Description

connector terminal

technical field

The utility model relates to a connector terminal, in particular to a connector terminal which is arranged in a socket connector of a CPU (Central Processing Unit) to be butted with pins of the CPU.

Background technique

The socket connector provided on the circuit board is usually used to accommodate electronic components, so that the electronic components can be electrically connected to the circuit board. When electronic components, such as electronic components with grid array pins, are to be inserted into receptacle connectors, it is necessary to achieve zero insertion force.

In the prior art, the terminals provided on the socket connector for docking with the pins of the electronic components can be divided into two types. The other type is a single-piece structure, which clamps the pins with the assistance of one side wall of the terminal receiving hole, thereby achieving electrical connection between the terminals and the pins. and the purpose of mechanical cooperation. It can be known from the above prior art that the single-piece structure terminal occupies less space than the two-piece structure terminal, so the terminal density on the socket connector can be increased, which is in line with the high-speed and high-frequency signal transmission currently required. However, since the single-piece terminal only clamps the pins by the clamping force generated by the assistance of one side wall of the terminal receiving hole, and the elasticity of the terminal is insufficient, it will inevitably lead to insufficient contact force between the terminal and the pin, which will affect the two conductivity between.

Therefore, it is necessary to find a new structure to replace the existing structure.

Utility model content

The embodiment of the present invention provides a connector terminal with enhanced holding force.

The utility model provides a connector terminal, which comprises a contact portion, a neck portion located below the contact portion, a holding portion located below the neck portion, and end feet located below the holding portion, wherein opposite sides of the end feet are provided with a plurality of outwardly protruding protrusions.

The utility model provides a connector terminal. The width of the neck portion in the horizontal direction is narrower than the width of the contact portion and the holding portion in the horizontal direction, and the contact portion has a certain elasticity relative to the holding portion. A plurality of barbs are arranged on opposite sides of the holding portion, the width of the barb located at the bottom gradually decreases upward in the horizontal direction, and the width of the barb located at the top is the narrowest in the horizontal direction. The end feet extend downward integrally from the middle of the holding portion, and are roughly rectangular parallelepipeds with narrower widths. The shape of the protrusion is a cylinder, and may also be other shapes of a cone or a triangle.

The utility model provides a connector terminal. The opposite sides of the end feet are provided with a plurality of protrusions protruding outward, and the protrusions can increase the stable contact with the terminal accommodating holes and increase the holding effect.

Description of drawings

In order to illustrate the embodiments of the present invention or the technical solutions in the prior art more clearly, the following briefly introduces the accompanying drawings used in the description of the embodiments or the prior art. Obviously, the accompanying drawings in the following description The drawings are some embodiments of the present invention. For those of ordinary skill in the art, other drawings can also be obtained from these drawings without creative labor.

FIG. 1 is a schematic structural diagram of a connector terminal of the present invention.

Detailed ways

The utility model specifically discloses a connector terminal 10 , and the connector terminal 10 is punched from a metal material. The connector terminal 10 includes a contact portion 12 in a sheet-like structure, a neck portion 14 positioned below the contact portion 12 , a holding portion 16 positioned below the neck portion 14 , and a pin 19 positioned below the holding portion 16 .

The width of the neck 14 in the horizontal direction is narrower than the width of the contact portion 12 and the holding portion 16 in the horizontal direction, so that the contact portion 12 has a certain elasticity relative to the holding portion 16 and can be displaced and twisted. Several barbs 18 are disposed on opposite sides of the holding portion 16 , wherein the horizontal width of the lowermost barb 18 gradually decreases upward, and the uppermost barb 18 has the narrowest horizontal width. The barbs 18 can fix the terminal 10 in the terminal receiving hole (not shown) of the socket connector base (not shown). The pin 19 extends downward integrally from the middle of the holding portion 16 , and is roughly a narrow rectangular parallelepiped. The bottom of the terminal accommodating hole passing through the base is electrically connected to the circuit board (not shown). The opposite sides of the end feet 19 are provided with a number of protrusions 17 protruding outward. The stable contact between the connector terminal 10 and the terminal receiving hole is increased.

The plurality of barbs 18 of the connector terminal 10 described in this case can increase the stable contact with the terminal receiving hole, and the protrusions 17 of the terminal feet 19 can increase the stable holding effect with the terminal receiving hole.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, but not to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that : it can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements to some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the various embodiments of the present utility model Scope of technical solutions.
