Description

The terminal of bayonet connector and bayonet connector

Technical field

The utility model relates to a kind of conducting terminal, particularly relates to a kind of terminal of bayonet connector.

Background technology

General electronic cards, for example each table is from generation to generation gone up and is reached portable computer memory modules (MemoryModules), network communication card module, multimedia video module and satellite positioning module (GPS Modules), central processing unit, compiling decoder etc., must be electrically connected with circuit board by at least one or a plurality of bayonet connector.

If when the terminal of existing bayonet connector is made with the bending forming mode, because of terminal does not have burr, make terminal not have scraping (wiping) effect when contacting with the conducting strip of electronic cards, conductivity is relatively poor.In order to improve foregoing problems, the solution in a scraping district is established on the contact site surface that novel M348346 patent is provided at terminal in Taiwan, conducting strip by this scraping district scraping electronic cards, hinder oxide, barrier layer or the pollutant of conductivity to remove the conducting strip surface, increase the conductivity between electronic cards and the terminal.

Yet, in the specific embodiment of terminal that this patent discloses, scraping district can generally be divided into two classes, and a class is that the length direction along contact site forward extends, for example shown in Figure 1, the scraping district 91 of terminal 9 is the raised lines that extend and protrude contact site 92 surfaces along contact site 92 length directions; Another kind of is length direction horizontally set along contact site, for example shown in Figure 2, and the scraping district 91 ' of terminal 9 ' is the transverse concave groove that plural number is arranged along contact site 92 ' length direction at intervals.Though wherein there is the scraping effect in the scraping district 91 of forward extending, but it is still remarkable inadequately, though and there is significant scraping effect in the scraping district 91 ' of horizontally set, but the transverse concave groove in scraping district 91 ' is vertical with the direction of insertion of electronic cards, block the edge clipping of electronic cards easily, hinder electronic cards to move, and because the edge clipping of electronic cards is stuck in the groove, make that terminal continues to be under pressure, cause the terminal distortion easily.

So how to make terminal have better scraping effect, and can not cause the terminal distortion, also have improved space.

The utility model content

A purpose of the present utility model is that a kind of terminal that has better scraping effect and can not cause the bayonet connector of terminal distortion is being provided.

Another purpose of the present utility model is that a kind of bayonet connector with aforementioned terminal is being provided.

The terminal of bayonet connector of the present utility model, comprise: the elastic arm that the junction that a fixed part, is extended by an end of this fixed part, is extended by the other end of this fixed part, an and contact site that is connected in this elastic arm end, this contact site is the curved arc shape, and have one in order to contact the contact-making surface of an electronic cards, this terminal also comprises and is located at least one breach that this contact-making surface is partial to this elastic arm place, and forms single order portion at least by this breach, and this rank portion has at least one salient angle.

The beneficial effects of the utility model are: by the rank portion with salient angle, can produce the scraping effect to the conducting strip of electronic cards, and breach is provided in a side of contact-making surface deflection elastic arm place, can avoids blocking the edge clipping of electronic cards, also avoid the terminal compressive deformation.

Embodiment

Below in conjunction with drawings and Examples the utility model is elaborated:

Before the utility model is described in detail, be noted that in the following description content similarly assembly is to represent with identical numbering.

Consult Fig. 3 and Fig. 4, first preferred embodiment of the terminal 1 of bayonet connector of the present utility model comprises: the elastic arm 13 that junction that a fixed part 11, is extended by the end bending of fixed part 11 12, is extended by the other end bending of fixed part 11, and a contact site 14 that is connected in elastic arm 13 ends.Contact site 14 is the curved arc shape, and has one in order to contact the contact-making surface 141 of an electronic cards 8 (consulting Fig. 6).Terminal 1 also comprises a breach 15 that is located at contact-making surface 141 deflection elastic arms 13 places, and form single order portion 16 by breach 15, the summit 140 of 16 adjacent contact portions 14 of rank portion and close elastic arm 13 sides have the salient angle 161 towards elastic arm 13, and salient angle 161 are pointed.In the present embodiment, rank portion 16 has a salient angle 161, but rank portion 16 also can have the salient angle more than two or two, for example is vv shape, does not exceed with present embodiment.

Consult Fig. 5, the terminal 1 of most basic embodiment can be assembled in an insulation shell 2 and form the bayonet connector 3 that the subcard 8 of can powering is planted.For convenience of description, Fig. 5 only illustrates down row's terminal, but the contact site of the row's of going up terminal also can be provided with the structure of breach 15 and rank portion 16 at contact-making surface.

Consult Fig. 6 and Fig. 7, when electronic cards 8 when the plant direction is inserted the slot 31 of bayonet connector 3, conducting strip 81 on the electronic cards 8 is with after contact site 14 contacts, can relatively move up to arriving location (consulting Fig. 8 and Fig. 9) with contact site 14, in electronic cards 8 moving process, rank portion 16 produces friction with conducting strip 81 surfaces, can hinder oxide, barrier layer or the pollutant of conductivity to strike off on conducting strip 81 surfaces, to increase the conductivity between conducting strip 81 and the terminal 1.And rank portion 16 is summit 140 and close elastic arm 13 sides that are positioned at adjacent contact portion 14, its salient angle 161 is towards elastic arm 13, so rank portion 16 is with respect to the plant direction of electronic cards 8, be summit 140 rear sides that are positioned at contact site 14, when rank portion 16 contacts with conducting strip 81, the edge clipping 82 of electronic cards 8 has passed through the summit 140 of contact site 14, and the direction that salient angle 161 protrudes out is the direction that moves along electronic cards 8, and can not produce the situation of the edge clipping 82 that blocks electronic cards 8, therefore can avoid terminal 1 to be subjected to undue influence and the shortcoming of being out of shape.

Consult Figure 10, second preferred embodiment and first preferred embodiment of the terminal 1 ' of bayonet connector of the present utility model are roughly the same, only, the terminal 1 ' of second preferred embodiment is to form two rank portions 16 ' by breach 15 ', and each rank portion 16 ' has a salient angle 161 ', illustrate that rank portion 16 ' also can be most, does not exceed with embodiment.
