[0037] Embodiment one
[0038] Please refer to Figure 1 The utility model circuit board includes: circuit board component 1, both sides of circuit board component 1 are provided with the plug-in board 2, the plug-in board 2 is used to the extension of circuit board component 1 side, to make circuit board component 1 side protruding component far away from test frame, in the daily operation of circuit board, especially the scene that pulling action is more frequent, side protruding component is extremely easy to contact with test frame accidentally, by the ingenious setting plug-in board 2, the distance between circuit board component 1 side and test frame is effectively extended, thereby the probability that protruding component suffers collision in the pulling process is reduced in the root, this not only can avoid the physical damage of component caused by collision, such as pin bending, shell rupture and other problems.
[0039] Further, as shown in Figure 1 The plug-in board 2 and the side of the circuit board component 1 are connected with a plurality of second connection points 201, and the plurality of second connection points 201 are connected between the plug-in board 2 and the circuit board component 1 to realize the connection between the plug-in board 2 and the circuit board component 1.
[0040] Embodiment two
[0041] Further, as shown in Figure 1 The circuit board component 1 includes a plurality of circuit board bodies 101, and the plurality of circuit board bodies 101 are located between the two plug-in boards 2, and the second connection points 201 are connected between the plug-in boards 2 and the circuit board bodies 101. Compared with the design of a traditional single circuit board, the application adopts the design that a plurality of circuit board bodies 101 are connected together, that is, a panel structure is formed. The panel structure has many advantages. First, compared with the traditional single circuit board pulling operation, the panel design greatly reduces the pulling frequency. The reduction of the pulling frequency directly means that the risk of collision is reduced. This not only effectively protects various components on the circuit board from collision damage and reduces the scrap rate caused by physical damage, but also reduces the cost of manpower, material resources and time consumed in handling collision accidents. Second, in the aging test link, the panel structure greatly increases the number of circuit boards that can be processed at a time. In the same time period, more products can be aged and tested. This can significantly shorten the test period of products, speed up the pace of product listing, seize market opportunities, improve the utilization rate of test equipment and human resources, and improve the production efficiency and economic benefit of enterprises as a whole, and enhance the competitiveness of enterprises in the market.
[0042] Further, as shown in Figure 1As shown, the first connecting points 102 are connected between the adjacent circuit board bodies 101, and the first connecting points 102 are used to realize the connection between the circuit board bodies 101. The existence of the plurality of first connecting points 102 builds a connection bridge between the adjacent two circuit board bodies 101, so as to realize the connection between the adjacent circuit board bodies 101.
[0043] Embodiment three
[0044] Please refer to Figures 2-5 An aging test rack for aging test of a circuit board comprises two first support plates 302, and a plurality of limiting pieces are arranged between the two first support plates 302. The limiting pieces are used for limiting the circuit board, and the circuit board is vertically inserted into the limiting pieces. The limiting pieces play a crucial role in the aging test rack. During the aging test of the circuit board, the test environment is often complex, and various factors that may cause displacement or shaking of the circuit board exist. By limiting the circuit board through the limiting pieces, the circuit board can be firmly fixed at a predetermined position, effectively reducing a series of problems caused by shaking and displacement, thereby ensuring the high accuracy and reliability of the test results, enabling the test data to truly and effectively reflect the performance status of the circuit board, which has extremely important significance for accurately evaluating the quality of the circuit board, discovering potential defects, and optimizing product design, and provides reliable data support for product quality control and technical improvement.
[0045] Further, as shown in Figure 4 and Figure 5 The limiting piece comprises two limiting strips 4, and the two limiting strips 4 are fixedly installed on one side of the two first support plates 302 close to each other. The two limiting strips 4 are symmetrically arranged above and below each other, and the two limiting strips 4 are provided with limiting clamping grooves 401 on the side close to each other. The insertion plate 2 is inserted into the limiting clamping grooves 401. Compared with the prior art, the aging test is changed from the original "drawer type" circuit board insertion slot to the upper and lower clamping groove structure. This change greatly simplifies the operation process, and the operator only needs to simply insert or take out the circuit board, thereby greatly reducing the operation difficulty and time cost.
[0046] Further, as shown in Figure 4As shown, the front of the limiting strip 4 is provided with a guide opening 402, which is in communication with the limiting clamping groove 401. The guide opening 402 can guide the insertion of the plug-in plate 2 into the limiting clamping groove 401, facilitating the insertion of the plug-in plate 2 into the limiting clamping groove 401. Without the guide opening 402, the operator needs to use the naked eye and experience to accurately align the limiting clamping groove 401, which is not only difficult, but also prone to deviation, resulting in insertion failure or damage to the equipment. However, the presence of the guide opening 402 can guide the plug-in plate 2 to smoothly slide into the limiting clamping groove 401 when it approaches the limiting clamping groove 401, which not only improves the success rate of insertion, but also reduces the number of repeated operations due to insertion failure, thereby saving operation time and improving work efficiency.
[0047] Further, as shown in Figure 2 The two first support plates 302 are further provided with a plurality of rows of isolation support members, which are arranged between the plurality of limiting members. The isolation support members can isolate the plurality of limiting members.
[0048] Further, as shown in Figures 2-5 The row of isolation support members is composed of at least two isolation plates 3, the two ends of which are connected to the two first support plates 302. One of the isolation plates 3 is provided with a notch 301 on the front surface, which exposes the corresponding part of the circuit board body 101. This design provides an operating space for the operator when handling the circuit board, facilitating the operation and improving the convenience and efficiency of the handling operation, and reducing the operation time.
[0049] Further, as shown in Figure 2 The first support plate 302 is provided with an open mouth 303, and the second support plate 304 is arranged in the open mouth 303. The second support plate 304 is in contact with the limiting strip 4, which can provide additional support for the limiting strip 4, ensuring that the limiting strip 4 maintains good shape and position accuracy during long-term use, and can stably and reliably limit the circuit board.
[0050] In use, the circuit board is vertically inserted between the two limiting clamping grooves 401, so that the plug-in plate 2 is inserted into the limiting clamping groove 401, and the circuit board is placed. When taking out, pull the circuit board body 101 to separate the plug-in plate 2 from the limiting clamping groove 401, and the circuit board can be taken out.
[0051] Obviously, the above-described embodiments are only a part of the embodiments of the present application, rather than all the embodiments, and the preferred embodiments of the present application are given in the drawings, but do not limit the patent scope of the present application. The present application can be realized in many different forms, and conversely, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing specific embodiments, or equivalently replace some of the technical features.
