The specific meaning of the above terms in the embodiments of the present invention can be understood by those skilled in the art according to specific situations.

In some embodiments of the present invention, as shown in fig. 1, an ophthalmic harness quick connector is provided, comprising a connector body 100 and a connection terminal 200, the connection terminal 200 comprising an elastic connector 210 and a contact terminal 220. A first end of the elastic connection member 210 extends into the connector body 100 and is connected to the connector body 100. A first end of the contact terminal 220 is connected to a second end of the elastic connection member 210, and a second end of the contact terminal 220 extends out of the connector body 100 and is used for electrical connection with an external temperature sensor.

Elastic connection piece 210 has the absorbing effect of buffering, can filter the slight vibration that receives the hand in-process and produce to it is more firm to make ophthalmology pencil high-speed connector be connected with the sensor, is difficult for droing.

In other embodiments of the present invention, as shown in fig. 1, the ophthalmic harness quick connector further comprises a magnetic member 110. The magnetic member 110 is disposed inside the connector body 100. The magnetic member 110 can attract the sensor, so that the connector and the sensor are more firmly connected. Simultaneously, the connector does not need to be connected with the sensor through terminal plugging, and the connector is convenient to mount and dismount by a user.

Specifically, in the present embodiment, the magnetic member 110 is specifically a common magnet, and those skilled in the art may also select an electromagnet as the magnetic member 110, and the presence or absence of the magnetism of the electromagnet may be controlled by switching on or off the electric switch. When the connector is required to be detached from the sensor, the electromagnet is only required to be powered off, the electromagnet losing magnetism is not adsorbed with the sensor, and the connector drops naturally.

In other embodiments of the present invention, as shown in fig. 1, the connector body 100 includes a housing 120 and a circuit board 130. The circuit board 130 is disposed inside the housing 120 and connected to a first end of the elastic connection member 210, and a second end of the contact terminal 220 extends to an outside of the housing 120. The magnetic member 110 is disposed inside the housing 120. When the contact terminal 220 is connected to the sensor, the contact terminal 220 is pressed by the surface of the sensor to compress the elastic member 212. When vibration is generated in the using process, the elastic connecting piece 210 has the function of buffering and absorbing the vibration due to the elasticity of the elastic connecting piece, so that the influence of the vibration on the contact terminal 220 can be reduced, and the contact terminal 220 is prevented from falling off from the sensor due to the vibration.

In other embodiments of the present invention, as shown in fig. 1 and 2, the elastic connection member 210 includes a base 211, an elastic member 212, and a protective shell 213. The first side of the base 211 is connected to the circuit board 130, and the second side is connected to the first end of the elastic member 212. A second end of the elastic member 212 is connected to the contact terminal 220. When the contact terminal 220 is connected to the sensor, the contact terminal 220 is pressed by the surface of the sensor to compress the elastic member 212. When vibration is generated in the using process, the elastic member 212 has the effect of buffering and absorbing vibration due to elasticity, so that the influence of the vibration on the contact terminal 220 can be reduced, and the contact terminal 220 is prevented from falling off from the sensor due to the vibration.

In other embodiments of the present invention, as shown in fig. 2, the elastic member 212 is a linear compression spring. The linear compression spring is a compression spring bearing an axial force, and the deformation generated when the linear compression spring is compressed is linear, so that the contact terminal 220 can be vertically contacted with the sensor when the linear compression spring is bent, and the condition of poor contact is avoided.

Specifically, in the present embodiment, a first end of the elastic connecting element 210 is fixedly connected to the circuit board 130. The end of the contact terminal 220 that protrudes outside the housing 120 is used for connection to a sensor.

In other embodiments of the present invention, as shown in fig. 1, the housing 120 includes a first casing 121 and a second casing 122 connected to each other. The circuit board 130 is connected to one side of the second housing 122. The second end of the contact terminal 220 extends to the outside of the second housing 122. The outer surface of the second housing 122 is provided with a first stopper plate 1221 and a second stopper plate 1222. In the present embodiment, the first casing 121 and the second casing 122 connected to each other jointly enclose a hollow housing 120.

Specifically, in this embodiment, the first limiting plate 1221 and the second limiting plate 1222 are both arc-shaped, and the shape of the first limiting plate and the second limiting plate 1222 is similar to the contour of the eye, so as to limit the connector by using the contour of the eye, prevent the connector from slipping, and enable the connector and the sensor to be firmly connected.

In other embodiments of the present invention, as shown in fig. 3, the outer surface of the second housing 122 is further provided with a lifting groove 123. Specifically, in the present embodiment, the lifting groove 123 can accommodate the size of one finger. When the connector needs to be removed, the user only needs to put fingers into the lifting groove 123 to pull up the connector. The pull-up slots 123 provide a point for a user to apply force to the connector to more easily remove the connector.

In other embodiments of the present invention, as shown in fig. 3, the lifting groove 123 is provided with a chamfer 1231. The chamfer 1231 protects the user's fingers from being scratched by sharp corners when the connector is removed.

In other embodiments of the present invention, as shown in fig. 1, the housing 120 further comprises a wire guide drum 124. The wire barrel 124 can protect the wires and manage the wire harnesses in a centralized manner, so that the wire harnesses are prevented from being wound.

In other embodiments of the present invention, as shown in fig. 1 and 3, the number of the connection terminals 200 is several. Specifically, the greater the number of the connection terminals 200, the more stable the data transmission between the connector and the sensor. The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
