Rear housing threaded adapter

Abstract

This invention relates to a rear housing threaded adapter, comprising: a first component and a second component. The first component includes a first threaded section for threading a connector; the second component connects to the first component and includes a second threaded section for threading a rear housing, the second threaded section having a different radial dimension than the first threaded section. In this way, the rear housing threaded adapter allows for the combination of two products with different connection specifications from different product series without modification.

Claims

1. A rear-shell threaded adapter, comprising: A first component includes a first threaded section for threading a connector; and a second component connected to the first component includes a second threaded section for threading a rear housing, the radial dimension of the second threaded section being different from the radial dimension of the first threaded section.

2. The rear shell threaded adapter as claimed in claim 1, further comprising a waterproof component sandwiched between the first component and the second component.

3. The rear shell threaded adapter as claimed in claim 1, wherein the first member and the second member are interlocked together along an axial direction.

4. The rear shell threaded adapter as claimed in claim 3, wherein the first component and the second component are inseparably joined together.

5. The rear shell threaded adapter as claimed in claim 4, wherein the first component is recessed in a first annular groove perpendicular to the axial direction, the second component is recessed in a second annular groove perpendicular to the axial direction, and a retaining member is respectively embedded in the first annular groove and the second annular groove on both sides, so that the first component and the second component cannot be separated along the axial direction.

6. The rear shell threaded adapter as claimed in claim 5, wherein one end of the first component is provided with the first threaded section, and the other end is provided with the first annular groove and a beveled guide ring surface, the inner diameter of the beveled guide ring surface gradually decreasing towards the first annular groove; one end of the second component is provided with the second threaded section, and the other end is provided with the second annular groove and the locking member, the locking member being radially elastically deformable and positioned in the second annular groove; wherein, As the second component gradually penetrates deeper into the first component along the axial direction, the locking member is pressed against by the inclined guide ring surface and radially retracts into the second annular groove until the second annular groove corresponds to and connects with the first annular groove in the vertical direction. After the force is released, the locking member elastically resets and is embedded in the first annular groove.

7. The rear shell threaded adapter as claimed in claim 3, wherein the second member is inserted into the first member, the first threaded section is an internal threaded section, the second threaded section is an external threaded section, a first ring tooth is provided at one end of the second member for pressing against the adapter, and a second ring tooth is provided at the other end of the second member for pressing against the rear shell.

8. The rear shell threaded adapter as claimed in claim 3, wherein the second member is inserted into the first member, the second member comprising a plug portion, a necked portion and a connecting portion connected in sequence, the plug portion being inserted into the first member, the necked portion defining a clearance space with the first member, and the connecting portion having the second threaded section.

9. The rear shell threaded adapter as claimed in any one of claims 1 to 8, wherein the first member and the second member are rotatably connected together relatively independently.

10. The rear shell threaded adapter as claimed in claim 6, further comprising a waterproof component sandwiched between the first component and the second component; the second component is inserted into the first component, the first threaded section being an internal threaded section, the second threaded section being an external threaded section, a first ring tooth portion being provided at one end of the second component for pressing against the connector, and a second ring tooth portion being provided at the other end of the second component for pressing against the rear shell; the second component includes a plug-in portion, a necked portion, and a connecting portion sequentially connected, the plug-in portion being inserted into the first component, the necked portion defining a clearance space with the first component, and the connecting portion having the second threaded section; the first component includes a connected portion... The assembly comprises a first segment and a second segment. An anti-slip structure is provided on the outer ring wall of the first segment. The maximum wall thickness of the first segment is greater than that of the second segment. The first segment is provided with a first annular groove and a slanted guide ring surface. The plug-in portion includes a base and an annular protrusion. The base is connected to the necked portion. The annular protrusion protrudes from the base. The second annular groove is recessed into the annular protrusion. The first component and the second component are respectively made of aluminum alloy. A first coating is provided on the outer surface of the first component, and a second coating is provided on the outer surface of the second component. The plug-in portion is provided with a first annular tooth at one end opposite to the assembly portion, and the assembly portion is provided with a second annular tooth at one end opposite to the plug-in portion.
