Description

Golden finger self-locking type debugging interface device for vehicle-mounted entertainment system

Technical Field

The utility model relates to a vehicle-mounted entertainment system debugging interface technical field especially relates to a golden finger is from locking-type vehicle-mounted entertainment system debugging interface arrangement.

Background

At present, car navigation stereo set, display, instrument MCU and SOC debugging burn interface, general host computer adopt debugging socket, wiring test point, magnetism to inhale three kinds of modes, and above-mentioned three kinds of modes all have the weak point:

the adoption of the debugging socket mode increases the cost of the product, and the connection flat cable loss is large because the flat cable connection is easy to damage when in use;

manual wiring is wasted by adopting a wiring mode, and a machine is easily damaged;

the magnetic attraction mode is easy to fix unstably in the using process to cause poor contact, inconvenient operation and the like;

meanwhile, a large window needs to be reserved on the host shell in all the three modes, and the requirements on product interface information safety cannot be met in terms of product appearance and safety.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a technical problem how to guarantee that debugging interface connection is stable, convenient operation and do not have great window in product appearance.

For solving the technical problem, the utility model discloses a technical scheme be a golden finger is from locking-type vehicle-mounted entertainment system debugging interface arrangement, including lock post support, PCB keysets and shell, lock post support hasp is in on the shell, the PCB keysets is fixed on the lock post support, the PCB keysets is equipped with thimble, socket and elasticity locking lever, the thimble is established PCB keysets central authorities, the socket is established by the thimble, the elasticity locking lever is followed PCB keysets periphery distributes and stretches out one end, through the elasticity locking lever is adjusted the thimble is connected, is fixed a position, locking function with the distance of being surveyed the golden finger on the PCB board and realization contact.

The lock cylinder bracket is used for fixing the self-locking debugging device and the shell of a tested product, is made of elastic materials such as steel sheets, can ensure that the adjustment has certain return force, and is convenient to assemble and disassemble;

and sawtooth or semicircular inserting notches are formed in two ends of the lock cylinder bracket and are used for inserting and fixing the PCB adapter plate.

Further, at least one of the sawtooth or semicircular slot openings is flexibly selected according to different distances between the PCB and the shell of different products.

The ejector pin can be a built-in spring type ejector pin or an ejector pin without a built-in spring type ejector pin, and the ejector pin head of the ejector pin is conical.

Preferably, the thimble is sleeved with an insulating tube.

And the shell is provided with a heat dissipation through hole matched with the thimble so that the thimble can be conveniently conducted through the contact with the golden finger on the PCB to be tested.

The lock cylinder support is characterized in that the shell is also provided with a lock hole, and the lock hole is matched with a lock catch arranged on the lock cylinder support in size.

Compared with the prior art, the utility model discloses a debugging interface connection is stable, and convenient operation just does not have great window in product appearance.
