US 5957708 AAbstract
A type of connector with ejecting and securing functions, comprising a seat body, several pairs of terminals and two catch hooks; on the left and right ends of said seat body is a corresponding catch hook seat; each catch hook seat has two side plates and a center post; on the inside wall of the two side plates is respectively an insert groove; on the inner part of the inner wall of the two side plates is a first positioning body; on the inside wall in said first positioning body is the formation of a matching surface; on two sides of the center post is respectively a guide channel; on the bottom of the guide channel are pinholes; several pairs of terminals are fixed onto the seat body; each catch hook is composed of two side bodies, a pushing part and an ejecting part; on the upper and lower parts of the two side bodies are respectively connected with a pushing part and an ejecting part; on the outside wall of the two side bodies is the insert body; on the lower part inside the two side bodies is a matching surface that corresponds with the matching surface of the catch hook seat; on the upper part of the matching surface is a positioning body that may push against the center part of the first positioning body of the seat body; the two catch hooks are joined by key pins that are inserted into the pinholes of the catch hook seat at two ends of the seat body.
1. A connector with ejecting and securing functions, comprising:a seat body, said seat body comprising an insert slot and a pair of catch hook seats respectively formed on opposing ends of the seat body, each of said catch hook seats having two side plates and a center post, an inside wall of each of the two side plates having an insert groove and a first positioning body formed therein, an inside wall of each first positioning body having a first step-shaped matching surface formed thereon, a guide channel is formed on two sides of the center post, and a pinhole is formed through the center post in open communication with a bottom portion of each guide channel; a plurality of pairs of terminals fixed on the seat body; and two catch hooks, each said catch hook being composed of (a) two side bodies, (b) a pushing part coupled to a respective upper end of said two side bodies, and (c) an ejecting part coupled to a respective lower end of said two side bodies, the pushing part having an inner end facing the insert slot, the inner end having a catching end formed therein, each of the two side bodies having an insert body formed on an outer will thereof for insertion into a respective insert groove of the catch hook seat and a key projecting from an inner wall, each of the two side bodies having a second step-shaped matching surface formed thereon corresponding to the first matching surface of the catch hook seat, said second matching surface having a positioning body protruding therefrom for pushing against a center part of the first positioning body of a respective catch hook seat, said two catch hooks each being joined by insertion of each key into a respective opening of a corresponding one of the pinholes of the pair of catch hook seats. 2. The connector with ejecting and securing function functions, as recited in claim 1, wherein a second positioning body is formed between the two side plates and the center plate of each catch hook seat, each catch hook having a positioning surface that pushes against the second positioning body of the catch hook seat.
As illustrated in FIG. 9 which is a prior art of connector; said connector comprises a seat body 10a, several pairs of terminals 11a and two catch hooks 12a; the terminals 11a are fixed in the seat body 10; the upper parts of the terminals 11a are exposed into the insert groove 13a of the seat body 10a, to facilitate electrical connection with an interface card or other cards; the lower parts of the terminals are exposed to the bottom of the seat body 10a, to facilitate insertion to the circuit board, to achieve the purpose of electrical connection of the insert card with the circuit of the circuit board; on the left and right ends of the seat body 10a is a catch hook seat 16a connected with corresponding catch hook 12a; on the upper and lower ends of the catch hook 12a are respectively a catching part 14a and a ejecting part 15a; said catching part 14a may be secured onto the two sides of the insert card, to increase the steadiness of the insert card. When the top of the catch hook 12a is depressed, the catching part 14a will move away from two sides of the insert card, which will drive the ejecting part 15a at the lower end of the catch hook 12a to move upward, to push the bottom of the insert card, so that the insert card moves upward and away from the seat body 10a of the connector, to enable the separation of the insert card from the connector without using too much force.
The primary purpose of the subject invention is to present a type of connector with ejecting and securing functions; said connector comprises mainly a seat body, several pairs of terminals and two catch hooks; the terminals are fixed onto the seat body; the two catch hooks are connected to the catch hook seat on two ends of the seat body; characterized in the installation of the positioning body inside the two side bodies of the catch hook, that when the pushing part on the upper part of the catch hook is pushed inward, the positioning body will push against the center part with a larger thickness on the first positioning body of the seat body, so the two side bodies of the catch hook will not directly push against the upper part with a smaller thickness on the first positioning body of the seat body; thus to effectively prevent the upper part of the first positioning body of the seat body from damage and breaking; and when the catch hook is securing the insert card, on the outside wall of the two side bodies of the catch hook is an insert body that may be inserted in the insert groove on the inside wall of the two side plates of the catch hook seat of the seat body; so the two catch hooks can be maintained at a securing status, to secure the insert card more steadily; and, on the inside wall of the first positioning body of the catch hook seat of the seat body is a step-shaped matching surface, so that when the ejecting part of the catch hook pushes the insert card upward to a certain extent, the step-shaped matching surface of the two side bodies of the catch hook will push against the matching surface of the catch hook seat and be secured in position; by so design of the step-shaped matching surface and the matching of larger areas, there will be no worry of sliding, and the catch hook will secure more steadily, without causing damage; besides, the edge of the keys of the catch hook is connected with a reinforcing body, to increase the strength and prevent breaking; and with the special design of the catch hook seat, it will prevent breaking, and the integral unit will enable the connector to have an extended service life.
