Description

The loud speaker connector

Technical field

The utility model relates to a kind of connector, relates in particular to a kind of loud speaker connector.

Background technology

In recent years, consumption electronic products such as mobile phone, PDA, MP3, notebook computer have obtained using widely, have loud speaker on these consumption electronic products usually to sound.Loud speaker on the consumption electronic product is to electrically connect the function that realizes that it is sounded by the circuit board on a loud speaker connector and the consumption electronic product.

Traditional loud speaker connector generally adopts the mode of welding that conducting terminal is welded on the circuit board, and therefore after being welded on the loud speaker connector on the circuit board, in the time of need doing over again, the loud speaker connector is difficult for disassembling from circuit board; And the also inconvenient second use of the loud speaker connector that disassembles, thus cause waste, and along with the increase of service time, the scolding tin joint of the conducting terminal of loud speaker connector easily with the circuit board disengaging, thereby cause electric loose contact.

The utility model content

The purpose of this utility model is a kind of electric contact stabilization to be provided, to be convenient to dismantle and be convenient to the loud speaker connector of second use at the defective that exists in the above-mentioned background technology.

To achieve these goals, the utility model loud speaker connector comprises insulating body and at least two conducting terminals.Described insulating body has a pedestal, and pedestal has bottom surface and end face, and the middle part of the end face of this pedestal offers a groove downwards, and the both sides of the diapire of groove offer the terminal groove that runs through this insulating body downwards; Described conducting terminal have one be vertically tabular holding parts, one by the upper end edge of holding parts to a lateral buckling extend again elastic compression portion that oppositely bending extends to form, by a side of this elastic compression portion along one first contact site that extends outward, an elastic portion that is back and forth bending and terminal extended second contact site downwards by elastic portion that a lower end edge by holding parts extends out; Holding parts and elastic portion place in the terminal groove of insulating body, second contact site protrudes out outside the insulating body downwards, elastic compression is deployed in the groove of insulating body, the end of first contact site upwards bending is bent to form one first contact head downwards, and this first contact head protrudes upward outside the insulating body.

As mentioned above, the utility model loud speaker connector is that the elastic force that first contact site and the elastic portion by conducting terminal provides guarantees that conducting terminal is in firm elasticity butt state with two circuit boards all the time, and then guarantees the reliable transmission of electric signal between two circuit boards; And this loud speaker connector adopts the mode of direct elasticity conflict circuit board to assemble, and needn't fix by scolding tin, thereby the assembling of the utility model loud speaker connector simply and easily disassembles from circuit board, also is convenient to second use after pulling down, thereby economizes on resources.

Embodiment

By describing technology contents of the present utility model, structural feature in detail, being reached purpose and effect, below in conjunction with embodiment and cooperate graphic detailed description the in detail.

See also Fig. 1, the utility model loud speaker connector 1 comprises an insulating body 10 and two conducting terminals 20.

See also Fig. 1, Fig. 2 and Fig. 4, insulating body 10 has a pedestal 11 that roughly is cylindrical shape.The bottom surface of pedestal 11 is extended two fins 12 that are flat column downwards.The end face of pedestal 11 is an inclined plane, and this end face extends upward the projection 13 of four symmetric arrays.The middle part of the end face of this pedestal 11 offers a groove 111 downwards.The both sides of groove 111 diapires offer the terminal groove 112 that runs through pedestal 11 and fin 12 downwards.Between two ends pilot trench 112, the diapire of groove 111 extends upward a boss 113, and the end face of this boss 113 offers two draw-in grooves 114 downwards.Fin 12 lower ends protrude out one and keep out arm 121 in terminal groove 112.

Please consult Fig. 2 again, conducting terminal 20 comprises that one is vertically tabular holding parts 21.The upper end edge of holding parts 21 extends to form one to the reverse again bending of lateral buckling extension and is " the elastic compression portion 22 of U ＂ shape.The front end edge of elastic compression portion 22 bending downwards extends a buckle 23, and the terminal outwards bending on a side edge of this elastic compression portion 22 is extended with one first contact site 24.The end of first contact site 24 upwards bending is bent to form first contact head 241 downwards.

The lower end edge of holding parts 21 bends back and forth and is extended with an elastic portion 25.The lower end edge of elastic portion 25 ends extends downwards and is the second tabular contact site 26 of bar.The end of this second contact site 26 forms the second curved contact head 261.

See also Fig. 2 and Fig. 3, in the holding parts 21 of conducting terminal 20 and the elastic portion 25 insertion end pilot trench 112, the end of elastic portion 25 is pressed on keeping out on the arm 121 of fin 12, second contact head 261 of second contact site 26 in terminal groove 112, protrude out outside the fin 12 with the circuit board (not shown) butt of an electronic product.Elastic compression portion 22 places in the groove 111, and the bottom of this elastic compression portion 22 is connected on the diapire of groove 111, and the top of this elastic compression portion 22 is connected on the boss 113, and buckle 23 is stuck in the draw-in groove 114.The top that first contact head 241 of first contact site 24 is positioned at pedestal 11 end faces with loud speaker on the circuit board butt.

In sum, the utility model loud speaker connector 1 is by first contact head 241 of conducting terminal 20 and the circuit board elasticity butt on the loud speaker, the circuit board butt of second contact head 261 and electronic product, thereby the signal of telecommunication of reaching between two circuit boards connects, first contact site 24 of conducting terminal 20 and the elastic force that elastic portion 25 provides guarantee that conducting terminal 20 is in firm elasticity butt state with two circuit boards all the time, and then guarantee the reliable transmission of the signal of telecommunication between two circuit boards.This loud speaker connector adopts the mode of direct elasticity conflict circuit board to assemble, and needn't fix by scolding tin, therefore the assembling of the utility model loud speaker connector 1 is simple, and dismounting easily between this loud speaker connector 1 and the circuit board, thereby can not change whole loud speaker connector 1, and then reach the effect that reduces cost because of the inefficacy of individual elements.
