Description

[Technical field]

[0001] The present invention relates to the technical field of a connector, and in particular to a high-frequency connector applied in high-frequency signal transmission and having an automatic locking structure. [Background technology]

[0002] The traditional wire-to-board connector is a connection component that electrically connects the wire to the circuit board. Its advantage is that it does not need to be soldered to the circuit board through physical welding, allowing users to easily achieve the function of electrical connection by plugging and unplugging.

[0003] In order to ensure that the connector and the wire can be in stable contact, various connection methods have been developed, such as the automatic latching method, which allows the connector and the wire to be easily connected without falling off, and the aforementioned action will automatically latch during the process of inserting the wire into the connector to maintain the connection between the connector and the wire; however, the traditional connector with automatic latching has a relatively complex automatic latching structure, resulting in a relatively thick overall thickness, and is not suitable for use in thin application fields.

[0004] Furthermore, conventional connectors have the disadvantage of being unable to effectively perform high-speed transmission due to interference from signals such as electromagnetic waves.

[0005] In view of this, the present invention provides a high-frequency connector with an automatic locking structure, which is used to solve the defects caused by the traditional connector. [Summary of the invention]

[0006] The first object of the present invention is to provide a high-frequency connector with an automatic locking structure, which can be used in the application field of high-frequency signal transmission and can automatically lock the flat wire in the connector and release the flat wire from the connector by applying external force.

[0007] The second purpose of the present invention is to provide a shell having a first elastic member, a second elastic member and a shell grounded according to the aforementioned high-frequency connector with an automatic locking structure, so that the grounding layer of the flat conductor can be connected to the grounding wire of the circuit board through the first elastic member, the second elastic member and the shell grounding.

[0008] The third object of the present invention is to provide a housing, a rubber core, a cover body and a locking assembly according to the aforementioned high-frequency connector with an automatic locking structure, and to lock the flat wire in the accommodating space by arranging the locking assembly on the cover body.

[0009] A fourth object of the present invention is to achieve the purpose of locking and unlocking the flat conductor by adjusting the angle of the rotating shaft block of the cover acting on the groove of the shell based on the high-frequency connector with automatic locking structure mentioned above.

[0010] A fifth objective of the present invention is to provide a first latch and a second latch according to the aforementioned high frequency connector with an automatic locking structure, so as to fix the cover to the rubber core.

[0011] A sixth objective of the present invention is to provide a stopper structure on the housing and the rubber core according to the aforementioned high-frequency connector with an automatic locking structure, so as to fix the rubber core in the first accommodation space of the housing.

[0012] The seventh object of the present invention is that according to the aforementioned high-frequency connector with an automatic locking structure, the groove body and the shaft protrusion form an interference structure, and the interference structure is used to determine the rotation range of the angle, so that the cover body is restricted from flipping within a specific angle range, and the flipping of the cover body will not squeeze the flat wire.

[0013] To achieve the above and other purposes, the present invention provides a high-frequency connector with an automatic locking structure. The high-frequency connector with an automatic locking structure can connect a flat wire and a circuit board. The flat wire at least includes a conductive layer, a first grounding layer, a second grounding layer and an insulating layer. The conductive layer is arranged between the first grounding layer and the second grounding layer, and the insulating layer covers the conductive layer, the first grounding layer and the second grounding layer, and a head end is formed at the front edge of the flat wire and notches are formed on two sides of the head end. The head end exposes the first grounding layer and the second grounding layer. The high-frequency connector with an automatic locking structure includes a shell, a rubber core, a cover, a locking assembly and a terminal. The shell forms a first accommodating space, an insertion port, a first elastic member, a second elastic member, an insertion port and a shell grounding. The first accommodating space is connected to the insertion port. The first elastic member and the second elastic member are respectively formed on two side surfaces of the shell. The first elastic member can contact the first grounding layer and the second elastic member can contact the second grounding layer. The shell grounding can connect the grounding wire of the circuit board. The rubber core is arranged in the first accommodating space. The rubber core forms a second accommodating space, a first snap-on component, a groove body, a first notch and a second notch. The second accommodating space is connected to the insertion port for accommodating the head end. The first notch is arranged corresponding to the second elastic component and the second notch is adjacent to the first snap-on component. The cover body includes an axial protrusion, an opening and a second snap-on component. The axial protrusion is arranged corresponding to the groove body, and the second snap-on component is arranged corresponding to the first snap-on component. The locking assembly is arranged on the cover body. The locking assembly includes a fixing portion, an elastic arm and a locking protrusion. The elastic arm is arranged between the fixing portion and the locking protrusion, and the elastic arm is arranged corresponding to the opening. The locking protrusion is arranged corresponding to the notch of the head end and the fixing portion is arranged on the rubber core. The terminal is arranged in the second accommodating space to be able to electrically connect the conductive layer. Among them, the axial protrusion of the cover body is combined with the groove body of the rubber core, so that the cover body and the rubber core are clamped at an angle. When the angle approaches 0 degrees, the first snap fastener and the second snap fastener engage with each other, and after the flat wire enters the second accommodating space from the insertion port, the first elastic member can contact the first grounding layer and the second elastic member can contact the second grounding layer, so that the first grounding layer is connected to the grounding wire of the circuit board through the first elastic member and the shell grounding, and the second grounding layer is connected to the grounding wire of the circuit board through the second elastic member and the shell grounding.

[0014] Compared to the prior art, the present invention provides a high-frequency connector with an automatic locking structure that can be used as a thin connector, and in particular, can provide a shell to connect the ground layer of the flat conductor to the ground wire of the circuit board, so that the connector can be used in the application field of high-frequency signal transmission.
