Description

Bayonet connector

The utility model relates to a kind of bayonet connector, refers in particular to a kind ofly can be directly applied for different operating voltage and specification demand, and for the universal bayonet connector of correct winding sub-circuit board.

Because the development of electronic installation is rapid, makes new product and new function constantly weed out the old and bring forth the new, and is example with the computer, under the various situation of product and functional type, its inner motherboard can not be contained all functions fully.In addition, different clients has different demands usually, makes motherboard to carry out the telecommunication transmission by the integrated circuit board shape sub-circuit board of setting up as display card, network interface card etc. under in response to various functional demands, to increase the function that whole device can be reached.Several bayonet connectors are set on motherboard usually pegs graft for the sub-circuit board of specific standard; yet the sub-circuit board of various difference in functionalitys will have the demand of different operating voltage in design; therefore for avoiding the wrong plug position to cause short circuit or damage; on the bayonet connector slot of joining with its district, can be provided with usually and prevent the key position design that misplugs; be used for avoiding mispluging and guaranteeing life of product; yet different key positions is provided with and will causes same type products to have plurality of specifications to occur; this not only makes troubles to production management, has also increased the weight of the burden that motherboard manufacturer gets the raw materials ready.So in the design of existing bayonet connector, utilize an activity conversion key, be inserted on the predetermined key position of bayonet connector insulator, bayonet connector only can be inserted for the sub-circuit board that is provided with the breach that is complementary with respect to this particular key position, so the position that further makes this bayonet connector can adjust its conversion key cooperates the sub-circuit board of different operating voltage requirements, to improve the versatility of same type bayonet connector.Yet whether conversion key is plugged on the accurate location, also can't confirm before sub-circuit board inserts, and so will influence winding efficient and and the electrical stability in contact of motherboard between sub-circuit board and bayonet connector.At present, at United States Patent (USP) the 5th, 366,382,4,106, cases such as No. 481 disclose to have utilizes switch terminal to produce the switch signal so that the discriminating function of certain degree to be provided, see also Figure 1 and Figure 2, be relatively set with switch terminal 91 on insulator 90 dual-sides of bayonet connector, and by its terminal set elastic arm 92 mutually overlap joint form and electrically conduct, in case after sub-circuit board (not shown) group places slot 93, the elastic arm 92 of two relative switch terminals 91 can be backed down and form and open circuit.Yet this kind design is only reached the switch effect by the overlap joint of switch terminal 91 terminal elastic arm 92 point-like contacts, have slightly rock or the situation of terminal slight deformation under promptly can cause the conducting of switch terminal or disconnect and all be in utmost point unsure state, and then can't correctly learn identification result.In addition, these terminals need have the higher accuracy of manufacture, otherwise terminal after assembling the accurately phenomenon of contraposition will take place owing to be subjected to the influence of mismachining tolerance when the processing assembling, and then have increased production cost.

One of the utility model purpose is to provide a kind of bayonet connector, this bayonet connector is provided with the conducting element of two different contact-making surfaces at least, to form bigger contact area between this conducting element and switch terminal, and terminal can keep bigger elasticity surplus realizing infallible electrically conducting, and reduces switch terminal the requirement of processing assembly precision is saved production cost.

Two of the utility model purpose is to provide a kind of bayonet connector, this bayonet connector is inserted between the set paired switch terminal of ad-hoc location by identification key movably, with before sub-circuit board is connected to bayonet connector, the electric connection state that changes the switch terminal of this ad-hoc location is in advance judged suitable or predetermined voltage and switched the phenomenon of the circuit that can not be damaged with the smooth winding of the sub-circuit board that this different size is provided.

The purpose of this utility model is achieved through the following technical solutions: bayonet connector includes insulator, signal terminal, switch terminal, structures such as conducting element and movable identification key, wherein the central part place, a side of insulator is concaved with lengthwise shape slot, this slot is surrounded by the two side, this two side is provided with several through holes that runs through sidewall along being parallel to the recessed direction of slot, several signal terminals promptly are contained in it respectively, and switch terminal set places in the through hole of the more than one privileged site of insulator, and the side that these privileged sites rely on the sub-circuit board direction of insertion is formed with recess, and the identification key can selectivity be solidly plugged in the recess of ad-hoc location according to the actual demand of sub-circuit board operating voltage, have only the sub-circuit board that is fit to this voltage specification can peg graft on it with restriction, in addition, insulator is provided with the groove that is used for accommodating conducting element with respect to the opposite side position that recess is provided with the side, it can make switch terminal set on the relative position just be positioned at these conducting element both sides and elasticity is conflicted thereon, and reach infallible electrically conducting, make the identification key be inserted in one of these ad-hoc locations afterwards again, make the switch terminal at this place become off-state, produce the effect of identification operating voltage by conducting state.

According to above-mentioned principal character, the switch terminal of this bayonet connector has the principal part that is posted by insulator through-hole wall face, this principal part extends emergence to insulator and the formation weld part towards an end of motherboard, its relative other end then oppositely bends and extends to form the arcuation kink simultaneously, the extending end of this arcuation kink earlier with special angle curved incline to extending then be parallel to principal part and extend to form elastic arm, the terminal appropriateness of this elastic arm is goed deep in the groove of insulator and is formed the cambered surface abutting part that contacts on the conducting element.

Owing to adopted such scheme, the utility model can effectively prevent mispluging of sub-circuit board, and the effect that before sub-circuit board is planted, promptly has switching and identification operating voltage, and the state that electrically conducts between the switch terminal that electrically connects mutually is infallible, and it can reduce the requirement to the accuracy of manufacture, thereby saves production cost.
