Description

Technical Field

[0001] This disclosure relates to the technical field of electrical connector assemblies, and in particular to a backplane structure and an electrical connector assembly. Background Technology

[0002] In electrical connector assemblies, the backplane structure is one of the important structures. The backplane structure is mounted and fixed on the circuit board to improve the structural strength of the circuit board.

[0003] Related technologies, such as patent CN201252192Y, disclose an electrical connector assembly, which includes an electrical connector assembled on top of a circuit board and a backplate assembled below the circuit board. The upper surface of the backplate is coated with a high-temperature resistant insulating material to isolate the circuit board and the backplate. The aforementioned electrical connector assembly has good insulation performance and is easy to assemble.

[0004] However, the backplate of the aforementioned electrical connector assembly requires corresponding clearance holes to be made according to the location of the capacitors on the circuit board so that the capacitors on the circuit board can be accommodated in the clearance holes. This makes the backplate difficult to process and manufacture, which in turn greatly increases the production difficulty of the electrical connector assembly. At the same time, it also greatly reduces the structural strength of the backplate, thereby reducing the structural strength of the electrical connector assembly. This makes the circuit board more prone to deformation when the electrical connector assembly is subjected to large external forces, which in turn leads to unstable contact between the conductive terminals of the circuit board and the chip, greatly reducing the stability of the electrical connector assembly in use. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a backplane structure and electrical connector assembly that are easier to manufacture and have better stability in use.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] A backplane structure includes a fixing plate for mounting a circuit board; the backplane structure further includes a support member disposed between the circuit board and the fixing plate to form a capacitor clearance area between the circuit board and the fixing plate, the capacitor clearance area being used to accommodate the capacitor of the circuit board; one end of the support member is fixed to the fixing plate, and the other end of the support member is used to support the chip mounting portion of the circuit board.

[0008] In one embodiment, the support member is disposed opposite to the chip mounting portion of the circuit board, so that the support member is used to support the chip mounting portion of the circuit board.

[0009] In one embodiment, the thickness of the support member ranges from 0.4 mm to 1.2 mm.

[0010] In one embodiment, the support member is welded and fixed to the fixing plate.

[0011] In one embodiment, the cross-sectional area of ​​the support member is greater than or equal to the cross-sectional area of ​​the chip mounting portion of the circuit board.

[0012] In one embodiment, the cross-sectional area of ​​the support member is smaller than the cross-sectional area of ​​the fixing plate.

[0013] In one embodiment, the backplate structure further includes an insulating sheet disposed between the circuit board and the support member.

[0014] In one embodiment, the insulating sheet is attached to the support member.

[0015] An electrical connector assembly includes a circuit board and a backplate structure as described in any of the above embodiments, wherein a support member is disposed between the circuit board and the fixing plate, and both ends of the support member are respectively supported on the circuit board and the fixing plate.

[0016] In one embodiment, the fixing plate is threaded to the circuit board.

[0017] In one embodiment, the electrical connector assembly further includes a fastener, the fixing plate has a positioning hole, the circuit board has a threaded hole opposite to the positioning hole, and the fastener passes through the positioning hole and is screwed into the threaded hole.

[0018] Compared with the prior art, this disclosure has at least the following advantages:

[0019] 1. In the aforementioned backplate structure, since the support member is positioned between the circuit board and the fixing plate, a capacitor clearance area is formed between the circuit board and the fixing plate. This capacitor clearance area is used to accommodate the capacitors of the circuit board. Compared with the backplate design of the electrical connector assembly in the aforementioned related technologies, the fixing plate of this disclosure does not need to open corresponding clearance holes according to the capacitor positions of the circuit board, which greatly reduces the processing and manufacturing difficulty of the fixing plate, thereby greatly reducing the production difficulty of the electrical connector assembly of this disclosure. At the same time, it also greatly improves the structural strength of the fixing plate, so that the fixing plate can effectively improve the overall rigidity of the fixing plate, thereby effectively reducing the possibility of deformation of the circuit board due to external forces, making the contact between the circuit board and the chip more uniform and stable, and thus greatly improving the stability of the electrical connector assembly of this disclosure.

[0020] 2. Since one end of the support is fixed to the fixing plate and the other end of the support is used to support the chip mounting part of the circuit board, the support can improve the overall rigidity of the chip mounting part of the circuit board, which greatly improves the structural strength of the chip mounting part of the circuit board. This effectively reduces the phenomenon of dent deformation of the chip mounting part of the circuit board due to external force, and makes the contact between the chip mounting part of the circuit board and the chip more uniform and stable, further improving the stability of the electrical connector assembly.

[0029] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0030] like Figures 1 to 4 As shown, a backplane structure 100 of one embodiment includes a fixing plate 110 for mounting a fixed circuit board 200. The backplane structure 100 also includes a support member 120 for being disposed between the circuit board 200 and the fixing plate 110, so that a capacitor clearance area (not shown) is formed between the circuit board 200 and the fixing plate 110. The capacitor clearance area is used to accommodate the capacitors of the circuit board 200. Compared with the backplane design of the electrical connector assembly in the above-mentioned related art, the fixing plate 110 of this disclosure does not need to open corresponding clearances according to the capacitor positions of the circuit board 200. The perforated holes greatly reduce the manufacturing difficulty of the fixing plate 110, thereby significantly reducing the production difficulty of the electrical connector assembly 10 of this disclosure. At the same time, they also greatly improve the structural strength of the fixing plate 110, enabling the fixing plate 110 to effectively improve its overall rigidity. This significantly increases the structural strength of the fixing plate 110, thereby effectively reducing the possibility of deformation of the circuit board 200 due to external forces. This makes the contact between the circuit board 200 and the chip more uniform and stable, and thus greatly improves the stability of the electrical connector assembly 10 of this disclosure in use.

[0031] like Figures 1 to 4 As shown, one end of the support member 120 is fixed to the fixing plate 110, and the other end of the support member 120 is used to support the chip mounting part of the circuit board 200, so that the support member 120 can improve the overall rigidity of the chip mounting part of the circuit board 200, thereby greatly improving the structural strength of the chip mounting part of the circuit board 200, effectively reducing the phenomenon of dent deformation of the chip mounting part of the circuit board 200 due to external force, and making the contact between the chip mounting part of the circuit board 200 and the chip more uniform and stable, further improving the stability of the use of the electrical connector assembly 10.

[0032] The backplate structure 100 described above, with the support member 120 disposed between the circuit board 200 and the fixing plate 110, forms a capacitor clearance area between the circuit board 200 and the fixing plate 110. The capacitor clearance area is used to accommodate the capacitors of the circuit board 200. Compared with the backplate design of the electrical connector assembly in the aforementioned related technologies, the fixing plate 110 of this disclosure does not need to open corresponding clearance holes according to the capacitor positions of the circuit board 200, which greatly reduces the processing and manufacturing difficulty of the fixing plate 110, thereby greatly reducing the production difficulty of the electrical connector assembly 10 of this disclosure. At the same time, it also greatly improves the structural strength of the fixing plate 110, so that the fixing plate 110 can effectively improve the overall rigidity of the fixing plate 110, thereby greatly improving the structural strength of the fixing plate 110, thereby effectively reducing the possibility of deformation of the circuit board 200 due to external forces, making the contact between the circuit board 200 and the chip more uniform and stable, and thus greatly improving the stability of the electrical connector assembly 10 of this disclosure.

[0033] Furthermore, since one end of the support member 120 is fixed to the fixing plate 110, and the other end of the support member 120 is used to support the chip mounting part of the circuit board 200, the support member 120 can improve the overall rigidity of the chip mounting part of the circuit board 200, thereby greatly improving the structural strength of the chip mounting part of the circuit board 200. This effectively reduces the phenomenon of dent deformation caused by external force on the chip mounting part of the circuit board 200, and makes the contact between the chip mounting part of the circuit board 200 and the chip more uniform and stable, further improving the stability of the electrical connector assembly 10.

[0034] like Figures 2 to 3 As shown, in this embodiment, the fixing plate 110 is a stainless steel plate or a steel plate, so that the fixing plate 110 has better structural strength, thereby further improving the structural strength of the circuit board 200, reducing the possibility of deformation of the circuit board 200 due to external force, and thus improving the stability of the use of the electrical connector assembly 10.

[0035] like Figure 3 As shown, in this embodiment, the support member 120 is a steel support member 120, so that the support member 120 has better structural strength, thereby further improving the structural strength of the chip mounting part of the circuit board 200, which greatly reduces the possibility of the chip mounting part of the circuit board 200 being dented and deformed due to external force, and further improves the stability of the high-voltage connector assembly 10.

[0036] like Figure 1As shown, in one embodiment, the support member 120 is disposed opposite to the chip mounting portion of the circuit board 200, so that the support member 120 supports the chip mounting portion of the circuit board 200, thereby greatly improving the structural strength of the chip mounting portion of the circuit board 200, and thus greatly reducing the possibility of the chip mounting portion of the circuit board 200 being dented or deformed due to external force, thereby improving the stability of the high-voltage connector assembly 10.

[0037] like Figure 3 As shown, in one embodiment, the thickness of the support member 120 ranges from 0.4mm to 1.2mm, so that the support member 120 has good structural strength, thereby improving the structural strength of the chip mounting portion of the circuit board 200, and also allowing the capacitor clearance area to have sufficient space to accommodate the capacitor of the circuit board 200.

[0038] like Figure 3 As shown, in one embodiment, the support member 120 is welded and fixed to the fixing plate 110 so that the support member 120 can be securely fixed to the fixing plate 110, avoiding the phenomenon that the support member 120 may loosen or even detach from the fixing plate 110 due to collision or other external factors, thereby greatly improving the stability of the use of the electrical connector assembly 10.

[0039] like Figure 3 As shown, in one embodiment, the cross-sectional area of ​​the support member 120 is greater than or equal to the cross-sectional area of ​​the chip mounting portion of the circuit board 200, so that the support member 120 can better support the chip mounting portion of the circuit board 200, thereby greatly improving the structural strength of the chip mounting portion of the circuit board 200 and effectively reducing the possibility of dent deformation of the chip mounting portion of the circuit board 200.

[0040] like Figure 3 As shown, in one embodiment, the cross-sectional area of ​​the support member 120 is smaller than the cross-sectional area of ​​the fixing plate 110, so that the capacitor clearance area has enough space to accommodate the capacitor of the circuit board 200.

[0041] like Figure 3 As shown, in one embodiment, the backplane structure 100 further includes an insulating sheet 130, which is disposed between the circuit board 200 and the support member 120 so that the insulating sheet 130 can electrically isolate the circuit board 200, prevent the fixing plate 110 from being charged, and thereby improve the safety of the use of the electrical connector assembly 10.

[0042] like Figure 3As shown, in one embodiment, the insulating sheet 130 is attached to the support member 120 so that the insulating sheet 130 can be fixed between the support member 120 and the circuit board 200, so as to prevent the insulating sheet 130 from becoming loose or even detaching from the back plate structure 100 due to external factors, and further improve the safety of the use of the electrical connector assembly 10.

[0043] like Figures 1 to 3 As shown, this disclosure also provides an electrical connector assembly 10, including a circuit board 200 and a backplate structure 100 as described in any of the above embodiments. A support member 120 is disposed between the circuit board 200 and the fixing plate 110, and the two ends of the support member 120 are respectively supported on the circuit board 200 and the fixing plate 110.

[0044] like Figures 1 to 3 As shown, in one embodiment, the fixing plate 110 is threaded to the circuit board 200 so that the fixing plate 110 can be securely fixed to the circuit board 200, avoiding the phenomenon that the fixing plate 110 may become loose or even detach from the circuit board 200 due to collision or other external factors. This greatly improves the stability of the electrical connector assembly 10 and also greatly reduces the difficulty of installing and disassembling the fixing plate 110, making the replacement of the fixing plate 110 much easier, thereby greatly improving the ease of use of the electrical connector assembly 10.

[0045] like Figures 1 to 3 As shown, in one embodiment, the electrical connector assembly 10 further includes a fastener 300. The fixing plate 110 has a positioning hole 111, and the circuit board 200 has a threaded hole (not shown) opposite to the positioning hole 111. The fastener 300 passes through the positioning hole 111 and is screwed into the threaded hole to facilitate the replacement of the fixing plate 110, which greatly reduces the difficulty of installing and disassembling the fixing plate 110, thereby greatly improving the ease of use of the electrical connector assembly 10.

[0046] Compared with the prior art, this disclosure has at least the following advantages:

[0047] 1. In the aforementioned electrical connector assembly 10, since the support member 120 is disposed between the circuit board 200 and the fixing plate 110, a capacitor clearance area is formed between the circuit board 200 and the fixing plate 110. The capacitor clearance area is used to accommodate the capacitor of the circuit board 200. Compared with the backplate design of the electrical connector assembly in the aforementioned related technologies, the fixing plate 110 of this disclosure does not need to open corresponding clearance holes according to the capacitor position of the circuit board 200, which greatly reduces the processing and manufacturing difficulty of the fixing plate 110, thereby greatly reducing the production difficulty of the electrical connector assembly 10 of this disclosure. At the same time, it also greatly improves the structural strength of the fixing plate 110, so that the fixing plate 110 can effectively improve the overall rigidity of the fixing plate 110, thereby greatly improving the structural strength of the fixing plate 110, thereby effectively reducing the possibility of deformation of the circuit board 200 due to external force, making the contact between the circuit board 200 and the chip more uniform and stable, thereby greatly improving the stability of the use of the electrical connector assembly 10 of this disclosure.

[0048] 2. Since one end of the support member 120 is fixed to the fixing plate 110, and the other end of the support member 120 is used to support the chip mounting part of the circuit board 200, the support member 120 can improve the overall rigidity of the chip mounting part of the circuit board 200, thereby greatly improving the structural strength of the chip mounting part of the circuit board 200. This effectively reduces the phenomenon of dent deformation caused by external force on the chip mounting part of the circuit board 200, and makes the contact between the chip mounting part of the circuit board 200 and the chip more uniform and stable, further improving the stability of the use of the electrical connector assembly 10.
