Description

Technical Field

[0001] This invention relates to the field of electrical connectors, and more specifically to an anti-loosening electrical connector for mechanical and electrical equipment. Background Technology

[0002] Electrical connectors are the link between wire harnesses, used to quickly connect two segments of cable. Common electrical connectors include male and female connectors. Male and female connectors are a collective term for the two ends of a set of connectors or extension cables, also known as positive and negative connectors. Male and female connectors are located at the corresponding ends of the cables to be connected, and the connection between the two segments of the cable is achieved by inserting or removing the male and female connectors. Male connectors use protruding pins or needle-like conductor structures, while female connectors use recessed sockets or hole-like conductor structures. The shapes and quantities of the two must match to achieve physical connection and signal transmission. Standard requirements stipulate that the mating force of connectors must not exceed 75N, thus the locking structures equipped between the male and female connectors have shown diversified development trends. Currently, the locking structures of common connectors on the market are roughly divided into five categories: hook-type, gear-type, bolt-assisted type, steel clip locking type, and threaded locking type.

[0003] The steel clip locking connector includes a hanging point block and a steel clip. The hanging point block is fixed to the outer wall of the male connector's sheath. The end face of the hanging point block away from the cable on the male connector is beveled, while the end face of the hanging point block near the cable on the male connector is a plane perpendicular to the cable. The inner wall of the female connector's sheath has a groove that slides along the length of the cable to engage with the hanging point block. The outer wall of the female connector's sheath has an annular groove that surrounds the cable circumference, and the annular groove and the groove are connected. The steel clip is a U-shaped elastic rod; the steel clip includes two symmetrical locking rods and a connecting rod; the two locking rods are distributed on both sides of the connecting rod and are perpendicular to the connecting rod. The locking rods and the connecting rod are fixedly connected, making the steel clip U-shaped. The end of the locking rod away from the connecting rod has a protrusion that protrudes towards the symmetrical plane of the two locking rods. When connecting cables, first align the opening of the steel clip with the cable, and insert the clip rod perpendicular to the cable into the annular groove. When the protrusion slides to the groove, it engages. As the male connector is inserted into the female connector, the locking block moves down along the groove, its inclined surface abutting against the protrusion and pushing it out of the groove. When the locking block passes the protrusion, it resets and locks itself on the plane perpendicular to the cable, thus locking the male and female connectors. Due to the superior deformation resistance of the elastic steel clip, steel clip locking connectors are widely used in relatively complex environments. However, because the installation and removal of the steel clip require insertion and removal within the annular groove perpendicular to the cable, it has certain limitations when connecting male and female connectors in relatively confined spaces. Summary of the Invention

[0004] This invention provides an anti-loosening electrical connector for mechanical and electrical equipment to solve the above-mentioned problems.

[0005] The present invention provides an anti-loosening electromechanical connector, which adopts the following technical solution: an anti-loosening electromechanical connector, comprising a male head, a female head, and a locking component.

[0006] The male connector includes a housing; the housing is fixed to one end of a section of the cable.

[0007] The female connector includes a housing; the housing is fixed to the end of another cable; the end of the housing near the male connector has a slot; when the male and female connectors are connected, the housing is inserted into the slot.

[0008] The locking assembly includes a groove, a hanging block, and a steel clip; two grooves are symmetrically provided and are formed on the side wall of the slot; two hanging blocks are symmetrically provided and are fixed to the outer wall of the housing; the end face of the hanging block near the female head is a mating surface; the mating surface is an inclined surface that is inclined relative to the insertion direction of the male and female heads, and the end face of the hanging block away from the female head is a locking surface; the locking surface is a plane perpendicular to the insertion direction; when the housing is inserted into the slot, the hanging block is inserted into the groove.

[0009] The steel clip includes a rotating rod and an auxiliary structure; two rotating rods are symmetrically arranged; the rotating rod is an elastic rod perpendicular to the insertion direction, and the two rotating rods are parallel; the rotating rod is located between the sleeve and the insert; both ends of the rotating rod are mounted on the sleeve through the mounting structure around an axis perpendicular to the insertion direction; the middle part of the rotating rod is bent towards the center of the sleeve to form a locking protrusion; the locking protrusion is located on the side of the groove closer to the male end.

[0010] When the male and female connectors are inserted, the auxiliary structure restricts the rotation of the rotating rod, causing the locking protrusion to abut against the locking surface and lock the hanging block in the groove. Before the male and female connectors are separated, the auxiliary structure applies force along the insertion direction to drive the rotating rod to rotate, causing the locking protrusion to rotate away from the locking surface and unlock the hanging block. The direction of the locking protrusion of the rotating rod and the unlocking action of the hanging block are parallel to the insertion direction of the male and female connectors, which is beneficial for operation in small and compact spaces and improves the connection efficiency of the male and female connectors.

[0011] Furthermore, two auxiliary structures are provided, symmetrically located at both ends of the rotating rod; each auxiliary structure includes an auxiliary rod and an operating unit; two auxiliary rods are provided, symmetrically located between the two rotating rods; each auxiliary rod corresponds to one rotating rod; the auxiliary rod is an elastic rod, including an inclined section and a parallel section; the inclined section is located on the side of the parallel section closer to the male end; the inclined section is inclined relative to the insertion direction, and the inclined sections of the two auxiliary rods of the same auxiliary structure form a V-shape with the opening facing the male end; the parallel section is parallel to the insertion direction; the inclined section is fixedly connected to the corresponding rotating rod; the parallel sections of the two auxiliary rods of one auxiliary structure are fixedly connected by a U-shaped rod.

[0012] Before the male and female heads are separated, the operating unit applies force along the insertion direction to push the parallel section and drive the inclined section to rotate. The inclined sections of the two auxiliary rods of the same auxiliary structure are V-shaped with the small end facing the male head, so as to drive the rotating rod to drive the locking protrusion to rotate away from the locking surface.

[0013] Furthermore, the operating unit includes an operating plate; the operating plate extends along the insertion direction of the male and female connectors; the operating plate is located on one side of the insert housing; the end of the operating plate away from the female connector is slidably mounted on the insert housing along the insertion direction of the male and female connectors via a sliding structure; a U-shaped plate with an opening facing the insert housing is fixed to the end of the operating plate near the female connector. During the process of inserting one end of the insert housing into the slot, the mating surface of the hanging block abuts against the locking protrusion, causing the rotating rod to elastically deform and push the locking protrusion open. When the hanging block passes the locking protrusion and enters the groove, the locking protrusion resets and abuts against the locking surface of the hanging block, locking the hanging block in the groove. During this process, the parallel sections of the two auxiliary rods of the same auxiliary structure are engaged into the opening of the U-shaped plate. Before separating the male and female connectors, push the operating plate away from the female connector by hand along the insertion direction of the male and female connectors. When the U-shaped plate moves to the junction of the inclined and parallel sections, the U-shaped plate applies a thrust along the insertion direction to the inclined section, causing the inclined section to rotate. This makes the inclined sections of the two auxiliary rods of the same auxiliary structure form a V-shape with the smaller end facing the male connector, driving the rotating rod to rotate the locking protrusion away from the locking surface, thereby unlocking the hanging block. Then, pull the male and female connectors by hand to pull the male connector out of the female connector. Throughout the process, the operator applies force along the insertion direction of the male and female connectors, which is beneficial for operation in small and compact spaces, adapting to more usage scenarios and improving applicability.

[0014] Furthermore, the mounting structure includes a mounting plate; two mounting rings are fixed on the mounting plate; the mounting rings and the rotating rod are coaxial; the mounting rings are located on both sides of the locking protrusion; the rotating rod is rotatably mounted inside the mounting rings; the middle part of the mounting plate is rotatably connected to the housing. When the elasticity of the auxiliary rods at both ends of the rotating rod deviates, resulting in inconsistent rotational forces provided by the inclined sections at both ends of the rotating rod, the mounting plate will rotate to balance the forces applied on both sides of the rotating rod, thus avoiding uneven force applied by the operator due to inconsistent elasticity.

[0015] Furthermore, the mounting ring has a mounting notch; the mounting notch connects the inside of the mounting ring to the outside. The mounting notch facilitates the insertion of the rotating rod into the mounting ring.

[0016] Furthermore, the control panel is equipped with anti-slip texture.

[0017] Furthermore, the sliding structure includes a sliding groove and a sliding post; the sliding groove is opened on the operating plate, extending along the insertion direction of the male and female heads; the sliding post is fixed on the insert housing; the end of the sliding post away from the insert housing slides in conjunction with the sliding groove.

[0018] Furthermore, a metal pin is fixed on the housing; the pin is electrically connected to the corresponding cable core; the bottom wall of the slot is provided with a socket; a contact piece is fixed inside the socket; the contact piece is electrically connected to the corresponding cable core.

[0019] Furthermore, a guide bar is provided on the outer wall of the insert housing; a guide groove is provided on the side wall of the slot. When the male and female connectors are inserted, the guide bar and the guide groove slide together.

[0020] Furthermore, the control panel is flexible.

[0021] The beneficial effects of this invention are as follows: When the male and female connectors are inserted, the auxiliary structure restricts the rotation of the rotating rod, causing the locking protrusion to abut against the locking surface and locking the hanging block in the groove. Before the male and female connectors are separated, the auxiliary structure applies force along the insertion direction to drive the rotating rod to rotate, causing the locking protrusion to rotate away from the locking surface, thereby unlocking the hanging block. The direction of the locking protrusion of the rotating rod and the unlocking action of the hanging block are parallel to the insertion direction of the male and female connectors, which is beneficial for operation in a small and compact space and improves the connection efficiency of the male and female connectors.

[0022] Furthermore, when the elasticity of the auxiliary rods at both ends of the rotating rod deviates, resulting in inconsistent rotational forces provided by the inclined sections at both ends of the rotating rod, the mounting plate will rotate to a certain extent (along...). Figure 10 (in the direction of b), so that the force applied on both sides of the rotating rod tends to be balanced, avoiding uneven force applied by the operator due to inconsistent elasticity.

Detailed Implementation

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] An embodiment of the anti-loosening electromechanical equipment electrical connector of the present invention, such as... Figures 1 to 11As shown, the connector includes a male connector 100, a female connector 200, and a locking assembly. The male connector 100 includes a housing 110, which is fixed to the end of one section of cable. A metal pin 120 is fixed to the housing 110; the pin 120 is electrically connected to the corresponding cable core. The female connector 200 includes a sleeve 210, which is fixed to the end of another section of cable. A slot 220 is provided at the end of the sleeve 210 near the male connector 100; when the male connector 100 and female connector 200 are connected, the housing 110 is inserted into the slot 220. A insertion hole is provided on the bottom wall of the slot 220; a contact piece 230 is fixed inside the insertion hole; the contact piece 230 is electrically connected to the corresponding cable core. A guide strip is provided on the outer wall of the housing 110; a guide groove is provided on the side wall of the slot 220. When the male connector 100 and female connector 200 are inserted, the guide strip and guide groove slide together.

[0028] The locking assembly includes a groove 310, a hanging block 320, and a steel clip. Two grooves 310 are symmetrically arranged and are formed on the side wall of the slot 220. Two hanging blocks 320 are symmetrically arranged and are fixed to the outer side wall of the insert 110. The end face of the hanging block 320 near the female head 200 is designated as a mating surface 321. The mating surface 321 is an inclined surface that is inclined relative to the insertion direction of the male head 100 and the female head 200. The end face of the hanging block 320 away from the female head 200 is designated as a locking surface 322. The locking surface 322 is a plane perpendicular to the insertion direction. When the insert 110 is inserted into the slot 220, the hanging block 320 is inserted into the groove 310.

[0029] The steel clip includes a rotating rod 410 and an auxiliary structure; two rotating rods 410 are symmetrically arranged; the rotating rods 410 are elastic rods perpendicular to the insertion direction, and the two rotating rods 410 are parallel; the rotating rods 410 are located between the sleeve 210 and the insert 110; both ends of the rotating rods 410 are rotatably mounted on the sleeve 210 around an axis perpendicular to the insertion direction via an installation structure; the middle part of the rotating rod 410 is bent toward the center of the sleeve 210 to form a locking protrusion 411; the locking protrusion 411 is located on the side of the groove 310 near the male end 100. The installation structure includes a mounting plate 330; two mounting rings 331 are fixed on the mounting plate 330; the mounting rings 331 and the rotating rods 410 are coaxial; the mounting rings 331 are located on both sides of the locking protrusion 411; the rotating rods 410 are rotatably mounted inside the mounting rings 331; the middle part of the mounting plate 330 is rotatably connected to the sleeve 210. When the elasticity of the auxiliary rods 420 at both ends of the rotating rod 410 deviates, causing the rotational force provided by the inclined section 421 at both ends of the rotating rod 410 to be inconsistent, the mounting plate 330 will rotate to a certain extent (along the direction of rotation). Figure 10 The direction of rotation (b) ensures that the force applied to both sides of the rotating rod 410 tends to be balanced, avoiding uneven force applied by the operator due to inconsistent elasticity. The mounting ring 331 has a mounting notch 332; the mounting notch 332 connects the inside of the mounting ring 331 to the outside. The mounting notch 332 facilitates the insertion of the rotating rod 410 into the mounting ring 331.

[0030] When the male connector 100 and the female connector 200 are inserted, the auxiliary structure restricts the rotation of the rotating rod 410, causing the locking protrusion 411 to abut against the locking surface 322, locking the hanging block 320 within the groove 310. Before the male connector 100 and the female connector 200 are removed, the auxiliary structure applies force along the insertion direction to drive the rotating rod 410 to rotate, causing the locking protrusion 411 to rotate away from the locking surface 322, thereby unlocking the hanging block 320. The direction of the unlocking action of the locking protrusion 411 of the rotating rod 410 and the hanging block 320 is parallel to the insertion direction of the male connector 100 and the female connector 200, which facilitates operation in a small and compact space and improves the connection efficiency of the male connector 100 and the female connector 200.

[0031] Two auxiliary structures are provided, symmetrically located at both ends of the rotating rod 410. Each auxiliary structure includes an auxiliary rod 420 and an operating unit. Two auxiliary rods 420 are symmetrically located between the two rotating rods 410. Each auxiliary rod 420 corresponds to one rotating rod 410. The auxiliary rod 420 is an elastic rod, including an inclined section 421 and a parallel section 422. The inclined section 421 is located on the side of the parallel section 422 closest to the male connector 100. The inclined section 421 is inclined relative to the insertion direction, and the inclined sections 421 of the two auxiliary rods 420 of the same auxiliary structure form a V-shape with their openings facing the male connector 100. The parallel section 422 is parallel to the insertion direction. The inclined section 421 is fixedly connected to the corresponding rotating rod 410. The parallel sections 422 of the two auxiliary rods 420 of one auxiliary structure are fixedly connected by a U-shaped rod.

[0032] Before the male head 100 and the female head 200 are separated, the operating unit is used to apply force along the insertion direction to push the parallel section 422 and drive the inclined section 421 to rotate. The inclined section 421 of the two auxiliary rods 420 of the same auxiliary structure forms a V shape with the small end facing the male head 100, so as to drive the rotating rod 410 to drive the locking protrusion 411 to rotate and move away from the locking surface 322.

[0033] In this embodiment, the operating unit includes an operating plate 500; the operating plate 500 is provided with anti-slip texture. The operating plate 500 is elastic. The length direction of the operating plate 500 extends along the insertion direction of the male connector 100 and the female connector 200; the operating plate 500 is disposed on one side of the insert housing 110; the end of the operating plate 500 away from the female connector 200 is slidably mounted on the insert housing 110 along the insertion direction of the male connector 100 and the female connector 200 through a sliding structure; the sliding structure includes a sliding groove 520 and a sliding post 530; the sliding groove 520 is formed on the operating plate 500, extending along the insertion direction of the male connector 100 and the female connector 200; the sliding post 530 is fixed on the insert housing 110; the end of the sliding post 530 away from the insert housing 110 and the sliding groove 520 are slidably engaged.

[0034] The operating plate 500 has a U-shaped plate 510 with an opening facing the insert housing 110 fixed at one end near the female head 200. During the process of inserting one end of the insert housing 110 into the slot 220, the mating surface 321 of the hanging block 320 abuts against the locking protrusion 411, and the rotating rod 410 undergoes elastic deformation to push the locking protrusion 411 open. When the hanging block 320 passes the locking protrusion 411 and enters the groove 310, the locking protrusion 411 returns to its original position and abuts against the locking surface 322 of the hanging block 320, locking the hanging block 320 in the groove 310. During this process, the parallel segments 422 of the two auxiliary rods 420 of the same auxiliary structure are inserted into the opening of the U-shaped plate 510. Before the male connector 100 and female connector 200 are separated, the operator pushes the operating plate 500 away from the female connector 200 by hand along the insertion direction of the male connector 100 and female connector 200. When the U-shaped plate 510 moves to the junction of the inclined section 421 and the parallel section 422, the U-shaped plate 510 applies a thrust along the insertion direction to the inclined section 421, causing the inclined section 421 to rotate. This causes the inclined sections 421 of the two auxiliary rods 420 of the same auxiliary structure to form a V-shape with the smaller end facing the male connector 100, thereby driving the rotating rod 410 to rotate the locking protrusion 411 away from the locking surface 322, thus unlocking the hanging block 320. Then, the operator pulls the male connector 100 and female connector 200 by hand, allowing the male connector 100 to be pulled out of the female connector 200. Throughout the process, the operator applies force along the insertion direction of the male connector 100 and female connector 200, which is beneficial for operation in small and compact spaces, adapts to more usage scenarios, and improves applicability.

[0035] In conjunction with the above embodiments, the working principle and operation process of the present invention are as follows: During use, when one end of the insert shell 110 is inserted into the slot 220, the mating surface 321 of the hanging block 320 abuts against the locking protrusion 411, and the rotating rod 410 undergoes elastic deformation to push the locking protrusion 411 away. When the hanging block 320 passes the locking protrusion 411 and enters the groove 310, the locking protrusion 411 resets and abuts against the locking surface 322 of the hanging block 320, locking the hanging block 320 in the groove 310. During this process, the parallel segments 422 of the two auxiliary rods 420 of the same auxiliary structure are inserted into the opening of the U-shaped plate 510. Before the male connector 100 and the female connector 200 are separated, the operating plate 500 is pushed away from the female connector 200 by hand along the insertion direction of the male connector 100 and the female connector 200. When the U-shaped plate 510 moves to the junction of the inclined section 421 and the parallel section 422, the U-shaped plate 510 applies a thrust along the insertion direction to the inclined section 421 (along the insertion direction). Figure 6(in the direction of a), causing the inclined section 421 to rotate, and causing the inclined sections 421 of the two auxiliary rods 420 of the same auxiliary structure to form a V shape with the smaller end facing the male head 100, so as to drive the rotating rod 410 to drive the locking protrusion 411 to rotate and move away from the locking surface 322, thereby unlocking the hanging block 320. Then, the male head 100 and the female head 200 are pulled by hand, so that the male head 100 is pulled out from the female head 200. Throughout the process, the operator's hand applies force along the insertion direction of the male head 100 and the female head 200, which is conducive to operation in a small and compact space, adapts to more usage scenarios, and improves applicability. When the elasticity of the auxiliary rods 420 at both ends of the rotating rod 410 deviates, resulting in inconsistent rotational force provided by the inclined section 421 at both ends of the rotating rod 410, the mounting plate 330 will generate a certain rotation (along the direction of a). Figure 10 (in the direction of b), so that the force applied on both sides of the rotating rod 410 tends to be balanced, avoiding uneven force applied by the operator due to inconsistent elasticity.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
