Description

Technical Field

[0001] This utility model relates to the field of medical end cap technology, specifically to an electrically charged end cap. Background Technology

[0002] In existing charged caps, the structure that maintains the electrical connection between the charged cap and the pin when the pin is inserted into the charged cap is a spring and a metal contact block. The spring force pushes the metal contact block to maintain the connection with the pin. However, due to the size limitation of the cap, the metal contact block is only located on one side of the pin. Therefore, when the pin moves, the varying degrees of contact between the metal contact block and the pin cause a significant change in resistance when the charged cap and the pin are engaged. This makes it difficult to accurately control the resistance during use and is very inconvenient. Utility Model Content

[0028] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] Combined with appendix Figure 1-5 A live end cap includes a housing 1, with a channel 4 inside the housing 1, the channel 4 extending through the housing 1 and used for inserting a pin. The housing 1 has an opening in the radial direction of the channel 4 for installing a connecting accessory 3, the opening extending into and communicating with the channel 4. The connecting accessory 3 is fixedly installed in the opening, and a clamp 2 is fixedly installed inside the connecting accessory 3. When the connecting accessory 3 is installed in the opening, the clamp 2 inside the connecting accessory 3 is located in the channel 4, and the pin is inserted into the channel 4 and continuously contacts the clamp 2, thereby achieving a stable electrical connection between the clamp 2 and the pin.

[0031] The housing 1 has cavities facing different directions, each with an outward opening. Each cavity includes an accessory cavity 5 and a pin cavity 6. The accessory cavity 5 is radially positioned on the side of the channel 4. The accessory cavity 5 houses the connecting accessory 3, which is installed within the housing 1. An opening is located at the bottom of the accessory cavity 5. Part of the connecting accessory 3 is fixed within the housing 1 at the bottom of the accessory cavity 5, while the other part resides within the accessory cavity 5. The accessory cavity 5 assists in connecting the connecting accessory 3 to external devices. Through its limiting function, the accessory cavity 5 ensures a stable connection between the external device and the connecting accessory 3. Preferably, the opening is located at the center of the accessory cavity 5, allowing the external device to be securely inserted into the accessory cavity 5 after the connecting accessory 3 is installed.

[0032] The pin cavity 6 is connected and disposed in the axial direction of the channel 4, and is located at the end of the channel 4. The pin is inserted into the channel 4 through the pin cavity 6. The channel 4 is preferably located at the center of the pin cavity 6. The pin cavity 6 is used to assist the pin in being inserted into the channel 4. When the pin is inserted into the channel 4, a support member is provided on the pin. The structure and shape of the support member correspond to the pin cavity 6. Thus, when the pin is inserted into the channel 4, the support member is installed in the pin cavity 6, so that the support member and the pin cavity 6 are engaged, thereby stably fixing the support member in the pin cavity 6. At this time, the pin can move axially within the channel 4 without bending or rotating.

[0033] A clamp 2 is provided in the channel 4. The clamp 2 is fixed on the connecting accessory 3. When the connecting accessory 3 is installed on the housing 1, the clamp 2 located on the connecting accessory 3 is in the channel 4.

[0034] The clamp 2 includes two circular rings 21 at both ends and multiple elastic pieces 22 disposed between the two circular rings 21. The multiple elastic pieces 22 are arranged around the center of the two circular rings 21. The elastic pieces 22 have an arc-shaped protrusion structure. The two ends of the elastic pieces 22 are fixedly installed on the opposite sides of the two circular rings 21. The middle part of the elastic piece 22 protrudes towards the line connecting the centers of the two circular rings 21. The middle parts of the multiple elastic pieces 22 all protrude towards the center of the circular rings 21, so that when the pin is inserted into the channel 4, the pin can pass through the two circular rings 21 along the center of the two circular rings 21. The protrusion of the middle part of the elastic piece 22 towards the center can then contact the pin.

[0035] Because the elastic sheet 22 is elastic, when the elastic sheet 22 is in continuous contact with the pin, the pin can maintain stable contact with the elastic sheet 22 no matter how the pin moves. When the pin is located in the middle of the ring structure composed of multiple elastic sheets 22, the volume of the pin will cause the elastic sheet 22 to deform. Under the compression of the pin, the middle part of the elastic sheet 22 will expand outward while the pin is in contact with it. Due to its own elasticity, the elastic sheet 22 will have a tendency to move towards the pin. Thus, when the pin moves, the elastic sheet 22 can maintain continuous contact with the pin.

[0036] A conductive plate 23 is provided on either side of the ring 21 at both ends of the clamp 2. The conductive plate 23 is used to fix the connection with the connecting accessory 3. After the conductive plate 23 is fixedly connected with the connecting accessory 3, it can provide a stable electrical connection, so that after the pin is inserted into the clamp 2, the electrical connection between the pin and the clamp 2 is stably connected to the connecting accessory 3.

[0037] The upper part of the connecting accessory 3 is a positioning key 31, which can form a stable mating structure with the external device. The positioning key 31 is preferably a joint structure for insertion. The bottom of the connecting accessory 3 is a mounting base 32, which has a mounting hole for mounting the clamp 2. The mounting base 32 also has a connecting groove, which forms a stable abutting fit with the conductive plate 23, so that the electrical connection between the clamp 2 and the pin is further conducted to the connecting accessory 3, and then to the external device through the connecting accessory 3. In other embodiments, the conductive plate 23 can be replaced with a protrusion on the ring 21, etc. The connection method between the mounting base 32 and the clamp 2 can also be selected by thread fixing or interference fit, etc., as long as the clamp can fully contact the mounting base 32 for electrical transmission and cannot move.

[0038] The mounting base 32 is installed in the opening inside the housing 1, and the mounting hole of the mounting base 32 overlaps with the center of the channel 4. Before the connecting accessory 3 is installed, the clamp 2 is pre-installed in the mounting hole, the conductive plate 23 on the clamp 2 is installed in the connecting groove, the connecting accessory 3 is installed in the opening of the housing 1, and the clamp 2 is concentrically set in the channel 4.

[0039] The end of the channel 4 that communicates with the pin cavity 6 is designed with an outward expansion structure to facilitate the insertion of the pin. The pin cavity 6 is provided with a connection hole on the side of the channel 4. A plug can be installed on the support to be inserted into the connection hole, so that the support is positioned inside the pin cavity 6 after the plug is engaged with the connection hole. Multiple protrusions can also be provided inside the pin cavity 6 to provide further support for the support.

[0040] The housing 1 has a needle port 7 at the end away from the needle cavity 6. The needle port 7 is an annular hollow structure protruding from the housing 1, which can guide and stabilize the needle, facilitate the precise movement of the needle end, and facilitate the needle to be further cooperated or connected with other devices.

[0041] When the elastic element of clamp 2 is engaged with the pin, since the elastic element is arranged around the pin, when the pin moves in the channel 4, multiple elastic elements maintain the structure with the pin in the circumferential direction. This ensures that when the pin and clamp 2 are engaged, the resistance of the pin remains relatively stable regardless of how the pin moves, and there will be no large fluctuations, thus affecting the use of external equipment.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
