Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to a connector with a guiding structure. Background Technology

[0002] In fields such as electronic equipment, industrial control, new energy vehicles, and aerospace, connectors are core components for achieving circuit conduction and signal transmission. The stability, accuracy, and convenience of their connections directly affect the operating efficiency and reliability of the entire system. With the increasing integration of equipment and the increasing complexity of application environments, higher requirements are placed on connectors in terms of guiding and positioning accuracy, anti-offset capability, ease of installation and maintenance, and heat dissipation performance.

[0003] In practical applications, the mounting base of connectors (such as equipment housings and circuit boards) may have assembly tolerances, or relative displacement may occur due to temperature changes or mechanical vibrations during use. Existing fixed-structure connectors cannot adapt to such minute displacements, easily leading to uneven stress on the connection points. Long-term use will accelerate component wear and reduce connection life. During the mating process, traditional connectors often experience misalignment between the plug and socket due to slight misalignment during installation (such as human error or positional deviation caused by equipment vibration). If the positioning deviation exceeds the allowable range, it may cause pin bending, poor contact, or even short circuits and signal interruptions. This positioning error is particularly significant in large-size connectors or multi-pin connectors. Traditional connector plugs and sockets are often fixed with bolts or integrated designs. When a connector is damaged and needs replacement, multiple fixing components must be disassembled, which is cumbersome and time-consuming. At the same time, different specifications of connectors usually cannot use the same mounting structure, increasing spare parts management costs and replacement difficulty. Therefore, a connector with a guiding structure needs to be designed. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a connector with a guiding structure.

[0005] The technical solution of the present invention is as follows: a connector with a guiding structure, comprising an insulating male shell, an insulating female shell, a first mounting sleeve, a plug connector, a mounting guide assembly, a positioning guide post, a locking nut, a floating guide assembly, a second mounting sleeve, a socket connector, and a positioning sleeve. The insulating male shell has a through groove at its bottom and mounting holes at its four corners. The insulating female shell also has mounting holes at its four corners. The first mounting sleeve is embedded in the center of the insulating female shell. The plug connector is precisely mounted on the first mounting sleeve via the mounting guide assembly. The insulating female shell has symmetrically mounted positioning guide posts, and the locking nut is threaded onto the upper part of the positioning guide post. The bottom of the insulating male shell has a floating guide assembly, and the second mounting sleeve is mounted on the floating guide assembly. The socket connector is precisely mounted on the second mounting sleeve via the mounting guide assembly. The floating guide assembly has symmetrically mounted positioning sleeves that cooperate with the positioning guide posts.

[0006] Preferably, the installation guide assembly includes a guide shaft, a plug rod, and a limiting ring. An L-shaped groove is spaced apart on the upper inner side of the first mounting sleeve. Guide shafts are spaced apart on the sidewalls of the plug connector. A limiting ring is provided on the lower inner side of the first mounting sleeve. The plug connector is fitted into the inner ring of the first mounting sleeve. The guide shaft on the plug connector mates with the L-shaped groove on the inner ring of the first mounting sleeve. Fixing holes are spaced apart between the plug connector and the sidewalls of the first mounting sleeve. The plug rod is inserted into the fixing holes on the sidewalls of the plug connector and the first mounting sleeve. An L-shaped groove is spaced apart on the lower outer side of the socket connector. Guide shafts are spaced apart on the upper inner side of the second mounting sleeve. The socket connector is fitted into the inner ring of the second mounting sleeve. The L-shaped groove on the socket connector mates with the guide shaft on the inner ring of the second mounting sleeve. Fixing holes are spaced apart between the sidewalls of the socket connector and the second mounting sleeve. The plug rod is inserted into the fixing holes on the sidewalls of the socket connector and the second mounting sleeve.

[0007] Preferably, the floating guide assembly includes a mounting base plate, a mounting ball bearing, a swing rod, a fixed plate, an elastic sleeve, and an elastic element. The mounting base plate has mounting ball bearings at the top near the four corners. The swing rod is rotatably connected to the mounting ball bearing via a ball bearing. The fixed plate has elastic sleeves embedded at the four corners. The swing rod passes through the elastic sleeves and is fitted with an elastic element. One end of the elastic element is connected to the fixed plate, and the other end of the elastic element is connected to the mounting ball bearing. The second mounting sleeve is embedded in the middle of the fixed plate, and the mounting base plate has a through hole in the middle.

[0008] Preferably, the end of the positioning guide post is tapered, and the inlet position of the positioning sleeve is inverted tapered.

[0009] Preferably, it also includes fixing blocks and limiting strips. Two fixing blocks are symmetrically arranged on the front and rear side walls inside the insulating male shell. A limiting strip is provided between the two fixing blocks on the left and between the two fixing blocks on the right. The two limiting strips play a role in isolating and limiting the fixing plate.

[0010] Preferably, the device also includes a retaining plate and a heat sink. Two retaining plates are embedded in the left and right side walls of the insulating male shell. The retaining plates are located on the upper and lower sides of the limiting strip. Two heat sinks are embedded in the left and right side walls of the insulating male shell. The heat sinks are connected to the retaining plates of similar height.

[0011] Preferably, the device also includes a locking assembly, which includes an elastic sheet, an inclined block, and a locking block. The elastic sheet is provided on both the front and rear side walls of the insulating male shell. An inclined block is provided on the upper part of the side wall where the two elastic sheets are close to each other. A locking block is provided on the upper part of the side wall where the two elastic sheets are close to each other. The locking block is located below the inclined block. The front and rear side walls of the insulating female shell are provided with a locking groove that mates with the locking block.

[0012] As a preferred option, the mounting base plate has ventilation holes on both sides.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. The positioning guide post features a tapered end design, while the positioning sleeve inlet adopts an inverted tapered design. When they contact each other, the inclined guide automatically corrects any deviation, ensuring precise insertion of the positioning guide post into the positioning sleeve. Simultaneously, the plug connector and the first mounting sleeve, and the socket connector and the second mounting sleeve, cooperate via L-shaped grooves and guide shafts to achieve pre-positioning during component installation. This dual-guide structure effectively avoids misalignment caused by human error or equipment vibration, reducing the risk of pin bending and poor contact.

[0015] 2. After the insulating female shell and the insulating male shell are mated, the locking assembly's locking block and slot precisely engage, and the bottom surface of the beveled block makes tight contact with the insulating female shell, forming a mechanical lock; the threaded engagement of the positioning guide post and the locking nut further secures the position of the insulating female shell. This multi-locking structure prevents the connector from loosening in a vibrating environment, ensuring the stability of circuit continuity and signal transmission during long-term use.

[0016] 3. The floating guide assembly, through the cooperation of the ball bearing seat and the swing rod, achieves rotational adjustment in the X and Y axes, and through the cooperation of the elastic sleeve and the elastic element, achieves displacement buffering in the Z axis. When the thrust is uneven during docking or there are tolerances in the installation foundation, the fixed plate can drive the socket connector to self-adaptively offset, and the elastic element absorbs stress through deformation, avoiding wear or damage to the plug and socket due to hard contact.

The connector 4 and the first mounting sleeve 3 have fixing holes 53 on their side walls. The lower part of the outer side wall of the socket connector 10 is spaced apart by an L-shaped groove 51. The upper side of the second mounting sleeve 9 is spaced apart by a guide shaft 52. The socket connector 10 is fitted into the inner ring of the second mounting sleeve 9. The L-shaped groove 51 on the socket connector 10 cooperates with the guide shaft 52 of the inner ring of the second mounting sleeve 9. The side walls of the socket connector 10 and the second mounting sleeve 9 are spaced apart by fixing holes 53. The insertion rod 54 is inserted into the fixing holes 53 on the side walls of the socket connector 10 and the second mounting sleeve 9.

[0028] like Figure 3 and Figure 5As shown, the floating guide assembly 8 includes a mounting base plate 81, a mounting ball bearing seat 82, a swing rod 83, a fixed plate 84, an elastic sleeve 85, and an elastic element 86. The mounting base plate 81 has mounting ball bearing seats 82 near its four corners. The swing rod 83 is rotatably connected to the mounting ball bearing seat 82 via a ball bearing. Elastic sleeves 85 are embedded at the four corners of the fixed plate 84. The swing rod 83 passes through the elastic sleeves 85, and an elastic element 86, which is a compression spring, is sleeved on the swing rod 83. One end of the elastic element 86 is connected to the fixed plate 84, and the other end is connected to the mounting ball bearing seat 82. A second mounting sleeve 9 is embedded in the middle of the fixed plate 84. A through hole is opened in the middle of the mounting base plate 81, and heat dissipation holes 17 are opened on both sides of the mounting base plate 81.

[0029] like Figure 3 As shown, it also includes a fixing block 12 and a limiting strip 13. Two fixing blocks 12 are symmetrically arranged on the front and rear side walls inside the insulating male shell 1. A limiting strip 13 is arranged between the two fixing blocks 12 on the left side and between the two fixing blocks 12 on the right side. The two limiting strips 13 play a role in isolating and limiting the fixing plate 84.

[0030] like Figure 7 As shown, it also includes a card plate 14 and a heat sink 15. Two card plates 14 are embedded in the left and right side walls of the insulating male shell 1. The card plates 14 are located on the upper and lower sides of the limiting strip 13. Two heat sinks 15 are embedded in the left and right side walls of the insulating male shell 1. The heat sinks 15 are connected to the card plates 14 at the same height.

[0031] like Figure 3 , Figure 4 and Figure 6 As shown, it also includes a locking assembly 16, which includes an elastic piece 161, an inclined block 162, and a locking block 163. Elastic pieces 161 are provided on the front and rear side walls of the insulating male shell 1. An inclined block 162 is provided on the upper part of the side wall where the two elastic pieces 161 are close to each other. A locking block 163 is provided on the upper part of the side wall where the two elastic pieces 161 are close to each other. The locking block 163 is located below the inclined block 162. The front and rear side walls of the insulating female shell 2 are provided with a slot 164 that mates with the locking block 163.

[0032] When needed, the operator presses the insulating female shell 2 against the insulating male shell 1. The tapered end of the positioning guide post 6 first contacts the inverted tapered slope of the positioning sleeve 11, thus guiding the positioning guide post 6 to be accurately inserted into the positioning sleeve 11. During the insertion of the positioning guide post 6, the insulating female shell 2 drives the plug connector 4 to connect and cooperate with the socket connector 10 of the insulating male shell 1. When the pushing force on the insulating female shell 2 is uneven during the connection process, the plug connector 4 tilts, causing the socket connector 10 to tilt. The fixing plate 84 and the swing rod 83 can move in corresponding positions in the X and Y axis directions. The elastic element 8 6. During the installation process, the socket connector 10 moves the fixing plate 84 in the Z-axis direction, and the insulating female shell 2 presses the inclined block 162, causing the elastic sheet 161 to shift to both sides. When the insulating female shell 2 and the insulating male shell 1 are in contact, the inclined block 162 causes the elastic sheet 161 to reset. The bottom of the inclined block 162 directly contacts the insulating female shell 2, and the locking block 163 is inserted into the locking groove 164 of the insulating female shell 2. When the pressing force disappears, the elastic element 86 drives the swing rod 83 and the fixing plate 84 to reset, thereby completing the corresponding guiding docking of the plug connector 4 and the socket connector 10. When the plug connector 4 and socket connector 10 are damaged and need to be replaced, or when different specifications of plug connector 4 and socket connector 10 need to be replaced, the operator pulls out the plug rod 54 and then rotates the plug connector 4 or socket connector 10 so that the guide shaft 52 of the plug connector 4 is aligned with the vertical groove of the L-shaped groove 51 of the first mounting sleeve 3, and then the plug connector 4 can be pulled upwards and removed. The vertical groove of the L-shaped groove 51 of the socket connector 10 is aligned with the guide shaft 52 of the second mounting sleeve 9, and then the socket connector 10 can be pulled upwards and removed. The guiding engagement of the L-shaped groove 51 and the guide shaft 52 can quickly complete the installation and engagement of the socket connector 10 and the plug connector 4, and the engagement of the fixing hole 53 and the plug rod 54 further completes the fixed positioning. When this device is working, the limiting strip 13 dissipates heat through the clamping plate 14 and the heat sink 15, and the heat dissipation holes 17 of the mounting base plate 81 can also dissipate heat.
