Abstract
The utility model discloses an elastic contact piece with a concentric positioning function, comprising a head part (1), a tail part (3) and an installing part (2) arranged between the head part (1) and the tail part (3). The head part (1) is provided with positioning components for being fixed in base holes (40); the positioning components are positioning claws (11), wherein the end parts of the positioning claws (11) are splayed outwards, and the extent is enough to be larger than the apertures of the base holes (40); the head part (1) is provided with at least two spring leaves (12); the end parts of the spring leaves (12) are axially inclined; a plurality of spring leaves (12) are evenly distributed; and each positioning component is arranged between two adjacent spring leaves (12). The elastic contact piece with the concentric positioning function has good concentricity with the base holes, the cooperative relationship between the installing positions and the base has little influence on the concentricity, and the connection performance is stable and reliable.
Description
Technical field
The utility model relates to electric connector field, specifically relates to be applied to the resilient contact in the connector, especially relates to a kind of resilient contact that is installed in the pedestal hole and concentric requirement is arranged with it.
Background technology
General known resilient contact as shown in Figure 1, it comprises head 1, afterbody 3 and be located at head 1 and afterbody 3 between installation portion 2, one end of head 1 has two or more grooves 13, make head form two or more reeds 12, simultaneously, the end of reed 12 tilts to axis, and make the contact size of finish dimensional less than correspondence, when contact pin inserts, pressure makes the oral area of reed 12 open, the oral area of reed 12 and contact pin contact position produce pressure, reach contact pin and form the purpose that is electrically connected, when inserting reed 12 is opened, so when not inserting contact pin owing to contact pin with resilient contact, between reed 12 and the pedestal hole suitable gap must be arranged, match with pedestal and make resilient contact and base position concern relative fixed.Like this, resilient contact is fixed on and is formed with flexible cantilever beam structure in the pedestal.Owing to change, the structure of processing dimension are limit and are made the very short and assembling deviation of standing part or the like reason, resilient contact installation position and pedestal hole decentraction, and because cantilever beam has amplification to the decentraction amount of fixed position, cause resilient contact head and pedestal hole to produce bigger deflection, cause connector function to lose efficacy.
The utility model content
The purpose of this utility model is: the resilient contact with concentric locating function that matching relationship is little to the concentricity influence, switching performance is reliable and stable that a kind of good concentricity, installation position and pedestal of and pedestal hole are provided.
The technical solution of the utility model is: a kind of resilient contact with concentric locating function, it comprise head, afterbody and be located at head and afterbody between installation portion, described head is provided with and is used in the pedestal hole fixing positioning element.
Below technique scheme is further explained:
Described positioning element is the outside open locating detent in end, and its amount of opening is greater than aperture, pedestal hole.
Described head is provided with at least two reeds, and leaf end tilts to axis.
Described a plurality of reed evenly distributes.
Described positioning element is located between two adjacent reeds.
Described positioning element is made of the otch material between adjacent two reeds.
Described positioning element is an elastomeric element.
The utility model has the advantages that:
1, the simple beam structure form is taked in the installation of resilient contact of the present utility model, resilient contact head and installation portion all install and fix with the pedestal hole, and the head standing part adopts the elastomeric material interference fit, can not produce the gap, guarantee the concentricity in plug oral area and pedestal hole, the matching relationship of installation position and pedestal (gap, interference) is very little to the concentricity influence.
2, known resilient contact is circumferentially evenly slotted and is formed the identical two or more reeds of physical dimension, and the opening part material is removed.The utility model then is only to make otch, and two otch intermediate materials then form locating detent, and therefore, the utility model processing technology is simple, saves material.
3, positioning element of the present utility model outwards opens, and its amount of opening is bigger than described pedestal hole, form interference fit with pedestal, form simple beam structure together with two fulcrums with original fixed position, install more reliable and more stable, head and pedestal hole always keep fitting tightly, and be effective with one heart.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is the structural representation of the utility model embodiment;
Fig. 3 is the mounting structure schematic diagram of the utility model embodiment;
Wherein: 1 head; 2 installation portions; 11 locating detents; 12 reeds; 13 grooves; 3 afterbodys; 4 pedestals; 40 pedestal holes; 41 hole walls.
Embodiment
Embodiment: as shown in Figure 2, the resilient contact of the utility model embodiment comprises head 1, afterbody 3, is located at the installation portion 2 between head 1 and the afterbody 3, and head 1 is provided with and is used for 40 locating detents of fixing 11 in the pedestal hole.
As shown in Figure 3, in the present embodiment, locating detent 11 outwards opens for the end, and its amount of opening is bigger than pedestal hole 40.In the present embodiment, head 1 is provided with two reeds 12 that the end tilts to axis, and locating detent 11 is located between two adjacent reeds 12, and on the reed 12, locating detent 11 even distribution heads 1.The end makes head 1 slope inwardly to two reeds 12 that axis tilts, thereby makes the contact size of contact opening less than correspondence, guarantees when contact pin inserts and contact pin has contact pressure, and formation electrically contacts, and finishes the electrical connection function.
When resilient contact is installed in the pedestal 4, locating detent 11 and the hole wall 41 in pedestal hole 40 closely contact head 1 are supported and fixed on position in the pedestal hole 40.Simultaneously, installation portion 2 also is installed in the hole wall 41 in pedestal hole 40, and like this, resilient contact is installed in the pedestal hole 40 by locating detent 11 and installation portion 2 in the axial direction and is fixed.Because the external diameter that all locating detent 11 forms is greater than pedestal hole 40 diameters, thus locating detent 11 always combine closely with hole wall 41, thereby the concentric purpose in the head 1 that has reached contact and pedestal hole 40.
In addition, also can on head 1, be provided with more reed 12 and more locating detent 11 as required.
Should be pointed out that for the utility model also to have the embodiment of multiple conversion and remodeling, be not limited to the specific embodiment of above-mentioned execution mode through proving absolutely.The foregoing description is as just explanation of the present utility model, rather than restriction.In a word, protection range of the present utility model should comprise those conspicuous to those skilled in the art conversion or substitute and remodeling.
