Description

Technical Field

[0001] The invention relates to the technical field of dairy cattle breeding electrification equipment, in particular to an adaptive quick plug-in electrical connector. Background Art

[0002] In dairy farming, a breast pump is often used to suck milk from cows. Before sucking milk, the plug at the end of the breast pump needs to be inserted into the plug connector that has been powered on. In the prior art, the plug connector includes an insulating base, an insulating shell is connected to the insulating base, and an elastic contact is fixedly connected between the insulating shell and the insulating base. The plug is directly inserted into the clamping opening of the contact with force. The upper end of the plug is hemispherical, and the outer diameter of the clamping opening below the hemispherical shape is slightly smaller than the outer diameter of the full circle of the plug. The plug is inserted into the insulating base from bottom to top through the clamping opening with force. The limit step at the lower end of the plug contacts the lower side of the insulating base and the insulating shell, and the plug is clamped by the elasticity of the clamping opening. After sucking milk, the plug is pulled downward. The structure of the plug connector utilizes the opening of the clamping opening to make the contact piece elastic, so as to clamp the plug. The breast pump is frequently powered on and off, and the clamping opening is likely to become larger and unable to recover, so that the contact piece cannot clamp the plug, and the plug is likely to slip off. Even if the plug does not slip off, there will be poor contact between the plug and the contact piece, and normal milk suction cannot be performed, thereby affecting milk production efficiency. Summary of the invention

[0003] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0004] In view of the above and / or existing problems in connecting the plug-in connector of a breast pump, the present invention is proposed.

[0005] Therefore, the problem to be solved by the present invention is that the clamping opening in the prior art is easily enlarged and cannot be restored, so that the contact piece cannot clamp the plug, resulting in poor contact; the present invention makes the plug and the conductive part fit tightly by continuous insertion of the plug. When the plug is inserted to the set highest position, the plug and the conductive part are adaptively connected together, the plug will not slip off, the reliability of the plug-in connector connection is improved, and poor contact is not easy.

[0049] In the present application, the lifting slider 217, the power transmission member 204, the clamping transmission block 216, the clamping block 215 and the conductive member 202 are made of the same material; when the lifting slider 217 moves upward, the lifting slider 217 drives the clamping transmission block 216 to move upward via the connecting rod 214, and when the clamping transmission block 216 moves upward, it drives the clamping block 215 to move toward the direction of the power transmission part 101a. When the lifting slider 217 moves to the highest position, that is, the lifting slider 217 cannot continue to move upward, the opposite sides of the two clamping blocks 215 are just in contact with the outer periphery of the power transmission part 101a, thereby increasing the contact area between the power transmission part 101a and the conductive member 202 and improving the reliability of conduction.

[0050] Example 3 Reference Figure 8 to Figure 10 , Fig.15 and Fig.16 , which is the second embodiment of the present invention, based on embodiment 2, this embodiment provides an adaptive quick-plug electrical connector. When the plug 100 is inserted to the highest position, the plug 100 and the conductive member 202 are connected together to avoid poor contact.

[0051] Specifically, a lifting transmission block 219a is fixedly connected to the front side of the transmission rack 219. The lifting transmission block 219a has a third inclined surface on one side and the front end in the left-right direction. The front end of the lifting transmission block 219a is just slidably connected to a lifting limit block 222 that can move forward and backward through the third inclined surface. A vertical slide groove vertically arranged in the front-back direction is opened on the conductive member 202. The lifting limit block 222 just slides forward and backward along the vertical slide groove. When the screw shaft 213 drives the transmission rack 219 to move horizontally in the left-right direction as the lifting slider 217 moves upward, the lifting limit block 222 moves forward under the action of the lifting transmission block 219a. A movable sinker is opened on the lifting limit block 222. Slot 222a, the lifting limit block 222 is just slidably connected to the limit block 229 for limiting the horizontal movement of the lifting transmission block 219a through the movable sink groove 222a, and the inner end of the limit block 229 is connected to the second return spring 228, and the end of the second return spring 228 away from the limit block 229 is connected to the lifting limit block 222. When the limit block 229 is in the conductive member 202, the second return spring 228 is in a compressed state; when the limit block 229 moves forward and leaves the conductive member 202, the limit block 229 slides out of the lifting limit block 222, and the rear side of the limit block 229 contacts the front side of the conductive member 202, the lifting limit block 222 stops moving in the front and rear directions, and the limit transmission member stops rotating.

[0052] Among them, a second slide rail is fixed on the lifting transmission block 219a at the third inclined surface, and the lifting limit block 222 has a fourth inclined surface 229a on the side opposite to the lifting transmission block 219a. A second slide groove is opened on the lifting limit block 222 at the fourth inclined surface 229a, and the lifting limit block 222 is slidably connected to the lifting transmission block 219a through the second slide groove; when the transmission rack 219 moves to the right, the transmission rack 219 drives the lifting transmission block 219a to move to the right, and the lifting transmission block 219a pushes the lifting limit block 222 to move up through the third inclined surface, and the limit block 229 does not leave the vertical slide. When the lifting slider 217 moves to the highest position, the lower side of the limit block 229 is flush with the front side of the conductive member 202, and the limit block 229 slides out under the action of the second return spring 228, and the lifting limit block 222 stops moving. As long as the limit block 229 is not pushed into the movable groove 222a, under the action of the second slide groove and the second slide rail, the lifting transmission block 219a is fixed, the transmission rack 219 stops moving, the limit rotating member 207 stops rotating, and the arc segment of the jack 207b and the arc segment of the limit rotating sleeve are staggered.

[0053] Example 4 Reference Figure 5 , Figure 7 and Figure 10 to Figure 13 , which is the second embodiment of the present invention, based on embodiment 2, this embodiment provides an adaptive quick-plug electrical connector, which can achieve rapid sliding of the plug 100 when milking is finished.

[0054] Specifically, the front end of the conductive member 202 is slidably connected to a plug removal block 201 that can move forward and backward, and a sliding hole 201b that can slide along the lifting limit block 222 is opened at the rear end of the plug removal block 201, and a pressing groove 201c is opened on the plug removal block 201 on one side of the sliding hole 201b in the left and right directions. The front end of the limit block 229 away from the second return spring 228 has a fourth inclined surface 229a. When the limit block 229 slides out of the lifting limit block 222, the fourth inclined surface 229a just fits on the plug removal block 201 at the pressing groove 201c. When the plug removal block 201 moves backward, the plug removal block 201 pushes the limit block 229 into the lifting limit block 222 via the pressing groove 201c and the second inclined surface.

[0055] After the milking is finished, when the plug 100 needs to be unplugged, the plug removal block 201 is moved backward, that is, moved in the direction of the lifting limit block 222. The plug removal block 201 pushes the limit block 229 into the movable sink groove 222a through the pressing groove 201c and the second inclined surface. The lifting slider 217 moves downward under the action of the first return spring 221. The lifting slider 217 drives the clamping transmission block 216 to move downward through the connecting rod 214, and the spiral shaft 213 moves downward at the same time. The lifting slider 217 directly drives the plug 100 to move downward through the electric transmission part. The spiral shaft 213 rotates at the same time under the action of the transmission column 227. The spiral shaft 213 drives the active rotating member 224 to rotate, and the transmission The movable rack 219 moves left, the limit rotating member 207 rotates, and the two clamping blocks 215 move away from each other under the drive of the clamping transmission block 216. The two clamping blocks 215 simultaneously release the lower part of the power transmission part 101a. When the plug 100 just starts to move down, the limit connecting sleeve 102 cannot move down due to the misalignment of the plug hole and the arc segment of the plug part. At the beginning, only the middle connecting part 101b moves down. When the limit rotating member 207 rotates to align the plug hole and the limit connecting sleeve 102, the limit connecting sleeve 102 quickly moves down through the plug hole under the action of the pressing plate 209, so that the plug 100 quickly slides down and leaves the conductive member 202.

[0056] Specifically, an insulating rotating rod 203 is rotatably connected to the insulating shell 301, one end of the insulating rotating rod 203 extending into the insulating shell 301 is threadedly connected to the plug removal block 201, and a plurality of operating handles 203a for easy rotation are arranged on the outer periphery of the insulating rotating rod 203 outside the insulating shell 301.

[0057] When the plug removal block 201 needs to be moved backward, the insulating rotating rod 203 is rotated by operating the handle 203a, and the insulating rotating rod 203 drives the plug removal block 201 to move backward, that is, the plug removal block 201 moves in the direction of the lifting limit block 222. The plug removal block 201 pushes the limit block 229 into the lifting limit block 222 through the pressing groove 201c and the second inclined surface, so as to facilitate the rapid removal of the plug 100.

[0058] Furthermore, at least one positioning step 201a is fixed on the outside of the plug removal block 201, and a positioning column 202a is fixed on the conductive member 202 outside the positioning step 201a. A positioning plate 210 is fixedly connected to the upper side of the positioning column 202a. In the initial state, the front side of the positioning step 201a abuts against the rear side of the positioning plate 210, thereby realizing the positioning of the plug removal block 201 in the initial state; when the plug 100 is pulled out from the conductive member 202 and the plug removal block 201 needs to be restored to the state before the plug 100 is inserted into the conductive member, the insulating rotating rod 203 is rotated in the reverse direction by the operating handle 203a, and the insulating rotating rod 203 drives the plug removal block 201 to move forward. When the front side of the positioning step 201a abuts against the positioning plate 210, the rotation of the operating handle 203a is stopped.

[0059] The directions in this application are based on the main view, the front-to-back direction is the direction perpendicular to the paper surface, and the left-to-right direction is the horizontal direction perpendicular to the front-to-back direction.
