Description

Technical Field

[0001] This invention relates to a connector assembly and a connector housing. Background Technology

[0002] Today, with the increasing performance requirements of servers in data processing and computing systems, the stability and ease of use of connectors have become crucial. A busbar connector is a connection component used to connect a busbar to other electronic devices or systems. It is used for high-power transmission, ensuring a stable and reliable power connection, and is commonly found in server racks and power distribution systems. The primary function of a busbar connector is to reliably connect these buses to the power input terminals of devices (such as power supplies, servers, etc.).

[0003] Electronic equipment racks, such as those housing servers, primarily support the equipment and provide power connections. When electronic devices in these racks operate under high processing loads or high power consumption, they may draw significant power from connectors. If the connector plugs and sockets do not connect properly, it can lead to potential problems with inefficient power delivery. Therefore, a high-performance connector assembly is needed to address these potential issues. Summary of the Invention

[0160] The following description provides numerous different embodiments or examples for implementing various features of the provided objective. Specific examples of components and configurations are described below to simplify the content of the invention. Of course, these are merely examples and are not intended to be limiting. For instance, in the following description, the formation of a first feature over or on a second feature may include embodiments where the first and second features are formed in direct contact, and may also include embodiments where additional features may be formed between the first and second features such that the first and second features are not in direct contact. Furthermore, in various instances, the content of the invention may repeatedly refer to numbers and / or letters. This repetition is for simplicity and clarity and does not, in itself, define the relationship between the various embodiments and / or configurations discussed.

[0161] Additionally, for ease of description, spatial relative terms such as "beneath," "below," "lower," "above," and "upper," and similar terms, may be used herein to describe the relationship between one component or feature as illustrated in the figures and another component or feature. Besides the orientations depicted in the figures, these spatial relative terms are intended to also cover different orientations of components in use or operation. Devices may be oriented in other ways (rotated 90 degrees or otherwise), and the spatial relative descriptors used herein may be interpreted accordingly.

[0162] Figure 1 This is a perspective view of the connector assembly in the embodiment. The icon represents a bus connector assembly, also known as connector assembly M1. Connector assembly M1 is a connection component that connects a busbar to other electronic devices or systems. It is mainly used for high-power transmission, ensuring a stable and reliable power connection, and is commonly found in server racks and power distribution systems. Figures 1 to 11C The detailed structure of connector assembly M1 will be discussed.

[0163] exist Figure 1 In one embodiment, the connector assembly M1 includes a connector 1, a plurality of conductive strip groups 60, a plurality of sockets 200, and a plurality of plugs 100.

[0164] For example, connector assembly M1 has two conductive strip groups 60, which are electrically connected to connector 1 and extend to both sides of connector 1 respectively. On the other hand, connector assembly M1 also has two sockets 200 and two plugs 100, wherein each socket 200 is electrically connected to a corresponding conductive strip group 60, and each plug 100 is connected to or coupled to a corresponding socket 200.

[0165] In some embodiments, the two conductive strip groups 60 may be cable groups, electrical connection sockets 200, and connectors 1.

[0166] In some embodiments, connector 1 may also be referred to as a Bus Bar Clip Connector (BBC Connector). Specifically, connector 1 has a housing 11, the front of which defines two slots 10. In some embodiments, the slots 10 are flat elongated slots with openings on three adjacent sides. Connector 1 also has a plurality of conductive terminal structures 12 inserted into the housing 11.

[0167] Connector 1 can be used to connect to an external bus system (e.g., a server bus). For example, the external bus system may have two external terminals that insert into slots 10 of housing 11 and are electrically connected to corresponding conductive terminal structures 12. The two external terminals of the external bus system may provide different potentials. For example, these two different potentials may be a positive voltage and a ground voltage, respectively.

[0168] On the other hand, each conductive strip group 60 has a first conductive strip 60A and a second conductive strip 60B. The first conductive strip 60A and the second conductive strip 60B each have a fixing portion (or a first connecting portion), a connecting portion (or a second connecting portion), and an extension portion (or a main body portion) located between the fixing portion and the connecting portion. The fixing portion of the first conductive strip 60A is electrically connected to one of the conductive terminal structures 12 of the connector 1, while the fixing portion of the second conductive strip 60B is electrically connected to the other conductive terminal structure 12 of the connector 1. That is, the first conductive strip 60A and the second conductive strip 60B can each receive different potentials provided by an external bus system. For example, the first conductive strip 60A can be a positive busbar, connected to the positive voltage of the power supply, and transmits current to the load on the circuit board 400, while the second conductive strip 60B can be a negative busbar, connected to the ground voltage of the power supply, and transmits the returning current back to the power supply.

[0169] Furthermore, the first conductive strip 60A and the second conductive strip 60B of each conductive strip group 60 are electrically insulated from each other. In some embodiments, the first conductive strip 60A and the second conductive strip 60B may be covered with an insulating film or insulating element to prevent short circuits caused by contact between the first conductive strip 60A and the second conductive strip 60B. In other embodiments, the first conductive strip 60A and the second conductive strip 60B may be made of rigid materials, such as brass, and there may be sufficient gaps between the first conductive strip 60A and the second conductive strip 60B to prevent contact between them.

[0170] In each group of conductive strips 60, the extensions of the first conductive strip 60A and the second conductive strip 60B extend from the connector 1 and are arranged side by side. Then, the connecting parts are connected to different socket terminals in the socket 200. This side-by-side arrangement of the extensions minimizes the space required for the first conductive strip 60A and the adjacent second conductive strip 60B outside the connector 1 and the socket 200.

[0171] In addition, Figure 1In some embodiments, the plug 100 is mounted on the circuit board 400 and mates with the corresponding socket 200. In some embodiments, the circuit board 400 is a server motherboard. The different potentials provided by the two external terminals of the external bus system can be transmitted to the corresponding circuit board 400 via the connector 1, and through the corresponding conductive strip group 60, socket 200, and plug 100. It should be understood that although... Figure 1 The icon shows two circuit boards 400, but in other embodiments, these circuit boards 400 may be different portions of a single circuit board. In some embodiments, circuit board 400 may also be a conductive strip or a printed circuit board (PCB) configured in connection with connector 100 and providing current conduction.

[0172] exist Figure 1 In some embodiments, the plug 100 is mated or coupled to a corresponding socket 200, and a connecting panel 300 is provided between the plug 100 and the socket 200. The socket 200 can be mounted on the connecting panel 300, and the plug 100 is inserted into the corresponding socket 200 through holes in the connecting panel 300. In some embodiments, the connecting panel 300 can be part of the server housing. It should be understood that although... Figure 1 Two connection panels 300 are shown; however, in other embodiments, these connection panels 300 may be different portions of a single connection panel.

[0173] Figure 2A This is a perspective view of the conductive terminal structure in the embodiment. Figure 2B This is a side view of the conductive terminal structure, which will be discussed. Figure 1 Detailed structure of conductive terminal structure 12 inside housing 11 of connector 1.

[0174] Each of the conductive terminal structures 12 has a conductive block 1200 and a pair of spring contacts 1210 connected to the conductive block 1200. The spring contacts 1210 are arranged opposite to each other and gradually approach each other in the direction away from the conductive block 1200, together forming a socket with compressive elasticity. Please refer to [reference needed]. Figure 1 When the conductive terminal structure 12 is installed in the housing 11 of the connector 1, the socket formed by each pair of spring contacts 1210 can correspond to the slot 10 of the housing 11 of the connector 1.

[0175] When an external terminal passes through the slot 10 of the housing 11 and is inserted into the socket formed by the spring 1210, the pressing force generated by the spring 1210 can make the spring 1210 contact and press the external terminal, so as to maintain the positive force of the spring 1210 on the external terminal within a predetermined range, such as 100 to 200 gf (gram-force), so as to appropriately reduce the contact resistance between the external terminal and the spring 1210, while avoiding excessive friction and wear on the surface due to excessive positive force.

[0176] In some embodiments, the conductive block 1200 may have multiple holes 1202, while the spring piece 1210 has multiple holes 1212, wherein the holes 1212 of the spring piece 1210 may correspond to some of the holes 1202 of the conductive block 1200. This allows fastening components (such as rivets or screws) to pass through the holes 1212 of the spring piece 1210 and the holes 1202 of the conductive block 1200, thus securing the spring piece 1210 to the conductive block 1200 together. In some embodiments, the front end of the conductive block 1200 for securing the spring piece 1210 has a mounting groove, so that the surface of the spring piece 1210 after being secured is flush with the rear end surface of the conductive block 1200. In some embodiments, other holes 1202 of the conductive block 1200 do not correspond to the holes 1212 of the spring piece 1210; these holes 1202 can be used to secure other components to the conductive block 1200.

[0177] In some embodiments, the conductive block 1200 further has a groove 1204, wherein the groove 1204 can be used to couple with the protrusion 1110 of the housing 11 of the connector 1. In some embodiments, each spring 1210 has a protruding structure 1214 at opposite ends of its rear end, wherein the protruding structure 1214 can be used to be embedded into a corresponding groove on the inner surface of the housing 11 of the connector 1.

[0178] In some embodiments, the leading edge of the spring 1210 has a plurality of contact terminals 1215, wherein the contact terminals 1215 are arranged in a vertical direction and spaced apart from each other by gaps 1216. Furthermore, please refer to... Figure 2B The width of each contact terminal 1215 is greater than the width of each gap 1216, preferably in a ratio of 2:1 or higher, to ensure that the conductive terminal structure 12 and the external terminals have sufficient contact area to support larger currents.

[0179] Figure 3A and Figure 3B This is a perspective view of the conductive terminal structure and conductive strip assembly of an embodiment, which will be discussed. Figure 1 The connection relationship between the conductive terminal structure 12 of connector 1 and the conductive strip assembly 60. For ease of viewing, Figure 3A Only the second conductive strip 60B in the conductive strip group 60 is shown.

[0180] Please refer to this first. Figure 3A In some embodiments, two second conductive strips 60B can be first fixed to one of the conductive terminal structures 12. In some embodiments, one end (fixing portion) of each of the two second conductive strips 60B also has a hole. Then, the two second conductive strips 60B and their corresponding conductive terminal structures 12 can be fixed together by a fixing component 1220 passing through the holes of the two second conductive strips 60B and the hole of the conductive block 1200. In some embodiments, part of the fixing portion is on the outer surface of the spring piece 1210, that is, part of the hole of the fixing portion aligns with the hole 1212 of the spring piece 1210, so that the spring piece 1210 is clamped between the second conductive strip 60B and the conductive block 1200. The two second conductive strips 60B and the conductive terminal structure 12 are electrically connected to each other through contact. In some embodiments, the fixing component 1220 can be a rivet, a screw, or other suitable fixing component. In some embodiments, the fixing portions of the two second conductive strips 60B overlap and are fixed to the outer surface (the side away from the other conductive terminal structure 12) of the conductive terminal structure 12. The extension portions of the two second conductive strips 60B extend to the left and right sides respectively from the same side (e.g., the upper side) of the conductive block 1200. The fixing portion and the extension portion have an included angle with each other, preferably perpendicular to each other. In some embodiments, the extension portions of the two second conductive strips 60B may extend to the left and right sides respectively from different sides (e.g., the upper and lower sides) of the conductive block 1200.

[0181] Next, please refer to Figure 3B After fixing two second conductive strips 60B to one of the conductive terminal structures 12, two first conductive strips 60A can be fixed to the other conductive terminal structure 12. In some embodiments, the fixing portions of the two first conductive strips 60A overlap and are fixed to the outside of the other conductive terminal structure 12. The connection relationship between the first conductive strip 60A and its corresponding conductive terminal structure 12 is basically the same as the connection relationship between the second conductive strip 60B and its corresponding conductive terminal structure 12, so it will not be described again. In other embodiments, the two first conductive strips 60A can be fixed to one conductive terminal structure 12 first, and then the two second conductive strips 60B can be fixed to the other conductive terminal structure 12. The extension portions of the two second conductive strips 60B fixed to the conductive block 1200 extend to the left and right sides from the same side, and the extension portions of the two first conductive strips 60A fixed to the other conductive block 1200 extend to the left and right sides from different sides. This design allows each conductive block 1200 to have an extension of a conductive strip passing adjacent to its upper and lower sides, thus forming a symmetrical layout.

[0182] In some embodiments, the ends of the first conductive strip 60A and the second conductive strip 60B furthest from the conductive terminal structure 12 each have a connecting portion 602, and each connecting portion 602 has a hole 600. In some embodiments, the connecting portion 602 is a plate-like structure with an angle between it and the extension, preferably the connecting portion 602 and the extension are perpendicular to each other. In some embodiments, the connecting portions 602 of the first conductive strip 60A and the second conductive strip 60B are aligned horizontally with each other. On the other hand, each of the conductive strip groups 60 can be bent to form a receiving space 610 on one side of the conductive terminal structure 12. In some embodiments, the receiving space 610 has a "U-shaped" cross-sectional profile. This receiving space 610 helps to fix the housing 11 of the connector 1 to the external components.

[0183] Figure 4 This is a perspective view of the connector housing in an embodiment, which will be discussed. Figure 1 Detailed structure of the housing 11 of connector 1.

[0184] The housing 11 has wings 13 extending to opposite sides of the housing 11. In some embodiments, each wing 13 has at least one hole 1130. The housing 11 can be secured to an outer housing, such as a server housing, via the wings 13. For example, the surface of the wing 13 facing the slot 10 can be abutted against an outer housing, aligning the hole 1130 of the wing 13 with a hole in the outer housing. Then, the wings 13 of the housing 11 are secured to the outer housing by fastening components, such as screws or rivets, passing through the hole 1130 of the wing 13 and the hole in the outer housing. Also see... Figure 1 as well as Figure 3B The holes 1130 of the wing 13 will correspond to the receiving space 610 formed by the conductive strip group 60. In this way, the wing 13 of the housing 11 can be locked to the outer housing by the fixing components through the receiving space 610 without being obstructed.

[0185] The housing 11 also has a protruding structure 1100 and two protrusions 1110, located on opposite sides of the protruding structure 1100. In some embodiments, the protruding structure 1100 extends a greater distance than the protrusions 1110. In some embodiments, the protruding structure 1100 also has a plurality of spring tabs 1102, wherein the spring tabs 1102 are respectively disposed on two opposite surfaces of the protruding structure 1100. In some embodiments, two spring tabs 1102 are respectively disposed on one side of the protruding structure 1100. In some embodiments, the spring tabs 1102 may be metal sheets and may be fixed to the protruding structure 1100 at their rear ends by fastening components, such as rivets or screws, while the front ends are free ends and offset outward in a direction away from the protruding structure 1100. On the other hand, the protrusions 1110 have grooves 1112. In some embodiments, each protrusion 1110 has a plurality of grooves 1112. In addition, a plurality of grooves 1120 are also provided in the upper inner surface and the lower inner surface of the housing 11.

[0186] Figure 5A This is a perspective view of the conductive terminal structure and housing in an embodiment. Figure 5B This is a cross-sectional view of the conductive terminal structure and housing, which will be discussed. Figure 1 The connection relationship between the conductive terminal structure 12 of connector 1 and the housing 11.

[0187] In some embodiments, it can be as follows: Figure 3A and Figure 3B The discussed procedure involves first attaching the conductive strip assembly 60A to the conductive terminal structure 12, and then inserting the conductive terminal structure 12 into the housing 11. However, for ease of viewing, Figure 5A and Figure 5B The conductive strip group 60 was not drawn.

[0188] First, the two conductive terminal structures 12 are inserted into the housing 11 along opposite sides of the protruding structure 1100. This positions the protruding structure 1100 between the two conductive terminal structures 12, thus electrically isolating them from each other. The contact terminals 1215 of the spring tabs 1210 of the conductive terminal structures 12 extend to the slots 10 of the housing 11.

[0189] Furthermore, the protruding structure 1214 of the spring tab 1210 of the conductive terminal structure 12 will be embedded into the groove 1120 of the housing 11. This design can restrict the movement of the conductive terminal structure 12 in the plane perpendicular to the slot 10, so as to fix the conductive terminal structure 12 to the housing 11.

[0190] On the other hand, the protrusion 1110 of the housing 11 will be embedded into the groove 1204 of the conductive block 1200 of the conductive terminal structure 12. Additionally, in Figure 5BIn the cross-sectional view, a portion of the fixing component 1220 passing through the conductive terminal structure 12 is exposed in the groove 1204 of the conductive block 1200, and this portion of the fixing component 1220 is embedded in the groove 1112 of the protrusion 1110. Similarly, this design can also restrict the movement of the conductive terminal structure 12 in the plane perpendicular to the slot 10 and forward (towards the slot 10) to fix the conductive terminal structure 12 to the housing 11.

[0191] Please refer to Figure 5B When the conductive terminal structure 12 is inserted into the housing 11, the fixing component 1220 on the conductive terminal structure 12 will press the front end (free end) of the spring piece 1102 on the protruding structure 1100 of the housing 11 inward until the fixing component 1220 passes through the spring piece 1102. Then, the spring piece 1102 will rebound and abut against the fixing component 1220 and the spring piece 1210 of the conductive terminal structure 12. This design ensures that the conductive terminal structure 12 will not fall out after being inserted into the housing 11.

[0192] Figure 6A The image shows a perspective view of the conductive strip assembly and socket in an embodiment. Figure 6B Its cross-sectional view will be discussed. Figure 1 The connection relationship between the conductive strip group 60 and the socket 200.

[0193] In some embodiments, the socket 200 has a socket housing 210 and a plurality of socket connectors 220 (or socket terminals). In some embodiments, each socket 200 has two socket connectors 220. Initially, the two socket connectors 220 may be mounted on the first conductive strip 60A and the second conductive strip 60B of the conductive strip assembly 60, respectively. In some embodiments, the socket connectors 220 may comprise copper, a copper alloy, or a similar conductive material.

[0194] Please refer to this first. Figure 6BEach socket connector 220 has a main body portion 2200, an insert portion 2202 connecting the main body portion 2200, and a locking portion 2204 connecting the insert portion 2202. In some embodiments, the main body portion 2200, the insert portion 2202, and the locking portion 2204 are generally cylindrical, with the diameter of the main body portion 2200 being larger than the diameter of the insert portion 2202, and the diameter of the insert portion 2202 being larger than the diameter of the locking portion 2204. During installation, the insert portion 2202 of the socket connector 220 can be inserted into the hole 600 of the connection portion 602 of the first conductive strip 60A (or the second conductive strip 60B). In some embodiments, the diameter of the insert portion 2202 of the socket connector 220 is slightly larger than the diameter of the hole 600, which ensures that the insert portion 2202 can be securely engaged in the hole 600 of the connection portion 602 of the first conductive strip 60A (or the second conductive strip 60B). Furthermore, the surface of the embedded portion 2202 may have serrations, which will help to snap the embedded portion 2202 into the hole 600. In some embodiments, the main portion 2200 and the embedded portion 2202 may be cuboid or other polyhedral structures.

[0195] Thus, the main body portion 2200 with a larger diameter will abut against one side of the first conductive strip 60A (or the second conductive strip 60B), while the locking portion 2204 will protrude from the other side of the first conductive strip 60A (or the second conductive strip 60B). In some embodiments, the surface of the locking portion 2204 has threads. Therefore, the socket connector 220 can be locked onto the corresponding first conductive strip 60A or second conductive strip 60B and electrically connected thereto by screwing in a fastening component 2206, such as a nut, into the locking portion 2204.

[0196] Furthermore, the main body portion 2200 of the socket connector 220 has a first portion 2200A, a second portion 2200B, and a third portion 2200C, wherein the second portion 2200B is located between the first portion 2200A and the third portion 2200C. In some embodiments, the width (diameter) of the second portion 2200B is greater than the width (diameter) of the first portion 2200A and the third portion 2200C.

[0197] On the other hand, the socket connector 220 also has a slot 2208 located within the main body portion 2200. The slot 2208 is for mating conductive terminals of a plug. A conductive annular elastic component (e.g., a crown spring) can be installed within the slot 2208 to strengthen the electrical connection between the socket connector 220 and the conductive terminal. Furthermore, the socket connector 220 also has an air hole 2210 that penetrates the main body portion 2200, the insert portion 2202, and the locking portion 2204, and connects to the slot 2208. Thus, when a conductive terminal is inserted into the slot 2208 of the socket connector 220, air inside the slot 2208 can be expelled through the air hole 2210, facilitating the insertion of external terminals into the socket connector 220. Additionally, the air hole 2210 can also serve as a flow channel for the electroplating solution during electroplating of the socket connector 220.

[0198] Please refer to the reply. Figure 6A The socket housing 210 includes an upper housing 211 and a lower housing 212. In some embodiments, the upper housing 211 and the lower housing 212 are assembled to form an alignment groove 213 corresponding to the shape of the socket connector 220, positioning the socket connector 220 within the socket housing 210. Specifically, each of the upper housing 211 and the lower housing 212 has two alignment grooves 213, each having a generally semi-circular outline. When the upper housing 211 and the lower housing 212 are joined, the alignment groove 213 of the upper housing 211 and its corresponding alignment groove 213 of the lower housing 212 merge to form a circular receiving groove, in which the socket connector 220, having a cylindrical structure, can be positioned. The receiving groove is formed corresponding to the outline of the main body portion 2200 of the socket connector 220; in some embodiments, it can be a rectangular groove or a multi-faceted groove.

[0199] More specifically, the alignment groove 213 may have a first portion 213A, a second portion 213B, and a third portion 213C, wherein the second portion 213B is located between the first portion 213A and the third portion 213C. In some embodiments, the diameter of the second portion 213B is larger than the diameters of the first portion 213A and the third portion 213C. Specifically, the diameter of the first portion 213A of the alignment groove 213 substantially matches the diameter of the first portion 2200A of the body portion 2200 of the socket connector 220, the diameter of the second portion 213B of the alignment groove 213 substantially matches the diameter of the second portion 2200B of the body portion 2200 of the socket connector 220, and the diameter of the third portion 213C of the alignment groove 213 substantially matches the diameter of the third portion 2200C of the body portion 2200 of the socket connector 220. This design ensures that the socket connector 220 will not slide or fall out within the socket housing 210 after the upper housing 211 and the lower housing 212 are combined.

[0200] On the other hand, the upper shell 211 and the lower shell 212 each have a positioning groove 203, wherein the positioning groove 203 has a narrow and elongated profile. When the upper shell 211 and the lower shell 212 are combined, the positioning groove 203 of the upper shell 211 and the corresponding positioning groove 203 of the lower shell 212 will merge to form a narrow and elongated groove.

[0201] In some embodiments, the upper shell 211 and the lower shell 212 can be secured together by snap-fit ​​structures 215 located on each other's side surfaces. Specifically, one end of the upper shell 211 has a snap-fit ​​structure 215, while the other end has a groove 214. Similarly, one end of the lower shell 212 has a snap-fit ​​structure 215, while the other end has a groove 214. When the upper shell 211 and the lower shell 212 are assembled, the snap-fit ​​structure 215 of the upper shell 211 engages with the groove 214 of the lower shell 212, and the snap-fit ​​structure 215 of the lower shell 212 engages with the groove 214 of the upper shell 211, thereby securely joining the upper shell 211 and the lower shell 212.

[0202] In some embodiments, the socket housing 210 has a plurality of locking holes 216 in the direction of the mating surface 201 of the socket 200. In some embodiments, the socket housing 210 also has a plurality of positioning holes 217. Specifically, the upper shell 211 and the lower shell 212 each have one locking hole 216 and one positioning hole 217. In some embodiments, the locking hole 216 and the positioning hole 217 of the socket housing 210 may be located diagonally on the mating surface 201. In some embodiments, a limiting member 301 is installed in the locking hole 216.

[0203] Figure 7 This is a perspective view of the socket and connection panel of an embodiment, which will be discussed. Figure 1 The connection relationship between the socket 200 and the connection panel 300.

[0204] In some embodiments, the socket housing 210 of the socket 200 can be locked to the connecting panel 300, wherein the connecting panel 300 is locked to the socket housing 210 via a locking hole 216 located diagonally on the socket housing 210. In some embodiments, the connecting panel 300 has three openings, including two openings 350 and an opening 360 located between the two openings 350. The two openings 350 are positioned approximately aligned with and expose the locking hole 216 of the socket housing 210 of the socket 200. In some embodiments, the two openings 350 may communicate with the opening 360 (e.g., the boundary of the opening 350 adjacent to the opening 360 in the figure may not exist), in which case the two openings 350 are equivalent to two extensions of the opening 360.

[0205] On the other hand, opening 360 is disposed in the mating area (i.e., slot 2208) of the socket connector 220, which at least exposes the socket 200. In some embodiments, opening 360 also exposes a positioning hole 217 and a positioning groove 203. In some embodiments, opening 350 and opening 360 are not connected to each other. In some embodiments, the area of ​​opening 360 is larger than the area of ​​opening 350. In some embodiments, opening 360 has a stepped profile.

[0206] From another perspective, the outline of opening 360 has two recessed portions R1, wherein opening 350 is adjacent to the recessed portion R1 of opening 360.

[0207] The locking hole 216 of the socket housing 210 and the opening 350 of the connecting panel 300 have matching or similar dimensions. In some embodiments, the opening 350 of the connecting panel 300 is larger than the locking hole 216. The locking hole 216 is a through hole, with a first opening and a second opening formed on two surfaces of the socket housing 210, respectively. The locking mechanism includes inserting and positioning a limiting member 301 into the locking hole 216 of the socket housing 210. In some embodiments, the limiting member 301 includes a first end 301A, a second end 301B, and a main body portion 301C located between the first end 301A and the second end 301B. In some embodiments, the first end 301A, the second end 301B, and the main body portion 301C all have a circular cross-sectional profile, wherein the outer frame (diameter) of the first end 301A and the second end 301B is larger than the outer frame (diameter) of the main body portion 301C, and the outer frame (diameter) of the first end 301A is larger than the outer frame (diameter) of the second end 301B. On the other hand, the outer frame (diameter) of the second end 301B and the main body 301C is smaller than the outer frame (diameter) of the locking hole 216, while the outer frame (diameter) of the first end 301A is larger than the outer frame (diameter) of the locking hole 216. Therefore, when the limiting member 301 is placed into the locking hole 216, the second end 301B and the main body 301C of the limiting member 301 with the smaller diameter are first inserted into the locking hole 216 through the first opening. As the limiting member 301 moves into the locking hole 216, the first end 301A with the larger diameter can no longer enter the locking hole 216, causing the first end 301A of the limiting member 301 to abut against the outer wall surface of the socket housing 210. At this time, the second end 301B protrudes from the second opening through the locking hole 216 and is exposed.

[0208] The limiting member 301 has a through hole therethrough. In some embodiments, the limiting member 301 may be made of plastic, and the through hole of the limiting member 301 may have a smooth inner surface. In other embodiments, the limiting member 301 may be made of metal, and the through hole of the limiting member 301 may have a threaded inner surface.

[0209] In some embodiments, the positioning of the limiting member 301 in the locking hole 216 of the socket housing 210 further includes using a C-ring 302 (or auxiliary piece) to secure the limiting member 301. In some embodiments, the C-ring 302 is essentially a circular ring structure with an opening. The opening of the C-ring 302 is detachably configured to fit onto the main body portion 301C of the limiting member 301. That is, the inner diameter of the C-ring 302 is substantially the same as or slightly larger than the diameter of the main body portion 301C of the limiting member 301, so that the C-ring 302 can be securely fitted onto the main body portion 301C of the limiting member 301. On the other hand, the outer diameter of the C-ring 302 is larger than the diameter of the locking hole 216 of the socket housing 210 (i.e., the diameter of the opening of the C-ring 302 adjacent to the locking hole 216), which will prevent the C-ring 302 from sliding into the locking hole 216 and abutting against the surface of the socket housing 210, and will help to further fix the limiting member 301 to the socket housing 210.

[0210] Next, screw 304 is inserted from the other side of connecting panel 300 through opening 350 into through hole of limiting member 301. In some embodiments, fixing connecting panel 300 to socket housing 210 of socket 200 also includes using a washer 303, wherein washer 303 has a ring-shaped structure, and screw 304 can pass through washer 303 before entering through opening 350 and through hole of limiting member 301. In some embodiments, outer diameter of washer 303 is larger than diameter of opening 350 of connecting panel 300, so washer 303 can completely abut against one surface of connecting panel 300, thereby fixing connecting panel 300 to socket housing 210 of socket 200.

[0211] Figure 8 This is a perspective view of the gasket and screw in the embodiment, which will be discussed. Figure 7 Detailed structure of screw 304. In some embodiments, screw 304 has a screw head 304H and a screw pin 304B. Screw pin 304B has a top 3040 and a bottom 3042, wherein the top 3040 is located between the bottom 3042 and the screw head 304H. In some embodiments, the top 3040 of screw pin 304B has a smooth surface, while the bottom 3042 of screw pin 304B has a threaded surface. In some embodiments, washer 303 has a washer opening 303O. In some embodiments, the diameter of washer opening 303O is larger than the diameter of screw pin 304B and smaller than the diameter of screw head 304H. In some embodiments, the outer diameter of washer 303 is larger than the diameter of screw head 304H. In some embodiments, the outer diameter of washer 303 is about 6 mm or more, while the diameter of screw pin 304B is about 5 mm or less.

[0212] Figure 9This is a schematic diagram of the connection panel according to an embodiment. In some embodiments, the opening 350 of the connection panel 300 can be adjusted in size as needed. In some embodiments, the diameter of the opening 350 of the connection panel 300 is larger than the diameter of the screw pin 304B. In some embodiments, if the diameter of the screw pin 304B is about 2.5 mm, the diameter of the opening 350 can be about 6.8 mm.

[0213] Figure 10 This is a cross-sectional view of the connection panel and socket in the embodiment. The mechanism for locking the socket housing 210 of the socket 200 to the connection panel 300 will be discussed below. As mentioned earlier, the limiting member 301 is inserted from the outer surface (or first surface) 210A of the socket housing 210 into the locking hole 216 on the socket housing 210. Since the length of the main body portion 301C of the limiting member 301 is slightly longer than the length of the locking hole 216, a portion of the main body portion 301C of the limiting member 301 protrudes from the inner surface (or second surface) 210B of the socket housing 210, exposing the second end 301B. The C-shaped ring 302 fitted into the main body portion 301C abuts against (is located) between the inner surface 210B of the socket housing 210 and the second end 301B of the limiting member 301. Therefore, by setting the C-ring 302, the limiting member 301 can be fixed in the locking hole 216 of the socket housing 210 without falling off and also has the function of buffering friction. However, since the main body 301C of the limiting member 301 has a relatively small diameter, there is a floating space between the main body 301C of the limiting member 301 and the locking hole 216. That is to say, although the limiting member 301 is fixed to the socket housing 210, the limiting member 301 can still slide in the locking hole 216. This floating space provides more flexibility for the mating of the socket 200 and the plug 100.

[0214] Next, the socket 200 can be pressed against the connecting panel 300. More specifically, the opening 350 of the connecting panel 300 is generally aligned with the through hole of the limiting member 301, and one side of the connecting panel 300 can abut against the first end 301A of the limiting member 301. Next, the washer 303 is pressed against the other side of the connecting panel 300, and the screw 304 is inserted through the opening of the washer 303 and the opening 350 of the connecting panel 300 and coupled to the limiting member 301.

[0215] Please refer to Figure 10 The socket housing 210 has a locking hole 216 with a diameter L1, while the opening 350 of the connecting panel 300 has a diameter L2. On the other hand, the main body portion 301C of the limiting member 301 has a diameter L3, which is smaller than the diameter L1 of the locking hole 216. Furthermore, the screw 304 has a diameter L4, which is smaller than the diameter L2 of the opening 350 of the connecting panel 300.

[0216] Therefore, the main body 301C of the limiting member 301 can slide within the locking hole 216, and the maximum floating distance is (diameter L1 - diameter L3). Similarly, the screw 304 can slide within the opening 350 of the connecting panel 300, and the maximum floating distance is (diameter L2 - diameter L4). Thus, assuming the position of the connecting panel 300 is fixed, the socket housing 210 can slide relative to the connecting panel 300, and the maximum floating dimension is (diameter L1 - diameter L3) + (diameter L2 - diameter L4). In some embodiments, the difference between the outer diameter of the gasket 303 and the diameter L2 of the opening 350 is greater than or equal to the difference between diameter L2 and diameter L4. In some embodiments, the difference between the outer diameter of the C-ring 302 and the diameter L1 of the locking hole 216 is greater than or equal to the difference between diameter L1 and diameter L3. This configuration ensures that during the sliding process, the outer edge of the pad 303 is not partially within the projection of the opening 350, and the outer edge of the C-ring 302 is not partially within the projection of the locking hole 216.

[0217] In some embodiments, the locking hole 216 may be a non-circular (e.g., quadrilateral) through hole, and the contour of the main body portion 301C of the limiting member 301 located within the locking hole 216 is approximately consistent with but smaller than the surface contour of the locking hole 216, thus allowing for floating space between them. Similarly, the contour of the bottom 3042 of the screw 304 and the contour of the opening 350 may be non-circular and approximately consistent with but smaller than the opening, thus allowing for floating space between them.

[0218] Therefore, the floating range between the socket housing 210 and the connecting panel 300 can be adjusted according to usage requirements by designing the main body 301C of the limiting member 301, the locking hole 216, the opening 350 on the connecting panel 300, or the size of the screw 304, to meet different usage needs. In some embodiments, a nut can be used to lock onto the thread of the bottom 3042. By adjusting the locking force of the nut, the friction between the socket housing 210 and the connecting panel 300 can be adjusted, so that after relative movement between the socket housing 210 and the connecting panel 300, the relative position of the socket housing 210 and the connecting panel 300 is fixed due to friction.

[0219] In other words, the limiting member 301, C-ring 302, gasket 303, and screw 304 constitute a limiting mechanism, allowing the socket housing 210 and the connecting panel 300 to be relatively movable together. More specifically, the limiting mechanism clamps at least a portion of the connecting panel 300 and the socket housing 210 between them, such that at least a portion of the connecting panel 300 and the socket housing 210 is located between the two ends of the limiting mechanism. The limiting mechanism can move relative to the socket housing 210 within a first preset range. Alternatively, the limiting mechanism can move relative to the connecting panel 300 within a second preset range. Therefore, there is a floating mechanism between the socket housing 210 and the connecting panel 300 with either a first preset range or a second preset range. When both floating mechanisms are provided, there is a maximum floating mechanism between the socket housing 210 and the connecting panel 300 with the first preset range plus the second preset range. The socket housing 210, the connecting panel 300, and the limiting mechanism (limiting member 301, C-ring 302, gasket 303, and screw 304) can be collectively referred to as the connector housing.

[0220] On the other hand, referring to positioning hole 217, positioning hole 217 has a first portion 217A and a second portion 217B that are connected to each other. In some embodiments, the first portion 217A has a gradually narrowing profile. For example, the first portion 217A has the largest width (or diameter) on the side closer to the connecting panel 300 and the smallest width (or diameter) on the side farther from the connecting panel 300. Furthermore, the second portion 217B has a generally uniform width (or diameter). The profile of the first portion 217A of positioning hole 217 facilitates the insertion of the plug's guide post into positioning hole 217.

[0221] Figure 11A This is a perspective view of the socket and plug in an embodiment. Figure 11B This is a 3D diagram of the plug's conductive structure and the circuit board. Figure 11C This is a 3D diagram of a plug, which will be discussed. Figure 1 The connection relationship between the plug 100, the socket 200 and the circuit board 400, and the detailed structure of the plug 100.

[0222] refer to Figure 11A In some embodiments, the plug 100 includes a plug housing 110 and a plurality of conductive terminals (or plug connectors) 120 located inside the plug housing 110. In some embodiments, contact terminals 124 of the conductive terminals 120 extend outward from the mating surface 101 of the plug housing 110 (i.e., in the direction of abutment against the socket 200). In some embodiments, the plug housing 110 includes guide posts 130 extending outward from the mating surface 101 of the plug housing 110. In some embodiments, the foremost point of the guide post 130 is further forward than the foremost point of the conductive terminals 120.

[0223] Furthermore, the connection panel 300 can be secured to the surface of the socket housing 210 of the socket 200 by screws through the opening 350, and the conductive terminals 120 and guide posts 130 of the plug 100 will pass through the opening 360 of the connection panel 300 and be connected or coupled to the socket 200.

[0224] In detail, when the plug 100 is inserted into the socket 200, the guide post 130 of the plug 100 first passes through the opening 360 of the connecting panel 300 and is inserted into the positioning hole 217 of the corresponding socket 200. Then, the conductive terminals 120 of the plug 100 pass through the opening 360 of the connecting panel 300 and are respectively inserted into the socket connector 220 of the corresponding socket 200, thereby establishing an electrical connection between the conductive terminals 120 of the plug 100 and the socket connector 220 of the socket 200.

[0225] Please refer to Figure 11B . Figure 11B This diagram depicts the plug housing 110 of the plug 100 when the conductive terminals 120 are separated. In some embodiments, the plug housing 110 has two receiving spaces 152, which are separated by a wall of the plug housing 110. The conductive terminals 120 can be inserted into the plug housing 110 through the corresponding receiving spaces 152 and are electrically isolated from each other, protruding outward from the mating surface 101 (e.g., Figure 11C (As shown).

[0226] In some embodiments, the conductive terminal 120 includes a conductive terminal base 121. In some embodiments, the conductive terminal base 121 is a cuboid or cube, with a guide groove 122 on each of its opposite sides along the mating direction for engaging with the plug housing 110. In some embodiments, the guide groove 122 may be a recessed area located on the side surface of the conductive terminal base 121.

[0227] In some embodiments, the conductive terminal 120 also has a plurality of pins 123 extending downward from the bottom of the conductive terminal base 121 and used to connect the conductive terminal 120 to the circuit board 400. That is, the pins 123 can be inserted into and mounted to holes on the surface of the circuit board 400 and electrically connected to the circuit board 400 by a suitable means (e.g., soldering).

[0228] On the other hand, each conductive terminal 120 also has a contact terminal 124 extending forward (in the mating direction) from one side wall of the conductive terminal base 121. The contact terminal 124 has a generally cylindrical profile. In some embodiments, the surface of the contact terminal 124 also has a retaining ring 1240 located in the middle section of the contact terminal 124, wherein the retaining ring 1240 may be a groove surrounding the cylindrical profile of the contact terminal 124. In some embodiments, when the conductive terminal 120 is installed to the plug housing 110, the contact terminal 124 of the conductive terminal 120 will pass through a through hole in the plug housing 110, and the retaining ring 1240 will be inserted into the through hole in the plug housing 110, thereby fixing the contact terminal 124 to the plug housing 110.

[0229] In some embodiments, the inner surface of each accommodating space 152 has a plurality of raised guide strips 111 for embedding into guide grooves 122 on the conductive terminal base 121. For example, when the conductive terminal 120 is inserted into the accommodating space 152 of the plug housing 110, the guide groove 122 can slide along the corresponding guide strip 111 and further insert the conductive terminal base 121 into the plug housing 110 in a predetermined direction.

[0230] In some embodiments, the plug housing 110 further includes a positioning hole 112, which is a hollow structure configured for positioning and connecting to the circuit board 400. Similarly, in some embodiments, the circuit board 400 also includes a positioning hole 402, which is a hollow structure. For example, the conductive terminal 120 can be first mounted on the circuit board 400, and then the conductive terminal 120 can be inserted into the receiving space 152 of the plug housing 110. After the conductive terminal 120 is mounted on the plug housing 110, the positioning hole 112 of the plug housing 110 will align with the positioning hole 402 on the circuit board 400. Then, the plug housing 110 can be secured to the circuit board 400 by means of a fastening component (e.g., a screw) passing through the positioning hole 112 and the positioning hole 402.

[0231] Please refer to Figure 11C At the mating surface 101 of the plug 100, the contact terminal 124 of the conductive terminal 120 protrudes from one side of the plug housing 110. In some embodiments, the plug 100 also has positioning components 102 extending outward from the upper and lower sides of the plug housing 110, and an isolation component (or guide plate) 103 extending into the plug housing 110 and located in the middle of the conductive terminal 120. In some embodiments, the foremost point of the isolation component 103 is located after the foremost point of the guide post 130, but before the foremost point of the conductive terminal 120.

[0232] In some embodiments, the positioning component 102 has a plate-like structure and covers the conductive terminal 120 by two positioning components 102. In some embodiments, after the plug 100 is engaged with the socket 200, the positioning component 102 of the plug housing 110 may cover and contact at least a portion of the side surface of the socket housing 210 of the socket 200.

[0233] In some embodiments, the mating surface 101 has non-adjacent guide posts 130 at its diagonal corners. In some embodiments, the end of the guide post 130 facing the mating surface 101 has a tapered end 130E. That is, the tip of the guide post 130 has a gradually narrowing profile.

[0234] In some embodiments, the gradually narrowing profile of the guide post 130 allows the plug 100 to have a margin of error (i.e., the dimensional difference between the tapered end and the non-tapered end) to allow the tapered end 130E of the guide post 130 to be inserted into the positioning hole 217 through the opening of the connecting panel 300, even if the plug 100 is not perfectly aligned with the positioning hole 217 of the socket 200. In other words, the guide post 130 can be gradually guided into the correct engagement position of the positioning hole 217 by inserting the tapered end 130E (at which time the socket 200 can move relative to the connecting panel 300). In some embodiments, the diameter of the end of the tapered end 130E facing the engagement surface 101 is smaller than the diameter of the other end of the tapered end 130E (i.e., the end facing away from the engagement surface 101). In some embodiments, the diameter of the other end of the tapered end 130E (i.e., the end facing away from the engagement surface 101) may be less than or equal to the diameter of the guide post 130.

[0235] In some embodiments, the guide post 130 and the conductive terminal 120 or positioning assembly 102 have substantially the same outward distance from the plug housing 110.

[0236] Please refer to the reply. Figure 11AWhen the plug 100 is engaged with the socket 200, the conductive terminals 120, guide posts 130, positioning components 102, and isolation components 103 of the plug 100 will pass through the opening 360 of the connection panel 300 and be inserted into the socket 200. Specifically, the conductive terminals 120 of the plug 100 will pass through the opening 360 of the connection panel 300 and be inserted into the socket connector 220 of the socket 200. The guide posts 130 of the plug 100 will pass through the opening 360 of the connection panel 300 and be inserted into the positioning hole 217 of the socket 200. The positioning components 102 of the plug 100 will pass through the opening 360 of the connection panel 300 and cover the socket housing 210 of the socket 200 from both the top and bottom. The isolation components 103 of the plug 100 will pass through the opening 360 of the connection panel 300 and be inserted into the positioning groove 203 of the socket 200. As mentioned above, since the guide post 130 has the farthest extension distance, when the plug 100 is inserted into the socket 200, the guide post 130 will first enter the positioning hole 217, and then the isolation component 103 and the conductive terminal 120 will enter the positioning groove 203 and the socket connector 220 respectively.

[0237] Figure 12 This is a perspective view of the connector assembly in an embodiment. The icon represents a bus connector assembly, also known as connector assembly M2. It should be understood that... Figure 12 Connector assembly M2 and Figures 1 to 11C The connector component M1 discussed is similar. Therefore, similar components will use the same component notation, and related details will not be repeated. Figures 12 to 18B The detailed structure of connector assembly M2 will be discussed.

[0238] exist Figure 12 In one embodiment, the connector assembly M2 includes a connector 1, a plurality of conductive strip groups 60, a plurality of sockets 200, and a plurality of plugs 100. Specifically, the connector assembly M2 has two conductive strip groups 60, each electrically connected to the connector 1 and extending towards both sides of the connector 1. On the other hand, the connector assembly M2 has two sockets 200 and two plugs 100, wherein each socket 200 is electrically connected to a corresponding conductive strip group 60, and each plug 100 is connected to a corresponding socket 200.

[0239] It should be understood that, although no accompanying image was attached... Figure 12 However, connector assembly M2 also has the same characteristics. Figure 1 The connector assembly M1 shows the connection panel 300 and the circuit board 400.

[0240] Figure 13 This is a perspective view of the conductive terminal structure of an embodiment, which will be discussed. Figure 12 The detailed structure of the conductive terminal structure 12 inside the housing 11 of connector 1.

[0241] Each of the conductive terminal structures 12 has a pair of conductive blocks 1201 and a pair of spring contacts 1210, wherein each spring contact 1210 is disposed on a corresponding conductive block 1201. In some embodiments, the conductive blocks 1201 of each conductive terminal structure 12 are separated from each other.

[0242] Similarly, the conductive block 1201 may have multiple holes 1202, while the spring piece 1210 has multiple holes 1212, wherein the holes 1212 of the spring piece 1210 may correspond to some of the holes 1202 of the conductive block 1201. This allows fastening components (such as rivets or screws) to pass through the holes 1212 of the spring piece 1210 and the holes 1202 of the conductive block 1201, thus securing the spring piece 1210 and the conductive block 1201 together. In some embodiments, the fixing point between the conductive block 1201 and the spring piece 1210 has a groove, so that the outer surface of the spring piece 1210 after fixing is flush with the exposed outer surface of the conductive block 1201. In some embodiments, other holes 1202 of the conductive block 1201 do not correspond to the holes 1212 of the spring piece 1210; these holes 1202 can be used to fix other components to the conductive block 1201.

[0243] Figure 14 This is a perspective view of the conductive terminal structure and conductive strip assembly as an embodiment. It will be discussed... Figure 12 The connection relationship between the conductive terminal structure 12 of connector 1 and the conductive strip group 60.

[0244] In some embodiments, two second conductive strips 60B can be fixed to one of the conductive terminal structures 12. Specifically, each of the second conductive strips 60B has a fixing portion that is fixedly connected to the conductive block 1201. Furthermore, the connecting portions of the second conductive strips 60B and the conductive blocks 1201 are arranged alternately. In some embodiments, the fixing portion of the second conductive strip 60B is fixed to the outer surface of the corresponding conductive block 1201 (the side away from the other conductive terminal structure 12). A pair of conductive blocks 1201 of the conductive terminal structure 12 can be simultaneously fixed and electrically connected to both second conductive strips 60B; or they can be fixed and electrically connected to only one of the two second conductive strips 60B respectively, but electrically isolated from the other.

[0245] like Figure 13 and Figure 2BAs mentioned, the conductive block 1201 of the conductive terminal structure 12 has a hole 1202, and the spring piece 1210 has a hole 1212. In some embodiments, both second conductive strips 60B also have holes. Then, the two second conductive strips 60B can be fixed together with their corresponding conductive terminal structures 12 by means of a fixing component 1220 passing through the holes of the two second conductive strips 60B, as well as the holes of the spring piece 1210 and the conductive block 1201. In other words, the two second conductive strips 60B and the conductive terminal structure 12 are electrically connected to each other through contact. In some embodiments, the fixing component 1220 can be a rivet, a screw, or other suitable fixing component.

[0246] Next, after fixing the two second conductive strips 60B to one of the conductive terminal structures 12, the two first conductive strips 60A can be fixed to the other conductive terminal structure 12. The connection relationship between the first conductive strip 60A and its corresponding conductive terminal structure 12 is basically the same as the connection relationship between the second conductive strip 60B and its corresponding conductive terminal structure 12, so it will not be described again. In other embodiments, the two first conductive strips 60A can be fixed to one conductive terminal structure 12 first, and then the two second conductive strips 60B can be fixed to the other conductive terminal structure 12.

[0247] In some embodiments, each of the conductive strips 60 can be bent to form a receiving space 610 on one side of the conductive terminal structure 12. This receiving space 610 helps to secure the housing 11 of the connector 1 to other components.

[0248] Figure 15 This is a perspective view of the connector housing in an embodiment, which will be discussed. Figure 12 Detailed structure of the housing 11 of connector 1.

[0249] The housing 11 has wings 13 extending to opposite sides of the housing 11. In some embodiments, each wing 13 has a guide structure 1300 extending in a direction opposite to the slot 10 of the housing 11. In some embodiments, each guide structure 1300 has a slot 1302. In some embodiments, the housing 11 also has two snap-fit ​​structures 1140 extending in a direction opposite to the slot 10 of the housing 11. Furthermore, a plurality of recesses 1120 are also provided in the housing 11.

[0250] Figure 16A , Figure 16B and Figure 16C This is a perspective view of the conductive terminal structure and housing in an embodiment, which will be discussed. Figure 12 The connection relationship between the housing 11 of connector 1 and the conductive terminal structure 12.

[0251] Please refer to this first. Figure 16A In some embodiments, it can be as follows: Figure 14 The process discussed involves first installing the conductive strip assembly 60 onto the conductive terminal structure 12, and then inserting the conductive terminal structures 12 into the housing 11. However, for ease of viewing, Figure 16A The conductive strip group 60 was not drawn.

[0252] First, insert the two conductive terminal structures 12 into the housing 11 along the opposite sides of the snap-fit ​​structure 1140. In this way, the snap-fit ​​structure 1140 will be located between the two conductive terminal structures 12, and the contact terminals 1215 of the spring tabs 1210 of the conductive terminal structures 12 will extend to the slots 10 of the housing 11.

[0253] Furthermore, the protruding structure 1214 of the spring tab 1210 of the conductive terminal structure 12 will be embedded into the groove 1120 of the housing 11. This design can restrict the movement of the conductive terminal structure 12 in the plane perpendicular to the slot 10, so as to accurately fix the conductive terminal structure 12 to the housing 11.

[0254] Please refer to Figure 16A and Figure 16B After the conductive terminal structure 12 is inserted into the housing 11, the conductive terminal structure 12 can be further fixed in the housing 11 by combining a cover plate 14 with the housing 11.

[0255] like Figure 16B As shown, after the conductive terminal structure 12 is inserted into the housing 11, the guide structure 1300 of the housing 11 will be disposed in the accommodating space 610 formed by the conductive strip assembly 60. From another perspective, the conductive strip assembly 60 can be designed to be curved along the shape of the guide structure 1300 of the housing 11, which helps to minimize the overall component size.

[0256] On the other hand, the cover plate 14 includes a substrate 1410. In some embodiments, the substrate 1410 has a plurality of vents 1412. Since the conductive terminal structure 12 and the metal material of the conductive strip assembly 60 within the housing 11 may reach high temperatures during energization, the vents 1412 on the substrate 1410 will help dissipate heat to prevent the component from overheating. The cover plate 14 also includes a guide structure 1430 and a plurality of snap-fit ​​structures 1420 connected to the substrate 1410 and extending from the substrate 1410 toward the housing 11. In some embodiments, the guide structure 1430 has a slot 1432. In some embodiments, the snap-fit ​​structures 1420 have a slot 1422.

[0257] Next, the cover plate 14 can be engaged with the housing 11. For example... Figure 16Band Figure 16C As shown, the snap-fit ​​structure 1420 of the cover plate 14 is inserted into the slot 1302 of the guide structure 1300 of the housing 11. The guide structure 1430 of the cover plate 14 is also inserted into the housing 11 and positioned between the two conductive terminal structures 12, thus electrically isolating the two conductive terminal structures 12. Furthermore, the snap-fit ​​structure 1140 of the housing 11 is also inserted into the slot 1432 of the guide structure 1430 of the cover plate 14 and engaged. In this way, the cover plate 14 and the housing 11 can be tightly joined, so that the conductive terminal structures 12 are securely disposed within the housing 11.

[0258] In some embodiments, connector 1 may have only one slot 10, and the two springs 1210 of conductive terminal structure 12 are respectively fixed to the corresponding conductive blocks 1201, and are independent and electrically isolated from each other. The first conductive strip 60A and the second conductive strip 60B are each fixed and electrically connected to the corresponding conductive blocks 1201, and extend in the directions of the two sides of connector 1 respectively.

[0259] Figure 17 This is a perspective view of the conductive strip assembly and socket in an embodiment, which will be discussed. Figure 12 The connection relationship between the conductive strip group 60 and the socket 200.

[0260] In some embodiments, the socket 200 has a socket housing 210 and a plurality of socket connectors 220. In some embodiments, each socket 200 has two socket connectors 220. The two socket connectors 220 are aligned in a left-right direction. In some embodiments, the socket connectors 220 may comprise copper, a copper alloy, or a similar conductive material.

[0261] In some embodiments, each receptacle connector 220 has a body portion 2200 and a conductive plate 2220, which are interconnected. The body portion 2200 and the conductive plate 2220 may be integrally formed. The conductive plate 2220 of one receptacle connector 220 contacts and is electrically connected to the upper surface of the first conductive strip 60A. On the other hand, the conductive plate 2220 of another receptacle connector 220 contacts and is electrically connected to the lower surface of the second conductive strip 60B, wherein the conductive plate 2220 of the other receptacle connector 220 will simultaneously be located on the upper surface of a portion of the first conductive strip 60A. However, this portion of the first conductive strip 60A may be covered with an insulating film or insulating element, so that the conductive plate 2220 of the other receptacle connector 220 will not make electrical contact with the first conductive strip 60A.

[0262] The socket housing 210 includes an upper housing 211 and a lower housing 212. In some embodiments, the upper housing 211 and the lower housing 212, when assembled, form alignment grooves 213 that correspond to the shape of the body portion 2200 of the socket connector 220, thereby positioning the socket connector 220 within the socket housing 210. Specifically, each of the upper housing 211 and the lower housing 212 has two alignment grooves 213, wherein the alignment grooves 213 have a generally semi-circular outline. When the upper housing 211 and the lower housing 212 are joined, the alignment grooves 213 of the upper housing 211 and their corresponding alignment grooves 213 of the lower housing 212 merge to form circular receiving grooves, in which the socket connector 220, having a cylindrical structure, can be positioned.

[0263] On the other hand, the upper shell 211 and the lower shell 212 each have a positioning groove 203, wherein the positioning groove 203 has a narrow and elongated profile. When the upper shell 211 and the lower shell 212 are combined, the positioning groove 203 of the upper shell 211 and the corresponding positioning groove 203 of the lower shell 212 will merge to form a narrow and elongated groove.

[0264] Furthermore, the upper shell 211 and the lower shell 212 each have an accommodating space 204, wherein the accommodating space 204 has a long and narrow profile. When the upper shell 211 and the lower shell 212 are combined, the accommodating space 204 of the upper shell 211 and the corresponding accommodating space 204 of the lower shell 212 will merge to form a long and narrow groove, and the conductive plate 2220 of the socket connector 220, a part of the first conductive strip 60A and a part of the second conductive strip 60B will be positioned in this long and narrow groove.

[0265] In some embodiments, the upper shell 211 and the lower shell 212 can be joined together by a snap-fit ​​structure. Furthermore, a nut 230 can be provided in the lower shell 212, and a screw hole 232 can be provided in the upper shell 211, with the screw hole 232 of the upper shell 211 corresponding to the nut 230 of the lower shell 212. Therefore, after the upper shell 211 and the lower shell 212 are joined, a screw can be used to lock the upper shell 211 to the nut 230 of the lower shell 212 via the screw hole 232. In this way, the upper shell 211 and the lower shell 212 can be securely joined together.

[0266] In some embodiments, the socket housing 210 has a plurality of locking holes 216 and a plurality of positioning holes 217 in the direction of the mating surface of the socket 200. In some embodiments, a limiting member 301 is installed in the locking holes 216. In some embodiments, the socket housing 210 can be relatively movably connected to a connecting panel 300 as discussed above, and the socket housing 210 has a floating space relative to the connecting panel 300.

[0267] Figure 18A and Figure 18BThis is a perspective view of the plug and circuit board of an embodiment, which will be discussed. Figure 12 Detailed structure of plug 100.

[0268] Figure 18A In some embodiments, the plug 100 includes a plug housing 110 and a plurality of conductive terminals 120 located inside the plug housing 110. In some embodiments, the conductive terminals 120 may first be mounted on a circuit board (e.g., the circuit board 400 described above), and then the conductive terminals 120 may be inserted into the receiving space 152 of the plug housing 110.

[0269] In some embodiments, the plug housing 110 further includes a plurality of recesses 1103 communicating with the receiving space 152. The plug housing 110 also includes a plurality of protrusions 1104.

[0270] After the conductive terminal 120 is inserted into the plug housing 110, the conductive terminal 120 can be further fixed in the plug housing 110 by combining a cover plate 160 with the plug housing 110.

[0271] Please refer to cover plate 160, which includes a substrate 1610. In some embodiments, substrate 1610 has a plurality of vents 1612. Since the conductive terminals 120 within the plug housing 110 may generate high temperatures due to the conduction of large currents during energization of the conductive terminals 120, the vents 1612 on substrate 1610 will help dissipate heat to prevent the component from overheating. Cover plate 160 also includes a plurality of snap-fit ​​structures 1620 located at the lower edge of substrate 1610 and a plurality of snap-fit ​​structures 1630 located at the upper edge of substrate 1610.

[0272] Next, the cover plate 160 can be engaged with the plug housing 110. For example... Figures 18A to 18B As shown, first, the snap-fit ​​structures 1620 of the cover plate 160 abut against the inner edge of the protrusion structure 1104 of the plug housing 110. Next, the cover plate 160 is pushed towards the plug housing 110, and the snap-fit ​​structures 1630 are engaged into the grooves 1103 of the plug housing 110. In this way, the cover plate 160 and the plug housing 110 are tightly joined, and the conductive terminal 120 is securely positioned within the plug housing 110.

[0273] Figure 19A and Figure 19B This is a schematic diagram illustrating the relative relationship between the plug, socket, and connection panel in an embodiment, which will discuss a schematic diagram of inserting the plug 100 into the socket 200 through the opening 360 of the connection panel 300. Figure 19A This is a plan view of the socket 200 and the connection panel 300. Figure 19B This is a cross-sectional view of the socket 200, the connection panel 300, and the plug 100.

[0274] Please refer to Figure 19A and Figure 19B In some embodiments, the socket 200 and the connecting panel 300 may have errors during installation, or tolerances may exist in the manufacturing process of the conductive strip assembly 60 and the socket 200, causing the socket 200 and the connecting panel 300 to shift. Figure 19A and Figure 19B For example, taking the position of the connecting panel 300 as a reference, the socket 200 is offset upward relative to the connecting panel 300, which further causes the positioning hole 217, the socket connector 220, and the positioning groove 203 of the socket 200 to be offset upward. Generally, the offset of the socket will cause misalignment in the subsequent plug-socket mating process, and the design of the present invention can solve this problem.

[0275] Please refer to Figure 19B When the plug 100 moves toward the socket 200, because the guide post 130 of the plug 100 has the longest extension distance, it will first pass through the opening 360 of the connecting panel 300 and move toward the positioning hole 217 of the socket 200. Although the offset of the socket 200 will cause the positioning hole 217 and the guide post 130 to not be perfectly aligned, the end 130E of the guide post 130 can contact the surface of the first portion 217A of the positioning hole 217. As mentioned above, the first portion 217A of the positioning hole 217 has a gradually narrowing profile, and this inclined surface will help guide the guide post 130 into the positioning hole 217. In addition, the gradually narrowing profile of the end 130E of the guide post 130 also helps guide the guide post 130 into the positioning hole 217 of the socket 200.

[0276] As mentioned above, because the screw 304 has floating space within the opening 350 of the connecting panel 300, and the limiting member 301 has floating space within the locking hole 216, the socket 200 can move relative to the connecting panel 300. Therefore, as the guide post 130 of the plug 100 enters the positioning hole 217 of the socket 200, the guide post 130 will exert a downward force on the socket 200, causing the socket 200 to be moved and corrected to an ideal position.

[0277] In some embodiments, the guide post 130 has a larger floating space between openings 360 than the screw 304 has a larger floating space within opening 350, which allows for greater tolerance to insert the guide post 130 into the positioning hole 217.

[0278] Figure 19AThis discussion focuses only on an example where the socket 200 and the connection panel 300 are offset in one direction. However, it should be understood that embodiments of the invention can be applied to situations where the socket 200 and the connection panel 300 are offset in different directions. Furthermore, embodiments of the invention can be applied to situations where the socket 200 and the plug 100 are offset.

[0279] The foregoing summary outlines several features of the embodiments, enabling those skilled in the art to better understand the nature of the invention. Those skilled in the art will understand that the invention can be readily used as a basis for designing or modifying other processes and structures to achieve the same purpose and / or attain the same advantages of the embodiments described herein. Those skilled in the art will also recognize that such equivalent constructions do not depart from the spirit and scope of the invention, and that various changes, substitutions, and modifications can be made without departing from the spirit and scope of the invention.
