Description

Technical Field

[0001] This utility model relates to the field of connector technology, and specifically to a high-voltage connector assembly with an injection-molded structure. Background Technology

[0002] Currently, connectors are used more widely in the medical field, and the demand for high-voltage, low-current signal transmission in imaging and ultrasound transmission fields has increased significantly, which has led to increasingly higher demands and performance requirements for miniaturized, high-voltage-resistant multi-core connectors.

[0003] The existing high-voltage connectors work by increasing the size of the insulator to increase the spacing between adjacent pins / sockets, thereby increasing the creepage distance and air gap, and thus improving high-voltage withstand performance. However, this design has the following drawbacks: 1. The connector is large and heavy, making it inconvenient for users to operate; 2. The large size results in higher raw material and processing costs; 3. The high-voltage withstand performance is not satisfactory. The air withstand voltage is approximately 3kV / mm. Therefore, to achieve 5kV withstand voltage, the spacing between any two pins must be greater than 2mm due to manufacturing tolerances. Adding the outer diameter of each pin / socket, for example, a 26-pin connector requires an insulator outer diameter of at least 26.8mm and a connector assembly outer diameter of approximately 38.5mm. An outer diameter approaching 4cm is already considered very large in the medical field. For 12kV withstand voltage, the connector assembly outer diameter needs to be even larger, approximately 54.5mm. This results in a very large connector size. Utility Model Content

The plug assembly includes a plug color ring, a plug outer sleeve, a plug inner sleeve, a plug pin assembly, a plug pin seat, a plug wire clamp, and a plug tail cap. The plug color ring, the plug outer sleeve, the plug inner sleeve, the plug pin assembly, the plug pin seat, the plug wire clamp, and the plug tail cap are coaxially assembled together in sequence along the axial direction, and the plug pin assembly is welded to the plug pin seat and placed inside the plug inner sleeve. The socket assembly includes a socket slotted nut, a socket housing, a socket socket piece, a socket socket seat, and a socket nut. The socket slotted nut, the socket housing, the socket socket piece, the socket socket seat, and the socket nut are coaxially assembled together in sequence along the axial direction. The socket socket piece and the socket socket seat are welded together and placed inside the socket housing. The ends of the plug pin and the socket hole are respectively the plug insertion end and the socket insertion hole, and the plug assembly and the socket assembly are assembled together by inserting the plug insertion end into the socket insertion hole.

[0006] Preferably, the plug pin assembly has a front reduction section near the plug insertion end of the socket assembly. The front reduction section accommodates a front pressure-resistant injection molded body by embedded injection molding. After the plug pin assembly is assembled with the plug pin seat, the front pressure-resistant injection molded body wraps around the plug insertion end of the plug pin assembly, while both ends extend into the interior of the plug pin seat and extend out of the exterior of the plug pin seat, respectively.

[0007] Preferably, the plug pin assembly has a rear diameter reduction section at a position away from the plug solder cup end of the socket assembly. The rear diameter reduction section accommodates a rear pressure-resistant injection molded body by means of embedded injection molding. After the plug pin assembly is assembled with the plug pin seat, the rear pressure-resistant injection molded body wraps around the plug solder cup end of the plug pin assembly, while both ends extend into the interior of the plug pin seat and extend out of the exterior of the plug pin seat, respectively.

[0008] Preferably, the socket socket component has a socket reduction section at the socket welding cup end near the socket assembly. The socket reduction section accommodates the socket pressure-resistant injection molded body by embedded injection molding. After the socket socket component is assembled with the socket hole seat, the socket pressure-resistant injection molded body wraps around the socket welding cup end of the socket socket component, while both ends extend into the socket hole seat and extend out of the socket hole seat, respectively.

[0009] Preferably, the insulation path after the plug assembly and the socket assembly are mated together is as follows: the rear pressure-resistant injection molded body of the plug - the plug pin seat - the front pressure-resistant injection molded body of the plug - the socket hole seat - the socket pressure-resistant injection molded body.

[0010] Preferably, the plug insertion end of the plug pin is extended and longer than the depth of the socket insertion hole of the socket socket.

[0011] Preferably, the plug pin is provided with a clamping and fixing part at the middle position.

[0012] Preferably, the materials used for the front pressure-resistant injection molded body of the plug include pure materials of PEEK (polyether ether ketone), PI (polyimide), PEI (polyether imide), and PPS (polyphenylene sulfide) and mixtures thereof as the main materials.

[0013] Preferably, the materials used for the pressure-resistant injection molded body of the plug include pure materials of PEEK (polyether ether ketone), PI (polyimide), PEI (polyether imide), and PPS (polyphenylene sulfide) and mixtures thereof as the main materials.

[0015] In the high-voltage connector assembly employing the above-mentioned injection-molded structure, in practical design, the plug pin assembly firstly has a front reduction section near the plug insertion end of the socket assembly. This front reduction section accommodates the front pressure-resistant injection molded body via embedded injection molding. After the plug pin assembly is assembled with the plug pin seat, the front pressure-resistant injection molded body encloses the plug insertion end of the plug pin assembly, with both ends extending into the plug pin seat and extending outwards from the plug pin seat, respectively. This allows the front pressure-resistant injection molded body to provide good insulation protection for the portion of the plug pin assembly extending outwards from the plug pin seat, increasing creepage distance and voltage withstand performance. Simultaneously, the plug pin assembly, away from the socket assembly... The plug assembly has a reduced diameter section at the plug solder cup end. This reduced diameter section houses the rear pressure-resistant injection molded body via embedded injection molding. After the plug pin and the plug pin seat are assembled, the rear pressure-resistant injection molded body encloses the plug solder cup end of the plug pin, with both ends extending into and out of the plug pin seat. This provides good insulation protection for the portion of the plug pin extending out of the plug pin seat, increasing creepage distance and withstand voltage performance. Furthermore, the socket socket has a reduced diameter section near the socket solder cup end of the socket assembly, which is also constructed via embedded injection molding. The socket includes a pressure-resistant injection molded body. After the socket socket and socket base are assembled, the pressure-resistant injection molded body encloses the socket welding cup end of the socket socket while extending into the socket base and out of the socket base at both ends. This allows the pressure-resistant injection molded body to provide good insulation protection for the portion of the socket socket extending out of the socket base, increasing creepage distance and voltage withstand performance. Furthermore, because the plug insertion end of the plug pin is extended and longer than the depth of the socket insertion hole of the socket socket, after the plug assembly and socket assembly are mated together, the plug insertion end of the plug pin can penetrate deeply into the socket insertion hole of the socket socket. The plug pin assembly's plug insertion end exposes a portion of the socket insertion hole of the socket assembly. This sufficient insertion length effectively prevents insertion failure / signal transmission disruption caused by vibration or other factors during use. Simultaneously, the socket pressure-resistant injection molded body extends deep into the socket socket of the socket assembly, providing sufficient length on both sides of the socket socket's end face, thus providing insulation, increasing creepage distance, and enhancing voltage withstand performance. Furthermore, after the plug assembly and socket assembly are assembled, an insulating path is formed: rear pressure-resistant injection molded body of the plug - plug pin socket - front pressure-resistant injection molded body of the plug - socket socket - socket pressure-resistant injection molded body.The creepage distance can be significantly increased, thereby enhancing the product's voltage withstand performance. Simultaneously, the clamping and fixing part is located at the center of the plug pin assembly. This clamping and fixing part allows for stable clamping and fixing of the plug pin assembly during injection molding, preventing deformation and defects caused by the impact of the injection molding material. Furthermore, the injection molding process improves the consistency between the plug pin assembly and the socket, making assembly easier. The compact structure reduces the outer diameter of the connector structure formed by the plug and socket assemblies, while achieving a high voltage withstand level. This makes it suitable for more fields and easier for users to operate. Moreover, the front and rear pressure-resistant injection molded bodies of the plug and socket are available in various materials, facilitating operation for production personnel and adapting to various usage environments.

[0016] The beneficial effects are as follows: 1. The plug pin assembly of this utility model has a front reduction section at the plug insertion end near the socket assembly. The front reduction section accommodates the front pressure-resistant injection molded body of the plug by the embedded part injection molding method. After the plug pin assembly is assembled with the plug pin seat, the front pressure-resistant injection molded body of the plug encloses the plug insertion end of the plug pin assembly, and at the same time, both ends extend into the inside of the plug pin seat and extend out of the plug pin seat respectively. In this way, the front pressure-resistant injection molded body of the plug can provide good insulation protection for the part of the plug pin assembly that extends out of the plug pin seat, increase the creepage distance, and increase the voltage withstand performance. 2. The plug pin assembly has a rear diameter reduction section at the plug solder cup end away from the socket assembly. The rear diameter reduction section accommodates the rear pressure-resistant injection molded body of the plug through embedded injection molding. After the plug pin assembly is assembled with the plug pin seat, the rear pressure-resistant injection molded body of the plug encloses the plug solder cup end of the plug pin assembly, and its two ends extend into the plug pin seat and extend out of the plug pin seat respectively. In this way, the rear pressure-resistant injection molded body of the plug can provide good insulation protection for the part of the plug pin assembly that extends out of the plug pin seat, increase the creepage distance, and increase the withstand voltage performance. 3. The socket socket is provided with a socket reduction section at the socket welding cup end near the socket assembly. The socket reduction section accommodates the socket pressure-resistant injection body by embedded injection molding. After the socket socket is assembled with the socket socket seat, the socket pressure-resistant injection body wraps around the socket welding cup end of the socket socket and extends into the socket seat and out of the socket seat at both ends, respectively. In this way, the socket pressure-resistant injection body can provide good insulation protection for the part of the socket socket that extends out of the socket seat, increase the creepage distance, and increase the voltage withstand performance. 4. The plug pin of the plug is extended and longer than the socket hole of the socket assembly. This allows the plug pin to penetrate deep into the socket hole of the socket assembly after the plug and socket assemblies are assembled. A portion of the plug pin will protrude from the socket hole. This sufficient insertion length effectively prevents misalignment / signal transmission failure caused by vibration or other factors during use. At the same time, the socket pressure-resistant injection body is inserted into the socket socket of the socket assembly. Sufficient length is provided on both sides of the socket socket end face of the socket assembly, which provides insulation, increases creepage distance, and enhances voltage resistance. 5. After the plug assembly and socket assembly are assembled together, an insulation path is formed, which is: the rear pressure-resistant injection molded body of the plug - the plug pin seat - the front pressure-resistant injection molded body of the plug - the socket hole seat - the socket pressure-resistant injection molded body. The creepage distance can be greatly increased, thereby increasing the voltage resistance performance of the product. 6. A clamping and fixing part is provided in the middle of the plug and pin part. The clamping and fixing part can be used to stably clamp and fix the plug and pin part during the injection molding of the embedded part, so as to avoid deformation of the plug and pin part due to the impact of the injection plastic and the resulting defects. 7. The embedded injection molding process improves the consistency of the plug pins and sockets, making them easier to assemble. At the same time, the structure is compact, reducing the outer diameter of the connector structure formed by the plug and socket assembly. It also achieves a high voltage resistance, making it suitable for more fields and easier for users to operate. 8. The front pressure-resistant injection molded body of the plug, the rear pressure-resistant injection molded body of the plug, and the pressure-resistant injection molded body of the socket are all available in a variety of materials, which makes it easier for production personnel to operate and can also accommodate a variety of usage environments.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] See Figures 1-3 As shown, this utility model provides a high-voltage connector assembly with an injection-molded structure, including a plug assembly 1 and a socket assembly 2. The plug assembly 1 includes a plug color ring 101, a plug outer sleeve 102, a plug inner sleeve 103, a plug pin 104, a plug pin seat 105, a plug wire clamp 106, and a plug tail cap 107. The plug color ring 101, plug outer sleeve 102, plug inner sleeve 103, plug pin 104, plug pin seat 105, plug wire clamp 106, and plug tail cap 107 are coaxially assembled together in sequence along the axial direction, and the plug pin 104 and the plug pin seat 105 are welded and assembled side by side. Inside the plug inner sleeve 103, the socket assembly 2 includes a socket slotted nut 201, a socket housing 202, a socket socket piece 203, a socket hole seat 204, and a socket nut 205. The socket slotted nut 201, socket housing 202, socket socket piece 203, socket hole seat 204, and socket nut 205 are coaxially assembled together in sequence along the axial direction. The socket socket piece 203 and the socket hole seat 204 are welded together and placed inside the socket housing 202. The purpose of this arrangement is to facilitate the use of the plug assembly 1 and the socket assembly 2 to form a connector structure for use.

[0022] See Figures 1-5As shown, the ends of the plug pin 104 and the socket 203 that are close to each other are the plug insertion end 1041 and the socket insertion hole 2031, respectively. The plug assembly 1 and the socket assembly 2 are assembled together by inserting the plug insertion end 1041 into the socket insertion hole 2031. The advantage of this arrangement is that it forms a path through the plug insertion end 1041 and the socket insertion end to realize signal transmission. At the same time, the plug insertion end 1041 of the plug pin 104 is extended and longer than the depth of the socket insertion hole 2031 of the socket 203. With this arrangement, the sufficient insertion length of the plug pin 104 can effectively prevent insertion failure / signal transmission failure caused by factors such as vibration during use.

[0023] See Figures 1-5 As shown, the following optimizations have been made to this application. Specifically, the plug pin assembly 104 has a front reduction section 1042 near the plug insertion end 1041 of the socket assembly 2. The front reduction section 1042 accommodates the front pressure-resistant injection molded body 1043 of the plug by embedded injection molding. After the plug pin assembly 104 is assembled with the plug pin seat 105, the front pressure-resistant injection molded body 1043 wraps around the plug insertion end 1041 of the plug pin assembly 104, while both ends extend into the interior of the plug pin seat 105 and extend out of the plug pin seat 105, respectively. This allows the front pressure-resistant injection molded body 1043 to provide good insulation protection for the part of the plug pin assembly 104 that extends out of the plug pin seat 105, increasing the creepage distance and improving the withstand voltage performance. Optionally, the plug pin assembly 104 may have a rear diameter reduction section 1046 located at the plug solder cup end 1047 away from the socket assembly 2. The rear diameter reduction section 1046 accommodates the rear pressure-resistant injection molded body 1045 of the plug through an embedded injection molding process. After the plug pin assembly 104 is assembled with the plug pin seat 105, the rear pressure-resistant injection molded body 1045 encloses the plug solder cup end 1047 of the plug pin assembly 104, while both ends extend into the interior of the plug pin seat 105 and extend out of the plug pin seat 105, respectively. This allows the rear pressure-resistant injection molded body 1045 to provide good insulation protection for the part of the plug pin assembly 104 that extends out of the plug pin seat 105, thereby increasing the creepage distance and improving the withstand voltage performance. Optionally, the socket socket 203 has a socket reduction section 2032 near the socket solder cup end 2034 of the socket assembly 2. The socket reduction section 2032 accommodates the socket pressure-resistant injection molded body 2033 by embedded injection molding. After the socket socket 203 is assembled with the socket seat 204, the socket pressure-resistant injection molded body 2033 covers the socket solder cup end 2034 of the socket socket 203, while both ends extend into the socket seat 204 and out of the socket seat 204, respectively. This allows the socket pressure-resistant injection molded body 2033 to provide good insulation protection for the part of the socket socket 203 that extends out of the socket seat 204, increasing the creepage distance and improving the voltage withstand performance.

[0024] See Figures 1-5 As shown, the insulation path after the plug assembly 1 and socket assembly 2 are assembled together is as follows: plug rear pressure-resistant injection molding body 1045 - plug pin seat 105 - plug front pressure-resistant injection molding body 1043 - socket hole seat 204 - socket pressure-resistant injection molding body 2033. This configuration significantly increases the creepage distance, thereby enhancing the product's voltage withstand performance, making it suitable for more fields and easier for users to operate. Optionally, a clamping and fixing part 1044 can be provided in the middle of the plug pin component 104. This clamping and fixing part 1044 can stably clamp and fix the plug pin component 104 during injection molding, preventing deformation and defects caused by the impact of the injection molding material.

[0025] See Figures 1-5 As shown, the materials used for the front pressure-resistant injection molded body 1043 of the plug include pure materials of PEEK (polyetheretherketone), PI (polyimide), PEI (polyetherimide), and PPS (polyphenylene sulfide), as well as mixtures with these as the main materials. The materials used for the rear pressure-resistant injection molded body 1045 of the plug include pure materials of PEEK (polyetheretherketone), PI (polyimide), PEI (polyetherimide), and PPS (polyphenylene sulfide), as well as mixtures with these as the main materials. The materials used for the socket pressure-resistant injection molded body 2033 of the socket include pure materials of PEEK (polyetheretherketone), PI (polyimide), PEI (polyetherimide), and PPS (polyphenylene sulfide), as well as mixtures with these as the main materials. This arrangement is because the front pressure-resistant injection molded body 1043, the rear pressure-resistant injection molded body 1045, and the socket pressure-resistant injection molded body 2033 all have multiple material options, which makes it easier for production personnel to operate and can accommodate various usage environments.

[0026] Using the above structure, in actual design, the plug pin assembly 104 firstly has a front reduction section 1042 near the plug insertion end 1041 of the socket assembly 2. The front reduction section 1042 accommodates the front pressure-resistant injection molded body 1043 of the plug through embedded injection molding. After the plug pin assembly 104 is assembled with the plug pin seat 105, the front pressure-resistant injection molded body 1043 of the plug pin assembly 104 covers the plug insertion end 1041 of the plug pin assembly 104, while both ends extend into the interior of the plug pin seat 105 and extend out of the plug pin seat 105, respectively. In this way, the front pressure-resistant injection molded body 1043 of the plug pin assembly 104 can provide good insulation protection for the part of the plug pin assembly 104 that extends out of the plug pin seat 105, increase the creepage distance, and increase the withstand voltage performance. At the same time, the plug... The pin assembly 104 has a reduced diameter section 1046 at a position away from the plug solder cup end 1047 of the socket assembly 2. The reduced diameter section 1046 accommodates a pressure-resistant injection molded body 1045 at the rear of the plug via embedded injection molding. After the pin assembly 104 is assembled with the plug pin seat 105, the pressure-resistant injection molded body 1045 covers the plug solder cup end 1047 of the pin assembly 104, while its two ends extend into the plug pin seat 105 and out of the plug pin seat 105, respectively. This allows the pressure-resistant injection molded body 1045 to provide good insulation protection for the part of the pin assembly 104 that extends out of the plug pin seat 105, increasing the creepage distance and voltage withstand performance. Furthermore, the socket socket 203 is located near the socket assembly 2. The socket welding cup end 2034 is provided with a socket reduction section 2032. The socket reduction section 2032 accommodates the socket pressure-resistant injection molded body 2033 through embedded injection molding. After the socket socket 203 is assembled with the socket socket seat 204, the socket pressure-resistant injection molded body 2033 covers the socket welding cup end 2034 of the socket socket 203, while both ends extend into the socket socket seat 204 and extend out of the socket socket seat 204, respectively. In this way, the socket pressure-resistant injection molded body 2033 can provide good insulation protection for the part of the socket socket 203 that extends out of the socket socket seat 204, increase the creepage distance, and increase the withstand voltage performance. Furthermore, because the plug insertion end 1041 of the plug pin 104 is extended and longer than the socket insertion hole 203 of the socket socket 203, the socket insertion end 2033 is also extended. The plug is 31mm deep, ensuring that after the plug assembly 1 and socket assembly 2 are assembled, the plug pin 1041 can penetrate deep into the socket socket 2031 of the socket 203, with a portion of the plug pin 1041 protruding from the socket socket 2031. This sufficient insertion length of the plug pin 104 effectively prevents misalignment / signal transmission failure due to vibration or other factors during use. Simultaneously, the socket pressure-resistant injection molded body 2033 extends deep into the socket base 204 of the socket assembly 2, providing sufficient length on both sides of the socket base 204, thus providing insulation, increasing creepage distance, and enhancing voltage withstand performance.Furthermore, after the plug assembly 1 and socket assembly 2 are assembled together, an insulation path is formed: plug rear pressure-resistant injection molded body 1045 - plug pin seat 105 - plug front pressure-resistant injection molded body 1043 - socket hole seat 204 - socket pressure-resistant injection molded body 2033. This significantly increases the creepage distance, thereby enhancing the product's voltage withstand performance. Simultaneously, a clamping and fixing part 1044 is provided in the middle of the plug pin component 104. This clamping and fixing part 1044 allows for stable clamping and fixing of the plug pin component 104 during injection molding, preventing the plug pin component 104 from being impacted by the injection molding material. The impact-induced deformation and defects, coupled with the improved consistency of the plug pin 104 and socket socket 203 through the embedded injection molding process, make assembly easier. The compact structure reduces the outer diameter of the connector structure formed by the mating assembly of the plug assembly 1 and socket assembly 2, while achieving a high voltage withstand rating. This makes it suitable for more fields and easier for users to operate. Furthermore, the plug front pressure-resistant injection molded body 1043, the plug rear pressure-resistant injection molded body 1045, and the socket pressure-resistant injection molded body 2033 are available in various materials, facilitating operation for production personnel and adapting to various usage environments.
