That is, the receptacle connector (100) according to the present utility model may be formed so as to include the power supply terminals (110, 190) and the signal terminals (180) when the insulating housing (10) including the first wall (11), the second wall (12), the third wall (13), the fourth wall (14) and the bottom wall (18) is insert molded.

Since the power supply terminals (110, 190) coupled to both sides of the insulating case (10) are formed in the same form, only one side of the power supply terminal (110) will be described.

The insulating housing (10) comprises a first wall (11), a second wall (12), a third wall (13), a fourth wall (14), a central island (15) and a bottom wall (18).

Here, the deep drawing (DEEP DRAWING) process is a process of manufacturing a product of a container pattern without a seam using a plate material, and specifically means that the plate material is compressed in a circumferential direction and pressurized in a depth direction to manufacture the product.

The first cover (111), the second cover (113), and the third cover (115) of the power terminal (110) are formed by a deep drawing process, and the inner cover surface and the outer cover surface of each of the first cover (111), the second cover (113), and the third cover (115) are connected and continuously formed.

That is, the first cover portion (111) is formed in a cladding manner on the upper side of the first wall (11) of the insulating case (10), and may include a first inner cover surface (111 a) formed on the inner side surface of the first wall (11) and a first outer cover surface (111 c) formed on the outer side surface of the first wall (11).

Therefore, the power terminal (110) is formed by the first cover part (111), the second cover part (113) and the third cover part (115) to cover the insulating shell (10), so that the combination position can be guided and the insulating shell (10) can be protected when the power terminal is combined with the plug connector (200).

In addition, locking grooves (111 b, 115 b) may be formed in the first inner cover surface (111 a) and the third inner cover surface (115 a) so as to be combined and fixed with terminals of the plug connector (200) when combined with the plug connector (200).

The second outer cover surface (113 c) may be formed by connecting connection portions (116, 117) to one side and the other side, respectively, and the connection portions (116, 117) bent and connected to the second outer cover surface (113 c) may be connected to arm portions (121, 122) extending in the connector longitudinal direction.

That is, a connecting portion 116 is provided on one side of the second outer cover surface 113c, the connecting portion 116 is connected to an arm portion 121 extending in the connector longitudinal direction, the arm portion 121 is connected to an extension arm portion 123 extending in the connector width direction, and a contact portion 125 may be formed on one side of the extension arm portion 123.

In addition, a connecting portion 117 is provided on the other side of the second outer cover surface 113c, the connecting portion 117 is connected to an arm portion 122 extending in the connector longitudinal direction, the arm portion 122 is connected to an extension arm portion 124 extending in the connector width direction, and a contact portion 126 may be formed on one side of the extension arm portion 124.

The arm portions (121, 122) may include mounting portions (121 a, 122 a) extending downward and mounted on the substrate.

The plate surfaces (121 b, 122 b) of the arm sections (121, 122) may be formed so as to be perpendicular to the bottom surface wall (18).

The plate surfaces of the extension arm sections (123, 124) are parallel to the bottom surface wall, and the upper surfaces of the extension arm sections (123, 124) may be formed so as to be in contact with the bottom surface wall.

Therefore, the first cover part (111), the second cover part (113) and the third cover part (115) are connected by connecting parts (116, 117) arranged at two sides of the second cover part (113), and the arm parts (121, 122) respectively connected with the connecting parts (116, 117) and formed at one side and the other side, and the extension arm parts (123, 124) and the contact parts (125, 126) formed by connecting with the arm parts (121, 122) can be connected.

That is, the first cover part (111), the second cover part (113), the third cover part (115), the connection parts (116, 117), the arm parts (121, 122), the extension arm parts (123, 124), and the contact parts (125, 126) can be connected to form one power supply terminal (110).

This has the following effects: can be firmly combined with the insulating housing (10) during insert molding, and can prevent the insulating housing (10) from contacting with the plug connector (200) when being combined with the plug connector (200), thereby improving durability and reducing damage possibility even if excessive pressure is applied during the combination.

Further, a part of the sections of the arm sections (121, 122) may be located below the cover sections (111, 115).

That is, a part of the section of the first arm section (121) is located below the first cover section (111), and a part thereof can be positioned so as to extend in the longitudinal direction of the connector.

A part of the section of the second arm section (122) is located below the third cover section (115), and a part thereof can be positioned so as to extend in the longitudinal direction of the connector.

For example, in the case where the first arm portion (121) is not present on the lower side of the first cover portion (111) or in the case where the second arm portion (122) is not present on the lower side of the third cover portion (115), only the insulating housing (10) is disposed, so that the possibility of damage becomes high in the case where excessive pressure is applied at the time of coupling with the plug connector (200).

Thereby, the first covering part (111) and the first arm part (121) have an overlapping area in the vertical direction, and the third covering part (115) and the second arm part (122) have an overlapping area in the vertical direction, thereby having the following effects: the overlap region can be used to increase durability by supplementing each other when engaging the plug connector (200), and even if excessive pressure is applied during engagement, the likelihood of damage can be reduced.

The arm sections (121, 122) may be formed so as to extend to the lower sides of the distal ends of the arm sections (121, 122) and connected to the extension arm sections (123, 124).

That is, the contact part (125) may be formed on one side of the first extension arm part (123) while extending to the lower side of the tip of the first arm part (121) and being connected to the first extension arm part (123).

Further, the contact part (126) may be formed on one side of the second extension arm part (124) while extending to the lower side of the tip of the second arm part (122) and being connected to the second extension arm part (124).

The first cover part (111) can be attached to the substrate by an attachment part (121 a) formed by bending and extending a part of the plate surface (121 b) of the first arm part (121), the second cover part (113) can be attached to the substrate by an attachment part (113 d) formed by bending and extending a second outer cover surface (113 c), and the third cover part (115) can be attached to the substrate by an attachment part (122 a) formed by bending and extending a part of the plate surface (122 b) of the second arm part (122).

Thus, the first cover part (111) and the third cover part (115) are formed in a manner of protecting the arm parts (121, 122), and extension arm parts (123, 124) formed by extending from the tail ends of the arm parts (121, 122) and being connected with the bottom surface wall (18) can be firmly combined with the insulating shell (10) during insert molding, so that the durability can be improved.

A bottom surface (118) may be formed and arranged below the inner side surface of the second inner side cover surface (113 a) of the second cover portion (113), and a center island portion cover surface (119) may be provided that extends upward and covers the center island portion (15).

The bottom surface (118) and the central island coverage surface (119) have the following effects: can be firmly combined with the insulating housing (10) during insert molding, and can prevent the insulating housing (10) from contacting with the plug connector (200) when being combined with the plug connector (200), thereby improving durability, and can reduce the possibility of damage even if excessive pressure is applied during the combination.
