Description

Technical Field

[0001] The present invention relates to a connector structure, and particularly to a solderless connector in which terminals can be fixed on a circuit board without soldering. Background Art

[0002] A connector (electrical connector) is a commonly used telecommunications / current conduction component in electronic devices, such as in computer equipment, mobile phones / portable electronic devices, vehicle applications, and even spacecraft fields, with a very wide range of uses. Generally, a connector is generally composed of an insulating body. A plurality of terminal slots are provided in the insulating body for setting a plurality of terminals. Then, by soldering (such as through a wave soldering machine), the plurality of terminals are soldered to predetermined contact points on the circuit board, and the connector can be fixed on the circuit board to conduct telecommunications / current.

[0003] Existing connector technologies are as Figure 1 shown. A connector is fixed on a circuit board 92. The connector has an insulating body 91. The insulating body 92 has a plurality of terminal slots 93 for setting a plurality of terminals 94. The terminal 94 has a lower pin 941 and an upper arm 942. The lower pin 941 can be soldered to a predetermined contact point on the circuit board 92 by a wave soldering machine to fix the connector on the circuit board 92.

[0004] Although the aforementioned existing connector technology can be fixed on the circuit board 92 by soldering, however, there are still its deficiencies. For example, after the lower pin 941 is soldered, it is easy to form uneven or unstable soldering quality, resulting in affecting the high-frequency, high-density, and high-power telecommunications transmission applications of the connector, which is obviously not an ideal design. Moreover, since tin is used for soldering, but the electrical characteristics of tin are not good, it is also necessary to solve this problem. Therefore, how to solve these deficiency problems of the existing connector technology should be an important issue that the industry or people of insight should solve and overcome.

[0005] Therefore, in view of the disadvantages in the use of the existing connector technology and the fact that its structural design is not ideal, the inventor of this case started to research and develop its solution, hoping to develop a solderless connector with better high-frequency, high-density, and high-power telecommunications transmission effects of the connector to promote the development of this industry. After much thought, the present invention was born. Summary of the Invention

[0031] The connector 20 has an insulating body. A plurality of positioning posts 21 and a plurality of fixing parts 22 are distributed in appropriate areas of the connector 20 (insulating body), and a plurality of terminal slots 23 are arranged in the connector 20 (insulating body), and the plurality of terminal slots 23 are used to arrange a plurality of terminals 40.

[0032] A plurality of positioning holes 31 and a plurality of fixing parts 32 are distributed in appropriate areas of the gasket connection board (pressing part) 30, and a plurality of conductive connection parts 33 are arranged on the gasket connection board 30. Among them, the plurality of positioning posts 21 of the connector 20 (insulating body) are arranged corresponding to the plurality of positioning holes 11 and 31, and can be combined with each other. And the plurality of fixing parts 12, 22 and 32 are arranged correspondingly, and the gasket connection board 30, the connector 20 and the circuit board 10 can be fixedly connected in sequence through a screw 34 (see Figure 3 ). In appropriate embodiments, the plurality of fixing parts 12, 22 and 32 can also be fixedly connected to each other by a snap group (not shown) for the gasket connection board 30, the connector 20 and the circuit board 10. In this way, the gasket connection board 30 serves as a pressing part to press and consolidate the connector 20 and the circuit board 10 to complete electrical conduction, and its operation is carried out through the electrical conduction between the gasket connection board 30 and the connector 20.

[0033] Please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 as well. The terminal grooves 23 of the connector 20 (insulating body) have engaging grooves 231 on both sides of the front end and terminal upper receiving grooves 232 and terminal lower receiving grooves 233 on the upper and lower surfaces of the front end. The terminal 40 includes a terminal plate 41. At the upper and lower ends of the central portion of the terminal plate 41, a first connecting arm 43 and a second connecting arm 44 are respectively bent toward one side. On both sides of the first connecting arm 43 of the terminal plate 41, an engaging plate 42 is respectively formed. There is a notch 421 between the two engaging plates 42. In other words, the downward (one side) bending of the first connecting arm 43 has the starting distance of the notch 421, while the upward (one side) bending of the second connecting arm 44 does not have the starting distance such as the notch 421, but it is not limited thereto. The downward (one side) bending of the first connecting arm 43 is connected to a first inner arm portion 431, a first bending portion 432, a first outer arm portion 433 and a first end portion 434 at the end; the upward (one side) bending of the second connecting arm 44 is connected to a second inner arm portion 441, a second bending portion 442, a second outer arm portion 443 and a second end portion 444 at the end. Through the elastic structure design of the second connecting arm 44, the second connecting arm 44 undergoes elastic deformation to complete the pressing connection and electrical conduction with the circuit board; on both sides of the terminal plate 41, there are clamping inclined portions 411.

The outer iron shell 50 has a fixing space 51 therein, and a plurality of clamping mechanisms 52 are provided in the outer iron shell 50. When the connector 20 is disposed in the fixing space 51, then the gasket connecting plate 30 is placed into the fixing space 51, and the gasket connecting plate 30 is clamped and positioned by the plurality of clamping mechanisms 52. And the connector 20 is pressed and fixed to the circuit board 10 due to being pressed by the gasket connecting plate 30, thereby completing the electrical connection between the connector 20 and the circuit board 10, that is, the second outer arm portion 443 elastically deforms and abuts against the conductive connection portion 13 of the circuit board 10.

[0037] Please refer to Figure 10 , which is another embodiment of the constitution of the terminal 60 of the connector 20. The terminal 60 includes a terminal plate 61. A central portion of the terminal plate 61 extends to one side and respectively forms two first inner connecting arms 63. The two first inner connecting arms 63 are respectively bent upward and downward to form two second outer connecting arms 64. End portions of the two second outer connecting arms 64 respectively form a second outer connecting arm end portion 65. The pressing and fixing with the circuit board and the electrical connection are completed through the elastic constitution design of the second outer connecting arms 64. And the terminal plate 61 extends and bends upward and downward to form a fitting plate 62 for fixing and positioning.
