摘要： Stamping die for use with a punch to produce holes in strip material with the resulting production of a slug has a camming rib in the die opening. The rib prevents slug pulling when the punch returns from its extended position to its retracted position. The camming rib causes the slug to become wedged in the die opening and is effective to move the slug laterally in its own plane across the leading edge of the punch thereby overcoming any surface tension or other forces which might cause the slug to adhere to the face of the punch. The camming rib can be straight and extend parallel to the axis of the die opening if the die opening is not tapered. If the die opening has a slight taper, the camming rib is inclined thereby to cause movement of the slug across the face of the punch as the punch moves into the die opening.
摘要翻译： 与冲头一起使用的冲压模具在条带材料中产生孔，由此产生块状物，在模具开口中具有凸轮肋。 当冲头从其延伸位置返回到其缩回位置时，肋防止了塞子拉动。 凸轮肋使得块塞楔入模具开口中并且有效地将块塞在其自身的平面中横向移动穿过冲头的前缘，从而克服任何表面张力或其他可能导致块塞附着在表面上的力 的拳头。 如果模具开口不是锥形，则凸轮肋可以是直的并且平行于模具开口的轴线延伸。 如果模具开口具有微小的锥度，则当冲头移动到模具开口中时，凸轮肋条倾斜，从而使块塞移动穿过冲头的表面。

摘要： A continuous strip of spaced-apart electrical contacts is taught. Briefly stated, a mold structure is utilized to position a plurality of contacts in a mold. A polymeric material such as silicone is thereafter injected into the mold which fills the interior portion of the contact as well as encapsulating the exterior upper portion of the contact, thereby producing a strip of spaced-apart electrical contacts having a molded carrier strip of flexible polymeric material. The strip is advanced such that a portion remains in the mold. The mold is then refilled with additional contacts, and the material is again injected to encapsulate the additional contacts as well as to secure this strip to the previous strip.

摘要： A continuous strip of spaced-apart electrical contacts is taught. Briefly stated, a mold structure is utilized to position a plurality of contacts in a mold. A polymeric material such as silicone is thereafter injected into the mold which fills the interior portion of the contact as well as encapsulating the exterior upper portion of the contact, thereby producing a strip of spaced-apart electrical contacts having a molded carrier strip of flexible polymeric material. A series of notches or recesses are formed in the walls of the strip which thereby allows for precise indexing and contact spacing for insertion of the contact strip into a circuit board. The polymeric material which is disposed on the interior of the contact prohibits the introduction of contaminants into the interior of the contact as well as providing a reenterable aperture for placing electrical components having terminal leads.
