Abstract

The utility model relates to an improved contact probe which comprises a thimble, a sleeve post, a spring and a stopper, wherein one end of the thimble is in contact with the spring and a column lateral surface part of the thimble is embedded into the inner part of the sleeve post. In addition, the spring is arranged at the inner part of the sleeve post and the other end of the spring is in contact with the stopper. The stopper has a lug boss structure, and a lug boss is plugged in the sleeve post. The parts of the improved contact probe are the thimble and the stopper, and an extrusion method in extrusion forming is a line extrusion method. Compared with a conventional probe, the utility model has obvious progress and has the advantages of quick finished product production and easy assembly.

Description

The improvement contact probe

Technical field

The utility model relates to a kind of improvement contact probe, be meant especially a kind of when being used for contacting with battery, as the contact probe of contact.

Background technology

At present, general Portable electrical equipment, for example mobile phone, walkman, recorder, digital camera or the like all can have the installation battery, have plenty of rechargeable battery, have plenty of the battery of general standard.Usually having a position on Portable electrical equipment can be for placing various batteries.And this position has a contact usually, is connected with the positive and negative polarities of battery.Early stage contact is a shell fragment, but can be tired after the permanent use of the elasticity of shell fragment, therefore, has the people contact to be improved to the contact of probe-type.

Fig. 1 is probe-type contact commonly used.Probe mainly is made up of four assemblies, is respectively thimble 11, sleeve column 12, spring 24 and lid 13.Probe thimble 11 and lid 13 materials commonly used are brass, and lid 13 is the columnar structured of medial recess, adopt the mode of machined into to finish during making, yet the speed of machined into are very slow, and it is on the low side to make production efficiency.In addition, lid 13 is adopted the mode that covers with the combination of sleeve column 12, is not easy assembling.Fig. 2 is another kind of probe-type contact commonly used, its structure is with the different of Fig. 1, the lid 13 of Fig. 1 and sleeve column 12 one-body molded be a barrel mast 15, thimble 11 is partly then many protuberance 111 is used for stretching in the spring 24, earlier protuberance 111 is put into spring 24 during assembling, put into barrel mast 15 again, use processing method afterwards again, the edge 121 of barrel mast is inwardly pressed, block thimble 11, thimble can not run out.This manufacture method, processing is trouble quite, and the contraposition of thimble and spring (very tiny) is quite painstaking, poor efficiency.

The utility model content

The purpose of this utility model is to provide a kind of improvement contact probe, and its make efficiency improves and the assembling facility.

For solving the problems of the technologies described above, technical scheme provided by the utility model is:

The improvement contact probe comprises a thimble, a sleeve column, a spring and a stopper, and an end of thimble contacts with spring, and the cylindrical side of thimble partly embeds this sleeve column inside, and in addition, spring is located at sleeve column inside, and the other end of spring then contacts with stopper; And described stopper has boss structure, and boss is filled within the sleeve column.The part of improvement contact probe such as thimble, stopper, extrusion molding, described extrusion forming method are the line pressing method.

Adopt said structure because stopper is filled in sleeve column withstands spring and make that thimble can retraction owing to being pressed, and stretch out during pressure relief, stopper has boss structure, and the material of this thimble and this stopper is an oxygen-free copper, can utilize pressing method one-body molded, thereby reach the time purpose of quickening to make thimble and stopper.In sum, it is quick that this case improvement contact probe can produce into product, and assembling is easy to advantage, obviously than the probe progress of commonly using.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and embodiments:

Fig. 1 is contact probe schematic diagram commonly used;

Fig. 2 is another contact probe schematic diagram commonly used;

Fig. 3 is the improvement contact probe schematic diagram of the utility model preferred embodiment.

Symbol description:

21 thimbles, 22 sleeve columns

23 stoppers, 24 springs

25 waists, 11 thimbles

12 sleeve columns, 13 lids

15 bobbins, 111 protuberances

121 edges

Embodiment

See also Fig. 3.Improvement contact probe of the present utility model mainly is made up of thimble 21, sleeve column 22, spring 24 and stopper 23; One of thimble 21 end contacts with spring 24, and the cylindrical side of thimble 21 partly embeds and entangles within 22; In addition, spring 24 is located within the sleeve column 22, and the other end of spring then contacts with stopper 23, and stopper has boss structure; Stopper 23 is then filled within the sleeve column 22.The thimble 21 of this case and the material of stopper 23 are oxygen-free copper, the composition 99.9% of copper, and the mode of available line extruding is made, and the lathe that its speed ratio of making production is commonly used is many soon, can greatly promote the usefulness of production.The utility model and difference commonly used are, the structural design of stopper 23.Utilize stopper 23 to withstand spring, can ease of assembly, on production cost, also can greatly lower., when assembling, can snap in very easily above the pedestal in the place of waist 25, can fix after snapping in, more more progressive than the practice of commonly using.

Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or variation, therefore, all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.

Claims

1, a kind of improvement contact probe comprises a thimble, a sleeve column, a spring and a stopper, it is characterized in that: an end of described thimble contacts with spring, and the cylindrical side of thimble partly embeds sleeve column inside; In addition, spring (24) is located at sleeve column inside, and the other end of spring then contacts with stopper; And described stopper has boss structure, and boss is filled within the sleeve column.
