I took the method of connecting the pipe after separating it by applying an impact. In that case, since the connection hole has already been formed in the terminal box, it is difficult to work only in one direction in a narrow space during on-site construction. Various difficulties such as the problem of internal leakage occurred.

So, in the improved invention, a cylindrical inner connector is provided on one side of the household terminal box, the external connector corresponding to the connection port is double coupled, and a tube is inserted into the external connector and an external power line and a communication line are connected. After doing this, it was mounted on the body of the terminal box, but the fixed form of the inner connector still has difficulties in on-site construction as in the previous invention. Due to the large number of surfaces, it revealed a problem of vulnerability to water leakage. In addition, when the pipe was inserted into the connector, there was no or weak fixing function, so the pipe was separated or damaged due to pressure during concrete pouring.

Accordingly, the pipe is easily combined with the household terminal box to achieve a solid bonding state so that the comprehensive purpose such as convenience of construction, shortening of work time, increase of durability, reinforcement of waterproofing safety, and convenience of maintenance can be simultaneously resolved. , there is no risk of leakage, and it is necessary to develop a household terminal box that has a detachable structure that is easy to construct on site and perfectly waterproof.

The other side of the outer cover 300 may cover both side ends of the frame 100 and both sides of the frame 100 while being in contact with one side of the inner cover 200) by a predetermined length, and on one side of the outer cover 300 In a position opposite to the internal connector 210 , a plurality of external connector 310 in a shape corresponding to the internal connector 210 may be erected to a predetermined length to form a plurality of rows and columns.

The outer cover 300 is mounted on the inner cover 200 while facing the outer connector 310 to the inner connector 210, the inner connector 210 is accommodated in the outer connector 310, the inner peripheral surface is mutually coupled, the outside The diameter of the connector 310 is formed larger than the diameter of the internal connector 210, and after the coupling is completed, a coupling gap 500 is formed as a gap space between the inner peripheral surface of the external connector 310 and the outer peripheral surface of the internal connector 210. can be

It is preferable that the width of the coupling gap 500 corresponds to the thickness of the corrugated pipe 600 and is formed at a level where the corrugated pipe 600 can fit and be inserted.

At this time, the corrugated pipe 600 is a pipe body that provides a passage for the electric power and communication cable drawn from the outside to be drawn into the frame 100, and is made of a plastic material having a predetermined elasticity and high strength or any material having similar characteristics. A general corrugated pipe 600 in which a plurality of corrugations are continuously and densely formed like concentric circles horizontally in the longitudinal direction of the tubular body may be used on the outer circumferential surface and the inner circumferential surface.

When the outer cover 300 is mounted on the inner cover 200) and the frame 100, the other side of the outer cover 300, that is, the other side of the front cover end 330 is the inner cover 200). In close contact with one side, the external connector 310 accommodates the internal connector 210 and is closely arranged, and both side ends of the outer cover 300 bent in a U-shape, that is, the side cover end 340 is the frame 100. A predetermined length surrounds both sides of one side of the .

Since the frame 100 has an upper end and a lower end extending a predetermined length forward, when the outer cover 300 is mounted, the side cover end 340 is also fitted inside the upper and lower edges of both sides of the frame 100. can be settled.

At this time, at both side ends of the other side of the front cover end 330, a step joint surface 331 may be formed in a stepped shape corresponding to the step 220 formed by the inner cover 200), and the step joint surface 331 may be formed. The other side of the outer cover 300 is closely coupled without a lifting space between the inner cover 200) and the frame 100 while being custom-coupled to the step 220 in a step shape, and since it is coupled in a stepwise manner, multiple bonding surfaces support can be secured.

And a drain end 341 in which a groove is formed along the longitudinal direction may be formed on the inner side of the side cover end 340, between the outer cover 300 and the inner cover 200) or between the frame 100 and the inside and outside. If there is water seeping into the gap between the covers 200 and 300 , it may be guided to the drain end 341 and discharged to the outside of the frame 100 along the drain end 341 .

The drain end 341 may also be formed with a groove on the outer surface of the side cover end 340, and may be formed in multiple numbers as needed, from one side of the front cover end 330, that is, from the outer surface to the side cover end 340. It may be formed in a section leading to

As a result, the household terminal box 10 with excellent coupling and waterproof performance of the present invention is smoothly drained to the outside of the frame 100 through the drainage end 341 of the outer cover 300, and leakage into the frame 100 is blocked. It can exhibit excellent waterproof function.

Meanwhile, as a major feature of the present invention, the fixing protrusion 400 may be formed on both the internal connection hole 210 and the external connection hole 310 .

The fixing protrusion 400 surrounds the outer circumferential surface of the inner connector 210 and protrudes vertically to face the coupling gap 500 , and in the external connector 310 , surrounds the inner circumferential surface and vertically protrudes to the coupling gap 500 . ) can be formed to face.

The fixing protrusions 400 formed on each of the internal connector 210 and the external connector 310 form a circular rim and are formed horizontally in the longitudinal direction of each connector, each of the internal connector 210 and the external connector 310 The fixing protrusions 400 formed on the are configured to be spaced apart from each other by a predetermined interval so as not to overlap each other, and as a preferred embodiment, the fixing protrusions 400 formed on the inner circumferential surface of the external connection port 310 are disposed on the upper side, and the internal connection port 210 ), the fixing protrusion 400 formed on the outer circumferential surface may be disposed on the lower side, and therefore, when the corrugated pipe 600 is inserted into the coupling gap 500, the insertion proceeds through the external connection port 310 and the fixing protrusion 400. and the inner connection port 210 comes close to the lower end and is coupled to the inner connection port 210 and the fixing protrusion 400 .

In this case, the outer peripheral surface of the corrugated pipe 600 is fitted to the external connector 310, the fixing protrusion 400, and the inner peripheral surface of the corrugated pipe 600 is fitted to the internal connector 210, the fixing protrusion 400, the corrugated pipe 600. Among the parts overlapping the external connector 310 and the internal connector 210 , the upper part is fixed by the external connector 310 fixing protrusion 400 , and the lower part is fixed by the internal connector 210 fixing protrusion 400 .

Therefore, the corrugated pipe 600 has a plurality of support couplings in which the inner and outer circumferential surfaces are supported at the same time, and the upper and lower portions of the corrugated pipe 600 are supported at the same time, so that a firm and stable fixed state can be achieved and can be prevented from being separated.

In addition, since the corrugated pipe 600 is mounted as a coupling gap 500 between the internal connection port 210 and the external connection port 310, water flowing in the direction of the frame 100 along the outer circumferential surface of the corrugated pipe 600 is the internal connection port 210 ) is blocked, so the waterproofness to the inside of the frame 100 can be maximized.

Meanwhile, the fixing protrusion 400 may be formed differently according to the first embodiment and the second embodiment.

The first and second embodiments of the fixing protrusion 400 are as shown in FIG. 4 , and FIG. 4 shows that the fixing projection 400 is fitted between the corrugations of the corrugated pipe 600 in each embodiment. It is a cross-sectional view showing the previous state.

The fixing protrusion 400 as the first embodiment vertically protrudes toward the coupling gap 500 in each of the internal connection ports 210 and the external connection ports 310, and from one end attached to each connection port toward the coupling gap 500. It may be in a form that becomes thinner toward the tip.

In this case, the fixing protrusion 400 may have various shapes including a cylinder, a cone, and a polyhedron, and preferably, one end has a relatively thick cylindrical shape and becomes thinner toward the other end to form a cone shape.

The fixing protrusion 400 may be composed of a protrusion support part 401 and a protrusion fitting part 402, and as one end attached to the connector, the protrusion support part 401 is made of a thick and rigid material to maintain a solid coupling state and at the same time Resistance to pouring concrete pressure can be secured, and when the corrugated pipe 600 is mounted, it functions to firmly maintain the shape and position without bending.

On the other hand, as the tip of the fixing protrusion 400, the protrusion fitting part 402 is formed of a thin and elastic material, and while being swept by the corrugated pipe 600, it can be bent at a predetermined angle according to the moving direction of the corrugated pipe 600, so when the corrugated pipe 600 is inserted. Easy coupling can be made, and when the coupling is completed, the fixing protrusion 400 is fitted into the corrugated pipe 600 between the wrinkle and the wrinkle T2, thereby achieving a stable fixation state.

At this time, preferably, the stone fitting portion 402 is thinned, but maintains a flat state in the direction of the lower end of the connector, and becomes thinner while being inclined in the direction of the upper end of the connector. It is easy to mount while meeting, and once the mounting is completed, the flat surface of the fixing protrusion 400 is in close contact with the corrugation of the corrugated pipe 600 horizontally, so movement in the opposite direction may be limited. Therefore, it is easy to put on, and once it is put on, it does not come off easily.

In this case, the length L1 of the fixing protrusion 400 is preferably formed to be longer than the depth T1 of the valley of the corrugated pipe 600 .

This is due to the reason that the diameter of the corrugated pipe 600 can be formed differently, if the corrugated pipe 600 having a small diameter is inserted and the length L1 of the fixing projection 400 is short, the fixing projection 400 This is because the fixing effect of the corrugated pipe 600 is inevitably reduced, and even if the corrugated pipe 600 with a small diameter is inserted, the fixing protrusion 400 is long enough, so the corrugated pipe 600 can be fitted into the fixing protrusion 400 . there will be

Conversely, even if the corrugated pipe 600 with a large diameter is inserted, the tip of the fixing protrusion 400 has elasticity and is thinly formed. ), even if longer than the depth T1 of the valley, the thin and elastic protrusion fitting portion 4020 may be inserted in a bent state in the space T2 between the wrinkles of the corrugated pipe 600 .

Therefore, the fixing protrusion 400 according to the first embodiment is mounted on the corrugated pipe 600 having various diameters while maintaining the coupling fixed state, so that it can have high utilization.

As the next second embodiment, the fixing protrusion 400 vertically protrudes toward the coupling gap 500 from each of the internal connection ports 210 and the external connection hole 310, and surrounds the edges of each connection port 210 and 310 and is a circular shape. is arranged in the shape of , and the overall shape such as upper and lower positions arranged at each connection port is similar to that of the first embodiment.

However, the fixing protrusion 400 of the second embodiment may be composed of a protrusion one end 410, the other protrusion end 420 and an elastic support 430, and the protrusion end 410 is a pillar at one end in contact with each connector. is provided in the shape of, and the other protruding end 420 is provided in a spherical shape at the other end facing the coupling gap 500 , and the elastic support 430 is a predetermined connecting protrusion end 410 and the other protruding end 420 . It may be provided in the shape of a long wire.

One end of the protrusion 410 is attached to the connector to maintain a solid support state, and the other end 420 of the protrusion acts as a part to be fitted between the wrinkles of the corrugated pipe 600 according to the insertion of the corrugated pipe 600, The elastic support 430 may be configured in a wire shape having a predetermined elasticity, so that when pressure is applied while the other protrusion end 420 is sandwiched between the wrinkles according to the insertion movement of the corrugated pipe 600, the elastic support 430 is It is bent in the direction in which the pressure is applied, and since the one end of the protrusion 410 is firmly supported, the elastic support 430 may also be bent in a predetermined angle range while maintaining the coupling position of the connector.

The diameter of the other protruding end 420 is preferably the same as or smaller than the width T2 between the wrinkles of the corrugated pipe 600, and the diameter of the other protruding end 420 is the width T2 between the wrinkles. If the value is exactly the same as the value, it may become too tight during insertion, so it may be difficult to install smoothly. On the other hand, if the difference between the diameter and the wrinkle width (T2) is large, it becomes loose in the section of the other protrusion end 420 and the wrinkle width (T2), making it difficult to install tight. because it can

At this time, the elastic support 430 may be formed to have a long length, even if the length (L2) of the fixing protrusion 400 is longer than the depth (T1) of the corrugated pipe 600, the elastic support 430 is the corrugated pipe (600). Since it can be bent in a L-shape while being sandwiched between the wrinkles (T2) according to the insertion, the fixing protrusion 400 can be coupled even if it is longer than the depth (T1) of the wrinkles.

This is supplemented by the fact that there may be some numerical error depending on the product because the internal connection port 210, the external connection port 310, the fixing protrusion 400, and the corrugated pipe 600 of the present invention are manufactured with a mold rather than precision processing. As a structure, the diameter of the other protruding end 420 is smaller than the width T2 between the wrinkles and even in a loose situation, since the elastic support 430 is long, the elastic support 430 is bent as if crumpled and the other end of the protrusion 420 and It is filled with the space between the wrinkles and the wrinkles together to compensate for the decrease in bonding force due to the numerical error to increase the adhesion state.

When the insertion and mounting of the corrugated pipe 600 is completed, the other protrusion end 420 is fitted between the corrugations (T2) of the corrugated pipe 600 while being fitted and the protrusion one end 410 is firmly attached to the connector. Therefore, the corrugated pipe 600 is firmly supported by the fixing protrusion 400 and can maintain the coupled state.

As described above, the fixing protrusion 400 is formed on the inner circumferential surface of the outer connector 310 and the outer circumferential surface of the inner connector 210 to form a circular edge on the upper and lower portions of the coupling gap 500, respectively, corrugated pipe 600 It can function to support the inner and outer sides of the corrugated pipe at a plurality of points at the same time, and since an elastic material is applied to the part in contact with the corrugated pipe 600, it can be bent at a predetermined interval depending on the insertion direction of the corrugated pipe 600, so it is easy to install. , once coupled, one end of the attached fixing protrusion 400 of each connector has a strong supporting force that is not easily separated while maintaining the coupling shape due to the effect of being firmly attached with a hard material.

However, since the fixing protrusion 400 can be bent not only in the insertion direction of the corrugated pipe 600 but also in the separation direction of the corrugated pipe 600, if the corrugated pipe 600 is to be removed according to specific needs after installation By pulling the corrugated pipe 600 by applying a strong force, it may have a property that can be separated.

Therefore, in the present invention in which the fixing protrusion 400 is formed, the insertion and installation of the corrugated pipe 600 is easy, and once the installation is completed, it does not fall out and is not easily separated to achieve a stable combined state. and maintenance.
