Description

Technology Field

[0001] The present invention relates to a bidirectional joint connector, and more specifically, to a bidirectional joint connector that improves wiring workability by fixing the position of a recept terminal of a first wiring inserted into one side of a housing and a tap terminal of a second wiring inserted into the other side of a housing in a mutually connected state by a position fixing guide. Background Technology

[0003] Recently, as carbon energy is gradually depleting and environmental concerns are rising, the world, including the United States, Europe, Japan, and Korea, is focusing its attention on hybrid and electric vehicles.

[0004] Hybrid and electric vehicles use higher voltage and current compared to conventional vehicles, so they require electrical devices to stably supply and distribute power from the outside to internal components. In addition, many components are manufactured in modular form for the electronic control of the vehicle, and the use of wires and communication lines connected with connectors to transmit current or electrical signals has increased rapidly.

[0005] These joint connectors are used to electrically connect automotive parts, and they undergo various safety inspections to ensure that no electrical defects occur when mounted on the parts.

[0006] In addition, joint connectors connect multiple circuits with the same function to a single connector, allowing them to be fixed to the vehicle body or the main wiring.

[0007] Meanwhile, if a branch line is created from the main wiring during the wiring installation process, a separate joint connector is added to connect the branch line.

[0008] However, the joint connector of the prior art configured in this way has a small number of connection pins connected to the wiring, so many circuits cannot be applied, and if the number of circuit connections is increased, not only does the volume increase, but additional joint connectors must also be connected, so there is a problem of interference with other parts depending on the fixing position.

[0009] Therefore, there is a need to improve this.

[0010] A related background technology is Korean Registered Patent Publication No. 10-2077014 (Registered on Feb. 7, 2020, Title: Bidirectional Joint Connector). The problem to be solved

[0012] The present invention was created in response to the aforementioned necessity, and aims to provide a bidirectional joint connector that improves wiring workability by fixing the position of a recept terminal of a first wiring inserted into one side of a housing and a tap terminal of a second wiring inserted into the other side of a housing in a mutually connected state by a position fixing guide. means of solving the problem

[0014] To achieve the above objective, the bidirectional joint connector according to the present invention is characterized by comprising: a housing having a plurality of connection holes formed through both sides; a first wiring inserted into the connection hole formed on one side of the housing and having a recept terminal at its end; a second wiring inserted into the connection hole formed on the other side of the housing and having a tap terminal at its end that is electrically connected to the recept terminal; and a position fixing guide that guides the tap terminal to be fixed in position while being fitted to the recept terminal within the housing.

[0015] The above position fixing guide is characterized by including a fitting confirmation space formed openly on the periphery of the housing to allow checking the fitting state of the tab terminal and the recept terminal, a coupling cover coupled to the housing to cover the fitting confirmation space, and a fitting retention locking part that locks the coupling cover to the housing so that the fitting state of the tab terminal and the recept terminal is maintained when the coupling cover covers the fitting confirmation space.

[0016] The above-described fitting retention locking part is characterized by including an elastic locking connection part that connects the coupling cover and the housing so that the coupling cover is elastically hooked onto the housing, and a movement restriction guide part that guides the coupling cover to restrict the movement of the tab terminal and the recept terminal.

[0017] The above elastic locking connection part is characterized by including a locking groove formed by being recessed on the periphery of the housing and a locking hook formed protruding from the inner surface of the coupling cover so as to be elastically locked and received in the locking groove.

[0018] The above movement restriction guide is characterized by including a first locking hole formed through the tab terminal, a second locking hole formed through the recept terminal so as to communicate with the first locking hole, and a fitting shaft formed protruding from the inner side of the coupling cover so as to be fitted into the first locking hole and the second locking hole. Effects of the invention

[0020] According to the bidirectional joint connector of the present invention, the recept terminal of a first wiring inserted into one side of the housing and the tap terminal of a second wiring inserted into the other side of the housing are fixed in a position connected to each other by a position fixing guide, thereby enabling the implementation of more circuits than before and improving wiring workability.

[0023] Hereinafter, an embodiment of a joint connector according to the present invention will be described with reference to the attached drawings. In this process, the thickness of lines or the size of components shown in the drawings may be exaggerated for clarity and convenience of explanation.

[0024] Furthermore, the terms described below are defined in consideration of their functions within the present invention, and these may vary depending on the intent or practice of the user or operator. Therefore, the definitions of these terms should be based on the content throughout this specification.

[0026] FIG. 1 is a perspective view illustrating a bidirectional joint connector according to an embodiment of the present invention, FIG. 2 is an exploded perspective view illustrating a bidirectional joint connector according to an embodiment of the present invention, FIG. 3 is a front cross-sectional view illustrating a bidirectional joint connector according to an embodiment of the present invention, and FIG. 4 is a side cross-sectional view illustrating a bidirectional joint connector according to an embodiment of the present invention.

[0028] As illustrated in FIGS. 1 to 4, a joint connector according to one embodiment of the present invention includes a housing (10), a first wiring (20), a second wiring (30), and a position fixing guide (40).

[0029] A plurality of connection holes (11) are formed through each side of the housing (10).

[0030] This housing (10) serves to provide a space in which the first wiring (20) and the second wiring (30) are interconnected, and is formed in the shape of an insulated rectangular block.

[0031] At this time, the connection hole portion (11) is formed in a rectangular shape in the housing (10) so as to be partitioned along the width direction of the housing (10). Of course, although the connection hole portion (11) is shown as having three on each side of the housing (10) in the drawing, it is not limited to this and can be made in various numbers.

[0032] And, the first wiring (20) is inserted into a connection hole (11) formed on one side of the housing (10) and is provided with a recept terminal (21) at its end, and the second wiring (30) is inserted into a connection hole (11) formed on the other side of the housing (10) and is provided with a tap terminal (31) at its end that is directly fitted into the recept terminal (21). That is, when the tap terminal (31) is directly fitted into the recept terminal (21), the first wiring (20) and the second wiring (30) are connected so as to be electrically conductive to each other.

[0033] Meanwhile, the position fixing guide (40) guides the tap terminal (31) to be fixed in position while being fitted into the recept terminal (21) within the housing (10).

[0034] Specifically, the position fixing guide (40) includes a fitting confirmation space (41) formed open on the periphery of the housing (10) to allow checking the fitting state of the tap terminal (31) and the recept terminal (21), a coupling cover (42) coupled to the housing (10) to cover the fitting confirmation space (41), and a fitting maintenance locking part (43) that locks the coupling cover (42) to the housing (10) so that the fitting state of the tap terminal (31) and the recept terminal (21) is maintained when the coupling cover (42) covers the fitting confirmation space (41).

[0035] Here, the fitting confirmation space (41) is open to communicate with the connection hole (11) in the housing (10), and a plurality of partition guide members (42a) are formed protruding from the coupling cover (42) to be received in the fitting confirmation space (41) and to individually partition the tap terminal (31) and the recept terminal (21).

[0036] Of course, the connecting cover (42) is formed in a U-shape to cover the perimeter of the housing (10) and is made of an insulating material.

[0037] In addition, the fitting retention locking part (43) includes an elastic locking connection part (44) that connects the coupling cover (42) and the housing (10) so that the coupling cover (42) is elastically hooked to the housing (10), and a movement restriction guide part (45) that guides the coupling cover (42) to restrict the movement of the tap terminal (31) and the recept terminal (21).

[0038] At this time, the elastic locking connection part (44) includes a locking groove (44a) formed by being recessed on the periphery of the housing (10) and a locking hook (44b) formed protruding from the inner surface of the coupling cover (42) so as to be elastically locked and received in the locking groove (44a).

[0039] That is, in the process of the housing (10) being accommodated so that the coupling cover (42) covers the fitting confirmation space (41), the coupling cover (42) is elastically deformed by the catch hook (44b) when it comes into contact with the periphery of the housing (10), and then is restored at the moment the catch groove (44a) and the catch hook (44b) align, so that it is fixed in position while covering the periphery of the housing (10).

[0040] Additionally, the movement restriction guide (45) includes a first locking hole portion (45a) formed through the tap terminal (31), a second locking hole portion (45b) formed through the recept terminal (21) to communicate with the first locking hole portion (45a), and a fitting shaft portion (45c) formed protruding from the inner side of the coupling cover (45) to be fitted into the first locking hole portion (45a) and the second locking hole portion (45b).

[0041] That is, when the coupling cover (42) is fixedly coupled to the housing (10) through the elastic locking connection part (44), the fitting shaft part (45c) is inserted into the first locking hole part (45a) and the second locking hole part (45b), thereby preventing the tap terminal (31) and the recept terminal (21) from moving in the opposite direction to the direction in which they are inserted into the connection hole part (11) of the housing (10).

[0042] Thus, since the first wiring (20) and the second wiring (30) can be fixedly connected on both sides of the housing (10), there is no need to prepare additional joint connectors for branch line connection, and since the housing (10) can be supported by the first wiring (20) and the second wiring (30), there is no need to fix the housing (10) to the vehicle body, thereby improving work convenience.

[0044] Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom.

[0045] Therefore, the true technical scope of protection of the present invention should be determined by the following claims. Explanation of the symbols
