Description

Connection terminal seat

The utility model is a kind of structure of terminal block, refers to the improvement of the terminal base that wiring is used to the power supply letter especially.

The terminal block that telecommunications is used, unlike the consumer goods often as seen, have only relevant engineers and technicians just can be familiar with.Therefore, the research and development of this series products are seemed slowly, and exist many problems that have much room for improvement.Be difficult for assembling such as each assembly of terminal base, relatively, be not easy dismounting during repairing; In addition, lack the subscriber protector or the telephone subscriber loop telemetry interface isolator of " single channel ", adapt to the security device or the automation installation that become many day by day; Moreover existing terminal block also lacks the device of common ground, with grounding electrode of all protectors of tandem etc.

Existing terminal block need be pulled down recombinant often with variant terminal socket sometimes on pedestal in test, operation inconvenience and quick inadequately is so be necessary to do further improvement.

The purpose of this utility model is to provide a kind of and need use instrument, can pedestal and connector socket be carried out the terminal block of assembly and disassembly with hand; Another purpose of the present utility model is to provide a kind of terminal block, and its common ground shell fragment can combine with the bottom of socket securely, and the grafting because of protector is got loose.

For achieving the above object, the utility model has designed a kind of terminal block, and this terminal block has a U-shaped pedestal (1), with at least one socket (2) that bears on above-mentioned pedestal (1), it is characterized in that:

Socket (2) is by a loam cake (22) with most seat holes (221), with inner common a composition of bottom (21) of inserting intrinsic common ground shell fragment (23);

Pedestal (1) both sides are parallel and respectively be not provided with an opening bottle shaped trench (12) on the supporting wall (11) of setting in opposite directions, and these bottle shaped trench (12) respectively have a neck (122);

The two bottom sides of socket (2) respectively has a common ground rod (24) that is slightly larger than above-mentioned bottle shaped trench neck (122), cover is put in the bottle shaped trench (12), make bottle shaped trench can become the shaft seat of socket, and make socket (2) and pedestal (1) only depend on hand-power can be one-sided or both sides separate each other or make up.

Common ground shell fragment (23) is except respectively being provided with in the rear and front end the clip (232), and its waist also is provided with at least one pair of clip (233), make with above-mentioned bottom (21) fit after can firmly clamp bottom (21).

U-shaped pedestal of the present utility model (1) can bear a socket (2), and the U-shaped pedestal also can be provided with many supporting walls to neighbour setting (11), and every pair of supporting wall (11) bears a socket (2).

Below in conjunction with drawings and Examples, 26S Proteasome Structure and Function of the present utility model is described further.

Accompanying drawing 9: the cutaway view that is cut along the line A-A of accompanying drawing 7.

Shown in Fig. 1-6, the embodiment of terminal block of the present utility model has a U-shaped pedestal (1) and socket (2), can bear a socket (2) on the pedestal (1), but also can make a pedestal (1) mate many sockets (2) where necessary, as shown in Figure 1.

The metallic object that pedestal (1) is formed in one, respectively there is supporting wall (11) its both sides, respectively be provided with an opening bottle shaped trench (12) on these supporting walls (11), bottle shaped trench (12) by an opening circular recess (121) with form by the upwardly extending neck of circular recess (122).As shown in the figure, each supporting wall (11) is parallel to each other and in opposite directions non-, so these bottle shaped trench (12) are also parallel to each other and not in opposite directions.

Socket (2) is by a loam cake (22) with most seat holes (221), with inner common a composition of bottom (21) of inserting an intrinsic common ground shell fragment (23).The bottom of socket (2), as Fig. 2, shown in 5 and 6, its both sides respectively have a common ground rod (24), the diameter of this common ground rod is greater than the neck (122) of the bottle shaped trench (12) of pedestal (1), therefore, during the neck (122) of these common ground rods (24) by bottle shaped trench, application of force amount slightly, neck is strutted slightly, and these common ground rods (24) can be deviate from from bottle shaped trench (12) then, perhaps enter in the circular recess of bottle shaped trench, once enter in the circular recess, the having in conjunction with effectiveness of generation: (one) can make common ground shell fragment (23) mat common ground rod (24) conducting in pedestal (1) because of contact; (2) common ground rod (24) is not deviate from easily in bottle shaped trench (12), be made socket (2) and pedestal (1) firm combination; (3) after an end of socket (2) was separated with pedestal (1) earlier, bottle shaped trench (12) can become the rotating shaft of the common ground rod (24) of socket, makes socket (2) can raise swing; (4) need not utilize other instruments, be disassembled or combination with hand-power.

Another feature of the present utility model, as Fig. 1, shown in 7,8 and 9, common ground shell fragment (23) upper end has most to Spring sheet clip (231), and its quantity is identical with the quantity in the seat hole (221) of loam cake (22) central authorities.The rear and front end of common ground shell fragment (23) respectively is provided with a clip (232), and waist also can be provided with at least one pair of clip (233), after being inserted in the bottom (21) of socket, not only the clip of front and back end (232) can fasten bottom (21), but its waist also mat clip (233) fastens bottom (21) securely, this structure can improve when protector (3) or other analogs and Spring sheet clip (231) when separating, and makes the shortcoming of the loosening distortion of common ground shell fragment (23) waist.The two ends of described common ground shell fragment (23) and common ground rod (24) conducting.Moreover, the loam cake (22) of socket (2), its hole (221) are provided with guide groove (224), as shown in Figure 1, are used for cooperating the raised line (31) of protector (3) lower end, and the unlikely lane of direction when protector (3) is inserted is anti-.

Shell fragment in the socket in the prior art (2) has two kinds of forms, and a kind of another kind then is not suitable for the grafting protector in order to be suitable for the protector person, and each protector relative socket aperture all need indivedual ground connection, can not be interchangeable.But the utility model provides the common ground shell fragment in socket (2), applicable to after no matter what protectors are pegged graft, all can common ground, and construction is simply.And when being used for pegging graft protector, the grounding elastic part in the socket (2) removed get final product, needn't be as existing structure, need be with the whole replacing of socket.

The utility model has the advantages that: simple in structure, than the easier combination of existing terminal block with disassemble, need not use any instrument, can pedestal and connector socket be assembled or dismantle with hand, very easy to use, and can be applicable to the group of tearing open of different purposes.
