Goal of the invention：In order to overcome the deficiencies in the prior art, when the utility model, which provides one kind, can prevent bonding wire The closed terminal that solder overflow occurs.

Technical solution：To achieve the above object, the closed terminal of the utility model includes insulating body, the insulation base Body is equipped with multiple rectangular jointing holes, and metal terminal is both provided in each jointing holes；The metal terminal, which has, is placed in institute The terminals held and stretched out in except the jointing holes that patch in jointing holes are stated, the end that patches has for external terminal The U-shaped main part being inserted into, on the direction that external terminal enters, the opening of U-shaped main part first narrows from the width, again by narrow change Width, and the oral area of U-shaped main part has elasticity.

Further, two symmetrical elastic pressuring plate groups that the U-shaped main part is extended by substrate and by substrate At the middle and lower part of the elastic pressuring plate is connected on substrate, and the top of elastic pressuring plate has the mouth that elasticity constitutes U-shaped main part Portion, and the lower part of two elastic pressuring plates bends inwards to the bottom for constituting U-shaped main part that contacts with each other.

Further, the substrate has the extension extended to the oral area of U-shaped main part.

Further, a lateral deviation with elastic pressuring plate of the terminals relative to the substrate-parallel and to substrate It moves, by oblique angle transition between substrate and terminals.

Further, end and the terminals of patching are integrally formed part.

Further, the metal terminal is made of copper alloy.

Further, the material of the insulating body is polyester.

Further, one end of the oral area corresponding to U-shaped main part of the jointing holes is provided with horn mouth.

Further, including on insulating body there are two rows of jointing holes, often arrange there are six jointing holes.

Advantageous effect：The metal terminal of the closed terminal of the utility model has U-shaped main part, U-shaped main part Lower end closed, effectively terminals and jointing holes are kept apart, scolding tin can be effectively prevent to spill into inside jointing holes, can be carried significantly High finished product rate.

Description of the drawings

Attached drawing 1 is the front view of closed terminal；

Attached drawing 2 is the side sectional view of closed terminal；

Attached drawing 3 is the vertical view of closed terminal.

Specific implementation mode

The utility model is further described below in conjunction with the accompanying drawings.

Closed terminal as illustrated in the accompanying drawings from 1 to 3, including insulating body 1, the insulating body 1 are equipped with multiple rectangular Jointing holes 11 are both provided with metal terminal 2 in each jointing holes 11；The metal terminal 2, which has, to be placed in the jointing holes 11 Patch end 21 and stretch out in terminals 22 except the jointing holes 11, it is described patch end 21 and have inserted for external terminal The U-shaped main part entered, on the direction that external terminal enters, the opening of U-shaped main part first narrows from the width, again by narrow change Width, and the oral area of U-shaped main part has elasticity.This structure can guarantee that metal terminal 2 comes into full contact with external terminal.

Two symmetrical 212 groups of elastic pressuring plates that the U-shaped main part is extended by substrate 211 and by substrate 211 At the middle and lower part of the elastic pressuring plate 212 is connected on substrate 211, and there is elasticity to constitute U-shaped master on the top of elastic pressuring plate 212 The oral area of body portion, and the lower part of two elastic pressuring plates 212 bends inwards to the bottom for constituting U-shaped main part that contacts with each other.

The substrate 211 has the extension 213 extended to the oral area of U-shaped main part.

The end 21 that patches is integrally formed part with terminals 22, at low cost.The terminals 22 are relative to the substrate 211 is parallel and deviated to side of the substrate 211 with elastic pressuring plate 212, by oblique angle 214 between substrate 211 and terminals 22 Transition.

The metal terminal 2 is made of copper alloy.

The material of the insulating body 1 is polyester.

External terminal is inserted into jointing holes 11 for convenience, the oral area corresponding to U-shaped main part of the jointing holes 11 One end be provided with horn mouth 12, horn mouth 12 has guiding role.

Including having two rows of jointing holes 11 on insulating body 1, often arrange there are six jointing holes 11.

The metal terminal of the closed terminal of the utility model has U-shaped main part, the lower end seal of U-shaped main part It closes, effectively keeps apart terminals and jointing holes, scolding tin can be effectively prevent to spill into inside jointing holes, be greatly improved finished product Rate.

The above is only the preferred embodiment of the utility model, it should be pointed out that：For the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the scope of protection of the utility model.
