Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to an improved connection structure and an IO module using the connection structure. Background Technology

[0002] In existing IO modules, the front connector and IO housing are connected by a rotating connection. In this connection method, the pivot is set on the front connector and the clip is set on the IO housing. Since the operator operates by rotating the front connector, the pivot is rotated directly, which can easily cause the front connector and IO housing to detach.

[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. Utility Model Content

[0004] The purpose of this invention is to provide a connection structure for use in connectors to solve the problem of easy detachment between the two parts of a connector.

[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 connecting part and a rotating shaft. The connecting part is disposed on the front connector and includes an arc-shaped abutment groove and an open circular snap-fit ​​groove adjacent to the abutment groove. The rotating shaft is disposed on the IO housing, and its diameter is smaller than the diameter of the snap-fit ​​groove but larger than the distance between its two open ends. The rotating shaft is configured to fit against the inner wall of the abutment groove while abutting against the open end of the snap-fit ​​groove.

[0006] In one or more embodiments of this utility model, the connecting portion is provided with one abutment groove and two snap-fit ​​grooves respectively provided on both sides of the abutment groove.

[0007] In one or more embodiments of this utility model, the connection structure includes two clamping plates protruding from the surface of the front connector and arranged opposite to each other, and two snap-fit ​​grooves are respectively opened on the two clamping plates, the spacing between the clamping plates being the same as the length of the rotating shaft.

[0008] In one or more embodiments of this utility model, the clamp is provided with an arc-shaped first guide surface, which is located on the side walls on both sides of the snap-fit ​​groove opening.

[0009] In one or more embodiments of the present invention, the connection structure further includes a protrusion protruding from the surface of the front connector and disposed between the two clamping plates, and the abutment groove is recessed on the protrusion.

[0010] In one or more embodiments of this utility model, the protrusion may or may not contact the clamps on both sides.

[0011] In one or more embodiments of this utility model, a rib protrudes from the outer wall of the rotating shaft, which abuts against the protrusion when the front connector rotates to a certain angle.

[0012] In one or more embodiments of this utility model, the protrusion is provided with an arc-shaped second guide surface, which is located on the sidewalls on both sides of the opening of the abutment groove.

[0013] In one or more embodiments of this utility model, the diameter of the abutment groove is greater than or equal to the diameter of the rotating shaft, and / or the openings of the abutment groove and the snap-fit ​​groove face the same direction.

[0014] This utility model also provides an IO module, including a front connector, an IO housing, and the above-described connection structure, wherein the IO housing and the front connector are pivotally connected through the above-described connection structure.

[0015] Compared with the prior art, the connection structure of this utility model sets the rotating shaft on the IO housing, while the abutment groove and the snap-fit ​​groove are opened on the front connector.

[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] like Figure 3-4 As shown, the connection structure in one embodiment of this utility model is mainly used on an IO module. The IO module includes a front connector 10 and an IO housing 20. The connection structure includes a connection portion 11 disposed on the front connector 10 and a rotating shaft 21 disposed on the IO housing 20. The connection portion 11 includes an arc-shaped abutment groove 111 and a snap-fit ​​groove 112 adjacent to the abutment groove 111. The diameter L1 of the snap-fit ​​groove 112 is larger than the diameter L2 of the rotating shaft 21, while its opening distance L3 is smaller than the diameter of the rotating shaft 21. The rotating shaft 21 simultaneously fits against the inner wall of the abutment groove 111 and the opening end of the snap-fit ​​groove 112.

[0025] In this embodiment, the rotating shaft 21 is disposed on the IO housing 20, and the connecting part 11, which consists of the abutment groove 111 and the snap-fit ​​groove 112, is disposed on the front connector 10. Therefore, during operation, the abutment groove 111 and the snap-fit ​​groove 112 are rotated, rather than the rotating shaft 21 is rotated directly. As a result, the force generated is smaller, making it difficult for the front connector 10 to detach from the IO housing 20.

[0026] Secondly, such as Figure 4 As shown, since the diameter of the snap-fit ​​groove 112 is larger and the opening is smaller (compared to the rotating shaft 21), and it is not concentric with the abutment groove 111, when the rotating shaft 21 abuts against the inner wall of the abutment groove 111, both ends are only snapped by the opening end of the snap-fit ​​groove 112, and do not abut against the inner wall of the snap-fit ​​groove 112. Therefore, the rotating shaft 21 is mainly supported by the abutment groove 111, while the snap-fit ​​groove 112 mainly provides a limit for the rotating shaft 21 to prevent it from disengaging from the abutment groove 111. Therefore, it is subjected to less force, which further reduces the probability of the front connector 10 disengaging from the IO housing 20.

[0027] Specifically, a snap-fit ​​groove 112 can be provided on the front connector 10, and an abutment groove 111 can be provided on both sides of the snap-fit ​​groove 112. This arrangement allows the middle position of the rotating shaft 21 to be limited by the snap-fit ​​groove 112, while the sides are supported by the abutment grooves 111. The front connector 10 cannot easily detach from the IO housing 20, and it will not wobble under the action of the abutment grooves 111 on both sides.

[0028] To improve stability, the front connector 10 can also be adopted. Figure 3 The configuration in this embodiment, where there is one abutment groove 111 and abutment grooves on both sides of the abutment groove 111, increases the number of limiting positions of the rotating shaft 21 and improves the connection effect. In this embodiment, the connection structure 11 includes two clamping plates 113 protruding from the surface of the front connector 10 and arranged opposite to each other. The two clamping plates 113 are arranged opposite to each other, and two snap-fit ​​grooves 112 are respectively formed on the two clamping plates 113. Two mounting blocks 22 are provided on the IO housing 20, and the rotating shaft 21 is connected between the two mounting blocks 22.

[0029] Since the snap-fit ​​groove 112 is located on both sides of the abutment groove 111, the two clamping plates 113 are located at the outermost periphery of the entire connecting part 11. To prevent the front connector 10 from moving left and right, the distance between the two clamping plates 113 is set to be the same as the length of the rotating shaft 21 (i.e., the distance between the two mounting blocks 22), so that the connecting part 11 is confined between the two mounting blocks 22 and will not move left and right when rotating, thus improving stability.

[0030] like Figure 3 As shown, the connection structure 11 also includes a protrusion 114 protruding from the surface of the front connector 10. The protrusion 114 is located between the two clamping plates 113, and an abutment groove 111 is formed on the protrusion 114. Therefore, by simply providing the protrusion 114 and the clamping plates 113 on the front connector 10, the space of the front connector 10 in the length or width direction can be greatly saved, providing customers with more convenience in arranging other devices on the IO module.

[0031] In such Figure 1-3 In the illustrated embodiment, the protrusion 114 does not contact the clamping plates 113 on both sides, and there is a gap between them. Of course, the protrusion 114 can also be configured to contact the clamping plates 113, that is, the protrusion 114 and the clamping plates 113 are integrally formed, and this embodiment is not limited thereto.

[0032] Preferably, a rib 23 protrudes from the outer wall of the rotating shaft 21. When the front connector 10 rotates to a certain angle, it abuts against the protrusion 114 to prevent the front connector 10 from continuing to rotate. The rib 23 is used to limit the rotation angle of the front connector 10. By setting the rib 23 in a suitable position, the front connector 10 can abut against the rib 23 after rotating to the limit angle and maintain that position. Without the rib 23, the front connector 10 needs to be held by the operator, or it will rotate outward to abut against the other side of the IO housing 20 when not held, which may cause the front connector 10 to detach abnormally. Therefore, the ease of use and stability are improved.

[0033] In one embodiment, the diameter of the abutment groove 111 is greater than or equal to the diameter of the rotating shaft 21, so that the rotating shaft 21 can fit completely into the abutment groove 111 without gaps, thus avoiding the situation where the front connector 10 will cause displacement other than rotation due to excessive force during use due to gaps between the two, and the situation where the front connector 10 becomes loose due to wear after long-term use.

[0034] Preferably, the openings of the abutment groove 111 and the snap-fit ​​groove 112 face the same direction, so that the rotating shaft 21 can directly enter the abutment groove 111 after passing through the opening of the snap-fit ​​groove 112, avoiding contact with its side wall.

[0035] In such Figure 3 In the embodiment shown, the clamping plate 113 is provided with an arc-shaped first guide surface 1131, which is located on the side walls on both sides of the opening of the snap-fit ​​groove 112, so that the contact surface with the rotating shaft 21 is smoother and the contact surface is not too sharp, which would cause scratches and damage to the rotating shaft 21.

[0036] Similarly, the protrusion 114 is provided with an arc-shaped second guide surface 1141, which is located on the side walls on both sides of the opening of the abutment groove 111, so as to avoid scratching and damaging the rotating shaft 21 when the connector 10 is disassembled and assembled.

[0037] This application also provides an IO module 100, including a front connector 10 and an IO housing 20. The front connector 10 and the IO housing 20 are pivotally connected by the aforementioned connection structure, and each has a built-in pluggable connection terminal. Under normal operation, the front connector 10 is plugged into the IO housing 20, and the built-in connection terminals of the two are interconnected. When repair or adjustment maintenance is required, the front connector 10 is rotated until it is supported on the protruding rib 23, at which point the operator can remove their hand from the front connector 10. After the operation is completed, the front connector 10 is rotated in the opposite direction until it is plugged into the IO housing 20. During the rotation of the front connector 10, the front connector 10 is not easily detached from the IO housing 20 due to the cooperation between the rotating shaft 21 and the snap-fit ​​groove 112. Secondly, the force during rotation is mainly borne by the abutment groove 111, while the snap-fit ​​groove 112 mainly plays the role of preventing detachment and is subjected to less force. Furthermore, since the operator is rotating the front connector 10, the arrangement of the rotating shaft 21 being located on the IO housing 20 and the snap-fit ​​groove 112 being located on the front connector 10 further reduces the force on the snap-fit ​​groove 112, thereby further reducing the probability of the front connector 10 detaching.

[0038] 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.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
