Description

Technical Field

[0001] This utility model relates to the field of wiring device technology, specifically to a multi-cavity combined waterproof wiring device. Background Technology

[0002] In waterproof wiring connections, common methods include stripping the wire and then protecting it with waterproof connector caps or tape, or using transverse piercing connections. These methods require a high level of expertise from the user, and improper operation can easily lead to waterproofing failure for general users. Currently available quick waterproof wiring devices typically only connect one set of wires. For example, a quick waterproof wiring device described in Chinese patent document "CN222072288U" uses insulating sealant and leverages the rebound force of an elastic block in conjunction with a rotating handle to push a clamping block to tighten the wires. This device is suitable for single-wire connections. When wiring, 2-3 waterproof wiring devices are usually required, which not only takes up space inside the junction box but also increases the cost of use. In addition, since the wire fixing of this type of waterproof wiring device is based on the rebound effect of the elastic block, this device is only suitable for connecting thinner and more flexible wires. For thicker wires with an outer diameter of 3mm or more, due to the high rigidity and large size of the wires, the clamping block is difficult to achieve an effective fixing effect under the self-rebound push of the elastic block. Therefore, this type of waterproof wiring device is not suitable for waterproofing connections of thicker wires such as those used in conventional lighting fixtures.

[0003] To address this, we propose a multi-cavity combined waterproof wiring device. Utility Model Content

[0004] This invention provides a multi-cavity combined waterproof wiring device to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0006] This utility model discloses a multi-cavity waterproof wiring device, including an insulating shell. The front end of the insulating shell is provided with several tubular socket chambers for accommodating the connectors of the connecting wires. It should be noted that the number of socket chambers is adapted to the number of cores of the multi-core wires, including but not limited to two-cavity and three-cavity chambers. Each socket chamber is pre-filled with insulating sealant, preferably non-curing insulating silicone grease. The front end of the insulating shell is provided with a wire clamping assembly for fixing the connecting wires. During the conductive connection process, after stripping the insulation from each group of wires, the wire ends are connected and inserted into a socket chamber respectively. Then, the wire clamping assembly is used to press and fix the insulation of all wires.

[0007] Since the insulating sealant is pre-filled into the socket cavity, when the wire end of the connector is inserted into the bottom of the socket cavity, the insulating sealant automatically overflows from the socket cavity under the pressure of the wire. During this process, the insulating sealant automatically fills the gap between the wire insulation in the socket cavity, forming a waterproof seal for the wire joint.

[0008] Furthermore, to enable the device to be used for waterproof sealing of thicker wire connectors, the wire clamping assembly includes a fixing platform and a wire clamping cover. The fixing platform and the wire clamping cover interlock to clamp and fix the wire connector. Specifically, one side of the fixing platform is integrally formed with the bottom of the front end of the insulating housing. One end of the wire clamping cover is connected to the end of the fixing platform by an integrally formed flexible thin wall. The end of the fixing platform away from the wire clamping cover has a slot, and the end of the wire clamping cover away from the fixing platform has an integrally formed pin for matching the slot. When the wire connector is inserted into the corresponding socket cavity, the wire clamping cover is flipped over, so that the pin on the wire clamping cover is inserted into the slot and fixed. This allows the wire clamping cover to lock the insulated wire with the fixing platform, preventing the wire connector from being easily pulled out of the socket cavity under external force.

[0009] Furthermore, in order to allow the clamping force between the wire clamping cover and the fixing platform to be flexibly adjusted according to the specifications of wires of different thicknesses, a guide platform is provided inside the slot. The top of the guide platform is designed with an inclined surface so that the pin can be smoothly inserted into the slot under the action of the guide platform when the wire clamping cover is rotated. At the same time, in order to achieve a self-locking and anti-retraction effect after the pin is inserted into the slot, the bottom of the guide platform forms a horizontal platform structure inside the slot. Meanwhile, on the outer side of the pin, there are horizontally designed locking steps integrally formed at equal intervals from top to bottom to cooperate with the guide platform.

[0010] Furthermore, in order to improve the stability and effectiveness of wire clamping when the wire clamping cover and the fixing platform are engaged, a clamping line is provided on the side of the wire clamping cover used to clamp the wire. In order to avoid damage to the wire insulation, an elastic rubber block can be added to the groove between the two clamping lines. On the one hand, this can prevent the clamping lines from damaging the wire surface, and on the other hand, it can increase the friction between the wire clamping assembly and the wire, thereby improving the stability of clamping and fixing.

[0011] The advantages of this utility model over the prior art are as follows:

[0012] This utility model adopts an integrated design with multiple cavities, which can be used independently or in conjunction with metal conduits. It can make waterproof connections of multiple sets of wire joints at one time. Its structure is simple, easy to use, has good waterproof and insulation performance, and low overall cost. It can be widely used for wiring of indoor, outdoor and underground wires. Moreover, the device can effectively fix thicker wires by using the wire clamping cover, clamping line, and the cooperation of the plug, fixing platform and slot, and has a good anti-loosening effect, which can effectively improve the safety and effectiveness of waterproof wiring.

[0025] Example:

[0026] To address the limitations of existing rapid waterproof wiring devices, such as those described in "CN222072288U", which cannot simultaneously waterproof the terminals of multiple sets of wires and are unsuitable for waterproofing thicker wires, we propose a multi-cavity combined waterproof wiring device. The specific solution is as follows:

[0027] This utility model discloses a multi-cavity waterproof wiring device, specifically including an insulating shell 1. The front end of the insulating shell 1 is provided with several tubular socket chambers 12 for accommodating the connectors of the connecting wires. It should be noted that the number of socket chambers 12 is adapted to the number of cores of the multi-core wire, including but not limited to two-cavity and three-cavity chambers. Each socket chamber 12 is pre-filled with insulating sealant 2, which is preferably non-curing insulating silicone grease. The front end of the insulating shell 1 is provided with a wire clamping assembly for fixing the connecting wires. During the conductive connection process, after the wire ends of each group of wires with the insulation stripped are connected, they are inserted into a socket chamber 12 respectively, and then the insulation of all wires is pressed and fixed by the wire clamping assembly.

[0028] Since the insulating sealant 2 is pre-filled into the socket cavity 12, when the wire end of the connecting wire is inserted into the bottom of the socket cavity 12, the insulating sealant 2 automatically overflows from the socket cavity 12 under the pressure of the wire. During this process, the insulating sealant 2 automatically fills the gap between the wire insulation in the socket cavity 12, forming a waterproof seal for the wire joint.

[0029] To enable the device to be used for waterproof sealing of thicker wire connectors, its wire clamping assembly includes a fixing platform 5 and a wire clamping cover 6. The fixing platform 5 and the wire clamping cover 6 are interlocked to clamp and fix the wire connector. Specifically, one side of the fixing platform 5 is integrally formed with the bottom of the front end of the insulating housing 1. One end of the wire clamping cover 6 is connected to the end of the fixing platform 5 by an integrally formed flexible thin wall 7. The end of the fixing platform 5 away from the wire clamping cover 6 has a slot 8. The end of the wire clamping cover 6 away from the fixing platform 5 has an integrally formed pin 11 for matching the slot 8. When the wire connector is inserted into the corresponding socket chamber 12, the wire clamping cover 6 is flipped over, so that the pin 11 on the wire clamping cover 6 is inserted into the slot 8 and fixed. This allows the wire clamping cover 6 to work with the fixing platform 5 to tighten the wire with insulation, preventing the wire connector from being easily pulled out of the socket chamber 12 under external force.

[0030] To allow the clamping force between the wire clamping cover 6 and the fixing platform 5 to be flexibly adjusted according to the specifications of wires of different thicknesses, a guide platform 9 is provided inside the slot 8. The top of the guide platform 9 is designed with an inclined surface so that the pin 11 can be smoothly inserted into the slot 8 under the action of the guide platform 9 when the wire clamping cover 6 is rotated. At the same time, in order to enable the pin 11 to achieve a self-locking and anti-retraction effect after being inserted into the slot 8, the bottom of the guide platform 9 forms a horizontal platform structure inside the slot 8. Meanwhile, on the outer side of the pin 11, there are horizontally designed locking steps that are integrally formed at equal intervals from top to bottom to cooperate with the guide platform 9.

[0031] To improve the stability and effectiveness of wire clamping when the wire clamping cover 6 and the fixing platform 5 are engaged, a clamping line 10 is provided on the side of the wire clamping cover 6 used to clamp the wire. In order to avoid damage to the wire insulation, an elastic rubber block can be added to the groove between the two clamping lines 10. On the one hand, this can prevent the clamping line 10 from damaging the wire surface, and on the other hand, it can increase the friction between the wire clamping assembly and the wire, thereby improving the stability of clamping and fixing.

[0032] Unlike the above embodiments, depending on the device model and size, and the requirements of the fixed wire specifications, the fixing platform 5 and the wire pressing cover 6 can also be fixed with screws, eliminating the need for the engagement of the pin 11 and the slot 8 in the above embodiments.

[0033] When using this device, taking the multi-cavity combined waterproof wiring device of this utility model as an example, with two multi-core wires in operation, such as... Figures 3-4 Taking the connection between the first main line 3 and the second main line 4 as an example:

[0034] The workers stripped the head insulation of the inner cores of the first main line 3 and the second main line 4, and connected the exposed cores of the two wires respectively. They then inserted the connected wire connectors into the corresponding socket chambers 12. Finally, they fastened and fixed the wire clamping cover 6 to the fixing platform 5 to press and fix all the wires to prevent the waterproof wiring device from falling off the wires.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
