Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of terminal crimping tools, in particular to a crimping tool for a process calibration instrument pen and a safety barrier connection terminal. Background Art
[0002] At present, the connection between production site signals and DCS systems is mainly achieved through Pepperl+Fuchs safety barriers, the front upper side of which is tilted to expose the wiring terminals, so that operators can use process calibrators to modify or check the parameters of field instruments. In the case that the original wiring cannot be removed, the operator needs to manually press the process calibrator's test lead to the head of the terminal fastening screw to achieve a temporary connection between the process calibration instrument pen and the safety barrier wiring terminal.
[0003] However, the above connection process has the following problems:
[0004] 1. The safety barrier wiring terminal is small, and the head of the fastening screw that compresses the original signal line is round, with a diameter of about 3mm and a cross groove. The surface area is limited, and it is difficult for the test lead of the process calibrator to establish a continuous and effective electrical connection with the wiring terminal of the safety barrier;
[0005] 2. If you want to establish a continuous and effective electrical connection between the test leads of the process calibrator and the wiring terminals of the safety barrier, two operators are required to coordinate and complete it. One of them manually presses the test leads of the process calibrator to the head of the wiring terminal fastening screw, and the other one operates the process calibrator to modify or check the on-site instrument parameters. This is very inefficient.
[0006] 3. In the process of manually pressing the test leads of the process calibrator onto the heads of the terminal fastening screws, it is very easy for the safety barrier terminals to loosen or fall off, thus causing unpredictable abnormal situations on site. Utility Model Content
[0007] In view of the deficiencies in the prior art, the utility model provides a crimping tool for a process calibration instrument pen and a safety barrier terminal, so as to solve the problem in the prior art that manually pressing the process calibration instrument pen and the safety barrier terminal requires coordination between two operators, resulting in very low efficiency and a safety hazard of the safety barrier terminal loosening or falling off.
[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0009] A crimping tool for a process calibration instrument pen and a safety barrier terminal, comprising:
[0010] A test lead fixing part, used for fixing the test leads of the process calibrator; and
[0011] The terminal locking portion is integrally formed with the probe fixing portion and is used to lock the crimping tool to the safety barrier to achieve crimping of the process calibration instrument pen and the safety barrier terminal.
[0012] In one embodiment disclosed in the present application, the test lead fixing portion has an overall appearance of a rectangular parallelepiped structure, and is provided with at least two circular holes for inserting the process calibration instrument pen;
[0013] The circular hole becomes a rectangular hole when extending along the length direction of the test lead fixing portion to the locking portion of the wiring terminal;
[0014] The width of the rectangular hole is smaller than the diameter of the circular hole, and is used to lock the tip of the test lead passing through the rectangular hole to prevent the test lead from retreating and popping out.
[0015] In one embodiment disclosed in the present application, the diameter of the circular hole is 6 mm.
[0016] In one embodiment disclosed in the present application, the number and spacing of the circular holes match the number and spacing of the safety barrier terminals.
[0017] In one embodiment disclosed in the present application, the locking portion of the wiring terminal is symmetrically provided with a pair of inclined platforms and plug plates connected to the inclined platforms;
[0018] The inclined surface of the inclined platform faces downward and is located between a pair of the plug boards, and is used to fit the upper side of the inclined front end of the safety barrier to press the pen tip of the process calibration instrument pen and the safety barrier wiring terminal;
[0019] The plug plate can be inserted into the gap between the modules on both sides of the safety barrier terminal to lock the crimping tool to the safety barrier.
[0020] In one embodiment disclosed in the present application, the outer edge of the plug board is in an arc-shaped structure.
[0021] In one embodiment disclosed in the present application, the thickness of the insert plate is 0.3-0.6 mm.

[0024] 1. Through the integrally formed test lead fixing part and terminal locking part, the crimping tool can be quickly locked to the safety barrier after fixing the process calibration instrument pen to realize the crimping of the process calibration instrument pen and the safety barrier terminal. In addition, the terminal locking part can improve the stability and tightness of the crimping point between the test lead and the terminal, thereby replacing the situation where an operator is dedicated to crimping the test lead and the terminal, saving 50% of the labor, and at the same time avoiding the safety hazards of loose or falling terminal terminals, greatly reducing the probability of personnel misoperation, and thus escorting the safe and stable operation of the process system.

[0034] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.
[0035] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0036] See also Figure 1 and Figure 2 As shown, the utility model provides a crimping tool for a process calibration instrument pen and a safety barrier terminal, comprising:
[0037] A test lead fixing portion 10, used for fixing the test leads of the process calibrator (not shown in the figure); and
[0038] The terminal locking portion 20 is integrally formed with the test lead fixing portion 10 and is used to lock the crimping tool to the safety barrier to achieve crimping of the process calibration instrument lead and the safety barrier terminal.
[0039] Specifically, in view of the structural characteristics of the process calibration instrument pen, the overall appearance of the test pen fixing part 10 is a rectangular structure, and at least two circular holes 11 are provided inside it for inserting the process calibration instrument pen. The circular hole 11 becomes a rectangular hole 12 when extending along the length direction of the test pen fixing part 10 to the terminal locking part 20. The width of the rectangular hole 12 is smaller than the diameter of the circular hole 11, and is used to lock the test pen tip passing through the rectangular hole 12 to prevent the test pen from retreating and popping out. In view of the structural characteristics that there is a gap between the modules on both sides of the safety barrier terminal, the terminal locking part 20 is symmetrically provided with a pair of inclined platforms 21 and a plug plate 22 connected to the inclined platform 21. The inclined surface of the inclined platform 21 faces downward and is located between the pair of plug plates 22, and is used to fit the upper side of the inclined front end of the safety barrier to crimp the pen tip of the process calibration instrument pen and the safety barrier terminal. The plug plate 22 can be inserted into the gap between the modules on both sides of the safety barrier terminal to lock the crimping tool to the safety barrier.
[0040] According to the conditions of the safety barrier terminal and the process calibration instrument pen, insert the test pen into the round hole 11. After the test pen tip passes through the rectangular hole 12, rotate the test pen so that the test pen tip cannot be ejected due to the obstruction of the rectangular hole 12, thereby fixing the test pen on the test pen fixing part 10; then, insert the plug plate 22 into the gap between the modules on both sides of the safety barrier terminal to lock the crimping tool to the safety barrier. The safety barrier terminal is surrounded by the terminal locking part 20 (plug plate 22), thereby achieving the fixation between the terminal locking part 20 and the safety barrier. At this time, the inclined surface of the ramp 21 is attached to the upper side of the inclined front end of the safety barrier, so that the test pen tip passing through the rectangular hole 12 is tightly crimped to the head of the safety barrier terminal fastening screw to establish a continuous and effective electrical connection. That is to say, through the integrally formed test lead fixing part 10 and the terminal locking part 20, the crimping tool can be quickly locked to the safety barrier after fixing the process calibration instrument pen to realize the crimping of the process calibration instrument pen and the safety barrier terminal, and the terminal locking part 20 can improve the stability and tightness of the crimping point between the test lead and the terminal, thereby replacing the situation where an operator is dedicated to crimping the test lead and the terminal, saving 50% of the labor, and at the same time avoiding the safety hazard of loose or falling terminal terminals, greatly reducing the probability of human error operation, and thus safeguarding the safe and stable operation of the process system.
[0041] In this embodiment, the diameter of the circular holes 11 is 6 mm. The number and spacing of the circular holes 11 match the number and spacing of the safety barrier terminals.
[0042] See also Figure 2 As shown, the outer edge of the plug board 22 is in an arc-shaped structure. In this way, it can be inserted into the gap between the modules on both sides of the safety barrier terminal better and faster, thereby improving the operating efficiency.
[0043] The thickness of the plug board 22 varies according to the size of the gap between the modules on both sides of the safety barrier terminal. In this embodiment, the thickness of the plug board 22 is 0.3-0.6 mm.
[0044] In order to improve the safety of the crimping tool, the integrally formed test lead fixing portion 10 and the terminal locking portion 20 are made of an insulating material (such as rubber).
[0045] The above embodiments are only preferred embodiments of the present utility model and are not limitations on the technical solutions of the present utility model. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present utility model.
