Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of connectors, in particular to a POGO PIN height testing device. Background Art
[0002] A connector generally refers to an electrical connector, that is, a device that connects two active devices to transmit current or signals. Connectors are widely used in various types of electronic and electrical equipment. Based on different application scenarios and needs, connectors have many different types, such as plugs for transmitting electrical energy, high-speed connectors for transmitting data (such as SFP, QSFP, OSFP, SAS and other types of connectors), or USB connectors for both data transmission and charging. In some USB connectors used for charging, different connection structures are designed according to the needs of different electrical products, such as attached Figure 3 The USB charging connector shown, in addition to the USB plug connector, is also provided with a POGO PIN (i.e., a spring pin) in the recessed part. In order to ensure the subsequent normal use, the height of the spring pin exposed from the recessed part has a high precision requirement. Therefore, after the product is produced, the height of the spring pin needs to be measured to ensure that the product meets the design requirements. At present, the dimension measurement of this type of product can usually be carried out in a non-contact manner, such as using optical irradiation or radiography to measure the dimension. However, since the spring pin of the product is surrounded by opaque plastic, the above-mentioned non-contact measurement method cannot be used. If the measurement is performed manually using a measuring tool such as a micrometer and direct contact, it is easy to exceed the trigger force of the spring pin and change the height of the spring pin, affecting the accuracy of the measurement result. Although there are also devices on the market that can automatically measure the dimension, the structure is relatively complex, the cost of use is high, and it is difficult to adapt to the above-mentioned USB charging connector.

DETAILED DESCRIPTION
[0020] In order to facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below in conjunction with specific embodiments and drawings.
[0021] Example 1
[0022] Reference Figure 1 This embodiment provides a POGO PIN height test device, including a test bench, a support column arranged on the test bench, a fine-tuning rod connected to the support column, a micrometer connected to the fine-tuning rod, a socket arranged on the test bench, and a controller arranged on one side of the test bench; the socket and the controller are electrically connected, and the probe of the micrometer is electrically connected to the controller. Since the socket and the controller, the probe and the controller are all electrically connected, when the probe contacts the POGO PIN, the controller receives a conduction signal, thereby avoiding exceeding the trigger force of the POGO PIN during the measurement process and ensuring the accuracy of the measurement result.
[0023] The probe of the micrometer is connected to the bottom end of the fine-tuning rod by a connecting rod. The fine-tuning rod has a rotating wheel. When the rotating wheel is rotated, the lower end of the fine-tuning rod can move downward. Since the lower end of the fine-tuning rod and the probe of the micrometer are connected by the connecting rod, when the fine-tuning rod is adjusted, the probe of the micrometer will move with the fine-tuning rod. In addition, the connecting rod and the probe of the micrometer can be set to a detachable connection mode. When the connecting rod and the probe are separated, the probe of the micrometer can move quickly to achieve fast measurement.
[0024] A fixed bracket is arranged on the support column, and the fixed bracket includes a first connecting part connected to the support column, a first connecting arm connected to the first connecting part, a second connecting arm connected to the first connecting arm, a second connecting part arranged at the end of the first connecting arm, and a third connecting part arranged at the end of the second connecting arm; the micrometer is connected to the second connecting part, and the fine-tuning rod is connected to the third connecting part.
[0025] The controller is provided with a buzzer. The buzzer can emit a buzzing sound to remind the staff, such as reminding that the probe is in contact with the POGO PIN, or reminding that the test is qualified or unqualified. The micrometer is a digital micrometer. The controller is provided with an indicator light, which can cooperate with the buzzer to light up to remind the staff.
[0026] During the test, first insert the product to be tested into the socket, adjust the dial gauge probe to the inner concave surface of the product, and reset the dial gauge to zero. Then connect the dial gauge probe to the connecting rod and adjust the probe to the top of the POGO PIN. Then adjust the fine-tuning screw to gradually bring the probe closer to the top of the POGO PIN. When the digital dial gauge probe and the POGO PIN are in instant contact, the buzzer and LED indicator will sound and light up respectively. At this time, the size displayed by the digital dial gauge is the height size of the object to be tested.
[0027] Example 2
[0028] Reference Figure 2 This embodiment provides a POGO PIN height test device, including a test bench, a support column arranged on the test bench, a fine-tuning rod connected to the support column, a micrometer connected to the fine-tuning rod, a socket arranged on the test bench, and a controller arranged on one side of the test bench; the socket and the controller are electrically connected, and the probe of the micrometer is electrically connected to the controller. Since the socket and the controller, the probe and the controller are all electrically connected, when the probe contacts the POGO PIN, the controller receives a conduction signal, thereby avoiding exceeding the trigger force of the POGO PIN during the measurement process and ensuring the accuracy of the measurement result.
[0029] The probe of the micrometer is connected to the bottom end of the fine-tuning rod by a connecting rod. The fine-tuning rod has a rotating wheel. When the rotating wheel is rotated, the lower end of the fine-tuning rod can move downward. Since the lower end of the fine-tuning rod and the probe of the micrometer are connected by the connecting rod, when the fine-tuning rod is adjusted, the probe of the micrometer will move with the fine-tuning rod. In addition, the connecting rod and the probe of the micrometer can be set to a detachable connection mode. When the connecting rod and the probe are separated, the probe of the micrometer can move quickly to achieve fast measurement.
[0030] A fixed bracket is arranged on the support column, and the fixed bracket includes a first connecting part connected to the support column, a first connecting arm connected to the first connecting part, a second connecting arm connected to the first connecting arm, a second connecting part arranged at the end of the first connecting arm, and a third connecting part arranged at the end of the second connecting arm; the micrometer is connected to the second connecting part, and the fine-tuning rod is connected to the third connecting part.
[0031] The controller is provided with a buzzer. The buzzer can emit a buzzing sound to remind the staff, such as reminding that the probe is in contact with the POGO PIN, or reminding that the test is qualified or unqualified. The micrometer is a digital micrometer. The controller is provided with an indicator light, which can cooperate with the buzzer to light up to remind the staff.
[0032] The POGO PIN height testing device includes a conveyor belt disposed on the testing table for conveying products.
[0033] The POGO PIN height testing device includes a plug assembly disposed on the test bench for inserting a product into a socket, the plug assembly includes a linear drive, and a clamping drive connected to the output end of the linear drive, the linear drive drives the clamping drive to move closer to or away from the socket. The linear drive is a cylinder, specifically a double-stroke cylinder, and the clamping drive is a claw cylinder. Of course, during specific implementation, the linear drive can also be a drive that can achieve linear drive, such as a lead screw, an electric cylinder, etc. The output end of the claw cylinder can be connected to a clamp that matches the product specifications, so as to accurately clamp the product.
[0034] The conveyor belt can be used to convey the product to be tested. When the product reaches the position corresponding to the socket, the linear drive member drives the clamping drive member to move to the position corresponding to the product and clamps the product from both sides. At this time, the product is also centered at the same time. Then the clamping drive member continues to move toward the socket until the product is inserted into the socket.
[0035] During the test, the conveyor belt conveys the product to the position corresponding to the socket. The linear drive of the plug assembly drives the clamping drive to move toward the product. After the clamping drive clamps the product, the linear drive continues to drive the clamping drive to move toward the socket, inserting the product to be tested into the socket, and then adjust the micrometer probe to the inner concave surface of the product, and reset the micrometer to zero. Then connect the probe of the micrometer to the connecting rod, and adjust the probe to above the POGO PIN. Then adjust the fine-tuning screw to gradually approach the top of the POGO PIN. When the digital display micrometer probe and the POGOPIN are in instantaneous contact, the buzzer and LED indicator will sound and light up respectively. At this time, the size displayed by the digital display micrometer is the height size of the object to be measured.
[0036] The utility model is provided with a micrometer and a fine-adjustment rod, the bottom of the fine-adjustment rod is connected to the probe of the micrometer through a connecting rod, so that the position of the probe can be fine-tuned, and the socket and the probe are both connected to a controller, so that a feedback signal can be received and a measurement result can be obtained at the moment the probe contacts the POGO PIN, so that the trigger force of the POGO PIN is avoided from being exceeded during contact measurement, and the accuracy of the measurement result is guaranteed, thereby ensuring product quality.
