Description

TECHNICAL FIELD

[0001] The present application relates to the field of blood glucose detection equipment, and in particular to a connecting device of a blood glucose detector. BACKGROUND

[0002] The blood glucose detection equipment is an electronic instrument for detecting the content of blood glucose in blood. When in use, the collected blood is dropped on a blood glucose test paper, and then the blood glucose test paper is inserted into the blood glucose detection equipment, so that the conductive electrode of the blood glucose test paper is electrically connected with the connecting device of the blood glucose detector, and the conductive electrode transmits the information on the blood glucose test paper to the blood glucose detection equipment in the form of a data signal.

[0003] The connecting device of the existing multifunctional blood glucose detector is assembled by a base, a group of contact terminals arranged side by side, and side pushing mechanisms arranged on both sides of the base. The contact terminals are used for data connection with the blood glucose test paper. However, the group of contact terminals is prone to deformation during the insertion and removal of the blood glucose test paper, and is prone to unstable connection in the long-term use, thereby affecting the use. In addition, the group of contact terminals is used for electrical connection with a group of conductive electrodes on the blood glucose test paper. If one of the contact terminals cannot be connected with the corresponding conductive electrode on the blood glucose test paper, the data information cannot be transmitted, and the service life of the connecting device of the multifunctional blood glucose detector is affected.

[0004] Meanwhile, the side pushing mechanisms in the connecting device of the existing multifunctional blood glucose detector are arranged on both sides of the base, so that the space occupied by the two groups of side pushing mechanisms is large, and the volume of the connecting device of the multifunctional blood glucose detector needs to be increased accordingly.

[0005] In order to ensure the stability of the connection, some connecting devices of multifunctional blood glucose detectors use two or more groups of contact terminals arranged symmetrically in the base, which are arranged in two layers. The blood glucose test paper needs to be inserted between the two layers of contact terminals for data connection. However, this arrangement further increases the thickness of the base. In order to arrange the two layers of contact terminals, the overall volume of the base also needs to be increased accordingly, so that the overall volume is very large and is not convenient to use.

[0051] The embodiments of the present application will be described below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments.

[0052] It should be noted that when one component is considered to be "connected" to another component, it can be directly connected to the other component or can exist simultaneously with a middle component. When one component is considered to be "provided on" another component, it can be directly provided on the other component or can exist simultaneously with a middle component. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and the like used herein are for illustrative purposes only.

[0053] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0054] The embodiments of the present application provide a connecting device 100 of a blood glucose meter, comprising:

[0055] A base 110 is provided with a receiving groove 110a, and the receiving groove 110a has a first position 110b and a second position 110c;

[0056] A group of first contact terminals 120 are located in the receiving groove 110a and extend to the first position 110b;

[0057] A group of second contact terminals 130 are located in the receiving groove 110a and extend to the second position 110c, and one first contact terminal 120 is provided between two adjacent second contact terminals 130, and the first contact terminal 120 is arranged in parallel with the second contact terminal 130;

[0058] Wherein, the blood glucose test paper 170 is placed in the receiving groove 110a, and the blood glucose test paper 170 performs data transmission with the first contact terminal 120 and / or the second contact terminal 130.

[0059] Please refer to Figures 1-10 In this embodiment, the first contact terminal 120 is arranged between two adjacent second contact terminals 130, and is arranged in parallel in a spaced manner, so that the first contact terminal 120 and the second contact terminal 130 can both perform data transmission with the blood glucose test paper 170.

[0060] At the same time, the first contact terminal 120 and the second contact terminal 130 are arranged in the same plane in a front-to-back parallel and spaced manner, so that the overall volume of the connecting device 100 of the blood glucose meter is smaller.

[0061] The first contact terminals 120 and the second contact terminals 130 are arranged in the housing groove 110a in parallel, and the first contact terminals 120 extend to the first position 110b and the second contact terminals 130 extend to the second position 110c, so that the first contact terminals 120 or the second contact terminals 130 can transmit data with the blood glucose test paper 170. If the first contact terminals 120 are damaged, the second contact terminals 130 can still transmit data with the blood glucose test paper 170. If the second contact terminals 130 are damaged, the first contact terminals 120 can still transmit data with the blood glucose test paper 170, so that the problem that the connection device 100 of the blood glucose meter cannot be used due to single point failure is avoided.

[0062] It should be noted that the base 110 is generally a rectangular base 110, the housing groove 110a is generally a rectangular through groove, and the housing groove 110a is completely through the base 110 along one side. The first position 110b and the second position 110c are two positions in the housing groove 110a, and the first position 110b and the second position 110c are arranged in parallel. The line between the first position 110b and the second position 110c is arranged along the direction in which the housing groove 110a is formed.

[0063] The first contact terminals 120 extend to the first position 110b and are electrically connected to the first conductive electrode 171 of the blood glucose test paper 170, so that the blood glucose test paper 170 is electrically connected to the first contact terminals 120 through the first conductive electrode 171. The second contact terminals 130 extend to the second position 110c and are electrically connected to the second conductive electrode 172 of the blood glucose test paper 170, so that the blood glucose test paper 170 is electrically connected to the second contact terminals 130 through the second conductive electrode 172. The data information on the blood glucose test paper 170 can be electrically connected to the first contact terminals 120 through the first conductive electrode 171 or electrically connected to the second contact terminals 130 through the second conductive electrode 172, so that the data information on the blood glucose test paper 170 is transmitted to the connection device 100 of the blood glucose meter. The first contact terminals 120 are generally "√" shaped metal springs or signal transmission terminals, and the second contact terminals 130 are generally "√" shaped metal springs.

[0064] In other embodiments, the first contact terminals 120 and the second contact terminals 130 can be electrically connected to the blood glucose test paper 170 to form a data transmission channel for data transmission.

[0065] In other embodiments, a plurality of first contact terminals 120 and second contact terminals 130 can be arranged in front of and behind each other.

[0066] In at least one embodiment of the present application, the first position 110b and the second position 110c are arranged in parallel, and the line connecting the first position 110b and the second position 110c is perpendicular to the opening direction of the accommodation groove 110a.

[0067] Please refer to Figures 1-10 In the present embodiment, the first position 110b and the second position 110c are arranged in parallel, and the line connecting the first position 110b and the second position 110c is perpendicular to the opening direction of the accommodation groove 110a, so that the first contact terminal 120 and the second contact terminal 130 are arranged in front and back along the opening direction of the accommodation groove 110a, thereby reducing the space for arranging the first contact terminal 120 and the second contact terminal 130, so that the space of the base 110 can be smaller, and thus the volume of the connection device 100 of the blood glucose meter can be smaller.

[0068] Secondly, by arranging a group of first contact terminals 120 and a group of second contact terminals 130 in front and back, after the blood glucose test paper 170 is inserted into the accommodation groove 110a, the first contact terminal 120 and the second contact terminal 130 are respectively electrically connected with the first conductive electrode 171 and the second conductive electrode 172, thereby ensuring that the electrical connection at two places can form a data transmission channel between the connection device 100 of the blood glucose meter and the blood glucose test paper 170, so as to transmit the data of the blood glucose test paper 170 to the connection device 100 of the blood glucose meter.

[0069] In at least one embodiment of the present application, the base 110 is provided with a mounting surface 110d, and the first contact terminal 120 has a first connecting end 121 away from the mounting surface 110d, and the first connecting end 121 is located at the first position 110b, and in the opening direction of the accommodation groove 110a, the distance from the first connecting end 121 to the mounting surface 110d is denoted as a.

[0070] The second contact terminal 130 has a second connecting end 131 away from the mounting surface 110d, and the second connecting end 131 is located at the second position 110c, and in the opening direction of the accommodation groove 110a, the distance from the second connecting end 131 to the mounting surface 110d is denoted as b, and the relationship a>b is satisfied.

[0071] Please refer to Figures 1-10 In the present embodiment, in the opening direction of the accommodation groove 110a, the distance from the first connecting end 121 to the mounting surface 110d is greater than the distance from the second connecting end 131 to the mounting surface 110d, so that the first contact terminal 120 and the second contact terminal 130 are arranged in front and back, thereby reducing the space layout in the base 110, so that the layout of the first contact terminal 120 and the second contact terminal 130 is more reasonable, and the internal space of the base 110 is saved.

[0072] The blood glucose test paper 170 is fixed in the accommodation groove 110a by the point clamping of the first contact terminal 120 and the second contact terminal 130, so that the connection of the blood glucose test paper 170 and the connecting device 100 of the blood glucose detector is more stable.

[0073] The first contact terminal 120 and the second contact terminal 130 are made of high-toughness phosphor bronze material, so that the first contact terminal 120 and the second contact terminal 130 can meet the deformation-free multiple plugging to increase the service life of the connecting device 100 of the blood glucose detector.

[0074] Secondly, the base 110 is assembled with the first contact terminal 120 and the second contact terminal 130, so that the assembly is simpler and more efficient.

[0075] The first contact terminal 120 and the second contact terminal 130 are fixed through the mounting surface 110d, one end of the first contact terminal 120 away from the first connecting end 121 penetrates the mounting surface 110d and is fixed and electrically connected with the circuit board 150, and one end of the second contact terminal 130 away from the second connecting end 131 penetrates the mounting surface 110d and is fixed and electrically connected with the circuit board 150.

[0076] The mounting surface 110d is perpendicular to the opening direction of the accommodation groove 110a and is a plane.

[0077] In at least one embodiment of the present application, the connecting device 100 of the blood glucose detector further comprises:

[0078] The pushing block 140 is accommodated in the accommodation groove 110a at one end and extends to the outside through the base 110 at the other end, and the pushing block 140 is in sliding connection with the base 110.

[0079] Please refer to Figures 1-10 In the present embodiment, after the blood glucose test paper 170 is inserted into the accommodation groove 110a for data transmission, the pushing block 140 is pushed to move the pushing block 140 along the opening direction of the accommodation groove 110a, and the pushing block 140 pushes the blood glucose test paper 170, so that the blood glucose test paper 170 is pushed out of the accommodation groove 110a, facilitating the data transmission of the subsequent blood glucose test paper 170 next time.

[0080] In at least one embodiment of the present application, the base 110 is provided with a sliding groove 110e in communication with the accommodation groove 110a, and one end of the pushing block 140 is accommodated in the accommodation groove 110a and the other end extends to the outside of the base 110 through the accommodation groove 110a and the sliding groove 110e.

[0081] Please refer to Figures 1-10In the embodiment, after the data transmission of the blood glucose test paper 170 in the base 110 is completed, the pushing block 140 is pushed in the direction away from the mounting surface 110d along the opening direction of the accommodation groove 110a, so that the pushing block 140 pushes the blood glucose test paper 170 in the sliding groove 110e, and the blood glucose test paper 170 is pushed out of the accommodation groove 110a, so as to facilitate the next data transmission.

[0082] It should be noted that the opening direction of the sliding groove 110e is perpendicular to the opening direction of the accommodation groove 110a, and the sliding groove 110e is a rectangular through groove.

[0083] After the blood glucose test paper 170 is pushed out of the accommodation groove 110a, the pushing block 140 is moved in the direction close to the mounting surface 110d, so that the pushing block 140 moves to the original position, so that the pushing block 140 can push the blood glucose test paper 170 out of the accommodation groove 110a after the next data transmission is completed.

[0084] In at least one embodiment of the application, the pushing block 140 comprises:

[0085] Two pushing parts 141 are located in the accommodation groove 110a, and a group of second contact terminals 130 are arranged between the two pushing parts 141.

[0088] Please refer to Figures 1-10 In the embodiment, since the group of second contact terminals 120 is located between the two pushing parts 141, the two pushing parts 141 avoid excessive deformation of the pushing block 140 to the first contact terminal 120 or the second contact terminal 130 during the pushing of the blood glucose test paper 170, so as not to damage the first contact terminal 120 and the second contact terminal 130.

[0089] During the pushing of the blood glucose test paper 170, the through part 143 is pushed, and the sliding block 142 is driven to slide in the accommodation groove 110a, so that the two pushing parts 141 push the two ends on the same side of the blood glucose test paper 170, so as to ensure that the pushing parts 141 have uniform force on the blood glucose test paper 170, so that the blood glucose test paper 170 can be smoothly pushed out of the accommodation groove 110a, and the blood glucose test paper 170 is not stuck due to uneven application of force.

[0090] It should be noted that the penetrating portion 143 is substantially columnar. The sliding block 142 is substantially plate-shaped, and the length direction of the sliding block 142 is perpendicular to the length direction of the penetrating portion 143. The pushing portion 141 is substantially plate-shaped, and the length direction of the pushing portion 141 is arranged along the length direction of the penetrating portion 143.

[0095] The communication groove 150a is substantially a penetrating groove, and the opening direction of the communication groove 150a is arranged along the opening direction of the sliding groove 110e.
