Description
Technical Field

Background
The connector generally consists of a plug and a socket, both of which are composed of a plastic body and conductive terminals held on the plastic body, wherein the plastic body mainly plays a role in insulating and positioning the conductive terminals, and the conductive terminals mainly play a role in conduction. Conventionally, the spring arm for improving the holding force is added to the conductive terminal of the existing connector, and the conductive terminal with the spring arm structure is usually assembled and positioned by directly inserting into a terminal cavity of the plastic body. While the terminal cavities are generally designed to match the shape of the conductive terminal body because they are used to position the conductive terminals. Therefore, in the process of inserting the conductive terminal with the spring arm structure into the terminal cavity, the spring arm usually needs to be subjected to the problem that the surface area is reduced, if the yield is too large, the strength attenuation of the spring piece is obvious, and the contact stability of the connector is poor.
Therefore, in order to solve the above-mentioned problems, it is necessary to design a terminal fitting structure applied to a connector, in view of the shortcomings of the prior art.

in the assembled state, the terminal is inserted in the terminal cavity, the TPA is inserted in the locking cavity, and the jacking part is at least partially inserted in the terminal cavity and jacks up the terminal so that the elastic contact part at least partially extends out of the window.
The preferable technical scheme is as follows: the elastic contact part is formed by extending and bending the front end of the terminal to form a triangular spring plate structure protruding upwards.
The preferable technical scheme is as follows: the wiring portion is composed of at least one group of riveting wings.
The preferable technical scheme is as follows: and anti-skid patterns are arranged on the inner sides of the riveting wings.
The preferable technical scheme is as follows: the buckling part is formed by punching and bending the side walls at the left side and the right side of the terminal to form an elastic sheet structure protruding outwards.
Due to the application of the technical scheme, the utility model has the following beneficial effects:
according to the terminal assembly structure applied to the connector, the limit of the terminal in the front-back direction in the insulating rubber core is realized through the clamping part arranged on the terminal and the clamping groove part arranged in the terminal cavity, and the limit of the terminal in the upper-lower direction in the insulating rubber core is realized through the jacking part arranged on the TPA; the structure can avoid the influence on the connection stability of the connector caused by the fact that the elastic contact part on the terminal is reduced in the assembly process.

Further advantages and effects of the present utility model will become apparent to those skilled in the art from the disclosure of the present utility model, which is described by the following specific examples.
Please refer to fig. 1-5. It should be noted that, in the description of the present utility model, it should be noted that, directions or positional relationships indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., are directions or positional relationships based on those shown in the drawings, or directions or positional relationships in which the inventive product is conventionally put in use, are merely for convenience of describing the present utility model and for simplifying the description, and are not indicative or implying that the apparatus or element to be referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," "third," and the like are used merely to distinguish between descriptions and should not be construed as indicating or implying relative importance. The terms "horizontal," "vertical," "overhang," and the like do not denote that the component is required to be absolutely horizontal or overhang, but may be slightly inclined. As "horizontal" merely means that its direction is more horizontal than "vertical", and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.
In the description of the present utility model, it should also be noted that, unless explicitly specified and limited otherwise, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, integrally connected, mechanically connected, electrically connected, directly connected, indirectly connected through an intermediary, or communicating between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
Examples:
