Description

Technical Field

[0001] The invention relates to the field of medical devices, in particular to a snap-on sensor seat. Background Art

[0002] The Chinese invention patent (publication number CN114305360A, patent name is Intelligent driving device for blood pressure or hemodynamic detection sensor), which has the following description in the specification: "The slider assembly is provided with a sensor seat for accommodating the sensor," and "The connecting rod assembly is hinged to the sensor seat for accommodating the sensor", which shows that the sensor seat is used to hold the sensor and it is also movable. Since the sensor seat is connected to the sensor through the contacts of the gold finger, and the sensor needs to be replaced frequently, the connection between the sensor seat and the sensor needs to be relatively stable.

[0003] Furthermore, since the sensor needs to be replaced frequently, the contacts on the sensor often rub against the gold fingers on the cable. In order to ensure good contact, the cable also needs to be replaced after a period of use. The existing card holder is generally inconvenient to fix the cable, and it is even more inconvenient to replace the cable. For this reason, we propose a snap-on sensor holder to solve the above technical problems. Summary of the invention

[0004] The object of the present invention is to overcome the disadvantages of the prior art and provide a snap-fit ​​sensor seat.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A snap-on sensor seat comprises a hard shell and a cable assembly. The hard shell comprises a fixed lower shell and a movable upper shell clamped in the fixed lower shell. A cable hole is provided on the movable upper shell, and one end of the cable assembly is located in the cable hole.

[0007] A further technical solution is that the movable upper shell includes an upper baffle and an upper slot shell with a groove, and the upper baffle and the upper slot shell are connected, the wiring hole is opened on the upper slot shell, and the upper slot shell is also provided with two symmetrical slots.

[0008] A further technical solution is that the fixed lower shell includes a lower baffle and a lower tank shell, and the lower baffle is connected to the lower tank shell.

[0009] A further technical solution is that a pin and a buckle are fixedly provided on the bottom surface of the upper baffle, and a socket corresponding to the pin and a buckle hole corresponding to the buckle are opened on the lower baffle.

[0010] A further technical solution is that a buckle hole is provided on the upper tank shell, and a buckle matched with the buckle hole is provided on the inner wall of the lower tank shell.

[0011] A further technical solution is that the cable assembly includes a cable and a gold finger circuit board fixed to the end of the cable, and the gold finger circuit board is located between the cable hole and the inner wall of the lower slot shell.

[0012] A further technical solution is that a through hole is also opened on the lower tank shell, and the other end of the cable passes through the through hole and extends to the outside of the hard shell.

[0013] A further technical solution is that the buckle hole is opposite to the cable hole.

[0014] A further technical solution is that a limiting column and an arc-shaped limiting arc plate are fixedly provided on the upper baffle.

[0015] A further technical solution is that an ear plate is fixedly provided on the fixed lower shell, and a fixing hole is opened on the ear plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention can achieve the purpose of quickly separating the movable upper shell and the fixed lower shell by separating the sensor housing into a movable upper shell and a fixed lower shell, and realize snap connection between them, so as to facilitate the replacement of the cable assembly placed therebetween. Moreover, since the cable has a certain width, the cable can be pressed between the movable upper shell and the fixed lower shell when they are snapped together. In this way, the gold finger circuit board and the cable are fixed to achieve the purpose of stable transmission of electrical signals, and the cable assembly can be easily replaced at the same time.

[0018] 2. The present invention configures the cable assembly to be a hard gold finger circuit board and a thin film cable, so that the gold finger circuit board can be easily fixed, and the thin film cable can be easily pressed between the two shells, thereby ensuring the stability of the cable assembly in the hard shell.

[0019] 3. The present invention provides card slots at both ends of the upper slot shell, and cooperates with the card slots and the limit arc plate to effectively snap-fit ​​the sensor, thereby making it more stable and avoiding poor contact between the sensor contacts and the gold fingers on the gold finger circuit board when the device is in motion.

[0031] Example:

[0032] Please refer to Figure 1 The embodiment shown in FIG. 4 is a snap-on sensor seat, comprising a hard shell 1 and a cable assembly 2. The hard shell 1 is used to hold the sensor, and the cable assembly 2 is used to exchange and transmit the data collected by the sensor.

[0033] The hard shell 1 includes a fixed lower shell 12 and a movable upper shell 11 clamped in the fixed lower shell 12, the movable upper shell 11 includes an annular upper baffle 111 and an upper slot shell 112 with a groove, and the upper baffle 111 and the upper slot shell 112 are connected, the groove in the upper slot shell 112 is used to hold the sensor, the fixed lower shell 12 includes a lower baffle 121 corresponding to the upper baffle 111 and a lower slot shell 122 corresponding to the upper slot shell 112, and the lower baffle 121 is connected to the lower slot shell 122.

[0034] The upper slot shell 112 is rectangular in shape, and is provided with a card slot 118 at both ends along its long axis direction. The card slot 118 corresponds to the buckles at both ends of the sensor, that is, when the sensor is inserted into the groove in the movable upper shell 11, the buckles at both ends will be snapped into the card slot 118, thereby achieving the purpose of fixing the sensor.

[0035] The movable upper shell 11 is provided with a cable hole 113, which is provided on the upper slot shell 112, and one end of the cable assembly 2 is located in the cable hole 113, and the buckle hole 116 is opposite to the cable hole 113.

[0036] A pin 117 and a buckle 114 are fixed to the bottom surface of the upper baffle 111, and a socket 124 corresponding to the pin 117 and a buckle hole 125 corresponding to the buckle 114 are provided on the lower baffle 121. There are multiple pins 117, which are evenly distributed on the bottom surface of the upper baffle 111. A buckle hole 116 is also provided on the upper slot shell 112, and a buckle 123 matched with the buckle hole 116 is provided on the inner wall of the lower slot shell 122.

[0037] When the movable upper shell 11 is snapped into the fixed lower shell 12, the pin 117 is inserted into the corresponding hole 124, the buckle 114 is inserted into the buckle hole 125 and snapped, and the buckle 123 is snapped into the buckle hole 116. The multiple pins 117 are used to position the movable upper shell 11 to prevent it from rotating or moving. Furthermore, the two buckles 114 are respectively located above the cable hole 113 and the buckle hole 125, that is, at this time the movable upper shell 11 is completely snapped into the fixed lower shell 12.

[0038] The cable assembly 2 includes a flexible cable 21 and a gold finger circuit board 22 fixed to the end of the cable 21. The gold finger circuit board 22, that is, a hard circuit board, is provided with a gold finger, and the gold finger is connected to the cable 21. When the cable assembly is packaged, the flexible cable 21 is pressed between the movable upper shell 11 and the fixed lower shell 12, and the gold finger circuit board 22 is located between the cable hole 113 and the inner wall of the lower slot shell 122. Since the length and width of the gold finger circuit board 22 are greater than the length and width of the cable hole 113, the gold finger circuit board 22 is squeezed and its gold finger can be exposed from the cable hole 113. When the output terminal of the sensor is elastic, the elastic force will force its output terminal to contact with the gold finger, that is, the circuit is connected. A through hole is also opened on the lower slot shell 122, and the other end of the cable 21 passes through the through hole and extends to the outside of the hard shell 1, that is, the other end of the cable extends out and is connected to the control end.

[0039] A limiting column 115 and an arc-shaped limiting arc plate 114 are fixed on the upper baffle 111, and an ear plate is fixed on the fixed lower shell 12, and a fixing hole is opened on the ear plate. The two limiting columns 115 are used to correspond to the opening position of the pull ring on the sensor, which is used to assist in fixing the pull ring and the sensor, and the limiting arc plate 114 is used to surround the sensor and the pull ring to prevent them from shaking.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
