[0027] By referring to the detailed description and drawings of the embodiments, it is easier to understand the aspects of some embodiments of the present disclosure and the methods for realizing the aspects. The described embodiments are provided as examples so that the present disclosure will be detailed and complete, and will fully convey the aspects of the present disclosure to those skilled in the art. Accordingly, processes, elements and techniques that are redundant, irrelevant or unrelated to the description of the embodiments or are unnecessary for those of ordinary skill in the art to fully understand the aspects of the present disclosure can be omitted. Unless otherwise stated, the same reference numerals, characters or combinations thereof represent the same elements throughout the drawings and written descriptions, and therefore their repeated descriptions can be omitted.

[0028] The described embodiments may have various modifications and may be implemented in different forms, and should not be construed as being limited to the embodiments illustrated herein. The use of "can", "may" or "may not" when describing an embodiment corresponds to one or more embodiments of the present disclosure. The present disclosure includes all modifications, equivalents and alternatives within the scope of the ideas and techniques of the present disclosure. In addition, each feature of the various embodiments of the present disclosure may be combined with each other in part or in whole, and various interlocks and drives are technically possible. Each embodiment may be implemented independently of one another, or may be implemented together in an associated manner.

[0029] In the drawings, the relative sizes of elements, layers, and regions may be exaggerated for clarity and / or descriptive purposes. In addition, the use of cross-hatching and / or shading in the drawings is generally provided to clarify the boundaries between adjacent elements. As such, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for specific materials, material properties, dimensions, proportions, commonalities between illustrated elements, and / or any other features, attributes, characteristics, etc. of elements, unless otherwise specified.

[0030] It will be understood that when an element, layer, region, or component is referred to as being "formed on," "on" another element, layer, region, or component, "connected to," or "(operably or communicatively) coupled to" another element, layer, region, or component, it may be directly formed on, on, connected to, or coupled to another element, layer, region, or component, or indirectly formed on, on, connected to, or coupled to another element, layer, region, or component, such that there may be one or more intervening elements, layers, regions, or components. Additionally, this may collectively mean direct or indirect coupling or connection, as well as integral or non-integral coupling or connection. For example, when a layer, region, or component is referred to as being "electrically connected" or "electrically coupled" to another layer, region, or component, it may be directly electrically connected or electrically coupled to other layers, regions, and / or components, or there may be one or more intervening layers, regions, or components. The one or more intervening components may include switches, resistors, capacitors, and the like. In describing the embodiments, expressions of connection indicate electrical connection unless explicitly described as direct connection, and “directly connected / directly coupled” or “directly on” means that one component is directly connected or coupled to another component, or is on another component, without intervening components.

[0031] In addition, in this specification, when a part of a layer, film, zone, plate, etc. is formed on another part, the formation direction is not limited to the upper direction, but includes forming the part on the side surface or in the lower direction. On the contrary, when a part of a layer, film, zone, plate, etc. is formed "below" another part, this includes not only the case where the part is "directly under" another part, but also the case where there is another part between the part and the other part. At the same time, other expressions describing the relationship between parts, such as "between...", "immediately between..." or "adjacent to..." and "directly adjacent to..." can be interpreted similarly. It will be understood that when an element or layer is referred to as "between" two elements or layers, it can be the only element or layer between the two elements or layers, or one or more intervening elements or layers may also be present.

[0032] For the purposes of this disclosure, expressions such as "at least one of..." or "any one of..." or "one or more of..." when following a list of elements modify the entire list of elements, rather than the individual elements in the list. For example, "at least one of X, Y, and Z," "at least one of X, Y, or Z," "at least one selected from the group consisting of X, Y, and Z," and "at least one selected from the group consisting of X, Y, or Z" may be interpreted as any combination of only X, only Y, only Z, two or more of X, Y, and Z (such as XYZ, XYY, YZ, and ZZ), or any variation thereof. Similarly, the expressions "at least one of A and B" and "at least one of A or B" may include A, B, or A and B. As used herein, "or" generally means "and / or," and the term "and / or" includes any and all combinations of one or more of the associated listed items. For example, the expression "A and / or B" may include A, B, or A and B. Similarly, expressions such as “at least one of,” “a plurality of,” “one of,” and other prepositional phrases when preceding or following a list of elements modify the entire list of elements and do not modify the individual elements of the list.

[0033] It will be understood that although the terms "first", "second", "third", etc. can be used in this article to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms do not correspond to a specific order, position or advantage, and are only used to distinguish an element, member, component, region, area, layer, section or part from another element, member, component, region, area, layer, section or part. Therefore, the first element, component, region, layer or section described below can be referred to as the second element, component, region, layer or section without departing from the spirit and scope of the present disclosure. Describing an element as a "first" element may not require or imply the presence of a second element or other elements. The terms "first", "second", etc. can also be used in this article to distinguish between different categories or different groups of elements. For the sake of brevity, the terms "first", "second", etc. can respectively represent "first class (or first group)", "second class (or second group)", etc.

[0034] In the example, the x-axis, y-axis and / or z-axis are not limited to three axes in a rectangular coordinate system and can be interpreted in a broader sense. For example, the x-axis, y-axis and z-axis can be perpendicular to each other, or can represent different directions that are not perpendicular to each other. The same applies to the first, second and / or third directions.

[0035] The terms used herein are only used for the purpose of describing the embodiments and are not intended to limit the present disclosure. As used herein, the singular form "one" is also intended to include the plural form, and the plural form is also intended to include the singular form, unless the context clearly states otherwise. It will be further understood that the terms "include", "have" and "comprise" when used in this specification clearly specify the presence of stated features, integers, steps, operations, elements and / or parts, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, parts and / or their groups.

[0036] As used herein, the terms "substantially", "about", "roughly" and similar terms are used as approximate terms rather than terms of degree, and are intended to illustrate the inherent deviations of measured or calculated values ​​that will be recognized by those of ordinary skill in the art. For example, "substantially" may include a range of + / - 5% of the corresponding value. "About" or "roughly" as used herein include the stated values ​​and mean within an acceptable range of deviations of a particular value determined by those of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "about" may mean within one or more standard deviations, or within ±30%, 20%, 10%, 5% of the stated value. In addition, "may" is used when describing embodiments of the present disclosure to refer to "one or more embodiments of the present disclosure".

[0037] In some embodiments, known structures and devices may be described in drawings associated with one or more functional blocks (e.g., block diagrams), units and / or modules to avoid unnecessary blurring of various embodiments. Those skilled in the art will appreciate that such blocks, units and / or modules are physically implemented by logic circuits, separate components, microprocessors, hard-wired circuits, storage elements, line connections, and other electronic circuits. This can be formed using semiconductor-based manufacturing techniques or other manufacturing techniques. Blocks, units and / or modules implemented by microprocessors or other similar hardware can be programmed and controlled using software to perform the various functions discussed herein, optionally driven by firmware and / or software. In addition, each block, unit and / or module may be implemented by dedicated hardware or by a combination of dedicated hardware that performs certain functions and a processor (e.g., one or more programmed microprocessors and associated circuits) that performs functions different from dedicated hardware. In addition, in some embodiments, blocks, units and / or modules may be physically divided into two or more interacting separate blocks, units and / or modules without departing from the scope of this disclosure. Additionally, in some embodiments, blocks, units and / or modules may be physically combined into more complex blocks, units and / or modules without departing from the scope of the present disclosure.

[0038] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as those commonly understood by those of ordinary skill in the art to which the present disclosure belongs. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and / or this specification, and should not be interpreted in an idealized or overly formal sense, unless explicitly defined as such herein.

[0039] Hereinafter, a connecting device according to an embodiment will be described in detail with reference to the accompanying drawings.

[0040] Figure 1 A connection device according to an embodiment is schematically illustrated.

[0041] refer to Figure 1 , a connecting device 1a according to an embodiment may include a first connector 10a and a second connector 20a.

[0042] The first connector 10a is a male connector used as a plug. The first connector 10a may include a connector body 11 and connection terminals (eg, first connection terminals) 12 (hereinafter referred to as "plug terminals") protruding from one surface of the connector body 11 in one direction (x direction).

[0043] The second connector 20a is a female connector used as a socket. The second connector 20a may include a connector body 21 and a connection terminal (eg, second connection terminal) 22 (hereinafter referred to as a “socket terminal”) located inside the connector body 21.

[0044] If the first connector 10a and the second connector 20a are connected, the plug terminal 12 can be inserted and connected to the socket terminal 22. The plug terminal 12 may have a pin or a columnar conductor protruding in the insertion direction (x direction). The socket terminal 22 may include or define a hollow portion extending along the insertion direction (x direction) of the plug terminal 12, and have a cylindrical shape or a polygonal column shape (such as a triangular prism or a quadrangular prism shape).

[0045] The plug terminal 12 and the socket terminal 22 may be formed of conductors for electrical connection. If the plug terminal 12 is inserted into the hollow portion of the socket terminal 22, the outer wall of the plug terminal 12 contacts the inner wall of the hollow portion of the socket terminal 22, and the plug terminal 12 and the socket terminal 22 may be electrically connected to each other. In more detail, when the plug terminal 12 is fully inserted into the hollow portion of the socket terminal 22, the outer wall of the plug terminal 12 contacts the inner wall of the hollow portion of the socket terminal 22, that is, contacts the first conductor 221 and the second conductor 222, so that the plug terminal 12 and the socket terminal 22 are electrically connected to each other.

[0046] The first connector 10a may further include a wire (e.g., a first wire) 13 electrically connected to the plug terminal 12. The second connector 20a may further include a wire (e.g., a second wire) 23 electrically connected to the socket terminal 22. The first connector 10a may be connected to a battery or a load that receives power from the battery through the wire 13. The second connector 20a may be connected to a battery or a load that receives power from the battery through the wire 23.

[0047] The socket terminal 22 may include a plurality of conductors (e.g., a first conductor and a second conductor) 221, 222 spaced apart from each other along the insertion direction (x direction) of the plug terminal 12 to limit surge current, and a resistor 223 connected between the plurality of conductors 221, 222. In other words, the conductors 221, 222 are not in direct electrical contact. The conductors 221, 222 are connected via the resistor 223. The conductor 221 may be located at an outer position of the hollow portion, i.e., at an entrance side of the second connector 20a into which the plug terminal 12 is inserted. The conductor 222 may be located at an inner position of the hollow portion.

[0048] Figure 2 For illustrative purposes Figure 1 A perspective view of the socket terminal 22 is shown.

[0049] refer to Figure 2, the conductors 221, 222 may have a ring, a cylindrical, or a polygonal column shape (such as a triangular prism or a quadrangular prism shape), and may include a hollow portion into which the plug terminal 12 is inserted. The conductor 221 may be located on the entrance side of the second connector 20a into which the plug terminal 12 is inserted. The conductor 222 may be located in the second connector 20a at a position that can contact the plug terminal 12 when the plug terminal 12 is inserted into the socket terminal 22 (e.g., at a predetermined depth or more).

[0050] Return to reference Figure 1 The second connector 20a may further include an elastic structure (eg, a first elastic structure) 24 between the conductors 221 , 222 of the socket terminal 22 to ensure insulation between the conductors 221 , 222 and delay or slow down the insertion speed of the plug terminal 12 .

[0051] The elastic structure 24 is located between the conductors 221 and 222 and may be made of an insulating material to ensure insulation between the conductors 221 and 222. The elastic structure 24 may protrude from the connector body 21 of the second connector 20a (for example, in a predetermined direction (y direction)) and may protrude toward the hollow portion of the socket terminal 22. The elastic structure 24 has a protruding height that is reduced by the insertion force of the plug terminal 12 and may provide an elastic force that resists the insertion force of the plug terminal 12. Figure 1 As an example, the elastic structure 24 may include an insulator 241 located between the conductors 221 , 222 and a spring device 242 located between the insulator 241 and the connector body 21 for applying elastic force to the insulator 241 .

[0052] Figure 3A to Figure 3C 1 is a diagram for describing a process of connecting the first connector 10 a and the second connector 20 a .

[0053] refer to Figure 3A In the initial stage of connecting the plug terminal 12 and the socket terminal 22, the plug terminal 12 may be first inserted into the conductor 221 of the socket terminal 22. In one or more embodiments, an inrush current limiting circuit including a resistor 223 is formed between the plug terminal 12 and the conductor 222, and the inrush current may be suppressed by the resistor 223.

[0054] refer to Figure 3B Thereafter, if the insertion of the plug terminal 12 continues, the end of the plug terminal 12 may contact the elastic structure 24. The elastic structure 24 provides an elastic force against the insertion force of the plug terminal 12, which may delay or slow down the insertion of the plug terminal 12.

[0055] refer to Figure 3C, thereafter, if the insertion of the plug terminal 12 continues, the protruding height of the elastic structure 24 decreases, thereby allowing the plug terminal 12 to move over the elastic structure 24 toward the conductor 222. Finally, the plug terminal 12 can directly contact the conductor 222, thereby completing the connection between the first connector 10a and the second connector 20a. Since the plug terminal 12 is in direct contact with the conductor 222, current can flow directly between the plug terminal 12 and the conductor 222 without passing through the surge current limiting circuit.

[0056] As described above, the connection device 1a can automatically perform initial charging in the process of connecting the first connector 10a and the second connector 20a, thereby limiting the inrush current. In one or more embodiments, due to the elastic structure 24, the insertion of the plug terminal 12 is delayed or blocked, thereby ensuring sufficient initial charging time.

[0057] Return to reference Figure 1 In order to ensure insulation between the conductors 221 , 222 of the socket terminal 22 , the second connector 20 a may further include an insulator 25 inserted into a space between the conductors 221 , 222 where the elastic structure 24 is not arranged.

[0058] although Figure 1 An example is shown in which the second connector 20 a includes only one elastic structure 24 , but the present disclosure is not limited thereto. In one or more other embodiments, the second connector 20 a may include a plurality of elastic structures 24 between the conductors 221 , 222 of the socket terminal 22 .

[0059] Figure 4 and Figure 5 An example in which the connection device 1 a according to the embodiment is applied to electrical connection of a battery is illustrated.

[0060] refer to Figure 4 and Figure 5 The connection device 1a can be used to electrically connect one of the output terminals of the battery 2 (e.g., the positive output terminal) and the load 3. For example, the wires 13, 23 of the first connector 10a and the second connector 20a of the connection device 1a can be electrically connected to the output terminal of the battery 2 and the load 3, respectively.

[0061] In one or more embodiments, if the first connector 10a and the second connector 20a of the connection device 1a are connected, electrical connection may be made between the output terminal of the battery 2 and the load 3 through the connection device 1a.

[0062] refer to Figure 4 , the electrical connection between the remaining one of the output terminals of the battery 2 (e.g., the negative output terminal) and the load 3 may also be provided using the connection device 1a. In one or more embodiments, reference Figure 5, the electrical connection between the remaining one of the output terminals of the battery 2 (eg, the negative output terminal) and the load 3 may also be provided using the connection device 4 that does not include an inrush current limiting resistor.

[0063] In one or more embodiments, the connection device 1 a may be used not only for electrical connection between the battery 2 and the load 3 , but also for other types of electrical connection where surge current may occur, such as electrical connection between batteries 2 .

[0064] Figure 6 A connection device according to one or more other embodiments is schematically illustrated.

[0065] refer to Figure 6 In the connection device 1b according to one or more other embodiments, the first connector 10b may include a plurality of plug terminals (e.g., a first connection terminal and a third connection terminal) 12a, 12b protruding from the connector body 11 in one direction (x direction). In one or more embodiments, the second connector 20b may include a plurality of socket terminals (e.g., a second connection terminal and a fourth connection terminal) 22a, 22b located inside the connector body 21. Each plug terminal 12a, 12b may be arranged in a manner similar to the reference Figure 1 The pin terminal 12 described above is formed in the same structure, and each of the socket terminals 22a, 22b can be formed in the same structure as that of the reference Figure 1 and Figure 2 The same structure as that of the socket terminal 22 described above is formed. In the following description, overlapping descriptions of the plug terminal 12 and the socket terminal 22 of the connection device 1a according to the embodiment may be omitted.

[0066] If the first connector 10b and the second connector 20b are connected, the plug terminal 12a may be inserted into and electrically connected to the socket terminal 22a, and the plug terminal 12b may be inserted into and electrically connected to the socket terminal 22b.

[0067] The first connector 10b may further include wires (e.g., first and third wires) 13a, 13b electrically connected to the plug terminals 12a, 12b, respectively. The second connector 20b may further include wires (e.g., second and fourth wires) 23a, 23b electrically connected to the socket terminals 22a, 22b, respectively. The first connector 10b may be connected to a battery or a load receiving power from the battery through the wires 13a, 13b. The second connector 20b may be connected to a battery or a load receiving power from the battery through the wires 23a, 23b.

[0068] refer to Figure 2The socket terminal 22 may include a plurality of conductors 221, 222 spaced apart from each other along the insertion direction (x direction) of the corresponding plug terminals 12a, 12b and a resistor 223 connected between the plurality of conductors 221, 222. In the following description, for convenience of explanation, reference will be made to Figure 2 The reference numerals in 0 describe each constituent element of each socket terminal 22a, 22b.

[0069] The second connector 20b may further include a plurality of elastic structures (e.g., a first elastic structure and a second elastic structure) 24a, 24b. Each elastic structure 24a, 24b may be located between the conductors (e.g., the first conductor and the second conductor or the third conductor and the fourth conductor) 221, 222 of the corresponding socket terminals 22a, 22b. Each of the elastic structures 24a, 24b may be made of an insulating material to ensure insulation between the conductors 221, 222 of the corresponding socket terminals 22a, 22b. Each elastic structure 24a, 24b may protrude from the connector body 21 of the second connector 20b toward the hollow portion of the corresponding socket terminals 22a, 22b (e.g., in a predetermined direction (y direction)). Each elastic structure 24a, 24b has a protruding height that is reduced due to the insertion force of the corresponding plug terminals 12a, 12b, and may provide an elastic force that resists the insertion force of the corresponding plug terminals 12a, 12b. Each elastic structure 24 may include an insulator 241 located between the conductors 221 , 222 and a spring device 242 located between the insulator 241 and the connector body 21 for applying elastic force to the insulator 241 .

[0070] In the initial stage of connecting the first connector 10b and the second connector 20b, each plug terminal 12a, 12b can be first inserted into the conductor 221 of the corresponding socket terminal 22a, 22b, respectively. In one or more embodiments, an inrush current limiting circuit including a resistor 223 is formed between each plug terminal 12a, 12b and the conductor 222 of the corresponding socket terminal 22a, 22b, and the inrush current can be suppressed by the resistor 223.

[0071] Thereafter, if the insertion of the plug terminals 12a, 12b continues, the end of each plug terminal 12a, 12b may contact the corresponding elastic structure 24a, 24b. Each elastic structure 24a, 24b provides an elastic force against the insertion force of the plug terminals 12a, 12b, which may partially delay or slow down the insertion of the plug terminals 12a, 12b.

[0072] Thereafter, if the insertion of the plug terminals 12a, 12b continues, the protruding height of each of the elastic structures 24a, 24b decreases, thereby allowing the plug terminals 12a, 12b to move over the elastic structures 24a, 24b toward the conductor 222 of the corresponding socket terminals 22a, 22b. Finally, each of the plug terminals 12a, 12b can directly contact the conductor 222 of the corresponding socket terminals 22a, 22b, thereby completing the connection between the first connector 10b and the second connector 20b. Since each of the plug terminals 12a, 12b is in direct contact with the conductor 222 of the corresponding socket terminals 22a, 22b, the current between each of the plug terminals 12a, 12b and the conductor 222 of the corresponding socket terminals 22a, 22b can flow directly therebetween without passing through the surge current limiting circuit.

[0073] exist Figure 6 In the embodiment, the resistor 223 and the elastic structure 24 for limiting surge current are located on all the socket terminals 22a, 22b of the second connector 20b, but the embodiment is not limited thereto.
