Description

Technical Field

[0001] The utility model belongs to the technical field of connection devices, and in particular relates to an adapter. Background Art

[0002] Car-mounted high-definition cameras generally use mini fakra connectors to reduce signal loss, but since camera models are different, the existing mini fakra connectors cannot be matched with all camera models, so an adapter is needed for adaptation.

[0003] In the related art, an existing adapter has one end connected to a camera and the other end connected to a connector. An adapter is coaxially arranged on the end connected to the camera, and the adapter is used to mate with the interface on the camera end. However, during the installation of the adapter, a retaining ring is used to achieve axial limitation. In a small space, the installation of the retaining ring is very inconvenient. At the same time, during the plugging and unplugging process, the retaining ring will be subjected to outward force due to the adapter. If the retaining ring is displaced axially, the adapter will become loose.

[0004] Therefore, how to prevent the adapter from loosening is a problem that those skilled in the art need to solve urgently. Utility Model Content

[0005] In order to solve the technical problems mentioned in the background technology, the utility model provides an adapter, which includes: a flange outer conductor body, which is axially opened with a first mounting through hole; an adapter, which is axially opened with a second mounting through hole; and a conductor assembly, one end of which is suitable for inserting into the second mounting through hole and interference fit with the adapter to form a crimping piece; wherein the crimping piece is suitable for inserting into the first mounting through hole, so that the adapter and the flange outer conductor body are interference fit.

[0006] In one embodiment, a first annular step is provided in the first mounting through hole; and the extending end of the adapter is interference fit with the first annular step.

[0007] In one embodiment, a second annular step is further provided in the first mounting through hole; the extending end of the adapter piece abuts against the second annular step.

[0008] In one embodiment, the conductor assembly includes: an insulator; wherein the insulator is suitable for being inserted into the second mounting through hole and having an interference fit with the extending end of the adapter.

[0009] In one embodiment, the outer side wall of the insulator is provided with a third annular step; the extending end of the adapter piece abuts against the third annular step.

[0010] In one embodiment, the diameter of the extending end is greater than the diameter of the third annular step, so that a protrusion is formed when the two abut against each other; wherein the protrusion abuts against the second annular step.

[0011] In one embodiment, the conductor assembly further comprises: a center conductor; wherein the center conductor is suitable for being inserted into the insulator and having an interference fit with the insulator.

[0012] In one embodiment, one end of the central conductor is a male head, and the other end is a female head; the male head protrudes from the insulator.

[0013] The beneficial effect of the utility model is that the adapter is installed by interference fit between the adapter and the first mounting through hole of the flange outer conductor body, and there is no need to set up additional clips, thus avoiding the possibility of failure of the clips affecting the adapter. At the same time, a conductor component is interference fit in the second mounting through hole of the adapter, which can prevent the second mounting through hole from being deformed when the adapter is subjected to external force, thereby affecting the firmness of the adapter.

[0027] like Figure 1 As shown, at least one embodiment provides an adapter, which includes: a flange outer conductor body 1, which is axially opened with a first mounting through hole 11; an adapter 2, which is axially opened with a second mounting through hole 21; and a conductor component 3, one end of which is suitable for inserting into the second mounting through hole 21 and interference fits with the adapter 2 to form a crimping part 4; wherein the crimping part 4 is suitable for inserting into the first mounting through hole 11, so that the adapter 2 and the flange outer conductor body 1 are interference fit.

[0028] In this embodiment, the adapter 2 is installed by interference fit with the first mounting through hole 11 of the flange outer conductor body 1, and there is no need to set up additional clips, thereby avoiding the possibility of failure of the clips affecting the adapter 2. At the same time, the conductor component 3 is interference fit in the second mounting through hole 21 of the adapter 2, which can prevent the second mounting through hole 21 from being deformed when the adapter 2 is subjected to external force, thereby affecting the firmness of the adapter 2.

[0029] like Figure 2 As shown, in some embodiments, a first annular step 111 is provided in the first mounting through hole 11 , and the presence of the first annular step 111 reduces the inner diameter of the first mounting through hole 11 , so that the insertion end 22 of the adapter 2 is interference fit with the first annular step 111 .

[0030] like Figures 1 to 3As shown, in some embodiments, a second annular step 112 is further provided in the first mounting through hole 11, and the inner diameter of the second annular step 112 is smaller than the inner diameter of the first annular step 111, which plays a positioning role; specifically, when the insertion end 22 of the adapter 2 moves in the first annular step 111, when it abuts against the second annular step 112, it indicates that it is in place.

[0031] like Figure 3 , Figure 4 As shown, in some embodiments, the conductor component 3 includes: an insulator 31; wherein the insulator 31 is suitable for being inserted into the second mounting through hole 21, and having an interference fit with the insertion end 22 of the adapter 2; the conductor component 3 also includes: a center conductor 32; wherein the center conductor 32 is suitable for being inserted into the insulator 31, and having an interference fit with the insulator 31; specifically, the interior of the insertion end 22 has an interference fit with the insulator 31, and the exterior has an interference fit with the first mounting through hole 11, that is, the radial force-bearing parts of each component are all in this section, so as to prevent other hollow parts from being deformed by force and affecting the firmness.

[0032] In some embodiments, one end of the center conductor 32 is a male head 321, and the other end is a female head 322; the male head 321 protrudes from the insulator 31; specifically, the male head 321 protrudes from the insulator 31, so that the insulator 31 will not be damaged during subsequent plug-in use.

[0033] In some embodiments, the outer wall of the insulator 31 is provided with a third annular step 311; the insertion end 22 of the adapter 2 abuts against the third annular step 311; the diameter of the insertion end 22 is larger than the diameter of the third annular step 311, so as to form a protrusion 221 when the two abut against each other; wherein the protrusion 221 abuts against the second annular step 112; specifically, the function of the third annular step 311 is to locate the installation position of the insulator 31, and the function of the protrusion 221 is to locate the installation position of the adapter 2.

[0034] To summarize, the adapter is installed by interference fitting the adapter 2 with the first mounting through hole 11 of the flange outer conductor body 1, without the need for additional clips, thereby avoiding the possibility of failure of the clips affecting the adapter 2. At the same time, the second mounting through hole 21 of the adapter 2 is interference fit with the conductor assembly 3, which can prevent the second mounting through hole 21 from being deformed when the adapter 2 is subjected to external force, thereby affecting the firmness of the adapter 2.
