Description

Technical Field

[0001] This utility model belongs to the field of connection devices, and in particular relates to a connector protective shell assembly and a connector. Background Technology

[0002] A bent backplane connector typically includes an insulating shell and multiple terminal modules that are assembled and connected to the insulating shell. The front end of the terminal module is a mating part for mating with the adapter connector, and the bottom end of the terminal module is provided with a fisheye. During assembly, the mating part is assembled inside the insulating shell.

[0003] Chinese invention patent application CN112636101A discloses a connector comprising a housing, a fixing plate, and multiple transversely arranged chips (i.e., terminal modules). The mating portions of the chips are inserted into the housing (i.e., the insulating shell), while the remaining portions are exposed. The fixing plate has a comb-like structure, and the rear ends of the chips have insertion structures for engaging with the comb-like structure. The fixing plate connects the rear ends of the chips together. In use, the connector needs to be press-fitted onto a printed circuit board. This operation utilizes a pressing fixture to apply pressure from the ends of the connector furthest from the "fisheye" (the hole in the connector's surface), then presses the "fisheye" into the corresponding holes on the printed circuit board. However, the portions of the chips outside the housing are difficult to protect effectively, and even after being pressed into place, the chips are still subjected to significant pressure from the pressing fixture, potentially leading to breakage or damage.

[0004] Furthermore, to facilitate the assembly of various terminal modules and prevent short circuits of differential pairs within the terminal modules, the connector housing is typically made of insulating plastic, which has poor resistance to deformation. In the aforementioned connector, the housing has mounting holes for securing the connector to the printed circuit board with bolts. During mating with the adapter connector, the connector is subjected to upward pressure in the front-to-back direction. Because the insulating housing is prone to deformation, this force is transmitted to the fisheye, potentially causing deformation and affecting normal signal transmission. Utility Model Content

[0005] One of the objectives of this utility model is to provide a connector protective shell assembly to solve the technical problem in the prior art that after the various terminal modules of the connector are pressed into place, they are still subjected to a large pressure applied by the pressing tool, which makes the terminal modules easy to be damaged.

[0006] One of the objectives of this invention is to provide a connector to solve the aforementioned technical problems.

[0007] To achieve the above objectives, the technical solution for the connector protective shell assembly provided by this utility model is as follows:

[0008] A connector protective shell assembly includes a fixing plate, with two pressure-bearing limiting members fixed at its two transverse ends. The two pressure-bearing limiting members are arranged laterally at a distance from each other. The fixing plate and the two pressure-bearing limiting members form a cavity for accommodating a terminal module. The two longitudinal ends of the pressure-bearing limiting members are respectively used for supporting and engaging with the surface of a printed circuit board and the inner side of the fixing plate. The pressure-bearing limiting members meet the requirement that their longitudinal pressure-bearing capacity is not less than the working pressure of the press-fitting fixture, so that when the terminal module is assembled in place, the pressure-bearing limiting members can bear the pressure of the press-fitting fixture and limit the press-fitting distance of the press-fitting fixture.

[0017] As a further improvement, the connector's protective housing assembly also includes an insulating housing. The rear longitudinal sides of the insulating housing are provided with rearwardly extending assembly connecting plates, which are provided with locking holes. The longitudinal ends of the pressure-bearing limiting member are provided with housing buckle protrusions. The pressure-bearing limiting member can be inserted from back to front between the two assembly connecting plates of the insulating housing, and the housing buckle protrusions are embedded in the locking holes.

[0018] The beneficial effects are: this connector protective housing assembly is an improvement on existing technology. By providing pressure-bearing limiting members on both sides of the fixing plate, this assembly allows the pressure-bearing limiting members to bear pressure and restrict movement of the pressing fixture after the terminal module is pressed into place during the connector installation onto the printed circuit board, thereby preventing the terminal module from being damaged by excessive pressure.

[0019] To achieve the above objectives, the technical solution for the connector provided by this utility model is as follows:

[0020] A connector includes a plurality of transversely arranged terminal modules and a connector protective shell assembly mounted on the outside of the terminal modules for providing support and limiting during the press-fitting process. The connector protective shell assembly includes a fixing plate, and two pressure-bearing limiting members are fixed at both transverse ends of the fixing plate. The two pressure-bearing limiting members are arranged transversely at intervals. The fixing plate and the two pressure-bearing limiting members form a cavity for accommodating the terminal modules. The longitudinal ends of the pressure-bearing limiting members are respectively used for supporting and engaging with the surface of a printed circuit board and supporting and engaging with the inner side of the fixing plate. The pressure-bearing limiting members meet the requirement that their longitudinal pressure-bearing capacity is not less than the working pressure of the press-fitting fixture, so that when the terminal modules are assembled in place, the pressure-bearing limiting members can bear the pressure of the press-fitting fixture and limit the press-fitting distance of the press-fitting fixture.

[0021] As a further improvement, the pressure-bearing limiting component is provided with a support structure to enhance its longitudinal pressure-bearing capacity.

[0022] As a further improvement, the support structure includes support beams and support columns. The support beams extend in the front-to-back direction and are disposed at both ends of the longitudinal direction of the pressure-bearing limiting member.

[0023] As a further improvement, the pressure-bearing limiting component is a support side plate, the support side plate is thickened around its perimeter, the thickened portions at both ends of the longitudinal direction of the support side plate form a support beam, and the thickened portions at the front and rear ends of the support side plate form a support column that connects and supports the two support beams.

[0024] As a further improvement, the fixing plate is provided with a comb structure that can be inserted and fixed with the module insertion structure on the terminal module, and the pressure-bearing limiting member is provided with a housing insertion structure for insertion and engagement with the comb structure, with the housing insertion structure located at one end in its longitudinal direction.

[0025] As a further improvement, the fixing plate includes a top plate and a rear plate that are perpendicular to each other. The top plate is located at one longitudinal end of the two pressure-bearing limiting members, and the inner side of the top plate is supported and engaged with the corresponding end face of the pressure-bearing limiting members. The rear plate is located at the rear end of the two supporting side plates, and the comb structure is set at the end of the top plate away from the rear plate.

[0026] As a further improvement, a mating hole is provided on the rear plate, and a housing mounting protrusion is provided on the pressure-bearing limiting component to be embedded and connected with the mating hole.

[0049] The present invention will be further described in detail below with reference to the embodiments.

[0050] To address the problems in the prior art, the basic concept of this utility model is to provide pressure-bearing limiting members on both sides of each terminal module for support and protection, thereby preventing the terminal module from being subjected to excessive pressure after being pressed into place.

[0051] Specific embodiment 1 of the connector provided by this utility model:

[0052] This connector is a right-angle connector; see attached... Figure 1 and attached Figure 2 The connector includes a connector housing assembly and terminal modules 1. Terminal modules 1 are assembled inside the connector housing assembly and are protected by the connector housing assembly. The connector and the adapter connector are mated in a front-to-back direction. The end used to mate with the adapter connector is its front end. The terminal modules 1 in the connector are arranged in a transverse direction. The direction perpendicular to both the front-to-back direction and the transverse direction is the longitudinal direction. One end of the connector in the longitudinal direction is used to connect to the printed circuit board 6 and this end is its bottom end. The other end of the connector in the longitudinal direction is its top end.

[0053] Terminal module 1 includes an insulator, signal terminals integrally injection molded in the insulator, and shielding sheets fixed to the transverse sides of the insulator by secondary heat riveting. The signal terminals are arranged in differential pairs. One end of the signal terminal extends from the front end of the insulator and forms a plug-in mating end, while the other end of the signal terminal extends from the bottom end of the insulator and forms a fisheye.

[0054] The connector protective housing assembly includes an insulating shell 2, a pressure-bearing limiting member, and a fixing plate 4. The insulating shell 2 is made of plastic, the fixing plate 4 is made of metal sheet by stamping and bending, and the pressure-bearing limiting member is a support side plate 3 made of metal material by machining. The support side plate 3 can also be formed by powder metallurgy, or the support side plate 3 can also be made of rigid plastic with high rigidity.

[0055] See appendix Figure 9 and in conjunction with the appendix Figure 10 Appendix Figure 11 Appendix Figure 12 The rear end of the insulating shell 2 is provided with an installation port for inserting each terminal module 1. The rear ends of the two longitudinal side walls of the installation port extend rearward to form an assembly connecting plate 21, which is provided with a locking hole 22. The top and bottom of the insulator of the terminal module 1 are provided with module locking protrusions 11. The module locking protrusions 11 have a barbed structure. During the process of assembling the front end of each terminal module 1 into the installation port of the insulating shell 2, the module locking protrusions 11 are embedded into the corresponding locking holes 22 to prevent the terminal module 1 from falling out rearward.

[0056] Combined with appendix Figure 3 The fixing plate 4 includes a top plate 41 and a rear plate 42 that are perpendicular to each other. The top plate 41 is perpendicular to the longitudinal direction, and the rear plate 42 is perpendicular to the front-rear direction. The top plate 41 is located on one side of the top of each terminal module 1, and the rear plate 42 is located on the rear side of each terminal module 1. The front end of the top plate 41 is provided with a comb tooth structure 43, and the top end of the terminal module 1 is provided with a module insertion structure 12 that is inserted and fitted with the comb tooth structure 43. The rear plate 42 is provided with a mating hole 44, and the rear end of the insulator of the terminal module 1 is provided with a module embedding protrusion 13 that can be inserted into the mating hole 44. Each terminal module 1 can be connected together by the fixing plate 4, which improves the overall integrity of each terminal module 1.

[0057] See appendix Figure 4 and in conjunction with the appendix Figure 5 Appendix Figure 6 and attached Figure 7 Two support side plates 3 are provided, which are parallel to each other and arranged laterally. Each terminal module 1 is clamped between the two support side plates 3. The top of the support side plate 3 is provided with a housing insertion structure 31 for inserting and engaging with the comb tooth 43 structure on the fixing plate 4. The rear end of the support side plate 3 is provided with a housing insert protrusion 32 for inserting and connecting with the mating hole 44 on the fixing plate 4. The top plate 41 of the fixing plate 4 is connected between the top ends of the two support side plates 3, and the rear plate 42 of the fixing plate 4 is connected between the rear ends of the two support side plates 3. The fixing plate 4 and the two support side plates 3 form a cavity for accommodating each terminal module 1.

[0058] The module insertion structure 12 and the housing insertion structure 31 have the same shape and size. Taking the housing insertion structure 31 as an example, the housing insertion structure 31 includes an insertion part for inserting into the comb tooth 43 structure between two comb teeth 43. The lateral sides of the insertion part are tightly fitted with the corresponding comb teeth 43. The rear end of the insertion part is provided with a beveled guide structure for guiding the comb teeth 43. The insertion part 311 is integrally connected to the top of the main body part 35 of the support side plate 3. The lateral dimension of the insertion part 311 is smaller than the lateral dimension of the top of the main body part 35 of the support side plate 3. The housing insertion structure 31 also includes a limiting part 312 integrally connected to the top of the insertion part 311. The lateral dimension of the limiting part 312 is larger than the lateral dimension of the insertion part 311. The limiting part 312 and the top of the main body part 35 respectively limit the comb teeth 43 of the comb tooth 43 structure on both sides in the longitudinal direction to prevent the comb tooth 43 structure from moving in the longitudinal direction.

[0059] See appendix Figure 3The comb teeth 43 of the comb tooth structure are arranged laterally, with the comb teeth 43 located at the two lateral edges being shorter than the other comb teeth 43. The comb teeth 43 and the insert structure (module insert structure 12 or housing insert structure 31) they contact exert a clamping force laterally. The comb teeth 43 in the middle are clamped by the insert structure on both sides laterally, but the comb teeth 43 located at the two lateral edges are clamped by the insert structure on only one side. Therefore, these comb teeth 43 are prone to outward bending and deformation. If the length of the comb teeth 43 is long, its resistance to deformation will decrease, making it easier to bend and deform outward, causing the ends of the comb teeth 43 to protrude beyond the outer surface of the supporting side plate 3. Moreover, the longer the comb teeth 43 are, the longer the protrusion. Shortening the comb teeth 43 located at the two lateral edges can improve their resistance to deformation and reduce the protrusion length.

[0060] The module mounting protrusion 13 and the housing mounting protrusion 32 have the same shape, but the housing mounting protrusion 32 is slightly smaller than the module mounting protrusion 13, so that the housing mounting protrusion 32 has a clearance fit with the corresponding mating hole 44. Since the support side plate 3 is a metal part, it is less prone to elastic deformation than a plastic part. Therefore, the clearance fit between the housing mounting protrusion 32 and the mating hole 44 facilitates the assembly of the fixing piece 4 and the support side plate 3. The module mounting protrusion 13 can have a clearance fit with the mating hole 44 or an interference fit. In this embodiment, there are two housing mounting protrusions 32 on the support side plate 3, located in the middle and upper parts of the rear end of the support side plate 3, respectively.

[0061] The supporting side plate 3 and the fixing piece 4 are located behind the insulating shell 2, and the front end of the supporting side plate 3 is inserted and fixed to the insulating shell 2. Specifically, the front end of the main body 35 of the supporting side plate 3 is integrally provided with three forward-protruding insertion protrusions 33, see attached figure. Figure 9 The rear end faces of the transverse side walls of the mounting port of the insulating shell 2 are provided with slots 23 for insertion of the protrusions 33. There are three slots 23 arranged longitudinally. See Appendix. Figure 13 and in conjunction with the appendix Figure 14 and attached Figure 15 The three slots 23 and the three protrusions 33 are inserted into each other in a corresponding manner. The front end of the protrusion 33 is chamfered to guide the insertion process.

[0062] The supporting side plate 3 is connected to the insulating shell 2 by three plug-in protrusions. On the one hand, it is not necessary to set continuous slots 23 on the insulating shell 2, which can improve the overall strength of the insulating shell 2. On the other hand, it can also reduce the contact area between the supporting side plate 3 and the insulating shell 2, thereby reducing the plug-in resistance between the supporting side plate 3 and the insulating shell 2.

[0063] The assembly connecting plate 21 of the insulating shell 2 is also provided with a locking hole 22 at the position corresponding to the support side plate 3. The top and bottom ends of the support side plate 3 are provided with shell buckle protrusions 34 that are embedded and connected to the corresponding locking holes 22. The shell buckle protrusions 34 have a barbed structure. The cooperation between the shell buckle protrusions 34 and the corresponding locking holes 22 can prevent the support side plate 3 from coming off backward.

[0064] The assembly connecting plate 21 of the insulating shell 2 is provided with a notch 24. The notch 24 is located between the part of the assembly connecting plate 21 corresponding to the support side plate 3 and the part corresponding to the terminal module 1. This makes it easier for the part of the assembly connecting plate 21 corresponding to the support side plate 3 to deform during the assembly of the support side plate 3, which facilitates the assembly of the support side plate 3.

[0065] The outer side of the bottom end of the support side plate 3 is provided with mounting holes 37 for bolts 7, thereby facilitating the fixed connection between the support side plate 3 and the printed circuit board 6 using bolts 7. For details, see Appendix. Figure 4 and in conjunction with the appendix Figure 8 A connecting lug 36 is integrally connected to the outer side of the main body 35 of the supporting side plate 3, and a mounting hole 37 extends longitudinally through the connecting lug 36. In this embodiment, the mounting hole 37 is a threaded hole, and the bolt 7 passes through the corresponding connecting hole on the printed circuit board 6 and is threadedly connected to the mounting hole 37. A clearance groove for avoiding the bolt 7 is provided above the connecting lug 36 on the outer side of the main body 35 of the supporting side plate 3.

[0066] The support side plate 3 is provided with a support structure to enhance its longitudinal pressure-bearing capacity. After the support structure is installed, the longitudinal pressure-bearing capacity of the pressure-bearing limiting member is not less than the working pressure of the press-fitting tool. The support structure includes a support beam 310 and a support column 311. The support beam 310 extends in the front-rear direction and is provided at both ends of the longitudinal direction of the pressure-bearing limiting member. The support column 311 connects to and supports the support beam 310 at both ends of the longitudinal direction of the pressure-bearing limiting member.

[0067] In this embodiment, the support side plate 3 is thickened around its perimeter, and the thickened portions at both ends of the longitudinal direction of the support side plate 3 form support beams 310. The thickened portions at the front and rear ends of the support side plate 3 form support columns 311 that connect and support the two support beams 310. The support structure formed by thickening the support side plate 3 around its perimeter can effectively improve its longitudinal load-bearing capacity, and can also make its end faces at both ends of the longitudinal direction wider, improving load-bearing stability, while keeping its middle part relatively thin to avoid excessive weight.

[0068] In other embodiments, a longitudinally extending reinforcing rib may be provided at the middle position of the support side plate 3. This reinforcing rib serves to connect and support the crossbeams at both ends of the longitudinal direction, and has the same function as the support column 311.

[0069] In other embodiments, the support structure may also be a rectangular support frame that is fixed to one side of the support side plate 3 by welding, wherein two side frames of the support frame are support beams 310 and the other two side frames are support columns 311.

[0070] During the press-fitting of the connector onto the printed circuit board 6, a pressing force needs to be applied to the top of the terminal module 1, especially at the position directly opposite the fisheye. This pressing force is transmitted to the fisheye through the insulator of the terminal module 1, thus pressing the fisheye into the corresponding hole on the printed circuit board 6. The position on the top of the terminal module 1 that bears the pressing force is the module bearing portion. The position on the top of the supporting side plate 3 corresponding to the module bearing portion is the side plate bearing portion 38. The side plate bearing portion 38 is also the top surface of the support beam 310 at the top of the supporting side plate 3, and its surface is flush with the surface of the module bearing portion. During the press-fitting process, the side plate bearing portion 38 is also subjected to pressing force. After the terminal module 1 is pressed into place, the bottom end of the supporting side plate 3 contacts the surface of the printed circuit board 6. At this point, the supporting side plate 3 provides support, preventing the terminal module 1 from being damaged by excessive pressure.

[0071] In this embodiment, the top plate 41 of the fixing plate 4 covers the outside of the module bearing part and the side plate bearing part 38. The pressing force first acts on the top plate 41 of the fixing plate 4, and after being uniformly transmitted by the fixing plate 4, it is transmitted to the terminal module 1 and the supporting side plate 3. The fixing plate 4 can transmit the force through direct contact between the top plate 41 and the module bearing part and the side plate bearing part 38, and can also transmit the force to the module mounting protrusion 13 and the housing mounting protrusion 32 through the rear plate 42, further uniformizing the force.

[0072] The support side plate 3 is directly and fixedly connected to the printed circuit board 6, and the support side plate 3 is also connected to each terminal module 1 through fixing pieces 4 to form an integral structure. Therefore, during the mating process of the connector and the adapter connector, the mating force can be transferred from the terminal module 1 to the support side plate 3. Since the support side plate 3 is a metal part, its deformation resistance is better than that of plastic parts, so it can provide good support for the terminal module 1, thereby avoiding the fisheye deformation on the terminal module 1 from affecting the normal transmission of signals.

[0073] During assembly, each terminal module 1 is first assembled and connected to the insulating shell 2 one by one. During this process, the support side plate 3 is also assembled with the insulating shell 2. Then, the fixing plate 4 is installed, and the support side plate 3 and the terminal module 1 are connected into a whole using the fixing plate 4. Finally, after the connector is pressed onto the printed circuit board 6, the support side plate 3 is fixedly connected to the printed circuit board 6 using bolts 7.

[0074] Specific embodiment 2 of the connector provided by this utility model:

[0075] This embodiment is based on Embodiment 1, and the difference from Embodiment 1 is as follows (see Appendix). Figure 16 In this embodiment, the mounting hole 37 is a countersunk hole machined on the connecting lug 36. A threaded sleeve 5 is countersunk in the countersunk hole. The inner side of the threaded sleeve 5 is machined with threads for threaded connection with the bolt 7. An anti-rotation protrusion is provided on the outer side of the threaded sleeve 5. An anti-rotation groove is provided on the inner side of the countersunk hole to fit into the anti-rotation protrusion. The threaded sleeve 5 is inserted into the countersunk hole from the top of the countersunk hole.

[0076] During installation, the bolt 7 first passes through the corresponding connecting hole on the printed circuit board 6 and then connects with the threaded sleeve 5. After tightening the bolt 7, the bolt 7 generates a tension force on the threaded sleeve 5, which in turn causes the threaded sleeve 5 to press the connecting lug 36 onto the printed circuit board 6.

[0077] In this embodiment, the threaded sleeve 5 and the mounting hole 37 are prevented from rotating by the cooperation of the anti-rotation protrusion and the anti-rotation groove. The threaded sleeve 5 and the mounting hole 37 are stopped by setting the mounting hole 37 as a countersunk hole.

[0078] In other embodiments of this example, the threaded sleeve 5 and the mounting hole 37 can be directly welded together to achieve anti-rotation and anti-movement.

[0079] Because the threaded sleeve 5 is small in size and has a relatively simple structure, it is easier to machine the threads on the threaded sleeve 5 than to machine the threads directly on the support side plate 3, thus achieving higher processing efficiency and lower processing costs.

[0080] Specific embodiment 3 of the connector provided by this utility model:

[0081] This embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that the buckle protrusion is an assembly buckle protrusion provided on the assembly connecting plate. The top and bottom ends of the support side plate are provided with buckle holes that fit into the assembly buckle protrusion. Furthermore, the buckle holes on the support side plate are blind holes.

[0082] Specific embodiment 4 of the connector provided by this utility model:

[0094] In this embodiment, the back plate only serves a protective function. In order to ensure better support and protection for each terminal module, the bottom end of the back plate is flush with the bottom end of the support side plate. This way, after the fisheye press-fit of the terminal module is in place, the back plate can support it on the printed circuit board in time, avoiding damage to the terminal module due to excessive pressure.

[0095] Specific embodiment 9 of the connector provided by this utility model:

[0096] This embodiment is based on embodiment 1. The difference between this embodiment and embodiment 1 is that the fixing plate in this embodiment only includes the top plate. The comb structure is set on the top plate. Since the top plate is connected to the supporting side plate, the pressing pressure can be transmitted to the supporting side plate. When the fisheye of the terminal module is pressed into place, the supporting side plate can support it on the printed circuit board in time, so as to avoid the terminal module being damaged by excessive pressure.

[0097] Specific embodiment 10 of the connector provided by this utility model:

[0098] This embodiment is based on Embodiment 1, but differs in that the fixing plate in this embodiment only includes the back plate, and the comb-tooth structure is disposed on the back plate. The fixing plate can be connected to the support side plate and the terminal module via the comb-tooth structure. During the press-fitting process, the support side plate can be directly subjected to pressure, as well as pressure transmitted from the terminal module. After the fisheye press-fitting of the terminal module is in place, the support side plate can promptly support the printed circuit board, preventing the terminal module from being damaged by excessive pressure.

[0099] Specific embodiment 11 of the connector provided by this utility model:

[0100] This embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that the pressure-bearing limiting component in this embodiment is a frame structure. The longitudinal side frames of the pressure-bearing limiting component are used to cooperate with the printed circuit board and the fixing plate, respectively.
