Detailed Description
The following detailed description of the present invention will be made with reference to the accompanying drawings so as to facilitate the understanding of the present invention by those skilled in the art. It should be understood that the embodiments described below are only some embodiments of the invention, and not all embodiments. All other embodiments obtained by a person skilled in the art without any inventive step, without departing from the spirit and scope of the present invention as defined and defined by the appended claims, fall within the scope of protection of the invention.
As shown in fig. 1 and 2, the straight connector socket includes a first base 1 having a pin through hole formed therein, a pin 2 mounted on the pin through hole, and a gap 5 formed between the pin 2 and an inner wall of one end of the pin through hole near a bottom surface of the first base 1.
As shown in fig. 2, the first base 1 and the pin 2 are in interference fit. In order to ensure the stability of the first base 1 and achieve good heat dissipation, as shown in fig. 2, the cross section of the pin through hole near the bottom surface of the first base 1 is isosceles trapezoid (that is, the bottom surface of the first base 1 is provided with a trapezoid groove communicated with the pin through hole to form a final pin through hole). Wherein, an interior angle of the isosceles trapezoid is 45 degrees.
In order to match the pins 2 with different sizes and ensure the stability of the whole straight connector socket, the cross section of each pin 2 is rectangular or circular, the side length or the diameter of each pin 2 is b, the lower bottom of the isosceles trapezoid is a, and a is more than or equal to 3 b. When the thickness of the first base 1 leaning on the pick-up pin perforation is 1.6-2 mm, the height of the isosceles trapezoid is 0.8-1 mm, so that good heat dissipation is realized, and the stability of the straight connector socket is ensured.
As shown in fig. 2 to 4, the edge of the first base 1 has an arcuate section extending upwardly and cooperating with a step 61 on the top edge of the second base 6 in the plug. Based on the cooperation of the arc-shaped section and the step 61, the detachable connection (plugging locking and separation) of the plug and the straight connector socket is completed.
When the pins 2 are multiple and distributed in an array, all the trapezoidal grooves in the same row or the same column are communicated, so that good heat dissipation is formed. In the second embodiment, the bottom surface of the first base 1 is provided with a rectangular groove communicated with the pin through hole to form a final pin through hole.
In a second aspect, a connector is provided that includes a plug and a straight connector receptacle of the present design.
In implementation, as shown in fig. 4 to 6, the edge of the first base 1 has an arc-shaped section which extends upwards and is matched with the step 61 on the top edge of the second base 6 in the plug, the side wall of the second base 6 is provided with a limiting hole 62, the second base 6 is provided with a spring plate, one end of the spring plate is provided with a clamping part 72 for installing the lead 8, the other end of the spring plate is provided with a bending section matched with the contact pin, the bending section is provided with a first limiting bulge 73 matched with the limiting hole 62, one surface of the bending section, which is far away from the limiting hole 62, is provided with two second limiting bulges 71 which are symmetrically distributed, and a channel for the contact pin 2 to pass through is formed between the two second limiting.
When the pin 2 in the socket is inserted into the plug, the pin 2 applies positive pressure to enable the spring leaf to be pressed transversely, and then the elastic reaction force of the spring leaf enables the pin 2 to keep balance and stability and the contact is reliable. The spring plate is installed based on the matching of the limiting hole 62 and the first limiting bulge 73, and the contact between the pin 2 and the spring plate is more tight due to the arrangement of the two second limiting bulges 71, so that the electric connection stability of the connector is improved. In application, the exposed end of the lead wire 8 is usually crimped to the engaging portion 72 by a crimping tool.
In a third aspect, as shown in fig. 7, a circuit board is provided, which includes a first body 3 (i.e., a printed circuit board), and a straight connector socket designed according to the present scheme is soldered on the first body 3. Wherein the welding point 4 is located on one side of the first body 3 away from the first base 1.
The fourth aspect provides an electronic product, which comprises a second body, wherein the second body is provided with a circuit board designed by the scheme.
