[0011] Furthermore, the guide portion arches towards the direction of the second fixed slot, and the contact surface between the guide portion and the movable conductor is inclined, with the top of the arch formed by the guide portion being arc-shaped.

[0012] Furthermore, the contact area between the contact portion and the fixed conductor is provided with a rounded corner.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of an SMA connector with a switching function, 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 the scope of the utility model.

[0040] Please refer to Figures 1-10 An SMA connector with a switching function, comprising:

[0041] The housing assembly 100 has a receiving cavity 111 inside. One end of the receiving cavity 111 has a through hole 112. One side of the receiving cavity 111 has a first fixing groove 113 communicating with the receiving cavity 111, and the other side has a second fixing groove 114 communicating with the receiving cavity 111.

[0042] The active conductor 200 is slidably fitted with the through hole 112;

[0043] The switch conductor 300 includes a main body 310 that is snapped into the first fixing slot 113. The main body 310 has an elastic part 320 that extends out of the first fixing slot 113 and inclinedly extends into the second fixing slot 114 at one end near the through hole 112. The switch conductor 300 extends out of the housing assembly 100 at one end away from the through hole 112 to form a first electrical connection part 330.

[0044] A fixed conductor 400 is disposed in the second fixed slot 114, and one end of the fixed conductor 400 away from the through hole 112 extends out of the housing assembly 100 to form a second electrical connection portion 410.

[0045] When the movable conductor 200 is not inserted into the receiving cavity 111, the elastic part 320 is in contact with the fixed conductor 400 and electrically connected; after the movable conductor 200 is inserted into the receiving cavity 111, the movable conductor 200 pushes the elastic part 320 away from the fixed conductor 400, the fixed conductor 400 is disconnected from the switch conductor 300, the movable conductor 200 is in contact with the fixed switch conductor 300 and electrically connected, and there is a disconnection gap between the movable conductor 200 and the fixed conductor 400.

[0046] The movable conductor 200 can be moved into the receiving cavity 111 through the through hole 112. The main conductor 310 of the switch conductor 300 is fixed in the first fixed slot 113, and the elastic part 320 extends out from the first fixed slot 113 and tilts towards the second fixed slot 114. When the fixed conductor 400 and the switch conductor 300 need to be connected, the movable conductor 200 is not inserted into the receiving cavity 111, and the inclined elastic part 320 contacts and connects with the fixed conductor 400 fixed in the second fixed slot 114. When the movable conductor 200 is inserted, it abuts against the elastic part 320, causing the elastic part 320 to move away from the fixed conductor 400. The movable conductor 200 is connected to the switch conductor 300 through the elastic part 320, and the fixed conductor 400 is disconnected from the switch conductor 300, and they do not contact each other. When the fixed conductor 400 and the switch conductor 300 need to be connected again, the movable conductor 200 is pulled out, and the elastic part 320 contacts and connects with the fixed conductor 400 again under the action of elastic restoring force. The entire structure is simple and convenient to implement, relying on the elastic deformation of the elastic part 320 for switching action. It has few parts, low cost, high reliability, and is easy to maintain.

[0047] Please refer to Figures 2-5The elastic portion 320 includes an elastic body 321, a guide portion 322, and a contact portion 323. The guide portion 322 is located at the end of the elastic body 321 away from the main guide body 310. The contact portion 323 extends from the elastic body 321 toward the side where the fixed conductor 400 is located. The movable conductor 200 abuts against the guide portion 322, causing the elastic body 321 to deform. Alternatively, as another embodiment of this utility model, the same part of the elastic portion 320 is responsible for contacting both the fixed conductor 400 and the movable conductor 200.

[0048] Please refer to Figures 2-5 The guide portion 322 arches towards the direction of the second fixed slot 114, and the contact surface between the guide portion 322 and the movable conductor 200 is inclined, with the top of the arch formed by the guide portion 322 being arc-shaped. That is, when the movable conductor 200 abuts against the arch, the elastic portion 320 is guided by the inclined surface to retract away from the fixed conductor 400. The arc-shaped top end makes the electrical contact between the guide portion 322 and the movable conductor 200 more stable.

[0049] Please refer to Figures 2-5 The contact portion 323 has a rounded corner at the contact point with the fixed conductor 400. In particular, the end face of the contact portion 323 facing the fixed conductor 400 is a slope, and the corner formed by the slope and the side face is rounded. A guide slope 1144 is also provided at the connection between the receiving cavity 111 and the second fixed slot 114. When the elastic portion 320 approaches the fixed conductor 400, the slope of the contact portion 323 and the guide slope 1144 cooperate to make the contact portion 323 electrically contact the fixed conductor 400.

[0050] Please refer to Figures 4-9 At least one side end face of the switch conductor 300 is provided with a first interference protrusion 311, which is interference-fitted with a first fixing groove 113. The end of the first fixing groove 113 away from the through hole 112 is provided with a first guide opening 1131. At least one side end face of the fixed conductor 400 is provided with a second interference protrusion 420, which is interference-fitted with a second fixing groove 114. The end of the second fixing groove 114 away from the through hole 112 is provided with a second guide opening 1141. The interference fit assembly is simple and convenient, facilitating maintenance. It is understood that both the first guide opening 1131 and the second guide opening 1132 gradually increase in height along the direction away from the through hole 112.

[0051] Please refer to Figures 4-9 The first fixing slot 113 extends vertically outward to have a first interface slot 1132, and the first electrical connection part 330 extends vertically outward from the first interface slot 1132; the second fixing slot 114 extends vertically outward to have a second interface slot 1142, and the second electrical connection part 410 extends vertically outward from the second interface slot 1142.

[0052] Please refer to Figures 2-4 The housing assembly 100 includes an inner housing 110 and an outer housing 120. The inner housing 110 is made of insulating material and is nested within the outer housing 120. A receiving cavity 111, a through hole 112, a first fixing slot 113, and a second fixing slot 114 are all formed within the inner housing 110. By using both the inner and outer housings 120, the inner housing 110 ensures insulation, and the outer housing 120 ensures sufficient strength. Preferably, the inner housing 110 is made of high-temperature resistant plastic, and the outer housing 120 is made of metal or an alloy.

[0053] Please refer to Figures 2-4 and Figure 10 The outer casing 120 has a mounting socket, and a third interference fit 121 is provided in the mounting socket. The inner casing 110 and the mounting socket are inserted and interference fit with the third interference fit 121. Preferably, the inner casing 110 and the outer casing 120 can also be reinforced by adhesive bonding.

[0054] Please refer to Figures 1-4 The outer casing 120 is provided with a threaded connection part 123 at one end near the through hole 112, and a clearance notch 122 is provided at the other end of the outer casing 120 away from the through hole 112 for the first electrical connection part 330 and the second electrical connection part 410 to protrude.

[0055] Please refer to Figures 6-9 The first fixing slot 113 has a first groove 1133 connected to the side facing away from the second fixing slot 114, and the height of the first groove 1133 is less than the height of the first fixing slot 113. The second fixing slot 114 has a second groove 1143 connected to the side facing away from the first fixing slot 113, and the height of the second groove 1143 is less than the height of the second fixing slot 114. The first groove 1133 and the second groove 1143 are designed to facilitate both installation and disassembly. The fixing conductor 400 or the switch conductor 300 can be easily removed using tools through the first groove 1133 and the second groove 1143.

[0056] 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.

[0057] 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.

[0058] In summary, this utility model provides an SMA connector with a switching function. The movable conductor is movably inserted into the receiving cavity through a through-hole. The main conductor of the switching conductor is fixed in a first fixed slot, and an elastic part extends from the first fixed slot and tilts towards a second fixed slot. When the fixed conductor and the switching conductor need to be connected, the movable conductor is not inserted into the receiving cavity, and the tilted elastic part contacts and connects with the fixed conductor fixed in the second fixed slot. When the movable conductor is inserted, it abuts against the elastic part, moving the elastic part away from the fixed conductor. The movable conductor connects with the switching conductor through the elastic part, and the fixed conductor and the switching conductor are disconnected, without contact. When the fixed conductor and the switching conductor need to be connected again, the movable conductor is pulled out, and the elastic part, under the action of elastic restoring force, contacts and connects with the fixed conductor again. The entire structure is simple and convenient to implement, relying on the elastic deformation of the elastic part for the switching function. It has few parts, low cost, high reliability, and is easy to maintain.
