Embodiment 1

[0044] like figure 1 and figure 2 As shown, the electrical connector includes a housing 11 and a locking member 13 , two locking members 13 are provided, and the two locking members 13 have the same structure and are symmetrically arranged on both sides of the housing 11 .

[0045] Take the mating end of the electrical connector as the front end, such as image 3As shown, the casing 11 is provided with a first cavity 18, a second cavity 19 and a third cavity 21 in sequence from the back to the front. The first cavity 18 and the second cavity 19 are both U-shaped cavities. The third cavity 21 is a rectangular cavity.

[0046] like Figure 4 As shown, the locking member 13 is provided with a holding arm 25, a force arm 24 and a blocking arm 32 in sequence from the back to the front. The locking member 13 is provided with an annular ring for clipping into the terminal member 12 at the position corresponding to the holding arm 25. The snap portion 27 in the snap slot 15 . Th...

Embodiment 2

[0058] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the locking member is provided with a positioning hole between the holding arm and the force-receiving arm, and the housing is provided between the first cavity and the second cavity. There are locating posts matched with the locating holes. In this embodiment, the locking member is provided with a positioning column between the holding arm and the force receiving arm, and the housing is provided with a positioning hole between the first cavity and the second cavity for positioning and matching with the positioning column.

Embodiment 3

[0060] The difference between this embodiment and Embodiment 1 lies in that, in Embodiment 1, the blocking arm includes a plate body and a blocking convex ridge on the inner side of the plate body. In this embodiment, the blocking arm only includes a plate body, and the thickness of the plate body is relatively large.

Abstract

The invention relates to the technical field of connectors, in particular to an electric connector. The electric connector comprises a shell and a locking piece, wherein the shell is provided with a first cavity, a second cavity and a third cavity; the locking piece is provided with a holding arm, a force-bearing arm and a blocking arm, a deformation beam is arranged between the holding arm and the force-bearing arm, and the locking piece is provided with a clamping part; the holding arm is provided with a primary clamping position and a secondary clamping position, the force-bearing arm is inserted into the second cavity, the second cavity is provided with a convex hull, the force-bearing arm is provided with an avoiding groove for avoiding the convex hull, and the blocking arm is located in the third cavity; when the locking piece is in the preassembling position, the fixing arm is located at the primary clamping position, the end of the force bearing arm is matched with the convex hull in a jacking mode so that the deformation beam can elastically deform, and therefore the blocking arm swings towards the interior of the shell so as to block insertion of the oppositely-inserted part, and when the locking piece is in the locking position, the fixing arm is located at the secondary clamping position, and the convex hull enters the avoiding groove. And the deformation beam recovers to enable the blocking arm to swing towards the outside of the shell so as to avoid the plug-in component.

Description

technical field [0001] The present invention relates to the technical field of connectors, in particular to an electrical connector. Background technique [0002] In the electrical connector, TPA (terminal position assurance: terminal position assurance) plays the role of locking the terminal to prevent the terminal from falling out under the action of external force and causing the line to be cut off. For example, the Chinese invention patent application with the application publication number CN113991342A discloses a locking structure, which includes a casing and a locking piece. The terminal assembly part is provided with an annular clamping groove, and the locking piece has a clamping part that is clamped into the annular clamping groove, so as to complete the secondary locking of the terminal assembly part. [0003] After the above-mentioned locking piece is fixed to the housing, it cannot be determined whether the clamping part of the locking piece has been inserted i...
