Description

Technical Field

[0001] The utility model relates to the technical field of electronics, and in particular provides an electrical testing board for a fisheye pin connector. Background Art

[0002] like Figure 1 and Figure 2 As shown, when the electrical connector with high-density fisheye pins 102 plug-in terminals is configured on the PCB board 101 in a plug-in manner, the two sides 1021 of the fisheye pins 102 interfere with the terminal holes 1011 on the PCB board 101 through their own elasticity. After being adapted to the PCB board, it will basically not be removed. However, the electrical connector that has not been electrically tested has a high risk of defective rate when directly adapted to the PCB board due to the complex manufacturing process and high cost of high-density, high-precision fisheye pin electrical connectors. In the event that there are quality issues with the electrical connector itself and it is removed from the corresponding PCB board, it is necessary to consider whether the terminal holes of the PCB board can withstand the quality requirements of repeated insertion and removal, and also to consider the retention force of the fisheye pins of the terminals after repeated insertion and removal. In order to reduce quality risks, product testing is essential to ensure product yield. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a fisheye pin connector electrical testing board to solve the technical problem of electrical testing of high-density fisheye pin connectors.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A fisheye pin connector electrical testing board is provided for testing the electrical yield of electrical connectors. The electrical testing board includes a testing hole connected to a circuit and a wire spring disposed in the testing hole. During electrical testing of the connector, the end of the fisheye pin is inserted into the wire spring, so that the circuit of the testing board forms a path with the fisheye pin through the wire spring.

[0006] In this embodiment, preferably, the electrical testing board includes a plane adapted for the power supply connector and is provided with corresponding testing holes corresponding to the fisheye pins arranged on the electrical connector.

[0007] In this embodiment, it is preferred that the diameter of the detection hole is not less than the maximum width of the fisheye foot.

[0008] In this embodiment, it is preferred that the wire spring is not limited to being one of a crown spring, a lantern spring, a drum spring, a wrap spring, a bevel spring and a torsion spring.

[0009] In this embodiment, it is preferred that the wire spring includes a central hole or slot for the eye and foot ends to be inserted.

[0010] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0011] By enlarging the hole diameter for the fisheye pin to be inserted into the test board, the two sides of the fisheye pin are prevented from interfering with the hole wall of the test board, thereby avoiding interference deformation and ensuring product quality;

[0012] By adding spring wires to the holes in the test board so that the fisheye tip can contact and conduct, the electrical testing requirements of the product are met, unnecessary damage caused by product testing is effectively avoided, and product utilization is improved.

[0019] In the following description, specific details such as specific system structures and technologies are provided for illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obstructing the description of the present application with unnecessary details.

[0020] It will be understood that when used in this specification and the appended claims, the term "comprising" indicates the presence of described features, integers, steps, operations, elements and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or collections.

[0021] To simplify the drawings, only the parts relevant to the present invention are schematically shown in each figure. They do not represent the actual structure of the product. In addition, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one."

[0022] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0023] In the embodiments shown in the accompanying drawings, directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of various components of the present invention are not absolute but relative. These descriptions are applicable when these components are in the positions shown in the accompanying drawings. If the descriptions of the positions of these components are changed, these directional indications will also change accordingly.

[0024] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0026] See Figure 3 and Figure 4The figure discloses a fisheye pin connector electrical test board, the electrical test board 10 includes a detection hole 11 and a wire spring 12 arranged in the detection hole. In this example, the electrical test board 10 is based on (i.e., "equivalent to") a PCB board and has a circuit (not shown in the figure). The electrical test board (such as a PCB board) includes a plane adapted for the power supply connector. The detection hole corresponds to the corresponding fisheye pin arranged on the electrical connector. The detection hole 11 is based on the plug hole arranged (or called an "array") on the PCB board and connected to the circuit. The difference between the detection hole 11 and the plug hole is that the detection hole is larger than the diameter of the plug hole. For example, when the fisheye pin is inserted into the plug hole, it is necessary to ensure that the interference is effectively electrically conductive. Usually, the diameter of the plug hole is 0.1mm-0.14mm smaller than the maximum width of the fisheye pin. However, when the fisheye pin is inserted into the detection hole, the standard is that both are not damaged due to friction. This requires that the diameter of the detection hole is not less than the maximum width of the fisheye pin. In this example, the wire spring 12 is not limited to being one of a crown spring, a lantern spring, a drum spring, a wrap spring, an oblique spring and a torsion spring, and includes a center hole (not shown) or a gap (not shown) for a pin (or the "tip" at the end of the fisheye pin) to be plugged into, so that the tip is effectively electrically connected to the wire spring. Due to the interference between the wire spring and the detection hole, the circuit connected to the fisheye pin of the connector being tested and the detection hole is connected, thereby ensuring the effectiveness of the product electrical testing.

[0027] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0028] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
