Description
Technical Field
The utility model relates to a connector technical field, concretely relates to locking contact terminal that moves.
Background
CONNECTOR, i.e. CONNECTOR. Also known domestically as connectors, plugs and sockets. Generally referred to as an electrical connector. I.e., a device that connects two active devices, carrying a current or signal. The connector forms and structures are widely varied, and there are various types of connectors depending on the application, frequency, power, application environment, and the like. And all of the connectors that complete the circuit are the contacts, i.e., contact terminals.
The fixing mode of the existing contact terminal is mostly in a clamping mode, namely the clamping mode is adopted by widening the terminal body directly to form a barb to be clamped with the connector body, and after the plugging times of the connector assembled like this are increased, the contact terminal is easy to loosen, the service life of the connector is influenced, and therefore the improvement is needed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect and not enough, provide an anti-looseness contact terminal, have the advantage that joint stability is high, simple structure, application scope are wide.
In order to achieve the above object, the utility model adopts the following technical scheme: a loose proof contact terminal comprising: a terminal body; a spreading arm part arranged on the terminal body; and the inverted hook part is fixedly assembled on the unfolding arm part, has a gap with the terminal body and is used for enhancing the clamping stability of the terminal body.
The terminal body is provided with an elastic piece part, the elastic piece part is formed by protruding the terminal contact part on the terminal body to one side of the terminal contact surface, and the elastic piece part is used for increasing the contact degree when being connected with an external contact terminal.
The joint of the elastic piece part and the terminal body is provided with a reinforcing rib, and the reinforcing rib is used for reinforcing the elastic strength of the elastic piece part.
The terminal body the exhibition arm portion the overhead kick portion reaches behind the shell fragment portion integrated into one piece adopted above-mentioned technical scheme, the utility model discloses beneficial effect does:
1. through setting up exhibition arm portion and the overhead kick portion on the terminal body for the joint of contact terminal and connector body is more stable. When the contact terminal is inserted into the jack in the connector body, the included angle between the hook body of the inverted hook part and the hook handle is reduced, the hook body is compressed, the generated restoring force supports the contact terminal tightly in the jack, and the hook body is clamped with the inner wall of the jack, so that the contact terminal is further fixed in the jack. When external connector inserts, external connector's terminal and this locking contact terminal slides each other to exert an effort to the direction of extracting to this locking contact terminal, at this moment, collude the body and restore and with the jack wall under the effect of the frictional force, firmly block the jack inner wall, with this, make the joint of contact terminal and connector body more stable, also prolong the life-span of connector.
2. Through setting up the shell fragment portion on the terminal body for the inserted contact terminal is supported tightly under the restoring force effect that shell fragment portion produced, thereby increases the contact degree between them, avoids two connector contact failure, and influences signal transmission.
3. Through setting up in the strengthening rib of the junction of spring plate portion and terminal body for the elastic strength of strengthening rib is strengthened, so that but plug number of times promotes, thereby the mechanical life of extension connector has the advantage that joint stability is high, simple structure, application scope are wide.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Fig. 1 is a schematic structural diagram of the present invention;
description of reference numerals: 1. a terminal body; 2. stretching the arm; 3. a reverse hook part; 4. a spring piece portion; 5. and (5) reinforcing ribs.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment as required without making a contribution, but all the embodiments are protected by the patent law within the scope of the claims of the present invention.
The present embodiment relates to a loose-proof contact terminal, which is mainly applied to an I/O connector, as shown in fig. 1, and comprises: terminal body 1, exhibition arm portion 2, barb portion 3, shell fragment portion 4 and strengthening rib 5.
Wherein, exhibition arm portion 2 has two, and two 2 symmetries of exhibition arm portion set up on terminal body 1, and overhead kick portion 3 also is provided with two, and its symmetry respectively sets up on exhibition arm portion 2, and overhead kick portion 3 colludes the handle and colludes the body including colluding, and two collude the relative setting of body. And a gap exists between the terminal body 1 and the inverted hook part 3, and the clamping stability of the terminal body 1 is enhanced. Preferably, the spreading arm part 2 is perpendicular to the terminal body 1, and the barb part 3 is fixedly assembled at the end of the spreading arm part 2 and perpendicular to the spreading arm part. The terminal body 1, the arm-spreading part 2 and the barb part 3 are in a towel shape.
The spring piece portion 4 is formed by projecting the terminal contact portion on the terminal body 1 to the terminal contact surface side, and the spring piece portion 4 is used for increasing the contact degree when connecting with the contact terminal of the external connector. The principle is that when the contact terminal of the external connector is inserted, the elastic piece part 4 is compressed, and the inserted contact terminal is pressed tightly by the restoring force generated by the elastic piece part 4, so that the contact degree between the contact terminal and the elastic piece part is increased. The strengthening rib 5 is fixedly assembled at the joint of the elastic sheet part 4 and the terminal body 1, and the strengthening rib 5 is used for strengthening the elastic sheet part 4.
The terminal body 1, the arm spreading portion 2, the barb portion 3, and the spring portion 4 are integrally formed.
The working principle of the utility model is as follows: when this locking contact terminal that moves is inserting this internal jack of connector, the hook body of overhead kick portion 3 and the contained angle that colludes between the handle reduce, collude the body compression, and the restoring force of production supports contact terminal tightly in the jack to through colluding body and jack inner wall joint, make contact terminal further be fixed in the jack. When external connector inserts, external connector's terminal and this locking contact terminal slides each other to apply an effort to the direction of extracting to this locking contact terminal, at this moment, collude the body and restore the power and with the effect of the frictional force of jack wall under, firmly block the jack inner wall, with this, make the joint of contact terminal and connector body more stable, also prolong the life-span of connector, have the advantage that joint stability is high, simple structure, application scope are wide.
The above description is only for the purpose of illustration and not limitation, and other modifications or equivalent replacements made by those skilled in the art to the technical solution of the present invention should be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
