Electronic device connection cord

Abstract

This utility model discloses an electronic device connector cable, comprising a connector body, a connector, and a dustproof assembly. The connector end has a plug-in portion for connecting electronic devices. The dustproof assembly includes a hollow dust cover, a spring, and a cover. One end of the dust cover is inserted into an annular groove at the connector end. An outer limiting slider slides against a limiting groove on the inner wall of the annular groove, ensuring its movement in a specific direction. A first mounting portion of the protruding outer part of the dust cover and a second mounting portion on the connector fix the spring, providing elasticity in its normal state, allowing the dust cover to protrude from the connector. The cover is detachably installed at the opening of the dust cover, covering the plug-in portion. This connector cable, through the cooperation of the dust cover and cover, effectively blocks dust and moisture from contacting the plug-in portion, avoiding poor contact caused by dust accumulation. During insertion and removal, the dust cover is compressed by external force and retracts along the limiting groove, without affecting use. After the external force disappears, it automatically resets under the action of the spring, continuously protecting the plug-in portion and preventing dust accumulation and damage.

Description

Technical Field

[0001] This utility model relates to the field of connection cable technology, specifically to an electronic device connection cable. Background Technology

[0002] In the digital age, electronic device connection cables serve as the link for data transmission and energy transfer between electronic devices, and their applications are becoming increasingly widespread. As the core component connecting the connection cable to the electronic device, the performance of the connector directly affects the stability and reliability of the entire connection system.

[0003] However, in actual use, the connector is constantly exposed to the external environment, facing the dual threats of dust contamination and physical damage. On the one hand, dust, particles, and other impurities easily adhere to the metal contacts of the connector, forming an insulating layer, which increases contact resistance, causing signal transmission attenuation, unstable power supply, and even equipment failure in severe cases. On the other hand, during daily use, handling, or storage, the connector is inevitably subjected to collisions and pressure, leading to pin deformation, breakage, or loosening of the interface, greatly shortening the service life of the connector. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides an electronic device connection cable that can effectively solve the technical problem of the lack of protection at the connector position of the current connection cable.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An electronic device connection cable includes a connection cable body and two connectors electrically connected at both ends of the connection cable body. The connectors are provided with plug-in portions for connecting electronic devices at their ends, and also include a dustproof component.

[0007] The dustproof assembly includes a hollow dustproof cover, several spring components, and a cover.

[0008] One end of the dust cover is movably inserted into the annular groove opened at the end of the connector. The dust cover is distributed around the plug-in part. The outer side of the dust cover is provided with a limiting slider that is embedded in the inner wall of the annular groove and slides. The inner wall of the annular groove is provided with a limiting groove that forms a sliding fit with the limiting slider.

[0009] The dust cover has several protrusions circumferentially arranged on its outer side. The protrusions have a first mounting part at one end near the connector. The connector has several second mounting parts at its end corresponding to the positions of the first mounting parts. The spring is disposed between the dust cover and the connector, and the two ends of the spring are fixed by the second mounting parts and the first mounting parts, respectively. The spring provides elastic force to make the dust cover slide away from the connector.

[0010] The cover is detachably installed on the opening at the end of the dust cover away from the connector and covers the insertion part.

[0011] Furthermore, the first mounting part includes a first groove and a first fixing rod protruding from the bottom of the first groove, and the second mounting part includes a second groove and a second fixing rod protruding from the bottom of the second groove. The two ends of the spring are respectively located in the first groove and the second groove, and are fixed by inserting the first fixing rod / second fixing rod at the corresponding positions into the interior of the spring.

[0012] Furthermore, the protrusions on the outer side of the dust cover are symmetrically distributed.

[0013] Furthermore, the outer side of the connector is provided with a third groove, and the cover is provided with a second snap-fit ​​part that matches the third groove. When the cover is removed from the dust cover, it can be fixed to the connector by inserting the second snap-fit ​​part into the third groove.

[0014] Furthermore, the cover is provided with a protruding first snap-fit ​​portion, and the cover is snapped and fixed to the opening of the dust cover through the first snap-fit ​​portion.

[0015] Furthermore, the connecting wire is provided with a high-temperature resistant layer and a wear-resistant layer from the inside to the outside.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The connecting cable provided by this utility model has a dust cover that protrudes from the connector under the elastic force of a spring in normal operation. Together with the cover, it can completely cover the plug part, effectively preventing dust, moisture and other impurities from directly contacting the plug part and avoiding poor contact due to dust accumulation. The dust cover slides with a limiting slider and a limiting groove, and can retract with external force when plugged in or out without affecting normal use. It automatically resets after use, always protecting the periphery of the plug part and preventing dust accumulation or damage. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figure 1-6 As shown, this utility model provides an electronic device connection cable, the main structure of which includes a connection cable body 1, a connector 2, and a dustproof component 3.

[0034] The connecting cable body 1 is provided with a high-temperature resistant layer 4 and a wear-resistant layer 5 from the inside to the outside. The high-temperature resistant layer 4 can be made of high-temperature resistant materials such as polyimide, which can ensure the normal operation of the connecting cable in high-temperature environments. The wear-resistant layer 5 can be made of wear-resistant materials such as polyurethane, which can effectively extend the service life of the connecting cable.

[0035] Two connectors 2 are fixedly connected to both ends of the connecting cable 1 and are electrically connected to the connecting cable 1. Each connector 2 has a plug-in portion 201 at its end, which is used to connect to electronic equipment to achieve functions such as data transmission or power supply. Simultaneously, an annular groove 202 is also provided at the end of the connector 2. The inner wall of the annular groove 202 has a limiting groove 203 that slides in conjunction with the limiting slider 311. The annular groove 202 and the limiting groove 203 are used to facilitate the installation and sliding of the dustproof component 3.

[0036] The structure of the dustproof component 3 mainly includes a hollow dustproof cover 31, several spring parts 32 and a cover 33.

[0037] The dust cover 31 has a hollow structure, with one end movably inserted into the annular groove 202. It is distributed around the periphery of the insertion part 201, providing dust protection. A limiting slider 311 on its outer side is embedded in a limiting groove 203 on the inner wall of the annular groove 202, allowing the dust cover 31 to slide stably along the annular groove 202. Several protrusions 312 are symmetrically distributed circumferentially on the outer side of the dust cover 31. A first mounting part 313 is provided at the end of each protrusion 312 near the connector 2. The first mounting part 313 includes a first groove 3131 and a first fixing rod 3132 protruding from the bottom of the first groove 3131. The first groove 3131 accommodates one end of the spring member 32, and the first fixing rod 3132 is inserted into the spring member 32 for fixation.

[0038] A spring member 32 is disposed between the dust cover 31 and the connector 2, with its two ends fixed by a second mounting portion 204 and a first mounting portion 313, respectively. The second mounting portion 204 at the end of the connector 2 corresponds to the first mounting portion 313. The second mounting portion 204 includes a second groove 2041 and a second fixing rod 2042 protruding from the bottom of the second groove 2041. During installation, the two ends of the spring member 32 are placed in the first groove 3131 and the second groove 2041, respectively, and the first fixing rod 3132 and the second fixing rod 2042 are inserted into the spring member 32 to achieve a stable installation of the spring member 32. The spring member 32 provides elastic force to allow the dust cover 31 to slide away from the connector 2. When the connecting wire is not in use, the dust cover 31 automatically pops out under the action of the spring member 32 to protect the insertion part 201.

[0039] The cover 33 is detachably installed on the opening of the dust cover 31 at the end away from the connector 2 and covers the insertion part 201. The cover 33 has a raised first snap-fit ​​part 332, which snaps and fixes to the opening of the dust cover 31 to ensure the stability of the cover 33 in the protected state. At the same time, the outer side of the connector 2 has a third groove 205, and the cover 33 has a second snap-fit ​​part 331 that matches the third groove 205. When the connecting line is in use and it is necessary to remove the cover 33 from the dust cover 31, the second snap-fit ​​part 331 can be inserted into the third groove 205 to fix it to the connector 2, preventing the cover 33 from being lost.

[0040] When using the electronic device connection cable, first remove the cover 33 from the dust cover 31. At this time, the dust cover 31 does not retract and will automatically extend outward to protect the plug portion 201 under the elastic force of the spring member 32. Then, insert the plug portion 201 of the connector 2 into the corresponding electronic device interface to complete the device connection. During connection, the dust cover 31 will automatically retract due to the space limitation of the electronic device, and due to the elastic force of the spring member 32, the dust cover 31 will always fit against the outside of the electronic device to achieve a dustproof effect. If it is necessary to temporarily place the cover 33, the second snap-fit ​​part 331 of the cover 33 can be inserted into the third groove 205 on the outside of the connector 2 for fixation. After use, first disconnect the connection cable from the electronic device. The dust cover 31 will automatically extend beyond the plug portion 201 under the elastic force of the spring member 32. Then, the cover 33 can be snapped and fixed to the dust cover 31 through the first snap-fit ​​part 332 to achieve dustproof protection for the plug portion 201.

[0041] Compared with traditional technologies, the connection cable provided by this technical solution has a dust cover 31 that protrudes from the connector 2 under the elastic force of the spring 32 in normal operation. Together with the cover 33, it can completely cover the plug part 201, effectively preventing dust, moisture and other impurities from directly contacting the plug part 201 and avoiding poor contact due to dust accumulation. The dust cover 31 slides with the limiting slide groove 203 through the limiting slider 311. It can retract with external force when plugged in or out without affecting normal use. It automatically resets after use, always protecting the periphery of the plug part 201 and preventing dust accumulation or damage.

[0042] 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. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
