Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to an antenna connector resistant to side thrust. Background Technology

[0002] like Figure 1 As shown, the existing side-push antenna connector has its front shell extending out of the inner cylinder and its rear end inside the rear shell. After being assembled into the antenna mounting base, it lacks sufficient holding force when subjected to lateral pushing and pulling forces. The resulting lever effect can easily damage and detach the front shell, and may also lead to antenna damage. Utility Model Content

[0003] In view of the above situation, it is necessary to propose an antenna connector that is resistant to side thrust.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a side-thrust resistant antenna connector, comprising:

[0005] An insulator with a through-channel inside;

[0006] The inner cylinder has a stepped hole consisting of small holes and large holes connected from front to back. The insulator is housed in the large hole. The through channel is connected to the small hole. A circular baffle is provided at the rear end of the inner cylinder.

[0007] The rear connecting cylinder includes a nested hole and a threaded hole that are connected from front to back. The nested hole and the threaded hole are separated by a spacer ring. The circular baffle is located in the nested hole and abuts against the spacer ring.

[0008] A waterproof ring is located inside the nested hole;

[0009] A spring washer is located inside the nested hole and clamps the waterproof ring with the circular baffle.

[0010] The rear shell is fitted over the rear connecting cylinder, and a retaining ring is provided at the front end of the rear shell to block the end of the spring washer away from the circular baffle.

[0011] The front shell is riveted and sleeved on the front end of the inner cylinder that extends out of the rear shell. The front shell is located outside the rear shell, and the inner cylinder has a protrusion that extends forward out of the front shell.

[0012] Furthermore, it also includes a conductive needle, which is nested with the through channel. The rear end of the conductive needle is provided with a convex cap, the outer diameter of which is larger than the inner diameter of the through channel.

[0013] Furthermore, the outer wall of the conductive needle is provided with an anti-retraction protrusion in the middle, and the anti-retraction protrusion has a forward-inclined guide slope.

[0014] Furthermore, the front end of the conductive needle is provided with a flexible insertion port.

[0015] Furthermore, the outer wall of the front end of the inner cylinder has a first stepped section, the bottom of which is flush with the end face of the front shell.

[0016] Furthermore, the front shell has a stepped mounting hole, and the portion of the inner cylinder protruding forward from the rear shell has a second stepped section that matches the stepped mounting hole.

[0017] Furthermore, the outer wall of the front shell is provided with a snap-fit ​​protrusion, which has a forward-inclined guide slope.

[0018] Furthermore, the outer wall of the front shell is provided with a pair of symmetrically arranged missing circular surfaces.

[0019] Furthermore, the diameter of the small hole is larger than the diameter of the through channel.

[0020] Furthermore, the insulator has a groove at its front end.

[0021] The beneficial effects of this utility model are as follows: the front shell wraps around the front end of the inner cylinder, the front end of the front shell does not protrude, and the rear end of the front shell is not located inside the rear shell. When subjected to lateral force, there is no lever fulcrum between the front shell and the inner cylinder; instead, they are in surface contact, thus preventing the formation of a lever effect. The force is distributed on the inner cylinder, avoiding the problem of the front shell detaching. The rear connecting cylinder is connected to the connector at the rear end through a threaded hole. A spring washer elastically abuts against the waterproof ring, sealing the inner cylinder and the rear connecting cylinder together. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of a side-thrust resistant antenna connector, in conjunction with the accompanying drawings and embodiments, is provided. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit its scope.

[0034] Please refer to Figures 2-5 A side-thrust resistant antenna connector, comprising:

[0035] Insulator 100, having a through channel 110 inside;

[0036] The inner cylinder 200 has a stepped hole formed by small holes 210 and large holes 220 connected from front to back. The insulator 100 is housed in the large hole 220. The through channel 110 is connected to the small hole 210. The rear end of the inner cylinder 200 is provided with a circular baffle 230.

[0037] The rear connecting cylinder 300 includes a nested hole 310 and a threaded hole 320 that are connected from front to back. The nested hole 310 and the threaded hole 320 are separated by a spacer ring 330. A circular baffle 230 is located inside the nested hole 310 and abuts against the spacer ring 330.

[0038] Waterproof ring 400, located inside nesting hole 310;

[0039] Spring washer 500 is located inside nesting hole 310 and clamps waterproof ring 400 with circular baffle 230;

[0040] The rear shell 600 is sleeved outside the rear connecting cylinder 300. The front end of the rear shell 600 is provided with a retaining ring 610, which blocks the end of the spring washer 500 away from the circular baffle 230.

[0041] The front shell 700 is riveted and sleeved on the front end of the inner cylinder 200 that extends out of the rear shell 600. The front shell 700 is located outside the rear shell 600, and the inner cylinder 200 has a protrusion that extends forward out of the front shell 700.

[0042] The front shell 700 is wrapped around the front end of the inner cylinder 200, but the front end of the front shell 700 does not protrude. The rear end of the front shell 700 is not located inside the rear shell 600. When subjected to lateral force, there is no lever fulcrum between the front shell 700 and the inner cylinder 200; instead, they are in surface contact, preventing the formation of a lever. The force is distributed across the inner cylinder 200, thus avoiding the problem of the front shell 700 falling off. The rear connecting cylinder 300 is connected to the connector at the rear end through a threaded hole 320. The spring washer 500 elastically abuts against the waterproof ring 400, sealing the space between the inner cylinder 200 and the rear connecting cylinder 300.

[0043] Please refer to Figure 5 It also includes a conductive needle 800, which is nested with the through channel 110. The rear end of the conductive needle 800 is provided with a convex cap 810, the outer diameter of which is larger than the inner diameter of the through channel 110. The conductive needle 800 is made of conductive material, generally copper or copper alloy, and its surface can be gold-plated as needed.

[0044] Please refer to Figure 5 The conductive pin 800 has an anti-retraction protrusion 820 in the middle of its outer wall. The anti-retraction protrusion 820 has a forward-sloping guide surface. The anti-retraction protrusion 820 is provided to prevent the conductive pin 800 from being forced back during the insertion process, which could lead to unstable connection or even failure.

[0045] Please refer to Figure 5 The conductive pin 800 has a flexible socket 830 at its front end. That is, the front end of the conductive pin 800 is a female connector, and the rear end is soldered with a cable or abuts against a spring pin.

[0046] Please refer to Figures 2-4 The inner cylinder 200 has a first stepped section 241 on its front outer wall, and the bottom of the first stepped section 241 is flush with the end face of the front shell 700. The first stepped section 241 allows the front end to be consistent with the outer diameter of existing products, facilitating docking.

[0047] Please refer to Figure 3 The front shell 700 has a stepped mounting hole 710 inside, and the portion of the inner cylinder 200 that protrudes forward from the rear shell 600 has a second stepped section 242 that matches the stepped mounting hole 710. Understandably, the inner diameter of the front end of the stepped mounting hole 710 is smaller than the inner diameter of the rear end to prevent the front shell 700 from moving backward.

[0048] Please refer to Figures 2-4The outer wall of the front housing 700 is provided with a snap-fit ​​protrusion 730, which has a forward-sloping guide bevel. This facilitates the engagement and connection between the housing and external devices.

[0049] Please refer to Figures 2-4 The outer wall of the front housing 700 has a pair of symmetrically arranged missing circular surfaces 720. This facilitates the mounting of other devices by clamping the missing circular surfaces 720.

[0050] Preferably, the diameter of the small hole 210 is larger than the diameter of the through channel 110. This ensures insulation between the conductive needle 800 and the inner cylinder 200.

[0051] Please refer to Figure 3 The insulator 100 has a groove 120 at its front end to facilitate sealing as needed. The insulator 100 is typically made of rubber.

[0052] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0053] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0054] In summary, this utility model provides a lateral thrust-resistant antenna connector where the front shell wraps around the front end of the inner cylinder, without protruding. The rear end of the front shell is not located within the rear shell. When subjected to lateral force, there is no lever fulcrum between the front shell and the inner cylinder; instead, they are in surface contact, preventing the formation of a lever effect. The force is distributed across the inner cylinder, avoiding the problem of the front shell detaching. The rear connecting cylinder is connected to the rear connector via a threaded hole. A spring washer elastically abuts against a waterproof ring, sealing the inner cylinder and the rear connecting cylinder.
