Magnetic connector for automatic test

Technical Field

The utility model discloses be applied to connector technical field, in particular to a magnetism connector for automizing test.

Background

The magnet type connector is also called a magnetic connector and a magnetic connector, and is widely used as one of connectors on electronic equipment. The connector is mainly used for conveniently communicating two isolated and non-communicated circuits, so that current flows, and the circuits realize preset functions. The magnet connector is used for connecting the two connectors by a magnetic attraction method, and finally information transmission is realized.

There are roughly two types of magnetic connectors currently available: one is that there is no automatic alignment function; the other is that there is the function of automatic alignment, guide pin through this design to the machine precision relatively high, simultaneously to the connector of intensive many test points, the guide pin is in fact to occupy bigger space, and in the long-time use in-process, the guide pin is worn and torn, has metal powder to adhere to in the connector, probably has the potential risk that the connector can short circuit. The above problems can be solved well if a magnetic connector for automated testing can be designed which is simple in structure and saves internal space.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art not enough, provide a simple structure and save the magnetic connector that is used for automatic test of inner space.

The utility model adopts the technical proposal that: the utility model discloses a public head and female head, be provided with the first magnet of a plurality of pieces in the public head, be provided with a plurality of second magnets in the female head, first magnet with second magnet heteropolar looks is inhaled, the bottom of public head is provided with the guide way, works as the guide way with behind the top looks adaptation of female head the effect end of public head with the effect end of female head contacts.

According to the scheme, the male head is arranged on the testing equipment in a floating mode, the female head is fixed on the testing module, when the testing module is sent into the testing equipment, the first magnet and the second magnet attract in opposite poles, the male head is close to the female head rapidly until the guide groove in the male head is matched with the top of the female head, so that alignment and attachment are achieved, and the action end of the male head is in contact with the action end of the female head, so that signal conduction can be achieved. Consequently, with the connector relative ratio that utilizes the locating pin to lead, the utility model is not only simple in structure, moreover guide structure and public head, female first integrated into one piece have saved the inner space greatly.

Further, public head includes first faller subassembly and the first shell of being made by stainless steel material, first faller subassembly sets up in the first shell, the guide way sets up the bottom of first shell, female head includes second faller subassembly and the square shell of being made by non-metallic insulating material, second faller subassembly sets up in the square shell, the guide way with the top looks adaptation of square shell. Therefore, the first shell is made of stainless steel materials, the square shell is made of non-metal insulating materials, and therefore metal powder cannot be attached to the magnetic connector when the first shell and the square shell are matched for a long time, and the problem of short circuit can be avoided.

Further, first faller subassembly includes first faller, first PCBA board and a plurality of first probe, first faller setting is in on the first PCBA board, works as first probe passes vertical setting behind the first faller is in on the first PCBA board, first probe with first PCBA board signal connection. It can be seen that the first probe plate is made of an insulating material for fixing and isolating each of the first probes; the first probe is a spring probe and is used for being in contact with the probe of the female head; the first PCBA board is used for achieving bridging of the first probe and a flexible flat cable, and the flexible flat cable leads out signals of the first PCBA board.

Further, the second faller subassembly includes second faller, second PCBA board and a plurality of second probe, the second faller sets up on the second PCBA board, the second probe passes vertical setting behind the second faller on the second PCBA board, the second probe with second PCBA board signal connection, the bottom of first probe with the top of second probe contacts. It can be seen that the second needle plate is made of an insulating material for fixing and isolating each of the second probes; the tail end of the second probe and the second PCBA board are welded together; the second PCBA board is used for leading the signal of the second probe into a PCBA end.

Further, public head still includes the visor, first shell setting is in on the visor, first PCBA board with be provided with first bubble cotton between the visor. Therefore, the protective cover is made of stainless steel materials and protects the internal structure of the magnetic connector, and the first foam is used for isolating the first PCBA board and the protective cover and preventing short circuit or damage to components on the first PCBA board.

Furthermore, the number of the first magnets and the number of the second magnets are two, the two first magnets are respectively located on two sides of the first needle plate, and the two second magnets are respectively located on two sides of the second needle plate. Therefore, the first magnet and the second magnet both provide attraction force, and the male head and the female head can be conveniently and quickly aligned and attached.

Furthermore, a second foam is arranged between the second magnet and the second needle plate. Therefore, the female head is used in the vibration test jig, the requirement on the consistency among all jigs is high, and therefore when the female head is used for installing the second magnet, the second foam is required to be attached, the second magnet is prevented from shaking in the female head in a clearance mode, and potential influence caused by vibration test can be avoided.
