The connection structure of the IO module and the IO module Technical Field
[0001] This utility model belongs to the field of electrical connector technology, specifically relating to an improved connection structure on an I / O module, and an I / O module using this connection structure. Background Technology
[0002] In existing IO modules, the front connector and IO housing are connected by a rotating connection. In this connection, the pivot is located on the front connector, and the latch is located on the IO housing. Since the operator operates by rotating the front connector, improper force during operation may cause the front connector to detach abnormally from the IO housing.
[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention
[0004] The purpose of this invention is to provide an improved connection structure to solve the problem of abnormal detachment between the front connector and the IO housing on the IO module.
[0005] To achieve the above objectives, a specific embodiment of this utility model provides a connection structure for an IO module. The IO module includes a front connector and an IO housing. The connection structure includes a protrusion and two opposing mounting blocks. The mounting blocks are formed on the IO housing, and a rotating shaft connects the mounting blocks. An arc-shaped groove is formed on the inner side of one of the mounting blocks, and a slot communicating with the arc-shaped groove is also formed on the top wall of the mounting block. The radius of curvature of the arc-shaped groove is the same as the radius of curvature of the rotating shaft. The protrusion is formed on the front connector, and an arc-shaped abutment groove is provided on the protrusion. A positioning post is provided on the protrusion corresponding to the slot side, which is inserted into the slot or the arc-shaped groove.
[0006] In one or more embodiments of this utility model, the radius of curvature of the abutment groove is greater than or equal to the radius of curvature of the rotating shaft.
[0007] In one or more embodiments of this utility model, the positioning post is a cylindrical column whose cross-sectional diameter is the same as the width of the arc-shaped groove.
[0008] In one or more embodiments of this utility model, the distance between the two mounting blocks is the same as the length of the abutment groove.
[0009] In one or more embodiments of this utility model, the opening angle of the abutment groove is greater than or equal to 180°.
[0010] In one or more embodiments of the present invention, the slot is connected to one end of the arcuate groove.
[0011] In one or more embodiments of this utility model, the slot is arranged in a vertical direction.
[0012] In one or more embodiments of this utility model, the length of the arc-shaped groove is set such that when the front connector is rotated to be inserted into the IO housing, the positioning post moves to contact or not contact the end of the other end of the arc-shaped groove.
[0013] In one or more embodiments of this utility model, the arcuate groove extends to the side of the mounting block opposite to the other mounting block.
[0014] This utility model also provides an IO module, including a front connector and an IO housing, which are pivotally connected by the above-described connection structure.

[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0024] As shown in Figure 2, in one embodiment of this utility model, the connection structure on the IO module includes a front connector 10 and an IO housing 20. The specific connection structure includes a protrusion 11 and two mounting blocks 21. The two mounting blocks 21 are formed on the IO housing 20 and are arranged opposite to each other. A rotating shaft 22 connects the two mounting blocks 21. At least one of the mounting blocks 21 has an arc-shaped groove 211 on its inner side. A slot 212 communicating with the arc-shaped groove 211 is also formed on the top wall of the mounting block 21. The arc-shaped groove 211 and the rotating shaft 22 have the same radius of curvature. The protrusion 11 protrudes from the front connector 10 and has an arc-shaped abutment groove 111. A positioning post 112, which inserts into the slot 212 or the arc-shaped groove 211, is provided on the protrusion 11 on the side corresponding to the slot 212.
[0025] Since the arc groove 211 is connected to the outer wall of the mounting block 21 only through the slot 212, when installing the front connector 10, the positioning pin 112 needs to be inserted into the slot 212 until it enters the arc groove 211. Since the entire arc groove 211 surrounds the pivot 22, the entire front connector 10 can only rotate as the positioning pin 112 moves within the arc groove 211, so that the movement of the front connector 10 is a rotation with the pivot 21 as the center. Therefore, it can only be detached outward when the positioning pin 112 moves to the position of the slot 212, resulting in high stability.
[0026] To improve the stability of the connection between the front connector 10 and the IO housing 20, arc-shaped grooves 211 are provided on the inner side of both mounting blocks 21, and slots 212 communicating with each arc-shaped groove 211 are provided on the top of each block. Correspondingly, two positioning pins 112 are provided on the protrusion 11, which are inserted into the arc-shaped grooves 211 on the two mounting blocks 21 respectively, so as to provide limiting from both sides of the protrusion 11 and prevent the front connector 10 from shaking.
[0027] In one embodiment, to further improve the stability of the front connector 10 during rotation, the radius of curvature of the abutment groove 111 is greater than or equal to the radius of curvature of the rotating shaft 22, so that the rotating shaft 22 can completely fit against the groove wall of the abutment groove 111, and there is no gap between the rotating shaft 22 and the groove wall of the abutment groove 111. Furthermore, since the contact area between the two is much larger than the contact area between the positioning post 112 and the inner wall of the arc-shaped groove 211, most of the force between the front connector 10 and the IO housing 20 is borne by the rotating shaft 22 and the abutment groove 111, greatly reducing the force on the positioning post 112 and significantly lowering the probability of its breakage.
[0028] Preferably, the positioning post 112 is a cylindrical column with a cross-sectional diameter that is the same as (or slightly smaller than) the width of the arc groove 211. Therefore, the positioning post 112 always fits against the inner wall of the arc groove 211 when it moves, so that the front connector 10 will not wobble when it rotates, and the stability is higher.
[0029] Furthermore, the main body of the protrusion 11 is a rectangular structure, and the abutment groove 111 extends axially through its width. In order to improve the stability during rotation, the distance between the two mounting blocks 21 is the same as (or slightly larger than) the length of the abutment groove 111 (i.e., the width of the protrusion 11), so that the protrusion 11 always abuts against the two mounting blocks 11 when the front connector 10 rotates, thus preventing left and right wobbling and achieving high stability.
[0030] In one embodiment, the opening angle of the abutment groove 111 is greater than or equal to 180°, meaning that there is only a contact relationship between it and the rotating shaft 22, and no snap-fit relationship. This setting is suitable when the diameter of the abutment groove 111 is greater than or equal to the diameter of the rotating shaft 22. When the diameters are the same, the opening angle of the abutment groove 111 can be set to less than 180°. In this case, when installing the front connector 10, the rotating shaft 22 needs to be embedded in the abutment groove 111, and there is a snap-fit relationship between the two. Even if the front connector 10 is rotated to the position or angle where the positioning post 112 aligns with the slot 212, it still cannot be properly detached from the IO housing 20 without applying a certain force, thus avoiding abnormal detachment of the front connector 10 and achieving high stability.
[0031] In the embodiment shown in Figures 2-4, the slot 212 is connected to the end of one end of the arc groove 211, so that when the front connector 10 is removed outward, the front connector 10 can be removed simply by rotating it until the end of the arc groove 211 can no longer be rotated. This allows for blind operation without repeatedly adjusting the position of the front connector 10 or visually observing whether the positioning post 112 is aligned with the slot 212, reducing the operating cost for workers and improving ease of use.
[0032] In one embodiment, the slot 212 is arranged in a vertical direction. In this case, the posture of the front connector 10 when rotated to the removable state can be adjusted by adjusting the relative position of the positioning post 112 outside the abutment slot 111 (e.g., the middle or the edge of both sides) to achieve the most suitable angle for the operator.
[0033] In a preferred embodiment, the arc groove 211 extends to the side of the mounting block 21 opposite to the other side of the mounting block 21, that is, the entire arc groove 211 penetrates the entire mounting block 21 in its depth direction, so that the internal positioning post 112 can be observed from the outside, and in some extreme accidental situations, the positioning post 112 can be directly applied from the outer shell with a finer tool, which is more flexible.
[0034] It is understood that when the current connector 10 rotates to one end of the slot 212, it is in a removable state (as shown in Figure 4). As it rotates towards the other end of the arc-shaped groove 211, it gradually approaches the IO housing 20. The position of the other end of the arc-shaped groove 211, i.e., the length of the entire arc-shaped groove 211, is set such that when the current connector 10 rotates to be inserted into the IO housing 20, the positioning post 112 moves to contact the end of the other end of the arc-shaped groove 211, i.e., when the front connector 10 can no longer rotate, it is inserted into the IO housing 20. Of course, the position of this end of the arc-shaped groove 211 can also be appropriately extended, as long as it does not obstruct the insertion of the front connector 10 into the IO housing 20. This embodiment is not limited to this.
[0035] This application also provides an IO module 100, including a front connector 10 and an IO housing 20, which are connected by the aforementioned connection structure. When installing the front connector 10 onto the IO housing 20, the orientation of the front connector 10 is adjusted so that the abutment groove 111 faces the fitting shaft 22, while the positioning pin 112 is inserted into the slot 212 until it enters the arc-shaped groove 211. Then, the front connector 10 is rotated until it is fully inserted into the IO housing 20, thus completing the installation (as shown in Figure 3). When it is necessary to remove the front connector 10, it is rotated until the positioning pin 112 moves to one end of the slot 212 at the desired orientation and angle (as shown in Figure 4), and the front connector 10 is moved outward to remove it.
[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
