Description

[Technical Field]

[0001] This application claims priority to and the benefit of Korean Patent Application No. 10-2018-0006972 filed in the Korean Intellectual Property Office on January 19, 2018.

[0002] The present invention relates to a separable high-voltage connector assembly, and more particularly, to a detachable high-voltage connector assembly which can miniaturize a size by individually separating each first pin of a connector mounted on a board to form multiple small connectors and simplify a process and prevent an error that connectors are incorrectly inserted into each other by forming an inserting connector through fastening and assembling each of individually separated second pins, and a manufacturing method thereof.[Background Art]

[0003] In the case of generally used low-voltage connectors, as a battery capacity increases in the battery related electric fields such as energy storage systems (ESS) and electric vehicles, management devices require increasingly higher voltages.

[0004] However, since the low voltage connector cannot be operated in a high-voltage environment at present, a gap between second pins (male pins) must be ensured at a predetermined distance or more, the size of the low-voltage connector cannot but be increased.

[0005] Meanwhile, in the related art, in order to overcome a limitation in connector size, multiple connectors are used and since it is necessary to consider fool proof, it is difficult to supply and demand various kinds of connectors and even though multiple connectors are used, there is a mistake that the second pin and a first pin of the connector are mistakenly inserted.

[0006] Therefore, in order to solve the limitations and the problems associated with high voltage requirements required in the low-voltage connector in the related art, the present inventor has developed a separable high-voltage connector assembly which can miniaturize a size by individually separating each first pin of a connector mounted on a board to form multiple small connectors and simplify a process and prevent an error that connectors are incorrectly inserted into each other by forming an inserting connector through fastening and assembling each of individually separated second pins, and a manufacturing method thereof.

[0007] EP 1 006 617 A2 concerns a high voltage connector consisting of a male assembly that mates with a female assembly having an insulating housing and pin contacts. The pin contacts are not provided with key codes.

[0008] EP 1 835 571 A2 concerns a break apart power connector. The connector comprises an integrally molded body with a plurality of electrical connecting elements. Score lines are provided which may permit the integrally molded body to be broken in at least two pieces. Here, too, there are not provided any key codes on pin contacts.[Detailed Description of the Invention][Technical Problem]

[0014] FIG. 1 is a diagram schematically illustrating a shape of a female connector 1 in the related art. FIG. 2 is a diagram schematically illustrating a configuration of a separable high-voltage connector assembly 100 according to an embodiment of the present invention. FIG. 3 is a flowchart for describing a process of manufacturing and fastening a separable high-voltage connector assembly 100 according to an embodiment of the present invention. [Best Mode]

[0015] 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.

[0016] FIG. 1 is a diagram schematically illustrating a shape of a female connector 1 in the related art.

[0017] Referring to FIG. 1, it can be seen that the female connector 1 in the related art is a structure in which respective first pins 1a are arranged at a regular interval in one integral housing as illustrated in FIG. 1.

[0018] This is a structure that cannot be downsized due to characteristics of the integral housing and has a problem that an unnecessary extra connector pin is generated.

[0019] In particular, in the female connector 1 in the related art, since each first pin 1a protrudes from an inner surface and a voltage value to be conducted corresponds to low voltage, it is not necessary to secure a wide pin interval.

[0020] However, as a battery capacity in an electric industry related to a battery such as an energy storage system (ESS) and an electric automobile is increased, the connector is gradually required to have high voltage and a high-voltage operation may not be performed through the female connector 1 in the related art and to this end, there is a problem that the pin interval should be ensured while enlarging an overall size of the female connector 1 in the related art.

[0021] Therefore, in the present invention, a separable high-voltage connector assembly 100 will be described, which is capable of securing the pin interval without enlarging the overall size of the low-voltage connector 1.

[0022] FIG. 2 is a diagram schematically illustrating a configuration of a separable high-voltage connector assembly 100 according to an embodiment of the present invention.

[0023] Referring to FIG. 2, the separable high-voltage connector assembly 100 according to an embodiment of the present invention may be configured to generally include multiple first (female) pins 110 and male connectors 120 mounted on a board.

[0024] The multiple first (female) pins 110 may refer to a small connector having a similar function to the female connector 1 in the related art, which is illustrated in FIG. 1, which may refer to a kind of female connector made of one or more pins, respectively.

[0025] Further, as the key code is granted to each of the multiple first pins 110, an insertion location of a second pin 120a of the connector 120 to be described below is determined according to a designated key code.

[0026] The connector 120 includes second (male) pins 120a fastened to the multiple first (female) pins 110, respectively and a connector body 120b and as the respective second (male) pins 120a are fastened and assembled to the connector body 120b, the connector 120 is formed as one integral body. Such a connector 120 may refer to, for example, a male connector. However, the present invention is not limited thereto and the multiple first (female) pins 110 and the connector 120 may be applied by changing roles of the female and the male. The separable high-voltage connector assembly 100 according to an embodiment of the present invention may be manufactured in a shape of a female pin in which the multiple first pins are inserted by the respective second pins or a shape of a male pin to be inserted into the respective second pins. Further, the respective second pins may be manufactured in the shape of the female pin inserted by the multiple first pins or the shape of the male pin to be inserted into the multiple first pins.

[0027] More specifically, the multiple fastening grooves (not illustrated) to which the respective second pins 120a are to be fastened and assembled may be arranged in the connector body 120b at a predetermined interval and as the respective second pins 120a are fastened and assembled to the multiple fastening grooves, a creepage and a clearance for each second pin 120a may be adjusted.

[0028] As each pin 120a is manufactured by one pin, the process of the connector 120 may be simplified and since each second pin 120a may be assembled to the connector body 120b, the multiple first pins 110 may be handled by correspondingly increasing the number of second pins 120a.

[0029] Here, the creepage may refer to a total distance between terminals provided inside each of the multiple first pins 110 and in this case, the total distance may refer to a distance including a diameter and a size of a housing (or outer shape) of each first pin 110.

[0030] Further, the clearance may refer to a linear distance between terminals provided inside each of the multiple first pins 110 and in this case, the linear distance refers to just a shortest distance between the terminals disregarding the housing (or outer shape) of each first pin 110.

[0031] As a result, in the separable high-voltage connector assembly 100 according to an embodiment of the present invention, the connector mounted on the board is separated into multiple miniaturized small connectors and the inserted connector is formed in an assembly type in which multiple second pins may be assembled and fastened to the connector, thereby simplifying the process and preventing even an error that the connectors are inserted into each other incorrectly.

[0032] Next, a manufacturing and fastening process of the separable high-voltage connector assembly 100 will be described with reference to FIG. 3.

[0033] FIG. 3 is a flowchart for describing a process of manufacturing and fastening a separable high-voltage connector assembly 100 according to an embodiment of the present invention.

[0034] First, each of multiple first pins is manufactured by one or more pins, which are mounted on the board (S501).

[0035] Next, the connector is integrally formed through fastening and assembling of respective second pins and multiple fastening grooves to which the respective second pins are to be fastened and assembled are arranged in a body of the connector at a predetermined interval and as the respective second pins are fastened and assembled to the multiple fastening grooves, a creepage and a clearance for the each second pin are adjusted (S502).

[0036] Next, the connector is fastened with multiple first pins through the respective second pins fastened and assembled to the body of the connector (S503).

[0037] 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 scope of the present invention which are defined in the appended claims.
