Description

Technical Field

[0001] The utility model relates to the technical field of terminal machine pressure sensors, in particular to a European-style punch pressure sensor structure. Background Art

[0002] As a relatively special terminal machine, the European-style terminal machine also occupies a considerable market share. The punch of the European-style terminal machine is connected to the die by a converter. When using it, it is necessary to replace the die of a different brand, and the converter must also be replaced. The force point of the base plate also changes, so the selection of pressure sensors is limited to punch sensors or wall sensors. The contact surface between the European standard punch and the die converter is a card-type force plane with two force-bearing areas on the plane. During use, a single force-bearing area will be subjected to force. Ordinary European-style punch sensors are usually split middle assembly type or single-side installation type, which may result in unconcentrated force or sometimes no force.

[0003] Therefore, the existing technology has defects and needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a European-style punch pressure sensor structure.

[0005] The technical solution of the present utility model is as follows: A European punch pressure sensor structure is provided, including: a sensor lower shell, a sensor upper shell covering the sensor lower shell, a sensor mounting groove arranged on the contact surface between the sensor lower shell and the sensor upper shell, and a contact step position arranged on the bottom surface of the sensor upper shell, a sensor is installed and placed in the sensor mounting groove, the contact step position contacts the sensor, and the contact step position lifts the sensor upper shell, so that a gap is formed between the sensor upper shell and the sensor on both sides of the contact step position.

[0006] Furthermore, the sensor lower shell is provided with a plurality of threaded holes, and the sensor upper shell is provided with countersunk holes corresponding to the threaded holes. Screws are passed through the countersunk holes and locked in the threaded holes to achieve the connection and fixation between the sensor lower shell and the sensor upper shell. The threaded holes and countersunk holes are arranged at corresponding positions of the contact step positions.

[0007] Furthermore, the sensor lower shell and the sensor upper shell are correspondingly provided with mounting holes, and the mounting holes are provided at positions corresponding to the contact step positions.

[0008] Furthermore, the bottom of the sensor lower shell forms a U-shaped buckle structure.

[0009] Furthermore, a protruding force collecting structure is provided at the bottom of the lower housing of the sensor.

[0010] Furthermore, a line-changing module is provided on the side wall of the sensor lower shell or the side wall of the sensor upper shell, and a line-passing groove is provided on the sensor lower shell between the corresponding sensor installation groove and the line-changing module.

[0011] By adopting the above scheme, the utility model contacts the sensor through the contact step. When the upper shell of the sensor is subjected to force, it deforms to both sides of the contact step with the contact step as the fulcrum. The deformation caused by the gap on both sides of the contact step is detected by the sensor, so that a stable piezoelectric signal can be received and transmitted to the pressure management monitoring system as data for analysis to ensure the quality of terminal crimping.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] See also Figures 1 to 3 The utility model provides a European-style punch pressure sensor structure, comprising: a sensor lower shell 1, a sensor upper shell 2 covering the sensor lower shell 1, a sensor mounting groove 11 provided on the contact surface between the sensor lower shell 1 and the sensor upper shell 2, and a contact step 21 provided on the bottom surface of the sensor upper shell 2. A sensor is mounted in the sensor mounting groove 11, and the contact step 21 contacts the sensor. The contact step 21 lifts the sensor upper shell 2, so that a gap is formed between the sensor upper shell 2 and the sensor on both sides of the contact step 21.

[0019] When the sensor upper shell 2 is stressed, it deforms to both sides of the contact step position 21, taking the contact step position 21 as the fulcrum, and the deformation of the gap on both sides of the contact step position 21 is detected by the sensor, so that a stable piezoelectric signal can be received and transmitted to the pressure management monitoring system as data for analysis, ensuring the quality of terminal crimping. While retaining the original size of the original punch sensor, high-strength materials are used to achieve the maximum contraction of the point area while ensuring the strength of the workpiece. In addition, the design of the contact step position 21 allows the sensor position to deform easily under stress without the influence of the reaction force, achieving high sensitivity.

[0020] Please refer to Figure 1 、 Figure 4 、 Figure 5 , the figure is the structure of three common European punch sensors. Without changing the original punch size, the punch sensor is improved to meet the adaptability with the European punch.

[0021] In some embodiments, a plurality of threaded holes 12 are provided on the sensor lower shell 1, and the sensor upper shell 2 is provided with a countersunk hole 22 corresponding to the threaded hole 12. The threaded hole 12 and the countersunk hole 22 are arranged at the corresponding position of the contact step position 21. By screwing the screw through the countersunk hole 22 and locking it in the threaded hole 12, the connection and fixation between the sensor lower shell 1 and the sensor upper shell 2 are achieved. By arranging the threaded hole 12 and the countersunk hole 22 at the corresponding position of the contact step position 21, the connection and fixation between the sensor upper shell 2 and the sensor lower shell 1 are achieved while avoiding deformation of the positions on both sides of the corresponding contact step position 21 of the sensor upper shell 2 before detection, which affects the detection effect of the sensor.

[0022] In some embodiments, the sensor lower shell 1 and the sensor upper shell 2 are correspondingly provided with a mounting hole 13, which is arranged at the corresponding position of the contact step position 21. The mounting hole 13 is arranged at the corresponding position of the contact step position 21. By screwing the screw through the mounting hole 13 and locking it with the equipment machine, the mounting and fixation of the sensor structure are achieved.

[0023] In some embodiments, the bottom of the sensor lower shell 1 forms a U-shaped buckle structure 14, which is convenient for connecting with the lower mold. After the mold is pressed to crimp the terminal, the workpiece is pulled up.

[0024] In some embodiments, the bottom of the sensor lower shell 1 is provided with a protruding force collecting structure 15, which can be connected with the lower component and directly stressed during the crimping process, providing effective support for the sensor lower shell 1.

[0025] In some embodiments, a line-changing module 3 is provided on the sidewall of the sensor lower housing 1 or the sidewall of the sensor upper housing 2. A line-passing slot 111 is provided on the sensor lower housing 1 between the corresponding sensor mounting slot 11 and the line-changing module 3. When the sensor is installed in the sensor mounting slot 11, the sensor's transmission line is extended along the line-passing slot 111 to the line-changing module 3 for wiring. This facilitates communication between the sensor and the pressure management and monitoring system, meeting the transmission requirements of detection data.

[0026] To sum up, the utility model contacts the sensor through the contact step. When the upper shell of the sensor is subjected to force, it deforms to both sides of the contact step with the contact step as the fulcrum. The deformation caused by the gap on both sides of the contact step is detected by the sensor, so that a stable piezoelectric signal can be received and transmitted to the pressure management monitoring system as data for analysis to ensure the quality of terminal crimping.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
