Description

Technical Field

[0001] The present invention relates to a connector, and more particularly to a connector that can be mounted on a substrate and a connector assembly including the same. Background Art

[0002] Generally, connectors are provided in various electronic devices for electrical connection. For example, connectors can be provided in electronic devices such as mobile phones, computers, tablet computers, etc., and electrically connect various components provided in the electronic devices to each other. Such connectors are composed of an insulating body and a plurality of contacts, wherein the insulating body has a predetermined insulation property and is placed on a substrate, and the plurality of contacts are arranged on the insulating body in parallel with each other along one direction.

[0003] At this time, as a solution for increasing the number of contacts of the connector, it is possible to consider increasing the size of the insulating body for accommodating the contacts, or densely arranging the contacts on the insulating body by reducing the distance (ie, pitch) between the contacts.

[0004] However, if the first of the above-mentioned solutions is adopted for an existing connector, the size of the insulating body may become excessively long or large as the number of contacts increases, thereby possibly causing the following problems: limited freedom in substrate circuit design, manufacturing defects due to bending, and reduced overall strength of the connector.

[0005] If the second solution is adopted for the conventional connector, there is a problem that the insulation performance between the two contacts cannot be ensured as the portions where the adjacent contacts are joined to the substrate come close to each other, and a short circuit may occur.

[0006] Therefore, there is an urgent need to develop a connector that can minimize the pitch and configure a larger number of contacts in a limited space without causing the aforementioned insulation problem. Summary of the invention

[0010] Another object of the present invention is to provide a connector with higher rigidity (or strength) and a connector assembly including the same.

[0056] The words or terms used in this specification and claims should not be limited to the usual or dictionary meanings, but should be interpreted as meanings and concepts that are consistent with the technical ideas of the present invention based on the principle that the inventor appropriately defines terms and concepts in order to explain his invention in the best way.

[0057] In this specification, it should be understood that the terms "including" or "having" etc. are intended to indicate the existence of features, numbers, steps, actions, constituent elements, parts, or combinations thereof recorded in the specification, without excluding in advance the possibility of the existence or addition of one or more other features, numbers, steps, actions, constituent elements, parts, or combinations thereof.

[0058] If a certain component is described as existing in the “front”, “rear”, “above” or “below” of another component, then unless otherwise specified, this includes not only the case where the component is in direct contact with the other component and is disposed in the “front”, “rear”, “above” or “below” of the other component, but also the case where another component is disposed between them. Furthermore, unless otherwise specified, a component “connected to” another component includes not only the case where the components are directly connected to each other, but also the case where the components are indirectly connected to each other.

[0059] Figure 1 and Figure 2 The following are three-dimensional views of a connector according to an embodiment of the present invention viewed from different angles. Figure 3 FIG. 4 is a top view of a connector according to an embodiment of the present invention. Figure 4 FIG. 4 is a top view of a PCB pattern formed between a connector and a substrate according to an embodiment of the present invention. Figure 5 is along Figure 3 Cross-sectional view taken along section line Ⅰ-Ⅰ. Figure 6 This is a perspective view of a first contact of a connector according to an embodiment of the present invention as viewed from above. Figure 7 (a) and Figure 7 (b) is a stereoscopic view of the second contact member according to an embodiment of the present invention observed from different angles.

[0060] In the following, when observing the drawings, the first direction is defined as the X-axis direction, the second direction is defined as the Y-axis direction, and the third direction is defined as the Z-axis direction. At this time, in this specification, the purpose of introducing the first direction to the third direction and the coordinate axis (XYZ axis) is only to explain the relative positions between the components, and does not limit the absolute positions of each component.

[0061] In this specification, extending in a predetermined direction means extending to have a length component along the direction. For example, since extending in a direction inclined to the X-axis has a length component in a direction parallel to the X-axis, extending in the X-axis direction includes extending in a direction inclined to the X-axis.

[0062] Reference Figure 1 and Figure 2 The connector of one embodiment of the present invention may be a plug connector 10. The plug connector 10 may be mounted on a substrate (not shown) and connected to another connector (e.g., a socket connector 20) mounted on another substrate. Figure 7 As shown in FIG. 1 , the shapes of the substrates are matched and combined. Thus, the circuit of the substrate on which the plug connector 10 is mounted can be electrically connected (or energized) to the circuit of the substrate on which another connector is mounted.

[0063] According to the present embodiment, the plug connector 10 may include an insulating body 100, a first contact 200, a second contact 300, and a pressing structure 400. The insulating body 100 is a structure for providing a base on which other structures of the plug connector 10 can be configured. In this case, the insulating body 100 may include a material having a prescribed insulating property to achieve electrical insulation from other structures.

[0064] Reference Figures 1 to 4 In this embodiment, the insulating body 100 may include a bottom 110 , an outer supporting wall portion 120 , a pressing and holding wall portion 130 , and an inner supporting wall portion 140 .

[0065] According to the present embodiment, the bottom portion 110 may be provided as a plate-shaped member extending in the X-axis direction and having a predetermined width in the Y-axis direction. The bottom surface of the bottom portion 110 may be placed on one side of the substrate, thereby supporting the plug connector 10 as a whole.

[0066] At this time, according to this embodiment, a hole-shaped inspection window 111 formed along the Z-axis direction may be provided on the bottom 110 . In this embodiment, a plurality of inspection windows 111 may be provided corresponding to a plurality of first contact members 200 .

[0067] Furthermore, some of the inspection windows 111 may be arranged spaced apart from each other along the X-axis direction on the side of any one of the pair of outer support walls 140. Similarly, the remaining inspection windows 111 may be arranged spaced apart from each other along the X-axis direction on the side of the other outer support wall 140. That is, the inspection windows 111 may be formed in two rows along the X-axis direction corresponding to the arrangement of the first contact members 200 described later.

[0068] Thus, the first substrate mounting portion 220 of the first contact 200 coupled to the outer supporting wall portion 140 can be observed through the inspection window 111 , so that the mounting state between the first substrate mounting portion 220 and the substrate can be inspected.

[0069] Furthermore, as described later, the second contact 300 is disposed between the first contacts 200 adjacent to each other in the X-axis direction, so that a predetermined distance can be ensured between the inspection windows 111 adjacent to each other in the X-axis direction, thereby minimizing the reduction in strength of the bottom 110 caused by forming the inspection windows 111 .

[0070] On the other hand, in the present embodiment, the plurality of inspection windows 111 are configured to respectively check one first substrate mounting portion 220 , but may be provided in a form extending long in the X-axis direction so that two or more first substrate mounting portions 220 can be checked through one inspection window 111 .

[0071] In addition, the bottom 110 of this embodiment may be provided with a corresponding groove 113 cut along the Z-axis direction. The corresponding groove 113 may relieve the constraint between the second contact 300 and the insulating body 100, so that the elastic contact portion 320 of the second contact 300 can move more smoothly.

[0072] To this end, the corresponding grooves 113 of the present embodiment may be provided in plural numbers corresponding to the number of the plural second contacts 300. Furthermore, a portion of the plural second contacts 300 may be arranged in a spaced relationship along the X-axis direction on one side of the inner support wall portion 140 described later, and the remaining portion may be arranged in a spaced relationship along the X-axis direction on the other side of the inner support wall portion 140. That is, the plural corresponding grooves 113 may be formed in two rows along the X-axis direction corresponding to the arrangement of the second contacts 300 described later.

[0073] More specifically, in this embodiment, the corresponding groove 113 can be connected to the groove 143 of the inner supporting wall portion 140 described later. Thus, the corresponding groove 113 can make the portion where the second central connecting portion 330 of the second contact 300 is connected to the elastic contact portion 320 exposed to the outside (i.e., relieving the constraint). Therefore, the elastic contact portion 320 of the second contact 300 can easily perform elastic movement with external force.

[0074] In addition, as described later, since the first contact member 200 is arranged between the second contact members 300 adjacent to each other along the X-axis direction, a specified distance can be ensured between the corresponding grooves 113 adjacent to each other along the X-axis direction, thereby minimizing the weakening of the bottom 110 caused by forming the corresponding grooves 113.

[0075] On the other hand, there is no particular limitation on the shape of the corresponding groove 113 , as long as a specified space can be provided so that the portion where the elastic contact portion 320 and the second central connecting portion 330 are connected is not recessed in the bottom 110 .

[0076] Refer again Figures 1 to 4 In this embodiment, an outer supporting wall portion 120, a pressing and holding wall portion 130, and an inner supporting wall portion 140 may be provided on the upper side of the bottom portion 110. The outer supporting wall portion 120 may be configured to support the contact members 200 and 300 described later. To this end, the outer supporting wall portion 120 may protrude from the top surface of the bottom portion 110 toward the positive direction of the Z axis and extend long along the X axis direction.

[0077] At this time, the outer supporting wall portions 120 of this embodiment may be provided as a pair and arranged at a predetermined distance in the Y-axis direction. In other words, the pair of outer supporting wall portions 120 may be provided as a pair of rod-shaped members extending parallel to each other in the X-axis direction.

[0078] Hereinafter, of the two side surfaces 122 and 124 of the outer supporting wall portion 120 in the Y-axis direction, the side surface facing the inner supporting wall portion 140 described later is defined as a first side surface 122 , and the side surface opposite to the first side surface 122 is defined as a second side surface 124 .

[0079] On the other hand, according to the present embodiment, a compression and holding wall portion 130 may be provided on the X-axis direction side portions of the pair of outer supporting wall portions 120. The compression and holding wall portion 130 may increase the overall rigidity of the insulating body 100 by supporting the ends of the outer supporting wall portions 120. Such a compression and holding wall portion 130 may be provided as a pair and each is provided on both sides of the pair of outer supporting wall portions 120 in the X-axis direction.

[0080] In the present embodiment, the compression and holding wall portion 130 may be provided as a block-shaped member extending in the Y-axis direction so as to connect the X-axis direction ends of the pair of outer supporting wall portions 120 to each other.

[0081] Refer again Figures 1 to 4 In this embodiment, an inner support wall portion 140 may be provided between the pair of outer support wall portions 120, and the inner support wall portion 140 protrudes from the bottom 110 toward the positive direction of the Z axis. The inner support wall portion 140 may match the shape of a portion of another connector coupled to the plug connector 10, thereby performing the function of increasing the coupling force of the two connectors.

[0082] In the present embodiment, the inner supporting wall portion 140 may be provided as a rod-shaped member extending in parallel with the outer supporting wall portion 120. At this time, the inner supporting wall portion 140 may have a length slightly shorter in the X-axis direction than the outer supporting wall portion 120. Thus, the inner supporting wall portion 140 may be surrounded by a pair of outer supporting wall portions 120 and a pair of compression and holding wall portions 130.

[0083] In this embodiment, the inner support wall portion 140 is used to be coupled to another connector, such as the socket connector 20 ( Figure 8 A pair of inner support wall portions 540 (shown in Figure 8 The composition between the two is shown in FIG.

[0084] As an example, the inner support wall portion 140 can be coupled to the socket connector 20 ( Figure 8 A pair of inner support wall portions 540 (shown in Figure 8 To this end, the inner support wall portion 140 may have a socket connector 20 ( Figure 8 The shape corresponding to the combined space 511 is shown in FIG.

[0085] On the other hand, in this embodiment, a groove 143 may be provided on the side surface 142 of the inner supporting wall portion 140 facing the Y-axis direction. Such a groove 143 may provide a space for the elastic contact portion 320 of the second contact member 300 to perform elastic motion while allowing the elastic contact portion 320 to be protected by the inner supporting wall portion 140 from external influences.

[0086] To this end, a plurality of grooves 143 may be provided corresponding to the plurality of second contacts 300. Furthermore, a portion of the plurality of grooves 143 may be arranged in a spaced relationship along the X-axis direction on any one of the two side surfaces 142, and the remaining portion may be arranged in a spaced relationship along the X-axis direction on the other side surface 142. That is, the plurality of grooves 143 may be formed in two rows on the two side surfaces 142 of the inner support wall portion 140 corresponding to the arrangement of the second contacts 300 described later.

[0087] At this time, as described later, in this embodiment, a first contact member 200 is arranged between adjacent second contact members 300 along the X-axis direction, so that a specified distance can be ensured between adjacent grooves 143 along the X-axis direction, thereby minimizing the weakening of the strength of the inner support wall portion 140 caused by forming the grooves 143.

[0088] As shown in the figure, the groove 143 can be formed to be recessed toward the inner side of the inner support wall portion 140. In addition, the groove 143 can extend in the Z-axis direction, and both sides of the extension direction are open to the outside. However, there is no particular limitation on the shape of the groove 143, as long as it can provide a movable space so that the elastic contact portion 320 can perform elastic movement and can protect the elastic contact portion 320.

[0089] On the other hand, the insulating body 100 can be integrally formed by injection molding, but is not limited thereto. Also, the shape of the insulating body 100 is not particularly limited, as long as a base capable of arranging other structures can be provided, and various deformations can be made as needed, such as partially bending.

[0090] Next, refer to Figures 4 to 6 , the first contact 200 and the second contact 300 of the plug connector 10 of this embodiment are described. Figure 4 and Figure 5 The first contact member 200 of this embodiment can be provided as a fixed terminal in the form of a conductive and curved metal sheet. At this time, the first contact member 200 of this embodiment can be provided in plural and spaced apart along the X-axis direction at each of the pair of outer support walls 120 .

[0091] In this embodiment, the first contact 200 may include a first outer coupling portion 210, a first substrate mounting portion 220, and a carrier connecting portion 230. First, the first outer coupling portion 210 may include a first outer contact portion 212, a first inner contact portion 214, and a first outer connecting portion 216, and is coupled to the outer supporting wall portion 140 of the insulating body 100.

[0092] According to the present embodiment, the first outer contact portion 212 may extend in the Z-axis direction. Furthermore, the first outer contact portion 212 may be combined with the second side surface 124 of the outer supporting wall portion 140 as a part of the side surface to be exposed to the outside. Similarly, the first inner contact portion 214 may extend in the Z-axis direction and be combined with the first side surface 122 of the outer supporting wall portion 120 as a part of the side surface to be exposed to the outside.

[0093] As described above, the first contact piece 200 of this embodiment is configured such that the first inner contact portion 214 and the first outer contact portion 212 are exposed on both side surfaces of the outer support wall portion 120, so that double contact with the contact piece of another connector can be achieved and maintained based on the supporting force of the outer support wall portion 120.

[0094] Next, in this embodiment, the first outer connecting portion 216 may connect the upper end of the first inner contact portion 214 and the upper end of the first outer contact portion 212. At this time, the first outer connecting portion 216 may be combined with the top surface of the outer supporting wall portion 120 to expose the top surface upward.

[0095] On the other hand, in the present embodiment, the first substrate mounting portion 220 may be connected to the first inner contact portion 214 . The first substrate mounting portion 220 may extend from a lower end portion of the first inner connecting portion 214 toward the inner supporting wall portion 140 .

[0096] As shown in the figure, the first substrate mounting portion 220 may extend along the Y-axis direction. However, there is no particular limitation on the extending direction of the first substrate mounting portion 220 , as long as the end of the first substrate mounting portion 220 faces the inner supporting wall portion 140 .

[0097] At this time, in this embodiment, at least a portion of the first substrate mounting portion 220 can be disposed in the inspection window 111 so as to be observed through the inspection window 111 of the bottom 110 . In the illustrated embodiment, an end of the first substrate mounting portion 220 is disposed in the inspection window 111 .

[0098] On the other hand, the first substrate mounting portion 220 may be configured to be mounted on the substrate on which the plug connector 10 is mounted. For example, the first substrate mounting portion 220 may be mounted on the substrate by a soldering process or a welding process. In this case, a prescribed PCB pattern may be interposed between the first substrate mounting portion 220 and the substrate for combining them.

[0099] Next, in this embodiment, a carrier connection portion 230 may be connected to the first outer connection portion 212. The carrier connection portion 230 may extend from the lower end of the first outer connection portion 212 in a direction opposite to the first substrate mounting portion 220. In other words, the carrier connection portion 230 may extend toward the outside of the insulation body 100.

[0100] As shown in the figure, the carrier connection portion 230 may extend along the Y-axis direction. However, there is no particular limitation on the extension direction of the carrier connection portion 230 , as long as the end of the carrier connection portion 230 faces the direction opposite to the end of the first substrate mounting portion 220 .

[0101] At this time, the side surface 232 of the carrier connection part 230 in the extension direction may have a predetermined gold plating layer L. Thus, the side surface 232 may not be exposed to the outside. However, the extension end surface 234 of the carrier connection part 230 may not have the gold plating layer L and may be exposed to the outside.

[0102] This is because the carrier connection portion 230 of the present embodiment can perform the function of connecting the carrier and the first contact 200 , but in the manufacturing process of the plug connector 10 , the carrier connection portion 230 may be cut off in order to separate the first contact 200 and the carrier from each other.

[0103] In this case, the carrier may be an intermediate member used to fix the positions of the contacts 200 and 300 in the manufacturing process of the plug connector 10. Therefore, the end surface 234 of the carrier connection portion 230 is formed as a cut surface, and the gold plating layer L may not be provided on such an end surface 234.

[0104] On the other hand, referring again Figure 5 In this embodiment, the width w1 of the first inner contact portion 214 in the X-axis direction may be greater than the width w2 of the first outer contact portion 212 in the X-axis direction. Thus, the first inner contact portion 214 may contact and be more strongly combined with the outer support wall portion 120 with a wider area, and may be electrically connected (or energized) with a contact of another connector with a wider area.

[0105] Next, refer to Figure 4 and Figure 6In this embodiment, the second contact member 300 can be provided as a fully movable terminal in the form of a conductive and bent metal sheet. In this case, a plurality of second contact members 300 can be provided, and each is arranged between adjacent first contact members 200 along the X-axis direction. In other words, the first contact member 200 and the second contact member 300 can be alternately arranged along the X-axis direction.

[0106] The second contact 300 of the present embodiment may include a second outer coupling portion 310, an elastic contact portion 320, a central connection portion 330, and a second substrate mounting portion 340. In addition, the second outer coupling portion 310 may include a second outer contact portion 312, a second inner contact portion 314, and a second outer connection portion 316, and is coupled to the outer support wall portion 120.

[0107] First, the second outer contact portion 312 of the present embodiment may extend along the Z-axis direction. Furthermore, the second outer contact portion 312 may be coupled to the second side surface 124 of the outer supporting wall portion 140 so that a portion of the side surface is exposed to the outside. Similarly, the second inner contact portion 314 may extend along the Z-axis direction and be coupled to the first side surface 122 of the outer supporting wall portion 140 so that a portion of the side surface is exposed to the outside.

[0108] As described above, the second contact piece 300 of this embodiment is combined into a second inner contact portion 314 and a second outer contact portion 312 exposed on both side surfaces of the outer support wall portion 120, so that double contact with the contact piece of another connector can be achieved and maintained based on the supporting force generated by the outer support wall portion 120.

[0109] In addition, a second central connection portion 330 may be connected to the lower end of the second inner contact portion 314. The second central connection portion 330 may extend along the Y-axis direction and be coupled to the top surface of the bottom portion 110. At this time, the second central connection portion 330 may be configured such that the top surface is exposed to the upper side of the bottom portion 110, but is not limited thereto. It may function as a portion electrically connected (or energized) to a contact of another connector.

[0110] On the other hand, in this embodiment, the first direction width w3 of the second outer contact portion 312 may be greater than the first direction width w4 of the second inner contact portion 314. Thus, the second outer contact portion 312 may contact and strongly combine with the outer support wall portion 120 with a wider width, and may be electrically connected (or energized) with a contact of another connector with a wider area.

[0111] Refer again Figure 3, if the positional relationship between the first contact 200 and the second contact 300 is considered together, the second inner contact portion 314 having a relatively narrow width w4 is arranged between the first inner contact portions 214 having a relatively wide width w1 on the first side surface 122 of the outer supporting wall portion 120. Also, the second outer contact portion 314 having a relatively wide width w3 is arranged between the first outer contact portions 212 having a relatively narrow width w2 on the second side surface 124 of the outer supporting wall portion 120.

[0112] As described above, in the connector of this embodiment, the first contacts 200 and the second contacts 300 having different widths are alternately arranged, and the distance between the contacts is constant. Therefore, the connector can have uniform strength as a whole and improve the strength of the connector.

[0113] In addition, in this embodiment, the second central connection portion 330 of the second contact 300 is disposed between the adjacent inspection windows 111 in the X-axis direction. The second central connection portion 330 can enhance the strength of the portion between the adjacent inspection windows 111.

[0114] In addition, a portion of the first contact 200 is disposed between the corresponding grooves 113 and 143 adjacent to each other in the X-axis direction. The first contact 200 as described above can enhance the strength of the portion between the adjacent corresponding grooves 113 and 143.

[0115] Next, in the second contact 300 of this embodiment, an elastic contact portion 320 may be provided at the inner supporting wall portion 140 side end portion of the second central connecting portion 330. The elastic contact portion 320 may be configured as a free end so as to be elastically movable by an external force.

[0116] To this end, the elastic contact portion 320 may include: an elastic arm portion 322 extending from the end of the second central connecting portion 330 toward the positive direction of the Z axis; and a contact arm portion 324 disposed at the end of the elastic arm portion 322 in the extension direction. In addition, the elastic arm portion 322 and the contact arm portion 324 may be disposed in the groove 143 of the inner supporting wall portion 140.

[0117] At this time, in this embodiment, the contact arm portion 324 may have a shape that is bent toward the outer support wall portion 120. Also, in the contact arm portion 324, the thickness t2 of the central portion may be thicker than the thickness t1 of the two side portions in the X-axis direction. In other words, in the contact arm portion 324, the central portion may further protrude in the bending direction.

[0118] Therefore, a relatively stable electrical connection (or energization) state can be achieved and maintained by pressurizing a portion of the other connector that has entered between the inner support wall portion 140 and the outer support wall portion 120 and making contact therewith.

[0119] Next, in this embodiment, a second substrate mounting portion 340 may be connected to the lower end of the second outer contact portion 312 of the second outer coupling portion 310. At this time, the second substrate mounting portion 340 may extend in a direction opposite to the first substrate mounting portion 220. In other words, the second substrate mounting portion 340 may extend toward the outside of the insulating body 100. That is, in this embodiment, the second substrate mounting portion 340 and the aforementioned carrier connecting portion 230 may extend in the same direction.

[0120] As shown in the figure, the second substrate mounting portion 340 may extend along the Y-axis direction. However, there is no particular limitation on the extending direction of the second substrate mounting portion 340 , as long as the end of the second substrate mounting portion 340 faces the direction opposite to the end of the first substrate mounting portion 220 .

[0121] As described above, in the present embodiment, the first substrate mounting portion 220 of the first contact member 200 and the second substrate mounting portion 340 of the second contact member 300 extend in opposite directions to each other, so that the first substrate mounting portion 220 and the second substrate mounting portion 340 are separated to the maximum extent in the Y-axis direction, thereby ensuring insulation performance and preventing a short circuit therebetween.

[0122] In addition, the mounting portions of the first contact 200 and the second contact 300 adjacent to each other are arranged in a zigzag shape. Thus, compared with the connector of the comparative example in which the mounting portions are arranged in parallel in a row, the connector of this embodiment can have a smaller pitch. Here, the pitch can refer to the distance between the connectors adjacent to each other along the X-axis direction.

[0123] For example, the pitch of the connector of the present embodiment can be less than half of the pitch of the connector of the comparative example. Therefore, even if the connector of the present embodiment is mounted on the substrate according to the PCB pattern, short circuits can be prevented from occurring between the PCB pattern bridge or adjacent PCB patterns.

[0124] On the other hand, the second substrate mounting portion 340 can be configured to be mounted on a substrate on which the plug connector 10 is mounted. For example, the second substrate mounting portion 340 can be mounted on the substrate by a welding process, etc. Therefore, a prescribed PCB pattern for combining the second substrate mounting portion 340 and the substrate can be sandwiched between them.

[0125] Figure 4The PCB pattern PS between the plug connector and the substrate is shown. Such PCB pattern PS may be composed of a first PCB pattern PS-1 between the second substrate mounting portion 340 and the substrate, a second PCB pattern PS-2 between the first substrate mounting portion 220 and the substrate, and a third PCB pattern PS-3 between the clamping side substrate mounting portion 450 and the substrate described later.

[0126] At this time, a predetermined gold plating layer L may be provided on the side surface 342 in the extension direction of the second substrate mounting portion 340. Therefore, the side surface 342 may not be exposed to the outside. On the contrary, the extension end surface 344 of the second substrate mounting portion 340 has no gold plating layer L, and may be configured to be exposed to the outside.

[0127] This is because, in the present embodiment, the second substrate mounting portion 340 can perform the function of connecting the carrier and the second contact 300, and in the manufacturing process of the present plug connector 10, the second substrate mounting portion 340 may be cut off in order to separate the second contact 300 and the carrier from each other. Therefore, the end surface 344 of the second substrate mounting portion 340 may be formed as a cut surface without the gold plating layer L.

[0128] Below, refer to Figures 1 to 3 , the relative positional relationship between the first contact 200 and the second contact 300 of the plug connector 10 of this embodiment is described in more detail. In this embodiment, the first contact 200 disposed on any one of the pair of outer support wall portions 120 can be arranged to be aligned with the second contact 300 disposed on the other outer support wall portion 120 in the Y-axis direction.

[0129] In other words, the first contacts 200 disposed at any one of the pair of outer support wall portions 120 may be arranged to be offset from the first contacts 200 disposed at the other outer support wall portion 120 in the Y-axis direction.

[0130] By the above configuration, the first substrate mounting portions 220 of the first contacts 200 arranged on different outer support wall portions 120 are separated from each other in the X-axis direction to the maximum extent, thereby ensuring insulation performance and preventing short circuits therebetween. Thus, a pair of outer support wall portions 120 and the contacts 200 and 300 provided on the pair of outer support wall portions 120 can be closer in the Y-axis direction, so that the plug connector 10 can be constructed more compactly.

[0131] In addition, in this embodiment, the carrier connection portion 230 of the first contact 200 and the second substrate mounting portion 340 of the second contact 300 adjacent to each other along the X-axis direction both extend toward the outside of the insulating body 100, thereby, the first contact 200 and the second contact 300 adjacent to each other along the X-axis direction can be connected together to a carrier.

[0132] Thus, the insert molding process using a pair of carriers provided with the first and second contacts 200 and 300 can be performed to form the insulation body 100 at one time, and thus the plug connector 10 of the present embodiment can be easily and quickly manufactured through a simple process.

[0133] Refer again Figures 1 to 3 In one embodiment of the present invention, the compression retaining wall portion 130 of the plug connector 10 may be combined with a compression structure 400 .

[0134] In this embodiment, the compression structure 400 can guide the combination of another connector combined with the plug connector 10 and perform the function of protecting the compression holding wall portion 130 of the insulating body 100 from external impact or pollution. To this end, the compression structure 400 can be formed of a metal having a specified rigidity.

[0135] In this embodiment, the compression structure 400 may include a top surface protection portion 410 , an inner surface protection portion 420 , an outer surface protection portion 430 , a side protection portion 440 , and a compression-side substrate mounting portion 450 .

[0136] First, the top surface protection part 410 may be provided as a plate-shaped member extending in the X-axis direction and the Y-axis direction and cover the top surface of the compression holding wall part 130. At this time, the top surface protection part 410 may have a sufficient area to cover the entire top surface of the compression holding wall part 130.

[0137] In addition, in this embodiment, one of the two side surfaces of the compression and holding wall portion 130 in the X-axis direction that faces the inner support wall portion 140 may be covered and protected by a plate-shaped inner surface protection portion 420 extending from the top surface protection portion 410 in the negative direction of the Z-axis. In this case, the inner surface protection portion 420 may extend to a length where the end portion in the extension direction is adjacent to the bottom portion 110, so as to be able to protect the entire one side surface.

[0138] Next, in this embodiment, the other side surface of the two side surfaces in the X-axis direction of the compression and holding wall portion 130, which is opposite to the one side surface, can be covered and protected by a plate-shaped outer surface protection portion 430 extending from the top surface protection portion 410 toward the negative direction of the Z-axis. At this time, the outer surface protection portion 430 can fully extend in the Y-axis direction and the Z-axis direction to be able to protect the entire other side surface.

[0139] Next, in this embodiment, the two side surfaces of the compression and holding wall portion 130 in the Y-axis direction can be covered and protected by a pair of side protection portions 440 extending from the top surface protection portion 410 toward the negative direction of the Z-axis and having a plate shape. At this time, the side protection portion 440 can fully extend along the X-axis direction and the Z-axis direction to be able to cover most of the side surfaces.

[0140] In this embodiment, at least one of the inner surface protection portion 420, the outer surface protection portion 430, and the side protection portion 440 may be connected to the aforementioned clamping side substrate mounting portion 450. Such a clamping side substrate mounting portion 450 may be configured to penetrate and pass through the clamping holding wall portion 130. As described above, by a portion of the clamping side substrate mounting portion 450 being mounted on the clamping holding wall portion 130, the clamping structure 400 and the clamping holding wall portion 130 can be strongly combined with each other.

[0141] Furthermore, in this embodiment, at least a portion of the clamping side substrate mounting portion 450 can be exposed toward the lower side direction (negative direction of the Z axis) of the clamping retaining wall portion 130. In addition, the exposed portion can be mounted to the substrate. Thus, the clamping structure 400 can more strongly support the insulating body 100 based on the bonding force with the substrate, and enhance the overall rigidity of the plug connector 10.

[0142] Hereinafter, a connector according to another embodiment of the present invention will be described with reference to different drawings. Figure 8 and Fig. 9 The following are three-dimensional views of a connector according to another embodiment of the present invention viewed from different angles. Fig.10 FIG. 4 is a top view of a connector according to another embodiment of the present invention. Fig.11 is a top view of a PCB pattern formed between a connector and a substrate according to another embodiment of the present invention. Fig.12 is along Fig.10 Cross-sectional view taken along section line Ⅱ-Ⅱ. Fig.13 This is a perspective view of a first contact of a connector according to another embodiment of the present invention as viewed from above. Fig.14 (a) and Fig.14 (b) is a stereoscopic view of a second contact member according to another embodiment of the present invention observed from different angles.

[0143] Reference Figures 7 to 9 , the connector of another embodiment of the present invention may be a socket connector 20. At this time, the socket connector 20 of this embodiment may be configured to match the aforementioned plug connector 10 ( Figure 1 to as shown) and are electrically connected (or energized).

[0144] The socket connector 20 of this embodiment may include an insulating body 500, a first contact 600, a second contact 700, and a pressing structure 800. The insulating body 500 is a structure for providing a base on which other components of the socket connector 20 can be configured. In this case, the insulating body 500 may include a material having a predetermined insulating property to achieve electrical insulation from other components.

[0145] Reference Figures 7 to 10In this embodiment, the insulating body 500 may include a bottom 510 , an outer supporting wall portion 520 , a pressing and holding wall portion 530 , an inner supporting wall portion 540 , and an inner wall portion 550 .

[0146] First, the bottom portion 510 may be provided as a plate-shaped member extending in the X-axis direction and having a predetermined width in the Y-axis direction. The bottom surface of the bottom portion 510 may be placed on one side of the substrate and support the socket connector 20 as a whole.

[0147] At this time, according to this embodiment, a corresponding groove 513 in the form of a cut along the Z-axis direction can be provided. The corresponding groove 513 can be in the same manner as the aforementioned plug connector 10 ( Figure 1 The corresponding groove 113 (shown in Figure 3 ) are constructed with a similar structure to perform the same function.

[0148] Next, an outer supporting wall portion 520 , a pressing and holding wall portion 530 , an inner supporting wall portion 540 , and an inner wall portion 550 may be disposed on the upper side of the bottom portion 510 of the present embodiment.

[0149] At this time, the outer supporting wall portion 520 and the pressing and holding wall portion 530 of this embodiment can be connected with the aforementioned plug connector 10 ( Figure 1 The outer support wall portion 120 (shown in FIG. Figure 1 ) or pressing and holding the wall portion 130 ( Figure 1 ) are similarly constructed to perform the same functions.

[0150] On the other hand, in the present embodiment, a pair of inner support wall portions 540 may be provided between the pair of outer support wall portions 520. The pair of inner support wall portions 540 may be provided as a pair of rod-shaped members extending parallel to each other in the X-axis direction.

[0151] At this time, the pair of inner support wall portions 540 of this embodiment may be separated by a predetermined distance along the Y-axis direction. Thus, a coupling space 511 may be formed between the pair of inner support wall portions 540. In this embodiment, the coupling space 511 may be a structure that allows a part of another connector to enter so that the connector 20 and the other connector can be coupled to each other.

[0152] For example, the aforementioned plug connector 10 ( Figure 1 The inner support wall portion 140 (shown in Figure 1 As shown in FIG. 1 , the connector 20 can be combined with the combination space 511 of the connector 20. The combination between the connectors will be described later. Figures 15 to 18 Let’s explain together.

[0153] At this time, according to the present embodiment, the coupling space 511 may be formed to penetrate the bottom 510 of the insulating body 500. Thus, the first substrate mounting portion 640 of the first contact 600 described later may be observed through the coupling space 511. In other words, the coupling space 511 may function as an inspection window for the first substrate mounting portion 640.

[0154] Such a combined space 511 may extend along the X-axis direction so that the plurality of first substrate mounting portions 640 can be observed. Of course, the combined space 511 may extend along the X-axis direction, and the portion of the combined space 511 that passes through the bottom 510 may also be as shown. Figure 3 The inspection window 111 shown is formed only in a portion of the bottom 510 .

[0155] Hereinafter, of the two side surfaces 542 and 544 of the inner supporting wall portion 540 in the Y-axis direction, the side surface facing the adjacent inner supporting wall portion 540 is defined as a first side surface 542 , and the side surface opposite to the first side surface 542 is defined as a second side surface 544 .

[0156] On the other hand, a groove 545 may be provided on the second side surface 544 of the inner support wall portion 540. At this time, the groove 545 of the inner support wall portion 540 of this embodiment may be aligned with the aforementioned plug connector 10 ( Figure 1 The groove 143 (shown in Figure 3 ) are similarly constructed to perform the same functions.

[0157] In addition, an inner wall portion 550 may be provided on the X-axis side of the pair of inner support wall portions 540. The inner wall portion 550 may increase the overall rigidity of the insulating body 500 by supporting the end of the inner support wall portion 540. Such an inner wall portion 550 may be provided in pair, and each is provided on both sides of the pair of inner support wall portions 540 in the X-axis direction.

[0158] In the present embodiment, the inner wall portion 550 may be provided as a block-shaped member extending in the Y-axis direction to connect the X-axis direction end portions of the pair of inner supporting wall portions 540 to each other.

[0159] Next, refer to Figures 9 to 12 , a first contact 600 and a second contact 700 of a socket connector 20 according to another embodiment of the present invention are described.

[0160] In this embodiment, a plurality of first contacts 600 may be provided and spaced apart along the X-axis direction on the outer support wall 520 and the inner support wall 540. In addition, second contacts 700 may be provided between adjacent first contacts 600 along the X-axis direction.

[0161] At this time, the relative position relationship between the first contact 600 and the second contact 700 of this embodiment can be the same as that of the aforementioned plug connector 10 ( Figure 1 The first contact 200 (shown in FIG. Figure 1 ) and the second contact 300 ( Figure 1 ) are similarly constructed to achieve the same effect.

[0162] Reference Fig.10 and Fig.11 The first contact 600 of the present embodiment may include a first outer combining portion 610 , a first inner combining portion 620 , a first central connecting portion 630 , a first substrate mounting portion 640 , and a carrier connecting portion 650 .

[0163] First, in this embodiment, the first outer combining portion 610 may include a first outer retaining portion 612 , a first outer contact portion 614 and a first outer connecting portion 616 , and is combined with the outer supporting wall portion 540 of the insulating body 500 so that at least a portion is exposed to the outside.

[0164] In this embodiment, the first outer holding portion 612 may extend along the Z-axis direction. Furthermore, the first outer holding portion 612 may be coupled to the second side surface 524 of the outer supporting wall portion 520. At this time, the first outer holding portion 612 may be configured to be partially exposed to the outside, for example, the outer surface of the upper portion is exposed to the outside, but is not limited thereto.

[0165] In addition, the first outer contact portion 614 may extend in the Z-axis direction. At this time, the first outer contact portion 614 may be coupled to the second side surface 524 of the outer supporting wall portion 520 so that a portion of the side surface is exposed to the outside.

[0166] Next, in this embodiment, the first outer connecting portion 616 can connect the upper end of the first outer contact portion 614 and the upper end of the first outer holding portion 612. At this time, the first outer connecting portion 616 can be combined with the top surface of the outer supporting wall portion 520 so that the top surface is exposed upward, but it is not limited thereto.

[0167] On the other hand, the first inner coupling portion 620 of the first contact 600 of this embodiment may include a first inner retaining portion 622 , a first inner contact portion 624 and a first inner connecting portion 626 , and is coupled to the inner supporting wall portion 540 so that at least a portion is exposed to the outside.

[0168] First, in this embodiment, the first inner holding portion 622 may extend along the Z-axis direction and be coupled to the first side surface 542 of the inner supporting wall portion 540. At this time, the first inner holding portion 622 may be configured such that the outer surface is exposed to the outside, but is not limited thereto.

[0169] Also, the first inner contact portion 624 may extend in the Z-axis direction. At this time, the first inner contact portion 624 may be coupled to the second side surface 544 of the inner support wall portion 540 so that a portion of the side surface is exposed to the outside.

[0170] Next, in this embodiment, the first inner connecting portion 626 may connect the upper end of the first inner contact portion 624 and the upper end of the first inner holding portion 622. At this time, the first inner connecting portion 626 may be combined with the top surface of the inner supporting wall portion 540 so that the top surface is exposed upward, but is not limited thereto.

[0171] As described above, the first contact piece 600 of the present embodiment is constructed such that the first outer contact portion 614 and the first inner contact portion 624 are exposed on the side surfaces 522 and 544 of the outer support wall portion 520 and the inner support wall portion 540 that face each other, thereby being able to achieve and maintain double contact with the contact piece of another connector based on the supporting force of the outer support wall portion 520 and the inner support wall portion 540.

[0172] At this time, according to this embodiment, the X-axis direction width w6 of the first inner joint portion 620 may be greater than the X-axis direction width w5 of the first outer joint portion 610. Thus, the first inner joint portion 620 may contact and strongly combine with the inner support wall portion 540 through a wider area, and may be electrically connected (or energized) with a contact of another connector through a wider area.

[0173] Refer again Fig.10 and Fig.11 In this embodiment, a first central connection portion 630 connecting the first outer contact portion 614 of the first outer joint portion 610 and the first inner contact portion 624 of the first inner joint portion 620 may be provided between them. The first central connection portion 630 may extend along the Y-axis direction, and both ends in the extension direction may be connected to the lower end of the first outer contact portion 614 and the lower end of the first inner contact portion 624, respectively.

[0174] In addition, the first central connection part 630 may be combined with the bottom 510 of the insulating body 500. Here, the first central connection part 630 may be configured to have its top surface exposed to the upper side of the bottom 510 and electrically connectable to (or energized by) a contact of another connector, but is not limited thereto.

[0175] On the other hand, in this embodiment, a first substrate mounting portion 640 may be connected to the first inner coupling portion 620. The first substrate mounting portion 640 may be configured to be mounted on a substrate on which the present receptacle connector 20 is placed. To this end, the first substrate mounting portion 640 may extend from the lower end of the first inner retaining portion 622 of the first inner coupling portion 620 to between the pair of inner support wall portions 540.

[0176] As shown in the figure, the first substrate mounting portion 640 can extend along the Y-axis direction, but there is no particular limitation on the extension direction of the first substrate mounting portion 640 as long as the end of the first substrate mounting portion 640 faces between the pair of inner support wall portions 540 .

[0177] At this time, the first substrate mounting portion 640 may extend between a pair of inner supporting wall portions 540 of the insulating body 500. At this time, the first substrate mounting portion 640 may be configured so that at least a portion of the first substrate mounting portion 640 can be observed through the combined space 511. Thus, the mounting state of the first substrate mounting portion 640 can be checked.

[0178] On the other hand, the first outer joint portion 610 may be connected to a carrier connection portion 650. At this time, the carrier connection portion 650 of this embodiment may be connected to the aforementioned plug connector 10 ( Figure 1 The carrier connection portion 230 (shown in FIG. Figure 4 ) are similarly constructed to perform the same functions.

[0179] Reference Fig.10 and Fig.12 The second contact 700 of the present embodiment may include a second outer joint portion 710, an elastic contact portion 720, a second central connection portion 730, and a second substrate mounting portion 740. In addition, the second outer joint portion 710 may include a second outer holding portion 712, a second outer contact portion 714, a second outer connection portion 716, and a contact protrusion portion 718.

[0180] At this time, in this embodiment, the second outer holding portion 712, the second outer contact portion 714, the second outer connecting portion 716, the elastic contact portion 720, the second central connecting portion 730 and the second substrate mounting portion 740 can be connected to the aforementioned plug connector 10 ( Figure 1 The second outer contact portion 312 (shown in Figure 4 ), the second inner contact portion 314 ( Figure 4 ), the second outer connecting portion 316 ( Figure 4 ), the elastic contact portion 320 ( Figure 4 ), the second central connecting portion 330 ( Figure 4 ) and the second substrate mounting portion 340 ( Figure 4 ) are similarly constructed to perform the same functions.

[0181] At this time, according to this embodiment, the width w7 of the second outer joint portion 710 in the X-axis direction may be greater than the width w8 of the elastic contact portion 720 in the X-axis direction. Thus, the second outer joint portion 710 may contact and strongly combine with the outer supporting wall portion 520 through a wider area, and may be electrically connected (or energized) with a contact of another connector through a wider area.

[0182] Refer again Fig. 9 , if the positional relationship between the first contact 600 and the second contact 700 is considered, the first outer joint portion 610 having a relatively narrow width w5 is arranged between the second outer joint portions 710 having a relatively wide width w7 on the outer supporting wall portion 520 along the X-axis direction. In addition, the first inner joint portion 620 having a relatively wide width w6 is arranged between the elastic contact portions 720 having a relatively narrow width w8 on the inner supporting wall portion 540 along the X-axis direction.

[0183] As described above, in the connector of this embodiment, the first contacts 600 and the second contacts 700 having different widths are alternately arranged, and the distance between the contacts is constant, so that the connector as a whole can have uniform strength and the strength of the connector can be improved.

[0184] Furthermore, in this embodiment, the first inner coupling portion 620 of the first contact 600 is disposed between the corresponding grooves 513 and 545 adjacent to each other along the X-axis direction. The first inner coupling portion 620 can enhance the strength of the portion between the adjacent corresponding grooves 513 and 545.

[0185] In addition, if the positional relationship between the aforementioned first contact member 600 and the second contact member 700 is considered together, in the outer support wall portion 520 of the present embodiment, the first outer coupling portion 610 having a relatively narrow width w5 is arranged along the X-axis direction between the second outer coupling portion 710 having a relatively wide width w7, and in the inner support wall portion 540, the first inner coupling portion 620 having a relatively wide width w6 is arranged along the X-axis direction between the elastic contact portions 720 having a relatively narrow width w8, so that the first contact member 600 and the second contact member 700 can be combined with the outer support wall portion 520 and the inner support wall portion 540 at a higher density.

[0186] On the other hand, the contact protrusion 718 of the present embodiment can protrude from the side of the second outer contact portion 714 toward between the outer support wall portion 520 and the inner support wall portion 540. Such a contact protrusion 718 is configured to enable another connector that enters between the outer support wall portion 520 and the inner support wall portion 540 to be stuck and fixed, thereby enabling stable connection (or contact) of the two connectors. At this time, the contact protrusion 718 can be located adjacent to the second outer connection portion 716.

[0187] In this embodiment, the contact protrusion portion 718 may include: a first protruding surface 718a, the height of which is spaced apart from the second outer contact portion 714 increases as it goes toward the negative direction of the Z axis; and a second protruding surface 718b, the height of which is spaced apart from the second outer contact portion 714 decreases as it goes toward the negative direction of the Z axis. At this time, the second protruding surface 718b is more inclined than the first protruding surface 718a relative to the second outer contact portion 714, thereby being able to effectively perform the aforementioned snap-fit ​​function.

[0188] on the other hand, Fig.11 The PCB pattern RS between the socket connector and the substrate is shown. This PCB pattern RS can be composed of a first PCB pattern RS-1 between the second substrate mounting portion 740 and the substrate, a second PCB pattern RS-2 between the first substrate mounting portion 640 and the substrate, and a third PCB pattern RS-3 between the clamping side substrate mounting portion 890 and the substrate described later.

[0189] Refer again Figures 7 to 9 In the present embodiment, the insulating body 500 of the socket connector 20 may be combined with a compression structure 800. A pair of compression structures 800 may be provided, and each is combined with two sides of the insulating body 500 in the X-axis direction.

[0190] In this embodiment, the clamping structure 800 may include an outer wall top surface protection portion 810, an outer wall inner surface protection portion 820, a central bottom protection portion 830, an inner wall outer surface protection portion 840, an outer support wall top surface protection portion 850, an outer support wall inner surface protection portion 860, a side bottom protection portion 870, a snap-fit ​​protrusion 880 and a clamping side substrate mounting portion 890.

[0191] In this embodiment, the outer wall top surface protection portion 810 can be provided as a plate-shaped component that covers and protects the top surface of the compression and holding wall portion 530 facing the positive direction of the Z axis; the outer wall inner surface protection portion 820 can be provided as a plate-shaped component that covers and protects the side surface of the compression and holding wall portion 530 facing the inner supporting wall portion 540; the inner wall outer surface protection portion 840 can be provided as a plate-shaped component that covers and protects the side surface of the inner wall portion 550 facing the outer side of the first inner space S1; the outer support wall top surface protection portion 850 can be provided as a plate-shaped component that covers and protects the top surface of the outer support wall portion 520 facing the positive direction of the Z axis; the outer support wall inner surface protection portion 860 can be provided as a plate-shaped component that covers and protects the side surface of the outer support wall portion 520 facing the inner support wall portion 540.

[0192] At this time, the outer wall top surface protection portion 810, the outer wall inner surface protection portion 820, the inner wall outer surface protection portion 840, the outer support wall top surface protection portion 850, and the outer support wall inner surface protection portion 860 can each extend in a specified direction to cover the entire protected surface, and a part can include a curved surface as needed.

[0193] Reference Fig. 9 In this embodiment, the top surface of the bottom 510 arranged between the clamping and retaining wall portion 530 and the inner wall portion 550 can be covered and protected by a central bottom protection portion 830 and a pair of side bottom protection portions 870 symmetrically arranged on both sides of the central bottom protection portion 830 in the Y-axis direction.

[0194] At this time, the central bottom protecting portion 830 and the side bottom protecting portion 870 may be provided as plate-shaped members to be able to cover the central portion of the top surface of the bottom 510 and both side portions of the central portion when viewed in the Y-axis direction.

[0195] At this time, in this embodiment, a locking protrusion 880 protruding toward the positive direction of the Z axis may be provided on the Y-axis side of the side bottom protection portion 870. At this time, the locking protrusion 880 may be configured to elastically move (or shift) in the Y-axis direction.

[0196] The engaging protrusion 880 can be fixed in position by elastically supporting a part of another connector that enters between the compression holding wall portion 530 and the inner wall portion 550. At this time, in order to ensure smooth movement of the engaging protrusion 880, a predetermined groove or hole for providing a space for the engaging protrusion 880 to move (or move) can be formed on the side surface of the outer supporting wall portion 520 and the outer supporting wall inner surface protection portion 860.

[0197] Refer again Figure 8The clamping side substrate mounting portion 890 of the clamping structure 800 of the present embodiment may be configured to have a structure and function similar to the clamping side substrate mounting portion 450 of the clamping structure 400 of the aforementioned plug connector 10 .

[0198] Hereinafter, a connector assembly according to an embodiment of the present invention will be described with reference to other drawings. Fig.15 It is an exploded perspective view of a connector assembly according to an embodiment of the present invention. Fig.16 This is a perspective view of a connector assembly according to an embodiment of the present invention as viewed from above. Fig.17 is along Fig.16 Cross-sectional view taken along section line III-III. Fig.18 is along Fig.16 Cross-sectional view taken along section line IV-IV.

[0199] Reference Fig.13 and Fig.14 The connector assembly 1 of one embodiment of the present invention can be formed by combining two connectors in a shape-matching manner. At this time, in this embodiment, the two connectors can be a plug connector 10 of one embodiment of the present invention and a socket connector 20 of another embodiment of the present invention, but are not limited thereto.

[0200] In this embodiment, the inner support wall portion 140 of the plug connector 10 can enter the coupling space 511 provided between the pair of inner support wall portions 540 of the socket connector 20. The outer support wall portion 120 of the plug connector 10 can enter the specified space S provided between the outer support wall portion 520 and the inner support wall portion 540 of the socket connector 20.

[0201] In addition, the compression retaining wall portion 130 of the plug connector 10 can enter between the inner wall portion 550 and the compression retaining wall portion 530 of the receptacle connector 20. In the above process, the compression structure 400, 800 can perform the functions of protecting the compression retaining wall portion 130, 530 and the bottom portion 110, 510, and guiding the combination of the two connectors 10, 20.

[0202] As described above, in the connector assembly 1 of the present embodiment, the plug connector 10 has an inner support wall portion 140, and the inner support wall portion 140 is combined with the coupling space 511 of the socket connector 20 in a shape-matched manner, thereby increasing the coupling force between the two connectors 10 and 20 and strengthening the overall rigidity of the connector assembly 1.

[0203] Reference Fig.15 As shown in the figure, the second outer contact portion 312 of the second contact 300 of the plug connector 10 can be electrically connected (or energized) to the first outer contact portion 614 of the first contact 600 of the socket connector 20 .

[0204] Furthermore, the second inner contact portion 314 of the second contact 300 of the plug connector 10 may be electrically connected (or energized) to the first inner contact portion 624 of the first contact 600 of the socket connector 20 .

[0205] Furthermore, the elastic contact portion 320 of the second contact piece 300 of the plug connector 10 can elastically move as it is pressurized by the inner support wall portion 540 of the socket connector 20 that enters between the outer support wall portion 120 and the inner support wall portion 140, and is electrically connected (or energized) to the first inner retaining portion 622 of the first contact piece 600 of the socket connector 20.

[0206] As described above, the plug connector 10 and the receptacle connector 20 of the present embodiment can contact each other at a plurality of locations and stably maintain electrical connection (or contact).

[0207] Likewise, the second outer contact portion 714 of the second contact 700 of the socket connector 20 may be electrically connected (or electrically connected) to the first outer contact portion 212 of the first contact 200 of the plug connector 10 .

[0208] Furthermore, the elastic contact portion 720 of the second contact piece 700 of the socket connector 20 can elastically move as it is pressurized by the outer support wall portion 120 of the plug connector 10 that enters between the outer support wall portion 520 and the inner support wall portion 540, and is electrically connected (or in contact) with the first inner contact portion 214 of the first contact piece 200 of the plug connector 10.

[0209] In particular, a more stable connection (or contact) can be achieved by engaging and fixing the outer support wall portion 120 of the plug connector 10 and the first outer coupling portion 210 coupled thereto between the contact protrusion 718 and the elastic contact portion 720 of the second contact piece 700 of the socket connector 20.

[0210] On the other hand, refer to Fig.16 As described above, the compression retaining wall portion 130 of the plug connector 10 may be coupled between the compression retaining wall portion 530 and the inner side wall portion 550 of the socket connector 20 in a shape-matched manner.

[0211] More specifically, in this embodiment, the extension direction end surface 144 of the inner support wall portion 140 of the plug connector 10 and the side surface 552 in the X-axis direction of the inner wall portion 550 of the socket connector 20 may face each other.

[0212] Furthermore, it may be configured that the outer surface 842 of the inner side wall outer surface protection portion 840 of the receptacle connector 20 and the outer surface 422 of the inner surface protection portion 420 of the plug connector 10 in the X-axis direction face each other.

[0213] At this time, the outer surface 842 of the inner wall outer surface protection portion 840 may refer to the surface facing the negative direction of the X-axis to protect the other side surface of the inner wall portion 550 of the socket connector 20 in the X-axis direction, and the outer surface 422 of the inner surface protection portion 420 may refer to the surface facing the positive direction of the X-axis to protect the side surface of the clamping and retaining wall portion 130 of the plug connector 10 in the X-axis direction.

[0214] Furthermore, it may be configured that the outer surface 822 of the outer side wall inner surface protection portion 820 of the receptacle connector 20 and the outer surface 432 of the outer surface protection portion 430 of the plug connector 10 in the X-axis direction face each other.

[0215] At this time, the outer surface 822 of the inner surface protection portion 820 of the outer wall may refer to the surface facing the positive direction of the X-axis to protect the side surface of the clamping and retaining wall portion 530 of the socket connector 20 in the X-axis direction, and the outer surface 432 of the outer surface protection portion 430 may refer to the surface facing the negative direction of the X-axis to protect the other side surface of the clamping and retaining wall portion 130 of the plug connector 10 in the X-axis direction.

[0216] On the other hand, in the present embodiment, the X-axis direction distance d1 (hereinafter referred to as the first distance) between the extension direction end surface 144 of the inner support wall portion 140 of the plug connector 10 and the one side surface 552 of the inner wall portion 550 of the socket connector 20 can be set to be greater than the X-axis direction distance d2 (hereinafter referred to as the second distance) between the outer surface 842 of the inner wall outer surface protection portion 840 of the socket connector 20 and the outer surface 422 of the inner surface protection portion 420 of the plug connector 10.

[0217] In addition, in this embodiment, the second distance d2 can be greater than the X-axis direction distance d3 (hereinafter referred to as the third distance) between the outer surface 822 of the inner surface protection portion 820 of the outer wall of the socket connector 20 and the outer surface 432 of the outer surface protection portion 430 of the plug connector 10.

[0218] In other words, the first to third distances (d1 to d3) may satisfy Math Formula 1 below.

[0219] [Mathematical formula 1]

[0220] first distance d1>second distance d2>third distance d3

[0221] This distance (or tolerance) is intended to guide the shape-matching combination of the plug connector 10 and the socket connector 20 through the interaction between the clamping structure 400 of the plug connector 10 and the clamping structure 800 of the socket connector 20, and to prevent the inner support wall portion 140 of the plug connector 10 and the inner wall portion 550 of the socket connector 20 from interfering with and being damaged by each other.

[0222] This is because if the first distance d1 is shorter than the second distance d2 or the third distance d3, the inner support wall portion 140 of the plug connector 10 and the inner wall portion 550 of the receptacle connector 20 are more likely to interfere with each other and be damaged during the coupling of the two connectors 10, 20.

[0223] Furthermore, one purpose of the connector assembly 1 is to achieve an ultra-narrow pitch. To this end, the gap in the length direction (X-axis direction in the drawing) of the connector after the plug connector 10 and the socket connector 20 are combined must be small, and damage must be prevented during the combination of the two connectors 10 and 20.

[0224] To this end, in this embodiment, according to Mathematical Formula 1, the gap between the outer wall inner surface protection portion 820 of the socket connector 20 having relatively strong strength and the outer surface protection portion 430 of the plug connector 10 (i.e., the third distance d3) can be set to the minimum, and the gap between the inner wall portion 550 of the socket connector 20 having relatively weak strength and the inner support wall portion 140 of the plug connector 10 (i.e., the first distance d1) can be set to the maximum. Thus, damage caused by interference between fragile portions can be prevented.

[0225] Although the embodiments of the present invention have been described, the concept of the present invention is not limited to the embodiments given in this specification. Those skilled in the art who understand the concept of the present invention can easily propose other embodiments within the scope of the same concept by adding, changing, deleting, and appending constituent elements, which also falls within the scope of the concept of the present invention.
