Description

Technical Field

[0001] The present invention belongs to the technical field of connecting devices, and specifically relates to an electrical connector that is not easily broken. Background Art

[0002] An electrical connector is a precision electromechanical component used to connect, disconnect, or switch circuits. Its core function is to establish a reliable electrical signal and power transmission channel between two or more circuit nodes, while providing mechanical fixation and environmental protection. It mainly conducts current or signals through physical contact of metal contacts, such as pins. The fracture failure of an electrical connector is the result of the coupling of multiple factors such as mechanical stress, material defects, environmental erosion, and design deficiencies, which deeply affects the reliability and safety of the equipment.

[0003] An electrical connector disclosed in the prior art document with the publication number CN107768906B includes a housing formed of a plastic material and at least one terminal module disposed inside the housing. The housing has a base portion and a docking portion extending in the front-rear direction from the base portion. The docking portion has a docking surface in the up-down direction. The terminal module includes a conductive terminal having a contact portion and an insulating block. The contact portion of the conductive terminal is exposed on the docking surface. The electrical connector further includes two metal reinforcing members respectively assembled on the outer surface of the terminal module. The housing covers the terminal module and the metal reinforcing members. Due to the presence of the metal reinforcing members inside the electrical connector, the overall strength of the electrical connector is enhanced, so that the influence of shear stress on the electrical connector is reduced and it is not easily broken by direct force.

[0004] Although the above device adds metal reinforcing members inside the electrical connector to improve its anti-fracture ability, during the insertion and extraction process of the existing connector, it is very easy to generate axial stress of tension or extrusion on the pins, and vibration occurs during the use of the connector. Since the pins are usually fixedly connected to the insulating member and lack a stress compensation structure, they are very easy to be bent or broken by vibration, which is not conducive to the long-term use of the electrical connector. Summary of the Invention

[0005] To solve the problems proposed in the above background art that during the insertion and extraction process of the connector, it is very easy to generate axial stress of tension or extrusion on the pins, and vibration occurs during the use of the connector, which is likely to bend or break the pins by vibration, the present invention provides an electrical connector that is not easily broken.

[0006] To achieve the above object, the present invention provides the following technical solutions: An electric connector that is not easily broken, including a fixing plate, one side of the fixing plate is fixedly connected with a wiring head, the other side of the fixing plate is fixedly connected with a mounting seat, the side wall of the mounting seat is fixedly connected with a housing, the end of the housing is snap-connected with a rubber ring, a plastic plate is slidably abutted in the inner cavity of the housing, and pins are equidistantly inserted into the plastic plate. Further included are: a positioning and anti-disconnection mechanism connected to the housing; a compensation and anti-breakage mechanism connected to the positioning and anti-disconnection mechanism; Among them, the positioning and anti-disconnection mechanism extends and positions the plastic plate, and the compensation and anti-breakage mechanism assists the positioning and anti-disconnection mechanism to bend and lay the wire, reserving a stretching space.

[0007] Preferably, the positioning and anti-disconnection mechanism includes a stress relief sleeve bolted to the side wall of the plastic plate, a plurality of anti-slip rings are fixedly connected to the outer wall of the stress relief sleeve, at least a pair of guiding ridges are equidistantly fixedly connected to the inner surface of the housing, and the stress relief sleeve and the plastic plate are slidably connected to the guiding ridges through grooves.

[0008] Preferably, a first hub and a second hub are respectively slidably connected to both sides of the stress relief sleeve, a wire is fixedly penetrated between the first hub and the second hub, and the wire changes from a divergent state on both sides to a centered converging state after passing through the first hub and the second hub.

[0009] Preferably, a plurality of dome telescopic columns are equidistantly slidably connected to the upper and lower sides of the stress relief sleeve, the outer wall of the dome telescopic column is elastically connected to the inner cavity of the stress relief sleeve through a sliding plate, and the upper and lower sides of the stress relief sleeve are threadedly connected to the mounting seat through positioning bolts.

[0010] Preferably, the compensation and anti-breakage mechanism includes a pair of bases fixedly connected to the stress relief sleeve, a chute rotating rod is rotatably connected to the top of each base, a push plate is rotatably connected to the end of each chute rotating rod, and the side wall of the push plate is vertically slidably connected to the side wall of the second hub.

[0011] Preferably, a U-shaped plate is slidably connected to the middle chute of a pair of the chute rotating rods through a connecting shaft, and a lifting plate is fixedly connected to the pair of U-shaped plates.

[0012] Preferably, a threaded rod is threadedly connected to the middle of the lifting plate, and the threaded rod is rotatably connected to the stress relief sleeve through a rotating sleeve.

[0013] Preferably, the end of the wire passing through the second hub is fixedly connected to the pin, a spherical ball is fixedly connected to the root of the pin, and hook grooves are provided at both side edges of the plastic plate.

[0014] Preferably, a frame rod is inserted through the outer wall of the wire. The frame rod is divided into upper and lower parts, and the upper and lower parts of the frame rod are connected by a rectangular insertion block. The insertion pin is connected to the end of the wire.

[0015] Preferably, a rubber pad is sleeved on the outer wall of the insertion pin. The rubber pad is fixedly connected to the plastic plate. The rubber pad is divided into two parts and abuts against the outer wall of the spherical ball from both sides.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) Through the cooperation of structures such as the chute rotating rod and the frame rod, the present invention facilitates a certain degree of compensation effect for the insertion pin and the wire during the plugging and unplugging process of the connector. During the plugging and unplugging process of the connector, the insertion pin is subjected to axial stresses of extrusion and tension. Through the elastic extrusion of the spherical ball and the rubber pad, a certain degree of compensation effect can be achieved. At the same time, the wire connected to the end of the insertion pin is also slightly pulled and moved. At this time, the frame rod can rotate reversely to flatten the wire, and the reserved bent section of the wire can be used as the tensile displacement compensation, avoiding the situation of wire stretching and breaking after multiple pluggings and unplugging.

[0017] (2) Through the cooperation of structures such as the rubber pad, the spherical ball and the anti-slip ring, the present invention facilitates that the insertion pin is not easily broken during vibration. When the connector vibrates, the anti-slip ring arranged outside the stress elimination sleeve increases the friction between the stress elimination sleeve and the inner surface of the housing. Also, through the setting of the rubber pad, not only can adaptive compensation be carried out during installation, but also the vibration transmission to the insertion pin can be reduced, thereby effectively improving the assembly integration effect of the connector. Combined with the spherical ball arranged on the insertion pin, the anti-vibration ability of the root of the insertion pin can also be enhanced.

[0018] (3) Through the cooperation of structures such as the stress elimination sleeve and the dome telescopic column, the present invention facilitates the stable installation and positioning of the insertion pin. The stress elimination sleeve and the plastic plate as a whole are snapped and slid into the housing through the guiding protrusions. The guiding protrusions can ensure the lateral positioning of the stress elimination sleeve. During the movement, the dome telescopic column remains in a compressed state and pops out and snaps into the internal card slot of the mounting seat to perform longitudinal positioning on the stress elimination sleeve. Since a plurality of dome telescopic columns are equidistantly arranged, during the use of the connector, the shear stress received can be evenly dispersed to the mounting seat. The stress elimination sleeve can increase the relative installation area of the plastic plate and disperse the stress. Combined with the positioning bolts connecting the mounting seat and the stress elimination sleeve from both sides, the stability of the installation is further enhanced.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Such as Figures 1 to 12As shown in the figure, the present invention provides an electric connector that is not easily broken, including a fixing plate 1. One side of the fixing plate 1 is fixedly connected with a wiring head 2, and the other side of the fixing plate 1 is fixedly connected with a mounting base 3. The side wall of the mounting base 3 is fixedly connected with a housing 4. The end of the housing 4 is clamped with a rubber ring 5. A plastic plate 8 is slidably abutted against the inner cavity of the housing 4. Needles 9 are equidistantly inserted into the plastic plate 8. It further includes: a positioning and anti-disconnection mechanism 6, which is connected to the housing 4; a compensation and anti-breaking mechanism 7, which is connected to the positioning and anti-disconnection mechanism 6; Among them, the positioning and anti-disconnection mechanism 6 extends and positions the plastic plate 8, and the compensation and anti-breaking mechanism 7 assists the positioning and anti-disconnection mechanism 6 to bend and lay the wire, reserving a stretching space.

[0023] Adopting the above scheme: By connecting the wiring head 2 with the equipment cable, the fixing plate 1 can integrally install and position the connector at the designated position of the equipment. Through the housing 4, it is installed and guided with the butt joint, so that the needles 9 are inserted into the joint to complete the butt joint, and then it can be powered on and used. When the connector is in use, its anti-vibration ability and the effect of coping with multiple pluggings and unpluggings are good.

[0024] As Figure 1 and Figure 2 shown in the figure, the positioning and anti-disconnection mechanism 6 includes a stress relief sleeve 64 bolted to the side wall of the plastic plate 8. A plurality of anti-slip rings 65 are fixedly connected to the outer wall of the stress relief sleeve 64. At least a pair of guiding ridges 61 are equidistantly fixedly connected to the inner surface of the housing 4. The stress relief sleeve 64 and the plastic plate 8 are slidably connected to the guiding ridges 61 through grooves.

[0025] As Figure 4 and Figure 8 shown in the figure, a first hub 66 and a second hub 68 are respectively slidably connected to both sides of the stress relief sleeve 64. A wire 67 is fixedly penetrated between the first hub 66 and the second hub 68, and the wire 67 changes from a divergent state on both sides to a centered converging state after passing through the first hub 66 and the second hub 68; A plurality of dome telescopic columns 63 are equidistantly slidably connected to the upper and lower sides of the stress relief sleeve 64. The outer wall of the dome telescopic column 63 is elastically connected to the inner cavity of the stress relief sleeve 64 through a sliding plate. The upper and lower sides of the stress relief sleeve 64 are threadedly connected to the mounting base 3 through positioning bolts 62.

[0026] Adopting the above solution: The positioning bolt 62 is provided with a clamping groove corresponding to the position of the dome telescopic column 63 for clamping the dome telescopic column 63 at a specified position, and cooperating with the positioning bolt 62 to ensure the accurate positioning of the stress relief sleeve 64. A plurality of frame rods 79 are arranged in parallel, and each frame rod 79 can limit a row of electric wires 67. During installation, the stress relief sleeve 64 and the plastic plate 8 are integrally clamped and slid into the housing 4 through the guiding rib 61. The end of the stress relief sleeve 64 reaches the inside of the terminal 2. At this time, the dome telescopic column 63 reaches the position of the clamping groove inside the mounting seat 3 in a compressed state, and the dome telescopic column 63 is pushed up by the elastic force of the spring into the clamping groove for limiting. Since a plurality of dome telescopic columns 63 are arranged at equal intervals, during the insertion and extraction or use of the connector, the shear stress received can be evenly dispersed to the mounting seat 3.

[0027] As Figure 4 , Figure 7 and Figure 8 shown, the compensation and anti-breakage mechanism 7 includes a pair of bases 76 fixed inside the stress relief sleeve 64. The tops of the bases 76 are rotatably connected with sliding groove rotating rods 73. The ends of the sliding groove rotating rods 73 are rotatably connected with push plates 72. The side walls of the push plates 72 are vertically slidably connected with the side walls of the second hub 68; the middle sliding grooves of a pair of sliding groove rotating rods 73 are slidably connected with U-shaped plates 77 through connecting shafts. A pair of U-shaped plates 77 are jointly fixed with a lifting plate 78; a threaded rod 75 is threadedly connected to the middle of the lifting plate 78, and the threaded rod 75 is rotatably connected to the stress relief sleeve 64 through a rotating sleeve 74.

[0028] It should be noted that the way the side wall of the push plate 72 is vertically slidably connected with the side wall of the second hub 68 can be that the second hub 68 is provided with a vertical sliding groove, and the push plate 72 is vertically slidably connected on the vertical sliding groove on the side wall of the second hub 68, which will not be described in detail here.

[0029] As Figures 9 to 12 shown, the end of the electric wire 67 passing through the second hub 68 is fixedly connected with the pin 9. A spherical ball 711 is fixedly connected to the root of the pin 9. Hook grooves 71 are opened at both side edges of the plastic plate 8; the outer wall of the electric wire 67 is provided with a frame rod 79. The frame rod 79 is divided into upper and lower parts, and the upper and lower parts of the frame rod 79 are connected by a rectangular insertion block 710. The pin 9 is connected to the end of the electric wire 67; a rubber pad 712 is sleeved on the outer wall of the pin 9, and the rubber pad 712 is fixedly connected with the plastic plate 8. The rubber pad 712 is divided into two parts and abuts against the outer wall of the spherical ball 711 from both sides.

[0030] Adopting the above solution: When a bending setting is reserved for the wire 67, the lifting plate 78 is squeezed by rotating the threaded rod 75. Moving downward, the U-shaped plates 77 on both sides are synchronously driven downward by the lifting plate 78, so that the connecting shaft in the middle of the U-shaped plate 77 squeezes the chute rotating rod 73, and the pushing plate 72 is squeezed through the chute rotating rod 73, so that the pushing plate 72 pushes the second hub 68 to move away from the lifting plate 78. At this time, the wires 67 evenly distributed on the outside of the second hub 68 also move away from the lifting plate 78. Since the wires 67 are threaded through the middle of the frame rod 79, when the length of the wire 67 remains unchanged and the second hub 68 approaches the plastic plate 8, the wire 67 will be squeezed, and the frame rod 79 will be caused to rotate slightly, so that the wire 67 is bent. The frame rod 79 abuts against its bent part, preventing the wire 67 from being overly bent. At the same time, each row of wires 67 can be independently limited, achieving a combing effect and preventing the wires 67 from being messy. During the insertion and extraction of the connector, the pin 9 is subjected to axial stresses of extrusion and tension. Through the elastic extrusion of the spherical ball 711 and the rubber pad 712, a certain degree of compensation effect can be achieved. At the same time, the wire 67 connected to the end of the pin 9 is also slightly pulled and moved. At this time, the frame rod 79 can rotate reversely to flatten the wire 67, and the bent section reserved for the wire 67 can be used as a tensile displacement compensation, avoiding the situation of wire 67 tensile fracture after multiple insertions and extractions.

[0031] Through the working principle and usage process of the present invention: First, the staff manually screws the threaded rod 75, and the threaded rod 75 rotates on its own, so that the lifting plate 78 on its outer wall moves downward under the meshing drive of the threaded hole and the threaded rod 75. The U-shaped plates 77 on both sides are synchronously driven downward by the lifting plate 78, so that the connecting shaft in the middle of the U-shaped plate 77 squeezes the chute rotating rod 73, from Figure 7Observed from the angle, the chute rotating rod 73 rotates counterclockwise. Since the side wall of the push plate 72 is vertically slidably connected to the side wall of the second hub 68, the push plate 72 can be squeezed and pushed when the chute rotating rod 73 rotates, so that the push plate 72 pushes the second hub 68 to move in the direction away from the lifting plate 78. At this time, the wires 67 evenly distributed outside the second hub 68 also move in the direction away from the lifting plate 78. Since the wires 67 are inserted in the middle of the frame rod 79, when the length of the wires 67 remains unchanged and the second hub 68 is close to the plastic plate 8, the wires 67 will be squeezed and the frame rod 79 will be slightly rotated, so that the wires 67 will be moderately bent. When the wires 67 are bent, the frame rod 79 can just abut against the bent part to limit the position, avoiding excessive bending of the wires 67. At the same time, each row of wires 67 can be independently limited to achieve a combing effect and avoid the mess of the wires 67. The ball 711 provided at the root of the pin 9 can increase the anti-fracture ability of the pin 9. In combination with the rubber pads 712 provided on both sides, during the plugging and unplugging process of the connector, the pin 9 is subjected to axial stress of extrusion force and tension. The elastic extrusion of the ball 711 and the rubber pad 712 can achieve a certain degree of compensation effect. At the same time, the wire 67 connected to the end of the pin 9 is also pulled and moved slightly. At this time, the frame rod 79 can rotate in the opposite direction to flatten the wire 67, so that the reserved bending section of the wire 67 can be used as tensile displacement compensation to avoid the wire 67 from being stretched and broken after multiple plugging and unplugging. During the plugging and use of the connector, the operation of the peripheral equipment drives the connector to vibrate. The anti-slip ring 65 provided on the outside of the stress relief sleeve 64 increases the friction between the stress relief sleeve 64 and the inner surface of the housing 4. The rubber pad 712 reduces the vibration transmission to the pin 9, thereby effectively improving the assembly integration effect of the connector, and preventing the connection of the pin 9 from breaking during vibration. After the wire 67 is pre-bent and set, the stress relief sleeve 64 and the plastic plate 8 are slid into the housing 4 as a whole through the guide convex strip 61, and the end of the stress relief sleeve 64 reaches the inside of the terminal head 2. At this time, the dome telescopic column 63 remains in a compressed state and reaches the internal slot position of the mounting seat 3. The dome telescopic column 63 is lifted up and enters the slot limit position through the elastic force of the spring. Since multiple dome telescopic columns 63 are arranged at equal distances, the shear stress received can be evenly dispersed to the mounting seat 3 during the plugging or use of the connector, and the mounting seat 3 and the stress relief sleeve 64 are bolted together from both sides with the positioning bolts 62 to further enhance stability; After the stress relief sleeve 64 is installed, the docking connector is inserted into the pin 9 and threadedly connected to the housing 4. After installation and docking, it can be powered on and used. When this connector is used, it has good vibration resistance and can cope with multiple plug-in and pull-out effects.
