Description

Wire connector having waterproof function and assembly thereof, method for constructing the assembly thereof and facility including the assembly thereof

[0001] The present invention relates to a wire connector for a streetlight having a waterproof function, and more particularly, to a wire connector for a streetlight having a waterproof function, in which a connecting portion formed by twisting exposed wires while removing wires from a streetlight is inserted into a central insertion hole of a connector cap, silicone of a silicone member connected to a silicone injection hole is supplied to an insert connecting portion according to the movement of a silicone housing so as to be tightly filled and solidified without any gaps in the connecting portion, and a cushion connecting portion formed between the insertion hole and the insert connecting portion is positioned at the center without being limited by the thickness of the wire, and then the flow of silicone leaking through the connecting hole is checked so as to seal the connector so as to achieve accurate waterproofing, thereby achieving waterproofing and dustproofing.

[0002] In general, when connecting cut wires in electronic products or electrical work, a part of the synthetic resin coating that covers the outside of the cut wire is peeled off, and the stripped part of the wire to be connected is twisted and connected, or a separate connecting member is used for connecting, and a shrink tube is used, or a silicone compound is first secured inside the screw cap, and then the twisted wire is inserted into the connector and rotated to be fixed.

[0003] As mentioned above, silicone is supplied from the rear to seal the stripped wire portion of the wire being connected, but air, etc. remains in the gap formed in the connected portion, so the silicone is not sealed, and the required complete waterproofing cannot be achieved. As the wire is a conductor through which current flows, there was a problem that accidents such as electric shock and short circuits occurred.

[0004] To solve this problem, in the past, insulating tape or shrink tube was used to wrap and insulate the area around the stripped wiring.

[0005] However, when covering in the above manner, there is the inconvenience of having to use a torch or lighter on the insulating tape or shrink tube for each stripped part of the wire, and as the insulating tape and shrink tube age over time, some parts may peel off, causing the wire to corrode or the waterproofing to be quickly lost, so there is a limitation in that it is vulnerable to waterproofing.

[0006] To overcome these limitations, domestic patent registration number 2130823 (registered on June 30, 2020) is a wire connection part having a cap shape with a sawtooth shape on the outer surface, and connecting the stripped portions of multiple wires to be connected inside by rotation into a twisted shape by a built-in metal insert; and

[0007] A hollow cylindrical shape, one side of which is integrally attached to the lower outer surface of the wire connection part, and the other side through which the plurality of wires to be connected are inserted, and a bonded heat shrink tube that shrinks when heated is included;

[0008] The above bonded heat shrinkable tube has a shrinkage ratio of 3:1 to 6:1,

[0009] The material of the outer surface is one of polyolefin (PO), polyvinylidene fluoride (PVDF), and polyvinyl chloride (PVC), and is crosslinked by radiation.

[0010] The material of the inner surface is formed of either an ethylene-vinyl acetate copolymer (EVA) adhesive or a polyamide (PA) adhesive, and is characterized in that it softens when heated and permeates between the plurality of wires to be connected.

[0011] However, these conventional waterproof wire connectors are composed of a connector body (10) into which a stripped portion of a wire can be inserted, an insert fastening portion (14) inside the connector body (10), and a wire connector that forms insulating and waterproof silicone.

[0012] These conventional wire connectors remove the ends of the wires to expose the wires, insert the twisted wire-shaped connection part into the inside of the connector body, and rotate it so that the twisted wires are twisted around the insert connection part and connected as one piece, thereby sealing the inside of the insert connection part with silicone supplied in advance, thereby achieving waterproofing and dustproofing.

[0013] However, this type of connector body has a defect in that it is easy to fall out because the bonding strength of the multiple wires is weak, or electrical problems such as short circuits, poor contact, and current leakage occur due to the ingress of foreign substances such as moisture or dust into the insertion hole.

[0014] In particular, there is an increased risk of the wire connector coming off due to loosening of the connected part of the wire due to external factors such as temperature changes and vibrations at the connected part of the wire.

[0015] Meanwhile, heat shrink tubing used for insulation of recently terminated wires has limitations in that it is difficult to secure a sufficient insulation layer due to its thin thickness, it is difficult to prevent damage due to external force or friction, and it is difficult to protect the wire connection part from moisture and humidity.

[0016] Additionally, there was a limitation that the flame retardancy rating was low, requiring the use of a torch or heat gun during shrinkage work.

[0017] And, there was a defect in that a connector composed of a connector body (10) was installed on a distribution board (230) located on a part of a main support (220) installed on the ground through a fixed support (210) such as a streetlight, and when the water level rises due to monsoon or heavy rain, etc., moisture penetrates into the inside of the connector, causing an electric shock accident due to submersion.

[0018] Accordingly, the applicant of the present invention has conceived a waterproof wire connector capable of insulating and sealing a wired wire by providing a silicone watertight solidification method that can securely finish the wire connection for the stripped wire portion of the wire inserted into the connector body and seal the unstripped portion of the wire in the connector body insertion hole, thereby preventing wire from falling out, corrosion due to contact with air and moisture, and moisture penetration.

[0019] Accordingly, the present invention has been devised to solve the above-mentioned conventional defects, and the object of the present invention is to prevent electric shock accidents by forming an air pocket in the insertion hole even if the waterproof wire connector is installed upright during the process of installing it in a necessary location such as a streetlight distribution board, even if it is submerged in water due to a rise in the water level.

[0020] Another object of the present invention is to achieve complete waterproofing by inserting a wire-shaped connection part formed by twisting a wire with the tip of the wire removed into a connector body, fixing it to an insert fastening part, and injecting silicone into a silicone injection hole to seal it.

[0021] Another problem solved by the present invention is to install a cushion connecting member at the tip of the insert fastening portion so as to accommodate various sizes of wires, to concentrate the flow of silicone to the center so as to improve watertightness with the wires, and to enable confirmation of the completion status of the work.

[0022] Another object of the present invention is to stably perform storage and injection of silicone by accurately moving forward a silicone housing for storing silicone in various ways.

[0023] The present invention relates to a streetlight structure in which a main support column having a distribution board formed on the lower side of an upper column to which crossbars having heads on one or both sides are connected is installed to waterproof wires of electric wires to a connector body.

[0024] A connector body having a silicone injection hole connected to an insert fastening portion in which a wire end is formed in a spiral shape inside an insert hole into which the exposed wire is twisted and formed by removing the tip of the wire, and a portion of the wire end and the wire are fixed in rotation;

[0025] A silicone housing that is connected to the above connector body and forms a silicone storage space in which silicone is stored and applies pressure to supply silicone to the insert fastening portion to make the connection portion waterproof;

[0026] It includes a cushion connecting member located in the above insertion hole and the fixing jaw of the insert fastening part, and having a connecting hole formed in the center to allow a wire to pass through and be connected.

[0027]

[0028] The present invention relates to a connector that is waterproof and is connected by supplying silicone to an insert fastening portion that is fixed in rotation by inserting a wire formed by twisting a wire with the tip of the wire removed,

[0029] The above connector includes a connector body, a silicone housing, a silicone member, and a cushion connecting member,

[0030] The above connector body includes an insertion hole, a fixing jaw, an insert fastening portion, and a bulkhead,

[0031] The above bulkhead is formed on one side of the connector body, and a silicone injection hole communicating with the insert fastening part is formed in the center of the bulkhead.

[0032] From the inside of the above bulkhead, the connector body forms a tapered insert fastening part with a screw formed to expand in the other direction,

[0033] It is formed so that the end of the covered wire is in contact with the minimum diameter side of the insert fastening portion, and can be inserted so that the unexposed part of the wire is in contact with the maximum diameter side of the insert fastening portion.

[0034] At the end of the maximum diameter of the above insert fastening part, an insertion hole having a diameter larger than the maximum diameter of the insert fastening part is formed, and a fixing jaw is formed due to the difference in diameter between the maximum diameter of the insert fastening part and the insertion hole.

[0035] The silicone housing is connected to the connector body and forms a silicone storage space where silicone is stored, and applies pressure to the silicone to supply it to the insert fastening portion to make it waterproof.

[0036] The above cushion connecting member has a circular hole formed in the center and is fixed to the fixing jaw.

[0037] The above hole is less than twice the diameter of the above wire, and the material is an elastic material that can be elastically expanded, so that the wire passes through the hole, and the silicone is exposed as a connecting hole, thereby providing a waterproof drain.

[0038] The permanent silicone housing includes a tubular silicone housing.

[0039]

[0040] The above connector body is characterized in that a wire is positioned in the insertion hole, silicone flows out through the connection hole to form a waterproof outlet, and an air pocket is formed in the insertion hole (11).

[0041]

[0042] The above insert fastening portion (14) is characterized by being formed as a conical hole and having a screw formed on the inner surface.

[0043]

[0044]

[0045] *The above insert fastening part is characterized in that the minimum diameter is smaller than twice the wire diameter, the maximum diameter is larger than twice the wire diameter, the slope is the same as the slope between the end of the wire and the end of the covered wire, and the depth is formed so that the wire can be inserted up to a part of the wire that is not exposed.

[0046]

[0047] The above connector body is characterized in that a silicone member for storing silicone is supplied to a silicone storage space connected to a silicone injection hole, and is connected to a press-type silicone housing that is connected to the silicone storage space and presses the silicone member to supply it to the silicone injection hole.

[0048]

[0049] The above connector body is characterized in that a silicone member for storing silicone is supplied to a silicone storage space connected to a silicone injection hole, and is connected to a tube-shaped silicone housing that is connected at a sealing part and presses the silicone member to supply it to the silicone injection hole.

[0050]

[0051] The above connecting member has a connecting hole formed in the center, is connected to a fixed jaw, has elasticity, and a wire passes through and is inserted into the insert fastening portion, and silicone flows out to maintain a waterproof function.

[0052] Accordingly, the present invention provides the effect of preventing electric shock by installing a waterproof wire connector so that it is erected during the process of installing it in a necessary location such as a streetlight distribution board, so that even if it is submerged in water or filled with water due to a rise in water level caused by rainy season, etc., an air pocket of a certain space is formed in the insertion hole to block the connection of electricity.

[0053] The present invention provides an effect of realizing complete waterproofing by inserting a wire formed by twisting a wire with the tip of the wire removed into a connector body, fixing it to an insert fastening portion, and then sealing it by injecting silicone into a silicone injection hole.

[0054] The present invention installs a cushion connecting member at the tip of an insert fastening portion so that all wires to be connected can be accommodated even when they are of various sizes, and concentrates the flow of silicone to the center to prevent water from seeping into the empty space between the wires, thereby improving watertightness and enabling the worker to directly check the completed state on site after performing the work, thereby providing the effect of improving the completeness of the work.

[0167]

[0168] Fig. 17 is a cross-sectional view of the body dimensions of one embodiment of the connector body and wire coupling of the present invention.

[0169] The insert fastening portion (14) is formed as a conical hole, and a screw is formed on the inner surface, the minimum diameter (2d1) of the insert fastening portion (14) is smaller than twice the diameter (d1) of the wire (21), the maximum diameter (2d2) of the insert fastening portion (14) is larger than twice the diameter (d2) of the wire (20), the inclination of the insert fastening portion (14) is the same as the inclination between the end of the twisted wire (21) and the end of the covered wire, and the depth of the insert fastening portion (14) is formed so that the twisted wire (21) can be inserted up to a part of the wire (20) that is not exposed.

[0170] An insertion hole (11) having a diameter larger than the maximum diameter (2d2) of the insert fastening portion (14) is formed at the end of the maximum diameter (2d2) of the insert fastening portion (14), and a fixing jaw (12) is formed due to the difference in diameter between the maximum diameter (2d2) of the insert fastening portion (14) and the insertion hole (11).

[0171] The slope of the insert fastening portion (14) is made the same as the slope of the wire (20) and the connection portion (22), and the depth of the insert fastening portion (14) is formed in a structure that allows the wire (20) to be inserted to a portion where it is not exposed, thereby reducing the amount of silicone to be injected, and the waterproof performance is improved by wrapping the tip of the wire (20) where the covering is not peeled off with silicone (42).

[0172]

[0173] Fig. 18 is a cross-sectional view showing a state in which an air pocket is formed by submersion in the insertion hole of the present invention.

[0174] In the process of removing a part of the wire (20) from the inside of a distribution board (220) of a streetlight (200) to expose the wire (21), and then connecting it to the connector body (10) at the connection part (22) and supplying silicone (42) to provide a waterproof function, the connector (100) is installed vertically with the insertion hole (11) positioned at the bottom so that it faces the upper side of the wire (20), thereby creating an air pocket (110) according to the formation of a vertical space at the tip of the insertion hole (11), thereby preventing water leakage and providing a waterproof function, and preventing electric shock accidents even in the event of flooding.

[0175]

[0176] The waterproof function streetlight wire connector of the present invention having such a configuration is formed by peeling off the outer covering of synthetic resin that surrounds two wires (20), twisting the exposed wires (21) to form a connection portion (22), holding the wires (20), passing the connection portion (22) through the insertion hole (11) of the connector body (10), passing through the connection hole (61) of the cushion connection member (60), and supplying it to the insert fastening portion (14), and then rotating the connection portion (22), so that the wire (21) is fixed while rotating to the insert fastening portion (14).

[0177] At this time, the cushion connecting member (60) inside the connector body (10) moves inward under the influence of the force applied in the direction of travel of the wire (20) and the wire (21), wraps around the outer diameter of the wire (20), and fixes it, and moves the wire (21) in a rotational manner to move along the spiral shape of the insert fastening portion (14).

[0178] After fixing the wire (21) to the insert fastening portion (14), the inner screw portion (31) of the silicone housing (30) is rotated while being coupled with the outer screw portion (13) to advance the coupling of the inner and outer screw portions (31, 13).

[0179] When the above silicone housing (30) is rotated and turned, the silicone member (40) in the silicone storage space (33) is pressed and compressed, and the injection port (41) of the compressed silicone member (40) is opened first, and the silicone (42) stored inside flows through the opened injection port (41) and into the insert fastening portion (14) from the silicone injection hole (15).

[0180] The silicone (42) injected into the above insert fastening portion (14) finds and fills the empty space of the twisted wire (21), and completely fills the inner insert fastening portion (14) of the cushion connecting member (60) so that no empty space due to air is created, and while supplying pressure to the cushion connecting member (60), pressure is provided around the connecting hole (61) to move it partially outward, and at the same time, the silicone (42) moves into the space formed on the outer diameter of the wire (20) through the connecting hole (61), so that, as shown in FIGS. 8 and 18, the leaked silicone (42) wraps around the wire (20) like a waterproofing outlet (43) and seals it so that no empty space with air is created.

[0181]

[0182] The above cushion connecting member (60) has elasticity (cushion) of rubber material, so that it moves inward and deforms when the wire (20) is connected, and even if the connecting hole (61) does not exactly match the thickness of the wire (20), it can accommodate a certain thickness, so that there is no restriction on the wrapping thickness and it can provide a fixed position in the center.

[0183] The pressure of the silicone (42) supplied through the insert fastening portion (14) causes the periphery of the connecting hole (61) to move in the direction of the wire (20) and be deformed, and a portion of the silicone (42) flows out into the connecting hole (61) to form a waterproof outlet (43).

[0184] In addition, the silicone (42) supplied to the insert fastening portion (14) is precisely sealed so that no air space is created in the wire (21), the wire (20), and the insert fastening portion (14) by the rotational pressure of the supplied silicone housing (30), and is exposed to the outside through the connecting hole (61) of the cushion connecting member (60) and wraps the wire (20), thereby providing concentrated watertightness at the location (center) where the wire (20) is installed, and the state of being fastened so that watertightness is accurately provided can be confirmed with the naked eye.

[0185] The above wire (20) is connected regardless of whether it is covered or not, from the insert fastening portion (14) and insertion hole (11) of the connector body (10) to the wire (21) and connection portion (22), and then is sealed through silicone (42) without air inflow to a certain section outside the cushion connecting member (60), and when dried, it provides a process of becoming completely waterproof.

[0186] As the silicone hardens, it provides complete waterproofing, and prevents the connection part (22) from being separated from the connector body (10) due to vibration or shaking due to weather or movement, and prevents corrosion of the space of the insert fastening part (14) and the wire (21) by stably providing waterproofing.

[0187] The fixing jaw (12) located between the above insertion hole (11) and the insert fastening portion (14) is generated by the difference in diameter between the end of the insertion hole (11) and the maximum diameter portion (2d2) of the insert fastening portion (14), and is formed on the inside of the connector body (10). Therefore, when waterproofing the connection portion (22) of the wire (20), an irregular waterproof discharge portion (43) is inevitably formed, but it is surrounded by the insertion hole (11) of the connector body (10) and is not visible. Therefore, even if the waterproof discharge portion (43) is irregular, a separate removal process is unnecessary, so work efficiency is increased.

[0188]

[0189] As shown in FIGS. 9a, 9b, and 9c, the present invention forms a connection portion (22) by stripping off the outer covering of synthetic resin surrounding two wires (20), twisting the exposed wires (21), and holding the wires (20), supplying the connection portion (22) through the insertion hole (11) of the connector body (10), the connection hole (61) of the cushion connecting member (60), and the insert fastening portion (14) while rotating the connection portion (22) so that the wires (21) are fixed while rotating in the insert fastening portion (14).

[0190] When the push-type silicone housing (30a) and the pressure protrusion (33a) protruding from the connector body (10) are slowly pressed with a finger, pressure is applied to the silicone member (40) as it moves to the silicone storage space (33), so that the silicone (42) moves to the insert fastening portion (14) through the silicone injection hole (15) and fills all internal spaces of the insert fastening portion (14), including the fixed wire (21) and the connection portion (22), so that no air space remains, and the silicone (42) that flows out like the waterproof discharge portion (43) through the connection hole (61) of the cushion connection portion (60) wraps around the wire (20) and seals it so that no empty space with air is created.

[0191] The above silicone injection hole (15) is located in the center of the bulkhead (16) and pushes out all air remaining in the insert fastening portion (14) to the outside, thereby enhancing the waterproof function.

[0192]

[0193] As shown in FIGS. 10a, 10b, and 10c, the present invention forms a connection portion (22) by stripping off the outer covering of a synthetic resin covering two wires (20), twisting the exposed wires (21), and holding the wires (20), passing the connection portion (22) through the insertion hole (11) of the connector body (10), passing through the connection hole (61) of the cushion connecting member (60), and supplying it to the insert fastening portion (14), thereby rotating the connection portion (22) so that the wires (21) are fixed while rotating to the insert fastening portion (14).

[0194] When the tubular silicone housing (30b) connected to the sealing portion (34) in the connector body (10) is slowly pressed from various directions, pressure is applied to the silicone storage space (33), so that the stored silicone (42) moves to the insert fastening portion (14) through the silicone injection hole (15) and fills all internal spaces of the insert fastening portion (14), including the fixed wire (21) and the connection portion (22), so that no air space remains, and the silicone (42) that has leaked out like the waterproof discharge portion (43) through the connection hole (61) of the cushion connection member (60) wraps around the wire (20) and seals it so that no empty space with air is created.

[0195]

[0196] As shown in FIGS. 11a and 11b, the present invention is to insert a part of a wire (20) and a connection part (22) made of a wire (21) into a connector body (10) so that the wire (21) is fixed to the insert fastening part (14) by rotation, and the outlet (35) of the silicone housing (30) is connected to the silicone injection hole (15) so that the pressing part (37) is slowly pressed so that the pressing part (36) moves and applies pressure, so that the stored silicone (42) moves to the insert fastening part (14) through the silicone injection hole (15) and fills all the internal spaces of the insert fastening part (14) including the fixed wire (21) and the connection part (22) so that no air space remains, and the silicone (42) that flows out like a waterproof discharge part (43) through the connection hole (61) of the cushion connecting member (60) wraps around the wire (20) and seals it so that no empty space with air is created.

[0197]

[0198] As shown in FIGS. 13 and 14a and 14b, the cushion connecting member (60) has cut lines (63) formed at narrow intervals along the periphery of the connecting hole (61) formed in the center so that the process of inserting the wire (20) into the connecting hole (61) can be easily performed, and the deformation action of opening easily so that the wire (20) of various thicknesses can be easily performed so that the wire (20) of various thicknesses can be accommodated, and after the wire (20) is inserted, the cut lines (63) wrap around the wire (20) with almost no space between them, and at the same time, the movement of the silicone (42) supplied from the direction of the insert fastening portion (14) is smooth, thereby stably providing a waterproof function.

[0199]

[0200] The present invention has a screw connection shaft (13a) formed on the outside of a silicone injection hole (15) formed at the tip of a connector body (10), as shown in FIGS. 15a and 15b, and a screw connection port (13b) that is screw-connected, and a toothpaste-shaped silicone housing (30d) storing a silicone member (40) inside is formed in a tube shape and screw-connected, thereby enabling convenient work through joining and separating of the toothpaste-shaped silicone housing (30b). The toothpaste-shaped silicone housing (30d) stores toothpaste in a tube shape, and through a process of squeezing, the stored silicone member (40) can be easily supplied from the silicone injection hole (15) to the insert fastening portion (14) through the screw connection shaft (13a) in the inner diameter of the screw connection port (13b).

[0201]

[0202] As illustrated in FIG. 16, the present invention is to insert the connection part (22) into the insert fastening part (14) and fix it by rotation, and then, when the air hole (39) of the pressurized silicone housing (30c) is blocked and the pressing cushion part (39a) is pressed, an air layer is formed between the connection part and the blocking film (38), and this air layer provides pressure to push the silicone (42) toward the silicone injection hole (15). When the pressure can no longer be provided to the silicone (42), the blocking film (38) moves inward by the amount of the pressure initially provided, and the space becomes larger. Therefore, the air hole (39) is opened to allow air to flow in, and the air hole (39) is blocked again to press the pressing cushion part (39a). This process is repeated so that the silicone (42) stored inside the silicone housing (30) passes through the insert fastening part (14) and the connecting hole (61) through the silicone injection hole (15) and is then supplied, thereby sealing the connection part so that no empty space with the air is created.

[0203]

[0204] The present invention, as illustrated in FIG. 18, is to perform the arrangement of the connector body (10) in the wiring section of the streetlight (200) and then perform the installation and finishing so that the tip of the insertion hole (11) faces downwards to connect the wire (20) and the wire (21) faces upwards, so that some of the silicone (42) leaks out of the insertion hole (11) to make it waterproof, and even if water gets in due to a typhoon or monsoon, an air pocket (110), which is an air pocket, is formed in the insertion hole (11) around the waterproof outlet (43) to block the inflow of water, thereby providing a waterproof function for the wire (20) and the wire (21) and providing the effect of preventing safety accidents such as electric shock.

[0205] The present invention provides a very useful invention in which a connector body is supplied with a wire and a wire connection part, and the wire is fixed to an insert connection part by rotation, and then a silicone housing is supplied to the insert connection part in various forms such as a rotation type, a pressing type, and a tube type, so that the silicone is filled to prevent air space from occurring between the connection part and the insert connection part, and the silicone is exposed to the outside through a cushion connection member to wrap around the wire and cool, thereby allowing the accuracy of the waterproof connection to be confirmed with the naked eye.
