[0003] Technology field

[0004] The present invention relates to a connector, and more particularly, to a connector capable of conducting electricity to an electric device.

[0005] A connector electrically connected to a component is an electrical component that can conduct current between said component and said other component by being coupled with another connector that is electrically connected to another component. Generally, a connector is composed of a connector body that forms an overall appearance and a conductive terminal that is penetrated and coupled to the connector body. The connector body is formed to fit the shape of the body of another connector to achieve coupling between the connectors, and the terminal is coupled with the terminal of another connector to achieve electrical connection between the components.

[0006] However, conventional connectors have had problems with ensuring sufficient insulation from other electrical components because the terminals are exposed outside the connector body. Specifically, connectors typically feature a pair of terminals, each representing a positive and negative pole. Conventional connectors have struggled to ensure sufficient insulation distance or high reliability between these terminals. Furthermore, the bonding and assembly between the terminals and the connector body in conventional connectors have been weak, leading to unexpected defects, such as the two components becoming detached from each other. Consequently, there has been an urgent need for the development of a connector that can sufficiently secure terminal insulation while also offering high bonding and assembly capabilities.

[0007] The present invention has been devised to solve the above problems, and the object of the present invention is to provide a connector with improved insulation for a terminal.

[0008] Another object of the present invention is to provide a connector having improved coupling and assembling properties between a connector body forming the exterior of the connector and a terminal.

[0009] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art to which the present invention pertains from the description below.

[0010] According to one aspect of the present invention, a connector is provided, comprising: a connector body including a main body portion providing a receiving space and a sub body portion connected to the receiving space and providing a connecting space with one side open; a cable having an end disposed in the receiving space; a terminal including a cable coupling portion coupled to the end of the cable and a terminal portion extending from the cable coupling portion to the connecting space; and a retainer coupling the terminal and the connector body, wherein the retainer includes a retainer body portion disposed in the receiving space and fixing the cable coupling portion in position; and a retainer including a terminal receiving portion extending from the retainer body portion and receiving the terminal portion therein.

[0011] At this time, the terminal receiving portion may have a hollow shape.

[0012] At this time, the terminal portion has a cylindrical shape, and the terminal receiving portion can be arranged coaxially with the terminal portion.

[0013] At this time, the terminal receiving portion may have a longer length than the terminal portion so as to cover the outer circumference of the terminal portion.

[0014] At this time, the retainer may further include a terminal catch portion protruding from the terminal receiving portion to prevent the terminal portion from moving outside the terminal receiving portion.

[0015] At this time, the terminal catch portion may protrude from the inner surface of the terminal receiving portion at the end of the terminal receiving portion.

[0016] At this time, the terminal engaging portion may be formed in a ring shape having an inner diameter smaller than the outer diameter of the end of the terminal portion.

[0017]

[0018] *At this time, the sub-body part can be extended parallel to the terminal part.

[0019] At this time, the sub-body portion may have a longer length than the terminal portion and the terminal receiving portion.

[0020] At this time, the retainer body part may have a body shape that accommodates the cable coupling part and has one side open so that the end of the cable can enter inside.

[0021] At this time, the retainer body part and the terminal receiving part may have different widths so that the connecting part connecting the retainer body part and the terminal receiving part can be stepped, and the connector body may further include a retainer hooking part provided between the receiving space and the connecting space so that the connecting part can be hooked.

[0022] At this time, the retainer may further include a body-side hook portion provided on the outer surface of the retainer body portion and capable of being hooked to the inner wall of the receiving space.

[0023] At this time, the body-side catch portions may be configured as a pair and may face each other with the retainer body portion interposed therebetween.

[0024] At this time, one side may further include a coupling member coupled to the retainer body portion and the other side may further include a coupling member coupled to the cable coupling portion.

[0025] At this time, the coupling member may include a coupling body part that is fitted into the retainer body part; and a ring part that extends from the coupling body part and wraps the cable coupling part in the circumferential direction of the cable.

[0026] At this time, the connector body may further include a partition wall portion that divides the receiving space into first and second receiving spaces that extend parallel to each other.

[0027] At this time, the terminal includes first and second terminals, the cable coupling portion of the first terminal is arranged in the first receiving space, the cable coupling portion of the second terminal is arranged in the second receiving space, and the terminal portions of the first and second terminals can be arranged together in the connection space.

[0028] At this time, the retainer includes first and second retainers, and the terminal receiving portion of the first retainer can receive the terminal portion of the first terminal, and the terminal receiving portion of the second retainer can receive the terminal portion of the second terminal.

[0029] According to one aspect of the present invention, since the terminal receiving portion of the retainer receives the terminal of the terminal inside, the insulation of the connector can be improved.

[0030] According to another aspect of the present invention, since the retainer body of the retainer can fix the position of the terminal receiving portion of the terminal coupled with the cable, the assembling and mating properties of the connector can be improved.

[0044] Figures 1 and 2 disclose a connector (1) according to one embodiment of the present invention. The connector (1) according to one embodiment of the present invention may be a connector for conducting current through a cable (20) with another electrical device.

[0045] Referring to FIGS. 1 to 5, a connector (1) according to one embodiment of the present invention may include a connector body (10). The connector body (10) may house and protect other components of the connector (1) within it, or may provide a base on which other components are installed. For this purpose, the connector body (10) may be made of a plastic having a predetermined rigidity, but the material of the connector body (10) is not limited thereto.

[0046] In this embodiment, the connector body (10) may include a main body portion (12). The main body portion (12) may be configured to provide a receiving space (A). The receiving space (A) may be a space for receiving an end of a cable (20) and a cable coupling portion (32) of a terminal (30) coupled with the end of the cable (20).

[0047] In this embodiment, the main body part (12) may be provided as a cylindrical member extending in the vertical direction (Z-axis direction). Accordingly, an accommodation space (A) may be formed inside the main body part (12). The accommodation space (A) may have a predetermined length in the extension direction of the main body part (12).

[0048] At this time, in the present embodiment, the receiving space (A) can be opened downward (in the negative direction of the Z-axis). To this end, a main body-side opening (12a) can be provided on the lower side (in the negative direction of the Z-axis) of the main body part (12). The main body-side opening (12a) can be an opening connected to the lower part of the receiving space (A).

[0049] Accordingly, a cable (20) can enter the interior of the main body (12), and the end of the cable (20) can be placed in the receiving space (A). In addition, the main body (12) can protect the end of the cable (20) and the cable joint (32) connected thereto from external impact or contamination.

[0050] Meanwhile, in the present embodiment, the upper portion of the receiving space (A) can be connected to the connection space (B) described later. For this purpose, the upper portion of the receiving space (A) can be opened upward (in the positive direction of the Z-axis).

[0051] At this time, referring to FIGS. 2 and 5, the connector body (10) of the connector (1) according to one embodiment of the present invention may include a partition wall portion (14). The partition wall portion (14) may be positioned in the receiving space (A). The partition wall portion (14) may partition the receiving space (A) into a first receiving space (A1) and a second receiving space (A2).

[0052] This configuration may be intended to allow a pair of cables (20) to be placed in the first and second receiving spaces (A1, A2), respectively. The pair of cables (20) may each constitute a cathode and an anode. A bulkhead (14) may be placed between the pair of cables (20) to insulate them from each other.

[0053] In this embodiment, the bulkhead portion (14) can extend in the vertical direction (Z-axis direction) parallel to the main body portion (12). Accordingly, the first and second receiving spaces (A1, A2) can extend in the vertical direction (Z-axis direction) parallel to each other.

[0054] The first and second receiving spaces (A1, A2) can be opened downward (in the negative direction of the Z-axis), respectively. The main body-side opening (12a) can be partitioned by the lower end of the bulkhead (14), thereby forming a pair of sub-openings. The upper portions of the first and second receiving spaces (A1, A2) can be connected to the connection space (B), respectively.

[0055] Due to this, the first and second receiving spaces (A1, A2) partitioned by the bulkhead (14) are not directly connected to each other, but can be indirectly connected through the connection space (B) or the outside.

[0056] At this time, referring to FIGS. 4 and 7, a retainer engaging groove (12b) may be formed in the main body portion (12). The retainer engaging groove (12b) may be a groove in which a body-side engaging portion (44) of the retainer (40) described later is engaged. Accordingly, the coupling and assembling properties between the retainer (40) and the connector body (10) may be improved.

[0057] In this embodiment, the retainer engaging groove (12b) may be formed on the inner wall of the receiving space (A). At this time, the retainer engaging groove (12b) may be configured in multiple numbers and may be formed on the inner walls of the first and second receiving spaces (A1, A2), respectively.

[0058] Hereinafter, the retainer engaging groove (12b) formed in the first receiving space (A1) will be described as a reference. The configuration of the retainer engaging groove (12b) described below may be configured in the same manner in the second receiving space (A2).

[0059] In this embodiment, a retainer engaging groove (12b) may be formed concavely on the inner wall of the first receiving space (A1). At this time, the retainer engaging grooves (12b) may be configured as a pair. The pair of retainer engaging grooves (12b) may be arranged opposite each other with a retainer (40) interposed therebetween. Accordingly, both sides of the retainer (40) may be stably fixed to the connector body (10).

[0060] To be more specific, as illustrated, a pair of retainer engaging grooves (12b) can be formed at the front (positive direction of the X-axis) and rear (negative direction of the X-axis), respectively. As needed, the position of the retainer engaging grooves (12b) can be appropriately modified.

[0061] Referring again to FIGS. 1 to 5, the connector body (10) of the connector (1) according to one embodiment of the present invention may include a sub-body portion (16). The sub-body portion (16) may be configured to provide a connection space (B). The connection space (B) may be a space into which another connector is fitted and coupled. Accordingly, the terminal (30) of the connector (1) and the terminal of another connector may be electrically connected in the connection space (B).

[0062] In this embodiment, the sub-body part (16) may extend upward (in the positive direction of the Z-axis) from the main body part (12). The sub-body part (16) may be provided in a cylindrical or hollow shape extending in the vertical direction (in the Z-axis direction). Accordingly, a connection space (B) may be formed inside the sub-body part (16).

[0063] In this embodiment, the connection space (B) may be opened upward (in the positive direction of the Z-axis). This may be to allow another connector to enter the connection space (B). For this purpose, a sub-body-side opening (16a) may be provided at the upper end of the sub-body portion (16).

[0064] In this embodiment, the sub-body side opening (16a) may be an opening connected to the upper portion of the connection space (B). The sub-body side opening (16a) may have a sufficiently large width to allow another connector to enter.

[0065] At this time, referring to FIG. 4, in this embodiment, the length (L_16) of the sub-body portion (16) may be longer than the length (L_34) of the terminal portion (34) of the terminal (30) described later and the length (L_46) of the terminal receiving portion (46) of the retainer (40). At this time, the length may be a length measured based on the up-down direction (Z-axis direction).

[0066] This configuration may be intended to ensure that the terminal portion (34) of the terminal (30) and the terminal receiving portion (46) of the retainer (40) do not protrude outside the connection space (B) but are positioned inside the connection space (B). Accordingly, the configurations can be protected from external impact or contamination.

[0067] Of course, if necessary, the terminal portion (34) of the terminal (30) and / or the terminal receiving portion (46) of the retainer (40) may be provided with a length longer than the sub-body portion (16). In this case, the end of the terminal portion (34) of the terminal (30) and / or the terminal receiving portion (46) of the retainer (40) will be exposed to the outside of the connector body (10).

[0068] Meanwhile, referring to FIGS. 4 and 5, the connector body (10) of the connector (1) according to one embodiment of the present invention may include a retainer catch portion (18). The retainer catch portion (18) may be configured to prevent the retainer (40) described below from slipping out toward the upper side (positive direction of the Z-axis) of the connector body (10).

[0069] In this embodiment, a retainer catch (18) may be provided between the connection space (B) and the receiving space (A). The retainer catch (18) may be provided as a partition wall dividing the connection space (B) and the receiving space (A). The retainer catch (18) may extend in a horizontal direction (Y-axis direction or X-axis direction).

[0070] At this time, a predetermined hole (18a, 18b) may be formed in the retainer catch (18). The hole (18a, 18b) may be a hole for connecting the connection space (B) and the receiving space (A). The hole (18a, 18b) may include a first hole (18a) connecting the connection space (B) and the first receiving space (A1) and a second hole (18b) connecting the connection space (B) and the second receiving space (A2).

[0071] At this time, the holes (18a, 18b) may have a diameter larger than the terminal receiving portion (46) of the retainer (40) described later, and may have a diameter smaller than the retainer body portion (42). Accordingly, the retainer body portion (42) is caught by the retainer catch portion (18), so that the retainer (40) can be restricted from falling out upward (in the positive direction of the Z-axis).

[0072] Meanwhile, in the present embodiment, the main body part (12) and the sub-body part (16) of the connector body (10) have been described as being cylindrical or hollow, providing a receiving space (A) and a connecting space (B). However, the shapes of the main body part (12) and the sub-body part (16) are not particularly limited, as long as they can provide a receiving space (A) and a connecting space (B).

[0073] For example, the main body part (12) and / or the sub-body part (16) may have a side in the extension direction open, so that the side of the receiving space (A) and / or the connecting space (B) may be exposed or opened to the outside. Alternatively, the main body part (12) and / or the sub-body part (16) may be provided with a portion that is curved. Accordingly, the receiving space (A) or the connecting space (B) may also have a curved shape.

[0074] Referring to FIGS. 1 to 5, a connector (1) according to one embodiment of the present invention may include a cable (20). The cable (20) may be a cable that electrically connects the connector (1) to an external electrical device.

[0075] At this time, the cables (20) may be provided as a pair. The pair of cables (20) may be arranged parallel to each other. With reference to FIG. 3, the cable (20) located relatively to the left (in the negative direction of the Y-axis) is referred to as the first cable (20-1), and the cable (20) located relatively to the right (in the positive direction of the Y-axis) is referred to as the second cable (20-1). The first and second cables (20-1, 20-1) may form positive and negative poles, respectively.

[0076] In this embodiment, the first and second cables (20-1, 20-2) may extend to the first and second receiving spaces (A1, A2), respectively. In addition, the ends of the first and second cables (20-1, 20-2) may be placed in the first and second receiving spaces (A1, A2), respectively.

[0077] Referring to FIGS. 1 to 3, a connector (1) according to one embodiment of the present invention may include a terminal (30) coupled with a cable (20). The terminal (30) may be configured to electrically connect the cable (20) to another terminal (30). Accordingly, an electrical device connected to the cable (20) of the connector (1) may be electrically connected to another electrical device connected to another terminal (30).

[0078] In this embodiment, the terminals (30) may be configured as a pair to correspond to a pair of cables (20). Hereinafter, the terminal (30) coupled with the first cable (20-1) is referred to as the first terminal (30-1), and the terminal (30) coupled with the second cable (20-2) is referred to as the second terminal (30-2).

[0079] Below, the first terminal (30-1) among a pair of terminals (30) will be described. The configuration of the first terminal (30-1) described below may also be configured in the same manner for the second terminal (30-2).

[0080] In this embodiment, the first terminal (30-1) may include a cable coupling portion (32). The cable coupling portion (32) may be placed in the first receiving space (A1). The cable coupling portion (32) may be coupled to the end of the first cable (20). Meanwhile, the cable coupling portions (32) of the second terminal (30-2) may be placed in the second receiving space (A2), respectively. Accordingly, they may be insulated by the bulkhead portion (14).

[0081] In this embodiment, the cable joint (32) may have a cylindrical shape extending in the vertical direction (Z-axis direction) so that the end of the first cable (20) can be inserted inside. However, the structure or shape of the cable joint (32) is not particularly limited as long as it can be joined with the end of the first cable (20).

[0082] In this embodiment, the first terminal (30-1) may include a terminal portion (34). The terminal portion (34) may be a portion connected to another terminal outside the connector (1). To this end, the terminal portion (34) may be configured to be coupled with a portion of another terminal. For example, the terminal portion (34) may be configured to be coupled with a portion of another terminal in a shape-matched manner. The terminal portion (34) may be configured using various known techniques for implementing connections between terminals.

[0083] In this embodiment, the terminal portion (34) can extend upward (in the positive direction of the Z-axis) from the cable coupling portion (32). The terminal portion (34) can pass through the hole (18a) of the retainer catch portion (18). The end of the terminal portion (34) can be placed in the connection space (B). Accordingly, the terminal portion (34) can be coupled with a terminal of another connector in the connection space (B).

[0084] Meanwhile, the terminal portion (34) of the first terminal (30-1) and the terminal portion (34) of the second terminal (30-2) may be arranged together in the connection space (B). The terminal portion (34) of the first terminal (30-1) and the terminal portion (34) of the second terminal (30-2) may be arranged parallel to each other in the connection space (B). The terminal portion (34) of the first terminal (30-1) and the terminal portion (34) of the second terminal (30-2) may be arranged at a predetermined distance in the horizontal direction (Y-axis direction).

[0085] However, since the connection space (B) is not provided with a separate configuration for dividing it, insulation may not be secured between the terminal portion (34) of the first terminal (30-1) and the terminal portion (34) of the second terminal (30-2). To this end, a terminal receiving portion (46) of a retainer (40) described later may be provided on the outside of the terminal portion (34). This will be described later together with the retainer (40).

[0086] Referring to FIGS. 1 to 5, a connector (1) according to one embodiment of the present invention may include a retainer (40). The retainer (40) may be configured to secure the end of the cable (20) and the terminal (30) to the connector body (10) while insulating them from the outside. For this purpose, the retainer (40) may be made of a material having insulating properties.

[0087] In this embodiment, the retainer (40) may be configured as a pair corresponding to a pair of cables (20) and a pair of terminals (30). Hereinafter, the retainer (40) that secures the first terminal (30-1) to the connector body (10) is referred to as a first retainer (40-1), and the retainer (40) that secures the second terminal (30-2) to the connector body (10) is referred to as a second retainer (40-2).

[0088] Below, the configuration of the first retainer (40-1) will be described. Each configuration of the first retainer (40-1) described below may be configured in the same manner for the second retainer (40-2).

[0089] A first retainer (40-1) of a connector (1) according to one embodiment of the present invention may include a retainer body portion (42). The retainer body portion (42) may be arranged in a first receiving space (A1) and configured to fix a cable coupling portion (32) of a first terminal (30-1) in position in the first receiving space (A1).

[0090] In the present embodiment, the retainer body (42) may have a body shape having a retainer space (C) provided therein. More specifically, the retainer body (42) may be provided as a structure having a generally box shape. Accordingly, the cable connection portion (32) may be accommodated within the retainer body (42) and protected from external impact or contamination, while also enhancing insulation from the outside.

[0091] At this time, the retainer space (C) may be opened downward (in the negative direction of the Z-axis). This may be to allow the end of the first cable (20-1) to enter the inside of the retainer body (42). To this end, a retainer body-side opening (42a) connected to the retainer space (C) may be provided at the lower portion of the retainer body (42). The retainer body-side opening (42a) may be formed as an opening that is opened downward (in the negative direction of the Z-axis).

[0092] Meanwhile, referring to FIGS. 4, 5, and 8, in the present embodiment, a joining member joining portion (42b) may be provided on the side of the retainer body portion (42). The joining member joining portion (42b) may be a portion to which a joining member (50) described later is joined.

[0093] In the present embodiment, the coupling member joining portion (42b) may be defined as a space that is open to the outside and has a square cross-section corresponding to the shape of the coupling member (50). The retainer space (C) may be communicated with the outside of the retainer body portion (42) by the coupling member joining portion (42b). Of course, the structure or shape of the coupling member joining portion (42b) is not particularly limited as long as coupling with the coupling member (50) can be achieved.

[0094] In this embodiment, the retainer body (42) may be provided with a coupling projection engaging portion (42c). The coupling projection engaging portion (42c) may be configured to engage with a coupling projection (56) of a coupling member (50) described later. For this purpose, the coupling projection engaging portion (42c) may be provided as a recessed groove in the inner wall of the retainer space (C).

[0095] In addition, one side of the coupling protrusion coupling portion (42c) can be connected to the coupling member coupling portion (42b). Accordingly, the coupling protrusion (56) of the coupling member (50) coupled to the coupling member coupling portion (42b) can be inserted into the coupling protrusion coupling portion (42c).

[0096] At this time, in the present embodiment, the coupling projection connecting portion (42c) may be configured as a pair. The pair of coupling projection connecting portions (42c) may be arranged symmetrically around the cable connecting portion (32) arranged in the retainer space (C). The effect of this configuration will be described later together with the coupling member (50).

[0097] Meanwhile, in the present embodiment, the retainer body (42) has been described as a box-shaped structure with one side open. However, the structure or shape of the retainer body (42) is not particularly limited as long as it can secure the cable coupling portion (32) to the receiving space (A). For example, the retainer body (42) may have a portion that is curved, or may be configured such that a portion is open so that the cable coupling portion (32) is exposed to the outside of the retainer body (42).

[0098] Referring to FIGS. 4 and 7, the retainer (40) of the connector (1) according to one embodiment of the present invention may include a body-side engaging portion (44). The body-side engaging portion (44) may be configured to be engaged with the retainer engaging groove (12b) of the aforementioned connector body (10) to improve coupling and assembling properties between the connector body (10) and the retainer (40).

[0099] The body-side catch portion (44) may extend outward from the outer surface of the retainer body portion (42). At this time, the body-side catch portions (44) may be configured as a pair. The pair of body-side catch portions (44) may be arranged oppositely with the retainer body portion (42) as the center. Accordingly, the retainer body portion (42) may be more stably positioned and fixed in the first receiving space (A1).

[0100] Referring to FIGS. 1 to 6, a first retainer (40-1) of a connector (1) according to one embodiment of the present invention may include a terminal receiving portion (46). The terminal receiving portion (46) may be configured to receive a terminal portion (34) of a first terminal (30-1).

[0101] Accordingly, the terminal portion (34) can be protected from external impact or contamination, and its insulation with other components can be improved. For example, the insulation between the terminal portion (34) of the first terminal (30-1) and the terminal portion (34) of the second terminal (30-2), which are arranged together in the connection space (B), can be significantly improved.

[0102] In this embodiment, the terminal receiving portion (46) can extend upward (in the positive direction of the Z-axis) from the retainer body portion (42). The terminal receiving portion (46) can pass through the hole (18a) of the retainer catch portion (18). The terminal receiving portion (46) can be placed in the connection space (B).

[0103] At this time, the terminal receiving portion (46) may be provided in a hollow shape so that the terminal portion (34) is received on the inside. The terminal receiving portion (46) may be arranged coaxially with the terminal portion (34). Accordingly, the structure of the retainer (40) can be configured more compactly.

[0104] In the present embodiment, the length (L-46) of the terminal receiving portion (46) may be longer than the length (L-34) of the terminal portion (34). In this case, the length may be a length measured in the vertical direction (Z-axis direction). Accordingly, the outer circumference of the terminal portion (34) may be entirely covered by the terminal receiving portion (46). This may further improve the insulation performance of the terminal (30) achieved by the terminal receiving portion (46).

[0105] Meanwhile, in this embodiment, the terminal receiving portion (46) has been described as a cylindrical member. However, the structure or shape of the terminal receiving portion (46) is not particularly limited as long as it can receive at least a portion of the terminal portion (34) therein.

[0106] Meanwhile, referring to FIGS. 4 to 6, the first retainer (40-1) of the connector (1) according to one embodiment of the present invention may include a terminal catch portion (48). The terminal catch portion (48) may be configured to prevent the terminal portion (34) from falling out of the terminal receiving portion (46).

[0107] In this embodiment, a terminal catch (48) may be provided at an end of the terminal receiving portion (46). The terminal catch (48) may be positioned higher (in the positive direction of the Z-axis) than the end of the terminal portion (34). This may be to limit the terminal portion (34) from moving upward (in the positive direction of the Z-axis).

[0108] At this time, the terminal catch portion (48) may protrude from the inner surface of the terminal receiving portion (46). As illustrated, the terminal catch portion (48) may have a ring shape that is open in the vertical direction (Z-axis direction). The inner diameter (d_48) of the terminal catch portion (48) may be smaller than the outer diameter (d_34) of the end of the terminal portion (34).

[0109] Accordingly, the terminal portion (34) can be prevented from falling off by interfering with the terminal catch portion (48) in the vertical direction (Z-axis direction). Of course, if necessary, the terminal catch portion (48) can be partially formed in the circumferential direction of the terminal receiving portion (46) on the inner surface of the terminal receiving portion (46).

[0110] Meanwhile, in this embodiment, the terminal catch (48) has been described as being provided at the end of the terminal receiving portion (46). However, the terminal catch (48) may be positioned lower than the end of the terminal portion (34) and configured to catch on the outer circumference of the terminal portion (34).

[0111] Referring to FIGS. 3 to 5 and 8, a connector (1) according to one embodiment of the present invention may include a joining member (50). The joining member (50) may be configured to improve the joining force and assembling ability between the retainer (40) and the terminal (30).

[0112] In this embodiment, the coupling member (50) may include a coupling body portion (52). The coupling body portion (52) may be a body coupled to the coupling member coupling portion (42b) of the retainer body portion (42).

[0113] As illustrated, the coupling body portion (52) may be provided as a member having a square plate shape. Accordingly, the coupling body portion (52) may be fitted into a space defined by the coupling member coupling portion (42b).

[0114] In this embodiment, the coupling member (50) may include a ring portion (54). The ring portion (54) may extend from the coupling body portion (52) to the retainer space (C). At this time, the ring portion (54) may have a shape that wraps around the outer periphery of the cable coupling portion (32) in the circumferential direction of the cable (20).

[0115] Accordingly, the ring portion (54) can be combined with the cable coupling portion (32) in a shape-fitting manner. At this time, the ring portion (54) can extend in the vertical direction (Z-axis direction). The ring portion (54) can wrap the cable coupling portion (32) in the vertical direction (Z-axis direction) by a predetermined section. As a result, the coupling force between the coupling member (50) and the terminal (30) and the coupling property between the retainer (40) and the terminal (30) can be improved.

[0116] In this embodiment, the joining member (50) may include a joining projection (56). The joining projection (56) may be configured to improve the joining force between the retainer (40) and the joining member (50).

[0117] The coupling protrusion (56) can protrude outward from the ring portion (54). Accordingly, the coupling protrusion (56) can be inserted into the coupling protrusion engaging portion (42c) provided on the inner wall of the retainer space (C). At this time, the coupling protrusion (56) can extend in the circumferential direction of the cable engaging portion (32).

[0118] Meanwhile, in the present embodiment, the coupling protrusions (56) may be configured as a pair. The pair of coupling protrusions (56) may be arranged oppositely with respect to the ring portion (54). Accordingly, the coupling member (50) may be more stably coupled to the retainer body portion (42).

[0119] In this way, in this embodiment, the ring portion (54) of the coupling member (50) is coupled with the cable coupling portion (32) of the terminal (30), and the coupling body portion (52) is coupled with the retainer body portion (42), so that the assembly and coupling properties between the retainer (40) and the terminal (30) can be improved.

[0120] Although the present invention has been described above with reference to limited embodiments and drawings, the present invention is not limited thereto, and various embodiments are possible within the scope equivalent to the technical idea of ​​the present invention and the patent claims to be described below by a person having ordinary skill in the art to which the present invention pertains.
