Description

Technical Field

[0001] This invention relates to a connection device for power distribution lines, and more specifically, to a branch connection port for power distribution lines that connects multiple power distribution lines (i.e., branch lines) branching off from a main line. Background Technology

[0002] Under normal circumstances, during power distribution, the extra-high voltage of 22.9V is used as the distribution voltage and supplied to the main transformer at the power supply site. Then, the main transformer for power distribution converts it to low voltage of 220V or 380V and supplies it to ordinary households or industrial enterprises and other users with electricity needs.

[0003] A power distribution line branch connection joint is a device that branches a main line supplied as a package into multiple branch lines, used to connect multiple branch lines to the main line.

[0004] Regarding Korean Patent Registration No. 10-2460490 (published on October 31, 2022): A power distribution cable distributor for power distribution, comprising a housing having a main wire hole formed in the lower center for the main wire to be introduced, and a plurality of trunk wire holes formed at certain intervals around the main wire hole; a distribution means for electrically connecting the main wire to the trunk wire by external force, including distributing power supplied by the main wire to the trunk wire, wherein at least the end portion (Pa) of the distribution means is formed as a conductor and moves toward the main wire by the external force to contact the core wire of the main wire; a plurality of moving parts that contact the conductor portion (Pa) of the contact rod and move in a direction perpendicular to the moving direction of the contact rod; and a contact pin that protrudes from the moving material toward the trunk wire, including passing through the trunk wire housing and contacting the core wire of the trunk wire by the movement of the moving material, wherein the plurality of moving parts and the contact pin are characterized as being conductors.

[0005] According to the patent, by placing a distribution means inside a housing composed of conductors to distribute the power of the authorized main line to the trunk line, the risk of leakage caused by exposure of electrodes and connection points can be minimized.

[0006] However, this traditional technique requires fixing the position of the main cable (i.e., the main line) entry hole and the main cable (i.e., the branch line) entry hole, so that the entire distributor can be replaced if the main cable entry hole malfunctions.

[0007] In addition, in the past, because the direction of branch line introduction was fixed, the connection direction of branch lines was limited, making it difficult to easily connect branch lines approaching from different directions.

[0008] Furthermore, in the past, if any of the multiple branch lines overheated, this could not be detected in advance, thus failing to detect fire signs early and consequently failing to effectively prevent fires from occurring.

[0011] (Patent Document 1) Korean Patent Registration No. 10-2460490 (Published on October 31, 2022) Summary of the Invention

[0012] The problem that the invention aims to solve

[0013] Therefore, the present invention, having two or more cable terminals that can be combined with any one of the main line and branch lines, and a ring terminal that can simultaneously contact the two or more cable terminals, distributes the power of the main line to the branch line through the ring terminal, so that when any connection line connected to the main line or branch line fails, only the corresponding cable terminal is replaced, without replacing the entire device, thereby providing an easy-to-maintain branch line connection.

[0014] Furthermore, the present invention also aims to provide a branch connection port for power distribution lines by placing radially formed branch connection points on the annular terminal, which allows for free determination of the connection direction of the branch lines, thereby facilitating the connection of branch lines approaching from different directions.

[0015] Furthermore, the present invention also aims to provide a branch connection joint for power distribution lines, which, by having an overheat sensing component capable of detecting and displaying whether each branch connection port is overheated, can detect fire signs in advance, thereby effectively preventing the occurrence of fires.

[0016] means for solving problems

[0017] To achieve the aforementioned objective, the present invention provides a power distribution line branch connection connector, which distributes power supplied via a bus to two or more branch lines. The connector includes a first and a second annular connector; clamping grooves formed on both annular surfaces to clamp the first and second annular terminals respectively, forming a cylindrical terminal body that fixes the first and second annular terminals parallel at a predetermined interval; and, when combined with either the bus or the branch line, has two or more T-shaped cable terminals that, upon contact with the first annular terminal, have a rod end that contacts the second annular terminal and is mutually energized. The first and second annular terminals respectively feature radially formed contact protrusions with small openings protruding outwards from the terminal body, allowing one end or the rod end of the cable terminal to contact.

[0018] It is worth mentioning that the power distribution line wire branch connection joints are respectively installed on the contacts, including small-opening terminal pressure members that press the cable terminals crossing the contacts toward the contacts. The terminal pressure members are respectively received in the terminal body and moved in the direction parallel to the outer periphery of the terminal body by external force to press the cable terminals; and a pressure rod that is connected to the pressure rod and protrudes outward in the direction of the terminal body, which may include transmitting the external force applied to the outside of the terminal body to the handle of the pressure rod.

[0019] It is worth mentioning that the terminal body is formed at the position corresponding to the contact protrusion, with a small receiving space for accommodating the pressure rod and guiding the movement of the pressure rod; and a small boat guide ball extending from the receiving space to the outside of the terminal body, which may include guiding the movement of the handle.

[0020] It is worth mentioning that the power distribution line wire branch connection joint also includes multiple sheaths covering both sides of the terminal body, but the sheaths have a circular heat-sensitive seat attached to the inner side of the protruding boat handrail on the outside of the terminal body and the extended imaginary circle. The heat-sensitive seat can indicate whether it is overheated by the position of the overheating seat above a certain temperature in the boat handrail, according to the main line or the main line.

[0021] Invention Effects

[0022] According to the aforementioned provisions, the power distribution line wire branch connection joint of the present invention has the following advantages: two or more cable terminals that can be combined with either the main line or the branch line, and a ring terminal that can simultaneously contact the two or more cable terminals. The power of the main line is distributed to the branch line through the ring terminal. If any of the connecting lines connected to the main line or the branch line fails, the entire equipment is not replaced, only the corresponding cable terminal is replaced, thus facilitating maintenance.

[0023] Furthermore, an advantage of the present invention is that by placing radially formed branch line connection points on the annular terminal, the connection direction of the branch lines can be freely determined, thereby facilitating the connection of branch lines approaching from different directions.

[0024] In addition, the present invention also has an overheat detection component that can detect and display whether the inlets of each branch line are overheated, thereby detecting fire signs in advance and effectively preventing fires from occurring. Attached Figure Description

[0041] C: Cable Detailed Implementation

[0042] The embodiments of the present invention will now be described with reference to the accompanying drawings. However, this detailed description will allow those skilled in the art to readily implement the invention. The invention can be embodied in many different forms and is not limited to the embodiments described herein. Furthermore, for the purpose of clearly illustrating the invention in the drawings, parts irrelevant to the description have been omitted, and similar reference numerals have been added to similar parts throughout the list. Additionally, even when detailed descriptions are omitted, parts readily understood by those skilled in the art have also been omitted.

[0043] Within the entire list and the scope of the claim, if a section contains a certain component, it means that other components may be included, rather than excluding other components, unless specifically stated otherwise.

[0044] Figure 1 These are four views of a connection joint for branch wires in a power distribution line, according to an embodiment of the present invention. Figure 2 This is an exploded view of a branch connection joint of a power distribution line according to an embodiment of the present invention. Figure 3 This is a partial view of the terminal body that makes up the branch connection joint of the power distribution line according to an embodiment of the present invention.

[0045] like Figures 1 to 3 As shown, according to one embodiment of the present invention, the power distribution line wire branch connection port 100 may include first and second annular terminals (110 and 120), terminal body 130, cable terminal 140, terminal pressure member 150 and sheath 160 to distribute power supplied via the bus to two or more branch lines.

[0046] The first and second annular terminals (110 and 120), made of a conductive material, are fixedly mounted on the terminal body 130 and contact a plurality of cable terminals 140, electrically connecting the cables connected to each of the cable terminals 140. Notably, the first and second annular terminals (110 and 120) can simultaneously contact two or more cable terminals 140 (described later), thus allowing electrical connection of all cables without distinguishing between main and branch lines. That is, the first and second annular terminals (110 and 120) are suspended from one end 141 or the other end 142 of the cable terminals 140, respectively, and electrically connected to the cables connected to the cable terminals 140. For example, one end 141 of the cable terminal 140 is suspended on the first annular terminal 110, and one end 142 of the cable terminal 140 is suspended on the second annular terminal 120; the first and second annular terminals (110 and 120) can be electrically connected to the cables connected to the cable terminals 140.

[0047] Therefore, if the first and second branch lines are connected to any first and second cable terminals, the bus is connected to any other third cable terminal, and all of the first or third cable terminals are in contact with the first and second ring terminals (110 and 120), the power recognized by the bus may be branched to the first and second branch lines.

[0048] At this time, in order to make stable contact with the cable terminal 140 in the first and second annular terminals (110 and 120), small contact protrusions 111 and 121 at one end 141 of the cable terminal 140 or across the terminal 142 may be formed protruding outward in the direction of the terminal body 130 (described later). It is worth mentioning that the contact protrusions 111 and 121 may be formed radially.

[0049] The terminal body 130 is shaped like a cylinder or a circular plate of a specified thickness. Clamping grooves 131 are formed on the two annular surfaces of the cylinder or plate, into which the first and second annular terminals (110 and 120) are inserted, respectively, thus fixing the first and second annular terminals (110 and 120) parallel at a specified interval. It is worth noting that when fixing the first and second annular terminals (110 and 120), the contact protrusions 111 and 121 formed by the first and second annular terminals (110 and 120) should be positioned opposite each other. This is to ensure that one end 141 and one end 142 of a cable terminal 140 spans the opposing contact protrusions 111 and 121, thereby achieving stable contact.

[0050] On the other hand, the spacing between the first and second annular terminals (110 and 120) is determined based on the height of the cylinder or the thickness of the circular plate. This spacing can be determined by the distance between one end 141 of the cable terminal 140 and the strike 142, as described later. Alternatively, the distance between one end 141 and the end 142 of the cable terminal 140 can also be determined based on the spacing.

[0051] In addition, a certain number of receiving spaces 132 and guide holes 133 can be formed on the terminal housing 130. This is to guide the receiving and movement of the terminal pressure member 150, which will be described later. The receiving spaces 132 and guide holes 133 can be formed at the corresponding positions of the contact protrusions 111 and 121 formed on the first and second annular terminals (110 and 120).

[0052] The receiving space 132 accommodates the pressure rod 151 that constitutes the terminal pressure member 150 described later, and guides the movement of the pressure rod 151.

[0053] The guide ball 133 extends outward from the corresponding receiving space 132 toward the terminal body 130, guiding the movement of the handle portion 133 that engages with the pressure rod 151. It is worth noting that the guide rod 133 can be configured to limit the range of movement of the pressure rod 151, preventing the pressure rod 151 from directly contacting the inner surface of the contact protrusion (111 or 121), thereby damaging the inner surface (111 or 121).

[0054] In addition, a fixing protrusion may be formed at the end of the guide hole 133 (i.e., in the direction of the outer peripheral surface of the terminal body 130) to fix the position of the handle part 133. This is to fix the position of the handle part 133 so that the pressure rod 151 is kept in the pressure state corresponding to the cable terminal 140.

[0055] In addition, a cover connection port 134 can be formed in the center of the terminal body 130, which will be used for the cover 160 described later.

[0056] Cable terminal 140 is coupled to any cable (i.e., one of the bus or branch lines) and contacts the first and second ring terminals (110 and 120). For example, one end 141 of cable terminal 140 contacts the first ring terminal 110, and the cross end 142 contacts the second ring terminal 120. If two or more cable terminals 140 contact the first and second ring terminals (110 and 120), they can be electrically connected and energized to each other through the first and second ring terminals (110 and 120). For this purpose, cable terminal 140 can be formed in a T-shape, including one end 141 that contacts the first ring terminal 110, one end 132 that contacts the second ring terminal 120, and a coupling socket portion for coupling with the cable.

[0057] The terminal pressing member 150 is provided with a predetermined number of contact protrusions (111 or 121) corresponding to the predetermined number of contact protrusions, and the cable terminal is pressed into the contact protrusion direction through the corresponding contact protrusions. For this purpose, the terminal pressing member 150 can be respectively housed in the terminal body 130 (i.e., the receiving space 132), and the pressing rod 151 pressing the cable terminal 140 is moved parallel to the outer periphery of the terminal body 130 by external force, and the pressing rod 152 is combined with the pressing rod 151 on one side and protrudes outward of the terminal body 130 in the other direction, and the pressing rod 152 transmits the pressing rod 151 as external force on the outside of the terminal body 130.

[0058] Furthermore, the terminal pressure member 150 may also include a return spring 153, which, when the external force is released, restores the position of the pressure rod 151 back into the receiving space 132. For this purpose, the return spring 153 can be made of a spring material, with one side fixed to the inside of the receiving space 132 and the other side fixed to the inside of the pressure rod 151, so that the inside of the receiving space 132 and one side of the pressure rod 151 exert force in a direction of approach.

[0059] The cover 160 may include two sections covering the terminal body 130, a heat-sensitive seat 161 attached to the inner circular shape of the handle portion 152 of the small boat extending outward from the terminal body 130 and contacting the imaginary member extending to the other side, and a signing protrusion 162 on the cover connection port 134.

[0060] Thermistor 161 can detect and display overheating by displaying the position of an overheated handle in a given handle section 152 that has overheated to a specific temperature. In other words, thermistor 161 can detect and display overheating by color change based on the overheated cable terminal connected to any overheated main line or branch line, the overheated pressure bar pressurizing the overheated cable terminal, and the heat transferred through the overheated handle section connected to the overheated pressure bar.

[0061] The fastening protrusion 162 has an outer peripheral surface formed on the thread, which can be engaged with the thread formed on the inner peripheral surface of the covering fastening area 134 by thread fastening.

[0062] Figure 4 and Figure 5 This is a cross-sectional view illustrating the connection structure of the branch connection port of a power distribution line according to an example of the present invention. Figure 4 (a) indicates the state between the cable terminal 140 entering the interval of the first and second annular terminals (110 and 120). Figure 4 (b) indicates that the cable terminal 140 rotates between the intervals. Figure 1 The second ring 110 and the second ring (110 and the second ring) are respectively connected to the terminal 120 and the second ring terminal 120. Figure 5 The figure shows the connection state of the cable terminals (110 and 121), with the second ring and the second ring respectively. This indicates that the contact with the contact protrusions 111 and 121 is in a stable state.

[0063] like Figure 4 As shown in (a) and (b), the power distribution line wire branch connection connector of the present invention can be easily connected by rotating the cable terminal 140 in the cable connection state between the gap of the first and second annular terminals (110 and 120). On the other hand, the first and second annular terminals (110 and 120) have a certain elastic force due to the structural feature formed by the protruding contact protrusions 111 and 121 formed in the outer direction of the terminal body 130. This elastic force makes it easier to connect with the cable terminal 140. In addition, the impact exerted by the elastic force on the cable terminal 140 connected to the base may be partially alleviated.

[0064] like Figure 5 As shown, according to the external force applied to the handle 152 in the direction of the arrow, the pressure rod 151 will... Figure 4 The cable terminal 140, which is joined together with the first and second annular terminals (110 and 120), is pressed into the direction of the arrow shown in the figure, thus making firm contact with the contact protrusions 111 and 121 formed on the first and second annular terminals (110 and 120). At this time, the handle portion 152 can move along the guide hole 133 as shown in the enlarged view, and then settle into the fixing protrusion formed at the end of the guide hole 133, fixing its position. At this time, the return spring 153 provided in the receiving space 132 remains in a state of tension under the external force. If the handle portion 132 is separated from the fixing protrusion, this state is released, the tension of the return spring 153 is released, and the position of the pressure rod 151 can be restored.

[0065] Figure 6 and Figure 7 This describes the usage state of the branch connection port of a power distribution line according to an embodiment of the present invention. Figure 6 According to one embodiment of the present invention, multiple cables are connected to the branch connection port 100 of the power distribution line. Figure 7 This refers to the condition where one of the multiple cables becomes overheated, and the thermistor 161 at its location (A) is detected as discolored.

[0066] According to the aforementioned regulations, the power distribution line wire branch connection connector of the present invention, after having two or more cable terminals that can be combined with either the main line or the branch line, and an annular terminal that can simultaneously contact the two or more cable terminals, distributes the power of the main line to the branch line through the annular terminal. If any of the connecting lines connected to the main line or the branch line fails, the entire device is not replaced, only the corresponding cable terminal is replaced, thus possessing the characteristics of equipment maintenance.

[0067] Furthermore, a feature of this invention is that by placing radially formed branch line connection points on the annular terminal, the connection direction of the branch lines can be freely determined, thereby facilitating the connection of branch lines approaching from different directions.

[0068] In addition, the present invention also has an overheat detection component that can detect and display whether overheating occurs at the branch line connection, thereby detecting fire signs in advance and effectively preventing fires from occurring.

[0069] The embodiments of the present invention have been described above, but the scope of the present invention is not limited thereto. It includes all changes and modifications to the present invention from the embodiments onwards that are readily altered by a person of ordinary skill in the art to which the present invention pertains and are considered equivalent.
