Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a multi-core cable integrated connector. Background Technology

[0002] Multi-core cable integrated connectors are key components used in modern electronic equipment and industrial systems to realize signal and power transmission. They are used in communication equipment, industrial automation, transportation vehicles and medical instruments, etc., and carry reliable interconnection of multiple signals or power. In many application environments, especially connectors installed on construction machinery, rail vehicles or portable vibration equipment, they must maintain a stable connection state under continuous mechanical vibration or shock.

[0003] However, existing multi-core connectors rely on the friction between the pins and the socket to fix the plug and socket, or use a simple elastic snap-fit ​​structure. This connection method is acceptable in static environments, but it exposes serious deficiencies in dynamic vibration environments.

[0004] When a connector is subjected to long-term or intense vibration, simple friction or simple locking force will be overcome, resulting in a small relative displacement inside the connector. This displacement gradually accumulates, which can cause increased contact resistance and momentary signal interruption in mild cases, and in severe cases, cause the connector to become completely loose or even fall off, seriously threatening the operational stability and safety of the entire system.

[0005] Therefore, this utility model proposes a multi-core cable integrated connector to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of unstable connection and easy loosening and detachment in the existing multi-core cable integrated connector under vibration environment, resulting in low reliability, this utility model aims to provide a multi-core cable integrated connector with improved structure that can effectively solve the above problems.

[0007] This utility model provides a multi-core cable integrated connector, including: a protective shell, a connecting wire disposed at the front end of the protective shell, a connecting block with a connecting hole, and a locking mechanism.

[0008] The locking mechanism is used to securely lock the protective shell to the connecting block. The locking mechanism includes a rotating ring that is rotatably sleeved on the end of the protective shell, and an arc-shaped column that is fixedly connected to the inner wall of the rotating ring.

[0009] Furthermore, a corresponding sliding hole is provided on the connecting block. The protective shell, the connecting block, and the locking mechanism are locked together by rotating the rotating ring after the protective shell and the connecting block are connected, so that the arc-shaped column rotates and slides into the sliding hole.

[0010] Preferably, the connecting block is provided with a positioning block, and the end of the protective shell is provided with a positioning groove. The positioning block is adapted to be inserted into the positioning groove when the protective shell and the connecting block are docked, so as to ensure the guidance and accurate positioning of the docking.

[0011] Preferably, the multi-core cable integrated connector further includes a protective door, which is rotatably connected to the outside of the protective shell via a hinge. The protective door is used to shield the connecting wire in the non-connected state to protect the end of the connecting wire from external impact and contamination.

[0012] Preferably, the connector further includes a locking mechanism for locking the protective door. The locking mechanism includes a fixing groove one disposed on the protective shell and a fixing groove two disposed on the protective door, providing a basic structure for locking.

[0013] Furthermore, the locking mechanism also includes a sliding block, which is driven to be inserted into both the first fixing slot and the second fixing slot when the protective door is closed, thereby physically limiting the protective door.

[0014] Furthermore, the locking mechanism also includes a slider, which is fixedly connected to the locking block and slidably disposed on the protective shell. The operator can easily drive the locking block to move by pushing the slider to achieve locking or unlocking.

[0015] Preferably, the protective shell is provided with a hollow block, and the slider is slidably connected to the inner wall of the hollow block. The hollow block provides a guiding path and accommodating space for the slider to slide.

[0016] Preferably, the locking mechanism further includes a magnet, which is fixed to the inner wall of the second fixing groove and is used to attract the inserted card block to prevent the card block from accidentally coming out due to vibration, thus greatly enhancing the reliability of the protective door locking.

[0017] Preferably, the multi-core cable integrated connector further includes a rubber sleeve, which is fitted onto the tail of the protective shell and used to cover the root of the connecting wire, serving to buffer, seal, and protect the root of the cable.

[0018] Furthermore, the rubber sleeve is integrally formed with a limiting block that extends into the inner wall of the protective shell. The limiting block holds the protective shell in place through structural interference to prevent the protective shell from axially slipping off the rubber sleeve, thus ensuring the stability of the overall structure.

[0019] The beneficial effects of this utility model are as follows: 1. This utility model solves the problems of easy loosening and low connection reliability of connectors in the prior art under vibration environment by setting up a locking mechanism composed of a rotating ring, an arc-shaped column and a sliding hole. The rotating ring makes the arc-shaped column slide into the sliding hole for locking. This achieves a firm connection and strong vibration resistance.

[0020] 2. This utility model solves the problems in the prior art where the connector end is exposed and easily damaged by impact when the connector is transported or not connected, and the protective device is easily opened accidentally. By setting a protective door that is connected by a hinge and rotatably connected, and equipping the protective door with a locking mechanism consisting of a slider, a locking block and a magnet, the slider drives the locking block to insert into the fixing groove and is attracted by the magnet.

[0021] 3. This utility model solves the problems of inconvenient connector docking operation, easy insertion into the wrong position, and easy slippage of the protective shell from the cable in the prior art by setting positioning blocks and positioning grooves on the connecting block and the protective shell respectively, and setting a limiting block on the rubber sleeve for holding the protective shell. It achieves accurate positioning, convenient operation, error prevention, and a stable and durable overall structure. Attached Figure Description

[0031] Example: Please refer to Figures 1 to 4This utility model provides a multi-core cable integrated connector, which aims to solve the problems of insufficient connection reliability caused by connector loosening under vibration environment and easy damage to the connection end during transportation or in non-connection state in the prior art.

[0032] like Figure 1 and Figure 3 As shown, the multi-core cable integrated connector includes a protective shell 1 and a connecting block 201. A connecting wire 207 is provided at the front end of the protective shell 1. A connecting hole 206 for inserting the connecting wire 207 is provided on the connecting block 201. When the protective shell 1 and the connecting block 201 are mated, the connecting wire 207 is inserted into the connecting hole 206 to achieve electrical connection.

[0033] The multi-core cable integrated connector also includes a locking mechanism 2, which is used to lock the protective shell 1 to the connecting block 201. The locking mechanism 2 includes a rotating ring 204, which is rotatably sleeved on the end of the protective shell 1. The locking mechanism 2 also includes an arc-shaped column 203, which is fixedly connected to the inner wall of the rotating ring 204. The connecting block 201 has a sliding hole 202. When the protective shell 1 is connected to the connecting block 201, the operator rotates the rotating ring 204, which drives the arc-shaped column 203 to rotate synchronously. Finally, the arc-shaped column 203 slides into the sliding hole 202 of the connecting block 201, thus achieving a firm locking between the protective shell 1 and the connecting block 201.

[0034] like Figure 3 and Figure 4 As shown, a positioning block 205 is provided on the connecting block 201, and a positioning groove 209 is provided at the end of the protective shell 1. When the protective shell 1 and the connecting block 201 are mated, the positioning block 205 is adapted to be inserted into the positioning groove 209, which plays a guiding and anti-misinsertion role.

[0035] like Figure 1 and Figure 2 As shown, the multi-core cable integrated connector also includes a protective door 6, which is rotatably connected to the outside of the protective shell 1 via a hinge 3. The protective door 6 is used to shield and protect the connecting wire 207 at the front end of the protective shell 1 from external impact damage by rotating and closing when not connected.

[0036] like Figure 4 As shown, the multi-core cable integrated connector also includes a rubber sleeve 208, which is fitted onto the tail of the protective shell 1. The rubber sleeve 208 is used to cover the root of the connecting wire 207. A limiting block 11 is integrally formed on the rubber sleeve 208. The limiting block 11 extends into the inner wall of the protective shell 1 and is used to prevent the protective shell 1 from slipping off the rubber sleeve 208.

[0037] Please refer to Figure 1 , Figure 2 and Figure 4The locking mechanism includes a slider 10 and a locking block 5. The locking block 5 is fixedly connected to the slider 10, and the slider 10 is slidably mounted on the protective shell 1 to drive the locking block 5 to move. The protective shell 1 is provided with a hollow block 9, and the slider 10 is slidably connected to the inner wall of the hollow block 9. The hollow block 9 is used to limit the sliding path and range of the slider 10. The protective shell 1 is provided with a first fixing groove 4, and the protective door 6 is provided with a second fixing groove 7. When the protective door 6 is rotated to the closed state by the hinge 3, the operator can push the slider 10 to the right. The slider 10 drives the locking block 5 to move, and the locking block 5 is inserted into the first fixing groove 4 and the second fixing groove 7 in sequence, thereby realizing the physical locking of the protective door 6. The locking mechanism also includes a magnet 8, which is fixed to the inner wall of the second fixing groove 7. The magnet 8 is used to tightly attract the bottom of the locking block 5 after the locking block 5 is inserted into the second fixing groove 7. This magnetic attraction further enhances the locking reliability of the protective door 6 and prevents the slider 10 from unlocking and resetting itself due to accidental vibration of the protective door 6, ensuring the safety of the connecting line 207 during transportation.

[0038] As a preferred implementation method, to improve the accuracy of docking and prevent mis-insertion, please refer to... Figure 3 and Figure 4 The connecting block 201 is provided with a positioning block 205, and the end of the protective shell 1 is provided with a positioning groove 209. When the protective shell 1 and the connecting block 201 are mated, the positioning block 205 is adapted to be inserted into the positioning groove 209. Through the cooperation of the positioning block 205 and the positioning groove 209, the pre-interaction of the protective shell 1 and the connecting block 201 before engagement is ensured.

[0039] As another preferred embodiment, to protect the connecting ends during transport or in a non-connected state, please refer to... Figure 1 and Figure 2 The connector also includes a protective door 6, which is rotatably connected to the outside of the protective shell 1 via a hinge 3. The protective door 6 can be rotated to close to shield the connecting wire 207. The hinge 3 allows the protective door 6 to be easily opened or closed.

[0040] As a preferred embodiment, in order to protect the cable root and limit the housing, please refer to... Figure 4 The connector also includes a rubber sleeve 208, which is fitted onto the tail of the protective shell 1 and is used to cover the root of the connecting wire 207. The rubber sleeve 208 is preferably made of an elastic material and serves to cushion and seal.

[0041] Furthermore, in order to prevent the protective shell 1 from slipping off the rubber sleeve 208, a limiting block 11 is integrally formed on the rubber sleeve 208. The limiting block 11 extends into the inner wall of the protective shell 1 and is locked inside the protective shell 1 through structural interference to prevent the protective shell 1 from axially slipping off the rubber sleeve 208 under the action of external force.

[0042] Working principle: When connection is required, the operator aligns the protective shell 1 with the connecting block 201. At this time, the positioning block 205 on the connecting block 201 is adapted to be inserted into the positioning groove 209 at the end of the protective shell 1 for guidance. The operator continues to push the protective shell 1 so that the connecting wire 207 at the front end is inserted into the connecting hole 206 of the connecting block 201. After insertion, the operator rotates the rotating ring 204. Since the arc-shaped column 203 is fixedly connected to the inner wall of the rotating ring 204, rotating the rotating ring 204 will drive the arc-shaped column 203 to rotate synchronously and slide the arc-shaped column 203 into the sliding hole 202 opened on the connecting block 201. The locking mechanism 2 composed of the rotating ring 204, the arc-shaped column 203 and the sliding hole 202 provides a firm axial locking force, effectively preventing the connector from loosening due to vibration. In the transport or non-connected state, in order to protect the connecting line 207, the operator rotates the protective door 6 around the hinge 3 to close the protective door 6 and cover the front end of the protective shell 1. Then the operator pushes the slider 10 which is slidably connected to the inner wall of the hollow block 9. The slider 10 drives the fixedly connected locking block 5, so that the locking block 5 is inserted into the fixing groove 4 on the protective shell 1 and the fixing groove 7 on the protective door 6 in sequence. At this time, the magnet 8 fixed to the inner wall of the fixing groove 7 attracts the locking block 5. Through the physical limitation of the locking block 5 and the attraction and locking of the magnet 8, it is ensured that the protective door 6 will not be opened accidentally. In addition, the rubber sleeve 208 fitted at the tail of the protective shell 1 has an integrally formed limiting block 11 on the rubber sleeve 208. The limiting block 11 extends into the inner wall of the protective shell 1, and the structural interference is used to prevent the protective shell 1 from slipping off the rubber sleeve 208, thereby enhancing the stability of the overall structure.
