Description

Technical Field

[0001] This utility model relates to the field of electronic connector technology, and in particular to an assembly structure for connectors. Background Technology

[0002] Connectors, as crucial electrical connection components in electronic devices, are widely used in various circuit systems to transmit electrical signals or power. As electronic devices evolve towards higher integration, miniaturization, and functional diversification, connector design needs to meet higher requirements for terminal density and connection stability. Especially in connections between circuit boards, connectors with higher pin counts are often required to enable multi-channel electrical signal transmission.

[0003] In the prior art, in order to achieve high pin count connections, the metal shell of the connector is usually extended as a single piece. The extended metal shell requires the use of large stamping equipment and molds for processing, which makes the production process complex. In addition, the metal shell is prone to warping and deformation, which affects the assembly accuracy and product qualification rate. Utility Model Content

[0004] The purpose of this application is to provide an assembly structure for connectors to solve the problem that it is difficult to achieve high pin count connections in existing connectors.

[0005] To achieve this objective, the following technical solution is adopted in this application:

[0006] This application provides an assembly structure for connectors, which includes a connecting component and several insulating bodies, wherein:

The connecting assembly includes a first metal shell, a third metal shell, and at least one second metal shell. Each metal shell is fixedly connected to an insulating body to form a single connector. The second metal shell is located between the first metal shell and the third metal shell along a first direction. The first end of the first metal shell and the second end of the second metal shell are each provided with at least one screw hole. The second end of the first metal shell and the first end of the second metal shell are each provided with at least one half screw hole. The opening of the half screw hole faces the second metal shell.

[0008] At least one semi-locking screw hole is opened at each end of the second metal housing along the first direction. The opening of the semi-locking screw hole of the second metal housing faces outward along the first direction. Adjacent semi-locking screw holes along the first direction are joined together to form a complete locking screw hole. The screw passes through the locking screw hole and is tightened on the outer platform to fix the connecting assembly on the outer platform.

[0009] Optionally, the first metal housing and the third metal housing are provided with two screw holes and two semi-screw holes in parallel along the second direction at both ends, and the third metal housing is provided with two semi-screw holes in parallel along the second direction at both ends.

[0010] Optionally, a first limiting surface and a second limiting surface are provided in the screw hole. The first limiting surface is configured to limit the screw in the vertical direction, and the second limiting surface is configured to limit the screw in the circumferential direction.

[0011] Optionally, the connecting component has inwardly protruding and upwardly extending locking blocks on both sides near the bottom, and the upper end of the insulating body has locking slots on both sides that are adapted to the locking blocks.

[0012] Optionally, a positioning block is provided on the bottom surface of the insulating body, and a positioning groove is provided on the outer platform, with the positioning block and the positioning groove being compatible.

[0013] Optionally, the connecting component is located above the insulating body and has a number of positioning holes along the first direction. The insulating body is provided with a contacting plate, and the upper end of the contacting plate is provided with a number of protrusions along the first direction. The number of protrusions are adapted to the number of positioning holes.

[0014] Compared with the prior art, the assembly structure for connectors proposed in this application has the following advantages:

[0015] 1) By interlocking the semi-locking screw holes of adjacent metal shells to form new locking screw holes, screws are tightened into the locking screw holes to fix the connecting components in place. This not only realizes modular assembly of connectors and flexibly expands the number of terminal pins of the connector, but also has a simple structure, is easy to operate, and improves the connection efficiency of the connector.

[0016] 2) By setting multiple screw holes and half screw holes, a multi-point locking structure is provided, which enhances the stability of the connecting components.

[0017] 3) The combination of bumps and positioning holes ensures quick and accurate installation of the metal shell on the insulating body, while improving the grounding effect and meeting the stability and electrical performance requirements of high PIN number connectors.
