Description

Technical Field

[0001] This utility model relates to the field of connection devices, specifically to a device-end socket, an adapter socket, and a printed circuit board connector socket. Background Technology

[0002] Driven by technological advancements, the new energy vehicle market has seen continuous growth in production and sales, with an increasing market share. Connectors and sockets are commonly used power connection components in automobiles. Existing connectors and sockets typically include a device-side socket and an adapter socket. One end of the adapter socket connects to the PCB board, and the other end connects to the power terminal of the device-side socket, thus enabling circuit continuity. For example, Chinese utility model patent CN213184880U discloses an on-board adapter connector system. This system includes a first connector (i.e., the device-side socket) and a second connector (i.e., the adapter socket). The power terminal of the first connector is housed within a cylindrical insulating body, while the adapter terminal of the second connector is located in a contact mounting hole. Thus, when the device-side socket and the adapter socket are engaged, the insertion portion of the power terminal and the adapter terminal is located within the cylindrical insulating body, preventing heat dissipation from the power terminal and potentially causing overheating of the connector.

[0003] Chinese utility model patent CN219833102U discloses a high-voltage connector assembly. This assembly includes a board-end assembly (i.e., a device-end socket) and an adapter assembly (i.e., an adapter socket). The power terminals of the board-end assembly pass through the mounting panel of the housing, and their mating portions for engaging with the adapter terminals of the adapter assembly are exposed. The housing of the adapter assembly has a semi-enclosed structure. This design facilitates heat dissipation when the power terminals of the board-end assembly engage with the adapter terminals of the adapter assembly, preventing overheating of the connector socket. However, vibrations or impacts generated during vehicle operation can cause mutual movement between the power terminals and the adapter terminals. In this case, the power terminals and adapter terminals directly bear all the impact force, which can easily lead to terminal deformation, compromising reliable contact and affecting normal use. Utility Model Content

[0004] The purpose of this invention is to provide a device-side socket to solve the problem that existing connector sockets, while ensuring heat dissipation, cause the power terminals and adapter terminals to directly bear all the impact forces, making them prone to deformation under impact or vibration. The invention also aims to provide an adapter socket to solve the problem that existing connector sockets, while ensuring heat dissipation, cause the power terminals and adapter terminals to directly bear all the impact forces, making them prone to deformation under impact or vibration. Furthermore, this invention aims to provide a printed circuit board connector socket to solve the problem that existing connector sockets, while ensuring heat dissipation, cause the power terminals and adapter terminals to directly bear all the impact forces, making them prone to deformation under impact or vibration.

[0005] The present invention provides a device-end socket comprising a socket housing and a power terminal disposed within the socket housing. The socket housing is provided with a connecting flange for connecting to a fixed panel. The power terminal protrudes rearward from the rear end of the connecting flange to form a mating end for mating with the adapter terminal of the adapter socket. The socket housing is also provided with a constraint arm protruding rearward from the connecting flange for mating with a constraint cavity on the adapter socket, or a constraint cavity for mating with a constraint arm on the adapter socket. The device-end socket and the adapter socket are constrained in the up-down and left-right directions by the mating of the constraint arm and the constraint cavity.

[0006] Furthermore, the constraint arms are located on the socket housing and are arranged in groups. Some groups of constraint arms are used to constrain the corresponding constraint cavity in the vertical direction, while other groups of constraint arms are used to constrain the corresponding constraint cavity in the horizontal direction.

[0007] Furthermore, the power terminals are arranged in pairs, and the constraint arm includes a guide post extending to the front end of the pair of power terminals. During the insertion process, the insertion time of the guide post and the corresponding constraint cavity is earlier than the insertion time of the power terminal and the adapter terminal.

[0008] Furthermore, the guide post is positioned between two pairs of power terminals.

[0009] Furthermore, there are two pairs of power terminals, and one pair protrudes backward from the connecting flange by a greater length than the other pair protruding backward from the connecting flange.

[0010] Furthermore, the protruding section of the longer power terminal located in front of the mating end is wrapped by a wrapping section integral with the socket housing.

The mating time of the anti-deviation rib and the anti-deviation groove is earlier than the mating time of the power terminal and the adapter terminal.

[0011] Furthermore, the two pairs of power terminals are arranged side by side, and the two pairs of power terminals are arranged vertically, with anti-deviation ribs located on the left and right sides of the corresponding power terminals.

The engagement of the constraint arm and the constraint cavity constrains the device-end socket and the adapter socket in the up-down and left-right directions. Thus, even if the vehicle body vibrates or is impacted, the mutual engagement of the constraint arm and the constraint cavity restricts the relative movement of the adapter socket and the device-end socket, while also providing load-bearing capacity between them. This prevents significant impacts on the power terminals and the adapter terminals, avoids large deformations, ensures the reliability of their mating, and extends the service life of the printed circuit board connector socket.

[0016] Furthermore, the constraint cavities are located on the adapter housing and are arranged in groups. Some groups of constraint cavities are used to constrain the corresponding constraint arms in the vertical direction, while other groups of constraint cavities are used to constrain the corresponding constraint arms in the horizontal direction.

[0017] Furthermore, the adapter terminals are arranged in pairs, and the constraint cavity includes a guide groove located between the two paired adapter terminals.

[0018] Furthermore, the adapter terminal is a 90° bent-off terminal, and the end used to connect with the printed circuit board extends upward out of the adapter housing. The adapter end extends forward, and the lower side of the adapter housing is open, with the open portion corresponding vertically to the mounting cavity used to install the adapter terminal. The guide groove opens downward.

[0019] Furthermore, there are two pairs of adapter terminals, and the adapter ends of the two pairs of adapter terminals are arranged one in front of the other, with the adapter end of the adapter terminal on the rear side being lower than the adapter end of the adapter terminal on the front side.

[0020] Furthermore, the adapter housing has a wrapping section cavity on the front side of the adapter terminal with the adapter end on the rear side, into which the wrapping section of the socket housing is inserted. The cavity wall of the wrapping section cavity has an anti-deviation groove for cooperating with the anti-deviation protrusion on the device end socket.

[0021] Furthermore, the two pairs of adapter terminals are arranged side by side, and the two pairs of adapter terminals are arranged vertically.

The engagement of the constraint arm and constraint cavity constrains the device-side socket and the adapter socket in the up-down and left-right directions. Thus, even if the vehicle body vibrates or is impacted, the mutual engagement of the constraint arm and constraint cavity restricts the relative movement of the adapter socket and the device-side socket, while also providing load-bearing capacity between them. This prevents significant impacts on the power terminals and the adapter terminals, avoids large deformations, ensures the reliability of their mating, and extends the service life of the printed circuit board connector socket.

[0023] Another aspect of this utility model provides a printed circuit board connector socket, which includes a device-end socket and an adapter socket. The device-end socket includes a socket housing and a power terminal disposed within the socket housing. The socket housing has a connecting flange for connecting to a fixed panel. The power terminal protrudes rearward from the rear end of the connecting flange to form a mating end for mating with the adapter terminal of the adapter socket.

One end of the adapter terminal is for connecting to the printed circuit board, and the other end is an adapter end for mating with the mating end of the power terminal. The socket housing also has a constraint arm protruding rearward from the connecting flange. The adapter housing has a constraint cavity that mates with the constraint arm on the device-end socket; or the socket housing has a constraint cavity, and the adapter housing has a forward-protruding constraint arm that mates with the constraint cavity on the device-end socket. The device-end socket and the adapter socket are constrained in the up-down and left-right directions by the cooperation of the constraint arm and the constraint cavity.

[0024] Furthermore, the constraint arms are located on the socket housing and are arranged in groups, and the constraint cavities are located on the adapter housing and are arranged in groups.

[0043] This utility model proposes an improved technical solution to address the problems existing in the above-mentioned technical solutions: A constraint arm protruding rearward from the connecting flange is provided on the socket housing for engaging with a constraint cavity on the adapter socket, or a constraint cavity engaging with a constraint arm on the adapter socket. The engagement of the constraint arm and the constraint cavity constrains the device-end socket and the adapter socket in the up-down and left-right directions. Thus, even if the vehicle body vibrates or is impacted, the mutual engagement of the constraint arm and the constraint cavity restricts the relative movement of the adapter socket and the device-end socket, while also providing load-bearing capacity between them. This prevents significant impacts on the power terminals and the adapter terminals, avoids large deformations, ensures the reliability of their mating, and extends the service life of the printed circuit board connector socket.

[0044] Based on the above concept, the present invention provides a printed circuit board connector socket including as follows: Figure 7 , Figure 8 The device-side socket 1 and adapter socket 2 are shown. The device-side socket 1 includes, as follows: Figure 1 The socket housing 110 shown includes a power terminal 101 disposed within the socket housing 110. In this embodiment, the socket housing 110 is integrally injection molded, and the power terminal 101 is injection molded within the socket housing 110. A fixed panel 4 is provided on the vehicle body. The fixed panel 4 has clearance holes for the power terminal 101 and insulator at the rear end of the socket housing 110 to pass through. The socket housing 110 has a connecting flange 108 for connecting to the fixed panel 4. The power terminal 101 protrudes rearward from the rear end of the connecting flange 108 to form a mating end for mating with the adapter terminal 201 of the adapter socket 2, and the mating end is exposed. The socket housing 110 also has a constraint arm protruding rearward from the connecting flange 108. The adapter socket 2 includes, as shown in the figure... Figure 3 , Figure 4 , Figure 5The adapter housing 21 shown has an adapter terminal mounting cavity inside. An adapter terminal 201 is installed in the adapter terminal mounting cavity. One end of the adapter terminal 201 is used to connect to the printed circuit board 3, this end is called the connection end 207, and the other end is an adapter end 206 for mating with the mating end of the power terminal 101. The adapter housing 21 has a constraint cavity for cooperating with the constraint arm on the device end socket 1. The device end socket 1 and the adapter socket 2 are constrained in the up, down, left, and right directions through the cooperation of the constraint arm and the constraint cavity. Thus, even if the vehicle body vibrates or is impacted, the relative movement of the adapter socket 2 and the device end socket 1 can be limited through the mutual cooperation of the constraint arm on the socket housing 110 and the constraint cavity on the adapter housing 21. At the same time, it acts as a load-bearing element between the adapter socket 2 and the device end socket 1, avoiding large impacts on the power terminal 101 and the adapter terminal 201, preventing large deformation of both, ensuring the reliability of their mating, and extending the service life of the printed circuit board connector socket.

[0045] In another embodiment, the socket housing 110 is provided with a constraint cavity, and the adapter housing 2 is provided with a forward-protruding constraint arm for engaging with the constraint cavity on the socket housing 110. It is sufficient to ensure that the relative movement of the adapter socket 2 and the device end socket 1 can be restricted through the mutual engagement of the constraint arm and the constraint cavity.

[0046] like Figure 2 As shown, the outer side (front side) of the connecting flange 108 of the socket housing 110 has a forward-extending cylindrical insertion cavity. The insertion cavity contains a forward-protruding insulating insertion portion, within which a terminal cavity is provided. A power terminal 101 extends into the terminal cavity. An annular space is formed between the insulating insertion portion and the inner wall of the cylindrical insertion cavity to allow the mating section of the adapter plug to be inserted. The outer surface of the insulating insertion portion is fitted with... Figure 2 The shield 111 shown has its rear end abutting against the wall of the clearance hole of the fixed panel 4 via an abutment spring. In order to achieve a seal with the fixed panel 4, a sealing ring 109 is also provided on the rear side of the socket housing 110.

[0047] In this embodiment, the socket housing 110 is integrally injection molded, and the power terminal 101 is injection molded inside the socket housing. In other embodiments, the socket housing may include an outer shell and a socket insulator installed inside the outer shell. The outer shell includes a connecting flange and a cylindrical insertion cavity. The power terminal is injection molded inside the socket insulator, and the socket insulator is fixedly installed inside the outer shell.

[0048] In this embodiment, the constraint arms are located on the socket housing 110 and arranged in groups, while the constraint cavities are located on the adapter housing 21 and are arranged in groups corresponding to the constraint arms. Some groups of constraint arms are used to constrain the corresponding constraint cavities in the vertical direction, while others are used to constrain the corresponding constraint cavities in the horizontal direction. This ensures the reliability of the constraint between the constraint arms and the constraint cavities. Furthermore, in other embodiments, when the constraint arms are not cylindrical and the corresponding constraint cavities are hole-like structures, only one constraint arm may be provided, as long as the constraint reliability when the constraint arm and the constraint cavity are engaged is ensured.

[0049] In this embodiment, power terminals 101 are arranged in pairs. The constraint arm includes a guide post extending to the front end of the paired power terminals 101. Correspondingly, adapter terminals 201 are arranged in pairs on the adapter socket 2, and a constraint cavity is provided corresponding to the guide post. During the insertion process, the insertion time of the guide post and the constraint cavity is earlier than the insertion time of the power terminals 101 and the adapter terminals 201. Thus, when the device socket 1 and the adapter socket 2 are inserted, the guide post and the corresponding constraint cavity guide and engage first. After this guiding engagement, the power terminals 101 and the adapter terminals 201 will come into contact, ensuring accurate insertion of the power terminals 101 and the adapter terminals 201 and avoiding collisions and deformations of the power terminals 101 and the adapter terminals 201 due to positional deviations. The rear end of the guide post is also provided with a guide ramp 107 to facilitate engagement with the corresponding constraint cavity.

[0050] In this embodiment, the guide post is positioned between two pairs of power terminals 101. Correspondingly, as... Figure 3 As shown, the constraint cavity includes a guide groove located between two adapter terminals 201 on the adapter socket 2. Thus, the guide post can guide the two sockets at a position between the paired power terminals 101. Furthermore, in other embodiments, the guide post may also be located outside the paired power terminals 101, and the guide groove may also be correspondingly located outside the paired adapter terminals 201, provided that reliable guidance is ensured.

[0051] In this embodiment, there are two pairs of power terminals 101, and the length of one pair protruding rearward from the connecting flange 108 is greater than the length of the other pair protruding rearward from the connecting flange 108. Correspondingly, there are two pairs of adapter terminals 201, with the adapter ends 206 of the two pairs of adapter terminals 201 arranged one in front of the other, and the adapter end 206 of the rear adapter terminal 201 being lower than the adapter end 206 of the front adapter terminal 201. Of course, it is easy to imagine that in another embodiment, the lengths of the two pairs of power terminals 101 protruding rearward from the connecting flange can also be equal, in which case the adapter ends 206 of the adapter terminals 201 are flush. In addition, in other embodiments, multiple pairs of power terminals 101 can be provided, or even just one pair, with the number and position of the adapter terminals 201 corresponding to the power terminals 101.

[0052] Meanwhile, there are two pairs of power terminals 101, and the guide post is positioned between the two pairs of power terminals 101, such as... Figure 1 As shown, the guide post includes a first guide post 102 and a second guide post 104. The first guide post is located between a first pair of power terminals 101, and the second guide post is located between a second pair of power terminals 101. Correspondingly, the guide groove includes... Figure 3 The first guide groove 202 and the second guide groove 204 shown are located between the first pair of adapter terminals 201 and the second guide groove is located between the second pair of adapter terminals 201.

[0053] In this embodiment, the adapter terminal 201 is a bent terminal with a 90° bend, and the end used for connecting to the printed circuit board extends upward beyond the adapter housing 21, while the adapter end 206 extends forward, as shown below. Figure 6 As shown, the connecting end 207 of the adapter terminal 201 is a insert structure, and the adapter end 206 is a clip structure. The insert and clip structures are arranged at a 90-degree angle. The lower side of the adapter housing 21 is open, and the open portion corresponds vertically to the mounting cavity for installing the adapter terminal 201. The adapter terminal 201 is inserted into the adapter terminal mounting cavity from the lower open side. The open design of the adapter housing 21 ensures heat dissipation for the adapter terminal 201 and the power terminal 101, preventing overheating of the connector socket on the printed circuit board 3. The adapter terminal 201 is provided with barbs 205, and is press-fitted to the adapter housing 21 through the barbs 205. The guide groove opens downward, which facilitates the arrangement of the adapter housing 21 with the lower open side. In addition, in other embodiments, the adapter housing may also be a circumferentially closed structure, but it must ensure that there is sufficient installation space inside for installing the adapter terminal. In this case, the guide groove may also open upward. In other embodiments, the adapter terminal may also be a straight terminal extending from front to back, with the rear end being the connection end and the front end being the adapter end. The adapter terminal mounting cavity extends from front to back, and the adapter terminal is interference-fitted into the adapter housing from front to back.

[0054] In this embodiment, the protruding section of the longer power terminal 101 at the front of the mating end is wrapped by a wrapping section 105 integral with the socket housing 110. The constraint arm includes an anti-deviation rib 103 on the wrapping section 105 that mates with the anti-deviation groove 203 of the adapter socket 2. The adapter housing 21 has a wrapping section cavity inside the adapter terminal 201 at the rear of the adapter end 206, for the wrapping section 105 of the socket housing 110 to be inserted. The cavity wall of the wrapping section cavity has an anti-deviation groove 203 for mates with the anti-deviation rib 103 on the device end socket 2. The mating time of the anti-deviation rib 103 and the anti-deviation groove 203 is earlier than the mating time of the power terminal 101 and the adapter terminal 201. In this way, the accuracy of the mating of the power terminal 101 and the adapter terminal 201 is further improved, and the collision and deformation of the power terminal 101 or the adapter terminal 201 caused by positional deviation are avoided.

[0055] In this embodiment, two pairs of power terminals 101 are arranged horizontally and vertically. Correspondingly, two pairs of adapter terminals 201 are arranged horizontally and vertically. The anti-deviation rib 103 is located on the left and right sides of the corresponding power terminals 101. In this embodiment, the adapter end 206 of the adapter terminal 201 in the adapter socket 2 is located on the lower side. The length of the upper power terminal 101 protruding backward from the connecting flange is less than the length of the lower power terminal 101 protruding backward from the connecting flange. The anti-deviation rib 103 is located on the outer surface of the wrapping section 105 of the lower pair of power terminals 101. In addition, in other embodiments, the anti-deviation rib can also be located on the inner side of the wrapping section of the corresponding power terminal, as long as its anti-deviation guiding function is guaranteed. Of course, in another embodiment, the two pairs of power terminals can also be arranged vertically and alternately, with the anti-deviation rib located on the left and right sides or the inner side of the wrapping section of the corresponding power terminal.

[0056] In this embodiment, the engagement time of the anti-deviation rib 103 and the anti-deviation groove 203 is earlier than the engagement time of the guide post and the corresponding constraint cavity. Furthermore, in other embodiments, the engagement time of the guide post and the constraint cavity may also be earlier than the engagement time of the anti-deviation rib and the anti-deviation groove.

[0057] In this embodiment, the socket housing 110 further includes a connecting plate 106 integrally connecting the two wrapping sections 105, with guide posts disposed at the end of the connecting plate 106. This further improves the structural strength of the guide posts. In other embodiments, the guide posts may not be disposed on the connecting plate, but rather at other locations between the paired power terminals. In this embodiment, the lower side of the adapter housing 21 is open, allowing the connecting plate 106 to engage with the lower part of the adapter housing 21.

[0058] Another aspect of this utility model provides an adapter socket. Since the adapter socket 2 is the same as the embodiment of the adapter socket 2 described above, it will not be described again here.

[0059] Another aspect of this utility model provides a device end socket. Since the device end socket 1 is the same as the embodiment of the device end socket 1 described above, it will not be described again here.

The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
