Abstract

The present invention discloses a dust blocking structure of the modular jack to prevent foreign substances such as dust from entering the modular jack. The present invention is provided with a case having a plug insertion hole in the front of the modular jack to prevent dust or the like from entering the inside of the modular jack in the state that the modular plug is removed, the first, In the well-known thing which is provided with 2 shutters and opens and closes a plug insertion hole, the spring which elastically supports the 1st, 2nd shutter provided in the back surface of an electric plug insertion hole is provided.

Accordingly, the present invention is because the first and second shutters are elastically pressurized by the spring, so that when the modular plug is removed, the plug insertion hole is automatically blocked. Therefore, there is no need to cover with a separate cap and there is an effect that can more reliably prevent foreign matters such as dust from flowing into the modular jack.

Description

Dust Shutting Structure of Modular Jack

The present invention relates to a modular jack embedded in an inner wall of a building, and to a dust blocking structure of a modular jack embedded in an inner wall of a building for network installation in an office or home occupied in response to an information trend.

In general, communication between computers converts data into digital signals, transmits and receives data, and can be effectively utilized by utilizing a communication line provided indoors or in a premises. To this end, a modular jack is installed at an end of a communication line wired indoors or a premises, and a terminal is provided with a modular plug to be electrically connected to the modular jack.

However, since most of the modular jacks are exposed in an open state to the outside of the terminal part, dust and foreign substances in the air flow into the product, resulting in deterioration of the product due to poor contact.

In order to solve such a problem, as shown in FIG. 1, a case 200 in which a plug insertion hole 210 is formed is installed on a front surface of a modular jack 100, and a housing 300 is assembled on a rear surface thereof. In addition, the back of the case 200 is provided with a first shutter 400 and a second shutter 450 capable of blocking the plug insertion hole 210.

The first shutter 400 has guide protrusions 460 formed at both sides of an upper front side thereof, and a handle 470 is formed at the lower front side thereof. The second shutter 450 has guide grooves 460 formed on both rear surfaces thereof.

As shown in FIG. 1, the dust blocking structure of the conventional modular jack has a plug insertion hole of the case 200 as the first shutter 400 and the second shutter 460 slide on the rear side of the case 200. Block 210 to block the dust in the air flows into the modular jack 100.

However, since the dust blocking structure of the conventional modular jack does not automatically block the plug insertion hole 210 of the case 200 as shown in FIG. 2, external dust or foreign matter is introduced into the modular jack 100. Inflow. That is, since the first and second shutters 400 and 450 installed on the rear surface of the case 200 are blocked by the plug insertion hole 210 by simply moving the slide, the first and second shutters 400 and 450 may be moved by the flow of the modular jack 100. Two shutters 400 and 450 are slid and the plug insertion hole 210 is opened.

Therefore, the foreign matter such as dust is introduced into the terminal portion 110 of the modular jack 100 through the open plug insertion hole 210 has a problem that the connection state of the modular jack 100 is poor.

Another type of modular jack has a structure in which the first and second shutters are lowered due to their own load when the modular plug is removed, but this is smoothly lowered by the own load when foreign substances such as dust and moisture introduced during use are caught. This becomes impossible. Therefore, even when the modular plug is removed, there is a problem that the shutter function is paralyzed because the shutter does not descend.

It is an object of the present invention to provide a dust blocking structure of the modular jack to automatically close the shutter by the elasticity of the spring when the modular plug is removed by the elastic to solve this problem.

In order to achieve the above object, the present invention has a case in which a case having a plug insertion hole is coupled to a front surface of the modular jack, and first and second shutters are provided on the rear surface of the plug insertion hole of the case to open and close the plug insertion hole. The present invention proposes a dust blocking structure of the modular jack, characterized in that a spring is provided for supporting the first and second shutters installed on the rear surface of the electric plug insertion hole.

Accordingly, the present invention has an effect of automatically blocking the plug insertion hole of the case in the state in which the modular plug is removed to prevent foreign substances such as dust from flowing into the modular jack.

This invention is described in more detail with reference to the accompanying drawings as follows.

As shown in FIG. 3, the modular jack 500 of the present invention is largely composed of a housing 550, a modular jack 500, and a case 600, and are assembled to be detachable from each other. First, the modular jack 500 is assembled to the housing 550. The case 600 is detachably assembled to the front surface of the housing 550.

The case 600 is a plug insertion hole 610 is formed in the front center portion, the spring receiving groove 620 is formed on both sides of the back, each spring receiving groove 620, the upper and lower ends of the welding projection 630 ) Is formed.

In addition, a first shutter 700 and a second shutter 750 are installed on the rear side of the case 600 to automatically open and close the plug insertion hole 610. That is, spring support plates 710 are formed at both sides of the first shutter 700 to be accommodated in the spring receiving groove 620 together with the spring 850, and spring fixing protrusions 720 are provided in the respective spring support plates 710. Is formed to prevent the departure of the spring 850.

In addition, the first shutter 700 has guide protrusions 730 formed at both sides of the front upper portion, and a handle 740 is formed at the lower front portion. The second shutter 750 is formed with guide grooves 760 formed at both sides of the rear surface of the second shutter 750 so as to accommodate the guide protrusion 730, and is positioned on the front surface of the first shutter 700.

On the other hand, the spring receiving groove 620 is provided with a spring fixing plate 800 is to prevent the separation of the spring support plate 710 and the spring 850. That is, the welding protrusion coupling hole 810 is formed at the upper end and the lower end of the spring fixing plate 800, and is welded after being combined with the spring fixing protrusion 720 so that the spring support plate 710 and the spring 850 are separated from the outside. To prevent it.

Referring to the operation and effects of the present invention configured as described above in detail.

Referring to FIG. 3, the first and second shutters 700 are used to connect the modular plug MP.

Opening of 750 allows for connection. That is, when the first shutter 700 is moved by using the handle 740 of the first shutter 700, the first shutter 700 slides along the guide groove 760 of the second shutter 750. Since the second shutter 750 is also moved by the first shutter 700, the plug insertion hole 610 of the case 600 is opened.

In this state, the modular plug MP is connected to the terminal portion 510 of the modular jack 500 through the connection hole 610, so that the modular plug MP and the modular jack 500 are connected.

Meanwhile, when the modular plug MP is removed, as shown in FIG. 4, the first shutter 700 and the second shutter 750 are always automatically inserted into the plug insertion hole 610 by the elastic force of the spring 850. Since it blocks the foreign matter, such as dust is effectively blocked to flow into the terminal portion 510 of the modular jack 500 through the plug insertion hole 610.

The above-described embodiment is merely an example of a preferred embodiment of the present invention and is applicable to various communication cable connectors or jacks.

As described above, the present invention blocks the plug insertion hole of the case by the elastic pressing of the first and second shutters. Therefore, since the plug insertion hole of the case is always automatically cut off when the modular plug is removed, there is a very useful effect of more reliably blocking foreign substances such as dust in the air from entering the modular jack.
