Abstract
The invention discloses an elastic terminal, comprising: a fixed part; and a first elastic arm connected to the fixing portion. The elastic terminal further includes: and the second elastic arm is positioned at the inner side of the first elastic arm and is connected to the fixed part. When a contact pressure is exerted on the outer side of the first spring arm, the second spring arm rests against the inner side of the first spring arm, so as to bear together with the first spring arm the contact pressure exerted on the outer side of the first spring arm. In the present invention, since the spring arm of the spring terminal includes the first spring arm and the second spring arm located inside the first spring arm, the contact pressure applied to the first spring arm can be borne by both the first spring arm and the second spring arm. Therefore, the contact pressure that the elastic arm of the elastic terminal can bear can be doubled without increasing the size of the elastic terminal, which is beneficial to the miniaturization of the size of the elastic terminal.
Description
Technical Field
The present invention relates to an elastic terminal.
Background
In the prior art, it is sometimes necessary to prevent signals transmitted in an electronic product from being subjected to external electromagnetic interference, and at this time, it is necessary to mount elastic terminals (or called elastic electromagnetic shields) on the peripheral walls of an insertion port of a housing of the electronic product. When the electronic product is matched with the matched electronic product, the elastic terminal is squeezed between the electronic product and the shell of the matched electronic product, so that the electronic product and the shell of the matched electronic product are reliably electrically connected.
In the prior art, such an elastic terminal generally includes a welding fixing portion adapted to be welded to a wall surface of the housing, and an elastic arm portion extending from the welding fixing portion to be bent upward. The elastic arm portion of the conventional elastic terminal is formed by bending a single-layer elastic sheet, but with the demand for more and more miniaturization of electronic products, not only the electronic products are required to have smaller dimensions in the length direction and the width direction, but also the electronic products are required to have smaller dimensions in the height direction. This results in the size of the sprung terminal being increasingly smaller.
Since the yield strength of the elastic material of the elastic terminal is limited, when the size of the elastic terminal is too small, the contact pressure that the elastic arm portion of the elastic terminal can bear is limited, and when the contact pressure applied to the elastic arm portion is too large, the elastic arm portion is easily crushed, which is not favorable for miniaturization of the electronic product.

According to one general technical concept of the present invention, there is provided an elastic terminal including: a fixed part; and a first elastic arm connected to the fixing portion. The elastic terminal further includes: and the second elastic arm is positioned at the inner side of the first elastic arm and is connected to the fixed part. When a contact pressure is exerted on the outer side of the first spring arm, the second spring arm rests against the inner side of the first spring arm, so as to bear together with the first spring arm the contact pressure exerted on the outer side of the first spring arm.
Fig. 1 shows a perspective view of a sprung terminal according to one embodiment of the invention; fig. 2 is a schematic view showing the elastic terminal shown in fig. 1 when it is elastically contacted with the compression member 10; and fig. 3 shows a longitudinal sectional view of the elastic terminal shown in fig. 1.
As shown in fig. 1 to 3, in the illustrated embodiment, the elastic terminal mainly includes: a fixed portion 110, a first resilient arm 120, and a second resilient arm 200. The fixing portion 110 of the elastic terminal is adapted to be welded to, for example, a wall surface of a housing of an electronic product. The first elastic arm 120 is connected to the fixing portion 110. The second elastic arm 200 is located inside the first elastic arm 120 and connected to the fixing portion 110.
As shown in fig. 2, in the illustrated embodiment, when the first elastic arm 120 is elastically contacted with the compression member (e.g., the housing of the counterpart electronic product) 10, the second elastic arm 200 abuts against the inner side surface of the first elastic arm 120, and bears the contact pressure applied on the outer side of the first elastic arm 120 together with the first elastic arm 120. Therefore, the contact pressure that the elastic arm of the elastic terminal can bear can be doubled without increasing the size of the elastic terminal, which is beneficial to the miniaturization of the size of the elastic terminal.
As shown in fig. 1, 2 and 3, in the illustrated embodiment, the first resilient arm 120 includes: a first transition portion 121 connected to the rear end 111 of the fixing portion 110 and bent upward along an arc-shaped path from the rear end 111 of the fixing portion 110; a first extension part 122 connected to the first transition part 121 and horizontally extending forward from the first transition part 121; and a second extension 123 connected to the first extension 122 and extending obliquely forward and upward from the first extension 122.
As shown in fig. 1, 2 and 3, in the illustrated embodiment, the second resilient arm 200 includes: a base portion 210 connected to an inner side surface of the rear end 111 of the fixing portion 110; a first transition section 211 connected to the base 210 and bent upward from the base 210 along an arcuate path; a first extension 212 connected to the first transition section 211 and horizontally extending forward from the first transition section 211; and a second extension 213 connected to the first extension 212 and extending obliquely forward and upward from the first extension 212.
As shown in fig. 1, 2 and 3, in the illustrated embodiment, the first transition section 211, the first extension section 212 and the second extension section 213 of the second resilient arm 200 correspond to the first transition portion 121, the first extension portion 122 and the second extension portion 123 of the first resilient arm 120, respectively.
As clearly shown in fig. 2, in the illustrated embodiment, when the first resilient arm 120 is subjected to the contact pressure applied by the compression member 10, at least a portion of the second extension 213 of the second resilient arm 200 is in contact with the second extension 123 of the first resilient arm 120, and the first transition 211 and the first extension 212 of the second resilient arm 200 are not in contact with the first transition 121 and the first extension 122 of the first resilient arm 120. Therefore, the elastic arm of the elastic terminal can be ensured to have good elasticity under the condition of improving the compression resistance of the elastic arm of the elastic terminal.
As shown in fig. 1, 2 and 3, in the illustrated embodiment, the first resilient arm 120 further comprises: a second transition portion 124 connected to the second extension portion 123 and bent downward from the second extension portion 123 along an arc-shaped path; and a third extension 125 connected to the second transition portion 124 and extending rearward and downward from the second transition portion 124. The distal end portion 125a of the third extension portion 125 is slidably supported on the inner side surface of the fixing portion 110. Thus, the entire first spring arm 120 acts as a simple beam, which further increases the compression resistance of the spring arm of the spring terminal.
As shown in fig. 1, 2 and 3, in the illustrated embodiment, the distal end portion 125a of the third extending portion 125 has a smooth arc-shaped end surface 125al, and the smooth arc-shaped end surface 125al is in sliding contact with the inner side surface of the fixing portion 110.
As shown in fig. 1, 2 and 3, in the illustrated embodiment, a convex contact portion 120a adapted to contact the compression member 10 is formed at the top of the first elastic arm 120.
As shown in fig. 1, 2 and 3, in the illustrated embodiment, the second transition portion 124 is located at the top of the first resilient arm 120, and the contact portion 120a is formed on the outer surface of the second transition portion 124.
As shown in fig. 1, 2 and 3, in the illustrated embodiment, the elastic terminal further includes a pair of sidewalls 130 located at both sides of the front end 112 of the fixing portion 110; and the distal end portions 125a of the third extensions 125 of the first resilient arms 120 are constrained between the pair of side walls 130.
As shown in fig. 1, 2 and 3, in the illustrated embodiment, the base portion 210 of the second resilient arm 200 is welded to the inner side surface of the rear end 111 of the fixed portion 110.
As shown in fig. 1, 2 and 3, in the illustrated embodiment, the fixing portion 110 has a flat bottom surface adapted to be welded to a panel (e.g., a wall surface of a housing of an electronic product).
