Abstract
The utility model provides an improved structure of spring terminal connector. The spring terminal connector is composed of a metal casting, a thimble, and a spring, and the thimble and the spring is in the containing space of the metal casting. The top end of the metal casting is provided with a hatch, and the thimble can move elastically in the containing space through the action of the card-blocking apparatus of the hatch and the spring. The containing space extends downwards and shrinks inwards gradually to a cone-type guide hole penetrating the bottom in the base, so the welding strength of the electric connector is effectively increased, and the time of the electric welding producing process is shortened.
Description
Technical field
The utility model relates to a kind of structure-improved of spring terminal connector, especially about a kind of spring terminal electric connector that has the taper guide hole at base.
Background technology
The spring terminal connector of Chu Xianing in the market, generally constituted by sleeve pipe, spring and thimble, sleeve pipe is generally hollow sleeve, and thimble places inside pipe casing, and general sleeve pipe leading section has the block that prevents that thimble from deviating from usually, spring then places inside pipe casing, and contact with the thimble rearward end, by setting by spring, thimble can be in spring range limited moving, and make thimble become a preferable couple state with the terminal that docks, with the effect that guarantees electrically to transmit.
Existing spring terminal connector, be provided with a base in the sleeve pipe rear end, with the closed casing open rearward end, with support spring and thimble, this base is the physical plane, when the compression joint type electric connector is soldered to circuit board, can influence the firm stable of whole electric connector and circuit board because of the physical plane welding effect.
For this reason, industry is real to be necessary this kind spring terminal connector is carried out improvement design, and this electric connector produces for the electric connection that adapts to better realization mobile communication.
The utility model content
Main purpose of the present utility model is to provide a kind of structure-improved of spring terminal connector, and it utilizes the full taper guide hole that belongs to the case bottom, makes the utility model when electroplating, and can rapidly unnecessary electrolyte and other impurity be discharged.
Another purpose of the present utility model is to provide a kind of structure-improved of spring terminal connector, and it utilizes the taper guide hole of metal case bottom, in order to strengthen welding effect, makes this electric connector firmly be connected to circuit board, smooth transport electric power.
By above-mentioned all purposes as can be known the architectural feature of the utility model creation be: this spring terminal connector then is by the metal case, thimble and spring are formed, wherein the thimble Lower Half is provided with a protruding ring around the thimble periphery, metal case center has an accommodation space, suitable can ccontaining thimble, and can be for thimble in wherein sliding, this accommodation space runs through metal case top and becomes an opening, the harvest one in the center of this opening is closed up, this closing in and thimble Lower Half convex to form block, prevent that thimble from being deviate from by opening part, spring is inserted in the accommodation space and end in contact behind the thimble, be the contact effect of increase spring with thimble, this thimble is provided with a hollow bulb and runs through the bottom, make spring stretch into hollow bulb and have good contact effect with thimble, and function with fixing spring top, accommodation space extends downwards, and base gradually in harvest one run through the taper guide hole of bottom, the skew wall of this taper guide hole is in order to the lower end of support spring, thimble can limitedly be moved in the metal case, by by thimble, spring and metal case effectively electrically connect the utility model.
The setting of this taper guide hole provides more scolding tin contact-making surface and soldering tin amount when the welding of metal case and circuit board, promote the welding steadiness of electric connector and circuit board.
And this taper guide hole provides a passage, makes the utility model remain in the electroplate liquid and the impurity of hollow bulb when electroplating, and can be discharged rapidly by this taper guide hole, and reduce the flow process time, improves the product yield.
Be familiar with this operator and can understand structural feature of the present utility model really for making, and other creation purpose and effects, now lift specific embodiment, after cooperating appended graphic being described in more detail in, the usefulness that only selected embodiment only illustrates for the utility model, the utility model still can otherwise be implemented, so being familiar with this operator is not breaking away under the creation spirit of the present utility model, Fan Yiben explanation and can make other change and implement aspects, all can be contained by the utility model claim.

Embodiment
Please refer to Fig. 1 to Fig. 4, the utility model spring terminal connector is by metal case 1, thimble 2 and spring 3 are formed, wherein thimble 2 Lower Halves are provided with a projection 22 around thimble 2 peripheries, metal case 1 center has an accommodation space 11, suitable can ccontaining thimble 2, and can be for thimble 2 in wherein sliding, this accommodation space 11 runs through metal case 1 top and becomes one to open 12, the harvest one in the center of this opening 12 closes up 13, this closing in 13 forms blocks with thimble 2 Lower Halves projection 22, prevent that thimble 2 from being deviate from by opening 12 places, spring 3 is inserted in the accommodation space 11 and thimble 2 back end in contact, be the contact effect of increase spring 3 with thimble 2, this thimble 2 is long shell-like hollow housing, and being provided with a hollow bulb 21 runs through the bottom, and its bottom opening is convex, be placed in closing in place of metal case 1, thimble 2 can carry out free-piston type motion within it, and the strain by spring 3 closely connects battery.Make spring 3 can stretch into hollow bulb 21 and have good contact effect with thimble 2, and function with fixing spring 3 tops, accommodation space 11 extends downwards, and base 14 gradually in harvest one run through the taper guide hole 15 of bottom, the skew wall 151 of this taper guide hole 15 is in order to the lower end of support spring 3, thimble 2 can limitedly be moved in metal case 1,, the utility model is effectively electrically connected by by thimble 2, spring 3 and metal case 1.
The setting of this taper guide hole 15 provides more scolding tin contact-making surface and soldering tin amount at metal case 1 during with the circuit board welding, promotes the welding steadiness of electric connector and circuit board.
And this taper guide hole 15 provides a passage, makes the utility model remain in the electroplate liquid and the impurity of hollow bulb 11 when electroplating, and can be discharged rapidly by this taper guide hole 15, and reduce the flow process time, improves the product yield.
Explanation as can be known from the above mentioned, the new structural design of the utility model utilization had more in the past the compression joint type electric connector to present better use effect on the like product, shorten the flow process time of making simultaneously, reduce the complexity of assembly working, so the utility model possesses novel patent requirement really.
