Abstract
Description
Technical Field
[0001] This invention relates to the field of connector technology, and more particularly to an adapter connector and a corner connector. Background Technology
[0002] In fields such as new energy vehicles, various corner connectors are used to connect devices to meet the requirements of compact structure and rapid installation. Existing corner connectors connect one end to the wiring harness and the other end to the printed circuit board (PCB) on the device. Electrical connections between devices are achieved in two main ways: One is a one-piece soldering method after mating. The soldering pins on the mating end of the corner connector are inserted into pads and vias on the PCB. The positioning pins and other structures of the corner connector ensure the alignment accuracy between the soldering pins and the pads, preventing misalignment. Wave soldering, reflow soldering, or manual soldering are used to solder the soldering pins and pads together and then encapsulate them. However, due to the high temperature of wave soldering, the stress changes caused by thermal shock and positional tolerances of different materials after soldering can easily lead to defects such as cold solder joints. The second method is the tail plug-in cable exit method, in which the positioning pin of the mating end of the corner connector is inserted into the positioning hole on the PCB to ensure precise matching. The tail plug-in is connected to a cable, and the PCB pads are connected to the tail plug-in through the conductive parts of the corner connector. However, the tail plug-in cable exit method requires sufficient operating space at the tail end of the corner connector, otherwise it will affect the smooth installation and removal of the plug-in. Therefore, both of the above methods limit the application scenarios. Summary of the Invention
[0003] One embodiment of the present invention aims to provide an adapter connector and a corner connector that are versatile and easy to operate.
[0004] One embodiment of the present invention adopts the following technical solution:
[0005] An adapter connector, comprising:
[0006] The base includes a seat body and a first protrusion protruding from the seat body along a first direction. The first protrusion has a first cavity, and the first cavity has an opening on the side opposite to the seat body.
[0007] A power female terminal is inserted through the base body, with one end extending out of the base body for electrical connection with the circuit board, and the other end being a first socket exposed in the first cavity. Both the first socket and the first cavity are used for insertion into a corner socket.
[0008] In some embodiments, the outer side of the first protrusion extends along the first direction and is provided with guide ribs for alignment in conjunction with the mounting panel on the device.
[0009] In some embodiments, the base body is provided with clamping arms on both sides along the second direction, the clamping arms clamping the two sides of the power female terminal, and the flange at the end of the clamping arm is provided at the end of the first socket.
[0010] In some embodiments, the side of the base away from the first protrusion is provided with a positioning post and / or an elastic buckle, the circuit board has a positioning hole, and the positioning post is inserted into the positioning hole; the circuit board has a through hole, and the elastic buckle can pass through the through hole and abut against the side of the circuit board away from the base.
[0011] In some embodiments, the base body has a support platform on the side opposite to the first protrusion, and the support platform supports the circuit board.
[0012] In some embodiments, a signal female terminal is further included, which passes through the base body. The base body also has a second protrusion with a second cavity. The second cavity has an opening on the side opposite to the base body. One end of the signal female terminal extends out of the base body for connection with a circuit board, and the other end is a second socket exposed in the second cavity. Both the second socket and the second cavity are used for connection with a corner socket.
[0013] An angular connector includes an angular socket and an adapter connector as described in any of the preceding claims. The angular socket includes a terminal module, the terminal module including an insulating core and a power male terminal passing through the insulating core. The insulating core is inserted into a first cavity, and the power male terminal is inserted into a first socket.
[0014] In some embodiments, the corner socket is detachably connected to the mounting panel of the device. The mounting panel has an opening, through which a first protrusion passes. A guide rib extends along a first direction on the outer side of the first protrusion and is used to align with the opening.
[0015] In some embodiments, the corner socket is provided with a positioning pin, and the mounting panel is provided with a positioning hole, and the positioning pin is inserted into the positioning hole.
[0016] In some embodiments, the corner socket further includes a shielding housing covering the periphery of the insulating core, the end of the shielding housing being provided with contact feet, the contact feet contacting the mounting panel to form electromagnetic shielding.
[0017] The beneficial effects of one embodiment of the present invention are as follows:
[0018] One embodiment of the present invention provides an adapter connector and a corner connector. One end of the female power terminal is electrically connected to the circuit board, and the first socket at the other end is used to connect to the male power terminal on the corner socket, thereby realizing the electrical connection between the circuit board and the male power terminal on the corner socket through the female power terminal. The first cavity is used to connect to the structural component on the corner socket, realizing the mechanical structure fixation. That is, the adapter connector is used for electrical and mechanical connection with the circuit board and the corner socket on the device, respectively, realizing the adapter between the circuit board and the corner socket. The adapter connector is pre-connected to the circuit board. In use, the corner socket and the adapter connector are plugged in, and the cable of another device is plugged into the adapter socket. The adapter connector has one end soldered to the circuit board and the other end plugged into the corner socket. This connection method differs from the integrated soldering method and the rear-plug-out method, avoiding issues such as high resistance and current-cutting obstruction caused by stress changes due to thermal shock and positional tolerances after welding. It also requires less installation space, adapting to smaller space needs and enabling rapid installation and disassembly in confined or limited spaces. The first socket and first cavity are used for plugging into the corner socket, ensuring high reliability and avoiding difficulties in timely and effective troubleshooting and obstruction during later maintenance and disassembly. This facilitates later maintenance and testing, improves the reliability of quick plugging and unplugging, and offers good applicability and ease of operation. Attached Figure Description

[0042] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0043] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0045] Existing corner connectors achieve electrical connections between devices by either a rear-entry plug-in method or a one-piece soldering method after overall mating. This approach has the following problems:
[0046] 1. The rear plug-in cable exit method is not conducive to the compact installation requirements between equipment. If the rear plug-in cable exit method is used, the equipment installation and operation space should be large to ensure that the cable is free and stress-free to meet the vibration and impact of the equipment.
[0047] II. Although the integrated welding method after overall insertion can meet the needs of equipment installation and operation in limited and narrow spaces, there are still difficulties. For example, the high temperature requirement of wave soldering limits the selection of materials for other components on the corner connector. Furthermore, after integrated welding, the stress changes caused by thermal shock and position tolerance of different materials may lead to defects such as poor welding, which cannot be checked in a timely and effective manner or hinders subsequent maintenance.
[0048] Third, both of the above methods require the positioning pins or soldered pins on the corner connector to be inserted into the circuit board for positioning, which both have problems with positioning and insertion / removal difficulties, making operation inconvenient.
[0049] Fourth, the integrated welding method after overall insertion makes it impossible to directly observe the internal connection status due to the obstruction of the encapsulation layer, and the encapsulation is an irreversible connection; the rear plug-in cable exit method uses an invisible crimping structure at the tail, and when problems such as cable detachment or poor disconnection occur, it is impossible to directly judge the state of the crimping point. The tail cable is usually tied and fixed with other components, and it needs to be untied when disassembling, which affects the layout of surrounding circuits; therefore, both of the above methods have the problems of not being able to troubleshoot in a timely and effective manner and hindering the disassembly and assembly of later maintenance.
[0050] like Figures 1-5 As shown, this embodiment provides an adapter connector 200, including a base 210 and a power female terminal 220. The base 210 includes a seat body 211 and a first protrusion 212 protruding from the seat body 211 along a first direction. The first protrusion 212 has a first cavity 2121, and the first cavity 2121 has an opening on the side opposite to the seat body 211. The power female terminal 220 passes through the seat body 211, with one end extending out of the seat body 211 for electrical connection with the circuit board 2000, and the other end being a first insertion hole 221 exposed in the first cavity 2121. Both the first insertion hole 221 and the first cavity 2121 are used for insertion into the corner socket 100.
[0051] One end of the power female terminal 220 is electrically connected to the circuit board 2000, and the first socket 221 at the other end is used to connect to the power male terminal 1121 on the corner socket 100, thereby realizing the electrical connection between the circuit board 2000 and the power male terminal 1121 on the corner socket 100 through the power female terminal 220; the first cavity 2121 is used to connect to the structural components on the corner socket 100, which can not only realize the mechanical structure fixation and resist vibration and impact, but also play a positioning and guiding role for the adapter connector 200 and the corner socket 100, which facilitates the connection and cooperation between the power female terminal 220 and the power male terminal 1121 on the adapter socket, achieving precise matching and convenient operation; and when the adapter connector 200 and the adapter socket are connected, the first protrusion 212 and the first cavity 2121 play a limiting role along the first direction. The adapter connector 200 is used for electrical and mechanical connection with the circuit board 2000 and the corner socket 100 on the device, respectively, realizing the connection between the circuit board 2000 and the corner socket 100.
[0052] The adapter connector 200 is pre-connected to the circuit board 2000. During use, the corner socket 100 and adapter connector 200 are plugged in, and the cable of another device is plugged into the adapter socket. Compared to the method of integrally plugging and then soldering, this solution avoids the impact of soldering on the corner socket 100 and the wiring harness on the adapter socket because the adapter connector 200 is pre-connected to the circuit board 2000. It also avoids the problem of poor solder joints caused by stress changes due to thermal shock and positional tolerances after soldering of the same material, which can lead to high resistance and current-cutting obstruction. Compared to the rear-plug-out method, this solution only requires the connection of the cable, corner socket 100, and adapter connector 200, avoiding precise matching with the circuit board 2000. This reduces the space required for equipment installation and is beneficial for compact installations between devices. The adapter connector 200 is soldered to the circuit board 2000 at one end and connected to the corner socket 100 by plugging in. This connection method and process are different from the overall plug-in and soldering method and the tail plug-out method. It is simpler to disassemble and assemble, easier to operate, and can adapt to smaller space requirements. It can realize quick installation and disassembly in the case of limited installation and operation space.
[0053] The first socket 221 and the first cavity 2121 are used to connect with the corner socket 100. They have good reliability and avoid the problems of not being able to troubleshoot in a timely and effective manner and being hindered in the later maintenance and disassembly. They facilitate later maintenance and testing, improve the reliability of quick plugging and unplugging, have good applicability, and are easy to operate.
[0054] The adapter connector 200 also includes a signal female terminal 230, which passes through the base 211. The base 211 also has a second protrusion 213, which has a second cavity 2131. The second cavity 2131 has an opening on the side away from the base 211. One end of the signal female terminal 230 extends out of the base 211 for connection with the circuit board 2000, and the other end is a second socket 231 exposed in the second cavity 2131. Both the second socket 231 and the second cavity 2131 are used to connect with the corner socket 100, so that the adapter connector 200 can simultaneously realize the connection of power and signal.
[0055] In one embodiment, the adapter connector 200 includes two power female terminals 220 and two signal female terminals 230. The two power female terminals 220 are arranged along a third direction, and the two signal female terminals 230 are located between the two power female terminals 220 and arranged along a second direction. Correspondingly, the base body 211 is provided with two first protrusions 212 having a first cavity 2121 and two second protrusions 213 having a second cavity 2131. The two first protrusions 212 are arranged along a third direction, and the two second protrusions 213 are located between the two first protrusions 212 and arranged along a second direction. The two power female terminals 220 and the two first protrusions 212 are correspondingly arranged, and the two signal female terminals 230 and the two second protrusions 213 are correspondingly arranged.
[0056] The circuit board 2000 has two first vias 2010 and two second vias 2040. Two power female terminals 220 pass through the two first vias 2010, exposing their soldering leads on the bottom surface of the circuit board 2000. Similarly, two signal female terminals 230 pass through the two second vias 2040, also exposing their soldering leads on the bottom surface of the circuit board 2000, thus achieving electrical connection between the adapter connector 200 and the circuit board 2000. Furthermore, the power female terminals 220, passing through the first vias 2010, and the signal female terminals 230, passing through the two second vias 2040, are spot-soldered on the back of the circuit board 2000, resulting in exposed solder joints. By visual inspection, using a magnifying glass, or even a multimeter probe, it is possible to directly observe whether there are problems such as cold solder joints, poor solder joints, or bridging. During maintenance, a desoldering pump can be used to remove the solder and disconnect the adapter connector 200 without damaging the circuit board 2000.
[0057] In one embodiment, the base 211 is provided with mounting slots, and the power female terminal 220 and the signal female terminal 230 are installed in their respective mounting slots to achieve assembly connection. The base 211 is provided with clamping arms 215 on both sides along the second direction. The clamping arms 215 clamp the power female terminal 220 on both sides to achieve stable installation, and the flanges 2151 at the ends of the clamping arms 215 are provided at the ends of the first sockets 221 to keep the power female terminal 220 at a preset height, thereby improving the installation accuracy along the first direction.
[0058] A guide rib 214 extends along a first direction on the outer side of the first protrusion 212 for alignment with the mounting panel 1000 on the device. For example, the mounting panel 1000 has an opening 1010. During installation, the first protrusion 212 passes through the opening 1010. If there is a slight angular or positional deviation between the two, the guide rib 214 will contact the inner wall of the opening 1010. Through mechanical force, the first protrusion 212 is corrected to the correct installation path, achieving centering of the adapter connector 200 relative to the mounting panel 1000. Furthermore, the end of the guide rib 214 has a chamfer. The guide rib 214 can be a protruding rib on the first protrusion 212 or a recessed groove on the first protrusion 212.
[0059] The base 211 has a positioning post 216 and / or elastic buckle 217 on the side opposite to the first protrusion 212. The circuit board 2000 has a positioning hole 2020. The positioning post 216 is inserted into the positioning hole 2020 to realize the positioning of the adapter connector 200 and the circuit board 2000. Specifically, the circuit board 2000 has a first through hole 2010 and a second through hole 2040 with the positioning post 216 as the reference to improve the connection accuracy and stability of the circuit board 2000 and the adapter connector 200. In addition, the first through hole 2010 and the second through hole 2040 are both provided with a diameter to absorb positional tolerances, so as to ensure that after mating, the power female terminal 220 and the first through hole 2010, the signal female terminal 230 and the second through hole 2040 are all centered in contact, which meets the design target requirements and avoids the problems of high product resistance and current blocking caused by stress changes due to positional difference.
[0060] The circuit board 2000 has a through hole 2030. The elastic buckle 217 can pass through the through hole 2030 and abut against the side of the circuit board 2000 away from the base 211. The elastic buckle 217 includes two elastic arms. The outer side of the elastic arms has a protrusion. In the initial state, the two elastic arms are separated from each other. During the connection between the circuit board 2000 and the adapter connector 200, the two elastic arms can come close to each other to pass through the through hole 2030. After that, the two elastic arms separate, and the protrusion abuts against the circuit board 2000 to prevent the elastic buckle 217 from passing through the through hole 2030 and causing it to detach. This ensures that the adapter connector 200 will not shake or fall off the circuit board 2000 during soldering and other processes.
[0061] A support platform 218 is provided on the side of the base 211 away from the first protrusion 212. The support platform 218 supports the circuit board 2000. There are four support platforms 218, located at the four corners of the base 210, so that the bottom of the base 210 and the circuit board 2000 are spaced apart to avoid contact between the two and possible interference with other electronic devices. At the same time, it helps air circulation and avoids the problem of concentrated heat generation.
[0062] The bottom of the seat 211 is provided with a seat plate, and the side opposite to the first protrusion 212 is provided with the aforementioned support platform 218, positioning post 216 and elastic buckle 217.
[0063] like Figures 6-9 As shown, this embodiment provides a corner socket 100, including a terminal module 110 and a shielding shell 120. The terminal module 110 includes an integrally connected insulating core 111 and a terminal 112. The insulating core 111 is bent and includes a first extension 1111 extending along a first direction and a second extension 1112 extending along a second direction. The first extension 1111 and the second extension 1112 are set at an angle greater than 0 and less than 180°. The shape of the terminal 112 is adapted to the shape of the insulating core 111. The terminal 112 passes through the insulating core 111, and both ends of the terminal 112 are exposed on the first extension 1111 and the second extension 1112 respectively. The shielding shell 120 is adapted to the shape of the insulating core 111 and includes a first half-shell 121 and a second half-shell 122. The first half-shell 121 and the second half-shell 122 are fastened and covered around the periphery of the insulating core 111 along a third direction, which is perpendicular to the first direction and the second direction respectively.
[0064] The insulating core 111 and terminal 112 are integrally connected, simplifying the structure. The first half-shell 121 and the second half-shell 122 are assembled components. The first half-shell 121 and the second half-shell 122 are assembled by snapping together from both sides of the insulating core 111 along a third direction. The assembly process is simple and does not require the development of molds for the integral molding of the shielding shell 120 and the terminal module 110, resulting in low cost. When the shielding shell 120 suffers partial damage, it can be replaced separately, facilitating maintenance. The first half-shell 121 and the second half-shell 122 form a complete shielding cavity, covering the periphery of the insulating core 111, meeting electromagnetic shielding requirements. Both the first half-shell 121 and the second half-shell 122 are used for conductive connections with both sides, improving fault tolerance.
[0065] Optionally, the terminal 112 and the insulating core 111 are both integral structures. The terminal 112 is formed by stamping, bending, and electroplating of a high-conductivity copper material, and has chamfered corners at both ends for interlocking guidance. The terminal 112 is inserted into a mold and integrally injection molded with the insulating core 111 to form an integral structure, which simplifies the number of parts and improves structural stability. One end of the insulating core 111 along the second direction is provided with a plug-in cavity 1114 corresponding to the wire harness end, and one end along the first direction is provided with a plug-in platform 1115 corresponding to the PCB end. The end of the first extension 1111 is provided with a plug-in platform 1115, and both the plug-in cavity 1114 and the plug-in platform 1115 are provided with guide corners.
[0066] Optionally, the shielding housing 120 is formed by stamping and bending of an alloy material and then electroplated.
[0067] The edges of the first half-shell 121 and the second half-shell 122 are joined together, ensuring that the first half-shell 121 and the second half-shell 122 completely cover the periphery of the insulating core 111, avoiding gaps. This prevents electromagnetic radiation generated internally from leaking through the shielding shell 120 and interfering with surrounding equipment; external electromagnetic signals also cannot penetrate the interior through the shielding shell 120, preventing noise in the high-voltage transmission signal. Furthermore, the edges of the first half-shell 121 and the second half-shell 122 are kept separate to avoid excessive structural thickness.
[0068] Both the first half-shell 121 and the second half-shell 122 are snapped into the insulating core 111. The insulating core 111 enables the first half-shell 121 and the second half-shell 122 to be engaged, ensuring a relatively stable installation. For example, both the first half-shell 121 and the second half-shell 122 are provided with snap-fit 123, and the insulating core 111 is provided with a slot 1113. The snap-fit 123 of the first half-shell 121 is correspondingly snapped into the corresponding slot 1113. The number and arrangement of the snap-fit 123 and slot 1113 between the two are not limited. Similarly, the snap-fit 123 of the second half-shell 122 is correspondingly snapped into the corresponding slot 1113. The number and arrangement of the snap-fit 123 and slot 1113 between the two are not limited.
[0069] The shielding housing 120 has a contact foot 124 at its end. The contact foot 124 is used to contact the external mounting panel 1000 to form electromagnetic shielding. The shielding housing 120 is connected to the mounting panel 1000 through the contact foot 124, thereby achieving effective electromagnetic shielding.
[0070] Multiple contact feet 124 are arranged at the end of the shielding housing 120, which increases the contact area between the contact feet 124 and the mounting panel 1000, provides a continuous and uniform conductive path, improves fault tolerance, reduces the gap between the two, and improves the electromagnetic shielding effect.
[0071] In one embodiment, the contact foot 124 includes a connecting piece 1241, which is bent and disposed on the outside of the shielding housing 120 for pressing contact with the surface of the mounting panel 1000. The contact foot 124 makes end-face contact with the mounting panel 1000 through the connecting piece 1241. A protrusion 1243 is provided on the side of the contact foot 124 facing the mounting panel 1000. The protrusion 1243 is connected to the mounting panel 1000, further increasing the tightness of the connection between the connecting piece 1241 and the mounting panel 1000.
[0072] In another embodiment, the mounting panel 1000 has an opening 1010, and the contact foot 124 includes a spring arm 1242. The spring arm 1242 extends along a first direction and is bent and disposed on the outside of the shielding housing 120 for abutting against the sidewall of the opening 1010. The contact foot 124 achieves radial contact with the sidewall of the opening 1010 through the spring arm 1242. Because the spring arm 1242 is elastic, the tightness and reliability of the connection with the sidewall of the latch 123 are improved.
[0073] In another embodiment, the contact foot 124 includes a connecting piece 1241 and a spring arm 1242. The connecting piece 1241 is bent and disposed on the outside of the shielding housing 120 for pressing contact with the surface of the mounting panel 1000. The spring arm 1242 extends along a first direction and is bent and disposed on the outside of the shielding housing 120 for abutting against the sidewall of the opening 1010 on the mounting panel 1000. By simultaneously providing the connecting piece 1241 and the spring arm 1242, the contact foot 124 can achieve both end-face contact with the mounting panel 1000 and radial contact with the opening 1010 of the mounting panel 1000. The specific arrangement of the contact foot 124 can be selected according to the actual application scenario and is not limited.
[0074] The corner socket 100 also includes a corner base 130 disposed on the outer periphery of the shielding housing 120. The assembly process of the corner socket 100 includes: connecting the insulating core 111 and the terminal 112 to form a terminal module 110; assembling the terminal module 110, the first half-shell 121 and the second half-shell 122 to form an assembly; placing the assembly in the forming mold of the corner base 130 for forming; one end of the corner base 130 is connected to the wire harness end, and the other end is connected to the device end. The device end is provided with a mounting panel 1000, and the corner base 130 is used to connect with the mounting panel 1000 to realize the corner socket 100 being stably installed on the mounting panel 1000.
[0075] In one embodiment, the corner bracket 130 has a flange 131 at one end along a first direction, and the flange 131 is connected to the mounting panel 1000. The end face of the flange 131 has a step, and the bottom surface 132 of the step has a positioning pin 133 and an annular waterproof ring 140 located inside the positioning pin 133. The annular waterproof ring 140 achieves a seal between the adapter socket and the mounting panel 1000, meeting dustproof, waterproof (e.g., IP67 rating) or airtightness requirements. The positioning pin 133 is used to engage with the positioning hole 1020 on the mounting panel 1000, improving the installation accuracy between the two. A contact foot 124 protrudes from the end face of the flange 131, connecting the contact foot 124 to the mounting panel 1000 during the process of fixing the corner bracket 130 to the mounting panel 1000. When the contact foot 124 is a connecting piece 1241, since the contact foot 124 protrudes from the end face of the flange 131, the connecting piece 1241 is pressed against the mounting panel 1000 during the connection between the corner seat 130 and the mounting panel 1000. When the contact foot 124 is a spring arm 1242, since the contact foot 124 extends along the first direction, the spring arm 1242 is inserted into the opening 1010 during the connection between the corner seat 130 and the mounting panel 1000. Optionally, the flange 131 is provided with a connecting hole 1311, which is bolted to the threaded hole 1030 of the mounting panel 1000. A collar is provided in the connecting hole 1311.
[0076] The corner bracket 130 has a contour ring 134 at one end along the second direction for connecting to the wire harness end, meeting waterproof requirements. The contour ring 134 also has a limiting function, which can reduce the relative wobbling between the corner bracket 130 and the wire harness end. The outer side of the contour ring 134 is provided with a foolproof protrusion 135 and a latch 136 for cooperating with the wire harness end to achieve foolproof installation and locking.
[0077] Optionally, the corner socket 100 has a bent structure with angles of 60°, 90°, 120°, 135°, 150°, etc., which can be set according to requirements. Correspondingly, the first direction and the second direction are set at an angle of 60°, 90°, 120°, 135°, 150°. The terminal 112, the shielding shell 120, and the corner base 130 are all bent. Specifically, the terminal 112 includes a first end extending along the first direction and a second end extending along the second direction. The first half-shell 121 includes a first shell portion extending along the first direction and a second shell portion extending along the second direction. The second half-shell 122 includes a portion extending along the first direction. The extended first housing portion and the extended second housing portion along the second direction, the first half-shell 121 and the second half-shell 122 can be symmetrically or asymmetrically arranged along the planes containing the first and second directions; the corner seat 130 includes a first seat body 211 extending along the first direction and a second seat body 211 extending along the second direction, the first extension portion 1111, the first end, the first housing portion and the first seat body 211 are correspondingly arranged, the second extension portion 1112, the second end, the second housing portion and the second seat body 211 are correspondingly arranged, the end of the first seat body 211 is provided with a flange 131, and the end of the second seat body 211 is provided with a contour ring 134. Multiple terminals 112 are provided, including a signal male terminal 1122 and a power male terminal 1121, an insulating core 111 is provided between the shielding housing 120 and the power male terminal 1121 and the signal male terminal 1122 to meet electrical clearance and positional requirements, which can be achieved by referring to existing technology.
[0078] In one embodiment, the corner socket 100 includes two power male terminals 1121 and two signal male terminals 1122. The two power male terminals 1121 are arranged along a third direction, and the two signal male terminals 1122 are located between the two power male terminals 1121. The two signal male terminals 1122 are arranged along a second direction. Correspondingly, the first extension 1111 is provided with four plug-in platforms 1115 at one end along the first direction. The two signal male terminals 1122 and the two power male terminals 1121 extend out of the four plug-in platforms 1115 respectively. The two plug-in platforms 1115 are inserted into the first cavity 2121 and the two plug-in platforms 1115 are inserted into the second cavity 2131.
[0079] like Figures 10-16 As shown, this embodiment also provides a corner connector 300, including a corner socket 100 and the aforementioned adapter connector 200. The corner socket 100 includes a terminal module 110, which includes an insulating core 111 and a power male terminal 1121 passing through the insulating core 111. The insulating core 111 is inserted into a first cavity 2121, and the power male terminal 1121 is inserted into a first socket 221.
[0080] The first socket 221 of the power female terminal 220 is plugged into the power male terminal 1121 on the corner socket 100 to achieve electrical connection; the first cavity 2121 is used to plug into the structural component, namely the plug-in platform 1115, on the corner socket 100 to achieve mechanical structure fixation. The adapter connector 200 is used for electrical and mechanical connection with the circuit board 2000 on the equipment and the corner socket 100 respectively, realizing the transfer between the circuit board 2000 and the corner socket 100. In use, the corner socket 100 and the adapter connector 200 are plugged in, and the cable of another device is plugged into the adapter socket. This requires less space for equipment installation and operation, is beneficial for compact installation between devices, simplifies disassembly and assembly, facilitates operation, and can adapt to smaller space requirements.
[0081] The corner socket 100 is detachably connected to the mounting panel 1000 of the device. The mounting panel 1000 has an opening 1010, through which a first protrusion 212 passes. A guide rib 214 extends along a first direction on the outer side of the first protrusion 212, and the guide rib 214 is used to align with the opening 1010. During installation, if there is a slight angular or positional deviation between the first protrusion 212 and the opening 1010, the guide rib 214 will contact the inner wall of the opening 1010. Through mechanical force, the first protrusion 212 is corrected to the correct installation path, achieving centering of the adapter connector 200 relative to the mounting panel 1000. The corner socket 100 is provided with a positioning pin 133, and the mounting panel 1000 has a positioning hole 1020. The positioning pin 133 is inserted into the positioning hole 1020, further ensuring the installation accuracy of the corner socket 100 and the mounting panel 1000. The corner socket 100 and the adapter connector 200 are respectively aligned and installed with the mounting panel 1000, thereby ensuring that the power male terminal 1121 of the corner socket 100 and the adapter connector 200 make correct contact with the first socket 221, the signal male terminal 1122 and the second socket 231, and that the current-cutting capacity is not affected by unstable resistance due to positional deviation.
[0082] The corner socket 100 also includes a shielding housing 120 covering the periphery of the insulating core 111. The shielding housing 120 has contact feet 124 at its ends, which contact with the mounting panel 1000 to form electromagnetic shielding. The contact feet 124 protrude from the end face of the flange 131, and during the process of fixing the corner socket 100 to the mounting panel 1000, the contact feet 124 are connected to the mounting panel 1000, thus achieving electromagnetic shielding.
[0083] The corner connector 300 can be a 2P or multi-pin connector, such as 3P, 4P, 5P, etc., without limitation.
[0084] Since the corner socket 100 has a bent structure with angles of 60°, 90°, 120°, 135°, 150°, etc., and the adapter connector 200 is connected to one end of the adapter socket along the first direction, the corner connector 300 can be a connector with angles of 60°, 90°, 120°, 135°, 150° or other degrees.
[0085] In one embodiment, the steps for connecting devices using the corner connector 300 include:
[0086] Step 1: Assemble the power female terminal 220 and signal female terminal 230 into the corresponding mounting slots of the base 211;
[0087] Step 2: The adapter connector 200 is positioned on the positioning hole 2020 of the circuit board 2000 by the positioning post 216, and is fastened by the elastic buckle 217 passing through the through hole 2030 to ensure the correct position of the adapter connector 200 and the circuit board 2000. Then, the power female terminal 220, the first through hole 2010, the signal female terminal 230 and the second through hole 2040 are completely soldered into the circuit board 2000.
[0088] Step 3: Place the circuit board 2000 and the adapter connector 200 in the equipment box 3000, and then install the mounting panel 1000 onto the equipment box 3000. The first protrusion 212 passes through the opening 1010 of the mounting panel 1000 and is guided by the guide rib 214 to be aligned with the position of the mounting panel 1000, effectively ensuring the relative position accuracy of the adapter connector 200 in the equipment.
[0089] Step 4: The plug-in platform 1115 of the corner socket 100 is plugged into the first cavity 2121 and the second cavity 2131 respectively. The power male terminal 1121 is plugged into the first socket 221 and the signal male terminal 1122 is plugged into the second socket 231. The insertion platform 1115 is inserted into the first cavity 2121 and the second cavity 2131 respectively, and plays a role in guiding the power male terminal 1121 and the signal male terminal 1122 to correct their positions. When installing the corner socket 100, it is necessary to ensure that the power male terminal 1121 does not contact the first socket 221 and the signal male terminal 1122 does not contact the second socket 231. That is, the insertion depth of the insertion platform 1115 and the first cavity 2121 is greater than the insertion depth of the power male terminal 1121 and the first socket 221. The position of the insertion platform 1115 controls the correct contact between the power male terminal 1121 and the first socket 221, the signal male terminal 1122 and the second socket 231, and prevents the current cutting capacity from being unstable due to damage caused by position deviation.
[0090] Step 5: After the corner socket 100 and the corner connector 300 are connected, the bolts are passed through the connection hole 1311 on the flange 131 to connect with the threaded hole 1030 on the mounting panel 1000 for fixed installation.
[0091] After the corner socket 100 is installed on the equipment, it facilitates later maintenance and inspection, and improves the reliability of quick plugging and unplugging.
