Description

Connector combination locking structure

The present invention provides a locking structure of a connector assembly, in particular, the plug connector is inserted downwardly into the socket connector, and the buckle portion at the two sides of the body is pushed to be elastically deformed on the fastening elastic piece, and When the buckle of the fastening portion passes over the bottom of the buckle, the elastic buckle of the buckle can be buckled with the buckle to increase the stability of the overall fitting.

Press, the general connector is used in the connection between the electronic signal and the power supply and its accessories, the main function is to provide a connection between various electronic devices or devices, and to ensure that the signal can be accurately transmitted, and the connector with its application products Different from power and environment, it has developed various types and can be widely used in consumer electronic products such as computers, notebook computers, smart phones, or in the fields of household appliances, telecommunications, and communication equipment. And because the current electronic product design tends to be light, thin, short, and small, the connectors inside various electronic products need to be greatly reduced, and the thin connector is bonded to the general wire or flexible circuit board. And fixed will be more difficult.

Furthermore, as the volume of electronic products becomes thinner and thinner, the components of the electronic components mounted on the circuit board need to be more precise and miniaturized, and the overall structural strength needs to be strengthened. General connectors (such as boards) For board connectors, wire-to-board connectors, etc.), a male connector and a female connector are usually used for mating, and the signal or power supply is transparent. The circuit board is transmitted to the control circuit to perform the corresponding operation function. However, when the male end connector is mated with the female end connector, in order to reduce the overall structure height, most of the assembly is performed by fitting, and the male end connector is firstly connected. The body is inserted into the fitting space of the female connector, and the protruding button of the body is fastened in the buckle groove of the base, so that the plurality of conductive terminals of the body can be brought into contact with the corresponding contact on the base. The terminals are electrically connected to realize two parallel-parallel circuit boards, or a flexible circuit board, and an electrical connection between the cable and the circuit board, but the body and the base are integrally formed of a colloid made of resin. When the body and the base are engaged with each other, the manner in which the buckle and the buckle are fastened to each other may cause mutual wear due to multiple plugging and unplugging, and the overall fitting force is reduced, and even excessive assembly is caused by excessive extrusion. The damage caused by colloids or structural damage is the key to redesigning the people in this industry.

Therefore, in view of the above-mentioned problems and shortcomings, the new creators have collected and analyzed relevant materials through various assessments and using the continuous trial and modification of the years of R&D experience in this industry. A new type of patent was born.

The main purpose of the present invention is that the socket connector has a guiding groove longitudinally disposed on the positioning portion at the two sides of the base, and the fixing portion of the fastening elastic piece is positioned in the chamber at the inner wall surface of the guiding groove. The fixing portion is bent outwardly and has an elastic portion and an ejector portion extending into the guiding groove, and each of the pushing portions respectively extends outwardly and has a buckle that first passes over the lower portion of the positioning portion and is re-folded when the plug is connected. When the body of the device is inserted into the base, the contact terminal is electrically contacted with the conductive terminal, and the latching portion at the two sides of the body is pushed by the positioning post on the pushing portion of the buckled elastic piece. The laterally pressing elastic portion is elastically deformed, and the convex buckle at the lower portion of the column to be positioned passes over the bottom of the buckle, and the elastic buckle can be laterally extended into the guide by elastic deformation and resetting process. Inside the groove and the buckle They are fastened to each other, and the buckle portion of the body is restrained by the buckle of the snap-up elastic piece from causing upward disengagement or structural damage, and the plug connector and the socket connector can be stabilized even when the overall height is thinned. The mating butt joints are locked and more stable and reliable in vibration and shock environments.

The secondary purpose of the present invention is that the plug connector is integrally formed with a grounding member on the fastening portion of the body, which not only avoids the fastening force caused by the mutual wear of the material (such as the colloid) when the fastening elastic pieces are engaged with each other. Reduce or easily slip off, etc., and have good structural strength, and at the same time, the buckle and the pushing portion of the buckled elastic piece can respectively resist the buckle and the contact surface of the grounding member, and the welding foot and the circuit board Forming a common grounding circuit, the electromagnetic wave and crosstalk generated by the transmission unit of the plug connector can be guided and transmitted to the circuit board through the grounding member and the snapping elastic piece for grounding release. In turn, the quality of the overall signal transmission is more stable and reliable.

Another purpose of the present invention is that when the user wants to pull the plug connector out of the socket connector, it only needs to be inserted into the guiding groove of the two positioning portions by using the jig, and is pushed laterally to the buckle. After the elastic piece of the elastic piece is attached, the pulling piece is subjected to the pushing action, the interlocking piece can be interlocked to generate the outward yaw displacement, and the buckle to be buckled is separated from the protruding buckle of the holding part, and at this time, the buckle can be pulled Pull up the plug connector and pull out the main body from the base of the socket connector to facilitate quick disassembly.
