Figure 2, Figure 5 and Figure 6 It is shown that, by the connector provided by the embodiment of the present invention, the connector can be conveniently arranged according to the actual needs of the electronic device, and different oblique insertion angles can be adjusted according to different slot spacings. The larger the slot pitch, the board 2 The more space available on it. In a specific application, the circuit board 2 can be provided with one or two layers or multiple layers, and the tilt angle of the connector can be flexibly set according to the available space on the circuit board 2. For example, for boards with large slot spacing 2 . For example, the groove spacing h3 in Figure 6 is 1.7 inches. The connector body 1 can be flipped to an angle of 90 degrees to the board 2, and the connector body 1 is perpendicular to the board 2. The DIMM memory module 3 can be directly inserted into the connector body 1. The connector body 1 occupies the smallest planar area of the circuit board 2, so that the connector body 1 and the DIMM memory module 3 It can be densely arranged on the circuit board 2, so that the number of connectors that can be arranged per unit area is increased, which is advantageous for improving the performance of the electronic device and the expansion capability of the electronic device. For board 2 with a small slot spacing, for example Figure 6 When the groove spacing h2 is 1.5 inches and the groove spacing h2 is 1.2 inches, the connector body 1 can be flipped to an angle of less than 90 degrees to the board 2, and the connector body 1 It can be tilted relative to board 2. Moreover, the angle at which the connector body 1 is tilted can be adjusted according to the slot pitch. The smaller the slot pitch, the greater the inclination of the connector body 1, the connector body 1 and the circuit board 2 The smaller the angle between the two is; the larger the slot pitch is, the larger the angle between the connector body 1 and the circuit board 2 can be appropriately increased to reduce the connector body 1 occupying the circuit board 2 The area is beneficial to increase the density of the connector.

As shown in FIG. 6, the case where the connector of the embodiment of the present invention is applied to a single board having different slot pitches is shown. Standard DIMM memory 3 As an example, when the board 2 has a slot spacing of 1.2 inches, the connector body 1 can be adjusted to an angle of 25 degrees to the board 2. When board 2 has a slot pitch of 1.5 In inches, the connector body 1 can be adjusted to an angle of 45 degrees to board 2. When the slot spacing is 1.5 inches, it is not possible to use the memory stick in-line form if a fixed-angle beveled DIMM is used. For the connector, only 25 ° or 28.5 ° can be used, and the slot pitch space is not fully utilized; the angle of the connector body 1 can be adjusted to the angle of the connector body 1 by the angle adjustable connector provided by the embodiment of the present invention. 45 °, can meet the requirements of the oblique insertion height and make full use of the space of the groove spacing, and the memory strip layout density is higher than the 25 ° and 28.5 ° oblique insertion.
