[0001] This utility model relates to a connector structure, and more particularly to a connector structure having a stress relief structure. Background Technology

[0002] Generally, connector structures with cable connections, such as general electrical connectors or connectors for dashcam video capture devices, often incorporate stress relief components between the connector housing and the cable to prevent damage from pulling. For connector structures installed outdoors, a certain degree of waterproofing is also necessary to prevent rainwater or dust from entering the connector structure.

[0003] Currently, a waterproof ring is placed at the connection between the stress-relieving component and the housing, and the stress-relieving component is fixed to the housing with screws, while simultaneously pressing and fixing the waterproof ring to meet waterproof requirements. However, this method requires the additional production of the waterproof ring and screw-locking components, increasing manufacturing costs. In addition, the stress-relieving component must also have a location for screw locking, which prevents the overall structure of the stress-relieving component and connector from meeting the miniaturization requirements, indicating room for improvement.

[0045] To better understand the technical content of this utility model, preferred embodiments are described below.

[0046] Figure 1 This is a schematic diagram of the connector structure according to the first embodiment of the present invention. Figure 2 for Figure 1 The diagram shown is an exploded view of the connector structure. Figure 3 for Figure 2 Please refer to the schematic diagram showing the internal components fitted onto the cable and the cable passing through the housing. Figure 1 , Figure 2 and Figure 3As shown. In this embodiment, the connector structure 1 includes a housing 10, a cable 20, and a stress relief structure 30. First, the connector structure 1 of this embodiment can be applied to connector structures 1 with cables 20, such as general electrical connectors or connectors for video acquisition devices with dashcams. It should be noted that the drawings disclosed only show the housing 10 portion of the connector structure 1; other electronic components may also be disposed inside the housing 10. The housing 10 of this embodiment includes an assembly portion 11 and a first engaging portion 12. The assembly portion 11 is disposed on the outer side wall of the housing 10 and protrudes outward from the outer side wall of the housing 10. Furthermore, the assembly portion 11 also includes a channel 111, which passes through the assembly portion 11 and communicates with the interior of the housing 10. Preferably, the assembly portion 11 is cylindrical, and the internal channel 111 may also be cylindrical. Preferably, the center of the assembly portion 11 may be coaxial with the center of the housing 10. The first engaging portion 12 is disposed on the assembly portion 11 and extends toward the channel 111. In other words, the first engaging portion 12 protrudes from the inner wall of the self-assembly portion 11 toward the center of the channel 111.

[0047] The stress relief structure 30 includes an inner component 31 and an outer component 32. The inner component 31 is fitted onto the cable 20. Preferably, in this embodiment, the inner component 31 is formed on the outer wall of the cable 20 by injection molding, such as insert molding. Figure 3 As shown. Preferably, in this embodiment, the inner component 31 is a cylinder for assembly to the assembly part 11. Furthermore, the inner component 31 includes a second engaging portion 311, which engages with the first engaging portion 12 of the housing 10. That is, the structure and position of the first engaging portion 12 and the second engaging portion 311 can be mutually matched. For example, in this embodiment, the first engaging portion 12 is a protrusion, one end of which is connected to the inner wall of the assembly part 11, and the other end extends towards the center of the channel 111.

[0048] Correspondingly, the second engaging portion 311 is disposed on the outer side wall of the inner member 31, and the second engaging portion 311 can be a groove or a sliding groove. Preferably, in this embodiment, the second engaging portion 311 is a sliding groove, and is disposed on the outer side wall of the inner member 31 along the circumferential direction of the inner member 31. Specifically, the second engaging portion 311 in this embodiment also includes an opening 3111, a first stop portion 3112, and a second stop portion 3113. The first stop portion 3112 and the second stop portion 3113 are disposed at intervals along the circumferential direction of the inner member 31 on the outer side wall of the inner member 31. Furthermore, the opening 3111 extends between the spaced-apart first stop portion 3112 and second stop portion 3113, together forming the structure of the sliding groove. Through the structure of the sliding groove, the inner member 31 can be screwed into the assembly portion 11 of the housing 10.

[0049] In other embodiments, the first engaging portion 12 can also be a groove or a slot, while the second engaging portion 311 can be a protrusion, achieving the same assembly effect. Preferably, the housing 10 of this embodiment has two first engaging portions 12, symmetrically arranged on the inner sidewall of the assembly portion 11. Correspondingly, the inner component 31 also has two second engaging portions 311 (refer to previous embodiments). Figure 4 (As shown). Specifically, in this embodiment, the first stop portion 3112 continuously surrounds the outer wall of the inner member 31 along its circumferential direction. The second stop portion 3113 discontinuously surrounds the outer wall of the inner member 31 to form multiple grooves, such as two grooves, serving as the second engaging portion 311 in this embodiment. In other embodiments, the first engaging portion 12 and the second engaging portion 311 may have other numbers or shapes, and this utility model is not limited thereto.

[0050] Figure 4 for Figure 2 Please refer to the schematic diagram showing the operation of assembling the internal components into the housing assembly section. Figure 3 and Figure 4 As shown. Specifically, a portion of the cable 20 can be passed through the channel 111 of the assembly section 11, such as... Figure 4 As shown. The inner component 31 is close to the assembly part 11, and one side of the first engaging part 12 (i.e., the protrusion) aligns with the opening 3111 of the second engaging part 311 (i.e., the groove), as shown. Figure 4 As shown. Next, the inner component 31 is inserted into the channel 111 of the assembly part 11 and rotated within the channel 111, so that the first engaging part 12 (i.e., the protrusion) completely enters the second engaging part 311 (the groove) from the opening 3111. That is, the first engaging part 12 (i.e., the protrusion) is fixed between the spaced-apart first stop part 3112 and second stop part 3113. At this time, the inner component 31 is assembled to the assembly part 11 of the housing 10, and the second engaging part 311 is connected to the first engaging part 12. The groove structure of the second engaging part 311 prevents the inner component 31 from detaching from the housing 10 due to the cable 20 being pulled. Specifically, when the two ends of the cable 20 are pulled, the first stop 3112 and the second stop 3113 can respectively limit the first engaging part 12 on both sides of the first engaging part 12, preventing the first engaging part 12 (i.e. the protrusion) from falling off between the first stop 3112 and the second stop 3113, and resisting the pulling force from both ends of the cable 20, thereby preventing the inner component 31 from detaching from the housing 10.

[0051] Preferably, the inner component 31 further includes a holding recess 312, which is disposed on the outer side wall of the inner component 31. Specifically, the inner component 31 in this embodiment is mainly a cylindrical structure, and the holding recess 312 is a structure that is slightly recessed from the outer side wall of the inner component 31. During the assembly of the inner component 31 to the housing 10, the holding recess 312 can be held by the assembly personnel or clamped and fixed by a jig to facilitate the assembly process.

[0052] Figure 5 for Figure 1 Please refer to the cross-sectional schematic diagram of the connector structure shown. Figure 1 , Figure 2 and Figure 5 As shown. After the inner component 31 is assembled into the housing 10, the outer component 32 covers the inner component 31 and part of the cable 20, thereby preventing external moisture or dust from entering the housing 10. In this embodiment, the outer component 32 is also formed by injection molding on the outer wall of the inner component 31 and the outer wall of part of the cable 20, referring to the part of the cable 20 close to the inner component 31. Preferably, in this embodiment, the outer component 32, in addition to covering the outer wall of the inner component 31 and part of the cable 20, extends to cover the outer wall of the assembly part 11. That is, the outer component 32 completely covers the outer wall of the inner component 31 and the assembly part 11 to achieve a better waterproof effect. Preferably, the assembly part 11 of the housing 10 also includes at least one groove 112, which is disposed on the outer wall of the assembly part 11. When the outer component 32 is formed by injection molding, it is simultaneously filled into the groove 112 on the outside of the assembly part 11, so that the outer component 32 can be placed in the groove 112, thereby increasing the strength of the connection between the outer component 32 and the housing 10, preventing the outer component 32 from falling off the housing 10 due to external force, or affecting the sealing between the outer component 32 and the housing 10.

[0053] Preferably, the connector structure 1 in this embodiment further includes a waterproof component 40, such as... Figure 2 and Figure 5 As shown. A waterproof component 40 is disposed within the channel 111 of the assembly part 11, and partially covers the cable 20 and the internal component 31, assembling it to one side of the assembly part 11. In other words, the waterproof component 40 covers the cable 20 and the internal component 31 located within the channel 111. In this embodiment, the waterproof component 40 is formed by filling the channel 111 of the assembly part 11 with waterproof adhesive and then drying it. Specifically, waterproof adhesive is injected into the channel 111 from the inside of the housing 10, and the waterproof adhesive covers the cable 20 and the internal component 31 located within the channel 111. After the waterproof adhesive dries and cures, the waterproof component 40 is formed, and the waterproof component 40 covers partially the cable 20 and the internal component 31, assembling it to one side of the assembly part 11. It should be noted that in this embodiment, the internal component 31 and the external component 32 are manufactured by injection molding, while the waterproof component 40 is formed by curing the waterproof adhesive. Figure 2The internal component 31, external component 32, and waterproof component 40 shown are all the structural shapes after molding.

[0054] Figure 6 This is a schematic diagram of the connector structure according to the second embodiment of the present invention. Figure 7 for Figure 6 Please refer to the exploded view of the connector structure shown. Figure 6 and Figure 7 As shown. The connector structure 1a of this embodiment also includes a housing 10, a cable 20a, a stress-relieving structure 30a, and a waterproof component 40. The housing 10 and the waterproof component 40 are the same as in the previous embodiment, so their component symbols can be used with reference to the foregoing description. The difference from the previous embodiment is that the cable 20a and the stress-relieving structure 30a are elbow-type. For example, the cable 20a also has an arc-shaped portion 21a, such as... Figure 7 As shown. Correspondingly, the inner component 31a of the stress relief structure 30a is also formed by injection molding on the arc-shaped portion 21a of the cable 20a, so that the inner component 31a also forms an arc-shaped structure sleeved on the outside of the cable 20a. Similarly, the inner component 31a includes a second engaging portion 311a that cooperates with the first engaging portion 12 of the housing 10. The structures of the first engaging portion 12 and the second engaging portion 311a are the same as in the previous embodiment, and can be a protrusion and a groove, respectively. The details of their assembly method can be referred to the description of the previous embodiment, and will not be repeated here. After the inner component 31a is assembled to the assembly portion 11 of the housing 10, the outer component 32a of the stress relief structure 30a is also formed on the outer side wall of the inner component 31a by injection molding, thereby forming an arc-shaped structure covering the inner component 31a and part of the cable 20a. Therefore, the stress relief structure 30a of this embodiment can also be applied to the elbow type structure.

[0055] In summary, the connector structure according to this utility model includes a housing, a cable, and a stress-relieving structure. The housing includes an assembly part and a first engaging part. The assembly part also includes a channel. The first engaging part is disposed in the assembly part and faces the channel. The stress-relieving structure includes an inner component and an outer component. The inner component is sleeved on the cable. Furthermore, the inner component includes a second engaging part, which cooperates with the first engaging part. After the cable passes through the channel of the assembly part of the housing, the second engaging part connects with the first engaging part, assembling the inner component into the housing. Then, the outer component covers the inner component and part of the cable, thereby preventing external moisture or dust from entering the housing. Compared with known connector structures and their stress-relieving components, the waterproof ring and related components for screw fastening can be eliminated, thereby reducing manufacturing costs. In addition, compared with known stress-relieving components, the stress-relieving structure of this utility model does not require additional space for screw fastening, allowing the stress-relieving structure of this utility model to be applied to miniaturized connector structures.
