Description

Technical Field

[0001] This utility model relates to an electrical connector assembly, and more particularly to an electrical connector assembly with a double-sided mounting plate. Background Technology

[0002] In existing electrical connector assemblies, a common mating method involves the interlocking of the paddle card in the plug (e.g., OSFP) with the flexible terminals in the socket. The terminals overlap in the gold finger area, thereby achieving electrical connection. However, this mating method has the following drawbacks:

[0003] Disadvantage 1: The panel is inserted gradually in a horizontal direction before it makes full contact with the elastic terminal in the socket, which can easily lead to pin failure and damage to the elastic structure.

[0004] Disadvantage 2: Because the terminals of the socket need to be inserted into guides, stubs are eventually formed. However, stubs reduce signal integrity (SI) performance. The higher the signal frequency, the greater the impact.

[0005] Disadvantage 3: The mating method of the gold fingers is limited by size (it can only continue in the width direction, not increase in the length direction), so the number of channels that can be connected is limited, and high-density multi-channel mating cannot be performed at one time. Currently, the maximum number of mating channels in a single product application is 16 pairs.

[0006] In addition, there are other mating methods in existing electrical connector assemblies, but these mating methods often lead to complex mating structures, excessively long connection lines, numerous conversions, greater energy loss, and higher SI insertion loss. Utility Model Content

[0007] This utility model was developed to solve the above-mentioned technical problems and other potential technical problems.

[0008] One aspect of this utility model provides an electrical connector assembly, including a first component, a second component, and a third component. A generally flat plate is disposed at one end of the first component, and a plurality of electrical contacts are disposed on the surface of the plate. A plurality of electrical contacts are also disposed on the surfaces of the second and third components. The plurality of electrical contacts disposed on the surface of the plate are respectively disposed on two surfaces of the plate opposite in the thickness direction. The second and third components abut against the two surfaces of the plate opposite in the thickness direction, such that the plurality of electrical contacts on the surface of the second component respectively contact corresponding electrical contacts on one surface of the plate, and the plurality of electrical contacts on the surface of the third component respectively contact corresponding electrical contacts on the other surface of the plate.

[0009] Optionally, the plurality of electrical contacts disposed on the surface of the plate are rigid electrical contacts, while the plurality of electrical contacts disposed on the surfaces of the second component and the third component are resilient electrical contacts. Alternatively, the plurality of electrical contacts disposed on the surface of the plate are resilient electrical contacts, while the plurality of electrical contacts disposed on the surfaces of the second component and the third component are rigid electrical contacts.

[0010] Preferably, the electrical connector assembly further includes a biasing component that biases the second and third components toward the first component, such that the second and third components clamp the mounting plate in the thickness direction. Optionally, the biasing component is a spring or an elastic cage.

[0011] Optionally, a gap exists between the second and third components, into which the patch can be inserted, and the size of the gap is adjustable in the thickness direction. Specifically, before the patch is inserted into the gap, the gap is widened to allow the first component to be smoothly inserted. After the patch is fully inserted into the gap, the gap is narrowed to clamp the patch.

[0012] Optionally, the plurality of electrical contacts on the two opposite surfaces of the plate, the plurality of electrical contacts on the surface of the second component, and the plurality of electrical contacts on the surface of the third component are arranged in a matrix distribution.

[0013] Optionally, the first component is an electrical plug, and the second and third components are optical terminal boxes.

[0014] Another aspect of this invention provides a pluggable electrical connector suitable for transmitting electrical energy and / or signals, the electrical connector comprising the electrical connector assembly according to the preceding aspect.

[0015] By adopting the technical solution of this utility model, the following beneficial effects can be obtained:

[0016] 1. It simplifies the combination of system links, shortens circuit length, and reduces energy loss.

[0017] 2. The first, second, and third components are press-fitted together using double-sided panels, doubling the number of channels. The interface has been changed from linear contact via gold fingers to point-to-point surface contact, achieving a cumulative length and high-density connection.

[0018] 3. The first, second, and third components are pressed together vertically, forming a double-sided fit. Compared to a conventional single-sided fit, this increases the fit area at individual points while maintaining the same quantity, thus improving the success rate of the fit.

[0019] 4. The first, second, and third components are in surface contact when they are joined together, which can simultaneously increase the number of points in both the width and length (XY) directions to achieve high-density connections.

[0020] 5. The electrical contacts adopt a point-type connection method, which solves the problem of residual wires generated by the previous flexible terminals and improves SI performance.

[0021] 6. The first, second, and third components are pressed together, forming a double-sided fit. Compared to the conventional single-sided fit, the product experiences more uniform stress and is largely free from the adverse effects of the insertion direction of the mounting plate, thus avoiding pin collapse and damage to the elastic structure.

[0031] like Figures 1A to 2D As shown, the electrical connector assembly 100 according to this utility model includes a first component 1, a second component 2, and a third component 3. The first component 1 includes a body 11. A generally flat plate 12 is provided at one end of the body 11, and a lead wire 13 is provided at the other end of the body 11. The lead wire 13 passes through the body 11 and is connected to the plate 12.

[0032] The second component 2 includes a main body 21 and a lead wire 23. The third component 3 includes a main body 31 and a lead wire 33. Multiple electrical contacts 14 and 15 are provided on the surface of the mounting plate 12, and multiple electrical contacts 22 and 32 are provided on the surfaces of the second component 2 and the third component 3. The multiple electrical contacts 14 and 15 on the surface of the mounting plate 12 are respectively located on two opposite surfaces of the mounting plate 12 (the upper and lower surfaces in the figure). The second component 2 and the third component 3 abut against the two opposite surfaces of the mounting plate 12, such that the multiple electrical contacts 22 on the surface of the second component 2 respectively contact the corresponding electrical contacts 14 on one surface of the mounting plate 12, and the multiple electrical contacts 32 on the surface of the third component 3 respectively contact the corresponding electrical contacts 15 on the other surface of the mounting plate 12, as shown below. Figure 1C As shown.

[0033] Optionally, the plurality of electrical contacts 14 and 15 disposed on the surface of the mounting plate 12 are rigid electrical contacts, while the plurality of electrical contacts 22 and 32 disposed on the surfaces of the second component 2 and the third component 3 are elastic electrical contacts. The electrical contacts are in the form of very small circles or rectangles, such as... Figure 2C and Figure 2D As shown.

[0034] like Figure 2B , Figure 2C and Figure 2BAs shown, the second component 2 and the third component 3 are spaced apart from each other in the thickness direction, thereby forming a gap S between the second component 2 and the third component 3. The distance of the gap S in the thickness direction is adjustable by means of a control mechanism mentioned below, i.e., the distance can be increased or decreased.

[0035] The electrical connector assembly 100 may further include a biasing component (not shown) and its control mechanism (not shown). The biasing component biases the second component 2 and the third component 3 toward the first component 1 (correspondingly, the gap S is reduced in the thickness direction), such that the second component 2 and the third component 3 clamp the mounting plate 12. Multiple electrical contacts 14, 15 on opposite surfaces of the mounting plate 12, multiple electrical contacts 22 on the surface of the second component 2, and multiple electrical contacts 32 on the surface of the third component 3 may be arranged in a matrix distribution, such as... Figures 2A to 2D As shown.

[0036] Preferably, during the insertion of the plate 12 of the first component 1 into the gap S and before it makes full contact with the multiple electrical contacts on the surfaces of the second component 2 and the third component 3, the biasing component is operated to control the biasing component so that the biasing component does not apply pressure to the second component 2 and the third component 3 or applies only a very small pressure, so that the gap S is kept relatively large in the thickness direction. This helps the plate 12 to be smoothly inserted into the gap S and avoids the multiple electrical contacts on the surface of the plate 12 from scratching or bumping with the multiple electrical contacts on the surfaces of the second component 2 and the third component 3.

[0037] Then, after the plate 12 is inserted into the gap S and reaches the desired position, the biasing component's control mechanism is operated to bias the second component 2 and the third component 3 toward the first component 1 (correspondingly, the distance of the gap S in the thickness direction decreases), causing the second component 2 and the third component 3 to clamp the plate 12. As a result, the plurality of electrical contacts on the surface of the plate 12 achieve complete contact with the plurality of electrical contacts on the surfaces of the second component 2 and the third component 3.

[0038] Alternatively, the biasing component is a spring or a flexible cage. Additionally, the control mechanism for the biasing component can be a control mechanism already existing in the art, such as the automatic latching / locking mechanism commonly used in pluggable electrical connectors, the details of which are omitted here.

[0039] By adopting the above technical solution, the product can be subjected to more uniform force and is no longer subject to the adverse effects of the insertion direction of the mounting plate, thus avoiding pin collapse and damage to the elastic structure.

[0040] Optionally, the first component 1 is an electrical plug, and the second component 2 and the third component 3 are optical terminal boxes (OTBs).

[0041] It can be seen that the second component 2 and the third component 3 can together form an electrical socket, although they are shown as separate components in the accompanying drawings.

[0042] It is conceivable that the electrical connector assembly 100 of this invention is suitable for pluggable electrical connectors for transmitting electrical energy and / or signals.

[0043] By adopting the technical solution of this utility model, the following beneficial effects can be obtained:

[0044] 1. It simplifies the combination of system links, shortens circuit length, and reduces energy loss.

[0045] 2. The first component 1, the second component 2, and the third component 3 are pressed together vertically, using a double-sided panel 12, doubling the number of channels. The interface is changed from linear contact via gold fingers to point-to-point surface contact, achieving a superposition of channels along the length direction and realizing high-density connections.

[0046] 3. The first component 1, the second component 2, and the third component 3 are pressed together vertically, forming a double-sided fit. Compared with the conventional single-sided fit, this increases the fit area at a single point while keeping the number of components constant, thus improving the success rate of the fit.

[0047] 4. The first component 1, the second component 2, and the third component 3 are in surface contact when they are fitted together, which can simultaneously increase the number of points in both the width and length (XY) directions to achieve high-density connection.

[0048] 5. The electrical contacts adopt a point-type connection method, which solves the problem of residual wires generated by the previous flexible terminals and improves SI performance.

[0049] 6. The first component 1, the second component 2, and the third component 3 are pressed together vertically, forming a double-sided fit. Compared with the conventional single-sided fit, the product is subjected to more uniform force and is basically no longer affected by the insertion direction of the mounting plate, thereby avoiding pin collapse and damage to the elastic structure.

[0050] Although the technical objectives, solutions, and effects of this utility model have been described in detail above with reference to specific embodiments, it should be understood that the above embodiments are merely exemplary and not restrictive. Any modifications, equivalent substitutions, or improvements made by those skilled in the art within the essential spirit and principles of this utility model are included within the protection scope of this utility model.
