Description

Technical Field

[0001] The utility model relates to the technical field of signal relays, and more specifically to a connector for a phase-sensitive track circuit microelectronic receiver. Background Art

[0002] In the phase-sensitive track circuit, the microelectronic receiver is used for the receiving end of the 25Hz phase-sensitive track circuit. The microelectronic receiver uses a relay socket and plug-in combination connector that is consistent with the original phase-sensitive track relay. The connector is made of stacked sheet-type plugs.

[0003] However, the existing microelectronic receivers of phase-sensitive track circuits use cables to connect the plug contacts to the circuit board, and the electromagnetic radiation between the connecting cables is prone to introduce interference. The connector is assembled and fixed by screws with multiple plugs, and the electrical and mechanical properties are not stable enough. For example, the chip-type installation allows gaps to easily form between the plugs or excessive local force, resulting in unstable signal shielding performance or insulation withstand voltage performance between the chips; the overall mechanical properties of the assembled and fixed connector are poor, and when the connector is plugged into the socket, the plug is prone to loosening, affecting the connector's impact resistance.

[0004] Therefore, how to improve the electrical and mechanical properties of the connector, thereby improving the performance of the phase-sensitive track circuit microelectronic receiver is an urgent problem that technical personnel in this field need to solve. Utility Model Content

[0005] In view of this, the utility model provides a connector for a phase-sensitive track circuit microelectronic receiver, thereby improving the electrical and mechanical properties of the connector.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model discloses a connector for a phase-sensitive track circuit microelectronic receiver. The connector is formed by clamping a connecting piece and a gap-filling piece to obtain a connector body. One or more connecting pieces and gap-filling pieces are provided.

[0008] The connecting piece is composed of a metal terminal and an insulating body, the exposed parts at both ends of the metal terminal form welding pins and plug-in terminals, and the insulating body is provided with grooves and protrusions that match each other on two surfaces parallel to the plane where the metal terminal is located;

[0009] The gap-filling piece and the connecting piece have the same insulating main body structure;

[0010] The welding pins on the connector body are connected to corresponding welding holes on the circuit board of the phase-sensitive track circuit microelectronic receiver by welding;

[0011] The plug-in terminals on the connector body are adapted to the relay socket holes at the receiving end of the phase-sensitive track circuit.

[0012] Furthermore, grooves and protrusions are provided according to the position of the connecting piece in the connector body.

[0013] Furthermore, the insulating body is provided with vias in a direction perpendicular to the plane where the metal terminals are located, and the fixing member passes through the vias on a plurality of the connecting pieces to reinforce the connector body.

[0014] Furthermore, grooves and protrusions are provided according to the position of the gap-filling piece in the connector body.

[0015] Furthermore, the impact strength of the connector body and the circuit board after being fixed is greater than or equal to 1.5KJ / m 2 .

[0016] Furthermore, the insulation resistance between the metal terminals of the connector body is not less than 1000 MΩ.

[0017] Furthermore, it is characterized in that the contact resistance of the plug-in terminal is not greater than 0.03Ω, and the plug-in force is greater than or equal to (180±40)N.

[0018] It can be known from the above technical solutions that compared with the prior art, the utility model discloses a connector for a phase-sensitive track circuit microelectronic receiver. The connector is obtained by snapping together a plurality of connecting pieces and gap-filling pieces, which can be arbitrarily arranged and combined to obtain a modular connector with different pins and different spacings that is compatible with the circuit board and the relay socket, and has good flexibility; at the same time, the connecting piece and the gap-filling piece are snapped together by protrusions and grooves and reinforced by fixings, so the connection is stable and has strong impact resistance; and the connector is connected to the circuit board by welding, which solves the problem of the original connection method using plug-ins and cables, which leads to the introduction of interference by electromagnetic radiation between cables, and at the same time enhances the impact resistance of the connector. The utility model improves the stability of the signal of the phase-sensitive track circuit microelectronic receiver by improving the electrical and mechanical properties of the connector.
