally connecting terminal and indoor wiring, and is a communication port that can be separated and combined without using a tool such as a driver.

This modular jack is mainly used for asynchronous serial communication, which is mounted on a separate PCB and coupled to the PC main body by a bracket coupled to the front.

The bracket used for the PCB for the asynchronous serial communication port module described above has a rectangular hole for combining a jack and a modular jack indicating the operation state of a plurality of light emitting diodes, such as Utility Model Registration No. 0147338, filed by the applicant of the present invention. The formed bracket has been raised.

However, since a general personal computer uses one or two modular jacks such as a jack for a telephone line and a jack for an external line, only a hole enough to insert an electric modular jack into the bracket is fixed and used.

In the case of using the multi-port modular jack having multiple modular jacks, a gap occurs between the bracket and the modular jack, and the modular jack for the multi-port modular jack cannot be held firmly by the bracket. There is a problem that the jack is moved or loose, which adversely affects the contact failure and the PCB pattern.

In addition, EMI waves emitted from the modular jack adversely affect the PCB for the asynchronous serial communication port module. Such electromagnetic interference (EMI) generally refers to an electromagnetic signal being damaged by electromagnetic interference. In this case, high-precision electronic equipment mounted on the vehicle or operating in the vicinity due to unnecessary electromagnetic waves generated from the electrical equipment causes malfunction or malfunction. The process is that electromagnetic waves are transmitted through signals or power lines between the electronic equipment to share power. Conducted emission (CE), which affects each other's components, and radiated emission (RE), which is a phenomenon influencing the high-precision electronic equipment operating in the surrounding area by radiating electromagnetic waves generated from electrical equipment to space. Are distinguished.

The present invention eliminates the problems as described above, in the bracket for a conventional modular jack, to form a rectangular hole in which the multi-port modular jack is inserted in the middle portion, the bending extension portion on the upper and both sides of the rectangular hole By forming

The bending extension part makes sure contact with the panel ground part for preventing EMI wave emission, which is embedded in the modular port for multi-port, so that the electrical effect of blocking EMI emitted to the outside is prevented.

Modular jack for multi-port is more firmly fixed by the bending extension part, so there is almost no shaking or movement even when using the modular jack for a long time, and thus the asynchronous serial communication modular jack has a mechanical effect to prevent contact failure and damage to the PCB pattern. The purpose of the present invention is to provide a coupling bracket of.

Hereinafter, embodiments of the present invention will be described by the accompanying drawings.

1 is an overall perspective view of the bracket of the present invention, Figure 2 is an exploded perspective view showing a state of coupling the bracket of the present invention to the PCB for an asynchronous serial communication port module.

In the conventional bracket (3) formed with the bending coupling portion (1) (1 ') for PCB coupling and the bending portion (2) for PC body coupling,

The square hole 4 for the multi-port modular jack is formed in the middle of the bracket 3, and the guide parts 5 and 5 'are formed to be bent to one side and to the upper and left and right sides of the square hole 4, respectively. Thus, the panel ground 9 of the modular multi-port modular jack 6 is supported.

In the figure, reference numeral 7 is a PCB, 8 is a coupling bolt.

Referring to the operation of the present invention by the configuration as described above in more detail by the accompanying drawings as follows.

As shown in FIG. 2, the asynchronous serial communication port module PCB 7 is inserted into and operated in a slot (not shown) mounted on a separate main PCB, which is exposed to the outside on one side of the PCB 7. The multi-port all-jack 6 is formed.

In this state, when the bent coupling portion (1) (1 ') for PCB coupling formed on both sides of the lower side of the subject innovation bracket (3) and coupled to the PCB by the coupling bolt (8),

As shown in FIG. 3, the modular jack for multiport is inserted into the square hole 4 formed at the center of the bracket 3, and the guide parts 5, 5 ′ and the panel ground 9 are tightly supported. The ground plane is spreading.

Therefore, since EMI waves emitted from the inside of the modular jack 6 are prevented from being emitted to the outside by the expanded ground plane, the PCB for the asynchronous serial communication port has little harmful interference.

Figure 4 is a cross-sectional view showing the bending portion (1) (1 ') for PCB coupling of the bracket (3) in the state that the multi-port modular jack (6) is coupled, the bracket placed on the PCB (7) (3) is firmly fixed by inserting the coupling bolt (8) from the bottom of the PCB.

In addition, Figure 5 is a cross-sectional view showing a state in which the bracket 3 and the multi-port modular jack (6) of the present invention is coupled, inside the square hole (4) of the bracket (7) coupled to the PCB (7) One side of the multi-port modular jack 6 is inserted, and the multi-port modular jack is formed by the upper side and the guide portions 5 and 5 'formed on both sides of the square hole 4 inside the bracket 3. It is pressing-supporting the panel ground 9 of (6).

Accordingly, the multi-port modular jack 6 soldered and fixed to the PCB 7 is firmly fixed by the PCB 7 coupling operation of the bracket 3 of the present invention, and the present invention bracket 3 is coupled to the PC body. ) Is to prevent the multi-port modular jack (6) from being shaken or shaken, even if the communication line is connected and short-circuited from the outside for a long time to adversely affect the bad contact and PCB pattern.

Since the coupling bracket of the asynchronous serial communication modular jack of the present invention as described above is more firmly fixed to the multi-port modular jack by its bending extension, it blocks the emission of EMI waves emitted from the inside of the modular jack, There is almost no shaking or movement even if you use it to prevent contact failure and damage to the PCB pattern.
