Problems solved by technology

This kind of press-in nut structure, due to the combination of the nut and the plastic body by cold pressing, can withstand limited torsion and tension, so that this structure often fails to meet the requirements for use; in addition, due to different plastic materials, there will be large differences. poor compatibility
It is also possible to integrate the nut into the plastic body of the socket by means of ultrasonic waves after hot melting to increase the torque and pull-out force requirements; although this press-in nut structure can enhance the bonding force between the nut and the plastic body, the processing technology is complicated and the environment loud noise

Embodiment 1

[0033] like figure 2 and image 3 As shown, an improved structure of a push-in nut for a plug-in electrical connector, including a plastic body 11 of a plug-in electrical connector socket 1, and a plastic body 11 is formed on the surface where the plastic body and the plug 2 of the plug-in electrical connector are docked. The slot hole 12 having at least two straight planes A121 also includes a press-in nut 13 correspondingly pressed into the slot hole, and the press-in nut has a straight plane B131 corresponding to the straight plane A of the slot hole, Protrusions 132 are formed on the straight plane B of the press-in nut, undercuts 122 corresponding to the protrusions are formed on the straight plane A of the slot hole, and the press-in nut is pressed into the slot with interference Among them, the straight plane A fits with the straight plane B, and the convex point buckles with the undercut. In this way, by changing the traditional circular nut structure into a polygon...

Embodiment 2

[0038] see Figure 5 and Image 6 The difference between this embodiment 2 and embodiment 1 is that a soldering pin 133 is connected to the bottom of the press-in nut, and a via hole 124 corresponding to the soldering pin is formed at the bottom of the slot, and the soldering pin tightly fits through the vias. Preferably, the press-in nut is integrally formed with the welding pin. In this way, the welding pins can be welded together on the PCB when the product (plug-in electrical connector socket) is welded, so that the press-in nut is integrated with the PCB, thereby increasing the torque and pulling force.

[0039] The application of the plug-in electrical connector with the improved structure of the press-in nut in Embodiment 1 can be found in Figure 7 shown.

Abstract

The invention discloses a press-in nut improved structure of a plugging type electric connector. The press-in nut improved structure of the plugging type electric connector comprises a plastic body of a plugging type electric connector plug, wherein a slot hole with at least two straight planes A is formed on a butted plane of the plastic body and the plugging type electric connector plug; the press-in nut improved structure also comprises a press-in nut correspondingly pressed in the slot hole; the press-in nut has straight planes B corresponding to the straight planes A of the slot hole; convex points are formed on the straight planes B of the press-in nut while inversing buckles corresponding to the convex points are formed on the straight planes A of the slot hole; the press-in nut is pressed into the slot hole in an interference manner; the straight planes A and the straight planes B are fitted with each other; and the convex points are buckled with the corresponding inversing buckles. The press-in nut improved structure of the plugging type electric connector can bear relatively high torsion force, and can bear relatively high pulling-out force in a pulling-out direction, so that that press-in nut improved structure is applicable to various different plastic materials.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to an improved structure of a push-in nut for a plug-in electrical connector. Background technique [0002] The plug-in electrical connector is mainly composed of a plug and a socket. The plug and the socket are docked, and a nut is pressed into the face of the socket and the plug, and a screw is provided on the corresponding nut position on the plug. Tightly fit into the nut to increase the firmness of the combination of the plug and the socket. However, in the prior art, the nut is usually pressed into the plastic body of the socket by cold pressing, and the interference fit between the embossing of the nut and the plastic body is used to meet the locking torque and pull-out force requirements. This kind of press-in nut structure, due to the combination of the nut and the plastic body by cold pressing, can withstand limited torsion and tension, so that this structure often fa...
