Description

Technical Field

[0001] The utility model relates to the technical field of cable waterproof clamping joints, in particular to a double-threaded nylon cable waterproof joint. Background Art

[0002] Nylon cable connectors account for a high proportion of cable connectors, mainly because they can be mass-produced through injection molding, and are resistant to acids and alkalis, oils and corrosion, are light in weight, and are inexpensive. However, nylon cable connectors also have their own weaknesses, such as their strength is not as strong as that of metal cable connectors.

[0003] In addition, due to the limitation of the mold, the pitch is usually relatively large. When the accessory round nut and the joint body are assembled through threaded tightening, if the starting position of the round thread and the starting position of the joint are just in contact, the round nut is prone to twisting during threaded tightening. If it is forced in, the round nut and the joint body are prone to rubbing their threads, so that the round nut and the joint body are stuck and the product is damaged. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a double-threaded nylon cable waterproof connector.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a double-threaded round nut, a round nut slope is provided on the outer side of the upper end of the double-threaded round nut; an internal thread is provided on the inner side of the double-threaded round nut; a double-threaded joint body is provided on the inner lower end of the double-threaded round nut; joint body petals are provided on the upper end of the double-threaded joint body; a sealing bushing is embedded on the inner side of the double-threaded joint body; an embedded nut is embedded in the middle part of the outer side of the double-threaded joint body; a fixing nut is provided on the lower end of the outer side of the double-threaded joint body; the lower end of the embedded nut is slidably connected to a sealing ring, and the sealing ring is slidably connected to the upper end of the fixing nut.

[0006] Preferably, a groove is provided on the outer side of the petals of the joint body with the inner side center of the double-threaded joint body as the center; and the groove is arranged vertically.

[0007] Preferably, the sealing bushing is arranged in a conical shape, and is located inside the petals of the joint body and the double-threaded joint body.

[0008] Preferably, the sealing bushing is made of an EPAM rubber block, and the sealing bushing fits tightly with the joint body petals and the double-threaded joint body.

[0009] Preferably, the embedded nut and the fixing nut are threadedly connected to the double-threaded joint body, and the embedded nut and the fixing nut are slidably connected.

[0010] Preferably, the sealing ring is located outside the double-threaded joint body, and the sealing ring is slidably connected to the double-threaded joint body.

[0011] The utility model has the following beneficial effects:

[0012] Compared with the prior art, this double-thread nylon cable waterproof connector, through the provision of a double-thread connector body, a sealing ring and a double-thread round nut, adopts a double-thread central symmetric design on the round nut and the connector body. In this way, when the starting position of the round nut thread contacts the actual position of the connector body thread, the threads on both sides start to contact. During assembly, the qualified rate of production line assembly can be significantly improved, assembly is convenient, and product damage rate can be prevented. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Reference Figure 1-2 The utility model provides a double-threaded nylon cable waterproof connector: comprising a double-threaded round nut 1, a round nut slope 2 is provided on the outer side of the upper end of the double-threaded round nut 1; an inner thread 3 is provided on the inner side of the double-threaded round nut 1; a double-threaded joint body 4 is provided at the lower inner end of the double-threaded round nut 1; a joint body petal 5 is provided at the upper end of the double-threaded joint body 4; a sealing bushing 7 is embedded in the inner side of the double-threaded joint body 4; a sealing bushing 7 is embedded in the middle of the outer side of the double-threaded joint body 4 Embedded nut 8; a fixed nut 9 is provided at the lower end of the outer side of the double-threaded joint body 4; the lower end of the embedded nut 8 is slidably connected to the sealing ring 6, and the sealing ring 6 is slidably connected to the upper end of the fixed nut 9. When the double-threaded round nut 1 is assembled to the double-threaded joint body 4, if the thread starting position of the double-threaded round nut 1 and the thread starting position of the double-threaded joint body 4 just touch each other, the thread starting position and the thread starting position will contact at the same time, solving the problem of the traditional single-thread starting position contacting the round nut outward tilt.

[0018] As a further implementation scheme of the above technical solution: Figure 2As shown, a groove is opened on the outer side of the petals 5 of the joint body with the inner center of the double-threaded joint body 4 as the center of the circle; the groove is vertically arranged, and the double-threaded round nut 1 is installed on the double-threaded joint body 4. By rotating the threads of the double-threaded round nut 1, the petals 5 of the joint body are squeezed by the round nut inclined surface 2 on the double-threaded round nut 1 and deformed.

[0019] As a further implementation scheme of the above technical solution: Figure 1-2 As shown, the sealing bushing 7 is set in a conical shape, and the sealing bushing 7 is located inside the joint body petals 5 and the double-wire threaded joint body 4. The sealing bushing 7 is composed of EPAM rubber blocks, and the sealing bushing 7 is tightly fitted with the joint body petals 5 and the double-wire threaded joint body 4. When the joint body petals 5 squeeze the sealing bushing 7 inwardly, the sealing bushing 7 in the deformation zone of the sealing bushing 7 will shrink inwardly. At this time, the cable installed inside will be deformed, squeezed and tightened by the sealing bushing 7, thereby playing a role in waterproofing and fixing the cable.

[0020] As a further implementation scheme of the above technical solution: Figure 1-2 As shown, the embedded nut 8 and the fixing nut 9 are threadedly connected to the double-wire threaded joint body 4, and the embedded nut 8 and the fixing nut 9 are slidably connected. The lower end of the embedded nut 8 is slidably connected to the sealing ring 6, and the sealing ring 6 is slidably connected to the upper end of the fixing nut 9. The sealing ring 6 is located on the outside of the double-wire threaded joint body 4, and the sealing ring 6 is slidably connected to the double-wire threaded joint body 4. After installation, the lower end is installed on the customer's box. If the customer's box has a round hole, the embedded nut 8 is installed to the inside of the box before installation. After the double-wire threaded joint body 4 is inserted through, the fixing nut 9 is installed again to the outside of the double-wire threaded joint body 4. Before this, the sealing ring 6 can be inserted to the outside in advance and then the fixing nut 9 can be tightened. If the customer's box has a threaded hole, the double-wire threaded joint body 4 can be directly tightened to the box.
