Description

Binding post

Technical field

The utility model belongs to technical field of electronic devices, relates to a kind of binding post, particularly relates to a kind of binding post.

Background technology

Binding post mostly in the market is several working of plastics and copper piece assembles, with other mechanisms, binding post is fixed on product during installation, binding post afterbody leaves welding position, can by the electronic welding of connection in welding position, play the effect of conducting, the following shortcoming of these binding post ubiquities, 1. operating efficiency is low; 2. binding post easily loosens after installing, and is because vibration mostly; 3. binding post needs welding or on line after installing, and the hidden danger and the junction that there is again rosin joint loosen the loose contact caused; In addition when assembling production, there is higher requirement to the technical merit of welding procedure and operating personnel.

Following accompanying drawing 4 is the binding posts in first technology, it is made up of wiring hole 12, screwed hole 13 and binding post 14, the shortcoming of this technology is, when binding post is fixedly linked into and circuit board carries out welding job, needs to find other fixed structures and fixes circuit board, carrying out welding job, but still there will be rosin joint or weld loosens the loose contact caused, thus cause more defective products, need to do over again, not only directly affects output, also create a large amount of heavy industrys.

Summary of the invention

The purpose of this utility model is to provide a kind of binding post, can be fixedly welded on above pcb board by binding post, can not produce the phenomenon of failure welding and loose contact to solve.

The utility model provides a kind of binding post in order to achieve the above object, comprise binding post body, described binding post body is provided with wiring hole, the first screwed hole and the second screwed hole, described wiring hole is arranged on binding post body one end, first screwed hole is arranged on binding post body side, and the second screwed hole is arranged on the other end of binding post body.

Preferably, the diameter of described wiring hole is the circular hole of 4mm.

Preferably, described second screwed hole diameter is the circular hole of 3mm.

Preferably, the cylinder on described binding post body is square body or cylinder.

The beneficial effects of the utility model:

1. binding post described in the utility model is installed simple, fastening firm;

2. when welding, the phenomenon that can not produce rosin joint or loose contact occurs, and directly decreases because welding not in place and loose contact that is that produce;

3. use the binding post after improving, directly can increase the output of product, avoid the generation of a large amount of heavy industry phenomenon in addition, serve and save time, reduce the benefits such as business finance expenditure.

Embodiment

For the ease of the understanding of those skilled in the art, be further described the utility model below in conjunction with embodiment and accompanying drawing, the content that execution mode is mentioned is not to restriction of the present utility model.

With reference to shown in Fig. 1, a kind of binding post, comprise binding post body 11, described binding post body 11 is provided with wiring hole 1, first screwed hole 2 and the second screwed hole 3, described wiring hole 1 is arranged on binding post body 11 one end, first screwed hole 2 is arranged on binding post body 11 side, and the second screwed hole 3 is arranged on the other end of binding post body 11.

The diameter of described wiring hole 1 is the circular hole of 4mm.

Described second screwed hole 3 diameter is the circular hole of 3mm rice.

Cylinder on described binding post body 11 is square body or cylinder.

Respectively each structure is described in detail below:

Wiring hole 1: described wiring hole 1 is arranged on one end of binding post body 11, the diameter of described wiring hole 1 is the circular hole of 4mm, and effect facilitates user to access wire, and the aperture of described wiring hole 1 is larger, facilitates threading;

First screwed hole 2: described first screwed hole 2 is arranged on the side of binding post body 11, the diameter of its first screwed hole 2 is the circular hole of 3mm, effect be for the wiring hole 1 that is fixed and clamped inside wire, by screw, the wire inside wiring hole 1 is fixed;

Second screwed hole 3: described second screwed hole 3 is arranged on the other end of binding post body 11, the diameter of its second screwed hole 3 is the circular hole of 3mm, described second screwed hole 3 is fixedly docked to the circular hole of circuit board top, effect is when not needing other mechanism to fix, fixed by screw tightening, fixing, binding post body 11 is welded to circuit board top, completes the welding job that pairs of posts body 11 docks with circuit board.

The utility model second screwed hole schematic diagram described in Fig. 2.

Fig. 4 illustrates at first technology binding post structure schematic diagram.

With reference to the utility model binding post soldered circuit board schematic diagram described in Fig. 3; Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:

The present embodiment provides a kind of binding post, it is made up of wiring hole 1, first screwed hole 2 and the second screwed hole 3, the utility model makes technological improvement mainly for the second screwed hole 3, in actual applications, above the circular hole in the face on circuit boards of the second screwed hole 3 fixed placement on binding post body 11, be screwed and tighten, after binding post body 11 is fixedly tightened, fixing again binding post body 11 being welded to circuit board top, effectively preventing because welding not in place and generation that the is phenomenon such as the rosin joint that produces or loose contact.

Embody rule approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
