Abstract
A spring system arrangement and a related connector are disclosed. The purpose is to allow the use of contact springs, such as coil contact springs, with relatively large size body, to be located on a small center distance, i.e. pitch, and to electrically connect with contact pads of high density electronic devices, having a small device pitch. The device pitch can be smaller than the diameter of the spring body itself. In order to achieve this desired small spring pitch and high density, the contact springs are located in a nested head-to-toe and/or staggered orientation. Furthermore, the connectors utilize guide plates, referred to as combs, to accurately control the alignment of the contact springs tips to the contact pads of the electronic devices.
Claims15
A system for making electrical connection to an electronic device having at least a first and a second contact features, located in a pattern, with a small center distance between said contact features, the system
- comprising:
- a) at least one guide plate, being configured to form a comb, having at least a first and a second apertures for attachment to contact springs, said apertures being disposed in a similar pattern as said pattern of said electronic device and with a small center distance between said apertures, being equal in size to the small center distance between said contact features of said electronic device;
- and
- b) at least a first contact spring, having a body, said body having a large diameter or girth, and having a first and a second end, and said spring having a first and a second slender, said pushers having a diameter or girth smaller than that of said body, and said pushers having different length, said first pusher being long and having one of its two ends located next to said first end of said body and its second end being free and as the spring toe free end, while said second pusher being shorter than said first pusher and having one of its two ends located next to said second end of said body and its second end being free and as the spring head free end, and
- c) a second contact spring, similar in shape and features to said first contact spring, and
- d) said contact springs being placed adjacent to each other, and
- e) one free end of said first contact spring passing through said first aperture of said comb, and
- f) one free end of said second contact spring passing through said second aperture of said comb
- wherein
- g) said contact springs are arranged in form of a head-to-toe orientation with respect to each other, wherein said short pusher of said second contact spring is adjacent to said long pusher of said first contact spring, and said long pusher of said second contact spring is adjacent to said short pusher of said first contact spring.
A system for making electrical connection to an electronic device having at least a first and a second contact features, located in a pattern, with a small center distance between said contact features, the system
- comprising:
- a) at least a first contact spring, having a body, said body having a large diameter or girth, and having a first and a second end, and said spring having a first and a second slender pushers, said pushers having a diameter or girth smaller than that of said body, and said pushers having different length, said first pusher being long and having one of its two ends located next to said first end of said body and its second end being free and as the spring toe free end, while said second pusher being shorter than said first pusher and having one of its two ends located next to said second end of said body and its second end being free and as the spring head free end, and
- b) a second contact spring, similar in shape and features to said first contact spring, and
- c) said contact springs being placed adjacent to each other,
- wherein
- d) said contact springs are arranged in form of a head-to-toe orientation with respect to each other, wherein said short pusher of said second contact spring is adjacent to said long pusher of said first contact spring, and said long pusher of said second contact spring is adjacent to said short pusher of said first contact spring.
A system for making electrical connection to an electronic device having at least a first and a second contact features, located in a pattern, with a small center distance between said contact features, the system
- comprising:
- a) at least one guide plate, being configured to form a comb, having at least a first and a second apertures for attachment to contact springs, said apertures being disposed in a similar pattern as said pattern of said electronic device and with a small center distance between said apertures, being equal in size to the small center distance between said contact features of said electronic device;
- and
- b) at least a first contact spring, having a body, said body having a large diameter or girth, and having a first and a second end, and said spring having a first and a second slender pushers, said pushers having a diameter or girth smaller than that of said body, and said pushers having different length, said first pusher being long and having one of its two ends located next to said first end of said body and its second end being free and as the spring toe free end, while said second pusher being shorter than said first pusher and having one of its two ends located next to said second end of said body and its second end being free and as the spring head free end, and
- c) a second contact spring, similar in shape and features to said first contact spring, and
- d) said contact springs being placed adjacent to each other, and
- e) one free end of said first contact spring passing through said first aperture of said comb, and making contact with said first contact feature of said electronic device, and
- f) one free end of said second contact spring passing through said second aperture of said comb and making contact with said second contact feature of said electronic device
- wherein
- g) said contact springs are arranged in form of a head-to-toe orientation with respect to each other, wherein said head free end of said first contact spring is adjacent to said toe free end of said second contact spring, and said toe free end of said first contact spring is adjacent to said head free end of said second contact spring.
