The present invention relates to a female connector with rounded edges, and more particularly, to a connector assembly with rounded edges, in which an end of a female connector is formed in a round shape and a guide groove having an inner dimension receiving a wire is formed at an end portion to guide the wire to be curved to correspond to the round shape at a wire harness inlet end and guide the curved wire to be received in the guide groove, thereby guiding reduction of tension of the curved wire and prevention of interference with an external structure.
In general, in the case of most connector assemblies in which a male connector and a female connector are coupled to each other, an end corner portion of the female connector is formed in a rectangular structure and in this case, a wire harness inlet is flat, and as a result, when bending occurs due to a structural characteristic, a wire is suddenly bent and tilted to a lateral side of a connected terminal, which may cause a contact failure of a connector.
In the related art, in order to solve such a problem, a predetermined inclined surface is formed at the wire harness inlet to apply a structure to contact the wire with the inclined surface, but in this case, an edge of the inclined surface is not still gentle, but has a pointed structure, and as a result, it is difficult to solve the problem in that the wire is suddenly bent.
Therefore, in order to solve the problem and a limitation which occur at the wire harness inlet end of the connector in the related art, the present inventor has developed a connector assembly with rounded edges, in which an end of a female connector fastened to a male connector is formed in a round shape and a wire is guided to be curved to correspond to the round shape at a wire harness inlet end to reduce tension applied to the wire, thereby preventing a contact failure and a disconnection failure.
The present invention relates to a female connector with rounded edges, and more particularly, to a connector assembly with rounded edges, in which an end of a female connector is formed in a round shape and a guide groove having an inner dimension receiving a wire is formed at an end portion to guide the wire to be curved to correspond to the round shape at a wire harness inlet end and guide the curved wire to be received in the guide groove, thereby guiding reduction of tension of the curved wire and prevention of interference with an external structure.
According to an embodiment of the present invention, a connector assembly with rounded edges includes: a first connector; and a second connector having a first side that is coupled to the first connector, and a second side having an end portion that is formed in a round shape, in which the second connector is adapted to receive one or more wires which extend outwards from the end portion of the second connector at a curve that corresponds to the round shape.
In an embodiment, the end portion of the second connector may be symmetrical across a longitudinal direction extending from the first side to the second side.
In an embodiment, the first connector and the second connector may be coupled to each other by forcible fitting.
In an embodiment, the second connector may include a plurality of wire passages extending in the longitudinal direction through the second connector, in which the wire passages are partitioned by partitions, and a guide groove formed at end portions of the partitions, in which the guide groove may be dented so as to receive a lateral surface of the one or more wires extending outwards from the end portion of the second connector at a curve that corresponds to the round shape of the second connector.
In an embodiment, the guide groove may be adapted to have a shape that corresponds to the lateral surface of the one or more wires, and may have an internal space adapted to fully receive the lateral surface of the one or more wire. The one or more wires being positioned in the internal space may avoid interference between an external structure and the lateral surface of the one or more wires.
According to an aspect of the present invention, it is advantageous in that a connector assembly with rounded edges, in which an end of a female connector fastened to a mal connector is formed in a round shape and a wire is guided to be curved to correspond to the round shape at a wire harness inlet end to reduce tension applied to the wire, thereby preventing a contact failure and a disconnection failure.
In particular, according to an aspect of the present invention, it is advantageous in that as a guide groove is formed at an end portion of a female connector so that the curved wire is curved in a longitudinal direction, even though the wire is curved according to the round shape of the female connector by an external structure, the wire is received in the guide groove, and as a result, interference with the external structure does not occur.
Hereinafter, a preferred embodiment is presented in order to assist understanding of the present invention. However, the following embodiment is just provided to more easily understand the present invention and contents of the present invention are not limited by the embodiment.
Referring to
In this case, since an end of the female connector 2 is flat, when a wire 1a of the connector assembly 1 is disposed in a structure in which the wire 1a is bent, the wire 1a is suddenly bent by the end of the female connector 2. In this case, while tension of a bent portion of the wire 1a suddenly increases, damage to the wire is caused and the wire 1a is suddenly tilted to a lateral side of a terminal, which causes contact failure of the connector assembly 1.
Accordingly, in the present invention, a technique capable of minimizing a sudden bending phenomenon of the wire 1a will be described with reference to
Referring to
Here, the first connector 110 may mean a male connector having a general shape and the second connector 120 may mean the female connector. Further, the first and second connectors 110 and 120 may be fastened through forcible fitting and coupling to each other.
In this case, the second connector 120 may be formed in a round shape in which the end (more specifically, an end portion in which the wire harness is formed) is not formed to be flat, but laterally symmetric based on a center portion.
More specifically, the end of the second connector 120 protrudes outwards and a corner portion is formed in a rounded gentle curve shape, and as a result, one or more wires which extend to the outside of the second connector 120 may be curved according to the round shape of the second connector 120.
For example, even in a structure in which the connector assembly 100 with the rounded edges is disposed to be bent to left and right sides, one or more wires are slowly bent according to a round shape having a gentle curve shape, and as a result, the tension applied to the wire is suddenly reduced.
Accordingly, through the structure of the present invention, even in a structure in which the connector assembly is disposed to be bent, the sudden bending phenomenon and tension increase of the wire may be prevented and the resulting contact failure and disconnection failure, the contact failure of the connector assembly, etc., may be prevented.
In this case, a guide groove 120a may be formed at the end portion of the second connector 120, which prevents the wire which is slowly curved in the curve shape from being pressed between the external structures. This will be described in more detail with reference to
Referring to
In this case, the guide groove 120a which is dented inside is formed at end portions of partitions partitioning multiple wire passages from each other so as to receive a lateral surface of the wire which comes outside through multiple wire passages.
The guide groove 120a may be formed at each of all of ends of respective partitions and the size of the guide groove 120a is formed to have an internal space having a size to fully receive the lateral surface of the wire.
Accordingly, even though the wire is curved due to interference with the external structure, the wire is received in the guide groove 120a, and as a result, interference between the external structure and the lateral surface of the wire is avoided, thereby avoiding damage and cutting of the wire. This will be described in more detail with reference to
First, referring to
In this case, since the female connector 2 has no structure for preventing the wire from being pressed, there is a problem in that the interference cannot but occur while the wire is pressed.
On the contrary,
In this case, as the wire is fully received in the guide groove 120a, there is no interference between the wire and the external structure, thereby preventing the damage, cutting, etc., of the wire.
The present invention has been described with reference to the preferred embodiments of the present invention, but those skilled in the art will understand that the present invention can be variously modified and changed without departing from the spirit and the scope of the present invention which are defined in the appended claims.
