Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the fixture of plug-in relay comprises keeping seat 10, main body 20, enclosing cover 30.
Referring to Fig. 2, keep seat 10 to be shaped as a box body shape, be to be used for holding relay.On the base plate 11 that keeps seat 10 groove 12 is arranged, this groove 12 is corresponding with the relay contact, so that relay is placed on when keeping in the seat 10, the relay contact stretches out in groove 12.Keep biside plate 13 upper ends of seat that " Г " shape elastic hook 14 is arranged, its effect is to be used for clamping relay.During free state, two " Г " shape elastic hook 14 outwards opens.In this embodiment, two " Г " shape elastic hook is symmetrical, and " Г " shape elastic hook 14 outside open angles are 5-15 degree (angle between two " Г " shape elastic hook is the 10-30 degree), puts into or takes out with convenience relay.
Referring to Fig. 3, the top of main body 20 be provided with one with keep seat 10 corresponding joint portions 21, keep seat 10 to move up and down along this joint portion 21.There is the guiding surface 211 that play the guiding role 21 upper end in the joint portion, so that keep putting into of seat 10.When keeping seat 10 to pack in the joint portion 21 of main body, between the medial surface of " Г " shape elastic hook 14 and the side of relay certain clearance is arranged, along with keeping being pressed into of seat 10, " Г " shape elastic hook 14 is under the squeezing action of joint portion 21, inwardly draw in, fade away in the gap, " Г " shape elastic hook 14 clamps relay, and the protrusion transverse slat of " Г " shape elastic hook 14 can prevent further that relay from dropping out.
In the bottom of main body 20 metal terminal installation portion 22 is arranged, this metal terminal installation portion 22 is a square groove shape, interior placement metal terminal 40, and the upper end of metal terminal is the resilient clip opening 41 that is used to clamp the relay contact.The metal terminal installation portion 22 of square groove shape is corresponding with 40 size dimensions of metal terminal, and expose outside the main body 20 lower end 42 of metal terminal 40, can directly be connected with pcb board, promptly uses Relay base to realize connecting.
Be provided with an ejection piece 50 at the middle part of main body 20, be used for maintenance seat 10 is ejected.Ejection piece 50 is made up of knock-pin 51 and push rod 52.The two sides, middle part of knock-pin 51 are provided with protrudes columnar portion 511, and this protrudes the rotation back shaft of columnar portion 511 as knock-pin 51.Second circular hole 33 that protrudes first circular hole 24 on columnar portion 511 and the main body and cover outward is corresponding.The left end of knock-pin 51 is provided with the lug boss 512 that raises up.Push rod 52 is installed in the push rod groove 23 on the main body 20, and the lower end of push rod 52 is connected with the right-hand member of knock-pin 51.For the ease of the downward application of force push rod is depressed, the upper end of push rod 52 is provided with " U " shape groove 521.When pressing down push rod 52, push rod 52 drives knock-pin 51 right-hand members and moves downward, knock-pin 51 turns clockwise around protruding columnar portion 511, the lug boss 512 of knock-pin 51 left ends will keep seat 10 upwards to eject, relay 60 is with keeping seat 10 to move upward, the resilient clip opening 41 of relay contact and metal terminal 40 breaks away from, and relay can be taken out.
Referring to Fig. 4, drop out in order to prevent metal terminal 40 and ejection piece 50, at the lateral surface of main body 20 enclosing cover 30 is arranged, main body 20 is provided with protuberance 25, and the medial surface of enclosing cover 30 is provided with and protuberance 25 corresponding clamping parts 31.Lower inside at enclosing cover 30 has protruding location division 32, and location division 32 is corresponding with the metal terminal installation portion 22 on the main body 20, further the position of fixing metal terminal 40.In addition, enclosing cover 30 can also prevent to keep seat 10 to skid off in the joint portion 21 of main body, plays the effect that keeps seat 10 horizontal movements that limits.
During installation, referring to Fig. 5,6, in the metal terminal installation portion 22 of main body 20 bottoms of earlier metal terminal 40 being packed into; Push rod 52 is packed in the push rod groove 23 of main body, and the protrusion columnar portion 511 of knock-pin 51 1 sides is inserted in first circular hole 24 of main body 20, and the right-hand member of knock-pin 51 places the below of push rod 52; Keep seat 10 parts to put into the joint portion 21 on main body 20 tops, and keep " Г " shape elastic hook 14 of seat 10 to expose above joint portion 21.Cover on main body 20 with enclosing cover 30, fasten grab (the protrusion columnar portion 511 of knock-pin 51 another sides just is inserted in second circular hole 33 of enclosing cover 30).
During use, shown in Fig. 7,8, put into relay 60, and the bottom of relay 60 is contacted with the bottom that keeps seat, under the promotion of external force, relay 60 and maintenance seat move downward along the joint portion of main body together, keep " Г " shape elastic hook of seat both sides also close to the relay side under the extruding of body simultaneously, when being pushed into position shown in Figure 8, relay arrives the bottom, joint portion, " Г " shape elastic hook clamps relay at this moment, and latching relay can not drop out.In this process, keep the base plate of seat also can force the lug boss of knock-pin to move down, the right-hand member of knock-pin moves up, and makes push rod also be moved upwards up to the upper end.When needs are removed relay, this moment, external force put on " U " shape groove place of push rod, push rod moves down, the lug boss that drives knock-pin moves upward, keep seat to move up thereby make,, keep this moment " Г " shape elastic hook of seat both sides to recover open configuration until the top, the resilient clip opening 41 of relay contact and metal terminal 40 also breaks away from, relay can be taken out.
Basic principle of the present utility model, principal character and advantage of the present utility model have more than been described.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in the foregoing description and the specification is principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in the claimed scope of the present utility model.The protection range that the utility model requires is defined by appending claims and equivalent thereof.
