Description

Male terminal for connector

Technical Field

The utility model relates to a connector is with public terminal.

Background

Connectors, also called connectors, are devices that connect two active devices for transmitting current or signals, such as signals for connecting a body control unit of a vehicle and an instrument panel, etc., and current transmission. The connector consists of a female end connector and a male end connector which are matched in a plugging mode, and a terminal arranged in a shell of the male end connector is called a male terminal.

The current market-used male terminal is mainly divided into a C-shaped (figure 4-5) structure and a U-shaped (figure 6-7) structure, and has the defect of unstable quality because a gap (the thickness is 0.6mm minus the thicknesses of 0.2mm plus 0.2mm on two sides and a gap of 0.2 mm) is formed in the middle, so that the poor phenomena of uneven middle hollow thickness, unsmooth matching, large insertion and extraction force and the like are easily caused.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a three layer construction's male terminal for connector.

In order to solve the above problem, the utility model discloses a technical scheme include: integrative stamping forming's terminal body, the terminal body has contact pin portion, installation department, line ball portion, its characterized in that: the contact pin part is formed by superposing a bottom layer, a middle layer and a top layer continuously, a smooth-transition conical part is arranged between the contact pin part and the installation part, and a conical part is formed at the top of the contact pin part through stamping.

The male terminal for the connector is characterized in that: the installation department is the square structure that is enclosed by bottom, left surface, right flank, top surface, be equipped with at least one joint portion on the top surface with the draw-in groove joint of right flank.

The male terminal for the connector is characterized in that: the top surface is integrally punched and formed with a buckle.

The male terminal for the connector is characterized in that: the buckle is integrally formed with a positioning bulge in a punching mode.

The male terminal for the connector is characterized in that: the integrative stamping forming of right flank rear end has the enhancement limit, the free end of strengthening the limit laminate in the rear end portion of left surface.

The male terminal for the connector is characterized in that: and the right side surface is provided with an anti-misplug boss extending to be higher than the top surface.

The male terminal for the connector is characterized in that: a group of reinforcing ribs are arranged in the wire pressing portion.

The utility model discloses the public terminal advantage for connector as follows: 1, the three-layer structure is adopted, and the adverse phenomena of uneven middle hollow thickness, unsmooth matching, large insertion and extraction force and the like caused by the thickness of a material being 0.2mm are solved; 2. overall structure is more firm, is connected more stably with the casing.

The invention will be further explained with reference to the drawings in the following description:

Detailed Description

Referring to fig. 1-3, the male terminal for connector of the present invention includes a terminal body 1 formed by integral punching. The terminal body 1 has a pin portion 2, a mounting portion 4, and a wire pressing portion 3. The pin part 2 is formed by overlapping a bottom layer 5, a middle layer 6 and a top layer 7 continuously. A smooth transition taper part 8 is arranged between the needle part 2 and the mounting part 4, and a taper part 9 is formed at the top of the needle part 2 through stamping.

Preferably, the mounting portion 4 has a square structure surrounded by a bottom 19, a left side 10, a right side 15 and a top 11. And the top surface 11 is provided with a clamping part 12 which is clamped with the clamping groove 13 of the right side surface 15. To improve the stability of the mounting portion 4.

Preferably, the top surface 11 is integrally stamped and formed with a buckle 14. The buckle 14 is integrally formed with a positioning protrusion 16 in a punching manner, and the positioning protrusion 16 is matched with a positioning groove in the terminal shell to improve the holding force of the terminal after connection.

Preferably, the rear end of the right side surface 15 is integrally formed with a reinforcing edge 17 in a stamping manner, and the free end of the reinforcing edge 17 is attached to the rear end of the left side surface 10. The retention force with the terminal housing is further increased by the design of the reinforcing rim 17.

Preferably, the right side surface 15 is provided with a misplug prevention protrusion 18 extending higher than the top surface 11. The terminal shell is provided with a slot matched with the terminal shell uniquely so as to prevent error insertion.

Preferably, a set of reinforcing ribs 20 is arranged in the crimping portion 3. The design of the reinforcing rib 20 improves the holding force between the crimping part 3 and the lead.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
