Description

The present invention relates to a connector, and more specifically, to a connector that can increase the allowable current range by additionally installing a sub-power terminal that has a width relatively wider than each signal terminal, thereby ensuring stability when supplying power.

Generally, electronic devices used in various industrial fields, including automobiles, are equipped with printed circuit boards on which various components can be mounted.

Such a printed circuit board is formed with a number of connection terminals for electrically connecting various components, and the connection terminals of the printed circuit board are provided with connectors for connecting to the mating connectors of the corresponding boards.

A conventional connector includes a housing that is coupled to the surface of the board, and terminals that are coupled to the housing and coupled to connect with connection terminals on the board. The terminals are divided into power terminals for supplying power and signal terminals for transmitting signals.

However, in conventional connectors, the allowable current of the power terminals is fixed, so if an overcurrent is applied, it can cause failure of the electronic device, and so a structure that can handle the application of an overcurrent was required. In addition, in conventional connectors, the power terminals and signal terminals are aligned using a transport carrier during assembly, and then insert molding is performed, and the process of separating the carrier from the power terminals and signal terminals is cumbersome.

A prior document related to the present invention is Korean Patent Registration No. 10-1185545 (September 18, 2012), which discloses a connector for connecting boards.

Republic of Korea Patent No. 10-1185545 (2012.09.18.)

The object of the present invention is to provide a connector and a manufacturing method thereof that can increase the allowable current range by additionally installing sub-power terminals that are relatively wider than each signal terminal, and can ensure stability when supplying power.

The object of the present invention is to provide a connector and a manufacturing method thereof that ensures ease of assembly by extending the mounting parts of the main power terminal, signal terminal, and sub power terminal so that they protrude from the side of the housing and individually connecting them to a transfer carrier, allowing each terminal to be moved individually during assembly and then insert molded.

In addition, the outer contact portions of the signal terminal and the sub-power terminal may be formed with a recessed locking groove to lock and position the mating connector when it is connected.

The extended end of the mounting portion may be exposed to a side of the housing for connection to a transport carrier, and may form a vertically cut cross-section when separated from the transport carrier.

The mounting portion of the sub-power terminal may protrude from a side of the housing, and the mounting portion of each of the signal terminals may protrude from a side of the housing, with the extended end protruding longer than the mounting portion of each of the sub-power terminals.

The mounting portion 433 of each signal terminal 430 extends vertically downward from the extended end of the upper contact portion 432 and is exposed at the bottom of the housing 300, and the lower end is bent horizontally to protrude from the side of the housing 300. The lower contact portion 434 of each signal terminal 430 extends from the lower end of the first inner contact portion 431 in the direction of the second insertion protrusion 330 and is located at the bottom of the insertion groove 320.

The second inner contact portion 435 of each signal terminal 430 is bent upward and extended from the extended end of the lower contact portion 434, and is positioned perpendicular to the side of the second insertion protrusion 330.

In addition, a first contact portion 431a may protrude from the first inner contact portion 431 of each signal terminal 430, and a second contact portion 435a may protrude from the second inner contact portion 435.

The method for manufacturing a connector according to the third embodiment of the present invention is a method for manufacturing a connector for female-male coupling with a corresponding mating connector, and includes a step of moving each terminal to an assembly position, a step of insert molding, and a step of cutting.

First, the method for manufacturing a connector according to the third embodiment of the present invention involves a step of transporting the first carrier connection part of the main power terminal 410 to the first transfer carrier 10, the second carrier connection part of the sub power terminal 420 to the second transfer carrier 20, and the third carrier connection part of the signal terminal 430 to the third transfer carrier 30, all of which are connected to their respective assembly positions.

Next, the housings 100, 300 are insert molded onto the main power terminal 410, sub power terminal 420, and signal terminal 430 that have been transported to the assembly position, and the first carrier connection part, second carrier connection part, and third carrier connection part are cut off, respectively, and separated from the respective transport carriers.

Here, the sub-power terminal 420 is formed with a width wider than the signal terminal 430, and a plating layer may be formed on the cut surface of the first connecting portion, but not on the cut surfaces of the second connecting portion and the third connecting portion. In contrast, a plating layer may not be formed on the cut surfaces of the first connecting portion, the second connecting portion, and the third connecting portion.

Furthermore, each transport carrier may be a different type of transport carrier.

As a result, the present invention can increase the allowable current range by additionally installing a sub-power terminal 220 having a width relatively wider than each signal terminal 230, thereby ensuring stability when supplying power.

In addition, the present invention extends the mounting portions of the main power terminal 210, signal terminal 230, and sub power terminal 220 so that they protrude from the side of the housing 100 and connects them individually to the transfer carrier 10, so that each terminal can be moved individually during assembly and then insert molded, ensuring ease of assembly.

The above describes a specific embodiment of the connector of the present invention, but it is obvious that various modifications are possible without departing from the scope of the present invention.

Therefore, the scope of the present invention should not be limited to the above-described embodiment, but should be determined not only by the scope of the patent claims described below, but also by equivalents to the scope of the patent claims.

In other words, it should be understood that the above-described embodiments are illustrative in all respects and are not limiting, and the scope of the present invention is disclosed by the claims described below rather than the detailed description, and all modifications or variations derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
