Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a precise alignment guide device for coaxial connectors. Background Technology

[0002] Coaxial connectors are widely used components in electronic devices for transmitting radio frequency signals. They have important applications in fields such as communications, testing, and aerospace. Ensuring stable and reliable connection of connectors is crucial for the quality of signal transmission.

[0003] In the process of mating existing coaxial connectors, operators usually rely on manually aligning the plug and socket, or on the simple guiding structure of the housing itself. In situations such as blind mating, confined space, or high-density layout, this method can lead to alignment difficulties, resulting in misalignment of the plug and socket axes, i.e., misalignment.

[0004] Forcing an misaligned connector into the ground will not only result in excessive insertion and extraction force, but will also damage the fragile core pins or insulating medium inside the connector, affecting electrical performance and service life. At the same time, traditional connectors often lack an effective insertion buffer mechanism, and the rigid collision during mating will exacerbate this damage. In addition, many connectors rely solely on friction or simple threads for fixation after connection, which is not secure enough and can loosen or fall off under vibration or external pulling conditions.

[0005] Therefore, this utility model proposes a coaxial connector precision alignment guide device (case name) to address the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of inaccurate alignment, misalignment, lack of buffering of insertion force, and instability leading to detachment of coaxial connectors in the prior art, this utility model aims to provide a coaxial connector accurate alignment guide device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a coaxial connector precision alignment guide device, including: a connector plug, a connector socket for mating with the connector plug, and a guide mechanism and a connection mechanism disposed on the connector plug;

[0008] The guiding mechanism includes a slip ring that slides along the outer wall of the connector plug, a spring disposed between the slip ring and the connector plug, a plurality of connecting rods fixed to the slip ring, and a wedge block fixed to the right end of the plurality of connecting rods and having an inclined surface.

[0009] Furthermore, the connection mechanism includes a positioning pin fixed to the outer wall of the connector socket, a groove formed in the outer wall of the connector plug, a housing fixed to the outer wall of the connector plug, and a wedge with an inclined surface slidably connected inside the housing. The wedge is driven out by a spring and is used to limit the positioning pin after it slides into the groove.

[0010] Preferably, a sliding rod is fixedly connected to the rear side of the wedge, the outer wall of the sliding rod is fitted with the second spring, and the rear end of the sliding rod passes through the housing and is connected to the pull ring.

[0011] Preferably, the pull ring is used to pull the slide bar and the wedge head, causing the wedge head to retract into the housing to release the fixing of the positioning pin.

[0012] Preferably, a limit ring is fixedly connected to the outer wall of the connector socket.

[0013] Preferably, a washer is fixedly connected to the left side of the limiting ring. The washer is used to cooperate with the limiting ring to prevent over-insertion when the left end of the wedge contacts.

[0014] Preferably, when the wedge is subjected to force causing the slip ring to move to the left along the outer wall of the connector plug, the spring provides a restoring force to buffer the insertion force.

[0015] Preferably, after being centered by the inclined surface, the plurality of wedges encircle the connector socket and slide along the outer wall of the connector socket.

[0016] Preferably, as the locating pin slides into the groove, it contacts the inclined surface of the wedge and forces the wedge into the housing.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problems of inaccurate alignment, misalignment, and lack of buffering of insertion force in the prior art when coaxial connectors are connected by setting a guiding mechanism and using a wedge with an inclined surface to contact the connector socket during docking. In addition, a sliding slip ring and a spring are used.

[0019] 2. This utility model solves the problem of insufficient stability and loosening / falling off of the connector after docking by setting a connection mechanism, which utilizes the positioning pin on the connector socket to cooperate with the wedge driven by the spring in the connector plug groove. It automatically locks when inserted, ensuring a stable and reliable connection, and can be easily unlocked by a pull ring. Attached Figure Description

[0027] Example:

[0028] Please refer to Figures 1 to 4This utility model provides a precise alignment guide device for a coaxial connector, including a connector plug 1 and a connector socket 4 for mating with the connector plug 1. The connector plug 1 is provided with a guide mechanism 2 and a connecting mechanism 3. The guide mechanism 2 provides guidance, alignment, and buffering functions when the connector plug 1 mates with the connector socket 4. The connecting mechanism 3 provides a secure locking function after the connector plug 1 and connector socket 4 are mated. Specifically, the guide mechanism 2 includes a slip ring 201 that slides along the outer wall of the connector plug 1 and a spring 204 disposed between the slip ring 201 and the connector plug 1. The spring 204 provides buffering for the slip ring 201. Multiple connecting rods 202 are fixedly connected to the right side of the connector plug 1. The right end of the multiple connecting rods 202 is fixedly connected to the wedge block 203. The connecting mechanism 3 includes a positioning pin 301 fixed to the outer wall of the connector socket 4. A groove 302 is provided on one side of the outer wall of the connector plug 1. A housing 303 is fixed to the outer wall of the connector plug 1 on one side of the groove 302. A wedge head 304 is slidably connected inside the housing 303. A slide rod 305 is fixedly connected to the rear side of the wedge head 304. A spring 306 is sleeved on the outer wall of the slide rod 305. The rear end of the slide rod 305 passes through the housing 303 and is connected to the pull ring 307. A limit ring 205 is fixedly connected to the outer wall of the connector socket 4. A washer 206 is fixedly connected to the left side of the limit ring 205.

[0029] Please refer to Figure 2 and Figure 4 The slip ring 201 is slidably fitted onto the outer wall of the connector plug 1. A spring 204 is disposed between the slip ring 201 and the connector plug 1. The spring 204 is used to provide a restoring force when the slip ring 201 is subjected to force and moves to the left. The right side of the slip ring 201 is fixedly connected to a wedge 203 via multiple connecting rods 202. The wedge 203 has an inclined surface. Multiple wedges 203 are arranged in a ring around the circumference of the connector plug 1. The inclined surface of the wedge 203 is used to first contact the outer wall of the connector socket 4 during mating, thereby achieving automatic centering. A limit ring 205 is fixedly connected to the outer wall of the connector socket 4. A washer 206 is fixedly connected to the left side of the limit ring 205. The washer 206 is used to contact the left end of the wedge 203 to achieve limiting and avoid over-insertion.

[0030] Please refer to Figure 3 and Figure 4The connecting mechanism 3 includes a positioning pin 301 fixedly connected to one side of the outer wall of the connector socket 4. A groove 302 is correspondingly provided on one side of the outer wall of the connector plug 1. The housing 303 is fixed to the outer wall of the connector plug 1 and adjacent to the groove 302. A wedge head 304 is slidably connected inside the housing 303. The wedge head 304 has an inclined surface. A slide rod 305 is fixedly connected to the rear side of the wedge head 304. A second spring 306 is sleeved on the outer wall of the slide rod 305. The two ends of the second spring 306 abut against the inner wall of the housing 303 and the slide rod 305, respectively. The second spring 306 is used to drive the wedge head 304 to extend out of the housing 303. The rear end of the slide rod 305 passes through the housing 303 and is fixedly connected to a pull ring 307. The pull ring 307 is used to manually pull the slide rod 305 to retract the wedge head 304 into the housing 303.

[0031] As a preferred embodiment, please refer to Figure 3 and Figure 4 To provide a manual unlocking function, the structure of the connecting mechanism 3 is further defined. A slide rod 305 is fixedly connected to the rear side of the wedge 304 along the axial direction. A second spring 306 is sleeved on the outer wall of the slide rod 305. The rear end of the slide rod 305 extends out of the housing 303 and is fixedly connected to a pull ring 307. The pull ring 307 is used for the operator to pull, thereby causing the slide rod 305 and the wedge 304 to retract into the housing 303 against the elastic force of the second spring 306.

[0032] As another preferred embodiment, please refer to Figure 2 To provide precise insertion limit, a limit ring 205 is fixedly connected to the outer wall of the connector socket 4. A washer 206 is fixedly connected to the left side of the limit ring 205. The washer 206 surrounds the outer periphery of the connector socket 4. The end face of the washer 206 is used to contact the left end of the wedge 203, thereby working with the limit ring 205 to limit the insertion depth of the connector plug 1 and avoid excessive insertion that could damage the internal core pin.

[0033] Working principle: When connecting the connector plug 1 to the connector socket 4, the guide mechanism 2 guides the connector. First, the left side of the outer wall of the connector socket 4 contacts the wedge 203. The wedge 203 has an inclined surface. When the wedge 203 is subjected to force, it drives the connecting rod 202. The connecting rod 202 drives the slip ring 201 to move to the left along the outer wall of the connector plug 1. When the slip ring 201 moves to the left, it compresses the spring 204 located between the slip ring 201 and the connector plug 1. The spring 204 provides a restoring force to buffer the insertion force. Subsequently, the end of the connector socket 4 is centered by the inclined surfaces of multiple wedges 203. As it is gradually inserted, the multiple wedges 203 surround the connector socket 4 and slide along the outer wall of the connector socket 4 to avoid positioning errors. When the connector plug 1 is fully inserted into the connector socket 4, the left end of the wedge 203 contacts the washer 206. The washer 206 is fixedly connected to the left side of the limiting ring 205. The limiting ring 205 is fixedly connected to the outer wall of the connector socket 4. The limiting ring 205 and the washer 206 prevent over-insertion.

[0034] When the connector plug 1 is connected to the connector socket 4, the positioning pin 301, which is fixedly connected to one side of the outer wall of the connector socket 4, slides into the groove 302 opened on one side of the outer wall of the connector plug 1. During the sliding process, the positioning pin 301 contacts the inclined surface of the wedge head 304. The wedge head 304 has an inclined surface and is slidably connected in the housing 303 fixed to the outer wall of the connector plug 1. The positioning pin 301 squeezes the wedge head 304 into the housing 303. The movement of the wedge head 304 drives the slide rod 305 fixedly connected to the rear side. The slide rod 305 compresses the spring 306 sleeved on the outer wall. When the positioning pin 301 passes the wedge head... After step 304, the wedge 304 extends out of the housing 303 by the reset force of the spring 306, limiting the positioning pin 301 and fixing it in the groove 302. The connection between the connector plug 1 and the connector socket 4 is made more stable by the connecting mechanism 3. When it is necessary to release the fixing of the positioning pin 301, the pull ring 307 pulls the slide rod 305 and the wedge 304. The pull ring 307 is connected to the rear end of the slide rod 305, causing the wedge 304 to retract into the housing 303. At this time, the wedge 304 will not block the positioning pin 301, and the connector plug 1 and the connector socket 4 can be separated.
