Abstract
The utility model relates to a DC plug, comprising a tubular outer terminal, an inner terminal arranged at the center of the inner part of the DC plug and an insulating material layer separating the inner and outer terminals. The naked end of the inner side of the inner terminal forms a U-shaped sheet of which the inner part forms a slot channel in which one end of the wire is arranged, and the two side faces of the U-shaped sheet clamp and press the wire arranged in the U-shaped sheet. Therefore, the DC plug has good electricity conduction, raises the quality of the working environment and also can raise the tensile strength of the wire, and the wire can not fall away.
Description
Technical field
The utility model relates to a kind of DC plug, and it mainly allows the structure that wire rod stretches in the inboard exposed end formation one of inner terminal, and the affixed mode between inner terminal and wire rod is modified to the DC plug of riveting structure.
Background technology
Press, DC plug 10 comprises: outer surface becomes the external terminal 11 of tubular, is located at the inner terminal 12 of inside center, and the insulating material 13 of separating inside and outside terminal, as shown in Figure 1, the inner 14 of this inner terminal 12 forms sheet, and wire rod 15 directly is welded on inner 14 places of sheet of this inner terminal 12.During welding, this wire rod 15 is to abut on sheet the inner 14 of terminal 12 and solid welding; This tin material 16 forms the medium that is connected of wire rods 15 and 12 of inner terminals, causes tin material 16 also to become electric signal transmission conductor; Because the electrically conducting of tin material 16, causes the electrically conducting reduction after the welding less than wire rod 15.
When wire rod 15 is done welding job with sheet the inner 14 of this inner terminal 12, can in operational environment, produce high temperature, and the volatilization gas that produces the tin material, staff's operational environment quality is reduced, and staff's meeting is because of the long-time stanniferous gas that sucks, and generation occupational disease (injury); Again, the high temperature that is produced during welding causes insulating material 13 embrittlement of plug easily, forms faulty materials.
The sheet of this inner terminal 12 inner 14 is to rely on the tin material 16 of electric welding to produce the structure that is connected with wire rod 15, and its structural capacity is poor, and hot strength is low, causes wire rod 15 to come off easily, forms defective products.
Summary of the invention
The purpose of this utility model provides a kind of DC plug, but mainly at the structure that the inboard exposed end of inner terminal is formed a cramping wire rod, make combining between inner terminal and wire rod, change over the riveting mode, to improve the electric property of product by traditional welding manner.
The utility model provides a kind of DC plug, the external terminal that comprises a tubular, one is located at the inner terminal of inside center, and the insulation material layer of separating inside and outside terminal, it is characterized in that: the inboard exposed end of this inner terminal is to form a U-shaped sheet, the formed conduit in the inside of this U-shaped sheet is inserted for an end of wire rod, and the two sides of this U-shaped sheet produce cramping to the wire rod of inserting in it.
The utility model provides a kind of DC plug, and the bottom surface of this U-shaped sheet inside is provided with the horizontal raised line that at least one and the inner formed conduit of this U-shaped sheet are the orthogonal shape.
The utility model makes that its electrically conducting is preferable, makes the operational environment quality-improving, can also improve the hot strength to wire rod, and wire rod can not come off.

Embodiment
The applicant is for fear of DC plug taking place when making, because of welding wire causes product bad, and to the negative effect of operational environment, and provide the utility model content, can improve product fine, and the staff is worked under the environment in harmless health Jiankang, useful body and mind.
Now enumerate embodiment, and cooperate graphicly, structural feature of the present utility model and effect are described in detail in detail.
The DC plug that the utility model disclosed sees also Fig. 2,3, and this DC plug 20 comprises: the external terminal 21 of tubular, be located at the inner terminal 22 of inside center, and the insulating material 23 of separating inside and outside terminal.Wherein, this external terminal 21 is naked dewiness attitude, and the connected mode of itself and wire rod (not shown on the figure) has a variety of, and except the most traditional welding manner, the existing existing mode of riveted joint one garter spring (not shown on the figure) that adopts is as the structure of riveting wire rod.This is known techniques and non-genus technical characterictic of the present utility model, therefore followingly will repeat no more its detailed formation.
The inner of above-mentioned inner terminal 22 is to form a U-shaped sheet 24, and the bottom of this U-shaped sheet is to be connected with inner terminal 22 with a connecting piece 25.These U-shaped sheet 24 inner conduits 241 that form are that the exposed end 31 of allowing a wire rod 30 inserts.Again two lateral plates of this U-shaped sheet 24 are lived the exposed end 31 of this wire rod 30 with inside riveting mode cramping, and the exposed end 31 of this wire rod 30 is fixed in the U-shaped sheet 24 of this inner terminal 22, see Fig. 4,5.
The exposed end 31 of above-mentioned wire rod 30 is to be copper cash, its with 24 of the U-shaped sheets of inner terminal 22 for directly to contact, and contact area is bigger, then the electronic impedance of contact point is lower, its electric property naturally tradition be good with the welding manner connectionist.
Bottom surface in the U-shaped sheet 24 of above-mentioned inner terminal 22 is a flat condition, and this bottom surface is provided with the horizontal raised line 242 of at least one.This horizontal raised line 242 is to be the orthogonal shape with these U-shaped sheet 24 inner formed conduits 241.Wire rod 30 exposed ends 31 of 242 pairs of rivetings of this raised line in this U-shaped sheet 24 can produce anti-avulsion, and the structural strength after improving this U-shaped sheet 24 and wire rod 30 combining makes the quality of product more good.
22 of above-mentioned wire rod 30 and inner terminals, owing to do not do welding operation, so be not subjected to high-temperature baking, then the thing of embrittlement can not take place in this insulating material 23, can reduce the fraction defective of product.Again, because the working site do not need to do high-temperature soldering work, make the factory building internal temperature comparatively normal, also stanniferous not in the air makes the operational environment quality-improving of factory building, and the occupational disease of relevant high-temperature soldering also can not take place the staff.
The inner terminal of DC plug provided by the utility model and the syndeton between wire rod, it is connected employing riveting structure at wire rod 30 with inner terminal 22, both can improve the quality of product, can improve the environmental quality of workplace again, real two designs that get at one stroke.
The above is to utilize preferred embodiment to describe the utility model in detail, and unrestricted scope of the present utility model.Allly know this type of skill personage and all can understand, suitably do some and change and adjust, will not lose main idea of the present utility model place, also do not break away from the spirit and scope of this practical utility model.
In sum, the specifics that the utility model is implemented, your auditor the sincere utility model patent important document that has met defined in the Patent Law please grant quasi patent.
