Abstract
Description
Technical Field
[0001] This utility model belongs to the field of terminal production technology, and in particular relates to terminal testing tooling. Background Technology
[0002] Terminals are important contact parts of electronic connectors. These terminals are like small connectors, connecting devices with the same or different functions to ensure that some components can operate smoothly or that current can flow smoothly, so that the whole device can operate. To ensure the stable performance of terminals, it is necessary to fix the terminals with testing fixtures and test their appearance, function, etc., thereby improving product quality.
[0003] A search revealed CN221077572U, with an application date of October 31, 2023, which discloses a terminal testing fixture. The terminal testing fixture includes: a base plate; a mounting base is placed on one end of the base plate; a placement platform is fixedly mounted on the middle of the mounting base; several fastening blocks are slidably disposed on one side of the placement platform; a clamping groove is formed between two fastening blocks; threaded holes are formed on both sides of the placement platform; locking rods are disposed inside the threaded holes; the locking rods have external threads and engage with the threaded holes through the external threads; locking heads are fixedly mounted on one side of each of the two locking rods; the two locking heads are respectively in close contact with the outer sides of the fastening blocks on both sides; two fixing plates are fixedly mounted on the end of the base plate opposite to the mounting base; a threaded rod is rotatably disposed between the two fixing plates; one end of the threaded rod passes through the fixing plate and extends to the outer side of the fixing plate.
[0004] However, it still has the following drawbacks in practical use:
[0005] 1. The existing terminal testing fixture uses a locking rod to adjust the position of the locking head to clamp the terminal. This method is cumbersome, time-consuming, labor-intensive, and inefficient for operators.
[0006] 2. Existing terminal testing fixtures can only place the terminals flat on the fixture surface during use, resulting in a small testing range and limited functionality, thus restricting their applicability. Therefore, we have provided a terminal testing fixture to address the aforementioned problems. Utility Model Content
[0007] The purpose of this utility model is to provide a terminal inspection fixture. By setting a limiting component, under the elastic action of the torsion spring, two sets of L-shaped clamping plates can rotate around the rotating rod as the center, realizing or releasing the limiting effect of the L-shaped clamping plates on the groove of the opposite rod. This makes it convenient for workers to quickly realize or release the clamping and limiting measures on the terminals, saving time and effort and increasing work efficiency. In addition, by using the adjustment component, the terminal frame can be rotated around the first rotating shaft and the second rotating shaft to adjust the angle. The terminal frame can be rotated 90 degrees and placed vertically on the surface of the fixture body. The CCD lens can be used to check whether the terminals are deformed, have foreign objects, are damaged, are not inserted properly, or have other defects such as spring clips, thus increasing functionality and applicability.
[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0009] This utility model is a terminal testing fixture, including a fixture body and a terminal frame disposed on one side of its upper surface. Clamping blocks are slidably mounted in an array from front to back on the inner wall of the terminal frame. Square holes are opened on one side of the front and rear end faces of the terminal frame. L-shaped grooves are opened on the inner walls of both sides of the square holes. Limiting components are provided inside the L-shaped grooves. An adjustment component is provided at one end of the terminal frame.
[0010] The limiting assembly includes a first pressure handle and a second pressure handle disposed at both ends above the terminal frame. A first connecting rod is fixedly disposed at the bottom front end of the first pressure handle, and a second connecting rod is fixedly disposed at the bottom rear end of the second pressure handle.
[0011] The adjustment assembly includes a first rotating plate fixed to the front end of one side wall of the terminal frame, and a second rotating plate symmetrically arranged at the rear end of the first rotating plate, with one end of the second rotating plate fixed to the rear end of one side wall of the terminal frame.

[0013] The present invention is further configured such that a square rod is fixed at the center of the inner wall of the push plate, and the other end of the square rod slides through the square hole and connects to the pressure plate.
[0014] The present invention is further configured such that a spring is sleeved on the outer wall of the square rod, and the spring is located between the outer wall of the terminal frame and the push plate.
[0015] The present invention is further configured such that an L-shaped retaining plate is fixedly provided at the bottom end of both the first connecting rod and the second connecting rod, and the center positions of both the first connecting rod and the second connecting rod are rotatably sleeved on the outer wall of the rotating rod.

[0019] This utility model has the following beneficial effects:
[0020] 1. This utility model, by setting a limiting component, allows two sets of L-shaped clamping plates to rotate around the rotating rod under the elastic action of the torsion spring, thereby achieving or releasing the limiting effect of the L-shaped clamping plates on the grooves of the opposite rod.

Detailed Implementation
[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0031] Example 1
[0032] Please see Figures 1 to 4 This utility model is a terminal testing fixture, including a fixture body 100 and a terminal frame 103 disposed on one side of its upper surface. Clamping blocks 103a are slidably mounted in an array from front to back on the inner wall of the terminal frame 103. Square holes 103b are opened on one side of the front and rear end faces of the terminal frame 103. L-shaped grooves 103c are opened on the inner walls of both sides of the square holes 103b. Limiting components 200 are disposed inside the L-shaped grooves 103c. The limiting components 200 include a first pressure handle 201 and a second pressure handle 202 disposed at both ends above the terminal frame 103. A first connecting rod 201a is fixedly disposed at the bottom front end of the first pressure handle 201, and a second connecting rod 202a is fixedly disposed at the bottom rear end of the second pressure handle 202.
[0033] Specifically, a wire clamping plate 101 is slidably mounted on the other side of the upper surface of the fixture body 100. A tensioning component 102 is provided inside the wire clamping plate 101. Push plates 104 are provided on the outer sides of the front and rear ends of the terminal frame 103. A square rod 105 is fixed at the center of the inner wall of the push plate 104. The other end of the square rod 105 slides through the square hole 103b and connects to the pressure plate 106. A spring 105a is sleeved on the outer wall of the square rod 105, and the spring 105a is located on the terminal frame. Between the outer wall of 103 and the push plate 104; L-shaped clamping plates 205 are fixed at the bottom ends of the first connecting rod 201a and the second connecting rod 202a, and the center positions of the first connecting rod 201a and the second connecting rod 202a are rotatably sleeved on the outer wall of the rotating rod 203; a torsion spring 203a is sleeved in the middle of the outer wall of the rotating rod 203, and the front and rear ends of the rotating rod 203 are respectively installed on the inner walls of the adjacent side plates 204, and the bottom of the side plates 204 is fixed on the surface of the terminal frame 103.
[0034] Furthermore, a limiting hole is formed on the surface of the fixture body 100, the position of which corresponds to the position of the sliding hole 304a at the lowest end of the disc 304. The clamping plate 101 and the tensioning assembly 102 are existing technologies, so they will not be described in detail here. The first connecting rod 201a and the second connecting rod 202a respectively connect the first pressure handle 201 and the L-shaped clamping plate 205 and the second pressure handle 202 and the L-shaped clamping plate 205, which play a role in connecting and transmitting. The outer wall of the square rod 105 is provided with slots evenly spaced, and its internal area is slightly larger than the end area of the L-shaped clamping plate 205.
[0035] The operation process of this embodiment is as follows: The operator first places the terminals between adjacent clamping blocks 103a in sequence, then applies force to the first pressure handle 201 and the second pressure handle 202. The first pressure handle 201 and the second pressure handle 202 move towards the center under the force, and cause the first connecting rod 201a and the second connecting rod 202a to rotate around the rotating rod 203, and compress the torsion spring 203a. At this time, the rotation of the first connecting rod 201a and the second connecting rod 202a will drive the corresponding L-shaped clamping plate 205 to rotate, so that the L-shaped clamping plate 205 rotates and moves out of the slot on the square rod 105, releasing the limitation of the square rod 105. Then the operator can apply force to the push plate 104. Under the action of the square rod 105, the push plate 106 is pushed to compress the clamping block 103a located on the outside. The 04 movement engages with the outer wall of the terminal frame 103 to compress the spring 105a, causing multiple sets of clamping blocks 103a to move and clamp the terminal. After the terminal is positioned, the force applied to the first pressure handle 201 and the second pressure handle 202 stops. At this time, under the elastic action of the torsion spring 203a, the two sets of L-shaped clamping plates 205 spring back to the corresponding slots on the outer wall of the square rod 105 with the rotating rod 203 as the center, and limit the position of the square rod 105 after adjustment. When it is necessary to release the clamping block 103a from the terminal clamping limit, only the first pressure handle 201 and the second pressure handle 202 need to be pressed. Under the elastic action of the spring 105a, the pressure plate 106 will automatically pop out, which makes it easy for the staff to quickly realize or release the clamping limit of the terminal, saving time and effort and increasing work efficiency.
[0036] Example 2
[0037] Please see Figure 2 and Figure 5 Based on Embodiment 1, unlike the first embodiment, an adjustment component 300 is provided. The adjustment component 300 includes a first rotating plate 301 fixedly disposed at the front end of one side wall of the terminal frame 103, and a second rotating plate 302 symmetrically disposed at the rear end of the first rotating plate 301. One end of the second rotating plate 302 is fixedly disposed at the rear end of one side wall of the terminal frame 103. This solves the problem that the existing terminal detection fixture can only place the terminal flat on the surface of the fixture when in use, resulting in a small detection range, single function, and limited applicability.
[0038] Specifically, a second rotating shaft 302a is fixedly provided on the rear end face of the second rotating plate 302, and the other end of the second rotating shaft 302a is rotatably installed in the bearing seat. A first rotating shaft 301a is fixedly provided on one side of the front end face of the first rotating plate 301. The other end of the first rotating shaft 301a passes through the bearing on the fixed seat 303 and is connected to the disc 304. Sliding holes 304a are evenly spaced along the circumferential direction of the outer wall of the disc 304. A locking rod 305 is slidably installed inside the sliding holes 304a.
[0039] Furthermore, the terminal frame 103 can be rotated around the first rotating shaft 301a and the second rotating shaft 302a under force, and the angle of the terminal frame 103 can be adjusted. The locking rod 305 can slide out of the sliding hole 304a, so that it can be adjusted to the appropriate sliding hole 304a according to the angle of the terminal frame 103.
[0040] The operation process of this embodiment is as follows: After the terminal is clamped and fixed, the wire clamping plate 101 and the tensioning component 102 are used to clamp and limit the wire. After the operator has completed the inspection of the crimping height and flatness of the terminal and the wire, force is applied to the terminal frame 103 to make it rotate around the first rotating shaft 301a and the second rotating shaft 302a as the center. The terminal frame 103 is rotated 90 degrees and placed vertically on the surface of the fixture body 100. Then, the locking rod 305 and the sliding hole 304a are used to limit the disc 304 to achieve the purpose of fixing the angle of the terminal frame 103. Then, the operator can use the CCD lens to check whether the terminal is deformed, has foreign objects, is damaged, is not inserted enough, or has springs and other defects, thereby increasing functionality and applicability.
