Description

Technical Field

[0001] This invention relates to a socket for a signal connector and a signal connector, belonging to the field of connector technology. Background Technology

[0002] Miniaturization and automated production for soldering to PCBs are the development trends for automotive signal connectors. Signal connectors include sockets and plugs that mate with the sockets. For example... Figure 1 As shown, the socket includes a housing 100, bounded by boundary line A of the PCB board 400. The housing 100 includes an overlapping housing section 102 for mounting on the PCB board 400 (i.e., printed circuit board) and an overhanging housing section 101 extending beyond the PCB board 400. The end of the overhanging housing section 101 is provided with a socket 103 for mating with a plug. Conductive terminals 200 are disposed within the housing 100. The conductive terminals 200 can be installed within the housing 100 by assembly or integral molding with the housing 100. The conductive terminals 200 are L-shaped and include a contact section 201 and a plug-in section 202 arranged perpendicularly to each other. The end of the contact section 201 is located within the overhanging housing section 101 and is used to contact the conductive terminals in the plug. The plug-in section 202 is located within the overlapping housing section 102, and the lower end of the plug-in section 202 forms a pin for insertion and soldering to the PCB board 400. To ensure the positional accuracy of the pins, the socket may also include a rear pressure plate 300 that is snapped onto the housing 100, and the rear pressure plate 300 is provided with positioning holes 301 for the pins to pass through.

[0003] like Figure 1 As shown, in the prior art, the center of gravity B of the socket is located outside the PCB board 400 and does not correspond to the PCB board 400. Therefore, for sockets that overlap the PCB board 400 and whose pins are not soldered to the PCB board 400, it is easy for them to "droop". Specifically, this manifests as the downward tilt of the overhanging shell section and the upward tilt of the overlapping shell section. The upward tilt of the overlapping shell section will affect the soldering of the pins and the PCB board, and thus affect the automated production of socket and PCB board soldering.

[0004] In existing technologies, to address the "tilting" phenomenon of sockets, two spring arms are positioned on either side of the pin arrangement direction on the overlapping housing section. A locking groove is provided on the PCB board to engage with these spring arms, thus limiting the upward tilt of the overlapping housing section and resolving the "tilting" issue. However, a problem exists: if the spring arms are engaged too tightly, they are prone to breakage and may sometimes fail to engage properly. Conversely, if the engagement is too loose, the "tilting" problem remains unresolved. Therefore, this assembly method places high demands on both manufacturing precision and product consistency. Improving manufacturing precision and product consistency helps control the tightness of the engagement between the spring arms and the locking groove within a certain range, but this increased precision and consistency also complicates manufacturing. Summary of the Invention

[0005] The purpose of this invention is to provide a socket for a signal connector to solve the problem of increased manufacturing difficulty caused by the use of spring arms and slots to solve the "head-down" phenomenon in the prior art; the purpose of this invention is also to provide a signal connector to solve the above problems.

[0006] To achieve the above objectives, the signal connector socket of the present invention adopts the following technical solution:

[0007] A socket for a signal connector includes a housing, which includes a lap-on housing section for lapping onto a printed circuit board and a cantilever housing section extending out of the printed circuit board. The housing contains conductive terminals with pins for fixed connection with the printed circuit board. The lap-on housing section is provided with a counterweight structure to adjust the center of gravity of the socket to a position corresponding to the printed circuit board.

[0008] The beneficial effects of the above technical solution are as follows: In the signal connector socket of the present invention, since a counterweight structure is provided on the overlapping shell section, the center of gravity of the socket can be adjusted to the position corresponding to the printed circuit board by the gravity of the counterweight structure. In this way, the gravity of the counterweight structure restricts the upward tilt of the overlapping shell section and the downward tilt of the cantilever shell section, that is, it can restrict the "head-down" phenomenon of the socket, ensure effective contact between the pins and the printed circuit board and the soldering effect between the pins and the printed circuit board, and facilitate the realization of automated soldering production. Compared with the prior art, the present invention solves the "head-down" phenomenon of the socket by setting a counterweight structure on the overlapping shell section. Not only are there no high requirements for the size and processing accuracy of the product, but also, since it is only necessary to adjust the center of gravity of the socket to the position corresponding to the printed circuit board by using the counterweight structure, there are no high requirements for product consistency. Therefore, by setting a counterweight structure, the processing difficulty can be reduced, which is conducive to the processing and manufacturing of the product.

[0009] Furthermore, a rear pressure plate is connected to the overlapping housing section, and the rear pressure plate is provided with positioning holes for the pins to pass through and position the pins. The counterweight structure is provided on the rear pressure plate.

[0010] The advantages of the above technical solution are as follows: It allows for pin positioning via the positioning holes on the rear pressure plate, ensuring pin dimensional accuracy. Furthermore, since the rear pressure plate is connected to the overlapping housing section, the counterweight structure can be indirectly mounted on the overlapping housing section by placing it on the rear pressure plate. Additionally, mounting the counterweight structure on the rear pressure plate also facilitates the processing and manufacturing of the housing.

[0011] Furthermore, the counterweight structure is a counterweight block, and the rear pressure plate is provided with a mounting groove for installing the counterweight block.

[0012] The beneficial effects of the above technical solution are as follows: setting the counterweight structure as a counterweight block simplifies the specific structure of the counterweight structure and facilitates the processing and manufacturing of the counterweight structure; installing the counterweight block through the mounting groove facilitates the installation of the counterweight block on the rear pressure plate, and thus also facilitates the setting of the counterweight structure on the rear pressure plate.

[0013] Furthermore, the pins extend downwards, the slot of the mounting groove faces upwards, and the overlapping housing section includes a left side wall and a right side wall for connecting the rear pressure plate, and a top wall connected between the left and right side walls for sealing the slot.

[0014] The beneficial effects of the above technical solution are as follows: by sealing the opening of the mounting groove with the top wall, the top wall can prevent the counterweight from falling out of the mounting groove, thus ensuring the effective installation of the counterweight within the mounting groove. Furthermore, the left side wall, right side wall, top wall, and rear pressure plate can also reduce the impact of external factors on the interior of the housing to a certain extent.

[0015] Furthermore, the counterweight is interference-fitted into the mounting slot.

[0016] The beneficial effect of the above technical solution is that it further ensures the fixed installation effect of the counterweight in the installation groove, and makes the counterweight installed more stably in the installation groove.

[0017] Furthermore, the counterweight structure is a counterweight block, which is fixed to the rear pressure plate by injection molding, or the counterweight block and the rear pressure plate are assembled by spring arm and slot.

[0018] The advantages of the above technical solution are as follows: Injecting the counterweight onto the rear pressure plate not only ensures the counterweight's fixation on the plate but also eliminates the need for other fixing structures to achieve a secure connection between the counterweight and the rear pressure plate, thus simplifying the manufacturing of the rear pressure plate. Alternatively, by using the snap-fit ​​assembly of the spring arm and slot, both the fixed installation of the rear pressure plate and the counterweight can be guaranteed, while also facilitating their assembly and disassembly.

[0019] Furthermore, the counterweight structure is a counterweight block, which is fixed to the overlapping shell section by injection molding, or the counterweight block and the overlapping shell section are assembled by spring arms and slots.

[0020] The advantages of the above technical solution are as follows: Injecting the counterweight onto the overlapping shell section not only ensures the counterweight's fixation on the overlapping shell section, but also eliminates the need for other fixing structures to achieve a secure connection between the counterweight and the overlapping shell section, thus facilitating the manufacturing of the overlapping shell section. Alternatively, by using the snap-fit ​​assembly of the spring arm and the slot, both the fixed installation effect between the rear pressure plate and the overlapping shell section can be ensured, while also facilitating the assembly and disassembly of the counterweight and the overlapping shell section.

[0021] Furthermore, the counterweight includes a horizontally connected portion and a vertically connected portion, with the vertical portion forming the rear sidewall of the overlapping shell section and the horizontal portion forming the top wall of the overlapping shell section.

[0022] The beneficial effects of the above technical solution are that the horizontal and vertical parts of the counterweight can ensure the isolation effect between the inside and outside of the shell to a certain extent, thereby reducing the influence of external factors on the inside of the shell.

[0023] Furthermore, the overlapping housing section is provided with positioning posts for positioning and engaging with the printed circuit board.

[0024] The beneficial effects of the above technical solution are as follows: by cooperating with the positioning post and the printed circuit board, the accuracy of the socket's installation position on the printed circuit board can be guaranteed, which in turn helps to ensure the soldering and fixing effect of the pins and the printed circuit board.

[0025] To achieve the above objectives, the signal connector in this invention adopts the following technical solution:

[0026] A signal connector includes a socket and a plug that mates with the socket. The socket includes a housing, which includes a lap-on housing section for mounting on a printed circuit board and a cantilever housing section extending out of the printed circuit board.

[0055] The present invention will be further described in detail below with reference to the embodiments.

[0056] Example 1 of the signal connector socket in this invention:

[0057] like Figure 2 and Figure 3 As shown, the socket for the signal connector (hereinafter referred to as the "socket") includes a housing 10. Since the socket is attached to a printed circuit board (hereinafter referred to as the "PCB board"), with the boundary A of the PCB board 80 as the boundary, the housing 10 includes an overlapping housing section 12 for attaching to the PCB board 80 and an overhanging housing section 11 that extends out of the PCB board 80. The overhanging housing section 11 is located in front of the overlapping housing section 12, and the front end of the overhanging housing section 11 is provided with a socket 13 for mating with the plug in the signal connector.

[0058] like Figure 2 and Figure 3 As shown, a conductive terminal 20 is provided inside the housing 10. The conductive terminal 20 is assembled and fitted inside the housing 10. In other embodiments, the conductive terminal 20 can also be integrally formed with the housing 10 and installed inside the housing 10. Figure 3 As shown, the conductive terminal 20 is L-shaped and includes a contact section 21 and a plug section 22 arranged perpendicularly to each other. The contact section 21 extends horizontally, with its end located within the cantilever housing section 11, for contacting the conductive terminal in the plug. The plug section 22 is located within the overlapping housing section 12 and extends downwards; its lower end forms a pin for insertion into a solder hole on the PCB board 80 and for soldering and fixing it to the PCB board 80.

[0059] like Figure 2 and Figure 3 As shown, a rear pressure plate 30 is connected to the overlapping shell section 12. Specifically, the overlapping shell section 12 includes a left side wall 15, a right side wall 16, and a top wall 14 connecting the left and right side walls. The rear pressure plate 30 has vertically extending spring arms 33 on its left and right sides. The spring arms 33 are connected to the overlapping shell section 12 by engaging with the left and right side walls. Figure 2 As shown, the rear pressure plate 30 is provided with positioning holes 34 for pins to pass through and for positioning the pins. The positioning holes 34 are used to position the pins, which can correct the position of the pins and ensure the positional accuracy of the pins, making it convenient for the pins to be inserted into the soldering holes on the PCB board 80.

[0060] A mounting block 31 is provided on the rear pressure plate 30, arranged perpendicularly to the rear pressure plate 30. The mounting block 31 forms the rear sidewall of the housing 10. The mounting block 31 is provided with a mounting groove 32, with the groove opening facing upwards. The socket also includes a separate rectangular counterweight 40. The rectangular counterweight 40 is a metal block, which is installed in the mounting groove 32 and has an interference fit with the mounting groove 32. Figure 3 As shown, the center of gravity C of the socket can be adjusted to a position corresponding to the PCB board 80 by the gravity of the rectangular counterweight 40. Figure 3 As shown, the top wall 14 of the overlapping shell section 12 can cover the opening of the mounting groove 32. By covering the opening of the mounting groove 32 with the top wall 14, the rectangular counterweight 40 can be prevented from falling out of the mounting groove 32, thus ensuring the installation effect of the rectangular counterweight 40 in the mounting groove 32. In addition, since the rectangular counterweight 40 is set on the rear pressure plate 30, and the rear pressure plate 30 is connected to the overlapping shell section 12, the rectangular counterweight 40 constitutes a counterweight structure set on the overlapping shell section 12.

[0061] like Figure 2 and Figure 3As shown, in order to facilitate the insertion of pins into the soldering holes on the PCB board 80, the overlapping housing section 12 is also provided with positioning posts 50 extending in the same direction as the insertion section 22 and used for positioning and cooperating with the printed circuit board. There are two positioning posts 50, which are respectively placed on both sides of the arrangement direction of the insertion section 22. The PCB board 80 is provided with positioning holes 34 for each positioning post 50 to be inserted, and the length of the positioning post 50 is greater than the length of the insertion section 22. In this way, before the pin is inserted into the soldering hole, the positioning post 50 can be inserted into the positioning hole 34 to position the insertion between the pin and the soldering hole.

[0062] In the signal connector socket of the present invention, a counterweight structure is provided on the overlapping shell section. The gravity of the counterweight structure adjusts the center of gravity of the socket to a position corresponding to the printed circuit board. This counterweight structure restricts both the upward tilting of the overlapping shell section and the downward tilting of the cantilever shell section, thus preventing the socket from "tilting down." This ensures effective contact between the pins and the printed circuit board, as well as the soldering effect, facilitating automated soldering production. Compared with existing technologies, the present invention solves the "tilting down" problem by providing a counterweight structure on the overlapping shell section. This not only reduces the requirements for product size and processing precision, but also, since only the center of gravity of the socket needs to be adjusted to the position corresponding to the printed circuit board, there are no high requirements for product consistency. Therefore, the counterweight structure reduces processing difficulty and facilitates product manufacturing.

[0063] Embodiment 2 of the signal connector socket in this invention:

[0064] The difference between this embodiment and Embodiment 1 is that, in this embodiment, as... Figure 4 As shown, the counterweight structure is an L-shaped counterweight block 70, which is separately arranged from the rear pressure plate 60 and the housing 10. The overlapping housing section 90 is provided with an open structure adapted to the L-shaped counterweight block 70. The L-shaped counterweight block 70 is a metal block, which includes a horizontal part 71 and a vertical part 72 connected vertically. The vertical part 72 forms the rear side wall of the overlapping housing section 90, and the horizontal part 71 forms the top wall of the overlapping housing section 90. The lower part of the vertical part 72 is provided with a slot 73, and the rear pressure plate 60 is provided with a locking arm 61 for engaging with the slot 73. The L-shaped counterweight block 70 can be fixedly installed on the overlapping housing section 90 by engaging with the slot 73.

[0065] In other embodiments of the signal connector socket, unlike embodiment 2, the slot may not be provided on the vertical part of the L-shaped counterweight, and the spring arm may not be provided on the rear pressure plate. Instead, the slot is provided on the rear pressure plate, and the spring arm is provided on the vertical part of the L-shaped counterweight.

[0066] In other embodiments of the signal connector socket, unlike embodiment 2, the left and right sides of the horizontal portion of the L-shaped counterweight can be provided with corresponding left and right side walls, and the left and right side walls constitute the left and right side walls of the overlapping housing section.

[0067] In other embodiments of the signal connector socket, unlike embodiment 1, the counterweight may not be rectangular, but rather trapezoidal or triangular, etc.

[0068] In other embodiments of the socket for the signal connector, the counterweight and the overlapping housing segment are assembled by a spring arm and a slot. Specifically, the spring arm is disposed on the counterweight and the slot is disposed on the overlapping housing segment. In other embodiments, the spring arm may be disposed on the overlapping housing segment and the slot may be disposed on the counterweight.

[0069] In other embodiments of the socket for the signal connector, the counterweight may not be separate from the overlapping housing segment, but may be fixed to the overlapping housing segment by injection molding. In this case, the counterweight may be a metal block or a counterweight made of the same material as the overlapping housing segment.

[0070] In other embodiments of the socket for the signal connector, the counterweight may not be separate from the rear pressure plate, but may be fixed to the rear pressure plate by injection molding. In this case, the counterweight may be a metal block or a counterweight made of the same material as the rear pressure plate.

[0071] In other embodiments of the signal connector socket, the counterweight does not have an interference fit with the mounting slot. In this case, the counterweight can only be prevented from falling out of the mounting slot by the top wall of the overlapping housing section sealing the opening of the mounting slot.

[0072] In other embodiments of the socket for the signal connector, the top wall of the overlapping housing section does not cover the opening of the mounting groove, and the counterweight is installed in the mounting groove by interference fit with the mounting groove.

[0073] In other embodiments of the signal connector socket, a rear pressure plate is not provided. In this case, the counterweight structure can only be provided on the overlapping housing section, and the pins are not positioned.

[0074] In other embodiments of the signal connector socket, no positioning post is provided. In this case, the pins can only be connected and mated with the solder holes on the PCB board by themselves.

[0075] In other embodiments of the signal connector socket, the counterweight structure is not set independently, but is integrally formed with the rear pressure plate. The counterweight structure is composed of a part of the structure of the rear pressure plate, such as a mounting block set on the rear pressure plate. Alternatively, the counterweight structure is integrally formed with the overlapping housing section. The counterweight structure is composed of a part of the structure of the overlapping housing section, such as the left and right side walls or the top wall of the overlapping housing section.

[0076] An embodiment of the signal connector in this invention: The signal connector includes a socket and a plug that mates with the socket. The specific structure of the socket is the same as that of the socket in the above embodiment of the signal connector socket, and will not be repeated here.

[0077] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
