Abstract
The utility model provides an electrical coupler used discrimination pin boss, which is composed of a discrimination pin and a discrimination pin boss, wherein, the pin rod of the discrimination pin is inserted in the jack of the discrimination pin boss. The utility model is characterized in that a crown spring is arranged between the discrimination pin and the jack of the discrimination pin boss. Except avoiding the misinsertion of the electrical coupler, the discrimination pin boss also has conduction function, thereby conveniently carrying out the lead grounding, and playing the safeguarding role to the circuit as well as control equipment.
Description
Technical field
The utility model relates to the circuit connector technical field, relates in particular to a kind of circuit connector with differentiating key seat
Background technology
Many cover pairing heads and seat are arranged, when needing corresponding one by one the insertion, in order to prevent that misplug just on the mounting hole site of low frequency rectangle circuit connector two ends, is provided with six squares discriminating key seat in control panel.When supporting plug inserts pedestal, avoided mispluging like this.But this discriminating key seat only can play the discriminating effect, may the hurtful labile state of control electronics not had the safeguard protection effect for what circuit printing plate occurred at work because of overheated and instantaneous break-make.
The utility model content
The purpose of this utility model; be primarily aimed at that circuit printing plate occurs at work because of overheated and instantaneous break-make may be to the hurtful labile state of control electronics, but thereby by providing a kind of novel circuit connector with differentiating that key seat realizes that lead-out wire ground connection reaches the safeguard protection effect.
The purpose of this utility model is achieved by the following technical solution: a kind of circuit connector is with differentiating key seat, form by discriminating pin, discriminating key seat, the pin rod of described discriminating pin inserts in the jack of differentiating in the key seat, it is characterized in that being provided with the hat spring between the jack in discriminating pin and discriminating key seat
On the jack sidewall of differentiating key seat, can offer gathering sill vertically, on the sidewall of discriminating pin pin rod, be provided with the guide pad that matches with above-mentioned gathering sill.
The outer end portion of jack can be provided with deck in the described discriminating key seat, and the hat spring locating piece of ring-type is housed in this deck, have on the hat spring locating piece sidewall with differentiate key seat jack sidewall on the corresponding groove of gathering sill.
One end of described discriminating key seat is threaded cylinder, and the other end is the orthohexagonal body, and described jack is positioned at the orthohexagonal body; One end of described discriminating pin is the cylinder pin rod of band flat guide pad, and the other end is the orthohexagonal body.
During use, after discriminating pin insert to be differentiated in the key seat, not only differentiate with routine that key seat is the same and can avoid misplug; Simultaneously owing to embedded hat spring body, " pin " and " jack " of the discriminating key seat that is equipped with the hat spring by discriminating pin forms closely face and contact rightly, guaranteed the high reliability that contacts, and just can take on the function of conducting so in a single day switch on.Like this; when need to circuit printing plate occur at work may take measures to the hurtful labile state of control electronics because of overheated and instantaneous break-make the time, thereby circuit connector described in the utility model with differentiate key seat just easily lead-out wire ground connection reach the safeguard protection effect.
Description of drawings
Fig. 1 is that discriminating pin assembles decomposing schematic representation with differentiating key seat.
Fig. 2 differentiates key seat, hat spring and hat spring locating piece assembling decomposing schematic representation.
Embodiment
The utility model is made up of discriminating pin 1, discriminating key seat 2 and hat spring 3, and an end of described discriminating pin is the cylinder pin rod 4 of band flat guide pad 6, and the other end is an orthohexagonal body 5.One end of described discriminating key seat 2 is threaded cylinder 7, and the other end is an orthohexagonal body 8, is provided with jack 9 vertically in the orthohexagonal body 8 of differentiating key seat 2, and the outer end portion of this jack 9 is provided with the deck 12 that can hold hat spring locating piece 11.Hat spring locating piece 11 is a ring-type, has the groove corresponding with gathering sill 10 on its sidewall.Offer gathering sill 10 vertically on these jack 9 sidewalls, this gathering sill 10 can match with the guide pad 6 on the discriminating pin pin rod 4.
Hat spring 3 described in the utility model is interior receipts swelling-waist shape, and structure is the phosphor bronze parts of drawing, surface gold-plating.Its contact resistance is little, and conductance is good, has the high reliability of contact, is easy to large-scale production.
When the utility model uses, hat spring 3 is inserted the jack of differentiating in the key seat 29, and will be preced with spring locating piece 11 and firmly embed in the deck 12, owing to the endoporus edge of deck 12 is an elasticity, and internal diameter is less than the external diameter of hat spring locating piece 11, and therefore being preced with spring locating piece 11 can play the role of positioning to the hat spring.When discriminating pin 1 inserts discriminating key seat 2, only need band flat guide pad 6 alignings of discriminating pin one end are differentiated that 10 insertions of the gathering sill on jack 9 sidewalls get final product in the key seat 2.
Claims (5)
1. a circuit connector is used and is differentiated key seat, is made up of discriminating pin, discriminating key seat, and the pin rod of described discriminating pin inserts in the jack of differentiating in the key seat, it is characterized in that being provided with the hat spring between the jack in discriminating pin and discriminating key seat.
2. a kind of circuit connector according to claim 1 is characterized in that offering gathering sill vertically on the jack sidewall of differentiating key seat with differentiating key seat, is provided with the guide pad that matches with above-mentioned gathering sill on the sidewall of discriminating pin pin rod.
3, a kind of circuit connector according to claim 2 is with differentiating key seat, the outer end portion that it is characterized in that jack in the described discriminating key seat is provided with deck, the hat spring locating piece of ring-type is housed in this deck, have on the hat spring locating piece sidewall with differentiate key seat jack sidewall on the corresponding groove of gathering sill.
4, according to claim 1 or 2 or 3 described a kind of circuit connectors discriminating key seats, an end that it is characterized in that described discriminating key seat is threaded cylinder, and the other end is the orthohexagonal body, and described jack is positioned at the orthohexagonal body; One end of described discriminating pin is the cylinder pin rod of band flat guide pad, and the other end is the orthohexagonal body.
5, according to claim 1 or 2 or 3 described a kind of circuit connectors discriminating key seats, it is characterized in that described hat spring is interior receipts swelling-waist shape.
