Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board connectors, and in particular relates to a circuit board connector capable of real-time monitoring of a vibration loosening state. Background Art

[0002] The plug-in matching of the wired pin head and the connector is a common circuit board connection method, in which the connector is fixedly installed on the circuit board, and the wired pin head is plugged into the connector installed on the circuit board to connect with other electronic modules. The wired pin head and the connector can be completely separated, and a stable connection can be achieved after plugging when needed. When the circuit board is used on a vibration device, in order to improve the welding and fixing strength of the connector pin pin and its pin pin, the pin pin is usually set to an 80°-90° bending structure to increase the welding fixing area and make its welding fixing strength higher. However, the circuit board is affected by the vibration force during long-term use, and the bolts used to fix the connector are prone to loosening. If the loose connector is not discovered in time for timely tightening and maintenance, the solder joints between the pin pin and the circuit board will fall off, affecting the service life of the connector and the wired pin head. In addition, under the operation of vibration force, when the plug-in and matching bite force of the wired pin head and the connector is poor, the wired pin head and the connector are also prone to loosening. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a connector with a stable structure that cooperates with a wired pin head, and can detect whether there is a loose gap between the connector and the line and send a feedback signal in time to perform bolt tightening maintenance.

[0009] Compared with the prior art, the advantages of the utility model are as follows: the connector can improve the installation accuracy of the plug-in cooperation between the wired pin head and the connector by setting a first guide slot, a first positioning slot, a first positioning shoulder, and a second positioning slot, while increasing the contact area between the wired pin head and the connector to improve the bite force and avoid the problem of loosening during use. Each pin pin is separately arranged corresponding to the pin hole. Even if the pin pin is displaced due to vibration force, it can be insulated and isolated by the partitions between the pin holes, thereby improving the stability of the wired pin head and the connector during use.

[0017] The two sides of the positioning sleeve 10 are integrally formed with semi-cylindrical anti-rotation protrusions 12, and the mounting hole of the mounting seat of the wire plate is provided with a slot matching the anti-rotation protrusion 12, and the anti-rotation protrusion 12 is embedded in the slot to facilitate installation and positioning.

[0018] A triangular positioning groove 8 is provided on the right side of the top of the connector housing 1. The triangular positioning groove 8 has a correction function. After the pin head is plugged and installed on the connector housing 1, the triangular positioning protrusion inside it is completely embedded in the triangular positioning groove 8, and there is no lateral installation offset problem between the pin head and the connector housing 1.

When the control module detects that the first metal column 16 and the second metal column 17 form a path and the electrical signal of the path is unstable or disappears, it means that a gap appears between the connector housing 1 and the circuit board, and the spring 18 pushes the feedback pin 13 to move downward. The first metal column 16 and the second metal column 17 are in a disconnected state, and the maintenance personnel tighten the bolts for maintenance.
