Description

Technical Field

[0001] The utility model relates to the technical field of connector detection, in particular to a device for detecting long and short pins of a connector. Background Art

[0002] Connectors are also often called circuit connectors, electrical connectors, which are conductor devices that bridge two conductors in a loop so that current or signals can flow from one conductor to another. Electronic connectors are a type of motor system that provides a separable interface for connecting two sub-electronic systems. Simply put, the components used to complete the electrical connection between circuits or electronic machines become connectors, which are the bridges between the two.

[0003] Typically, electronic connectors consist of a plastic body and terminals. Before assembly, these two components are separated and require automated machinery to assemble them together. Currently, after assembly, inspection systems must verify the length and height of the terminals. Since the electrical conductivity of connectors is determined by the pins, ensuring the pins are securely inserted into the housing is crucial to product performance. Currently, pin length in these connectors can only be determined using high-definition silicon or visual inspection, which is inefficient, has a high error rate, and is costly.

[0004] In view of this, it is necessary to propose further improvements to the current structure. Utility Model Content

[0031] Please refer to Figures 1 to 6 The utility model provides a device for detecting the length of a connector pin, comprising:

[0032] Base 1;

[0033] The moving part 3 is arranged on the base 1;

[0034] The detection assembly 4 is connected to the movable member 3 and includes a plurality of detection members 41 and a plurality of detection members 42. The plurality of detection members 42 are relatively arranged on both sides of the plurality of detection members 41, and each detection member 41 is provided with a groove 4131. The movable member 3 can drive the plurality of detection members 41 to correspondingly abut or move away from each long and short pin 21 of the connector 2, and link the groove 4131 to move closer to or away from the position of the detection member 42, so that light between the plurality of relatively arranged detection members 42 can pass through or move away from the groove 4131.

[0035] In this embodiment, the detection device for the length and short pins of the connector includes a base 1, and a movable part 3 is provided on the base 1. A detection component 4 is connected to the movable part 3. The detection component 4 includes multiple detection parts 41 and multiple detection parts 42. The movable part 3 can drive the detection component 4 to perform horizontal reciprocating motion, that is, drive the detection component 4 closer to or away from the connector 2. Specifically, the movable part 3 can drive the multiple detection parts 41 in the detection component 4 to abut against each long and short pin of the connector 2. The number of detection parts 41 is the same as the number of long and short pins of the connector 2, that is, each detection part 41 corresponds to one long and short pin, so that it can detect whether the heights of the long and short pins of the connector 2 are consistent, and whether there is any abnormality.

[0036] Specifically, multiple detection members 42 are disposed on either side of the multiple detection members 41. Each detection member 41 is provided with a groove 4131. The movable member 3 can drive the multiple detection members 41 toward or away from the connector 2. When the movable member 3 drives the detection member 41 to move horizontally, the groove 4131 on the detection member 41 also moves with the movement of the movable member 3. This allows the groove 4131 on the detection member 41 to move toward or away from the detection members 42 disposed on either side of the detection member 41, thereby allowing light between the detection members 42 disposed oppositely on either side of the detection member 41 to pass through or not pass through the groove 4131. If the groove 4131 is close to and corresponds to the position of the detection member 42, light between the multiple detection members 42 disposed oppositely can pass through the groove 4131.

[0037] Specifically, the embodiment of the present application determines the height consistency of the connector 2 by determining whether light between a plurality of relatively arranged detection members 42 can pass through the groove 4131 of the detection member 41 that abuts the connector 2. This can effectively detect height differences in the connector greater than 0.2 mm. When it is necessary to detect the consistency of the length and short pins of the connector 2 or whether a pin is missing, the detection member 41 in the detection assembly 4 is first driven by the moving member 3 to abut the length and short pins of the connector 2. The groove 4131 on the detection member 41 moves toward the connector 2. When the detection member 41 and the length and short pins of the connector 2 are in contact, the detection members 42 on both sides of the detection member 41 are fixed on both sides of the detection member 41 and will not move due to the movement of the detection member 41. Among them, if the height consistency of the length and short pins of the connector 2 is good, that is, the height of the length and short pins of the connector 2 is at the standard height, the position of the groove 4131 on the detection member 41 will exactly correspond to the position of the relatively arranged detection member 42, and the relatively arranged detection member 42 will detect. If the connector 2 is good, and the light emitted by the detection components 42 on both sides can pass through the groove 4131, and the detection components 42 on both sides can receive the light from the opposite side, then the connector 2 is good. If the heights of the long and short pins of the connector 2 are inconsistent or missing, that is, the lengths of the long and short pins are too long or too short than the standard height, the individual detection components 41 will be displaced, and the groove 4131 on the detection component 41 will also be displaced, that is, the position of the groove 4131 will not correspond to the position of the detection component 42, that is, the position of the groove 4131 will be away from the position of the detection component 42, and the light from the opposite detection component 42 will not be able to pass through the displaced groove 4131 or the light will be blocked by the groove 4131, then the connector 2 is defective. If the groove 4131 on even one detection component 41 among the multiple detection components 41 is not light-transmissive, the connector 2 is also defective.

[0038] The detection element 41 is a detection probe.

[0039] Furthermore, the detection component 42 is a fiber optic sensor, and the base 1 is further provided with a fiber optic amplifier 5 , which is electrically connected to the plurality of fiber optic sensors 42 .

[0040] In this embodiment, the detection component 42 is specifically a fiber optic sensor, and a fiber optic amplifier 5 is also connected to the base 1. The fiber optic amplifier 5 is electrically connected to multiple fiber optic sensors 42 through wires. The fiber optic amplifier 5 is used to determine whether the light emitted by the fiber optic sensor on one side can pass through the groove 4131 and be received by the fiber optic sensor on the other side, thereby being used to determine whether the heights of the long and short pins on the connector 2 are consistent. If the light of the fiber optic sensor is blocked, the fiber optic sensor will send a signal to the fiber optic amplifier 5, and it will be determined whether the connector 2 is good or defective. If the light can pass through the groove 4131 on the detection component 41, it is a good product. As long as there is a groove 4131 on the detection component 41 that cannot pass light, it is a defective product.

[0041] Furthermore, the detection assembly 4 includes a connecting base 43, the moving member 3 is connected to the connecting base 43 and drives the connecting base 43 to move closer to or away from the connector 2, multiple detection members 41 penetrate the connecting base 43 and can make horizontal reciprocating motion relative to the connecting base 43, multiple detection members 42 are fixedly arranged on both sides of the connecting base 43, and multiple through holes 433 are respectively opened on the two side walls of the connecting base 43, and a detection member 42 is connected to each through hole 433.

[0042] In this embodiment, the detection assembly 4 further includes a connecting seat 43, which is connected to the moving member 3, so that the moving member 3 can drive the connecting seat 43 to perform horizontal reciprocating motion, that is, drive the connecting seat 43 toward or away from the connector 2. A plurality of detection members 41 are also connected through the connecting seat 43, and the plurality of detection members 41 can also perform horizontal reciprocating motion relative to the connecting seat 43. When the moving member 3 drives the detection members 41 on the connecting seat 43 to perform horizontal reciprocating motion, that is, drives the detection members 41 to abut against or away from the connector 2, so that when the detection members 41 abut the connector 2, the abutting force causes the detection members 41 to move in a direction away from the connector 2. When the detection members 41 move away from the connector 2, the abutting force is lost, and the detection members 41 need to move in a direction toward the connector 2.

[0043] Specifically, a plurality of detection components 42 are fixedly connected to both sides of the connecting seat 43, and a plurality of through holes 433 are provided on both side walls of the connecting seat 43. A detection component 42 is connected in each through hole 433, so that the detection component 42 can pass through the through hole 433, and then the light of the detection component 42 can pass through the groove 4131 on the detection component 42 through the through hole 433.

[0044] Furthermore, each detection member 41 is sleeved with an elastic member 4121. When the elastic member 4121 is compressed, the detection member 41 is tightly abutted against the long and short pins 21 of the connector 2. The grooves 4131 on the detection member 41 correspond to the positions of the multiple detection members 42, so that light from the multiple detection members 42 can pass through the grooves 4131.

[0045] In this embodiment, each detection member 41 is provided with an elastic member 4121. When the moving member 3 drives the detection member 41 to move toward the direction of the connector 2, the multiple detection members 41 will be tightly abutted against each long and short pin on the connector 2. At this time, the elastic member 4121 on the detection member 41 is compressed, and the detection member 41 will be displaced in the direction away from the connector 2 under the action of the squeeze. When the long and short pins of the connector 2 are normal, when the detection member 41 abuts against the normal long and short pins of the connector 2, the groove 4131 on it can be aligned with the corresponding The positions of the detection members 42 are set to correspond, and the light between the relatively set detection members 42 will pass through the groove 4131; when the long and short pins of the connector 2 are missing or the heights are inconsistent, when the detection member 41 abuts against the long and short pins of the abnormal connector 2, some or more of the multiple detection members 41 will be displaced, that is, the groove 4131 on the displaced individual or multiple detection members 41 will not correspond to the position of the detection member 42, and the light of the detection member 42 will not pass through the groove 4131, and the connector 2 will be detected as defective.

[0046] Specifically, when the detection of the connector 2 is completed, the moving part 3 will drive the detection part 41 to move in the direction away from the connector 2, and the detection part 41 will move away from the long and short pins of the connector 2. The elastic part 4121 sleeved on the detection part 41 will return to its original state, thereby driving the detection part 41 to move in the direction close to the connector 2.

[0047] The elastic member 4121 in this embodiment is specifically a compression spring.

[0048] Furthermore, any detection component 41 includes a first detection portion 411, a second detection portion 412, a third detection portion 413 and a fourth detection portion 414 that are interconnected. The second detection portion 412 is sleeved with an elastic member 4121, the third detection portion 413 is provided with a groove 4131, and the fourth detection portion 414 can abut against the long and short pins 21 of the connector 2.

[0049] In this embodiment, each detecting member 41 includes a first detecting portion 411, a second detecting portion 412, a third detecting portion 413, and a fourth detecting portion 414, which are sequentially connected. The connection method of the first detecting portion 411, the second detecting portion 412, the third detecting portion 413, and the fourth detecting portion 414 is not limited herein; in the embodiment of the present application, the connection method is integrally formed. The second detecting portion 412 is provided with an elastic member 4121, and the third detecting portion 413 is provided with a groove 4131. When the moving member 3 drives the detecting member 41 toward the connector 2, the fourth detecting portion 414 abuts against the long and short pins 21 of the connector 2.

[0050] Furthermore, the connecting base 43 is provided with a first slot 431 and a second slot 432, the first detection portion 411 and the fourth detection portion 414 are exposed on the connecting base 43, the second detection portion 412 which is sleeved with the elastic member 4121 is arranged in the first slot 431, the third detection portion 413 which is provided with a groove 4131 is arranged in the second slot 432, and a plurality of through holes 433 are respectively provided on the two side walls of the second slot 432 which are opposite to each other.

[0051] In this embodiment, the connecting base 43 is provided with a first slot 431 and a second slot 432. The first detecting portion 411, the second detecting portion 412, the third detecting portion 413, and the fourth detecting portion 414 of the detecting element 41 sequentially extend through the connecting base 43. The first detecting portion 411 is exposed outside the connecting base 3, the second detecting portion 412, which is sheathed with an elastic member 4121, is disposed in the first slot 431 of the connecting base 43, and the third detecting portion 413, which is provided with a groove 4131, is disposed in the second slot 432 of the connecting base 43. Through holes 433 are respectively formed on the two side walls of the second slot 432 away from the connection with the detecting pin 41. These through holes 433 allow the detecting element 42 to transmit light through the groove 4131 of the detecting element 41 to detect whether the connector 2 is a good or defective product. The fourth detecting portion 414 is exposed in the connecting base 4 for contacting the long and short pins of the connector 2.

[0052] Furthermore, the moving member 3 includes a driving member 31, a pushing member 32 and a base 33 that are interconnected. The base 33 is arranged on the base 1, and the driving member 31 and the pushing member 32 are arranged on the base 33. One end of the pushing member 32 is connected to the driving member 31, and the other end is connected to the connecting seat 43. The driving member 31 can drive the pushing member 32 to drive the connecting seat 43 to perform horizontal reciprocating motion relative to the connector 2, so that the detection member 41 connected to the connecting seat 43 abuts against or moves away from the long and short pins 21 of the connector 2.

One end of the pushing member 32 is connected to the driving member 31, and the other end is connected to the connecting seat 43. The driving member 31 can drive the pushing member 32 to drive the connecting seat 43 to perform horizontal reciprocating motion, that is, drive the connecting seat 43 closer to or away from the connector 2, so that the detection member 41 abuts against the long and short pins of the connector 2 to detect whether the connector 2 is a good product.

[0054] The driving member 31 in this embodiment is specifically a detection cylinder.

[0055] Furthermore, the movable member 3 also includes a sliding member 34, one side of the sliding member 34 is set on the base 33, and the other side is connected to the driving member 31, and the sliding member 34 has a sliding groove, and the pushing member 32 is slidingly set in the sliding groove.

The driving member 31 in the movable member 3 drives the detection member 41 and the detection member 42 on the connecting seat 43 to move toward the connector 2, so that the multiple detection members 41 respectively abut each long and short pin in the connector 2, and the detection member 41 with the elastic member 4121 forms a certain compression interference with the long and short pins of the connector 2. When the detection member 41 abuts the long and short pins of the connector 2, the groove 4131 on the detection member 41 can correspond to the position of the detection members 42 on both sides of the detection member 41, and the light of the optical fiber sensor is detected to see whether it can pass through the groove 4131 on the detection member 41.

[0060] Specifically, the optical fiber amplifier 5 begins to determine whether the light from the optical fiber sensor can normally pass through the groove 4131 on the detection component 41. If it can pass through normally, it proves that the height consistency of the connector 2 is OK, that is, the connector 2 is a good product; if the light from the optical fiber sensor cannot pass through the groove 4131, or the light is blocked by the groove 4131, it means that the connector 2 is a defective product.
