Abstract
The utility model relates to a fisheye terminal, include basal portion, crimping portion and participate in the foot portion, the both ends of crimping portion link to each other with basal portion and plug foot portion respectively, this crimping portion is the fisheye form, crimping portion middle part fretwork form the fisheye hole, crimping portion and participate in its bilateral symmetry of one end that the portion links to each other and arrange two archs. The utility model adds a bulge on each side of the end of the crimping part, when the fisheye terminal is pressed into the circuit board, the bulges on each side of the crimping part just prop against the circuit board to prevent the circuit board from falling off; the side wall of each bulge close to one side of the base part is an inwards-concave surface, and the concave surface enables the bulge to be in a hook shape, so that the bulge can better abut against the circuit board; the fisheye hole end has a semicircle orifice, and the semicircle orifice is located between two archs, and when the fisheye terminal impresses the circuit board, the arch of both sides receives the extrusion and takes place elastic contraction more easily.
Description
Technical Field
The utility model relates to a connector connecting piece technical field especially relates to a fisheye terminal.
Background
The fisheye terminal is widely applied to communication connectors or electric connectors and circuit boards, generally has a determined specification, has a determined thickness, cannot be changed randomly, and is generally inserted into a welding hole of a printed circuit board. The fisheye terminal generally has large elastic force, but is easy to fall off after long-time assembly, and when the cross section of a crimping part of the fisheye terminal is deflected, the fisheye terminal is easy to elastically contract under extrusion, so that the fisheye terminal is easy to withdraw from a welding hole after being inserted, and the open circuit condition is caused.
Disclosure of Invention
The utility model aims to solve the technical problem that a fisheye terminal is provided, can prevent effectively that it from withdrawing from leading in the welding hole easily, guarantee to be connected reliably with the circuit board.
The utility model provides a technical scheme that its technical problem adopted is: the fisheye terminal comprises a base, a crimping part and a pin part, wherein two ends of the crimping part are respectively connected with the base and the pin part, the crimping part is fisheye-shaped, the middle of the crimping part is hollowed to form a fisheye hole, and two bulges are symmetrically arranged on two sides of one end, connected with the pin part, of the crimping part.
As a supplement to the technical solution of the present invention, the base portion, the crimping portion, and the pin portion are integrally formed.
As right technical scheme a supplement, the one end that the fisheye hole is close to the pin portion be provided with the semicircle orifice, this semicircle orifice is located between two archs.
As a supplement to the technical solution of the present invention, the base is in a long strip shape.
As a supplement to the technical scheme of the utility model, every protruding lateral wall that is close to basal portion one side is inside sunken concave surface.
As a supplement to the technical proposal of the utility model, the fish eye hole is in the shape of a rugby.
Has the advantages that: the utility model relates to a fisheye terminal, wherein, two sides of the end part of a crimping part are respectively added with a bulge, when the fisheye terminal is pressed into a circuit board, the bulges at the two sides of the crimping part just prop against the circuit board, so as to prevent the circuit board from falling off; the side wall of each bulge close to one side of the base part is an inwards-concave surface, and the concave surface enables the bulge to be in a hook shape, so that the bulge can better abut against the circuit board; the fisheye hole end has a semicircle orifice, and the semicircle orifice is located between two archs, and when the fisheye terminal impresses the circuit board, the arch of both sides receives the extrusion and takes place elastic contraction more easily.

Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a front view of the present invention;
fig. 3 is a partially enlarged view of fig. 2A according to the present invention.
The figure is as follows: 1. base, 2, crimping portion, 3, pin portion, 4, eyelet, 5, bulge, 6, concave surface, 7, semicircle orifice.
Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
The utility model discloses an embodiment relates to a fisheye terminal, as shown in fig. 1-3, including basal portion 1, crimping portion 2 and participate in portion 3, crimping portion 2 both ends link to each other with basal portion 1 and plug foot portion 3 respectively, this crimping portion 2 is the fisheye form, crimping portion 2 middle part fretwork form fisheye hole 4, crimping portion 2 and participate in its bilateral symmetry of the continuous one end of portion 3 and arrange two archs 5. The utility model adds a bulge 5 on each side of the end of the crimping part 2, when the fisheye terminal is pressed into the circuit board, the bulges 5 on each side of the crimping part 2 just support the circuit board to prevent the circuit board from falling off; the side wall of each protrusion 5 close to one side of the base part 1 is an inwards concave surface 6, and the concave surface 6 enables the protrusion 5 to be in a hook shape and to better abut against a circuit board.
One end of the fisheye hole 4 close to the pin part 3 is provided with a semicircular hole 7, and the semicircular hole 7 is positioned between the two bulges 5. The end of the fish eye hole 4 is provided with a semicircular hole 7, the semicircular hole 7 is positioned between the two bulges 5, and when the fish eye terminal is pressed into the circuit board, the bulges 5 at the two sides are extruded to be more easily elastically contracted.
The base part 1, the crimping part 2 and the pin part 3 are integrally formed, so that the connection strength and the stability of the three parts are ensured.
The base 1 is long.
The fisheye hole 4 is in a football shape, so that the elastic performance of the crimping part 2 can be effectively enhanced. The middle of the fisheye hole 4 is large, the two ends of the fisheye hole are small, and the width of the fisheye hole 4 is gradually reduced from the middle to the two ends.
