Detailed Implementation
[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0018] like Figures 1 to 12 As shown, this medical wiring harness electrical connection terminal of the present invention includes a first connection terminal 1, a second connection terminal 2, and a mating member 3. The first connection terminal 1 and the second connection terminal 2 are electrically connected within the mating member 3, which provides a relatively stable connection environment for the first connection terminal 1 and the second connection terminal 2. This ensures that the first connection terminal 1 and the second connection terminal 2 can be connected in two different states. Due to the high volume of people in hospitals, wiring harnesses can be moved by people, causing the connectors to break off from the equipment. If this is not detected in time, it can prevent patients from undergoing examinations, and in severe cases, it can prevent patients from receiving the necessary treatment.
[0019] One connection method for the first connecting terminal 1 and the second connecting terminal 2 is a direct connection. The rubber ring 4 provides friction, ensuring the stability of the connection between the two terminals and preventing easy separation that could interrupt the electrical connection. However, this connection structure cannot prevent separation of the first connecting terminal 1 and the second connecting terminal 2 when subjected to significant external force. Therefore, an alternative connection structure is required.
[0020] The second connection state is achieved by rotating the second connecting terminal 2 or the mating member 3 to keep the second contact body 5 close to the first contact body 6. This causes the second connecting terminal 2 to push the positioning member 8, which is pressed by the elastic member 7, to rotate. The positioning protrusion 9 of the positioning member 8 is kept in the annular groove 10 for restriction, thereby restricting the position of the first connecting terminal 1 and the second connecting terminal 2 and preventing external force from separating the first connecting terminal 1 and the second connecting terminal 2.
[0021] By setting two different connection states, it can be used in different environments. The first connection state can be used for electrical connection terminals that need to be plugged and unplugged frequently, while the second connection state can be used for electrical connection terminals that do not need to be plugged and unplugged for a long time, especially in locations with high traffic volume, thus avoiding the electrical connection from being broken due to external pulling.
[0022] The first connecting terminal 1 is provided with a first contact body 6, and the first contact body 6 is provided with an annular groove 10. The first contact body 6 is provided with a contact section 11 and an insertion section 12. The second contact body 5 is provided with a contact hole 13 that mates with the contact section 11, and the length of the contact hole 13 is greater than the length of the contact section 11. The annular groove 10 is provided on the insertion section 12, and the insertion section 12 is provided with a first inclined surface 14. The first contact body 6 is provided with a second inclined surface 15, which is used to push the rubber ring 4.
[0023] The second connecting terminal 2 is connected to the first connecting terminal 1. The second connecting terminal 2 has a second contact body 5 in the middle, and the second contact body 5 is connected to the first contact body 6.
[0024] The second connecting terminal 2 is provided with a rotating part 16 and an insertion part 17. The insertion part 17 is provided with a first threaded part 18 and a pushing inclined surface 19. The pushing inclined surface 19 cooperates with the guiding inclined surface 20.
[0025] A retainer 22 is provided in the first mounting hole 21. The retainer 22 has a first internal thread 23 in the middle that mates with the first threaded portion 18. The retainer 22 has a second threaded portion 24 on the outside. The inner wall of the first mounting hole 21 has a second internal thread 25 that mates with the second threaded portion 24.
[0026] A symmetrically arranged positioning block 26 is provided on the insertion part 17. A positioning hole 27 is provided in the middle of the positioning block 26, and a positioning pin 28 is provided in the positioning hole 27. The positioning block 26 is mounted on the insertion part 17 by means of the positioning pin 28. The positioning block 26 can prevent the second connecting terminal 2 from rotating out of the first mounting hole 21.
[0027] The retainer 22 consists of a mounting part 29 and a disc body 30. A second threaded part 24 is provided on the outer wall of the mounting part 29, and a first internal thread 23 is provided in the middle of the mounting part 29. The disc body 30 is mounted on the mating part 3 by a fixing pin 31.
[0028] The docking member 3 is disposed on the second connecting terminal 2. The positioning member 8 and the elastic member 7 are symmetrically arranged inside the docking member 3. The middle of the positioning member 8 is hinged to the docking member 3 through the first hinge shaft 32. The elastic member 7 pushes one end of the positioning member 8 to keep the other end of the positioning member 8 away from the annular groove 10.
[0029] The first connecting terminal 1 is inserted into the middle of the docking member 3 and docks with the second connecting terminal 2. The second connecting terminal 2 is rotated to keep the second contact body 5 close to the first contact body 6. The second connecting terminal 2 pushes one end of the positioning member 8 and keeps the other end of the positioning member 8 in the annular groove 10 to restrict the second contact body 5.
[0030] The connecting member 3 has a first mounting hole 21, a second mounting hole 33, a first through hole 34, and a second through hole 35 in the middle. The first mounting hole 21 communicates with the second mounting hole 33 through the first through hole 34 and the second through hole 35. A symmetrically arranged movable chamber 36 is provided at the first through hole 34, and the positioning member 8 is disposed in the movable chamber 36. The inner diameter of the first mounting hole 21 is larger than the inner diameter of the first through hole 34 and the second through hole 35.
[0031] The second mounting hole 33 contains a rubber ring 4 and a limiting ring 37. A limiting groove 38, which mates with the limiting ring 37, is also present in the second mounting hole 33. The inner diameter of the limiting groove 38 is larger than the inner diameter of the second mounting hole 33. The limiting ring 37 is broken in the middle, forming small holes 39 at both ends. A connection gap 40 is formed at the break point. During installation, clamps are placed in the small holes 39 and clamped to eliminate the connection gap 40, allowing the ring to pass through the second mounting hole 33 and be placed in the annular groove 10. A third through hole 41 is formed in the middle of the rubber ring 4, and a through area 42 is formed in the middle of the limiting ring 37.
[0032] The activity room 36 is provided with a first hinge hole 43 and a second hinge hole 44. The first hinge shaft 32 is set in the first hinge hole 43 and the second hinge shaft 58 is set in the second hinge hole 44.
[0033] The positioning component 8 consists of a pushing end 45 and a positioning end 46. The pushing end 45 is provided with a pressure surface 47, a clearance surface 48 and a guide slope 20, and the positioning end 46 is provided with a clearance opening 49, a positioning protrusion 9 and a blocking surface 50.
[0034] A blocking body 51 is provided in the activity chamber 36 to cooperate with the blocking surface 50. The blocking surface 50 has a contact surface 52 that cooperates with the blocking surface 50, and an active gap 53 is formed between the contact surface 52 and the blocking surface 50. The blocking body 51 is used to limit the rotation angle of the positioning member 8 and prevent the elastic member 7 from excessively pressing the positioning member 8 to rotate.
[0035] The activity chamber 36 is provided with a blocking block 54. The elastic element 7 is composed of a connecting section 55 and a spiral section 56 and a pressure section 57 symmetrically arranged at both ends of the connecting section 55. The connecting section 55 is in contact with the blocking block 54, and the pressure section 57 is in contact with the pressure surface 47. A second hinge shaft 58 is provided in the middle of the spiral section 56. The second hinge shaft 58 hinges the elastic element 7 in the activity chamber 36.
[0036] When the first connecting terminal 1 is not inserted, the elastic element 7 pushes the pushing end 45 downward, keeping the blocking surface 50 in contact with the contact surface 52. When the first connecting terminal 1 is inserted, it will not affect the positioning element 8. When positioning is required, the second connecting terminal 2 or the mating element 3 can be rotated, so that the second connecting terminal 2 moves closer to the first connecting terminal 1 under the cooperation of the first threaded part 18 and the first internal thread 23. The contact section 11 is kept moving within the contact hole 13, so that the pushing inclined surface 19 pushes the guiding inclined surface 20 upward, compressing the elastic element 7, keeping the contact surface 52 separated from the blocking surface 50. The positioning protrusion 9 enters the annular groove 10 to restrict the position of the first connecting terminal 1, preventing the separation of the first connecting terminal 1 and the second connecting terminal 2.
[0037] An observation gap 59 is formed between the mating part 3 and the rotating part 16, which allows it to be seen at a glance whether the electrical connection terminal is in the first state or the second state. When the observation gap 59 is present, it is in the first state, and when the observation gap 59 disappears, it is in the second state, which is convenient for observation.
[0038] 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 and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
