Problems solved by technology

When the electrical connector of this structure is installed, the collar is easy to be installed incorrectly, resulting in difficulty in inserting the metal pin or failing to achieve the anti-retraction effect; in addition, the barbed structure of the metal pin is determined by the wall thickness of the metal pin itself. The material is punched, and the strength is limited by the wall thickness of the pin itself, so it is difficult to guarantee the anti-retraction effect

Embodiment Construction

[0033] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0034] The pin in the present invention belongs to the metal pin (PIN) of the connector in a broad sense. Because the metal pins of the positive and negative connectors of the electrical connector need to be inserted into each other, the metal pins in the positive connector are often defined as pins, and the metal pins in the negative connector are defined as sockets; conversely It is also available; no matter it is defined as a pin or a socket, both belong to the metal pin (PIN) of the connector in a broad sense.

[0035] In the following embodiments, the preparation process will be described in detail by taking the negative metal pin, which is commonly referred to as the sleeve in this field, as an example. The sleeve in this embodiment is a sleeve with an integrate...

Abstract

According to the preparation process of the integrated electric connector metal contact pin provided by the invention, a mode of first edge covering and then stamping is adopted, the clamping ring sheet is fixed on the contact pin sheet in an edge covering mode, and then stamping and co-curling are performed to form a pipe to form an integrated structure, so that the subsequent assembly steps of the electric connector can be reduced, and the production efficiency is improved. The firm degree of connection between the clamping ring and the metal contact pin is effectively ensured; during installation, the metal pin is inserted into the insulating shell, and the elastic sheet on the retainer ring replaces a barb structure on the original metal pin, so that the retainer ring can be automatically clamped and fixed on a step in the insulating shell, and the problems that the retainer ring is placed incorrectly and falls off, and the retaining effect is poor due to the fact that the thickness of the barb structure is influenced by the wall thickness of the metal pin are effectively solved.

Description

technical field [0001] The invention relates to the technical field of electric connectors, in particular to a preparation process of an integrated electric connector metal pin in the electric connector. Background technique [0002] The electrical connector is an indispensable device in the photovoltaic system. Multiple photovoltaic modules are connected to each other through electrical connectors and cables to form a photovoltaic module array. The branch currents of each photovoltaic module are combined and output a large voltage outward. The current commonly used electrical connectors for photovoltaic modules include positive connectors and negative connectors, and the two ends are respectively connected to fixed cables. Both the positive electrical connector and the negative electrical connector The metal pins of the positive and negative connectors need to be inserted into each other, so the metal pins in the positive connector are often defined as pins, and the metal p...
