[0030] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] The utility model provides a connector positioning device, which is used to position the connector. Figure 1 The overall structure of the connector is shown, combined with Figure 1It can be seen that the housing of the connector is convex with protrusions, and the housing of the connector is also provided with a recess. Specifically, the protrusion of the connector is mainly the illustrated structure A Luer connector, and the Luer connector A is used for water injection. Another protrusion is structure B, and structure B is used for buckling with an external device. And structure C is another buckle position for assembling with other parts of the connector, but the buckle position of structure C is a concave structure. The solution of the present application provides a device capable of positioning the connector.

[0034] In one embodiment, please refer to Figures 2 to 5 , the positioning device for the connector includes a first housing 1 and a second housing 2. The first housing 1 and the second housing 2 are detachably connected, and the connection between the first housing 1 and the second housing 2 constitutes the overall structure of the positioning device for the connector. When the first housing 1 and the second housing 2 are connected together, a limiting groove 3 adapted to the outer dimension of the connector is formed therebetween. When the connector is located in the limiting groove 3, the groove wall of the limiting groove 3 fits against the outer surface of the connector, and the movement of the connector in the first direction and the second direction can be restricted.

[0035] A relief groove 13 adapted to the protrusion is provided at the position corresponding to the protrusion on the first housing 1 and / or the second housing 2, and the relief groove 13 communicates with the limiting groove 3. In this way, when the connector is adapted to the limiting groove 3, the protrusion can be inserted and adapted to the relief groove 13. It should be noted that the number and position of the relief grooves 13 need to be determined according to the number and position of the protrusions on the surface of the connector. For example, as described above, the connector has two protrusions, so in this embodiment, the corresponding number of relief grooves 13 are also provided at the corresponding positions on the first housing 1 and / or the second housing 2.

[0036] A limiting protrusion 14 is further protruded at the position corresponding to the recess on the first housing 1 and / or the second housing 2. The limiting protrusion 14 is located in the limiting groove 3 and is adapted to the recess, so that the limiting protrusion 14 can be inserted and adapted to the recess of the connector.

[0037] The cooperation between the relief groove 13 and the protrusion, and the cooperation between the limiting protrusion 14 and the recess can restrict the movement of the connection in the third direction in the limiting groove 3. Among them, the first direction, the second direction, and the third direction are perpendicular to each other. It is worth mentioning that, please combine Figure 2 and Figure 3 , the first direction is parallel to the direction shown by the X-axis in Figure 3 , the second direction is parallel to the Z-axis direction in Figure 2 or Figure 3 , and the third direction is parallel to the Y-axis direction in Figure 2 .

[0038] The direction in which the limiting groove 3 is opened is parallel to the third direction. It can be predicted that when the connector is located in the limiting groove 3, the position of the connector on the plane where the first direction and the second direction are located is limited. If there is no protruding structure on the surface of the connector, and the outer surface of the connector fits on the groove wall of the limiting groove 3, then the connector can only move along the third direction. However, the outer surface of the connector is not only provided with protrusions, but also with recessed parts. In this way, when the connector is placed in the limiting groove 3, the protrusion on the outer surface of the connector can be plugged and adapted into the giving groove 13, and the limiting protrusion 14 can be plugged and adapted into the recessed part. This plug-in fit can limit the movement of the connector in the third direction, thereby fixing the connector located in the limiting groove 3 in the first direction, the second direction and the third direction.

[0039] By setting the first shell 1 and the second shell 2, a limiting groove 3 is formed between the first shell 1 and the second shell 2, and the connector can be plugged into the limiting groove 3, and the limiting groove 3 can limit the movement of the connector in the first direction and the second direction. The protrusion on the connector located in the limiting groove 3 can also be plugged into the clearance groove 13, and the limiting protrusion 14 can also be plugged into the recessed part of the connector. Through the cooperation between the protrusion and the clearance groove 13, and the cooperation between the limiting protrusion 14 and the recessed part, the movement of the connector in the third direction can be limited. Therefore, the connector positioning device of the present application can set a matching limiting groove 3 according to the shape of the connector, and set the clearance groove 13 and the limiting protrusion 14 correspondingly according to the structural layout of the outer surface of the connector, so that the position of the connector located in the limiting groove 3 can be fixed. The structure of the entire connector positioning device is simple, and the position of the connector can be effectively fixed, so that its position is not easy to be offset, thereby facilitating the subsequent assembly of the connector with other components and improving the assembly efficiency.

[0040] In one embodiment, see Figures 2 to 5 The limiting groove 3 is formed by the first shell 1 and the second shell 2. Specifically, the first shell 1 is provided with a first half groove 31, and the second shell 2 is provided with a second half groove 32. When the first shell 1 and the second shell 2 are connected, the first half groove 31 and the second half groove 32 are surrounded to form the limiting groove 3.

[0041] In one embodiment, there is a mounting end surface between the first shell 1 and the second shell 2, a plurality of positioning members 15 are protruding from the first shell 1, and a positioning groove 22 that is plugged in and adapted to the positioning members 15 is opened on the second shell 2. The plug-in fit between the positioning members 15 and the positioning groove 22 can limit the relative movement of the first shell 1 and the second shell 2 within the mounting end surface.

[0042] Please combine Figure 4, the mounting end face can be parallel to the plane formed between the X-axis and the Y-axis. That is to say, the cooperation between the positioning member 15 and the positioning groove 22 can limit the relative movement of the first housing 1 and the second housing 2 in the first direction and the third direction.

[0043] Specifically, both the first housing 1 and the second housing 2 have mounting end faces. When installing the two housings, the mounting end faces of the two housings are aligned and fitted. In this embodiment, the mounting end faces of the first housing 1 and the second housing 2 are rectangularly arranged. The positioning members 15 are arranged at the four corners of the first housing 1, and the corresponding positioning grooves 22 are opened at the four corners of the second housing 2.

[0044] A connecting member 5 is also movably connected between the first housing 1 and the second housing 2. The connecting member 5 has a locking position for restricting the movement of the first housing 1 and the second housing 2 in the direction perpendicular to the mounting end face, and an unlocking position for unlocking the first housing 1 and the second housing 2.

[0045] It should be noted that the direction perpendicular to the mounting end face is also the direction parallel to the second direction. When the connecting member 5 is in the locking position, it can restrict the relative movement of the first housing 1 and the second housing 2 in the second direction. In this way, combined with the plug-in connection between the positioning member 15 and the positioning groove 22, the fixed connection of the first housing 1 and the second housing 2 can be realized.

[0046] In a specific embodiment, both the first housing 1 and the second housing 2 are provided with moving grooves 40. The moving grooves 40 are opened along the second direction. When the positioning member 15 and the positioning groove 22 are plugged and adapted, the moving grooves 40 on the first housing 1 and the moving grooves 40 on the second housing 2 are arranged opposite to each other.

[0047] The first housing 1 has a first limiting platform 11 protruding into the moving groove 40, and the second housing 2 has a second limiting platform 21 protruding into the moving groove 40. The first limiting platform 11 and the second limiting platform 21 are arranged along the direction perpendicular to the mounting end face (i.e., the second direction). The connecting member 5 includes a connecting body 51 inserted into the moving groove 40, and a first limiting portion 52 and a second limiting portion 53 provided at both ends of the connecting body 51.

[0048] The dimension of the moving groove 40 in the first direction is the width of the moving groove 40. The width of the moving groove 40 is greater than or equal to the dimensions of the first limiting portion 52 and the second limiting portion 53 in the first direction. The first limiting platform 11 and the second limiting platform 21 reduce the width of the moving groove 40 to be less than the dimensions of the first limiting portion 52 and the second limiting portion 53 in the first direction. When the connecting member 5 is in the locking position, the first limiting platform 11 and the second limiting platform 21 are clamped between the first limiting portion 52 and the second limiting portion 53.

[0049] It is worth mentioning that the movable slot 40 has a predetermined length in the third direction, the locking position and the unlocking position are spaced apart on the path of the movable slot 40 in the third direction, and the connecting body 51 of the connecting member 5 can move in the movable slot 40 along the third direction so as to change between the locking position and the unlocking position.

[0050] In a specific embodiment, the first housing 1 is further provided with a mounting slot 16 communicating with the movable slot 40. An installation member 7 is installed in the mounting slot 16. The first limiting portion 52 is located in the mounting slot 16, and one end of the first limiting portion 52 close to the second housing 2 can abut against the bottom wall of the mounting slot 16. When the installation member 7 is installed in the mounting slot 16, the end portion of the installation member 7 abuts against the end of the first limiting portion 52 facing away from the second housing 2, so that the first limiting portion 52 can move along the path of the mounting slot 16 between the installation member 7 and the bottom of the mounting slot 16.

[0051] It should be noted that the installation member 7 is convexly provided with a buckling block 71, and the first housing 1 is provided with a buckling groove 17 communicating with the mounting slot 16. The buckling groove 17 is opened on the side wall of the mounting slot 16. The buckling block 71 can be inserted and adapted to the buckling groove 17. Through the insertion and cooperation of the buckling block 71 and the buckling groove 17, the installation member 7 can be buckled on the first housing 1.

[0052] In a specific embodiment, the first limiting portion 52 is further connected with a guiding member 6. When the connecting body 51 is inserted into the movable slot 40, the guiding member 6 extends along the moving direction of the connecting body 51, and the guiding member 6 can penetrate through the first housing 1. By providing the guiding member 6 and passing the guiding member 6 through the first housing 1, when the connecting body 51 moves, the guiding member 6 can play a guiding role, so that the connecting body 51 is not likely to shake or deviate.

[0053] More specifically, an elastic member 61 is sleeved on the guiding member 6. Two ends of the elastic member 61 respectively abut against the first housing 1 and the first limiting portion 52. In the free state, the elastic member 61 can force the connecting member 5 to move to the locking position. The guiding member 6 and the elastic member 61 are both located in the mounting slot 16.

[0054] When it is necessary to unlock the first housing 1 and the second housing 2, an external force is applied to move the connecting body 51 from the locking position to the unlocking position. The elastic member 61 is located on the path where the first limiting portion 52 follows the connecting body 51 to move. During the process of the connecting body 51 moving towards the unlocking position, the first limiting portion 52 squeezes the elastic member 61 to generate an elastic force of the elastic member 61. When the external force is removed, the elastic force of the elastic member 61 forces the first limiting portion 52 to return to its original position, and then drives the connecting body 51 to return to its original position.

[0055] It should be noted that in this embodiment, the elastic member 61 is preferably a spring.

[0056] In a specific embodiment, a placement platform 18 is further provided on the first shell 1, and the placement platform 18 is provided in the installation groove 16. The placement platform 18 is provided with a first placement groove 181 and a second placement groove 182 which are connected and arranged, wherein the first placement groove 181 is relatively close to the first limiting portion 52, and the first placement groove 181 and the second placement groove 182 are opened along the third direction. The dimension of the first placement groove 181 in the direction perpendicular to the opening path thereof is greater than the dimension of the second placement groove 182 in the direction perpendicular to the opening path thereof, so that the connection between the first placement groove 181 and the second placement groove 182 forms a step structure.

[0057] One end of the guide member 6 away from the first limiting portion 52 is located in the first placement groove 181 and the second placement groove 182 , and one end of the elastic member 61 away from the first limiting portion 52 is inserted into the first placement groove 181 and abuts against the step structure.

[0058] In one embodiment, see Figures 2 to 5 , the movable groove 40 is arranged to penetrate the first shell 1 along the second direction, and the end of the connecting member 5 away from the second shell 2 extends out of the movable groove 40 and protrudes from the first shell 1 to form a toggle end 511, and the entire connecting member 5 can be driven to move by toggling the toggle end 511. A plurality of supporting members 12 are protruded from the end of the first shell 1 facing away from the second shell 2, and the size of the supporting member 12 protruding from the first shell 1 is greater than or equal to the size of the toggle end 511 of the connecting member 5 protruding from the first shell 1, that is, the distance between the end of the supporting member 12 away from the first shell 1 and the first shell 1 is greater than or equal to the distance between the end face of the toggle end 511 away from the second shell 2 and the first shell 1. In one case, the first shell 1 needs to be placed facing the placement surface, that is, at this time, the toggle end 511 is located at the bottom, and the toggle end 511 protrudes from the first shell 1. By providing the supporting member 12, the first shell 1 can be supported, so that there is a gap between the placement surface and the first shell 1, so that the toggle end 511 is located in the gap.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
