Abstract
The utility model relates to a dry-reed relay, which comprises a skeleton 1, a coil 2 which is wound on the external side of the skeleton, and at least two ferromagnetic metal elements 3, 4 which are arranged in the skeleton and can be contacted, wherein, at least one metal element is the ferromagnetic reed. The dry-reed relay is characterized in that the ferromagnetic metal elements are directly fixed onto the relay skeleton, and accordingly, the dry-reed relay has the advantages of simple structure, high positioning accuracy, good reliability, low cost, and long service life.
Description
The utility model belongs to relay, is specifically related to a kind of improvement of dry-reed relay.
Existing dry-reed relay all has the tongue tube that includes reed of a glass packaging, and the electromagnetic field that utilizes coil to produce makes the ferromagnetism reed magnetization in the tongue tube and adhesive and connect circuit mutually realizes the function of relay.The packaging sintering technology of the glass tube of this reed switch relay and equipment more complicated cannot say for sure that also the reed of demonstrate,proving in the tongue tube has enough positioning accuracies, so reliability is relatively poor, cost is also higher, and glass tube are easy to break.
The purpose of this utility model is to provide that a kind of cost is lower, simple in structure, the dry-reed relay of dependable performance.
Dry-reed relay of the present utility model, comprise a relay skeleton and be arranged on intraskeletal at least two ferromagnetic metal spares that keep certain distance and can contact, skeleton is around with coil, its characteristics are that these two reeds directly are fixed on the relay skeleton, behind the coil electricity outside the skeleton, the electromagnetic field that produces makes intraskeletal reed magnetization and adhesive, the connection circuit.
Accompanying drawing is the structural representation of dry-reed relay of the present utility model.
As shown in the figure, dry-reed relay of the present utility model comprises skeleton 1, the coil 2 outside skeleton and directly be fixed on intraskeletal two ferromagnetic metal sheets 3 and 4 that keep certain distances but can contact.
Relay skeleton of the present utility model, coil and ferromagnetic metal contact or reed Design, making all belong to prior art, can continue to use the design of shaped framework coil and the ferromagnetic metal contact of any existing dry-reed relay, having these ferromagnetic metal contacts only is directly to be fixed on the relay skeleton, during making, as shown in the figure, these ferromagnetic metal spares can directly be embedded in the skeleton when the injection moulding skeleton, also can insert in the internal frame, give in fixing again.
The relay skeleton generally adopts prior art engineering plastics commonly used, makes the I shape skeleton of the cavity that is used to be provided with above-mentioned ferromagnetic metal spare.
According to the working method of relay, described ferromagnetic metal spare can be two ferromagnetic metal reeds; Also can a ferromagnetic metal reed, another then is a rubber-like ferromagnetic metal spare not; It can also be the change type working method that two ferromagnetic metal spares and non-ferromagnetic metal spare constitute.
Good in order to ensure contact between feeromagnetic metal spare, be preferably in the reed end high stability material contact is set.
Compare with the existing relay that tongue tube was constituted that includes reed with glass packaging, relay of the present utility model is owing to directly be fixed on ferromagnetic metal spare on the relay skeleton, therefore manufacture craft and simple in structure, positioning accuracy is high, therefore good reliability, cost are also low, nor damage long service life easily.
Embodiment
A kind of " 700 Ω " dry-reed relay as the cordless telephone control element, long 25 millimeters, wide 9 millimeters of the I shape skeleton that the ABS engineering plastics are made, two iron-nickel alloy reed ends are at a distance of 0.08 millimeter, two reeds directly are fixed within the skeleton by being embedded in intraskeletal pin, two reed ends are provided with the contact of plating with high stability material gold, and the distance between two pins is 23.5 millimeters.
Claims (1)
1, a kind of dry-reed relay, comprise relay skeleton (1), be arranged on intraskeletal at least two ferromagnetic metal spares that can contact (3) and (4), wherein at least one metalwork is the ferromagnetism reed, the relay skeleton is around with coil (2), it is characterized in that above-mentionedly being arranged on the intraskeletal metalwork that can contact and directly being fixed on the relay skeleton.
