Description

Technical Field

[0001] This invention relates to the field of circuit board testing technology, and in particular to a connector testing device. Background Technology

[0002] As the requirements for transmission speed and data exchange volume of communication equipment such as switches and routers increase, thin metal plates with spring arms are used as grounding plates to connect to grounding terminals in high-density, small-space applications to improve the performance of such equipment. This reduces resonance and acts as a shield for signal channels. These grounding plates are generally installed on connectors located inside the equipment. During use, the connectors are plugged into the equipment to make the grounding plate connect with the pads on the packaging board in the equipment. This design can greatly improve the performance of the equipment, especially in terms of crosstalk. However, after the connector is plugged into the packaging board, some grounding plates may not make contact with the pads on the packaging board, causing a decrease in the performance of these high-speed signal channels and thus reducing the overall performance of the device. Summary of the Invention

[0003] This invention discloses a connector testing device for detecting whether the grounding spring is in complete contact with the solder pads of the packaging board.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This invention provides a connector testing device, comprising: a connector body, a testing component, and a sealing plate body;

[0006] The connector body has a first surface close to the cover plate body, and the first surface is provided with a plurality of elastic grounding tabs for contacting the cover plate body. The cover plate body is provided with a first pad corresponding to the plurality of elastic grounding tabs.

[0007] The detection assembly includes a first detection element, a second detection element, and a detection module. The detection module is used to detect whether the first detection element and the second detection element are connected. The first detection element is disposed on the connector body and protrudes from the first surface. The second detection element is disposed on the sealing plate body. The first detection element has a detection end close to the sealing plate body. The elastic grounding piece has a contact end close to the sealing plate body. The distance from the detection end to the second detection element is greater than the distance from the contact end to the first pad.

[0008] This application adds a first detection element, a second detection element, and a detection module for testing, and separates the first and second detection elements. That is, the first detection element is set on the connector body, and the second detection element can be set on the encapsulation plate body, or the first detection element can be set on the encapsulation plate body, and the second detection element can be set on the connector body. When it is necessary to test whether the connector body and the encapsulation plate body are fully installed, the operator only needs to monitor the signal feedback of the detection module to complete the test. In the above-mentioned testing process, the testing process can be directly fed back, which is simple and fast.

[0009] Furthermore, in this application, the distance from the detection end of the elastic grounding piece to the second detection element is greater than the distance from the contact end to the first pad. During installation, when the connector body is connected to the sealing plate body, the multiple elastic grounding pieces on the connector body first contact the sealing plate body. After the elastic grounding pieces contact the sealing plate body, the first detection element and the second detection element will then contact, thereby triggering the detection module. This effectively avoids the problem of one of the multiple grounding springs failing to connect, making the above detection process more accurate.

[0010] In some embodiments, the first detection element includes an electrical connection plate and two detection terminals, the detection terminals being disposed on the two detection terminals and located on the same plane of the two detection terminals, and the electrical connection plate being used to connect the two detection terminals in series.

[0011] In some embodiments, the second detection element includes two second pads, an electrical circuit, and a circuit detection point. The second pads correspond one-to-one with the detection terminals. The electrical circuit is used to connect the two second pads in series. The circuit detection point is located at both ends of the electrical circuit and is signal-connected to the detection module.

[0012] In some embodiments, there are multiple first detection elements, and the multiple detection terminals are arranged in a ring array along the elastic grounding plate, and each detection terminal in the first detection element corresponds one-to-one with the second pad.

[0013] In some embodiments, the distance between the detection end and the first surface is a first distance, and the distance between the contact end and the first surface is a second distance, wherein the first distance is less than the second distance.

[0014] In some embodiments, the detection terminal has a first shape, which is a U-shaped structure with an opening facing away from the sealing plate body, and the detection end is the top of the U-shaped structure.

[0015] In some embodiments, the detection terminal has a second shape, which is a U-shaped structure with an opening parallel to the sealing plate body, and the two ends of the U-shaped structure are provided with contact sections, and the detection end is the contact section close to the sealing plate body.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1-3 As shown, in a first aspect, the present invention provides a connector testing device, comprising: a connector body 1, a testing component, and a sealing plate body 4;

[0031] The connector body 1 has a first surface 11 close to the cover plate body 4. The first surface 11 is provided with a plurality of elastic grounding pieces 2 for contacting the cover plate body 4. The cover plate body 4 is provided with a first pad 41 corresponding to the plurality of elastic grounding pieces 2.

[0032] The detection assembly includes a first detection element 300, a second detection element 400, and a detection module 5. The detection module 5 is used to detect whether the first detection element 300 and the second detection element 400 are connected. The first detection element 300 is disposed on the connector body 1 and protrudes from the first surface 11. The second detection element 400 is disposed on the sealing plate body 4. The first detection element 300 has a detection end 32 close to the sealing plate body 4. The distance from the detection end 32 to the second detection element 400 is greater than the distance from the contact end 21 to the first solder pad 41.

[0033] This application adds a first detection element 300, a second detection element 400, and a detection module 5 for testing. The first detection element 300 and the second detection element 400 are separately configured; that is, the first detection element 300 can be mounted on the connector body 1, and the second detection element 400 can be mounted on the sealing plate body 4. When it is necessary to test whether the connector body 1 and the sealing plate body 4 are fully installed, the operator only needs to monitor the signal feedback from the detection module 5 to complete the test. In the above-mentioned testing process, the testing process can be directly fed back, which is simple and quick.

[0034] In addition, you can refer to Figure 2In this application, the distance from the detection end 32 of the elastic grounding piece 2 to the second detection element 400 is greater than the distance from the contact end 21 to the first solder pad 41. During the installation process, when the connector body 1 is connected to the sealing plate body 4, the multiple elastic grounding pieces 2 on the connector body 1 first contact the sealing plate body 4. After the elastic grounding pieces 2 contact the sealing plate body 4, the first detection element 300 and the second detection element 400 will then contact each other, and the detection module 5 will be triggered to perform detection. This effectively avoids the problem of one of the multiple grounding pieces failing to connect, making the above detection process more accurate.

[0035] One possible implementation method is to continue referencing... Figure 1 The first detection element 300 includes an electrical connection plate 31 and two detection terminals 3. Detection end 32 is disposed on the two detection terminals 3 and is located on the same plane as the two detection terminals 3. The electrical connection plate 31 is used to connect the two detection terminals 3 in series. In the above structure, this application will provide an electrical connection plate 31 for connecting the detection terminals 3 in series. During use, the detection terminals 3 need to contact the second detection element 400. If one of the detection terminals 3 cannot fully contact the second detection element 400, the detection module 5 cannot be triggered. As shown in the figure, the position of the detection terminal 3 is set at the corner of the connector body 1. This design allows the detection terminal 3 to have a larger detection range and can detect whether multiple elastic grounding pieces 2 are fully in contact with the sealing plate body 4, increasing the accuracy of the detection.

[0036] In one possible implementation, there are multiple first detection elements 300, and multiple detection terminals 3 are arranged in a ring array along the elastic grounding piece 2. Each detection terminal 3 in the first detection element 300 corresponds one-to-one with the second pad 42. In this application, there may be multiple first detection elements 300, wherein each first detection element 300 is provided with one or two detection terminals 3, and the detection terminals 3 are arranged in a ring array, thereby enabling accurate detection after the grounding spring is connected.

[0037] In one possible implementation, refer to Figure 2 The distance between the detection end 32 and the first surface 11 is the first distance h1. The elastic grounding piece 2 has a contact end 21 close to the sealing plate body 4. The distance between the contact end 21 and the first surface 11 is the second distance h2. The first distance h1 is less than the second distance h2. The height difference between the first distance h1 and the second distance h2 is denoted as H. H can satisfy the following range: 0.15mm≤H≤0.80mm.

[0038] At the same time, when the second pad 42 is disposed on the sealing plate body 4, the height of the second pad 42 can be regarded as being flush with the height of the electrical circuit 43 of the sealing plate body 4, that is, the plane where the second pad 42 is located and the plane where the electrical circuit 43 is located are in the same plane, so as to ensure that the distance from the detection terminal 3 to the second pad 42 is greater than the distance from the elastic grounding piece 2 to the first pad 41, and when the elastic grounding piece 2 moves in a direction perpendicular to the first surface 11, the maximum movement distance thereof is H. Within this range, the elastic grounding piece 2 can completely contact the first pad 41 on the sealing plate body 4, thereby making the detection process more accurate.

[0039] In a possible implementation manner, referring to Figure 3 , the second detection member 400 includes two second pads 42, an electrical circuit 43 and a circuit detection point 44. The second pads 42 correspond to the detection terminals 3 one by one. The electrical circuit 43 is used to connect the two second pads 42 in series. The circuit detection points 44 are disposed at both ends of the electrical circuit 43 and are signal-connected to the detection module 5. In the above structure, during the detection process, the arrow in the figure is only a schematic diagram of the current direction in this application. The current enters the electrical circuit 43 from one of the circuit detection points 44. At this time, the current will be transmitted along the direction of the second pad 42 - detection terminal 3 - electrical connection plate 31 - electrical circuit 4 - the other circuit detection point 44. When the current reaches the other circuit detection point 44, the detection module 5 can detect whether the electrical circuit 43 is connected, and then transmit the connection signal, so as to more accurately and intuitively detect whether the grounding elastic piece realizes complete contact.

[0040] In a possible implementation manner, referring to Figure 4 , the shape of the detection terminal 3 is a first shape, and the first shape is a U-shaped structure with an opening facing away from the sealing plate body 4. The detection end 32 is the top of the U-shaped structure. In the above structure, the shape of the detection terminal 3 can be changed according to actual requirements. Specifically, as shown in the figure, the detection terminal 3 in the figure is a U-shaped structure with an opening facing away from the sealing plate body 4. At this time, the detection end 32 is the top of the U-shaped structure and is used to contact the second pad 42. The volume of this detection terminal 3 is small, and the space can be effectively utilized.

[0041] In a possible implementation manner, referring to Figure 5 , the shape of the detection terminal 3 is a second shape, and the second shape is a U-shaped structure with an opening parallel to the sealing plate body 4, and contact segments are provided at both ends of the U-shaped structure. The detection end 32 is the contact segment close to the sealing plate body 4. In the above structure, the second shape of the detection terminal 3 can also be regarded as a "ji" - shaped structure, where the protruding part of the "ji" - shaped structure serves as the detection end 32 in the second shape. In the above structure, the detection end 32 of the detection terminal 3 with the second shape can more accurately locate the detection point.

[0042] In one possible implementation, refer to Figure 6 The connector body 1 includes a housing body 12, which has a side surface connected to the first surface 11. When the detection terminal 3 is in the first shape, the electrical connection plate 31 is disposed on the side surface. Figure 1 The installation method shown is only one of the installation methods in this application. In this structure, the detection terminal 3 is bent.

[0043] In one possible implementation, refer to Figure 7 When the detection terminal 3 is in the second shape, the electrical connection plate 31 is disposed on the side. In the above structure, the electrical connection plate 31 is disposed on the side, so that the detection terminal 3 fits against the side, so that the detection terminal 3 can be used in different application environments. In this structure, the detection terminal 3 is a shell type.

[0044] In one possible implementation, refer to Figure 8 When the detection terminal 3 is in the second shape, the electrical connection plate 31 is disposed inside the housing body 12. In the above structure, the specific installation method of the detection terminal 3 is shown in the figure. In this structure, the detection terminal 3 is a blanking type.

[0045] In one possible implementation, refer to Figure 9 , Figure 9 This indicates another shape of the detection terminal 3, wherein the shape of the detection terminal 3 is the first shape, and the electrical connection plate 31 is disposed on the side, and the detection terminal 3 is attached to the side, so that the shape of the detection terminal 3 in this application can be changed according to actual needs.

[0046] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
