Description

Technical Field

[0001] The utility model relates to the technical field of sensor installation, in particular to a sensor connector. Background Art

[0002] A sensor is a detection device that can sense the information to be measured and transform the sensed information into an electrical signal or other required form of information output according to a certain rule to meet the requirements of information transmission, processing, storage, display, recording, and control. The existence and development of sensors endow objects with senses such as touch, taste, and smell, making objects come alive. Sensors are the extension of human five senses and have the characteristics of miniaturization, digitization, intelligence, multi-functionality, systematization, and networking. It is the primary link to achieve automatic detection and automatic control.

[0003] Most existing sensors are installed by screwing or bolt fixing to install the sensor with the fixed connector at the required installation position. For screw connection, during long-term use, the threads will rust, which easily increases the risk of sensor detachment. And most sensors are relatively small in size. For bolt fixing, when the bolt size is too small and the installation object has a high vibration frequency, the bolt will also fall off due to vibration, resulting in a decrease in the fixing stability after the sensor is installed. It is necessary to design a sensor connector to solve the above-mentioned problems. Summary of the Utility Model

[0004] The purpose of the utility model is to propose a sensor connector to solve the deficiencies existing in the prior art.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A sensor connector includes a sensor, a fixed connector, and a fixing device. A plurality of contact terminals are equidistantly arranged on the right side of the sensor, and a plurality of sliders are equidistantly arranged on the outer wall of the right side of the sensor. A plurality of terminal jacks are equidistantly arranged inside the left side of the fixed connector, and a plurality of chutes are equidistantly arranged on the inner wall of the left side of the fixed connector. Insertion plates are fixedly connected to both the upper and lower ends of the right side of the sensor, and fixing devices are arranged at both the upper and lower ends of the left side of the fixed connector; the sliders are respectively slidably connected to the inner sides of the corresponding chutes, the contact terminals are respectively inserted and connected to the inner sides of the corresponding terminal jacks, and the insertion plates and the fixing device are used to connect and fix the sensor and the fixed connector;

[0007] Through the above technical solution, first insert the right end of the sensor side into the left end of the fixed joint, so that the sliders are slidably connected to the inner sides of the corresponding slide grooves, and the contact terminals are inserted and connected to the inner sides of the corresponding terminal sockets. When the sensor is inserted, the upper and lower insertion plates are locked and fixed by the fixing devices respectively, and the sensor and the fixed joint are connected and fixed and locked to prevent them from falling off.

[0008] Further, the fixing device comprises an insertion block, an extension column is arranged at the outer end of the insertion block, a clamping column is slidably connected to the inner side of the extension column, a spring is arranged at the outer part of the clamping column, and the outer end of the clamping column is rotatably connected to the pressing block through a connecting rod;

[0009] Through the above technical solution, the sensor can be fixed to the fixed joint to prevent the sensor from falling off, and the sensor can be quickly installed and removed, avoiding the risk of the sensor falling off due to loose screws for a long time in the traditional way of fixing with screws.

[0010] Furthermore, a slot is provided on the left side of each of the insertion blocks;

[0011] The above technical solution facilitates locking between the insertion plate and the locking column.

[0012] Furthermore, a locking hole is provided in the middle of the left side of the insertion plate;

[0013] Through the above technical solution, the spring can push the locking column downward under the action of elastic force and insert it into the locking hole to lock the insertion plate.

[0014] Furthermore, a fixing sleeve is fixedly connected to the outer side of the fixing joint, the left side of the fixing sleeve is fixedly connected to the right ends of a plurality of elastic plates at equal distances, and the left end of the elastic plate is fixedly connected to the left ends of the two locking sleeves respectively;

[0015] Through the above technical solution, since the elastic plate has an elastic effect, the snap-fit ​​sleeve can wrap and snap the sensor, thereby increasing the connection performance between the sensor and the fixed joint, and protecting the connection end at the same time.

[0016] The utility model has the following beneficial effects:

[0017] 1. In the utility model, firstly, the right end of the sensor side is inserted into the left end of the fixed joint, so that the sliders are slidably connected to the inner sides of the corresponding slide grooves, and the contact terminals are respectively inserted and connected to the inner sides of the corresponding terminal jacks. When the sensor is inserted, the upper and lower insertion plates are respectively inserted into the corresponding slots. At this time, the pressing block and the extension column are in a tightly pressed state, the position of the engaging column is above the inner part of the extension column, and the spring is compressed to align the position of the engaging hole with the bottom of the engaging column. Then the pressing state of the pressing block and the extension column is released. The spring pushes the engaging column downward under the action of elastic force and inserts it into the engaging hole to lock the insertion plate. The sensor can be fixed to the fixed joint to prevent the sensor from falling off. At the same time, it is convenient to quickly install and disassemble the sensor, avoiding the risk of the sensor falling off due to long-term loosening of the screws due to the traditional method of fixing with screws.

[0018] 2. In the utility model, when the sensor is docked with the fixed joint, the fixing sleeve, the elastic plate and the snap-fit ​​sleeve are first installed on the outside of the fixed joint through the fixing bolts. Then, when installing the sensor, the snap-fit ​​sleeves on the front and rear sides are pried apart by the elastic plate so that the snap-fit ​​sleeve is located on the outside of the right end of the sensor. Since the elastic plate has elastic effect, the snap-fit ​​sleeve can wrap and snap the sensor, thereby increasing the connection performance between the sensor and the fixed joint and protecting the connection end at the same time.
