Description

Resistance Built-in Joint Connector The present invention relates to a shielded ground joint connector equipped with a resistor inside. Eco-friendly vehicles are vehicles that utilize electric energy for all or part of the driving force required for driving. They are equipped with a battery and a motor, and use the electrical energy stored in the battery to rotate the motor, thereby providing the driving force necessary for driving. To this end, the eco-friendly vehicle is equipped with a charging inlet that periodically receives power from an external source, and a charging outlet connected to an external device is coupled to the charging inlet. At this time, high-voltage current is supplied to the charging inlet through the charging outlet. A charging connector is connected to the inlet, and to verify whether the charging connector is connected to the inlet, a resistor is provided at the PD terminal of the inlet to check whether the charging connector is connected. As shown in FIG. 1, the conventional charging inlet (1) is equipped with a resistance connector (2) and a joint connector (3) for high-voltage shielded wire grounding. This approach causes various problems, such as increased cost and weight due to the separate configuration of resistance and joint connectors, as well as increased labor costs for module manufacturers, making it necessary to find a solution to address these issues. The matters described above as background technology are intended only to enhance understanding of the background of the present invention and should not be construed as an acknowledgment that they constitute prior art already known to those skilled in the art.

FIG. 2 is a drawing illustrating a resistance-embedded joint connector according to an embodiment of the present invention. FIG. 3 is an exploded view of a resistance-embedded joint connector according to an embodiment of the present invention. FIG. 4 is a front view of the first busbar and the second busbar in a resistance-embedded joint connector according to an embodiment of the present invention. FIG. 5 is a drawing showing a second pin coupled to a second resistor coupling groove in a resistor-embedded joint connector according to an embodiment of the present invention. Figure 6 is an enlarged view of (A) of Figure 3. FIG. 7 is a drawing showing the application of a resistance-embedded joint connector to an electric vehicle charging inlet according to an embodiment of the present invention. The present invention is capable of various modifications and may have various embodiments, and specific embodiments are illustrated and described in the drawings. However, this is not intended to limit the invention to specific embodiments, and it should be understood that the invention includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention. Terms including ordinal numbers, such as “first,” “second,” etc., may be used to describe various components, but said components are not limited by said terms. These terms are used solely for the purpose of distinguishing one component from another. The term “and/or” is used to include any combination of the multiple items in question. For example, “A and/or B” means including all three cases, such as “A,” “B,” and “A and B.” When it is stated that one component is "connected" or "connected" to another component, it should be understood that while it may be directly connected or connected to that other component, there may also be other components in between. On the other hand, when it is stated that one component is "directly connected" or "directly connected" to another component, it should be understood that there are no other components in between. In the description of the embodiments, the statement that each layer (film), region, pattern, or structure is formed "on" or "under" the substrate, each layer (film), region, pad, or pattern includes both direct formation and formation through another layer. The criteria for "on" or "under" are based on the appearance depicted in the drawings for convenience and are used merely to indicate the relative positional relationship between components for convenience; they should not be understood as limiting the actual positions of the components. For example, "on B" merely indicates that B is depicted on A in the drawings unless otherwise stated or if, due to the attributes of A or B, A must be positioned on B. In actual products, B may be positioned under A, or B and A may be arranged side by side. Additionally, the thickness or size of each layer (film), region, pattern, or structure in the drawings may be modified for clarity and convenience of explanation, so they do not fully reflect the actual size. The terms used in this application are used merely to describe specific embodiments and are not in
