Description

Technical Field

[0001] This invention relates to a junction box connector mating test fixture and a junction box connector mating test device. Background Technology

[0002] In the production process of photovoltaic module junction boxes, the cable section of the junction box needs to be processed. Therefore, it is necessary to solve the compatibility problem between the production equipment and other automated terminal equipment, so as to maximize the cable delivery efficiency of the terminal equipment in fully automatic high-speed mode. The cable section has connectors, which mainly consist of ends, core posts, and clips. It is necessary to test the functionality of the connectors. The existing manual testing methods have problems such as slow production efficiency and complex production processes. Summary of the Invention

[0003] In order to overcome the problems encountered in the existing production process, the purpose of this invention is to provide a junction box connector mating test fixture and junction box connector mating test device with high production and processing efficiency.

[0004] To achieve the above objectives, the present invention provides a junction box connector mating test fixture, comprising a fixture base and a fixture body disposed on the fixture base. A connector conformal port is provided on the front end face of the fixture body. The connector conformal port includes a central hole and snap-fit ​​holes located on both sides of the central hole. A copper lug detection guide post is movably disposed within the central hole. The fixture body is provided with a pair of first sliding grooves extending laterally, located outside the snap-fit ​​holes. A locking tongue is movably installed in each of the first sliding grooves. The locking tongue has a longitudinal through hole with a driving surface inside. The locking tongue elastically extends to the snap-fit ​​hole via a first spring. When the connector is installed into the connector conformal port, the connector snaps... The connector is engaged by the latch in the buckle hole, and the connector core pushes the copper lug detection guide post out of the rear end face of the fixture body within the center hole. The fixture body is provided with a pair of longitudinally extending second slide grooves, which communicate with the first slide groove. An n-shaped push block is movably provided on the fixture body. The upper part of the n-shaped push block is elastically supported on the fixture body by a second spring, and the lower part of the n-shaped push block passes through the through hole on the corresponding latch in the second slide groove. The lower part of the n-shaped push block has a wedge-shaped surface that mates with the drive surface. When the n-shaped push block moves longitudinally downward to push the latch outward, the connector buckle is released to allow the connector to separate from the connector conformal port.

[0005] Preferably, a positioning detection guide post is movably provided inside the fixture body. When the connector is installed to the connector conformal port, the connector pushes the positioning detection guide post to the outside of the rear end face of the fixture body.

[0006] Preferably, the fixture body is movably provided with a plurality of ejector pins distributed around the central hole, the ejector pins extending from the fixture body to the outside of the front end face of the fixture body so that the connector is separated from the connector conformal port.

[0007] Preferably, a guide rod is provided in the second slide groove, and a guide groove extending longitudinally is provided at the lower part of the n-shaped push block, with the guide rod installed in the guide groove.

[0008] According to another aspect of the present invention, a junction box connector mating detection device is provided, including the junction box connector mating detection device as described above.

[0009] Preferably, it includes a stepping rotary disk, wherein a plurality of junction box connector mating test fixtures are arranged at intervals on the circumference of the stepping rotary disk.

[0010] Preferably, it includes a loading station, which includes a loading robotic arm that installs the connector to the connector conformal port.

[0011] Preferably, it includes a detection station, which includes a first distance sensor and a second distance sensor disposed behind the fixture body. The first distance sensor detects the distance by which the copper nose detection guide post extends beyond the rear end face of the fixture body, and the second distance sensor detects the distance by which the position detection guide post extends beyond the rear end face of the fixture body.

[0012] Preferably, it includes a first unloading station, which includes a first unlocking wheel and a first ejector driving device. The first unlocking wheel rotates tangentially to the stepping rotary disk. When the junction box connector mating detection fixture on the stepping rotary disk rotates to the first unloading station, the first unlocking wheel pushes the n-shaped push block downwards longitudinally, and the locking tongue moves outwards to release the connector's latch. The first ejector driving device drives the ejector to extend from inside the fixture body to outside the front end face of the fixture body to separate the connector from the connector conformal port.

[0013] Preferably, a second unloading station is included, which includes a second unlocking wheel and a second ejector driving device. The second unlocking wheel rotates tangentially to the stepping rotary disk. When the junction box connector mating detection fixture on the stepping rotary disk rotates to the second unloading station, the second unlocking wheel pushes the n-shaped push block downwards longitudinally, and the locking tongue moves outwards to release the connector's latch. The second ejector driving device drives the ejector to extend from inside the fixture body to outside the front end face of the fixture body to separate the connector from the connector conformal port.

[0014] Due to the adoption of the above technical solutions, the manufacturing cost of this invention is low. The mechanical structure enables the connector to automatically snap into place after insertion, thereby confirming the dimensions of key parts of the connector and performing the required functions of the connector.
