Description

Technical Field

[0001] The invention belongs to the field of connectors, and in particular relates to an anti-detachment connector for outdoor use. Background Art

[0002] Based on the prior art, it is found that when the existing connector is used in an outdoor environment, the cable is frequently dragged due to work requirements, which easily causes twitching between the male pin core and the female pin core, and the locking structure of the existing connector is too simple, so that during the dragging process, the dragging force on the cable as a whole will be transmitted to the male pin core and the female pin core, and then the male pin core and the female pin core are likely to have poor contact, affecting the normal use of electrical equipment, and in an outdoor environment, the movement of the connector is easily blocked by obstacles, which easily causes the entire connector to be separated by external forces, thereby affecting the normal use and safety performance of the overall connector;

[0014] Optionally, a hexagonal protrusion is fixedly connected to the outer ring surface of the threaded sleeve.

[0015] The advantages and positive effects of the present invention are:

[0016] (1) By observing the vertical surface set on each grounding ring, the vertical surfaces on the two grounding rings are aligned, and then the locking sleeve I and the locking sleeve II are docked and locked, so that the male pin core and the female pin core can be docked and the two cables can be connected. In addition, through the sealing ring set on the inner side of the outer shell II, the outer shell II and the outer shell I are more tightly connected, thereby further improving the stability and sealing of the connection between the male pin core and the female pin core.

[0017] (2) The cable is moved by rotating the two limit rods and the cable is limited so that the cable changes from an initial straight line to an S shape. At the same time, the ratchet is limited by the top rod, so that the disc, the two limit rods and the ratchet maintain their status quo under the limiting action of the top rod, thereby keeping the cable in an S shape.

[0018] (3) The dragging force generated on the cable is dispersed by two limit rods and transmitted to the disc. At this time, the ratchet is limited by the push rod, so that the dragging force transmitted to the disc is further dispersed and weakened, reducing the possibility of the male and female needle cores loosening and detaching. The ratchet and the push rod are used for energy absorption and buffering, and the force is further dispersed and weakened by the limit rod, the disc and the elastic member I. After the ratchet squeezes the push rod, the push rod can still be rotated and reset by the elastic force of the elastic member II, thereby limiting the ratchet again, so that the cable can still form a curved shape.

[0019] (4) The rotation of the baffle is blocked by the notch at the bottom of the cylinder, thereby further absorbing and buffering the drag force transmitted when the cable is dragged. When the drag force is greater than the resistance of the cylinder to the baffle, the baffle will detach from the notch at the bottom of the cylinder. At this time, the round rod and the cylinder rotate to trigger the torque sensor, and transmit the signal to the alarm device installed in the cylinder, so that the alarm device installed in the cylinder operates and sends an alarm signal, thereby reminding the on-site staff that the drag force of the cable is too large and there is a risk of the male and female needle cores being separated, thereby achieving the purpose of dispersing and weakening the drag force generated when the cable is dragged, and allowing the cable to be buffered, thereby reducing the drag force transmitted to the male and female needle cores, causing the male and female needle cores to become loose and separated, thereby effectively ensuring the normal use of electrical equipment.

[0020] (5) By twisting the threaded sleeve, the threaded sleeve rotates along the thread of the outer ring surface of the shell II and moves to the right, so that the four filters arranged in an annular shape and at equal intervals on the shell II are exposed to the outside, allowing the outside air to enter the locking sleeve II, so that the heat generated by the male and female needle cores after power is turned on can be quickly dissipated, thereby achieving cooling treatment of the male and female needle cores.

[0041] It also includes a baffle 2051, which is a metal spring. The lower part of the round rod 205 is rotatably connected with the baffle 2051, and a notch for accommodating the baffle 2051 is opened at the bottom of the cylinder 203. A torque sensor is installed between the round rod 205 and the cylinder 203.

[0042] When the outdoor anti-disconnection connector is in use: the two grounding rings 17 are removed in advance, and one end of the two cables is passed through the dust plug 11 and the wire clamp 14 in each grounding ring 17, and then the cables are limited by the dust plug 11 and the wire clamp 14, and then one end of the two cables is connected to a male pin core 15 and a female pin core 25, and then the two grounding rings 17 are respectively installed on the locking sleeve Ⅰ13 and the shell Ⅱ21, and then the shell Ⅰ12 and the shell Ⅱ21 are manually held to move the shell Ⅰ12 and the shell Ⅱ21 toward each other, and by observing the vertical surface 171 set on each grounding ring 17, the vertical surfaces 171 on the two grounding rings 17 are aligned, so that the locking sleeve Ⅰ13 and the locking sleeve Ⅱ24 are docked and locked. At this time, the shell Ⅰ1 2 moves to drive the locking sleeve I13 to move, and the locking sleeve I13 moves to drive the male needle core 15 and the insulating fixing ring 16 to move synchronously, and at the same time, the outer shell II 21 moves to drive the locking sleeve II 24 to move, and the locking sleeve II 24 moves to drive the female needle core 25 to move, so that the male needle core 15 is docked with the female needle core 25, and at the same time, the locking sleeve I13 is docked and locked with the locking sleeve II 24, that is, the limiting portion 242 of the locking sleeve II 24 is engaged with the protrusion 131 of the locking sleeve I13, so that the male needle core 15 is docked with the female needle core 25, and the two cables are connected, and the outer shell II 21 is more tightly connected with the outer shell I12 through the sealing ring arranged on the inner side of the outer shell II 21, so as to further improve the stability and sealing of the connection between the male needle core 15 and the female needle core 25.

[0043] The initial positions of the two clamps 201 are respectively inserted into the groove I on the shell II 21 and the groove II of the grounding ring 17 on the right, and the initial position of the baffle 2051 is not inserted into the notch opened at the bottom of the cylinder 203. When the existing connector is used in an outdoor environment, the cable is often dragged due to work needs, which easily causes twitching between the male needle core 15 and the female needle core 25. In addition, the locking structure of the existing connector is too simple, so that during the dragging process, the dragging force on the entire cable will be transmitted to the male needle core 15 and the female needle core 25, and then the male needle core 15 and the female needle core 25 are likely to have poor contact, which affects the normal use of electrical equipment. In addition, in an outdoor environment, the movement of the connector is easily blocked by obstacles, which easily causes the entire connector to be separated by external forces. Phenomenon, thereby affecting the normal use and safety performance of the overall connector. To solve the above problem, after the male needle core 15 and the female needle core 25 are connected, the upper cover 204 is first removed from the cylinder 203, and then the cable connected to the female needle core 25 is pulled, and the cable is placed in the cylinder 203, passing through the entrance and exit of the cylinder 203, and the cable is supported by the upper edge of the disk 206, and the cable is located between the two limit rods 208, and then the two limit rods 208 are manually twisted clockwise from the top down as a reference, so that the two limit rods 208 rotate and each drive a guide wheel 2081 to rotate and move, and then the two limit rods 208 rotate to drive the cable to move, and the cable is limited, so that the cable changes from the initial straight line to an S shape, as shown in FIG. Figure 7 As shown, the two limiting rods 208 rotate to drive the disc 206 to rotate, the disc 206 rotates to drive the round rod 205 to rotate, the round rod 205 rotates to drive the baffle 2051 to rotate, and the disc 206 rotates to drive the elastic member I 207 to rotate, so that the elastic member I 207 accumulates force, and the ratchet 209 is limited by the top rod 212 at the same time, so that the disc 206, the two limiting rods 208 and the ratchet 209 maintain the status quo under the limiting action of the top rod 212, so that the cable maintains an S shape, and then the baffle 2051 is inserted into the groove at the bottom of the cylinder 203, so that the cable changes from the initial straight line to the S shape and maintains the S shape.

[0044] When the cable is blocked by external force during the dragging process, the dragging force on the entire cable will be transmitted to the male needle core 15 and the female needle core 25, which may easily lead to the loosening of the connection between the male needle core 15 and the female needle core 25, or even the separation. By pre-transforming the cable into an S shape, when the cable is dragged, the dragging force generated on the cable is dispersed by the two limiting rods 208, and the dragging force is transmitted to the disc 206. At this time, the ratchet 209 is limited by the push rod 212, so that the dragging force transmitted to the disc 206 is further dispersed and weakened, reducing the possibility of loosening and separation of the male needle core 15 and the female needle core 25. If the cable is instantly dragged by external factors and the dragging force is greater than that of the push rod 212 When the ratchet 209 generates resistance, the ratchet 209 will rotate quickly and instantly squeeze the push rod 212, so that the push rod 212 rotates with the connecting rod 211 as the axis, and then the push rod 212 no longer limits the ratchet 209, so that the ratchet 209 and the push rod 212 are used for energy absorption and buffering, and the force is further dispersed and weakened by the limiting rod 208, the disk 206 and the elastic member I 207, and after the ratchet 209 squeezes the push rod 212, the push rod 212 can still be rotated and reset by the elastic force of the elastic member II 213, so as to limit the ratchet 209 again, so that the cable can still form a curved shape; at the same time, the two limiting rods 208 rotate to drive the disk 206 to rotate, and the disk 206 rotates The elastic member I 207 is driven to rotate, and the disk 206 drives the round rod 205 to rotate. The round rod 205 drives the baffle 2051 to rotate. Since the baffle 2051 has been pre-stuck in the notch at the bottom of the cylinder 203, when the baffle 2051 rotates, it will be blocked by the notch at the bottom of the cylinder 203, thereby further absorbing and buffering the drag force transmitted when the cable is dragged. When the drag force is greater than the resistance of the cylinder 203 to the baffle 2051, the baffle 2051 will be deformed and detached from the notch at the bottom of the cylinder 203. At this time, the rotation between the round rod 205 and the cylinder 203 will trigger the torque sensor, and transmit the signal to the alarm provided in the cylinder 203, so that the cylinder 203 The built-in alarm sends out an alarm signal to remind the on-site staff that the dragging force of the cable is too large and there is a risk of the male needle core 15 and the female needle core 25 being detached. At this time, the on-site staff will perform maintenance to reduce the risk of the male needle core 15 and the female needle core 25 being detached, thereby dispersing and weakening the dragging force generated when the cable is dragged, and allowing the cable to be buffered, thereby reducing the dragging force transmitted to the male needle core 15 and the female needle core 25, causing the male needle core 15 and the female needle core 25 to become loose and detached, thereby effectively ensuring the normal use of electrical equipment, and when releasing the limit on the cable, it is only necessary to pull the pull rod 214 and the baffle 2051, thereby improving the convenience of use.

[0045] Embodiment 2: Based on Embodiment 1, according to Figure 10-11As shown, it also includes a heat dissipation system; the heat dissipation system is connected to the shell II 21; the heat dissipation system includes a threaded sleeve 22, a filter 23 and a pick 241; four through grooves 121 are arranged equidistantly in an annular manner on the shell I 12; the outer ring surface of the shell II 21 is provided with threads; the outer ring surface of the shell II 21 is spirally connected to the threaded sleeve 22; four filters 23 are fixedly connected to the shell II 21 in an annular manner at equal distances; four picks 241 are fixedly connected to the inner side of the locking sleeve II 24, and the picks 241 are metal springs.

[0046] A hexagonal protrusion is fixedly connected to the outer ring surface of the threaded sleeve 22, which is convenient for manually holding the threaded sleeve 22 and driving the threaded sleeve 22 to rotate.

[0047] When the male needle core 15 and the female needle core 25 are cooled: since the male needle core 15 and the female needle core 25 will generate heat after being energized, and will continue to generate heat during operation, and the existing connector will tightly wrap the male needle core 15 and the female needle core 25, resulting in extremely poor heat dissipation effect, causing the temperature of the male needle core 15 and the female needle core 25 to gradually increase, and this phenomenon will be more obvious in the high temperature environment outdoors. The released heat generated by long-term use cannot be released, which is easy to cause sudden safety hazards. After the male needle core 15 and the female needle core 25 are connected, the threaded sleeve 22 is manually twisted to rotate along the thread of the outer ring surface of the shell II 21 and move to the right, so that the four filters 23 arranged equidistantly in an annular manner on the shell II 21 are exposed to the outside, so that the outside air can enter the locking sleeve II 24, and since the filter 23 is aligned with the through groove on the locking sleeve II 24, the locking sleeve II The through groove on 24 is aligned with the through groove II on the locking sleeve I13, and the through groove II on the locking sleeve I13 is aligned with the through groove 121 on the shell I12, so that the heat generated by the male needle core 15 and the female needle core 25 after being energized can flow out through the through groove on the locking sleeve I13, the through groove on the locking sleeve II24, the filter 23 and the through groove 121, so that the heat generated by the male needle core 15 and the female needle core 25 after being energized can be quickly dissipated, thereby achieving cooling treatment for the male needle core 15 and the female needle core 25, and when used in a rainy environment, by tightening the threaded sleeve 22 and the shell II21, the four filter screens 23 are wrapped in the shell II21. Since the temperature outside is lowered on rainy days, the male needle core 15 and the female needle core 25 can be cooled by natural heat exchange between the exchanger as a whole and the external environment, and rainwater can be prevented from entering the shell I12 and the shell II21.

[0048] When it is necessary to separate and remove the male needle core 15 and the female needle core 25, the locking sleeve I13 is twisted, and the locking sleeve I13 rotates to drive the protrusion 131 to rotate. The protrusion 131 rotates and touches the paddle 241 on the locking sleeve II24 and is blocked by the paddle 241. At this time, the locking sleeve I13 is manually twisted, and the blocking force of the paddle 241 on the protrusion 131 will be fed back to the worker's hand, reminding the worker that the protrusion 131 is gradually separated from the paddle 241. After the protrusion 131 is separated from the limit of the paddle 241, the worker's hand will obviously feel that the resistance to rotating the locking sleeve I13 becomes smaller, and then the locking sleeve I13 is pulled out from the locking sleeve II24, thereby separating and removing the male needle core 15 and the female needle core 25, so that it is convenient for manual work to quickly separate the male needle core 15 and the female needle core 25.

[0049] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, it should be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
